Agency) has received an application for a Conditional Use Permit prepared by CPT Shops @ Rossmoor, LLC (project proponent) for the development of a health club on the south side of Rossmoor Center Way, west of Seal Beach Boulevard. Approval of the applications constitutes a project that is subject to review under the California Environmental Quality Act (CEQA) 1970 (Public Resources Code, Section 21000 et seq.) and the State CEQA Guidelines (California Code of Regulations, Section 15000 et seq.). This Initial Study has been prepared to assess the short-term, long-term, and cumulative environmental impacts that could result from the proposed health club. This report has been prepared to comply with Section 15063 of the State CEQA Guidelines, which sets forth the required contents of an Initial Study. These include:  A description of the project, including the location of the project (see Section 2)  Identification of the environmental setting (see Section 2.9)  Identification of environmental effects by use of a checklist, matrix, or other methods, provided that entries on the checklist or other form are briefly explained to indicate that there is some evidence to support the entries (see Section 4)  Discussion of ways to mitigate significant effects identified, if any (see Section 4)  Examination of whether the project is compatible with existing zoning, plans, and other applicable land use controls (see Section 4.10)  The name(s) of the person(s) who prepared or participated in the preparation of the Initial Study (see Section 5) 1.1 – Purpose of CEQA The body of state law known as CEQA was originally enacted in 1970 and has been amended a number of times since. The legislative intent of these regulations is established in Section 21000 of the California Public Resources Code, as follows: “The Legislature finds and declares as follows: a) The maintenance of a quality environment for the people of this state now and in the future is a matter of statewide concern. b) It is necessary to provide a high-quality environment that at all times is healthful and pleasing to the senses and intellect of man. c) There is a need to understand the relationship between the maintenance of high-quality ecological systems and the general welfare of the people of the state, including their enjoyment of the natural resources of the state. d) The capacity of the environment is limited, and it is the intent of the Legislature that the government of the state take immediate steps to identify any critical thresholds for the health and safety of the people of the state and take all coordinated actions necessary to prevent such thresholds being reached. e) Every citizen has a responsibility to contribute to the preservation and enhancement of the environment. f) The interrelationship of policies and practices in the management of natural resources and waste disposal requires systematic and concerted efforts by public and private interests to enhance environmental quality and to control environmental pollution. g) It is the intent of the Legislature that all agencies of the state government which regulate activities of private individuals, corporations, and public agencies which are found to affect the quality of the environment, shall regulate such activities so that major consideration is given Introduction 2 Initial Study to preventing environmental damage, while providing a decent home and satisfying living environment for every Californian. The Legislature further finds and declares that it is the policy of the State to: h) Develop and maintain a high-quality environment now and in the future, and take all action necessary to protect, rehabilitate, and enhance the environmental quality of the state. i) Take all action necessary to provide the people of this state with clean air and water, enjoyment of aesthetic, natural, scenic, and historic environmental qualities, and freedom from excessive noise. j) Prevent the elimination of fish or wildlife species due to man's activities, insure that fish and wildlife populations do not drop below self-perpetuating levels, and preserve for future generations representations of all plant and animal communities and examples of the major periods of California history. k) Ensure that the long-term protection of the environment, consistent with the provision of a decent home and suitable living environment for every Californian, shall be the guiding criterion in public decisions. l) Create and maintain conditions under which man and nature can exist in productive harmony to fulfill the social and economic requirements of present and future generations. m) Require governmental agencies at all levels to develop standards and procedures necessary to protect environmental quality. n) Require governmental agencies at all levels to consider qualitative factors as well as economic and technical factors and long-term benefits and costs, in addition to short-term benefits and costs and to consider alternatives to proposed actions affecting the environment.” A concise statement of legislative policy, with respect to public agency consideration of projects for some form of approval, is found in Section 21002 of the Public Resources Code, quoted below: “The Legislature finds and declares that it is the policy of the state that public agencies should not approve projects as proposed if there are feasible alternatives or feasible mitigation measures available which would substantially lessen the significant environmental effects of such projects, and that the procedures required by this division are intended to assist public agencies in systematically identifying both the significant effects of proposed projects and the feasible alternatives or feasible mitigation measures which will avoid or substantially lessen such significant effects. The Legislature further finds and declares that in the event specific economic, social, or other conditions make infeasible such project alternatives or such mitigation measures, individual projects may be approved in spite of one or more significant effects thereof.” 1.2 – Public Comments Comments from all agencies and individuals are invited regarding the information contained in this Initial Study.

The project site is located on the northwestern most portion of the shopping center parking lot on Rossmoor Center Way between Seal Beach Boulevard and Montecito Road (see Exhibit 1, Regional Context and Vicinity Map). The site is bounded by residential uses to the west and north, a Sprouts grocery store and Marshall’s department store to the east, and the retail stores Home Goods and PetSmart to the south (see Exhibit 2, Site Plan). 2.5 – Project Sponsor’s Name and Address CPT Shops at Rossmoor, LLC Two Seaport Lane Boston, MA 02210-2021 2.6 – General Plan Land Use Designation Commercial General 2.7 – Zoning District GC – General Commercial 2.8 – Project Description The proposed project includes the construction of a 37,000-square-foot private health club on approximately 5.28 acres within the existing Shops at Rossmoor retail development (see Exhibit 2, Site Plan). Project Description 6 Initial Study Project Design The proposed project is a single-story private health club comprising 37,000 square feet of floor space. Facilities in the health club would include free weights, circuit training, a pool, a basketball court, separate rooms for aerobics and spinning, a personal training room, men’s and women’s showers and lockers, a hot yoga studio, a physical therapy room, and a children’s area (see Exhibit 3, Floor Plan). Through previous entitlements acquired by the Shops at Rossmoor from the City, the commercial center currently has 2,068 existing parking spaces. With completion of the proposed project, the total number of parking spaces in the center will be reduced to 1,981 spaces. With the proposed project a total of 1,645 spaces are required at the Shops at Rossmoor. Thus, adequate parking supply within the Shops at Rossmoor will be provided. Currently, the immediate vicinity of the Shops at Rossmoor serving the site has 445 parking stalls that serve the entire shopping center. Development of the project would result in a net decrease of approximately 40 parking stalls, leaving 405 parking stalls at project completion. Because the project would be constructed on an existing parking lot, construction of the health club would require the removal of 87,500 square feet of existing asphalt surfaces, installation of 56,800 square feet of new asphalt surface, application of 119,065 square feet of slurry fill on the existing undisturbed asphalt, and restriping the entire 175,865-square-foot parking lot once the health club center is constructed. The project site plan includes 16,795 square feet of ornamental landscaping around the perimeter of the health club and within parking lot planters. Architecturally (see Exhibit 4, Project Elevations), the building would consist of a painted concrete tilt-up wall system accented with a prefabricated metal panel shell finish system. The entryway would consist of anodized aluminum. Painted plaster and simulated wood paneling would also be used on the building exterior. An internally illuminated sign with 40-inch-high letters will adorn the building façade on the south side. The building would have a stepped massing from 24 feet in height at the side and rear to 28 feet at the entryway to 35 feet at the highest point of the parapet holding the illuminated sign. The molding along the top of the building and arcade features would be finished with decorative cornices. Finally, images portraying individuals engaging in physical fitness activities are proposed to be placed on the rear and side building elevations. Circulation Vehicular access to the health club would be provided from Rossmoor Center Way via two existing driveways: a 40-foot-wide driveway just west of the proposed project site (which will be converted to a 36-foot driveway to accommodate proposed new parking), and a 36-foot-wide driveway just east of the proposed project site. Both driveways currently provide ingress and egress in a north-south direction into and out of the Shops at Rossmoor shopping center onto Rossmoor Center Way. Entrance to the site is also provided via a 44-foot-wide entrance on Seal Beach Boulevard. All three of these driveways will provide direct access into the center of the project site for both future users of the site and emergency services. In its existing condition, the 40-foot-wide driveway (west of the proposed health club) is flanked on the west side by a sidewalk that runs for 350 feet parallel to the drive aisle. This barrier forms an enclosed area west of the proposed project site. Residents of the condominiums to the west and north use have been observed to park in this area, as well as the proposed project site. However, parking by residents is not authorized. Easier access to this area will be provided via a 36-foot wide access cut in the existing curb barrier. Additional curb barriers would be provided within the site to provide a separation between north and south sections of the parking lot. The shopping center operator proposes this configuration to encourage patrons visiting the Home Goods and PetSmart retail stores to park close to those locations and visitors to the health club to park close to that use. Project Description Rossmoor Health Club 7 Utilities The site is fully served by utilities. An eight-inch water main runs west along Rossmoor Center Way before turning south under the existing 40-foot-wide driveway east of the project site. This main also serves the adjacent condominium development. Project construction would necessitate the capping of the existing water main under the proposed project site, extending the main under the 40-foot-wide driveway farther south, and constructing a new eight-inch main to run west from the driveway approximately 100 feet south and perpendicular to the existing main. Lateral connections would be made to this new water main. Project Operation The health club would provide membership-based fitness services, including access to exercise equipment, group fitness classes, and personal fitness training. The health club is proposed to operate seven days a week. Hours of operation would be 5:00 A.M. to 11:00 P.M. Monday through Thursday, 5:00 A.M. to 10:00 P.M. on Fridays, and 8:00 A.M. to 8:00 P.M. on Saturdays and Sundays. Off-Site Improvements A traffic analysis was prepared by LSA Associates, Inc. to identify any potential traffic and parking impacts resulting from the development of the proposed health club. The traffic analysis found that all study area facilities are anticipated to operate at satisfactory conditions per City standards. However, the analysis did find that the northbound left-turn pocket at the intersection of Seal Beach Boulevard and Rossmoor Center Way currently experiences queuing issues and would require improvements. The intersection is bounded by a landscaped median along Seal Beach Boulevard and a southbound left-turn pocket that provides access to the Target shopping center southeast of the intersection. The northbound left-turn movement currently experiences queuing that extends past the existing left-turn pocket during periods of peak demand. Improvements to the existing configuration is proposed to handle additional queuing that results from the project. This issue and improvements are discussed in Section 4.16 of this Initial Study. Project Construction Project construction is anticipated to begin in late 2016 or early 2017, with completion by mid- 2017. Construction would require demolition of existing asphalt paving on the project site. Construction program defaults were used for air quality and greenhouse gas emissions for a conservative estimate of timeframes and resulting emissions. The default construction schedule is as follows: Phase Total Days Demolition 20 Site Preparation 10 Grading 20 Building Construction 63 Paving 20 Architectural Coating 20 2.9 – Environmental Setting The project site is located within a built-out and completely urbanized area along Seal Beach Boulevard and Rossmoor Center Way. The project site currently is used as parking for the Shops at Rossmoor. The project site is surrounded by commercial and residential land uses, and the area is completely urbanized. Nominal ornamental landscaping is located on the existing parking area. The project site sits at an elevation of approximately 16 feet above sea level on land that slopes gently in a westerly direction. Project Description 8 Initial Study The proposed project site currently is an asphalt parking lot that provides parking for the Shops at Rossmoor shopping center. The Shops at Rossmoor is located in the City of Seal Beach. Surrounding uses include single-family residential, multifamily, and commercial.

I find that although the proposed project could have a significant effect on the environment, there will not be a significant effect in this case because revisions in the project have been made by or agreed to by the project proponent. A MITIGATED NEGATIVE DECLARATION will be prepared. □I find that the proposed project MAY have a significant effect on the environment, and an ENVIRONMENTAL IMPACT REPORT is required. □I find that the proposed project MAY have a ‘potentially significant impact’ or ‘potentially significant unless mitigated’ impact on the environment, but at least one effect 1) has been adequately analyzed in an earlier document pursuant to applicable legal standards, and 2) has been addressed by mitigation measures based on the earlier analysis as described on attached sheets. An ENVIRONMENTAL IMPACT REPORT is required, but it must analyze only the effects that remain to be addressed. □I find that although the proposed project could have a significant effect on the environment, because all potentially significant effects (a) have been analyzed adequately in an earlier EIR or NEGATIVE DECLARATION pursuant to applicable standards, and (b) have been avoided or mitigated pursuant to that earlier EIR or NEGATIVE DECLARATION, including revisions or mitigation measures that are imposed upon the proposed project, nothing further is required. Name: Crystal Landavazo, Senior Planner Date Laura Stetson, AICP, Principal FOR 6/9/2016 Determination 18 Initial Study  19 Initial Study 4 Evaluation of Environmental Impacts 4.1 – Aesthetics Would the project: Potentially Significant Impact Less Than Significant with Mitigation Incorporation Less Than Significant Impact No Impact a) Have a substantial adverse effect on a scenic vista? □ □ □ b) Substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic buildings within view from a state scenic highway? □ □ □ c) Substantially degrade the existing visual character or quality of the site and its surroundings? □ □ □ d) Create a new source of substantial light or glare which would adversely affect day or nighttime views in the area? □ □ □ This aesthetics impact analysis is based on review of project maps and drawings, aerial and ground-level photographs of the project area, renderings of the proposed project, and planning documents. The site is most visible from neighboring properties, as well as by pedestrians and motorists along Rossmoor Center Way. East and south of the subject property are retail stores within the Shops at Rossmoor development. West and north are multifamily residential developments. a) No Impact. Scenic vistas can be impacted by development in two ways. First, a structure may be constructed that blocks the view of a vista. Second, the vista itself may be altered (i.e., development on a scenic hillside). The City of Seal Beach General Plan does not designate any locations within the City as a scenic vista. However, the County of Orange has designated Pacific Coast Highway as an “Urbanscape Corridor.” Urbanscape Corridors, as defined by the County, are routes that traverse an urban area with a defined visual corridor that offers a view or attractive and exciting urban scene, and that has recreational value for its visual relief as a result of nature or the designed efforts of man.1 The proposed project is located on a developed site within a fully urbanized area visually dominated by commercial land uses and surface street features. This site is not considered to be 1 City of Seal Beach. Seal Beach General Plan Land Use Element. pp. LU-64. December 2003. Evaluation of Environmental Impacts 20 Initial Study within or to comprise a portion of a scenic vista as defined by the City and the County. The project is located approximately two miles from Pacific Coast Highway. Development of the health club with the proposed two-story building, parking, and accessory landscaping elements would have no effect on a scenic vista. The proposed development is generally consistent in type and scale with the existing and planned surrounding development. No impact would occur. b) No Impact. The project is not adjacent to a designated State Scenic Highway or eligible State Scenic Highway, as identified on the California Scenic Highway Mapping System.2 Thus, the proposed project would not damage the integrity of existing visual resources or historic buildings located along a State Scenic Highway. The City’s General Plan does not identify any local scenic roadways within the City limits. The County of Orange has designated Pacific Coast Highway as an “Urbanscape Corridor.” However, the proposed project is not located in the immediate vicinity of this Urbanscape Corridor. The project site is currently developed with parking used for the Shops at Rossmoor development and contains no scenic resources. No impact on scenic resources, including but not limited to, trees, rock outcroppings, and historic buildings within a State Scenic Highway, would result. Therefore, no impact to scenic resources visible from a State Scenic Highway would occur. c) Less Than Significant Impact. Development of the proposed project could result in a significant impact if it resulted in substantial degradation of the existing visual character or quality of the site and its surroundings. Degradation of visual character or quality is defined by substantial changes to the existing site appearance through construction of structures such that they are poorly designed or conflict with the site’s existing surroundings. Construction of the proposed project could result in short-term impacts to the existing visual character and quality of the area. Construction activities would require the use of equipment and storage of materials within the project site. However, a construction fence will be erected around the site to avoid any temporary visual impact. Project construction would result in the removal of decorative planter trees and asphalt pavement. The project would include ornamental trees and bushes of varying species around the edge of the building. A total of 16,795 square feet of landscaped area would be provided to replace any landscaping removed. Construction of the proposed buildings on the developed site would alter the existing visual character of the site. Upon project completion, the proposed building would consist of a single building, containing one story and a mezzanine, constructed adjacent to Rossmoor Center Way to the north. The building height would vary due to parapets and variation in roof level (see Exhibit 4, Project Elevations). However, no part of the building would exceed 35 feet in height. The proposed project is zoned General Commercial, which has a maximum building height of 35 feet. The proposed building is 24 feet in height, with accents up to 35 feet tall. The proposed project is similar in use and building type to the existing surrounding buildings in the Shops at Rossmoor shopping center. The immediate surroundings along Seal Beach Boulevard and Rossmoor Center Way are occupied by commercial uses. To the west and east are high-density residential units. The design of the health club would consist of a painted concrete tilt-up wall system accented with a prefabricated metal panel shell finish system. The entryway would consist of anodized 2 California Department of Transportation. California Scenic Highway Mapping System: Los Angeles County. Accessed March 2015. Evaluation of Environmental Impacts Rossmoor Health Club 21 aluminum. Painted plaster and simulated wood paneling would also be used. An internally illuminated sign with 40-inch-high letters would adorn the south building façade. The building would have a stepped massing from 24 feet in height at the side and rear to 28 feet at the entryway to 35 feet at the highest point of the parapet holding the illuminated sign. The molding along the top of the building and arcade features would be finished with decorative cornices. Images portraying people engaging in physical fitness activities are proposed on rear and side building elevations. The project proposes landscaping features around the sides and rear of the building and along Rossmoor Center Way. Project plans include additional landscaping and shade trees within the reconfigured parking lot. This landscaping would visually break up the expanse of asphalt. The proposed project would maintain the visual urban character of the project vicinity and enhance the existing parking lot with landscaping and a building compatible with surrounding development. With specified design features included, project impact would be less than significant on the visual character of the site and surroundings. d) Less Than Significant Impact. Excessive or inappropriately directed lighting can adversely impact night-time views by reducing the ability to see the night sky and stars. Glare can be caused from unshielded or misdirected lighting sources. Reflective surfaces (i.e., polished metal) can also cause glare. Impacts associated with glare range from simple nuisance to potentially dangerous situations (i.e., if glare is directed into the eyes of motorists). Lighting sources adjacent to this site include freestanding streetlights, light fixtures on buildings, pole-mounted lights, traffic signals, and vehicle headlights. The proposed project would include exterior parking lot and security lighting and building interior lighting. However, only outdoor lighting could have any effect on neighboring land uses since interior lighting would be reduced by tinted windows. The proposed project would be required to conform to existing City lighting standards for commercial uses which require lighting to be directed downward and away from adjacent properties. Light impacts would be less than significant with compliance with City standards. Sources of daytime glare are typically concentrated in commercial areas, such as in the vicinity of the project site, which is one of the City’s primary commercial areas, and are often associated with retail uses. Glare results from development and associated parking areas that contain reflective materials such as glass, highly polished surfaces, and expanses of pavement. The proposed building would have a sand stucco finish, which is not a surface that causes glare. While windows may contribute to glare impacts, they do not compose substantial square footage of the façade and are included as architectural treatments to enhance aesthetic quality. Limited metal accents are proposed on the crown and canopy; however, these areas represent a minor percentage of the square footage of the building. Given the minimal use of glare-inducing materials in the design of the proposed building, reflective glare impacts would be less than significant. Evaluation of Environmental Impacts 22 Initial Study 4.2 – Agriculture and Forest Resources Would the project: Potentially Significant Impact Less Than Significant with Mitigation Incorporation Less Than Significant Impact No Impact a) Convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance (Farmland), as shown on the maps prepared pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency, to non-agricultural use? □ □ □ b) Conflict with existing zoning for agricultural use, or a Williamson Act contract? □ □ □ c) Conflict with existing zoning for, or cause rezoning of, forest land (as defined in Public Resources Code section 12220(g)), timberland (as defined by Public Resources Code section 4526), or timberland zoned Timberland Production (as defined by Government Code section 51104 (g))? □ □ □ d) Result in loss of forest land or conversion of forest land to non-forest use? □ □ □ e) Involve other changes in the existing environment which, due to their location or nature, could result in conversion of Farmland to non- agricultural use or conversion of forest land to non-forest use? □ □ □ a-b) No Impact. The proposed project would be located in a fully developed, commercial, urbanized area that does not contain agriculture or forest uses.

No impact would occur. c) No Impact. Public Resources Code Section 12220(g) identifies forest land as “land that can support 10-percent native tree cover of any species, including hardwoods, under natural conditions, and that allows for management of one or more forest resources, including timber, aesthetics, fish and wildlife, biodiversity, water quality, recreation, and other public benefits.” The project site and surrounding properties are not currently being managed or used for forest land as identified in Public Resources Code Section 12220(g). The USDA Forest Service vegetation maps for the project site identify it as urban type, indicating that it is not capable of growing industrial wood tree species.5 The project site has already been graded and developed with commercial uses, with no substantial vegetation onsite, with the exception of limited ornamental landscaping. Therefore, development of this project would have no impact to any timberland zoning. d) No Impact. The project site is already graded land with existing development and limited ornamental landscaping; thus, there would be no loss of forest land or conversion of forest land to non-forest use as a result of this project. No impact would occur. e) No Impact. The project site is a developed site within an urban environment and is surrounded by commercial and residential uses. The project would not encroach onto agricultural land nor encourage the conversion of existing farmland to non-agricultural uses. None of the surrounding sites contain existing forest uses. Development of this project would not change the existing environment in a manner that will result in the conversion of forest land to a non-forest use. No impact would occur. 4 California Department of Conservation. Williamson Act Program, 2007. 5 California Department of Forestry and Fire Protection and the USDA Forest Service.

EvegTile51A__02_03_v2. 2007 Evaluation of Environmental Impacts 24 Initial Study 4.3 – Air Quality Where available, the significance criteria established by the applicable air quality management or air pollution control district may be relied upon to make the following determinations. Would the project: Potentially Significant Impact Less Than Significant with Mitigation Incorporation Less Than Significant Impact No Impact a) Conflict with or obstruct implementation of the applicable air quality plan? □ □ □ b) Violate any air quality standard or contribute substantially to an existing or projected air quality violation? □ □ □ c) Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non-attainment under an applicable federal or state ambient air quality standard (including releasing emissions which exceed quantitative thresholds for ozone precursors)? □ □ □ d) Expose sensitive receptors to substantial pollutant concentrations? □ □ □ e) Create objectionable odors affecting a substantial number of people? □ □ □ a) No Impact. A significant impact could occur if the proposed project conflicts with or obstructs implementation of the South Coast Air Basin 2007 Air Quality Management Plan. Conflicts and obstructions that hinder implementation of the AQMP can delay efforts to meet attainment deadlines for criteria pollutants and maintaining existing compliance with applicable air quality standards. Pursuant to the methodology provided in Chapter 12 of the 1993 SCAQMD CEQA Air Quality Handbook, consistency with the South Coast Air Basin 2007 Air Quality Management Plan (AQMP) is affirmed when a project (1) does not increase the frequency or severity of an air quality standards violation or cause a new violation and (2) is consistent with the growth assumptions in the AQMP.6 Consistency review is presented below. 6 South Coast Air Quality Management District. CEQA Air Quality Handbook. 1993. Evaluation of Environmental Impacts Rossmoor Health Club 25 (1) The project would result in short-term construction and long-term pollutant emissions that are less than the CEQA significance emissions thresholds established by the SCAQMD, as demonstrated in Section 4.3 et seq. of this Initial Study; therefore, the project would not result in an increase in the frequency or severity of any air quality standards violation and would not cause a new air quality standard violation. (2) The CEQA Air Quality Handbook indicates that consistency with AQMP growth assumptions must be analyzed for new or amended General Plan elements, Specific Plans, and significant projects. Significant projects include airports, electrical generating facilities, petroleum and gas refineries, designation of oil drilling districts, water ports, solid waste disposal sites, and off-shore drilling facilities. This project, construction of a health club facility, does not involve a General Plan Amendment, Specific Plan, and is not considered a significant project. Based on the consistency analysis presented above, the proposed project would not conflict with the AQMP; no impact will occur. b) Less Than Significant Impact. A project may have a significant impact if project-related emissions would exceed federal, state, or regional standards or thresholds, or if project-related emissions would substantially contribute to existing or project air quality violations. The proposed project is located within the South Coast Air Basin, where efforts to attain state and federal air quality standards are governed by the South Coast Air Quality Management District (SCAQMD). Both the State of California and the federal government have established health-based ambient air quality standards (AAQS) for seven air pollutants (known as “criteria pollutants”). These pollutants include ozone (O3), carbon monoxide (CO), nitrogen dioxide (NO2), sulfur dioxide (SO2), inhalable particulate matter with a diameter of 10 microns or less (PM10), fine particulate matter with a diameter of 2.5 microns or less (PM2.5), and lead (Pb). The state has also established AAQS for additional pollutants. The AAQS are designed to protect the health and welfare of the populace within a reasonable margin of safety. Where the state and federal standards differ, California AAQS are more stringent than the national AAQS. Air pollution levels are measured at monitoring stations located throughout the air basin. Areas that are in nonattainment with respect to federal or state AAQS are required to prepare plans and implement measures that will bring the region into attainment. Table 1 (South Coast Air Basin Attainment Status – Orange County) summarizes the attainment status in the project area for the criteria pollutants. Discussion of potential impacts related to short-term construction impacts and long-term area source and operational impacts are presented below. Table 1 South Coast Air Basin Attainment Status – Orange County Pollutant Federal State O3 (1-hr) N/A Nonattainment O3 (8-hr) Nonattainment Nonattainment PM10 Nonattainment Nonattainment PM2.5 Nonattainment Nonattainment CO Attainment Attainment NO2 Attainment Nonattainment SO2 Attainment Attainment Pb Nonattainment Nonattainment Sources: CARB 2011, U.S. EPA 2012 Evaluation of Environmental Impacts 26 Initial Study Construction Emissions The California Emissions Estimator Model (CalEEMod) version 2013.2.2 was utilized to estimate emissions from the proposed construction activities. CalEEMod default construction phase lengths were utilized. The maximum (summer or winter) results of the analysis are summarized in Table 2 (Unmitigated Maximum Daily Construction Emissions). The model indicates that no criteria pollutants would exceed the daily emissions thresholds established by SCAQMD; therefore, construction impacts would be less than significant.

No No No No No No Source: MIG 2015 Note: Volatile organic compounds are measured as reactive organic compounds Operational Emissions Long-term criteria air pollutant emissions would result from the operation of the health club. Long-term emissions are categorized as area source emissions, energy demand emissions, and operational emissions. Operational emissions would result from automobile and other vehicle sources associated with daily trips to and from the proposed health club. The CalEEMod modeling program was utilized to estimate mobile source emissions. Trip generation is based on the traffic analysis prepared by LSA Associates, Inc.7 Area source emissions are the combination of many small emission sources that include use of outdoor landscape maintenance equipment, use of consumer products such as cleaning products, and periodic repainting of the proposed structure. Energy demand emissions result from use of electricity and natural gas. Emissions from area sources were estimated using CalEEMod using program default values for area and energy demand emissions. Operational emissions are summarized in Table 3 (Long-Term Daily Emissions). Long-term emissions would not exceed the daily thresholds established by SCAQMD; impacts would be less than significant. 7 LSA Associates, Inc.

No No No No No No Source: MIG 2015 Note: Volatile organic compounds are measured as reactive organic compounds c) Less Than Significant Impact. Cumulative short-term, construction-related emissions and long-term, operational emissions from the project would not contribute considerably to any potential cumulative air quality impact because short-term project and operational emissions would not exceed any SCAQMD daily threshold. As is required of the proposed project, other concurrent construction projects and operations in the region would be required to implement standard air quality regulations and mitigation pursuant to State CEQA requirements. Such measures include compliance with SCAQMD Rule 403, which requires daily watering to limit dust and particulate matter emissions. Impacts would be less than significant. d) Less Than Significant Impact. Sensitive receptors are those segments of the population that are most susceptible to poor air quality, such as children, the elderly, the sick, and athletes who perform outdoors. Land uses associated with sensitive receptors include residences, schools, playgrounds, childcare centers, outdoor athletic facilities, long-term health care facilities, rehabilitation centers, convalescent centers, and retirement homes. The nearest land uses that considered sensitive receptors are the residential dwelling units located adjacent to the project site to the north and west. No schools are located within a quarter-mile of the project site. The proposed health club would not generate toxic pollutant emissions because the proposed fitness and gymnasium uses are characterized as typical commercial uses that do not produce such emissions. The proposed health club, therefore, would have a less than significant impact on sensitive receptors relating to toxic pollutant emissions. A CO hotspot is an area of localized CO pollution that is caused by severe vehicle congestion on major roadways, typically near intersections. CO hotspots have the potential for violation of state and federal CO standards at study area intersections, even if the broader Basin is in attainment for federal and state levels. The potential for violation of state and federal CO standards at study area intersections and exposure to sensitive receptors at those intersections is addressed using the methodology outlined in the California Department of Transportation Project-Level Carbon Monoxide Protocol. Section numbers for the CO Protocol are provided in parenthesis for ease of reference. In general, SCAQMD and the California Department of Transportation Project-Level Carbon Monoxide Protocol recommend analyzing CO hotspots when a project has the potential to result in higher CO concentrations within the region and increase traffic congestion at an intersection operating at level of service (LOS) D or worse by more than two percent. Evaluation of Environmental Impacts 28 Initial Study There has been a decline in CO emissions over the past two decades even though vehicle miles traveled on U.S. urban and rural roads have increased. Three major control programs have contributed to the reduced per vehicle CO emissions: exhaust standards, cleaner-burning fuels, and motor vehicle inspection/maintenance programs. Local impacts from the project need to be examined because the project is not exempt from emissions analysis as defined by the CO Protocol (3.1.1, 3.1.2, 3.1.9). According to the CO Protocol, projects may worsen air quality if they significantly increase the percentage of vehicles in cold start modes (by two percent or more), significantly increase traffic volumes (by five percent or more) over existing volumes, or reduce average speeds on uninterrupted roadway segments (increase delays at intersections for interrupted roadway segments) (4.7.1). Based on the project traffic analysis that identifies net traffic volume changes between the existing parking use and the proposed health club, the proposed project would not increase vehicles operating in cold start mode in the morning, evening, or Saturday peak hours by more than two percent at any of traffic study intersections; therefore, impacts to sensitive receptors due to localized CO emissions would be less than significant. e) No Impact. According to the CEQA Air Quality Handbook, land uses associated with odor complaints include agricultural operations, wastewater treatment plants, landfills, and certain industrial operations (such as manufacturing uses that produce chemicals, paper, etc.). Odors are typically associated with industrial projects involving the use of chemicals, solvents, petroleum products, and other strong-smelling elements used in manufacturing processes, as well as sewage treatment facilities and landfills. The proposed health club does not include any of the above noted uses or process; no impact would occur. Evaluation of Environmental Impacts Rossmoor Health Club 29 4.4 – Biological Resources Would the project: Potentially Significant Impact Less Than Significant with Mitigation Incorporation Less Than Significant Impact No Impact a) Have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special status species in local or regional plans, policies, or regulations, or by the California Department of Fish and Game or U.S. Fish and Wildlife Service? □ □ □ b) Have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, regulations, or by the California Department of Fish and Game or US Fish and Wildlife Service? □ □ □ c) Have a substantial adverse effect on federally protected wetlands as defined by Section 404 of the Clean Water Act (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means? □ □ □ d) Interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites? □ □ □ e) Conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance? □ □ □ Evaluation of Environmental Impacts 30 Initial Study f) Conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat conservation plan? □ □ □ a) No Impact. The project site is currently developed with an asphalt parking lot associated with the Shops at Rossmoor shopping center. A number of ornamental trees exist in planters throughout the parking lot. The ornamental trees do not support habitat of any species identified as a candidate, sensitive, or special status species. The project site is not identified as critical habitat for Threatened and Endangered Species.8 Considering the highly developed nature of the project site and surrounding areas, the probability of existence of designated species under the federal Endangered Species Act or California Special Concern Species is very low. The proposed project would, therefore, not have a substantial adverse effect on any species identified as a candidate, sensitive, or special-status species in local or regional plans or by the California Department of Fish and Wildlife or U.S. Fish and Wildlife Service. Considering the lack of habitat on the property, no impacts to wildlife species of concern would occur. b) No Impact. The project site is located on land that has been previously developed in a primarily commercial portion of the City. The site has been graded and developed, with limited landscaping consisting of non-native, ornamental trees. The site is entirely paved. There is no riparian habitat onsite. As such, no impact to riparian habitat or other sensitive natural habitat would occur. c) No Impact. According to the federal National Wetlands Inventory, the project site does not contain any wetlands;9 furthermore, the proposed project would not disturb any offsite wetlands, as no wetlands are adjacent to the project site. (See Section 4.9 for discussion of project drainage features.) There is no vegetation or on-site water features indicative of potential wetlands. No impact would occur. d) No Impact. The project site is currently developed with surface parking and is surrounded by commercial and residential development, preventing the use of the site and surrounding area as a wildlife corridor. The project site contains limited ornamental vegetation in the form of planter trees, in the context of a completely urbanized setting located along one of the City’s major commercial thoroughfares. There are no substantial vegetated areas or water bodies located on site. The project site does not provide for the movement of any native resident or migratory fish or wildlife. No impact would occur. e) Less than Significant Impact. The City of Seal Beach has a tree ordinance (Municipal Code Chapter 9.40) that regulates the planting, trimming, and removal of trees on City property. Trees on private property are not regulated. The small ornamental trees located in planters throughout the parking lot will be removed to facilitate construction of the health club and associated parking improvements. The proposed project would include landscaping and ornamental trees around the perimeter of the building and in proposed new parking lot 8 U.S. Fish and Wildlife Service.

This property does not satisfy any of the criteria for a historic resource defined in Section 15064.5 of the State CEQA Guidelines. The proposed property has been previously disturbed and currently is used as surface parking for the Shops at Rossmoor shopping center. No known historically or culturally significant resources, structures, buildings, or objects are located on the project site. As such, the proposed project would not cause an adverse change in the significance of a historical resource, and impacts to historic resources are not anticipated. No impact would occur. b-c) Less Than Significant Impact. The property is a previously developed site in a fully urbanized area. According to the City’s General Plan, Anaheim Bay, the San Gabriel Estuary, and the Seal Beach area have supported several cultures over the past 10,000 years. Prehistoric occupation of the Seal Beach area was associated with the Tongva (Gabrielino) Native Americans, who inhabited much of northern Orange County. Tongva coastal villages have been identified in Long Beach, Seal Beach, Huntington Beach, and Costa Mesa. Identified within Seal Beach, a Tongva community named Motuuchey, also known as “El Piojo” (The Louse), was located at the former Anaheim landing area. Identified archaeological resources within the City of Seal Beach are primarily located on the Naval Weapons Station, the Hellman Ranch property, and potentially the Boeing property.12 No known archaeological or paleontological sites are documented within the Rossmoor Center planning area. The potential for uncovering such significant resources at the project site during construction activities is considered remote given that no such resources have been discovered during prior development activity within the area, there are no unique geological resources on or 12 City of Seal Beach.

Evaluation of Environmental Impacts Rossmoor Health Club 33 near the project site, and the fact that the site has been significantly disturbed in the past for construction of the existing development. Only minor excavation requirements into fill materials of this previously developed site would be necessary; therefore, it is considered unlikely that archeological or paleontological resources would be found. In accordance with standard City procedures, a halt-work condition would be in place in the unlikely event that archaeological or paleontological resources are discovered during construction. The contractor would be required to halt work in the immediate area of the find and to retain a professional archaeologist or paleontologist, as applicable, to examine the materials to determine whether they are a “unique archaeological resource” as defined in Section 21083.2(g) of the State CEQA Statutes. If this determination is positive, the scientifically consequential information must be fully recovered by the archaeologist or paleontologist, as applicable, consistent with standard City protocol. As such, impacts on archeological and/or paleontological impacts would be less than significant with adherence to existing standards and regulations. d) Less Than Significant Impact. It is unlikely that human remains could be uncovered during grading operations, considering that the project site was previously disturbed during construction of the Shops at Rossmoor shopping center. Nonetheless, should suspected human remains be encountered, the contractor shall be required to notify the County Coroner in accordance with Section 7050.5 of the California Health and Safety Code, who must then determine whether the remains are of forensic interest. If the coroner, with the aid of a supervising archaeologist, determines that the remains are or appear to be of a Native American, he/she would be required to contact the Native American Heritage Commission for further investigations and proper recovery of such remains, if necessary. Through this existing regulatory procedure, impacts to human remains would be avoided. Impact would be less than significant with application of existing regulations. Evaluation of Environmental Impacts 34 Initial Study 4.6 – Geology and Soils Would the project: Potentially Significant Impact Less Than Significant with Mitigation Incorporation Less Than Significant Impact No Impact a) Expose people or structures to potential substantial adverse effects, including the risk of loss, injury, or death involving: i) Rupture of a known earthquake fault, as delineated on the most recent Alquist-Priolo Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a known fault?

Although the project site is located in seismically active Southern California, according to the California Geological Survey Alquist-Priolo Earthquake Fault Zone Map for the Los Alamitos quadrangle, the site is not located within an Alquist-Priolo Earthquake Fault Zone.13 The nearest Alquist-Priolo fault zone is the Newport-Inglewood Fault, located approximately two miles southwest of the project site. No impact would occur. a.ii) Less Than Significant Impact. The proposed project would be subject to ground shaking impacts should a major earthquake occur in the future. Potential impacts include injury or loss of life and property damage. The project site is located within proximity to the Newport-Inglewood Fault. Significant ground shaking may occur if an earthquake were to occur along that fault line. Other local faults can also cause significant groundshaking. Other nearby faults which present seismic risks include the Cabrillo and Palos Verdes faults.14 The project site is subject to strong seismic ground shaking, as are virtually all lands in Southern California. The proposed building would be required to be designed consistent with seismic design criteria of the California Building Code (CBC) and the project-specific design requirements of the project geotechnical report 15 The project geotechnical report recommends site class designation D for seismic design of the proposed building, given the predominance of stiff soils located on the project site. The 2013 CBC (Title 14, California Code of Regulations, Part 2) contains seismic safety provisions purposed to prevent building collapse during a design earthquake. Adherence to these requirements will reduce the potential of the building from collapsing during an earthquake, thereby minimizing injury and loss of life. The recommendations of the geotechnical report would be implemented during preparation of construction drawings for review and approval of the City. Adherence to existing regulations would reduce the risk of loss, injury, and death; impacts due to strong ground shaking would be less than significant. a.iii) Less Than Significant Impact. Liquefaction is a phenomenon that occurs when soil undergoes transformation from a solid state to a liquefied condition due to the effects of increased pore-water pressure. This typically occurs where susceptible soils (particularly the medium sand to silt range) are located over a high groundwater table. Affected soils lose all strength during liquefaction and foundation failure can occur. According to the Seismic Hazard Evaluation of the Los Alamitos 7.5-minute quadrangle, the site is located in Zone of Required Investigation for liquefaction.16 This indicates that the area has been subject to historic occurrence of liquefaction, or local geological, geotechnical, and groundwater conditions indicate a potential for permanent ground displacement such that mitigation as defined 13 California State Department of Conservation.

Los Alamitos Quadrangle, March 25, 1999. Evaluation of Environmental Impacts 36 Initial Study in Public Resources Code Section 2693(c) would be required. During geotechnical investigation of the site, groundwater was measured at a depth of 12 feet. However, the report found that the majority of the clays found on site do not exhibit a potential for liquefaction. Liquefaction potential is not considered to be a design issue at this site; therefore, impacts would be less than significant. a.iv) Less than Significant Impact. Structures built below or on slopes subject to failure or landslides may expose people and structures to harm. The project site topography is generally flat. The project geotechnical report concluded that because the on-site soils are predominantly cohesive (silts and clays) or medium dense, silty sands, mitigation of landslide hazards is not necessary for the site. The geotechnical report noted that some slope stability problems are expected in steep, unbraced excavations. Deeper excavations may require external support such as shoring or bracing. Grading and construction would be performed in compliance with State and local codes and the recommendations of the geotechnical report. Impacts would be less than significant. b) Less Than Significant Impact. Topsoil is used to cover surface areas for the establishment and maintenance of vegetation due to its high concentrations of organic matter and microorganisms. Little, if any, native topsoil is likely to occur on site since the site is covered with asphalt. During project construction, fill materials will be over-excavated to reveal underlying soils within the building footprint area. The project has the potential to expose surficial soils to wind and water erosion during construction activities. Wind erosion will be minimized through soil stabilization measures required by South Coast Air Quality Management District (SCAQMD) Rule 403 (Fugitive Dust), such as daily watering. Water erosion will be prevented through the City’s standard erosion control practices required pursuant to the California Building Code and the National Pollution Discharge Elimination System (NPDES), such as silt fencing or sandbags. Following project construction, the site would be covered completely by paving, structures, and landscaping. Impacts related to soil erosion would be less than significant with implementation of existing regulations. c) Less Than Significant Impact. Impacts related to liquefaction and landslides are discussed above in Section 4.6.a. Lateral spreading is the downslope movement of surface sediment due to liquefaction in a subsurface layer. The downslope movement is due to gravity and earthquake shaking combined. Such movement can occur on slope gradients of as little as one degree. Lateral spreading typically damages pipelines, utilities, bridges, and structures. Lateral spreading of the ground surface during a seismic activity usually occurs along the weak shear zones within a liquefiable soil layer and has been observed to generally take place toward a free face (i.e. retaining wall, slope, or channel) and to lesser extent on ground surfaces with a very gentle slope. Due to the absence of any substantial change in grade on the project site, the potential for lateral spread occurring is considered to be minimal. The project-specific geotechnical report concludes that site soils would be capable of supporting proposed structures after grading and compaction. The project is required to be constructed in accordance with the CBC, which specifies the removal of fill materials at least two feet below existing grade or planned pad grade, and at least one foot below the bottom of foundations and floor slab due to the presence of variable strength characteristics of the near surface onsite soils, so as to reduce any potential property damage from ground failure or soil instability. The CBC includes a requirement that any City-approved recommendations contained in the soil report be made conditions of the building permit. Based on the considerations of the project geotechnical report, soils can be prepared to maintain stability sufficient to support the proposed project. The recommendations of the geotechnical report will be implemented through the City’s routine plan check and permitting processes. Impact would be less than significant. Evaluation of Environmental Impacts Rossmoor Health Club 37 d) Less Than Significant Impact. The CBC requires special design considerations for foundations of structures built on soils with expansion indices greater than 20. The geotechnical report included testing of site soil samples within the proposed building footprint for expansion potential. The result of the geotechnical report expansion index soil sample test indicated that near surface sample soils had a low expansion potential. The CBC provides several options to mitigate and design for expansive soils. The geotechnical engineer for the project indicates that given the tested on-site soils’ low expansion potential, expansive soils could be addressed and any hazards removed by stabilization. Compliance with CBC requirements would limit hazards related to expansive soil to less than significant, and no mitigation is required. e) No Impact. The project site is served by a fully functional municipal sewer system. The project will connect to this system and would not require use of septic tanks. No impact would occur. Evaluation of Environmental Impacts 38 Initial Study 4.7 – Greenhouse Gas Emissions Potentially Significant Impact Less Than Significant with Mitigation Incorporation Less Than Significant Impact No Impact a) Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment? □ □ □ b) Conflict with an applicable plan, policy or regulation adopted for the purpose of reducing the emissions of greenhouse gases? □ □ □ a) Less Than Significant Impact. Climate change is the distinct change in measures of climate for a long period of time.17 Climate change is the result of numerous, cumulative sources of greenhouse gas emissions all over the world. Natural changes in climate can be caused by indirect processes such as changes in the Earth’s orbit around the Sun or direct changes within the climate system itself (i.e. changes in ocean circulation). Human activities can affect the atmosphere through emissions of greenhouse gases (GHG) and changes to the planet’s surface. Human activities that produce GHGs are the burning of fossil fuels (coal, oil and natural gas for heating and electricity, gasoline and diesel for transportation); methane from landfill wastes and raising livestock, deforestation activities; and some agricultural practices. Greenhouse gases differ from other emissions in that they contribute to the “greenhouse effect.” The greenhouse effect is a natural occurrence that helps regulate the temperature of the planet. The majority of radiation from the Sun hits the Earth’s surface and warms it. The surface in turn radiates heat back towards the atmosphere, known as infrared radiation. Gases and clouds in the atmosphere trap and prevent some of this heat from escaping back into space and re-radiate it in all directions. This process is essential to supporting life on Earth because it warms the planet by approximately 60° Fahrenheit. Emissions from human activities since the beginning of the industrial revolution (approximately 250 years ago) are adding to the natural greenhouse effect by increasing the gases in the atmosphere that trap heat, thereby contributing to an average increase in the Earth’s temperature. Greenhouse gases occur naturally and from human activities. Greenhouse gases produced by human activities include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6). Since 1750, it is estimated that the concentrations of carbon dioxide, methane, and nitrous oxide in the atmosphere have increased over 36 percent, 148 percent, and 18 percent, respectively, primarily due to human activity. Emissions of greenhouse gases affect the atmosphere directly by changing its chemical composition while changes to the land surface indirectly affect the atmosphere by changing the way the Earth absorbs gases from the atmosphere. 17 United States Environmental Protection Agency. Frequently Asked Questions About Global Warming and Climate Change. Back to Basics. April 2009. Evaluation of Environmental Impacts Rossmoor Health Club 39 GHG emissions for the project were quantified utilizing the California Emissions Estimator Model (CalEEMod) version 2013.2.2 to determine if the project could have a cumulatively considerable impact related to greenhouse gas emissions, and are summarized in Table 4 (Greenhouse Gas Emissions Inventory). The emissions inventory accounts for GHG emissions from construction activities and operational activities. Operation emissions associated with the proposed project would include GHG emissions from mobile sources (transportation), energy, water use and treatment, waste disposal, and area sources. GHG emissions from electricity use are indirect GHG emissions from the energy (purchased energy) that is produced offsite. Area sources are owned or controlled by the project (e.g., natural gas combustion, boilers, and furnaces) and produced onsite. Construction activities are short term and cease to emit greenhouse gases upon completion, unlike operational emissions that are continuous year after year until operation of the use ceases. Because of this difference, SCAQMD recommends amortizing construction emissions over a 30-year operational lifetime. This normalizes construction emissions so that they can be grouped with operational emissions in order to generate a precise project-based GHG inventory.

On December 5, 2008, the South Coast AQMD Governing Board adopted interim GHG significance thresholds. These thresholds were based on guidance provided in the CAPCOA CEQA and Climate Change white paper; thus, a non-zero threshold based on Approach 2 of the handbook will be used.18 Threshold 2.5 (Unit-Based Thresholds Based on Market Capture) establishes a numerical threshold based on capture of approximately 90 percent of emissions from future development. The latest threshold developed by SCAQMD using this method is 3,000 metric tons carbon dioxide equivalent (MTCO2E) per year for residential and commercial projects.19 This threshold is based on the review of 711 CEQA projects. 18 California Air Pollution Control Officers Association. CEQA and Climate Change. January 2008. 19 South Coast Air Quality Management District. CEQA Significance Thresholds Working Group. Meeting #15, Main Presentation. September 28, 2010. Evaluation of Environmental Impacts 40 Initial Study Pursuant to Section 15064.4 of the CEQA Guidelines, a lead agency has the discretion, in evaluating the significance of GHG emissions in the context of a particular project, to consider the “extent to which the project complies with regulations or requirements adopted to implement a statewide, regional, or local plan for the reduction or mitigation of greenhouse gas emissions.” Greenhouse gas emissions associated with the proposed project would not exceed the 3,000 MTCO2E threshold; therefore, impact would be less than significant. b) No Impact. Seal Beach has adopted the 2013 edition of the CBC (Title 24), including the California Green Building Standards Code. The project would be subject to the California Green Building Standards Code, which requires that new buildings reduce water consumption, employ building commissioning to increase building system efficiencies for large buildings, divert construction waste from landfills, and utilize low pollutant-emitting finish materials. The project does not include any feature (i.e. substantially alter energy demands) that would interfere with implementation of these state and City codes and plans. The City of Seal Beach does not have any additional plans, policies, standards, or regulations related to climate change and GHG emissions. Also, no other government-adopted plans or regulatory programs in effect at this time have established a specific performance standard to reduce GHG emissions from a single building project. No impact would occur. Evaluation of Environmental Impacts Rossmoor Health Club 41 4.8 – Hazards and Hazardous Materials Potentially Significant Impact Less Than Significant with Mitigation Incorporation Less Than Significant Impact No Impact a) Create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials? □ □ □ b) Create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment? □ □ □ c) Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school? □ □ □ d) Be located on a site which is included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5 and, as a result, would it create a significant hazard to the public or the environment? □ □ □ e) For a project located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project result in a safety hazard for people residing or working in the project area? □ □ □ f) For a project within the vicinity of a private airstrip, would the project result in a safety hazard for people residing or working in the project area? □ □ □ g) Impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan? □ □ □ Evaluation of Environmental Impacts 42 Initial Study Potentially Significant Impact Less Than Significant with Mitigation Incorporation Less Than Significant Impact No Impact h) Expose people or structures to a significant risk of loss, injury or death involving wildland fires, including where wildlands are adjacent to urbanized areas or where residences are intermixed with wildlands? □ □ □ a) Less Than Significant Impact. The proposed project could result in a significant hazard to the public if the project includes the routine transport, use, or disposal of hazardous materials or places housing near a facility which routinely transports, uses, or disposes of hazardous materials. The proposed project is located within a primarily commercial and residential area of the City, and is not located in an industrial area. The proposed project does not include a housing component and would therefore not place housing near any hazardous materials facilities. The routine use, transport, or disposal of hazardous materials is primarily associated with industrial uses that require such materials for manufacturing operations or produce hazardous wastes as by-products of production applications. The proposed project does not propose or facilitate any activity involving significant use, routine transport, or disposal of hazardous substances as part of health club use. During construction, there would be a minor level of transport, use, and disposal of hazardous materials and wastes that are typical of construction projects. This would include fuels and lubricants for construction machinery, coating materials, etc. Routine construction control measures and best management practices for hazardous materials storage, application, waste disposal, accident prevention and clean-up, etc. would be sufficient to reduce potential impacts to a less than significant level. With regard to project operation, widely used hazardous materials common at commercial uses such as health clubs include cleaners, pesticides, and pool chemicals. The remnants of these and other products are disposed of as household hazardous waste that are prohibited or discouraged from being disposed of at local landfills. Regular operation and cleaning of the health club would not result in significant impacts involving use, storage, transport or disposal of hazardous wastes and substances. Use of common household hazardous materials and their disposal does not present a substantial health risk to the community. Impacts associated with the routine transport and use of hazardous materials or wastes would be less than significant. b) Less than Significant Impact. The health club will include a pool. Operation of pools involves the use of potentially hazardous chemical (e.g., chlorine) for public health purposes. The storage of such materials onsite will be limited to amounts needed for routine maintenance, and all materials will be stored in conformance with the requirements of the Orange County Fire Authority. Compliance with existing regulations would reduce impact to a less-than-significant level. c) Less than Significant Impact. No schools are located within close proximity to the project site. The nearest schools are Rossmoor Elementary School, located approximately 3,000 feet north; Weaver Elementary School, located approximately 4,000 feet northwest; and Francis Hopkinson Elementary School, located approximately 4,000 feet southwest. Operation of the proposed project—a health club—would not generate any hazardous emissions, and the storage, Evaluation of Environmental Impacts Rossmoor Health Club 43 handling, production, or disposal of acutely hazardous materials is not required or proposed for any aspect of this project. As discussed above, use and storage of pool chemicals would occur in accordance with existing regulations. Impact would be less than significant with implementation of existing regulations. d) No Impact. The proposed project is not located on a site listed on the state’s Cortese List, a compilation of various sites throughout the state that have been compromised due to soil or groundwater contamination from past uses. Based upon review of the Cortese List, the project site is not:  listed as a hazardous waste and substance site by the Department of Toxic Substances Control (DTSC),20  listed as a leaking underground storage tank (LUFT) site by the State Water Resources Control Board (SWRCB),21  listed as a hazardous solid waste disposal site by the SWRCB,22  currently subject to a Cease and Desist Order (CDO) or a Cleanup and Abatement Order (CAO) as issued by the SWRCB,23 or  developed with a hazardous waste facility subject to corrective action by the DTSC.24 e-f) Less than Significant Impact. The Los Alamitos Joint Forces Training Base (JFTB) is a jointly operated military air base located at 11206 Lexington Drive, in the City of Los Alamitos. The westernmost boundary of the airfield is approximately 2,000 feet east of the proposed project site. The project site is located within the planning area for the air base. Los Alamitos JFTB includes two runways oriented in a southwest to northeast direction. Caltrans Airport Land Use Planning Handbook guidelines state that noise, obstruction of air navigation, and the safety of persons working or living in the area of the air base are the primary hazard-related concerns involving compatibility between the project and operations of the air base. Excessive noise could be damaging to the health of individuals working in or using the health club. Obstructions could occur due to tall structures within the approach and departure areas of an airport. Airport operations could also be impacted by smoke, glare, excessive lighting, and interference from electrical devices. These concerns are related to the potential for increase in aircraft crashes that can injure or kill persons on the ground, as well as the crew and passengers of involved aircraft. The potential from injury or death increases when the density of persons on the ground is increased. Potential impacts related to development of the proposed health club are discussed below. Airport Noise Noise is of concern if noise levels exceed a 24-hour average level referred to as CNEL (Community Noise Equivalent Level) and report in decibels (dB, or weighted decibels, dBA). According to the Caltrans Airport Land Use Planning Handbook, the basic guidance sets a CNEL of 20 California Department of Toxic Substances Control.

Evaluation of Environmental Impacts 44 Initial Study 65 dB as the maximum noise level normally compatible with urban residential land uses. The Impact Zone Map in the Airport Environs Land Use Plan (AELUP) for Los Alamitos JFTB depicts two noise contours: Noise Impact Zone 1 (greater than 65dBA, CNEL) and Noise Impact Zone 2 (between 60-65 dBA, CNEL). The proposed project site is located outside both the noise contours shown in the AELUP.25 As such, the proposed project is compatible with the AELUP noise policies. Impacts related to exposing people to excess airport noise would be less than significant. Obstruction of Air Navigation The Federal Aviation Administration (FAA), Federal Aviation Regulation (FAR) Part 77 is the primary reference source for determining obstructions to air navigation. FAR Part 77 establishes a series of imaginary surfaces in the airspace surrounding a runway or helicopter landing area. No object should penetrate into any of these surfaces to ensure an obstruction free airspace for pilots using the airport. The Caltrans Handbook and the Airport Land Use Plan Part 77 as a reference to define hazards to air navigation. Based on the project elevations (see Exhibit 4, Project Elevations), the most elevated point of the project would be 35 feet to the top of the decorative parapet. Other commercial/retail buildings located within the shopping center reach a height of 35 feet, which is the maximum allowable height for buildings located in General Commercial zones. Based on these observations, impacts related to the obstruction of Los Alamitos JFTB operations due to the height of the proposed building would be less than significant. Potential obstruction of airport operations is not limited to the height of structures; obstruction also includes light and glare effects, electromagnetic interference, and production of smoke. Beyond the height of the proposed building, illumination from interior lighting and proposed parking lot lights could also impact airport operations. Pursuant to the Seal Beach Zoning Code, all on-site lighting is required to be shielded and oriented so as to result in no light spillover onto adjacent properties (see Section 4.1 for further discussion). This would prevent lighting from potentially impacting approaching or departing aircraft because the light would not be substantially visible due to shielding and orientation. Lighting associated with the proposed project would result in less-than-significant impacts related to obstruction of airport operations with standard regulations implemented. As discussed in Section 4.1, glare impacts also would be reduced to less-than-significant levels with adherence to existing codes and standards. The proposed health club does not include any use that would produce unusual electronic frequencies or create and/or emit smoke. Safety The Los Alamitos JFTB AELUP divides the areas surrounding an airport into Clear Zones (CZ)/Runway Protection Zone (RPZ), Accident Potential Zone “I”, and Accident Potential Zone “II”. Clear Zones and Runway Protection Zones are designated as having the potential for extreme crash hazard. The severe potential for loss of life and property due to accidents prohibits most land uses in these areas. No buildings intended for human habitation are permitted in Clear Zones/Runway Protection Zones. The proposed project site is not located within any of the Clear Zones/Runway Protection Zones or either Accident Potential Zone “I” or Accident Potential Zone “II”, as shown in the Los Alamitos 25 Los Alamitos Joint Forces Training Base Airport Environs Land Use Plan. Impact Zones Map. December 19, 2002. Evaluation of Environmental Impacts Rossmoor Health Club 45 AELUP. 26 Furthermore, the project will not attract birds nor emit excessive glare or light, nor produce or cause steam, smoke, dust, or electronic interference that would interfere with or endanger, aeronautical operations at Los Alamitos JFTB. As such, the project would not present a safety hazard for persons in relation to airport-related accidents. Impacts would be less than significant. g) Less Than Significant Impact. The proposed project is an infill project, replacing 85,600 square feet of asphalt parking with an approximately 37,000-square-foot health club. As there are no residential uses associated with the project, the project would not increase the population of the area. Given the increase in built square footage on the site, the proposed project may increase employment in the area. Per state Fire and Building Codes, sufficient space would have to be provided around the building for emergency personnel and equipment access and emergency evacuation. All project elements, including landscaping, would be sited with sufficient clearance from existing and proposed structures so as not to interfere with emergency access to and evacuation from the facility. The project would comply with the California Fire Code (Title 24, California Code of Regulations, Section 9). The project driveways would allow emergency access and evacuation from the site, and would be constructed to California Fire Code specifications. Over the long term, the project would not impair implementation of or physically interfere with an adopted emergency response plan or evacuation plan because no permanent public street or lane closures are proposed. Construction work in the street associated with the building would be limited to lateral utility connections; which would be limited to nominal potential traffic diversion. Project impacts would be less than significant. h) No Impact. The project site is not located within a fire hazard zone, as identified on the latest Fire Hazard Severity Zone (FHSZ) maps prepared by the California Department of Forestry and Fire Protection (CALFIRE).27 There are no wildland conditions in the urbanized area that the project site is located. No impact would occur. 26 Los Alamitos Joint Forces Training Base Airport Environs Land Use Plan. Impact Zones Map. December 19, 2002. 27 California Department of Forestry and Fire Protection.

A project normally would have an impact on surface water quality if discharges associated with the project would create pollution, contamination, or nuisance as defined in Section 13050 of the California Water Code (CWC), or that cause regulatory standards to be violated as defined in the applicable National Pollutant Discharge Elimination System (NPDES) stormwater permit or Water Quality Control Plan for the receiving water body. For the purpose of this specific issue, a significant impact could occur if the project would discharge water that does not meet the quality standards of the agencies which regulate surface water quality and water discharge into stormwater drainage systems. Significant impacts could also occur if the project does not comply with all applicable regulations with regard to surface water quality as governed by the State Water Resources Control Board (SWRCB). These regulations include preparation of a Standard Urban Storm Water Mitigation Plan (SUSMP) to reduce potential post-construction water quality impacts. Discharges into stormwater drains or channels from construction sites of one acre or larger are regulated by the General Permit for Storm Water Discharges Associated with Construction Activity (General Permit: Water Quality Order 99-08-DWQ) issued by the State Water Quality Control Board in August 1999 and modified in April 2001. The General Permit was issued pursuant to National Pollutant Discharge Elimination System (NPDES) regulations of the Environmental Protection Agency (EPA), as authorized by the Clean Water Act. Compliance with the General Permit involves developing and implementing a Storm Water Pollution Prevention Plan (SWPPP) specifying best management practices (BMPs) that the project would use to minimize pollution of stormwater. The SWPPP BMPs would follow the guidelines set forth by the State Water Resources Control Board (SWRCB). The project applicant will be required to comply with NPDES permit requirements through the preparation and implementation of a SWPPP for construction activities. The City’s Public Works Director will review the application for compliance with applicable regulations and to ensure that no water quality standards or discharge requirements are violated. Evaluation of Environmental Impacts 48 Initial Study The project applicant has completed a Preliminary Water Quality Management Plan (WQMP). According to the WQMP, impervious surfaces will decrease as a result of project development. The percentage of pervious surfaces would increase from 6.1 percent to 7.4 percent of the site, and the percentage of impervious surfaces would decrease from 93.9 percent to 92.6 percent. The increase in pervious surface area and decrease in pervious surfaces would be attributed to the amount of pervious landscaping that is proposed as part of project development. Because the project would include pervious landscaped areas greater than current conditions, total runoff post-development would incrementally decrease discharge for onsite drainage for a 10-year design storm. Nonetheless, the WQMP includes recommendations for modular wetlands biofiltration devices and structural and non-structural source control BMPs that would be incorporated into project design. Per the geotechnical report, infiltration Best Management Practices (BMPs) were determined to be infeasible for the site. Structural source control BMPs would include efficient irrigation systems and landscape design, water conservation measures, smart controllers, and storm drain stenciling and signage. Non-structural source control BMPs would include education of property owners and tenants, certain activity restrictions, management of common area landscaping, Title 22 CCR compliance, common area litter control, employee training, common area catch basin inspection, street sweeping of private streets and parking lots, and implementation of a Spill Contingency Plan and the Uniform Fire Code. Plans for stormwater treatment are required to meet City and regional standards. With compliance with existing laws, and the implementation of the above mentioned water quality control measures, project impacts on water quality standards would be less than significant. b) Less Than Significant Impact. If the project removed an existing groundwater recharge area or substantially reduced runoff that results in groundwater recharge, a potentially significant impact could occur. According to the project WQMP, groundwater levels beneath the site are estimated to be 12 feet below the ground surface. Project-related grading would not reach these depths, and no disturbance of groundwater is anticipated. The proposed building footprint area and paved parking areas would not increase impervious surface coverage on the site; rather, impervious surfaces would be decreased through increased on-site landscaping. As such, the total amount of infiltration on site would be increased over existing conditions. Since this site is currently developed and is not managed for groundwater supplies, this change in infiltration would not have a significant effect on groundwater supplies or recharge. The project would be required to comply with Section 11.4.30 (Landscaping and Buffer Yards) of the City of Seal Beach Municipal Code, which would lessen the project’s demand for water resources. Also, CBC Title 24 water efficiency measures require a demonstrated 20 percent reduction in the use of potable water. The project’s landscaping plans include drought-tolerant landscaping materials. Compliance with Title 24 and the City’s Water Conservation in Landscaping and Water Efficient Landscaping Ordinances would reduce the proposed project’s impacts to groundwater supplies to a level of less than significant. Water supply is further discussed in Checklist Response 3.17d. c) Less Than Significant Impact. Potentially significant impacts to the existing drainage pattern of the site or area could occur if development of the project results in substantial on- or off-site erosion or siltation. No streams cross the project site; thus, the project would not alter any stream course. As discussed in Section 4.9.a above, the project would include facilities to treat stormwater flows on site through modular wetland biofiltration and a number of structural and non-structural source control MBPs before runoff enters going to the municipal storm drain Evaluation of Environmental Impacts Rossmoor Health Club 49 system. A site drainage plan is required by the City of Seal Beach and would be reviewed by the City Engineer. The final grading and drainage plan will be approved by the City Engineer during plan check review. Erosion and siltation reduction measures would be implemented during construction consistent with an approved SWPPP, which will demonstrate compliance with the City’s NPDES permit. At the completion of construction, the project would consist of impervious surfaces and landscaped areas, and would therefore not be prone to substantial erosion. No streams cross the project site; thus, the project would not alter any stream course. Impact would be less than significant. d-e) Less Than Significant Impact. No streams traverse the project site; thus, the project would not result in the alteration of any stream course. During construction, the project applicant would be required to develop and implement a SWPPP as required by law; this would prevent polluted runoff from leaving the construction site. With regard to project operation, on-site drainage would be directed to modular wetland biofiltration treatment systems before discharging into street drains. Construction of the proposed project would not increase the net area of impermeable surfaces on the site; in fact, the project would increase permeable areas and infiltration; therefore, substantially increased discharges to the City’s existing storm drain system will not occur and will not impact local storm drain capacity. The project is not an industrial use and therefore will not result in substantial pollutant loading such that treatment control BMPs would be required to protect downstream water quality. Impacts would be less than significant. f)No Impact. The project does not propose any uses that would have the potential to otherwise degrade water quality beyond those issues discussed in Section 4.9. g)No Impact. The project does not propose any housing; therefore, no impact would occur. h)No Impact. The proposed project is not located within a 100-year floodplain, as mapped by the Federal Emergency Management Agency (FEMA) Flood Insurance Rate Maps. The project site is identified as Zone X, defined by FEMA as areas outside the 0.2 percent annual chance floodplain. 28 Therefore, no rising of a floodplain would occur. i)No Impact. According to the City of Seal Beach General Plan Safety Element, the project site is not located within an inundation area of a dam.29 Thus, the project is not anticipated to result in the exposure of persons or structures to risk of hazards associated with dam inundation. No impact would occur. j)No Impact. The proposed project is located less than a mile from the Pacific Ocean. However, according to the Seal Beach General Plan Safety Element, seismically induced seiches (that is, the sloshing of water due to an earthquake) are not considered a potential hazard in the City. Moreover, the tsunami hazard in the City is considered low for elevations above the principal sea bluff in Seal Beach. Areas on the beach or below the sea bluff are considered to have a moderate tsunami hazard, depending on tidal conditions and their elevation with respect to sea level. The proposed project site is located in a completely urbanized area of the City, approximately 16 feet above sea level. Impacts related to seiche and tsunami are not expected to occur. 28 Federal Emergency Management Agency. Flood Insurance Rate Map. Map Number 06059C0112J. December 3, 2009. 29 City of Seal Beach.

Evaluation of Environmental Impacts 50 Initial Study 4.10 – Land Use and Planning Would the project: Potentially Significant Impact Less Than Significant with Mitigation Incorporation Less Than Significant Impact No Impact a) Physically divide an established community? □ □ □ b) Conflict with any applicable land use plan, policy, or regulation of an agency with jurisdiction over the project (including, but not limited to the general plan, specific plan, local coastal program, or zoning ordinance) adopted for the purpose of avoiding or mitigating an environmental effect? □ □ □ c) Conflict with any applicable habitat conservation plan or natural community conservation plan? □ □ □ a) No Impact. The proposed project site is located on the edge of an existing shopping center, The Shops at Rossmoor and adjacent to a condominium complex to the north, separated from The Shops at Rossmoor by a block wall. The proposed project would replace asphalt parking with a health club. The proposed project is consistent and compatible with surrounding land uses within the shopping center and will not divide an established community. The project does not propose construction of any roadway, flood control channel, or other structure that would physically divide any portion of the community. Therefore, no impact would occur. b) No Impact. The project site is designated as General Commercial in the Seal Beach General Plan. The project site is zoned General Commercial (GC). The General Commercial land use category accommodates highway-oriented commercial uses. The GC zone allows a range of retail sales and service uses by right, such as those occupying The Shops at Rossmoor center. Large-scale commercial recreation uses, such as the proposed health club project, as permitted subject to approval of a Conditional Use Permit. The proposed project is consistent with both General Plan policy and zoning regulations. No impact would occur. c) No Impact. As discussed in Checklist Response 4.4.f above, the proposed project site and surrounding areas are not part of any habitat conservation plan, natural community conservation plan, or other approved local, regional, or state habitat conservation plan. As such, no impact would occur.

The project site, located within a fully urbanized area of the City of Seal Beach, is surrounded by commercial and residential uses. No mineral resource areas exist in the immediate vicinity.30 Development would not result in the loss of a known mineral resource. No impact would occur. 30 City of Seal Beach.

Also, groundbourne vibrations were analyzed using criteria established by Caltrans since the City does not have any thresholds for assessing vibration impacts. Evaluation of Environmental Impacts Rossmoor Health Club 53 Noise can be defined as unwanted sound. Sound (and therefore noise) consists of energy waves that people receive and interpret. Sound pressure levels are described in logarithmic units of ratios of sound pressures to a reference pressure, squared. These units are called bels. In order to provide a finer description of sound, a bel is subdivided into 10 decibels, abbreviated dB. To account for the range of sound that human hearing perceives, a modified scale is utilized known as the A-weighted decibel (dBA). Since decibels are logarithmic units, sound pressure levels cannot be added or subtracted by ordinary arithmetic means. For example, if one automobile produces a sound pressure level of 70 dBA when it passes an observer, two cars passing simultaneously would not produce 140 dBA. In fact, they would combine to produce 73 dBA. This same principle can be applied to other traffic quantities as well. In other words, doubling the traffic volume on a street or the speed of the traffic will increase the traffic noise level by 3 dBA. Conversely, halving the traffic volume or speed will reduce the traffic noise level by 3 dBA. A 3 dBA change in sound is the beginning at which humans generally notice a barely perceptible change in sound and a 5 dBA change is generally readily perceptible.31 Noise consists of pitch, loudness, and duration; therefore, a variety of methods for measuring noise has been developed. According to the California General Plan Guidelines for Noise Elements, the following are common metrics for measuring noise:32 LEQ (Equivalent Energy Noise Level): The sound level corresponding to a steady-state sound level containing the same total energy as a time-varying signal over given sample periods. LEQ is typically computed over 1-, 8-, and 24-hour sample periods. CNEL (Community Noise Equivalent Level): The average equivalent A-weighted sound level during a 24-hour day, obtained after addition of five decibels to sound levels in the evening from 7:00pm to 10:00pm and after addition of ten decibels to sound levels in the night from 10:00pm to 7:00am. LDN (Day-Night Average Level): The average equivalent A-weighted sound level during a 24- hour day, obtained after the addition of ten decibels to sound levels in the night after 10:00pm and before 7:00am. CNEL and LDN are utilized for describing ambient noise levels because they account for all noise sources over an extended period of time and account for the heightened sensitivity of people to noise during the night. LEQ is better utilized for describing specific and consistent sources because of the shorter reference period. a) Less Than Significant Impact. The City of Seal Beach General Plan Noise Element establishes noise/land use compatibility criteria, and Municipal Code Chapter 7.15 (Noise) sets forth noise regulations by land use.33 General Plan noise policy does not directly address uses such as the proposed health club, but the use can be considered analogous to an outdoor recreation facility, which can be considered compatible in environments where the exterior noise level is up to 70-75 Ldn or CNEL. 31 California Department of Transportation. Basics of Highway Noise: Technical Noise Supplement. November 2009. 32 California Governor’s Office of Planning and Research. General Plan Guidelines. 2003. 33 City of Seal Beach Municipal Code. Chapter 7.15 (Noise). Evaluation of Environmental Impacts 54 Initial Study With regard noise ordinance regulations applied to commercial uses such as the proposed health club, the use can generate a maximum exterior noise level of 65 dBA CNEL during all hours of the day (with noise spikes permitted of short duration). Existing land uses surrounding the project site and within the project vicinity generally consists of commercial and residential land uses. The project site is located within an existing 70 dBA CNEL noise contour for roadway and freeway noise; however, this noise level is within the “normally acceptable” level for commercial uses as denoted in the City’s Code of Ordinances. The proposed project will not result in any new uses or traffic generation that would increase noise levels in the vicinity or expose persons to levels above those that are deemed normally acceptable in the noise ordinance. Impact would be less than significant. b) Less Than Significant Impact. A significant impact would occur if project construction or operation results in exposure of persons to or generation of excessive groundborne vibration or groundborne noise levels. Vibration is the movement of mass over time. It is described in terms of frequency and amplitude and unlike sound; there is no standard way of measuring and reporting amplitude. Vibration can be described in units of velocity (inches per second) or discussed in decibel (dB) units in order to compress the range of numbers required to describe vibration. Vibration impacts to buildings are generally discussed in terms of peak particle velocity (PPV) that describes particle movement over time (in terms of physical displacement of mass). For purposes of this analysis, PPV will be used to describe all vibration for ease of reading and comparison. The primary concern related to vibration and people is the potential to annoy those working and residing in the area. Vibration with high enough amplitudes can damage structures (such as crack plaster or destroy windows). Groundborne vibration can also disrupt the use of sensitive medical and scientific instruments such as electron microscopes. Common sources of vibration within communities include construction activities and railroads. Operation of the proposed health club does not include uses that cause vibration, and there are no railroads located in close proximity to the project site. Construction Impacts The proposed project site is adjacent to a residential condominium development. Potential concerns during project construction include groundborne vibrations. Groundborne vibration generated by construction projects is usually highest during pile driving, rock blasting, soil compacting, jack hammering, and demolition-related activities. Next to pile driving, grading activity has the greatest potential for vibration impacts if large bulldozers, large trucks, or other heavy equipment are used. According to the Caltrans vibration manual, large bulldozers, vibratory rollers (used to compact earth), and loaded trucks utilized during grading activities can produce vibration, and depending on the level of vibration, could cause annoyance at uses within the project vicinity or can damage structures. Caltrans has developed a screening tool to determine of vibration from construction equipment is substantial enough to impact surrounding uses. The Caltrans vibration manual establishes thresholds for vibration impacts on buildings and humans. These thresholds are summarized in Tables 5 (Vibration Damage Potential Threshold Criteria) and 6 (Vibration Annoyance Potential Threshold Criteria). Evaluation of Environmental Impacts Rossmoor Health Club 55 Table 5 Vibration Damage Potential Threshold Criteria Structural Integrity Maximum PPV (in/sec) Transient Continuous Extremely fragile historic buildings, ruins, ancient monuments 0.12 0.08 Fragile buildings 0.20 0.10 Historic and some older buildings 0.50 0.25 Older residential structures 0.50 0.30 New residential structures 1.00 0.50 Modern industrial and commercial structures 2.00 0.50 Source: Caltrans 2004 Table 6 Vibration Annoyance Potential Threshold Criteria Human Response PPV Threshold (in/sec) Transient Continuous Barely perceptible 0.04 0.01 Distinctly perceptible 0.25 0.04 Strongly perceptible 0.90 0.10 Severely perceptible 2.00 0.40 Source: Caltrans 2004 As noted above, Seal Beach does not have any regulations pertaining to vibration. However, the City does regulate construction noise (see Municipal Code Section 7.15.025, Exemptions), limiting construction, repair, remodeling, or grading of any real property to between the hours of 7:00 A.M. and 8:00 P.M. on weekdays, and 8:00 A.M. and 8:00 P.M. on Saturdays. Construction activities are not permitted on Sundays. Construction activities that use vibratory rollers and bulldozers are repetitive sources of vibration; therefore, the continuous threshold above has been used to assess potential impact on the adjacent residential development. Given the age of the development, the older residential structures threshold was used. Based on the threshold criteria summarized in Tables 5 and 6, vibration from use of heavy construction equipment for the proposed project would be below the thresholds to cause damage to nearby structures and result in less than barely perceptible vibration at the four receptors shown in Table 7 (Distance to Vibration Receptors) and Table 8 (Construction Vibration Impacts). Impact would be less than significant impact. Also, the requirements in the Municipal Code related to noise would limit the hours of construction as noted above.

The proposed project has the potential to increase ambient noise levels associated with activity on the site and increased traffic generation in the project vicinity. Below is a discussion of the existing noise environment on the site, followed by a discussion of noise measurements and operational noise that can be expected from the proposed project. Existing Noise Environment The proposed project site is currently used as parking for retail development within the Shops at Rossmoor. However, residents of the condominiums to the west and apartments to the north also use the parking lot without authorization. As such, the project site currently experiences frequent automobile arrivals and departures associated with use of the retail shops and residential developments adjoining the site. While arrivals and departures associated with the retail uses occur during the posted store operating hours, arrivals and departures associated with adjoining residential uses occur throughout the day and night, as observed during site visits. The project site is also located on the rear/service side of existing retail stores to the east, meaning truck trailer loading docks are located in this area. As such, this area experiences sporadic semi-truck deliveries during the daytime store operating hours, as observed during site visits. Truck trailer deliveries create temporary noise spikes with opening of trailer gates, extending of delivery ramps, and cold starting of diesel engines. Noise Measurements The above-mentioned activities were recorded via a noise-measuring device on Wednesday, April 1, 2015. Measurements were taken during two separate periods of the day. Two 15-minute measurements were taken during each of the measurement periods, for a total of four readings. The first set of measurements was taken during the A.M. peak hour and the second set of measurements during the 9:00-10:00 P.M. hour. The morning peak time was chosen because the health club would be open before the retail shops on weeknights; the later time was chosen because the health club would close after the retail shops close on weeknights. As such, operation of the proposed project would take place outside the current operating times of existing retail developments in the shopping center. Evaluation of Environmental Impacts Rossmoor Health Club 57 During the morning peak hour measurement period, a maximum LEQ of 54.7 was recorded, and during the nighttime measurement period a maximum LEQ of 49.9 was recorded. Both noise levels call within the established thresholds in the City’s noise ordinance. It should be noted that during the morning measurement time, truck trailer deliveries were observed at the loading docks, while no truck trailer deliveries took place during the nighttime measurements. Operation of the proposed project would produce noise associated with such activities as vehicle traffic, loud conversations, opening and closing of car doors, periodic landscape maintenance, etc. However, these noise sources are typical of commercial/retail uses and are not expected to induce a substantial permanent increase in ambient noise levels in the project vicinity above levels existing without the project. These noise sources would not exceed standards established in the local noise ordinance. Moreover, the proposed health club would not double traffic on either Seal Beach Boulevard or Rossmoor Center Way and therefore would not result in an ambient increase in traffic-related noise by 3 dBA or more 34. Thus, operation of the proposed health club and associated traffic-related noise would not create noise increases that would be perceptible to the surrounding community. Impact would be less than significant. d) Less than Significant Impact with Mitigation Incorporated. The project would have associated temporary construction-related noise increases due to on-site ground disturbing and construction activities. Construction noise levels vary depending on the type and intensity of construction activity, equipment type and duration of use, and the distance between the noise sources and the receiver. Typical sound emission characteristics of construction equipment are provided in Exhibit 5 (Construction Equipment Noise). Construction noise levels were estimated using the FHWA Roadway Construction Noise Model (RCNM) (see Appendix A, Roadway Construction Noise Modeling Data). Temporary noise increases would be greatest during demolition activities when jackhammers and small bulldozers can produce noise levels up to 88.9 dBA at 233 feet (at the adjacent condominium development) from the equipment source. This noise level exceeds the noise ordinance ambient standard for residential areas. 34 LSA Associates, Inc. Traffic Analysis. Health Club Within the Shops at Rossmoor. March, 2015. Evaluation of Environmental Impacts 58 Initial Study Exhibit 5 Construction Equipment Noise Evaluation of Environmental Impacts Rossmoor Health Club 59 As described above, for residential areas the City’s noise ordinance establishes an ambient exterior noise standard of 55 dbA between 7:00 A.M. and 10:00 P.M. and 50 dBA between 10:00 P.M. and 7:00 A.M. Construction noise in excess of noise standards is permitted between the hours of 7:00 A.M. and 8:00 P.M. on weekdays, and 8:00 A.M. and 8:00 P.M. on Saturdays. Construction activities are not permitted on Sundays. Compliance with these requirements would reduce construction noise impacts on the surrounding residential uses. However, to further reduce construction noise impacts on nearby receptors, Mitigation Measure NOI-1 and NOI-2 would be applied to the project if approved. Temporary construction-related noise impacts would be less than significant with implementation of existing performance standards. Mitigation Measure NOI-1: The contractor shall limit construction activities to between the hours of 7:00 A.M. and 7:00 P.M. on weekdays, and 8:00 A.M. and 6:00 P.M. on Saturdays. Construction activities will not be permitted on Sundays or any federal holidays. Mitigation Measure NOI-2: The contractor, to the satisfaction of the Community Development Director, shall provide for all construction vehicles to have mufflers and be maintained in good operating order at all times. No major vehicle repair shall be conducted on the site. e,f) No Impact. Impacts related to excessive noise levels from Los Alamitos JFTB are discussed in Section 4.8, Hazards and Hazardous Materials. As indicated, the proposed project site is located outside both the noise contours shown in the AELUP for the air base.35 As such, the proposed project would be compatible with the AELUP noise policies and would not expose persons residing or working in the project vicinity to excessive aircraft-related noise levels. Impacts related to exposing people to excess airport noise would be less than significant. 35 Los Alamitos Joint Forces Training Base Airport Environs Land Use Plan. Impact Zones Map.

Evaluation of Environmental Impacts 60 Initial Study 4.13 – Population and Housing Would the project: Potentially Significant Impact Less Than Significant with Mitigation Incorporation Less Than Significant Impact No Impact a) Induce substantial population growth in an area, either directly (for example, by proposing new homes and businesses) or indirectly (for example, through extension of roads or other infrastructure)? □ □ □ b) Displace substantial numbers of existing housing, necessitating the construction of replacement housing elsewhere? □ □ □ c) Displace substantial numbers of people, necessitating the construction of replacement housing elsewhere? □ □ □ a) Less Than Significant Impact. The proposed project does not include any residential uses; therefore, this project could not result in any direct residential growth. No new expanded infrastructure is proposed that could accommodate additional growth in the area that is not already possible with existing infrastructure, so no indirect population growth would occur. The project would bring a new business to the area. The applicant anticipates up to 45 employees in the new health club, with approximately 15 employees on site for any single shift. According to the Southern California Association of Governments (SCAG), employment in the City is projected to increase by 1,200 jobs between 2008 and 2035.36 Project employment for the project is within the employment growth assumptions for Seal Beach. Due to the urban nature of the City and surrounding area, this potential minimal increase in the employment population is expected to be accommodated by existing housing in the City and neighboring communities. Impacts would be less than significant. b) No Impact. The project site is currently an asphalt parking that will be partially demolished to facilitate project construction. The project site does not contain any housing units and does not require removal of any residential units; no impact would occur. c) No Impact. Displacement, in the context of housing, can generally be defined as persons or groups of persons who have been forced or obliged to flee or to leave their homes or places of habitual residence.37 There is no housing located onsite and therefore no residents. As such, the project would not result in forced or obliged removal of persons. No impact would occur. 36 Southern California Association of Governments.

Evaluation of Environmental Impacts Rossmoor Health Club 61 4.14 – Public Services Would the project result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times or other performance objectives for any of the public services: Potentially Significant Impact Less Than Significant with Mitigation Incorporation Less Than Significant Impact No Impact a) Fire protection? □ □ □ b) Police protection? □ □ □ c) Schools? □ □ □ d) Parks? □ □ □ e) Other public facilities? □ □ □ a) Less Than Significant Impact. The Orange County Fire Authority (OCFA) provides fire protection and emergency medical response services to the City of Seal Beach. OCFA also provides prevention services (e.g., inspections, permits, and drills) within its jurisdiction. OCFA has mutual aid agreements with other jurisdictions and practices unified command in response to potential emergencies. The project site is served by OCFA Fire Station No. 48, which is located 0.8 miles south of the project site. Fire Station No. 48, located at 3131 North Gate Road in Seal Beach, is staffed with a four-person quint (combination engine/ladder truck apparatus) and a two-person paramedic squad. In 2009, Fire Station No. 48 received 5,956 calls.38 Use of fire protection services for the proposed project is expected to be similar to other commercial activities in the area. No new or expanded fire protection facilities would be required as a result of this project. Furthermore, the proposed health club does not propose to use hazardous materials or engage in hazardous activities that would require new or modified fire protection equipment to meet potential emergency demand. Impacts related to expansion of fire protection services would be less than significant. b) Less Than Significant Impact. The Seal Beach Police Department (SBPD), headquartered at 911 Seal Beach Boulevard, provides police protection to the City, including the project site. The SBPD covers a service area of approximately 13 square miles and a population of 24,605. SBPD 38 Orange County Fire Authority Website. OCFA Fire Stations Details: Station No. 48. http://www.ocfa.org/Menu/Departments/Operations/PopUps/stn48.htm [Accessed March, 2015]. Evaluation of Environmental Impacts 62 Initial Study has 40 sworn police officers, or a ratio of .615 police officers for every 1,000 persons. SBPD also has 24 civilian staff.39 The proposed health club is a commercial business that would not create any unique crime problems than any other similar operation; such activities can be handled with the existing level of police resources. Private security is currently provided for the shopping center, as observed during site visits. No new or expanded police facilities would need to be constructed as a result of this project. No substantial increase in crime is expected with development of the proposed project. Impacts on police protection services would be less than significant. c) Less Than Significant Impact. As a commercial land use, this project would not have any residential population and would not generate any direct demand for school facilities. However, the project could have an indirect impact by attracting employees to the area with school-age children. Pursuant to the Leroy F. Green School Facilities Act (AB 2926), as adopted in California Education Code Section 17070.10-17070.99, the project proponent would be required to pay developer fees to the Los Alamitos Unified School District, prior to the issuance of building permits, at the current rate charged to commercial development projects. This fee would help support provision of school services for the community as a whole. According to AB 2926, payment of developer fees constitutes adequate mitigation for any project-related impacts to school facilities. Impact to school facilities would be less than significant. d) Less Than Significant Impact. Demand for park and recreational facilities generally are the direct result of residential development. However, as indicated above, no residential dwelling units are proposed as part of this project. Also, the project would not substantially contribute a new employment base to the City that could impact demand for public parks (see Section 14.3). As a result, no substantial demand for park and recreation facilities would result. Furthermore, the project primary purpose is to provide onsite activities where patrons participate in recreation/fitness exercises within the proposed structure. Impact would be less than significant. e) No Impact. The proposed project, a nonresidential use, would not result in any population growth that would require expansion of any other public services such as libraries or hospitals. The proposed health club would not rely on any such services to conduct normal business operations. No impact would occur. 39 City of Seal Beach. Seal Beach Police Department Website. http://www.sealbeachca.gov/safety/police/organization/ [Accessed March, 2015]. Evaluation of Environmental Impacts Rossmoor Health Club 63 4.15 – Recreation Potentially Significant Impact Less Than Significant with Mitigation Incorporation Less Than Significant Impact No Impact a) Would the project increase the use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated? □ □ □ b) Does the project include recreational facilities or require the construction or expansion of recreational facilities which might have an adverse physical effect on the environment? □ □ □ a) No Impact. The proposed health club project would not increase use of existing recreational facilities because employees, patrons, and vendors are not expected to combine a trip to a local park with a trip to this health club. All fitness/recreational activities associated with this use are programmed to occur within the building. Therefore, no impact would occur. b) No Impact. The project does not include outdoor recreational facilities and does not necessitate expansion of existing outdoor recreational facilities. The proposed project is a 37,000- square-foot health club where patrons pay a membership fee to participate in recreation/fitness exercises within the proposed structure. Therefore, no adverse physical effect on the environment caused by expansion or construction of outdoor recreational facilities would occur.

A project-specific traffic/circulation and parking analysis, authored by LSA Associates Inc., dated October, 2015 (see Appendices B and C, Traffic and Queuing Analysis and Traffic Impact Analysis), was prepared to assess project traffic and parking impacts. The analysis was prepared consistent with the City Traffic Impact Study Guidelines (March 2010) and the City’s General Plan (December 2012).40 The Shops at Rossmoor retail/commercial center west of Seal Beach Boulevard recently underwent modifications and changes at several locations and is close to full occupancy, with one unoccupied retail space of 2,400 square feet. Existing traffic along Seal Beach Boulevard includes the traffic from the occupied retail spaces within The Shops at Rossmoor, as well as residential traffic from the Rossmoor community. To analyze traffic conditions along Seal Beach Boulevard when The Shops at Rossmoor is fully occupied, traffic for the unoccupied retail space was added to the existing traffic volumes. The study analyzes the weekday morning, evening, and weekend mid-day peak hour levels of service (LOS) at 15 study area intersections and 11 roadway segments for the following scenarios: 1. Existing (2014) conditions with current occupancy of the retail center 2. Existing (2014) conditions with estimated full occupancy of the retail center 3. Existing (2014) conditions with estimated full occupancy of the retail center plus the proposed health club 4.

Seal Beach Boulevard is a six-lane Major Arterial per the City’s General Plan, which provides connection to the I-405 freeway as well as the Interstate 605 (I-605) freeway (via Katella Avenue). The 1.2-mile section of Seal Beach Boulevard between I-405 and Bradbury Road provides connection to commercial uses both east and west of Seal Beach Boulevard via local collector streets. There are retail/commercial uses on either side of Seal Beach Boulevard between St. Cloud Drive and Bradbury Road. The existing traffic along Seal Beach Boulevard includes traffic from the occupied retail space within the Shops at Rossmoor, as well as residential traffic from the Rossmoor community.

The HCM 2000 unsignalized intersection methodology presents LOS in terms of control delay (in seconds per vehicle). The resulting delay is expressed in terms of LOS, as in the ICU methodology. The relationship of delay to LOS is demonstrated in Table 11 (ICU Methodology Significance Thresholds). Table 11 ICU Methodology Significance Thresholds LOS Unsignalized Intersection Delay (seconds) A ≤10.0 B >10.0 and ≤15.0 C >15.0 and ≤25.0 D >25.0 and ≤35.0 E >35.0 and ≤50.0 F >50.0 ICU = Intersection Capacity Utilization LOS = level of service Evaluation of Environmental Impacts 68 Initial Study Roadway segments have uniform traffic conditions and roadway characteristics. The measure used to provide an estimate of LOS is density, where density is calculated from the average vehicle flow rate per lane and the average speed. Table 12 (Level of Service and Flow Density) shows the correlation between LOS and flow density. Table 12 Level of Service and Flow Density LOS Density (pc/mi/ln) A ≤11 B >11-18 C >18-26 D >26-35 E >35-45 F >45 LOS = level of service pc/mi/ln = passenger cars per mile per lane For the purposes of this project, the analysis considered LOS D as satisfactory on all study area roadway segments. Existing Conditions Existing weekday morning (7:00 A.M.– 9:00 A.M.), evening (4:00 P.M.– 6:00 P.M.), and weekend mid-day (11:00 A.M.– 1:00 P.M.) peak-hour traffic conditions and LOS were analyzed for existing (2014) conditions. Intersection turn-movement counts were made at the 15 study area intersections, and daily 24-hour counts were conducted for the 11 study area roadway segments. The trips generated from surrounding existing land uses, which consist of residential and retail uses east and west of Seal Beach Boulevard, are included in the counts. A summary of Existing (2014) Levels of Service for intersections and roadway segments are presented in Tables 13 (Existing 2014 Peak Hour Intersection Level of Service Summary) and 14 (Existing 2014 Peak Hour Roadway Level of Service Summary), respectively.

The unoccupied portion of the Shops at Rossmoor consists of 2,400 sf of retail use and is located between Pure Barre and Chick-fil-A just west of Seal Beach Boulevard. Trip generation for the unoccupied space was calculated based on rates contained in the Institute of Transportation Engineers’ (ITE) Trip Generation (Ninth Edition), which is a standard reference used by jurisdictions throughout the country for estimating the trip generation potential of new developments. The unoccupied space is classified as part of the shopping center use (ITE Land Use 820). The potential trip generation was calculated using the average rates (per 1,000 sf) as opposed to the fitted curve equation as the equations are inappropriate for the size of the unoccupied space and would result in an unrealistic estimation of potential trips. As indicated in Table 16 (Unoccupied Evaluation of Environmental Impacts 70 Initial Study Space within the Shops at Rossmoor Trip Generation), the unoccupied space is estimated to generate 102 daily trips, 2 weekday a.m. peak hour trips, 9 weekday p.m. peak hour trips, and 12 Saturday mid-day peak hour trips.

ADT = average daily traffic TSF = thousand square feet The new retail trips were distributed throughout the study area using the same information from the County’s current travel demand model (Orange County Transportation Analysis Model [OCTAM]) that was utilized for the proposed project. Trips generated by the unoccupied parcel were added to the base traffic volumes to develop “with Full Occupancy” traffic volumes. Existing (2014) with Full Occupancy Conditions To represent the full potential of traffic that could traverse Seal Beach Boulevard and the study area in the existing condition, existing weekday a.m., p.m. and weekend mid-day peak-hour traffic conditions were modified based on the additional traffic from the unoccupied space for the Existing (2014) with Full Occupancy scenario. The trip assignment of the unoccupied portion of the retail center was added to the Existing (2014) counts to develop the volumes for the Existing (2014) with Full Occupancy conditions. A summary of Existing (2014) with Full Occupancy conditions LOS at study area intersections and roadway segments are presented in Tables 17 (Existing 2014 with Full Occupancy Peak Hour Intersection Level of Service Summary) and 18 (Existing 2014 with Full Occupancy Peak Hour Roadway Level of Service Summary), respectively. As the tables indicate, all study area intersections and roadway segments are anticipated to operate at satisfactory LOS (LOS D or better). Less than significant impacts will occur.

Project Completion Year (2016) with Full Occupancy Conditions According to the project applicant, the proposed project will be completed in 2016. In order to present a near-term 2016 traffic condition, an ambient growth rate of 0.5 percent per year was added to existing traffic volumes along with traffic from the unoccupied parcel within The Shops at Rossmoor. This growth rate was reached through consultation with City staff. It should be noted that City staff also provided information on one nearby cumulative development of a new car wash within the Mobil gas station on the northeast corner of Seal Beach Boulevard and Rossmoor Center Way/Plymouth Drive. Additional traffic from this development was not included in the analysis as the traffic counts taken in November 2014 have taken into account the existing car wash within the Mobil gas station. A summary of Project Completion Year (2016) with Full Occupancy LOS for study area intersections and roadway segments is presented in Tables 21 (Project Completion Year 2016 with Full Occupancy Peak Hour Intersection Level of Service Summary) and 22 (Project Completion Year 2016 with Full Occupancy Peak Hour Roadway Level of Service Summary), respectively.

Evaluation of Environmental Impacts Rossmoor Health Club 75 Future (2035) General Plan Buildout Conditions Traffic conditions for the future long-range condition, corresponding to the buildout of the City’s General Plan, were analyzed in the study. The traffic volumes for Future (2035) General Plan Buildout traffic conditions were developed based on an annual growth rate applied to the Existing (2014) weekday a.m., p.m., and weekend peak-hour traffic volumes at study intersections and roadway segments to represent a 21-year horizon. To develop the Future (2035) General Plan Buildout baseline volumes, LSA estimated the annual growth rate of 0.2 percent per year based on the growth along Seal Beach Boulevard using the OCTAM traffic model. However, based on discussions with City staff, a growth rate of 0.5 percent per year was applied over the next 21 years to provide a conservative traffic analysis. To account for the fully occupied retail center, the trip assignment generated earlier for the unoccupied portion was manually added to the Future (2035) General Plan Buildout traffic volumes to develop the volumes for the Future (2035) General Plan Buildout with Full Occupancy condition. The LOS at the study area intersections and roadway segments were identified based on this data. A summary of Future (2035) General Plan Buildout with Full Occupancy LOS for study area intersections and roadway segments is presented in Tables 25 (Future 2035 General Plan Buildout with Full Occupancy Peak Hour Intersection Level of Service Summary) and 26 (Future 2035 General Plan Buildout with Full Occupancy Peak Hour Roadway Level of Service Summary), respectively. The LOS for study area intersections and roadway segments associated with the inclusion of the proposed project are presented in Tables 27 (Future 2035 General Plan Buildout with Full Occupancy Plus Health Club Peak Hour Intersection Level of Service Summary) and 28 (Future 2035 General Plan Buildout with Full Occupancy Plus Health Club Peak Hour Roadway Level of Service Summary), respectively. As shown on the tables, all study area intersections and roadway segments are anticipated to operate at satisfactory LOS (LOS D or better) under Future (2035) General Plan Buildout with Full Occupancy, without and with health club conditions. Impacts related to level of service for project intersections and roadways will be less than significant. As shown on Table 27, the addition of project traffic at the intersection of Seal Beach Boulevard and Rossmoor Center Way results in an ICU increase that exceeds the City’s threshold of significance by 0.004 during the weekday p.m. peak hour. It should be noted this intersection is anticipated to operate at an acceptable LOS C or better under all peak hours in the Future (2035) General Plan Buildout with Full Occupancy with Health Club conditions. As all study area intersections and roadway facilities are anticipated to operate at satisfactory LOS from Existing (2014) to Future (2035) General Plan Buildout with Full Occupancy plus Health Club traffic conditions, operational improvements aimed at alleviating LOS deficiencies are not warranted and have not been recommended. However, the traffic study recommended that the proposed project mitigate its significant contribution of traffic at the intersection of Seal Beach Boulevard and Rossmoor Center Way through a fair share contribution towards improvements to alleviate existing queuing deficiencies. Existing and potential queuing deficiencies and mitigation are described herein.

Evaluation of Environmental Impacts 78 Initial Study On-Site Circulation and Queuing to Enter Site This section presents the results of the site access assessment conducted for Existing (2014) and Existing (2014) with Full Occupancy plus health club conditions performed by LSA. As presented previously in this report, both project driveways and site adjacent intersections are anticipated to operate at satisfactory LOS for all analysis scenarios. As part of the site access assessment, existing and potential turn-pocket queuing issues at site access points and site adjacent intersections were analyzed using a simulation model. SimTraffic (Version 8.0) software. Due to variability that arises from simulations of this nature, multiple simulation runs for each analysis scenario were averaged to draw representative queuing results. This method more accurately measures the full impact of queuing and blocking of traffic. Queuing results for Existing (2014) with Full Occupancy without and with health club traffic conditions are shown on Table 29 (Site Access Queuing Summary). As shown on Table 29, all existing peak-hour queues at site access points and site-adjacent intersections are anticipated to be sufficiently stored by existing facilities with the exception of the northbound left-turn pocket at the intersection of Seal Beach Boulevard and Rossmoor Center Way. Based on the results of this assessment, the proposed retiming and reservicing of northbound left-turn movements at the intersection of Seal Beach Boulevard/Rossmoor Center Way can reduce the anticipated queues associated with the addition of the proposed project to approximately existing queue lengths associated with existing traffic and existing signal timing. These northbound left-turn queues are still anticipated to exceed the existing storage length by approximately 95 feet. Improvements to provide sufficient storage to this northbound left-turn queue include the lengthening of the existing northbound left-turn pocket to provide for approximately 200 feet of storage with or without the reservicing of northbound left-turn movements. There is sufficient space to extend this pocket to this length without modifying the unsignalized southbound left-turn pocket south of this location. Due to the anticipated need for extension of northbound left-turn lane storage at the intersection of Seal Beach Boulevard/Rossmoor Center Way for all assessed alternatives (200 total feet of storage without and with reservicing), the extension of the northbound left-turn storage lane at the intersection of Seal Beach Boulevard/Rossmoor Center Way is recommended over the addition of a second northbound left-turn lane due to the relative lack of interference with existing geometrics and consistency with length of other left-turn pockets south of Rossmoor Center Way along Seal Beach Boulevard. The implementation of dual northbound left-turn lanes is not recommended due to the relatively low left-turning volumes (200 in the Saturday midday peak hour) and likelihood of unequal lane utilization. The Federal Highway Administration (FHWA) recommends consideration of dual left-turn lanes when left-turn volumes exceed 300 vehicles per hour (assuming moderate levels of opposing through traffic and adjacent street traffic) and discourages dual left-turn lanes where left- turning vehicles are not expected to evenly distribute themselves among lanes (Signalized Intersections: Informational Guide, FHWA, August 2004). The northbound left-turn lane at the intersection of Seal Beach Boulevard/Rossmoor Center Way can be extended to 250 feet of storage with a 90-foot transition. A storage length of 250 feet can be accommodated without shortening the adjacent southbound left-turn lane storage with some restriping of the southbound turn pocket. A storage length of 250 feet, or two vehicle design lengths beyond the anticipated 95th percentile queue, is recommended in an effort to keep northbound left-turn queues out of the northbound through lanes in the unlikely instances where the 95th percentile queues may be exceeded. This length will not affect the storage length of the southbound left-turn pocket to the south of this pocket. The transition/taper length of these back- to-back turn pockets can be shared. The modified median will vary between two and four feet and may not be able to accommodate landscaping (see Figure 6) Evaluation of Environmental Impacts Rossmoor Health Club 79 In an effort to determine the extent of the proposed project’s contribution to this existing and future queuing deficiency, the percentage of northbound left-turning vehicles attributable to the project has been calculated (see Appendix B). With construction of the recommended improvements, queues at the left-turn pocket from northbound Seal Beach Boulevard to Rossmoor Center Way are anticipated to be sufficiently stored so as to not exceed City standards for queuing at intersections. The applicant will be required to include these improvements as part of project approval. Impacts related to queuing at project intersections will be less than significant with construction of the recommended left-turn pocket improvements. Mitigation Measure T-1: Prior to issuance of occupancy permits, the project proponent shall extend the queuing length of the left-turn pocket lane from northbound Seal Beach Boulevard onto westbound Rossmoor Center Way, as recommended in the revised queuing analysis dated April, 2016 for the project traffic impact analysis to the satisfaction of the City Engineer. The City may determine a fair-share payment for completion of such improvements.

(Shade) = Exceeds existing storage length Evaluation of Environmental Impacts Rossmoor Health Club 81 Evaluation of Environmental Impacts 82 Initial Study Parking A parking analysis to review the parking supply and demand for the proposed health club since the facility would displace existing spaces for the existing retail center. Through previous entitlements acquired by the Shops at Rossmoor from the City, the commercial center currently has 2,068 existing parking spaces. With completion of the proposed project, the total number of parking spaces in the center will be reduced to 1,981 spaces. With the proposed project a total of 1,645 spaces are required at the Shops at Rossmoor. Thus, adequate parking supply within the Shops at Rossmoor will be provided. Although the Shops at Rossmoor retail center is private property, some residents of adjacent condominium communities have been observed to utilize retail center parking spaces for their vehicles when not conducting business at the retail center. However, this use is not authorized. This analysis investigates whether the reduced parking supply can adequately meet future parking demand or whether increased enforcement of parking policy will be necessary to ensure adequate parking supply for retail and health club patrons. Existing Parking Conditions The proposed health club facility would be built in an existing parking lot within the Shops at Rossmoor. The affected parking lots are shown on Exhibit 7 (Existing Parking Zones) and divided into two zones. Parking lot usage surveys were conducted on a typical weekday (Thursday, November 13, 2014) and again on a typical weekend, (Saturday, November 15, 2014). As shown on Tables 30 (Weekday Parking Utilization Summary) and 31 (Weekend Parking Utilization Summary), existing parking facilities were not fully utilized, with at least 25% of the spaces available.

Table 11.4.20.015.A.1 requires that gyms and fitness studios with more than 20,000 square feet provide one parking space per 300 square feet of development. Thus, 124 parking stalls are required to serve the proposed 37,000-square-foot fitness facility. In addition, development of the health club facility would result in a loss of approximately 40 parking spaces. Demand for these spaces would vary throughout the day. The Urban Land Institute (ULI) has collected data on the variation in parking demand for health clubs by time of day and has published that data in Shared Parking (Second Edition). Table 32 (Future Weekday Parking Demand) displays the anticipated variation in weekday parking demand generated by the proposed project and adds that to the observed existing parking demand to determine the anticipated total future parking demand. This total is compared to the future parking supply of 404 spaces to determine the number of spaces remaining. Table 33 (Future Weekend Parking Evaluation of Environmental Impacts Rossmoor Health Club 83 Demand) repeats this process for weekend parking demand. Exhibit 8 (Future Parking Zones) illustrates the future parking supply and peak parking demand by zone. Evaluation of Environmental Impacts 84 Initial Study Exhibit 6 Existing Parking Zones Evaluation of Environmental Impacts Rossmoor Health Club 85 Evaluation of Environmental Impacts 86 Initial Study There are 17 parking stalls in Zone 2 that are reserved for the Farmers and Merchants Bank building, per the Fifth Amendment to Declaration of Covenants, Conditions and Restrictions and Grant of Easements (Effective March 31, 2014). Tables 32 and 33 have included these 17 reserved parking stalls as part of the future parking demand. As shown on Tables 32 and 33, sufficient parking will be provided in the weekday and weekend by the combination of Parking Zones 1 and 2 to accommodate future demand, which includes buildout of the retail center and the proposed health club facility. Impacts related to parking demand and supply will be less than significant.

The Congestion Management Program (CMP) is administered by the Orange County Transportation Authority (OCTA). The CMP establishes a service goal of LOS E or better on all CMP roadway segments. There are no CMP intersections, roadway segments, or highway segments in close proximity to the project site. None of the traffic study intersections or roadway segments is included in the OCTA CMP.41 As identified in Section 4.16.a above, the proposed health club would result in 1,218 new trips. The project would not, therefore, conflict with an applicable congestion management program or level of service standard established by the congestion management agency. No impact would occur. c)No Impact. The project site is located within the planning area of an airport land use plan; however, the project does not include any structures that would change air traffic patterns or uses that would generate air traffic. Furthermore, the proposed building height (35 feet at its highest point) would not affect airport approach or departure spaces or any air traffic patterns. Therefore, no impacts related to a change in air traffic patterns would occur. d)No Impact. Access to the project site is proposed via two driveways on Rossmoor Center Way. The site can also be accessed via Towne Center Drive from a driveway that enters the Shops at Rossmoor from Seal Beach Boulevard. Extension of the left-turn pocket from northbound Seal Beach Boulevard onto Rossmoor Center Way will be extended an additional 125 to accommodate anticipated increases in queuing. The design of the proposed project and associated circulation improvements would comply with all applicable City regulations. Furthermore, the proposed project does not involve changes in the alignment of Seal Beach Boulevard or Rossmoor Center Way, which are adjacent to the project site. The left-turn pocket extension would not revise Seal Beach Boulevard’s alignment or increase hazards. No line of sight issues will occur on the driveways located on Rossmoor Center Way with inclusion of a six-foot easement along the health 41 Orange County Transportation Authority. 2011 Orange County Congestion Management Program. 2011. Evaluation of Environmental Impacts 88 Initial Study club northern boundary. As such, impacts related to roadway design features and incompatible uses would be less than significant. e) Less Than Significant Impact. A significant impact would occur if the design of the proposed project would not satisfy emergency access requirements of the Orange County Fire Authority or in any other way threaten the ability of emergency vehicles to access and serve the project site or adjacent uses. The proposed project would not result in inadequate emergency access. As discussed above, access to the project site is proposed via two driveways on Rossmoor Center Way and an additional entrance into the Shops at Rossmoor on Seal Beach Boulevard. The width of these driveways, as well as internal drive aisles, is sufficient to provide access for fire and emergency vehicles and is consistent with the California Fire Code. All access features are subject to and must satisfy the City of Seal Beach and Orange County Fire Authority design requirements. This project would not result in adverse impacts with regard to emergency access. Impact would be less than significant. f) Less than Significant Impact. Public bus transit service in the project vicinity is currently provided by the Orange County Transportation Authority (OCTA) Bus Route 42 on Seal Beach Boulevard. This line runs at a high frequency (every 15 minutes or better) over a long service day, with service late into the evening and on weekends. The proposed project would not result in any substantial changes to lane or street configuration of Seal Beach Boulevard, any surrounding streets, or to existing sidewalks. Seal Beach Boulevard is not equipped with striped bicycle lanes. While a left-turn pocket lane will be extended on Seal Beach Boulevard, this traffic improvement would not demonstrably affect performance or safety of alternative transportation facilities. During project construction, temporary closures of sidewalk areas would be required. However, these closures would be short term in nature, and appropriate signage would be required to direct pedestrians around the closure. Lane closures associated with extension of the left-turn pocket lane would be coordinated and limited to the left-turn pocket and median. Impacts would be less than significant. Evaluation of Environmental Impacts Rossmoor Health Club 89 4.17 – Utilities and Service Systems Would the project: Potentially Significant Impact Less Than Significant with Mitigation Incorporation Less Than Significant Impact No Impact a)Exceed wastewater treatment requirements of the applicable Regional Water Quality Control Board? □□□ b)Require or result in the construction of new water or wastewater treatment facilities or expansion of existing facilities, the construction of which could cause significant environmental effects? □□□ c)Require or result in the construction of new storm water drainage facilities or expansion of existing facilities, the construction of which could cause significant environmental effects? □□□ d)Have sufficient water supplies available to serve the project from existing entitlements and resources, or are new or expanded entitlements needed? □□□ e)Result in a determination by the wastewater treatment provider which serves or may serve the project that it has adequate capacity to serve the project’s projected demand in addition to the provider’s existing commitments? □□□ f)Be served by a landfill with sufficient permitted capacity to accommodate the project’s solid waste disposal needs? □□□ g)Comply with federal, state, and local statutes and regulations related to solid waste?□□□ Evaluation of Environmental Impacts 90 Initial Study a) Less Than Significant Impact. The proposed project could affect Regional Water Quality Control Board treatment standards by increasing wastewater production, which would require expansion of existing facilities or construction of new facilities. Exceeding the RWQCB treatment standards could result in contamination of surface or ground waters with pollutants such as pathogens and nitrates. The project site is served by a public sewer system. All wastewater generated by the proposed project would be discharged into the local sewer main and conveyed for treatment at the Orange County Sanitation Districts (OCSD) reclamation plants. OCSD, under contract with Seal Beach, collects and treats wastewater at regional facilities. According to the 2010 Urban Water Management Plan for the City of Seal Beach, OCSD’s collection system eventually feeds into the OCSD Plant No. 2 located at 22212 Brookhurst Street in the City of Huntington Beach. OCSD Plant 2 has a treatment capacity of 70 million gallons per day (MGD).42 Based on the CalEEMod default estimates for water use, the health club would use approximately 3,551,450 gallons of water annually, which includes both indoor uses such as showers and drinking fountains and outdoor use such as sprinklers for landscaping. Generally, wastewater is approximately 80% of total water demand. As such, the project is estimated to generate approximately 2,841,160 gallons of wastewater per year, or 7,784 gallons per day (gpd). This volume is well within the remaining treatment capacity of OCSD Plant No. 2. This project would thus have a less-than-significant impact on the ability of the facility to operate within its established wastewater treatment requirements, which are enforced via the facility’s NPDES permit authorized by the Santa Ana Regional Water Quality Control Board. Wastewater flows associated with the proposed project would consist of the same kinds of substances typically generated by commercial uses, and no modifications to any existing wastewater treatment systems or construction of any new ones would be needed to treat this project’s wastewater. The ultimate disposal of effluent and solids would occur in compliance with waste discharge requirements set by the California RWQCB. Wastewater conveyed from the site would undergo treatment in accordance with applicable regulations, including the requirements of the RWQCB. The project would have a less than significant impact related to wastewater treatment requirements. b) Less Than Significant Impact. The City provides water to a population of 25,561 throughout its service area. The City receives its water from two main sources: 1) the Lower Santa Ana River Groundwater basin, which is managed by the Orange County Water District (OCWD) and 2) imported water from the Municipal Water District of Orange County (MWDOC). Groundwater is pumped from three active wells located throughout the City, and imported water is treated at the Diemer Filtration Plant and delivered to the City via imported water connections. Regarding wastewater facilities, as discussed in the preceding response, wastewater generated at the project site is treated at OCSD Plant No. 2. The proposed project is estimated to have a wastewater generation of approximately 7,784 gpd. As stated in section 4.17.a, this generation is well within the existing remaining treatment capacity of OCSD Plant No. 2. No additional improvements are anticipated to either sewer lines or treatment facilities to serve the proposed project, as the project represents a very small use in the context of all development served. Standard connection fees will address any incremental impacts of the proposed project. Therefore, the project would result in less than significant impacts. 42 City of Seal Beach. 2010 Water Quality Management Plan. July 2011. Evaluation of Environmental Impacts Rossmoor Health Club 91 c)Less Than Significant Impact. As discussed in the Hydrology section, the proposed project would not generate substantially increased runoff from the site that would require construction of new storm drainage facilities. In fact, the project would increase the total pervious surfaces on the site due to increased landscaping. As indicated in the engineering analysis conducted for the proposed project, total discharge rates for onsite drainage would decrease from 5.70 cubic feet per second (cfs) to 4.44 cfs for drainage Area A, and from 1.55 cfs to 1.53 cfs for drainage Area B.On-site Soils are not suitable for a stormwater infiltration system to reduce the flow level, and store and reuse is not technically feasible because the landscape areas are not large enough to accommodate the required re-use quantity. However, the project would include measures to treat stormwater flows on site through modular wetland biofiltration and a number of structural and non-structural source control BMPs before entering the municipal storm drain system. The expected decrease in stormwater flow and implementation of these measures mean that no new facilities or expansion of existing storm drainage facilities is required, as current levels can be accommodated by existing storm drainage facilities. An NPDES permit would be required for the proposed project, which requires adoption of appropriate Stormwater Pollution Prevention Plan (SWPPP) and implementation of Best Management Practices (BMPs). The proposed project’s storm drainage system would include the above mentioned measures to ensure the storm water would be cleaned and retained onsite to a level equal to or greater than the NPDES mandates. Implementation of BMPs would reduce pollutants in stormwater and urban runoff from the project site. The proposed storm drainage system, in combination with the SWPPP and BMPs, must be designed to the satisfaction of the City’s Public Works Director and in conformance with all applicable permits and regulations. The project applicant/developer would be required to provide all necessary on-site drainage infrastructure. Impact would be less than significant, and no mitigation beyond compliance with existing laws is required. d)Less Than Significant Impact. According to the City of Seal Beach 2010 Urban Water Management Plan (UWMP), the City has the rights to pump approximately 2,853 total acre-feet per year (afy) of water from its three wells. The UWMP reported an estimated total demand of 4,610 afy in fiscal year 2009-2010. This total includes 1,750 afy of imported water and 2,850 afy of local groundwater. Estimated demand in 2015-2016 (at the time of the proposed project completion) is predicted to be 4,720 afy; demand in 2030 is projected to be 4,880 afy. Cumulative supply from the Central Basin and Main basin exceed projected demand in 2014-2015 and 2029-2030. The proposed project would generate a marginal increase in additional demand for water relative to overall existing citywide demand. Based on the CalEEMod default estimates for water use, the health club would use approximately 3,551,450 gallons of water annually, which includes both indoor uses such as showers and drinking fountains and outdoor use such as sprinklers for landscaping. Water use by the building would be roughly 9,730 gallons per day, or approximately 11 afy. As the UWMP anticipates an overall increase in demand associated with development in the area over 2010 conditions, and the water demand for this project is within that demand assumption, impacts would be less than significant. The project would not substantially deplete water supplies, and the project would have a less than significant impact on entitled water supplies. The project would be required to comply with Chapter 10.40 (Streetscape) and 11.4.30 (Landscaping and Buffer Yards) of the City of Seal Beach Municipal Code, which would lessen the project’s demand for water resources. Also, CBC Title 24 water efficiency measures require a demonstrated 20 percent reduction in the use of potable water. The project’s landscaping plans Evaluation of Environmental Impacts 92 Initial Study include drought-tolerant landscaping materials. Compliance with Title 24 and the City’s Water Conservation in Landscaping and Water Efficient Landscaping Ordinances would reduce the proposed project’s impacts to groundwater supplies to a level of less than significant. e) Less Than Significant Impact. As detailed in Sections 4.17a and 4.17b, the proposed project would be adequately served by existing wastewater conveyance and treatment facilities. Impact would be less than significant impact. f) Less Than Significant Impact. A commercial retail use is estimated to produce 2.5 pounds per 100 square feet per day.43 According to this measure, the health club would produce approximately 931 pounds of waste per day. However, the health club is likely to produce significantly less waste than the average commercial retail use, as limited packaging materials are used and the use is generally service-oriented. According to CalEEMod default settings for waste production, the proposed health club would produce 213 tons of waste annually, or 117 pounds per day. Consolidated Disposal Services, LLC (Republic Services) provides exclusive waste and recycling collection services for residential and commercial uses in the City of Seal Beach.44 Republic Services currently operates three landfills in the Los Angeles/Orange County area in Long Beach, Gardena, and Anaheim. Republic Services also has recycling operations at their Anaheim facility, as well as at their BFI Falcon transfer station in Wilmington. Republic Services landfills currently have sufficient capacity to serve the City of Seal Beach now and into the future. The addition of 117 pounds per day of solid waste and recycling materials will not exceed the waste treatment capacity of Republic Services. Considering the availability of landfill capacity and the relatively nominal amount of solid waste generation from the proposed project, project solid waste disposal needs can be adequately met without a significant impact on the capacity of Republic Services landfills. Impacts would be less than significant. g) No Impact. The proposed project is required to comply with all applicable federal, state, County, and City statutes and regulations related to solid waste as a standard project condition of approval. Therefore, no impact would occur. 43 Republic Waste Services of Southern California. Loading Factors. July 2011. 44 Republic Services Website.

Evaluation of Environmental Impacts Rossmoor Health Club 93 4.18 – Mandatory Findings of Significance Potentially Significant Impact Less Than Significant with Mitigation Incorporation Less Than Significant Impact No Impact a)Does the project have the potential to degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self- sustaining levels, threaten to eliminate a plant or animal community, reduce the number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major periods of California history or prehistory? □□□ b)Does the project have impacts that are individually limited, but cumulatively considerable?□□□ c)Does the project have environmental effects which will cause substantial adverse effects on human beings, either directly or indirectly? □□□ a)Less Than Significant. The proposed project would not impact any scenic vista or scenic resource, nor would it degrade the visual character of the area, as discussed in Section 4.1. The project would not result in excessive light or glare. The project site is located within an urbanized area with no natural habitat. The project would not impact any sensitive plants, plant communities, fish, wildlife or habitat for any sensitive species, as discussed in Section 4.4. Adverse impacts to archaeological and paleontological resources would not occur. Construction- phase procedures would be implemented in the event any important archaeological or paleontological resources are discovered during grading, consistent with required state laws. This site is not known to have any association with an important example of California’s history or prehistory. The environmental analysis provided in Section 4.2 concludes that impacts related to emissions of criteria pollutants and other air quality impacts will be less than significant. Sections 4.7 and 4.9 conclude that impacts related to climate change and hydrology and water quality will be less than significant. Based on the preceding analysis of potential impacts in the responses to items 4.1 thru 4.17, no evidence is presented that this project would degrade the quality of the environment. The City hereby finds that impacts related to degradation of the environment, biological resources, and cultural resources would be less than significant. Evaluation of Environmental Impacts 94 Initial Study b) Less Than Significant. Cumulative impacts can result from the interactions of environmental changes resulting from one proposed project with changes resulting from other past, present, and future projects that affect the same resources, utilities and infrastructure systems, public services, transportation network elements, air basin, watershed, or other physical conditions. Such impacts could be short-term and temporary, usually consisting of overlapping construction impacts, as well as long term, due to the permanent land use changes involved in the project. The proposed health club would result in less than significant environmental impacts (with mitigation incorporated), as discussed in this Initial Study. Short-term impacts related to noise would be less than significant and therefore would not contribute substantially to any other concurrent construction programs that may be occurring in the vicinity. Short-term impacts related to pollutant emissions would be less than significant and would not exceed thresholds. To assess potential cumulative impacts associated with this project, an inventory of other proposed development projects was prepared. Currently, only one nearby cumulative development was identified: a new car wash within an existing Mobil service and gas station at the northeast corner of Seal Beach Boulevard and Rossmoor Center Way/Plymouth Drive. The proposed project, in combination with this project, would not significantly cumulatively affect the environment. Water supplies have been studied in the City’s UWMP, and the cumulative projects are accounted for in UWMP. Continued efforts towards water conservation, as required by state law, would reduce water demands; the project would result in a less-than-significant cumulative impact on water supply and other resources. As indicated in Section 4.16, the proposed project would not result in any significant traffic impacts to traffic or transportation. c) Less Than Significant with Mitigation Incorporation. Based on the analysis of the proposed project’s impacts in the responses to items 4.1 thru 4.17, no evidence indicates that this project could result in substantial adverse effects on human beings. While project construction would result in temporary noise impacts and criteria pollutant emissions, these would be minimized to acceptable levels through application of routine construction control measures. Long-term effects would include increased vehicular traffic, traffic-related noise, periodic on-site operational noise, minor changes to on-site drainage, and a minor change to the visual character of the site. None of these effects would be significant. Projected emission levels would be below the thresholds of significance recommended by the South Coast Air Quality Management District. Project-related traffic would represent a small percentage increase in traffic volumes along nearby roadways and would have a less-than-significant impact on roadway noise levels. The analysis concludes that direct and indirect environmental effects would result in less than significant impacts, with mitigation applied to address construction noise and long-term traffic impacts. Based on the analysis in this Initial Study, the City finds that direct and indirect impacts to human beings would be less than significant with mitigation incorporated.

RICHMOND RIVERSIDE ROCKLIN SAN LUIS OBISPO PLANNING  ENVIRONMENTAL SCIENCES  DESIGN April 6, 2016 Bill Estenger, PE Jones Lang LaSalle 4 Park Plaza, Suite 900 Irvine, CA 92614 Subject: Revised Health Club within the Shops at Rossmoor Expanded Queuing Assessment Dear Mr. Estenger: LSA Associates, Inc. (LSA) is pleased to submit this revised queuing assessment that evaluates the effectiveness of potential intersection improvements based on the expansion of the Shops at Rossmoor to include a health club facility. This supplemental analysis has been prepared based on discussions with City of Seal Beach (City) staff as a result of their review of the traffic study that was prepared for the project, (Health Club within the Shops at Rossmoor Traffic Analysis, LSA, 2015). Specifically, potential improvements to the City intersections of Seal Beach Boulevard/Rossmoor Center Way, Seal Beach Boulevard/Town Center Drive and Internal Driveways/Rossmoor Center Way have been assessed. The improvements include physical (added turn lanes) and/or operational changes (e.g., signal timing changes and signal phasing changes). This revised assessment includes new data provided by the City for signal timing that was implemented in March 2016. This assessment was based on existing signal timing data sent by the City of Seal Beach and the City of Los Alamitos staff. The assessment has been conducted for the following scenarios: Existing Geometrics with existing signal timing Existing Geometrics with optimized signal timing and signal phase changes Dual northbound left turns at Seal Beach Boulevard/Town Center Drive VOLUME DEVELOPMENT AND METHODOLOGY Traffic volumes assessed in this effort are consistent with those presented in the traffic analysis. The analysis evaluates typical weekday a.m. and p.m. peak hours as well as the Saturday midday peak hour. Turn-pocket queuing and intersection performance have been conducted using Synchro Version 9.1 and SimTraffic Version 9.1 software. Signalized and unsignalized intersection performance has been analyzed by calculating delay experienced by vehicles using methods published in the Highway Capacity Manual (HCM). Synchro is a software tool that can determine (macro level) levels of service (LOS) and delays according to methods consistent with the HCM methodology and has been utilized in this assessment to analyze intersection and arterial performance. 4/6/16 «P:\MPA1401\TIA\Additional Queue Analysis.City rev3.docx» 2 LSA ASSOCIATES, INC. SimTraffic is a microsimulation tool that builds on the operational data analyzed by Synchro and adds elements of randomization as it produces simulations of traffic moving through the modeled roadway network. Due to the geometric specificities unique to the study area that are reflected in the model and the elements of randomization produced by the simulation of discrete vehicle behavior, SimTraffic can provide a more extensive look at traffic conditions such as queuing at intersections. As such, SimTraffic has been utilized to simulate 95th percentile queues at the study intersection turn pockets. The 95th percentile queues presented by SimTraffic represent the highest 95th percentile of queues observed within the traffic simulation. As such, the 95th percentile queue does not represent the anticipated average queue lengths, but rather a conservative “worst-case” queue based on the worst 95th percentile. The operational analysis conducted by the Synchro and SimTraffic software packages utilizes factors such as signal timing and the interaction with adjacent intersections. In order to take into account the potential effect, if any, of operational timing alternatives of the study area intersections along the Seal Beach Boulevard corridor, the following intersections were incorporated in this assessment:  Seal Beach Boulevard/St. Cloud Drive;  Seal Beach Boulevard/Town Center Drive;  Seal Beach Boulevard/Rossmoor Center Way;  Seal Beach Boulevard/Bradbury Road;  Los Alamitos Boulevard/Orangewood Avenue;  Los Alamitos Boulevard/Farquhar Avenue; and  Los Alamitos Boulevard/Katella Avenue. The intersections along Los Alamitos Boulevard were taken into consideration due to concerns of City staff regarding potential effects on the coordination of the corridor. These specific intersections were selected based on their inclusion as study area intersections in the City of Los Alamitos General Plan: Mobility and Circulation Element (Placeworks, March 2015). According to signal timing information provided by the City in March 2016, the preferred signal timing cycle length for the signalized intersections along Seal Beach Boulevard between St. Cloud Drive and Rossmoor Center Way is 120 seconds per cycle. Signal timing information north of Rossmoor Center Way along Seal Beach Boulevard/Los Alamitos Boulevard up to Katella Avenue was previously obtained from the Cities of Seal Beach and Los Alamitos. In an effort to maintain the existing north-south coordination along Seal Beach Boulevard/Los Alamitos Boulevard, the various improvements assessed in this effort have maintained the existing cycle lengths at all signalized intersections along Seal Beach Boulevard/Los Alamitos Boulevard south of Katella Avenue. Existing signal timings were optimized for the existing traffic volumes and lane geometrics. Proposed improvements included signal phasing modifications performed with an objective of minimizing turn-pocket queues while simultaneously maintaining acceptable LOS “D or better” (consistent with standards utilized in the traffic analysis) at each of the study intersections. The signal timings and phasings were also adjusted to optimize the northbound and southbound arterial segment performance of Seal Beach Boulevard/Los Alamitos Boulevard. 4/6/16 «P:\MPA1401\TIA\Additional Queue Analysis.City rev3.docx» 3 LSA ASSOCIATES, INC. As shown in Table A (attached), the existing northbound left-turn pocket at the intersection of Seal Beach Boulevard/Rossmoor Center Way currently provides approximately 105 feet (ft) of storage while the existing northbound left-turn pocket at the intersection of Seal Beach Boulevard/Town Center Drive currently provides approximately 180 ft of storage. In addition, the segment of Rossmoor Center Way east of the internal driveway within the Shops at Rossmoor and west of Seal Beach Boulevard is approximately 230 ft. EXISTING INTERSECTION OPERATIONS The anticipated queues and their respective peak-hour intersection LOS for each of the scenarios listed above are summarized in Table A. Turn-pocket queuing, HCM intersection LOS worksheets, and HCM arterial segment LOS worksheets are provided in Attachments A, B, and C, respectively. The existing conditions of the study intersections and related queue lengths found in Table A are discussed below. Existing Signal Timing The existing signal timing scenario provides a baseline for turn-pocket queues and intersection operations from which all potential improvements can be compared. The signal timings utilized in this scenario are based on the signal timing inputs provided by the Cities of Seal Beach and Los Alamitos for each of the study intersections and then optimized in a manner to prioritize overall intersection operations and arterial performance over queuing issues at turn pockets. In an effort to demonstrate potential increases in queues and intersection delay, two sets of conditions have been presented for this scenario. The Existing with Full Occupancy conditions represent a without project condition while the Existing with Full Occupancy plus Project conditions represent anticipated conditions inclusive of the proposed health club. These conditions are consistent with those analyzed in the traffic analysis. A discussion of the existing intersection and queuing performance at each of the study intersections in question is shown below: Seal Beach Boulevard/Town Center Drive. As shown in Table A, the northbound left-turn lane at this intersection is anticipated to experience queuing beyond the existing storage length without and with the development of the proposed project. The 95th percentile queue for the northbound left-turn lane is anticipated to exceed the current storage length by up to approximately 110 ft without and with the development of the proposed project during the Saturday midday peak hour. Seal Beach Boulevard/Rossmoor Center Way. As shown in Table A, the northbound left-turn lane at this intersection is anticipated to experience queuing beyond the existing storage length without and with the development of the proposed project. The development of the project is anticipated to result in no meaningful increase to the 95th percentile queue for the northbound left- turn lane. The 95th percentile queue for the northbound left-turn lane is anticipated to exceed the current storage length by up to approximately 95 ft without and with the development of the proposed project during the Saturday midday peak hour. The development of the project is 4/6/16 «P:\MPA1401\TIA\Additional Queue Analysis.City rev3_.docx» 4 LSA ASSOCIATES, INC. anticipated to result in an increase of the 95th percentile queue from 245 ft to 260 ft for the eastbound left-turn lane at Seal Beach Boulevard/Rossmoor Center Way during the Saturday midday peak hour. This represents a 30 ft overflow of the existing 230 ft eastbound left-turn lane, or approximately one design vehicle length of 25 ft. This would not mean that vehicles are necessarily queued in the middle of the intersection. It is more likely that outbound vehicles from the northbound, southbound, and eastbound approaches at the internal intersection west of Seal Beach Boulevard are waiting at their respective stop-controlled approaches for queued vehicles to move onto Seal Beach Boulevard. These simulated queues are consistent with queues observed during field visits made by LSA staff in March 2016.  Internal Driveway/Rossmoor Center Way. As shown in Table A, no queuing issues are anticipated at the eastbound and westbound approaches regardless of the development of the proposed project. INTERSECTION IMPROVEMENT ALTERNATIVES A discussion of the intersection operations and queuing performance associated with each of the improvement alternatives assessed in this analysis are summarized below. LOS for northbound and southbound through movements along the signalized intersections and arterial segments of Seal Beach Boulevard/Los Alamitos Boulevard were optimized under all improvement alternatives where optimization of the signal timings was performed. LOS worksheets detailing the performance of northbound and southbound through movements along the signalized intersections and arterial segments of Seal Beach Boulevard/Los Alamitos Boulevard are included in Attachments B and C, respectively. Optimized Signal Timing with Reservicing for Northbound Left Turns onto Town Center Drive and Rossmoor Center Way The optimized signal timing with reservicing for northbound left turns onto the Town Center Drive and Rossmoor Center Way scenario is a proposed improvement scenario in which no geometric improvements are implemented. Reservicing consists of allowing northbound left turns to occur twice every cycle, by providing both a “lead” and a “lag” phase for the northbound left-turn movement during periods of heavy queuing, such as the weekday p.m. peak hour and the Saturday midday peak hour. As shown in Table A, this improvement can help reduce the peak-hour queues that currently exceed provided storage lengths to below existing levels at the intersection of Seal Beach Boulevard/Rossmoor Center Way (i.e., 208 ft) but not enough to eliminate the need to provide additional queuing storage. In addition, LOS at the intersections along Los Alamitos Boulevard is not affected by the proposed signal timing at Seal Beach Boulevard/Rossmoor Center Way. As shown in Table A, the development of the project in conjunction with this improvement alternative may add approximately 24 ft, or less than one 25 ft design vehicle, to the eastbound left- turn lane at Seal Beach Boulevard/Rossmoor Center Way. This eastbound left-turn queue storage is anticipated to be exceeded by the 95th percentile queue during one or more peak hours without or with the project, regardless of timing alternative. As this 95th percentile queue never exceeds the provided storage by 25 ft, or one design vehicle length, during the worst 5 percent of a peak hour (approximately 3 times per peak hour), this excess queue is not considered significant. 4/6/16 «P:\MPA1401\TIA\Additional Queue Analysis.City rev3.docx» 5 LSA ASSOCIATES, INC. Dual Northbound Left Turns onto Town Center Drive Dual northbound left-turn lanes at the intersection of Seal Beach Boulevard/Town Center Drive have also been assessed in an effort to alleviate queuing issues that, as shown in Table A, currently exist during the weekday p.m. and Saturday midday peak hours. Project traffic was not added to this access point. Based on the location of the project, it would be a circuitous route for members of the health club to drive into the retail center at Town Center Drive and traverse through several parking lots and avoid pedestrians to arrive at the project site. Even if approximately 5–10 percent of project traffic was to enter via Town Center Drive, this would represent only 4–8 inbound vehicles in a peak hour which would not significantly affect the queuing at Seal Beach Boulevard/Town Center Drive. As shown in Table A, the addition of a second northbound left-turn lane at Seal Beach Boulevard/ Town Center Drive will reduce the anticipated 95th percentile northbound left-turn queues to fit within two 180 ft storage lanes. This improvement will not affect the northbound left-turn queues at Seal Beach Boulevard/Rossmoor Center Way. This improvement, however effective, is not recommended at this time due to the relative infrequency of 95th percentile northbound left-turn queues exceeding the existing storage length and the requisite need for additional right-of-way that currently does not exist. QUEUING AT THE INTERNAL DRIVEWAY/ROSSMOOR CENTER WAY Potential queuing issues at the internal driveway on Rossmoor Center Way related to the adjacent proposed improvements at Seal Beach Boulevard/Rossmoor Center Way were also assessed in an effort to identify any unforeseen internal queuing issues. As shown in Table A, eastbound queues on the west leg of the intersection of Seal Beach Boulevard/Rossmoor Center Way are anticipated to be adequately serviced under improvement scenarios in which two eastbound lanes are maintained. CONCLUSION AND RECOMMENDATIONS Based on the results of this assessment, the proposed retiming and reservicing of northbound left-turn movements at the intersection of Seal Beach Boulevard/Rossmoor Center Way can reduce the anticipated queues associated with the addition of the proposed project to approximately existing queue lengths associated with existing traffic and existing signal timing. These northbound left-turn queues are still anticipated to exceed the existing storage length by approximately 95 ft. Improvements to provide sufficient storage to this northbound left-turn queue include the lengthening of the existing northbound left-turn pocket to provide for approximately 200 ft of storage with or without the reservicing of northbound left-turn movements. There is sufficient space to extend this pocket to this length without modifying the unsignalized southbound left-turn pocket south of this location. Due to the anticipated need for extension of northbound left-turn lane storage at the intersection of Seal Beach Boulevard/Rossmoor Center Way for all assessed alternatives (200 total feet of storage without and with reservicing, the extension of the northbound left-turn storage lane at the intersection of Seal Beach Boulevard/Rossmoor Center Way is recommended over the addition of a second northbound left-turn lane due to the relative lack of interference with existing geometrics and 4/6/16 «P:\MPA1401\TIA\Additional Queue Analysis.City rev3.docx» 6 LSA ASSOCIATES, INC. consistency with length of other left-turn pockets south of Rossmoor Center Way along Seal Beach Boulevard. The implementation of dual northbound left-turn lanes is not recommended due to the relatively low left-turning volumes (200 in the Saturday midday peak hour) and likelihood of unequal lane utilization. The Federal Highway Administration (FHWA) recommends consideration of dual left-turn lanes when left-turn volumes exceed 300 vehicles per hour (assuming moderate levels of opposing through traffic and adjacent street traffic) and discourages dual left-turn lanes where left- turning vehicles are not expected to evenly distribute themselves among lanes (Signalized Intersections: Informational Guide, FHWA, August 2004). The northbound left-turn lane at the intersection of Seal Beach Boulevard/Rossmoor Center Way can be extended to 250 ft of storage with a 90 ft transition. A storage length of 250 ft can be accommodated without shortening the adjacent southbound left-turn lane storage with some restriping of the southbound turn pocket. A storage length of 250 ft, or two vehicle design lengths beyond the anticipated 95th percentile queue, is recommended in an effort to keep northbound left-turn queues out of the northbound through lanes in the unlikely instances where the 95th percentile queues may be exceeded. This length will not affect the storage length of the southbound left-turn pocket to the south of this pocket. The transition/taper length of these back-to-back turn pockets can be shared. The modified median will vary between 2 and 4 ft and may not be able to accommodate landscaping. Dual northbound left-turn lanes are not recommended at this time for the intersection of Seal Beach Boulevard/Town Center Drive due to the relative infrequency of 95th percentile northbound left-turn queues exceeding the existing storage length.

OCTOBER 2015 HEALTH CLUB WITHIN T HE SHOPS AT ROSSMOOR TRAFFIC ANALYSIS CITY OF SEAL BEACH, CALIFORNIA P:\MPA1401\TIA\Report rev4.docx «10/01/15» 1 EXECUTIVE SUMMARY LSA Associates, Inc. (LSA) has prepared the following traffic/circulation and parking analysis to identify any potential traffic and parking impacts resulting from the development of the proposed health club (project) in the City of Seal Beach (City). LSA has prepared this analysis consistent with the City Traffic Impact Study Guidelines (March 2010) and the City’s General Plan (December 2003). The project proposes the construction of a 37,000-square-foot (sf) health club within the Shops at Rossmoor retail center. This study analyzes the weekday a.m., p.m., and weekend mid-day peak hour levels of service (LOS) at 15 study area intersections and 11 roadway segments for the following scenarios: 1. Existing (2014) conditions with current occupancy of the Shops at Rossmoor retail center 2. Existing (2014) conditions with estimated full occupancy of the Shops at Rossmoor retail center 3. Existing (2014) conditions with estimated full occupancy of the Shops at Rossmoor retail center plus the proposed project 4. Project Completion Year (2016) conditions with estimated full occupancy of the Shops at Rossmoor retail center 5. Project Completion Year (2016) conditions with estimated full occupancy of the Shops at Rossmoor retail center plus the proposed project 6. Future (2035) General Plan Buildout conditions with estimated full occupancy of the Shops at Rossmoor retail center 7. Future (2035) General Plan Buildout conditions with estimated full occupancy of the Shops at Rossmoor retail center plus the proposed project Based on the results of this traffic analysis, all study area facilities are anticipated to operate at satisfactory LOS per City standards. This traffic analysis found that the northbound left-turn pocket at the intersection of Seal Beach Boulevard/Rossmoor Center Way is currently experiencing queuing issues and would require improvements. As a result, improvements have been recommended for this intersection to extend the storage lane to accommodate demand. Based on the parking assessment, the proposed parking supply is anticipated to sufficiently meet the demands of the estimated full occupancy of the Shops at Rossmoor and the proposed project per City standards. INTRODUCTION LSA has prepared this traffic/circulation analysis within a study area along Seal Beach Boulevard north of the Interstate 405 (I-405) freeway in the City of Seal Beach in order to identify any potential traffic impacts resulting from the development of the proposed project. The study area was developed in coordination with the City staff, which included intersections and roadway segments along Seal Beach Boulevard and local access roads adjacent to the proposed project. Per direction from the City, LSA also evaluated recent accident data in the study area and conducted a parking assessment for the LSA ASSOCIATES, INC. OCTOBER 2015 HEALTH CLUB WITHIN T HE SHOPS AT ROSSMOOR TRAFFIC ANALYSIS CITY OF SEAL BEACH, CALIFORNIA P:\MPA1401\TIA\Report rev4.docx «10/01/15» 2 proposed project. The traffic analysis has been prepared consistent with the City Traffic Impact Study Guidelines (March 2010) and the City’s General Plan (December 2003). The traffic analysis reviewed the weekday a.m., p.m., and weekend peak-hour LOS at study intersections and roadway segments for the following scenarios: 1. Existing (2014) conditions with current occupancy of the Shops at Rossmoor retail center 2. Existing (2014) conditions with estimated full occupancy of the Shops at Rossmoor retail center 3. Existing (2014) conditions with estimated full occupancy of the Shops at Rossmoor retail center plus the proposed project 4.

Project Completion Year (2016) conditions with estimated full occupancy of the Shops at Rossmoor retail center plus the proposed project 6. Future (2035) General Plan Buildout conditions with estimated full occupancy of the Shops at Rossmoor retail center 7. Future (2035) General Plan Buildout conditions with estimated full occupancy of the Shops at Rossmoor retail center plus the proposed project Health Club The proposed project consists of 37,000 sf of health club uses to be developed within the existing Shops at Rossmoor retail center along the south side of Rossmoor Center Way between West Road and Sprouts Farmers Market as shown on Figure 1. The project site is bound by residential uses to the north and west. Access to the project will be provided by the site adjacent intersections of West Road at Rossmoor Center Way and Project Driveway at Rossmoor Center Way. The development of the proposed project would require the loss of 14 parking spaces. STUDY AREA As shown on Figure 2, Seal Beach Boulevard is a north-south arterial that provides access to both residential and commercial (retail) uses within the City of Seal Beach. Seal Beach Boulevard is a six- lane Major Arterial per the City’s General Plan, which provides connection to the I-405 freeway as well as the Interstate 605 (I-605) freeway (via Katella Avenue). The 1.2-mile (mi) section of Seal Beach Boulevard between I-405 and Bradbury Road provides connection to commercial uses such as office, retail, and hotel, and residential uses (both east and west of Seal Beach Boulevard) via local collector streets such as Bradbury Road, Lampson Avenue, Rossmoor Center Way, Town Center Drive and St. Cloud Drive. There are retail/commercial uses on either side of Seal Beach Boulevard between St. Cloud Drive and Bradbury Road.

In order to analyze the traffic conditions along Seal Beach Boulevard when the Shops at Rossmoor is fully occupied, traffic for the unoccupied retail space was added to existing traffic volumes. Based on discussion with City staff and the criteria provided in the City’s Traffic Impact Study Guidelines, the following roadway segments and intersections are analyzed for the study: Roadway Segments:  Seal Beach Boulevard between: ○ Rossmoor Way and Bradbury Road ○ Bradbury Road and Rossmoor Center Way ○ Rossmoor Center Way and Town Center Drive ○ Town Center Drive and St. Cloud Drive ○ St. Cloud Drive and Lampson Avenue ○ Lampson Avenue and I-405 Northbound ramps  St. Cloud Drive between: ○ Seal Beach Boulevard and Yellowtail Drive  Montecito Road between: ○ Yellowtail Drive and Copa De Oro Drive ○ Copa De Oro Drive and Mainway Drive ○ Mainway Drive and Bradbury Road  Rossmoor Center Way between: ○ Montecito Road and Seal Beach Boulevard Intersections: 1.

Internal Driveway/Town Center Way (unsignalized) Figure 3 shows the existing intersection lane geometrics at all 15 intersections. METHODOLOGY To determine the peak hour intersection operations at signalized intersections within the study area, intersection capacity utilization (ICU) methodology was used per City of Seal Beach Traffic Study Guidelines. The ICU methodology compares the volume-to-capacity (v/c) ratios of conflicting turn movements at an intersection, sums these critical conflicting v/c ratios for each intersection approach, and determines the overall ICU. The resulting ICU is expressed in terms of LOS, where LOS A represents free-flow activity and LOS F represents overcapacity operation. The ICUs were developed for this study using the Traffix (Version 8.0) software. According to the City of Seal Beach Traffic Impact Study Guidelines, LOS at an intersection is considered to be unsatisfactory when the ICU exceeds 0.90 (LOS D). As such, improvements are recommended at locations that operate at LOS E or F. The relationship of ICU (v/c ratio) to LOS is demonstrated in the following table: LOS Operating Condition ICU (v/c ratio) A Free flowing, virtually no delay. Minimal traffic <0.60 B Free flow and choice of lanes. Delays are minimal. All cars clear intersection easily. 0.60–0.69 C State flow. Queue at signal starting to get relatively long. Delays starting to become a factor but still within “acceptable” limits. 0.70–0.79 D Approaching unstable flow. Queues at intersection are quite long but most cars clear intersection on their green signal. Occasionally, several vehicles must wait for a second green signal. Congestion is moderate. 0.80–0.89 E Severe congestion and delay. Most of the available capacity is used. Many cars must wait through a complete signal cycle to clear the intersection. 0.90–0.99 F Excessive delay and congestion. Most cars must wait through more than one on one signal cycle. Queues are very long and drivers are obviously irritated. >1.00 ICU = Intersection Capacity Utilization LOS = level of service v/c = volume-to-capacity 1 Seal Beach Blvd/I-405 SB Ramps 2 Seal Beach Blvd/I-405 NB Ramps 3 Seal Beach Blvd/Lampson Av 4 Seal Beach Blvd/Saint Cloud Dr 5 Seal Beach Blvd/Town Center Dr 6 Seal Beach Blvd/Rossmoor Center Wy 7 Seal Beach Blvd/Bradbury Rd 8 Yellowtail Dr/Saint Cloud Dr 9 Montecito Rd/Copa De Oro Dr 10 Montecito Rd/Rossmoor Center Wy 11 Montecito Rd/Bradbury Rd 12 West Rd/Rossmoor Center Wy 13 Project Dwy/Rossmoor Center Wy 14 Internal Dwy/Rossmoor Center Wy 15 Internal Dwy/Town Center Wy FIGURE 3 Legend SignalRight Turn Overlap Health Club within The Shops at Rossmoor Stop SignDefacto Right Turn Lane Free Right Turn Existing (2014) Lane Geometrics and Traffic Control Devices ad bd ac e xvvvt ab e accce wvvt ad wvvt be bc wvvt wu xvvvt aa d e vvvtt aa e aaccce accd f f bd f bd af wvvt ad ae e aaccd f bd d g wu bd b ad accd accd g bd wu cdbd ccce d u aef d g bd f yb F F F O O O D D O P:\MPA1401\Figures\Fig-03 Existing geo.xls\Figure (9/30/2015) LSA ASSOCIATES, INC. OCTOBER 2015 HEALTH CLUB WITHIN T HE SHOPS AT ROSSMOOR TRAFFIC ANALYSIS CITY OF SEAL BEACH, CALIFORNIA P:\MPA1401\TIA\Report rev4.docx «10/01/15» 8 Per City guidelines, the following project related increases in intersection ICU shall be deemed as “significant” and require mitigation: Existing ICU Project Related Increase in ICU 0.00-0.69 0.06 0.70-0.79 0.04 0.80-0.89 0.02 0.90+ 0.01 ICU = Intersection Capacity Utilization In addition to the ICU methodology of calculating signalized intersection LOS, the Highway Capacity Manual (HCM 2000) methodology was used to determine the LOS at the signalized ramp intersections that are governed by California Department of Transportation (Caltrans) and at unsignalized study area intersections. The HCM 2000 unsignalized intersection methodology presents LOS in terms of control delay (in seconds per vehicle). The resulting delay is expressed in terms of LOS, as in the ICU methodology. The relationship of delay to LOS is demonstrated in the following table: LOS Unsignalized Intersection Delay (seconds) A ≤10.0 B >10.0 and ≤15.0 C >15.0 and ≤25.0 D >25.0 and ≤35.0 E >35.0 and ≤50.0 F >50.0 ICU = Intersection Capacity Utilization LOS = level of service It should be noted that this study focuses on capacity (i.e., ICU). The HCM method is another method to evaluate operational conditions at signalized intersections, such as signal timing and queue lengths at turn lanes. While briefly discussed, this operational tool is not the focus of this study, although it is used to evaluate queuing at intersections as discussed later in this report. For roadway segments situated between intersections, LOS is described via a “mid-block roadway link” analysis. The Highway Capacity Software Version 5.2 (HCS) was utilized to analyze roadway segments in the study area consistent with Chapter 21 of the HCM. The basic input data for conducting a roadway analysis include the number of lanes and peak-hour volumes along the segments. Roadway segments have uniform traffic conditions and roadway characteristics. The measure used to provide an estimate of LOS is density, where density is calculated from the average vehicle flow rate per lane and the average speed. The following shows the correlation between LOS and flow density: LSA ASSOCIATES, INC.

EXISTING CONDITIONS Existing weekday a.m., p.m., and weekend mid-day peak-hour traffic conditions and LOS were analyzed for Existing (2014) conditions. LSA obtained intersection turn-movement counts at the 15 study area intersections for the weekday a.m. peak hour (7:00 a.m.–9:00 a.m.), the p.m. peak hour (4:00 p.m.–6:00 p.m.), and a weekend (Saturday) mid-day peak hour (11:00 a.m.–1:00 p.m.). Daily 24-hour counts were conducted for the 11 study area roadway segments in between the study area intersections. The counts were conducted by an independent car count company (National Data & Surveying Services [NDS]) for a weekday and weekend (Saturday) in November 2014. The traffic counts are included in Appendix A. The trips generated from surrounding existing land uses, which consist of residential and retail uses east and west of Seal Beach Boulevard, are included in the counts. Count data was collected after the completion of the Seal Beach Boulevard Bridge, outside of the West County Connector project detour periods that affect the flow of traffic along Seal Beach Boulevard, and before the week of the Thanksgiving holiday. LSA collected geometric, traffic control, and posted speed limit data at all study area locations. Figures 4 and 5 show the Existing (2014) peak-hour volumes at the study area intersections for weekday and weekend conditions, respectively. A summary of Existing (2014) LOS for intersections and roadway segments are presented in Tables A and B, respectively. The LOS worksheets for Existing (2014) conditions are included in Appendix B. As Tables A and B indicate, all study area intersections and roadway segments are currently operating at satisfactory LOS (LOS D or better). Accident History The City’s Traffic Impact Study Guidelines require the identification and analysis of intersections or roadway segments having five or more reported accidents within the most recent 12-month period. Five accidents is a generalized figure used by City staff as an indication of potential problems that could require improvements.

Table D shows a detailed description of the primary collision factor, type of accident, and number of injuries reported at each of these three locations. The most common factor at the intersections of Seal Beach Boulevard at the I-405 southbound on/off ramps and Seal Beach Boulevard at Lampson Avenue was unsafe speed. Construction of improvements at the intersection of Seal Beach Boulevard and the I-405 southbound on/off ramps were recently completed in 2014. The effect of these improvements helped reduce the number of accidents at this intersection from six in 2013 to only three in the first 11 months of 2014. Improvements south of the intersection of Seal Beach Boulevard and Lampson Avenue were recently constructed in 2014. The improvements included additional northbound and southbound through lanes along Seal Beach Boulevard over the I-405 freeway. The effects of these improvements not only improved the LOS, but could also reduce the number of accidents at this intersection. No accidents were reported in the first 11 months of 2014. The intersection of Seal Beach Boulevard and St. Cloud Drive experienced five accidents in 2013 and only four accidents within the first 11 months of 2014. Based on the operational analysis provided in this report, this intersection operates at an acceptable LOS, and no additional improvements are recommended at this time. It is recommended that the City continue to monitor the operation and safety of all intersections and roadway segments within its jurisdiction and make the necessary improvements to reduce potential accidents in the future. HEALTH CLUB The proposed project will consist of 37,000 sf of health/fitness club uses and is bounded on the north by Rossmoor Center Drive, on the west by West Road, and on the east by Sprouts Farmers Market. The project site is located in the northwest parking lot of The Shops at Rossmoor retail center. It should be noted that this parking lot serves as an employee/overflow lot behind all of the existing adjacent stores and does not provide direct access to Sprouts, Marshalls or PetsMart. The main access points to the project site are located on either side of the proposed building at West Road and the existing driveway along the south side of Rossmoor Center Drive west of Sprouts Farmers Market. Trip Generation and Distribution The generation and distribution of trips associated with the proposed project site are discussed below.

Trip generation for the proposed project is calculated based on rates contained in the Institute of Transportation Engineers’ (ITE) Trip Generation (Ninth Edition), which is a standard reference used by jurisdictions throughout the country for estimating the trip generation potential of new developments. The project is classified as Health/Fitness club use (ITE Land Use 492). The project’s potential trip generation was calculated using the average rates (per 1,000 sf). As indicated in Table E, the proposed project is estimated to generate 1,218 daily trips, 52 weekday a.m. peak hour trips, 131 weekday p.m. peak hour trips, and 103 Saturday mid-day peak hour trips.

ADT = average daily traffic TSF = thousand square feet Trip Distribution and Trip Assignment. The project trips were distributed throughout the study area using information from the County’s current travel demand model (Orange County Transportation Analysis Model [OCTAM]). Using the travel demand model, a process known as “select zone assignment” is applied to distribute and assign trips from a specific zone through the circulation network to an origin. The travel demand model goes through several iterations to develop the most likely distribution pattern that takes into account several factors such as the shortest distance between origin and destination, availability of capacity, and type of uses, etc., before assigning the trips. The trips were distributed manually based on a select zone assignment from the OCTAM traffic model. Based on the select zone assignments and further manual refinements, the project traffic is distributed as follows: 43 percent of traffic will travel north along Seal Beach Boulevard, 49 percent will travel south along Seal Beach Boulevard, of which 3 percent will travel west on the State Route 22 (SR-22) freeway into Long Beach, 12 percent will travel east along Lampson Avenue, 10 percent northwest along northbound I-405, 15 percent southeast along the I-405 southbound, and the remaining 9 percent would continue to travel south along Seal Beach Boulevard. A total of 8 percent will have destinations within close proximity to the retail site. Figures 6 and 7 illustrate the health club trip assignment for weekday and weekend conditions based on the trip generation and the trip distribution identified above. UNOCCUPIED SPACE WITHIN THE SHOPS AT ROSSMOOR In order to evaluate the adjacent Shops at Rossmoor retail center at full occupancy, traffic from the unoccupied space in the northern part of the retail center has been developed.

The location of the unoccupied space in relation to the rest of the retail center is shown in Figure 8. Retail Trip Generation and Distribution The generation and distribution of trips associated with this unoccupied space are discussed below. Trip Generation. Trip generation for the unoccupied space is calculated based on rates contained in the Institute of Transportation Engineers’ (ITE) Trip Generation (Ninth Edition), which is a standard reference used by jurisdictions throughout the country for estimating the trip generation potential of new developments. The unoccupied space is classified as part of the shopping center use (ITE Land Use 820). The potential trip generation was calculated using the average rates (per 1,000 sf) as opposed to the fitted curve equation as the equations are inappropriate for the size of the unoccupied space and would result in an unrealistic estimation of potential trips. As indicated in Table F, the unoccupied space is estimated to generate 102 daily trips, 2 weekday a.m. peak hour trips, 9 weekday p.m. peak hour trips, and 12 Saturday mid-day peak hour trips.

Trip Distribution and Trip Assignment. The new retail trips were distributed throughout the study area using the same information from the County’s current travel demand model (Orange County Transportation Analysis Model [OCTAM]) that was utilized for the proposed project. Figures 9 and 10 illustrate the trip assignment for weekday and weekend conditions based on the trip generation and the trip distribution identified previously. Trips generated by the unoccupied parcel were added to the base traffic volumes to develop “with Full Occupancy” traffic volumes.

The trip assignment of the unoccupied portion of the retail center was added to the Existing (2014) counts to develop the volumes for the Existing (2014) with Full Occupancy conditions. Figures 11 and 12 show the Existing (2014) with Full Occupancy condition peak-hour volumes at study area intersections for weekday and weekend conditions. A summary of Existing (2014) with Full Occupancy conditions LOS at study area intersections and roadway segments are presented in Tables G and H, respectively. The LOS worksheets for Existing (2014) with Full Occupancy conditions are included in Appendix D. As the tables indicate, all study area intersections and roadway segments are anticipated to operate at satisfactory LOS (LOS D or better). EXISTING (2014) WITH FULL OCCUPANCY PLUS PROJECT CONDITIONS In order to identify any potential project impacts to traffic and circulation, project traffic was added to Existing (2014) with Full Occupancy traffic. The resulting Existing (2014) with Full Occupancy plus Project conditions weekday a.m., p.m., and weekend mid-day peak-hour traffic volumes are shown on Figures 13 and 14, respectively. A summary of Existing (2014) with Full Occupancy plus Project LOS for study area intersections and roadway segments is presented in Tables I and J, respectively. The LOS worksheets for Existing (2014) with Full Occupancy plus Project conditions are included in Appendix E. As the tables indicate, all study area intersections and roadway segments are anticipated to continue to operate at satisfactory LOS (LOS D or better) with the addition of project traffic. PROJECT COMPLETION YEAR (2016) WITH FULL OCCUPANCY CONDITIONS According to the project applicant, the proposed project will be completed in 2016. In order to present a near-term 2016 traffic condition, an ambient growth rate of 0.5 percent per year was added to existing traffic volumes along with traffic from the unoccupied parcel within The Shops at Rossmoor. This growth rate was reached through consultation with City staff. It should be noted that City staff also provided information on one nearby cumulative development of a new car wash within the Mobil gas station on the northeast corner of Seal Beach Boulevard and Rossmoor Center Way/Plymouth Drive. Additional traffic from this development was not included in this analysis as the traffic counts taken in November 2014 have taken into account the existing car wash within the Mobil gas station. The resulting Project Completion Year (2016) with Full Occupancy conditions weekday a.m., p.m., and weekend mid-day peak hour traffic volumes are shown on Figures 15 and 16, respectively. 424 / 485 533 / 534 0 / 6 15 / 90 47 / 42 80 / 13 600 / 528 7 / 30 3 / 39 540 / 315 304 / 172 491 / 387 59 / 189 14 / 125 92 / 169 7 / 64 103 / 107 5 / 82 17 / 48 5 / 56 3 / 1 2 / 38 6 / 12 11 / 88 571 / 351 21 / 205 1Seal Beach Blvd/I-405 SB Ramps2Seal Beach Blvd/I-405NB Ramps3Seal Beach Blvd/Lampson Av 4Seal Beach Blvd/Saint Cloud Dr5Seal Beach Blvd/Town Center Dr 40 / 11 22 / 15 2 / 11 44 / 81 7 / 2 25 / 9 366 / 419 0 / 8 40 / 45 12 / 10 51 / 55 43 / 44 1 / 0 13 / 29 89 / 188 276 / 161 597 / 429 58 / 22 93 / 35 2 / 1 13 / 10 0 / 4 6 / 4 73 / 42 86 / 124 103 / 62 129 / 54 79 / 47 6Seal Beach Blvd/Rossmoor Center Wy7Seal Beach Blvd/Bradbury Rd 8Yellowtail Dr/Saint Cloud Dr 9Montecito Rd/Copa De Oro Dr10Montecito Rd/Rossmoor Center Wy 146 / 75 39 / 81 29 / 22 96 / 146 99 / 164 52 / 93 51 / 246 159 / 150 4 / 21 7 / 21 51 / 148 28 / 76 10 / 3 122 / 91 127 / 101 35 / 27 29 / 15 12 / 17 104 / 81 1 / 3 15 / 21 11Montecito Rd/Bradbury Rd 12West Rd/Rossmoor Center Wy13Project Dwy/Rossmoor Center Wy14Internal Drwy/Rossmoor Center Wy15Internal Dwy/Town Center Dr FIGURE 11 Legend 123 / 456 AM / PM Volume Health Club within The Shops at Rossmoor Existing (2014) with Full Occupancy Peak Hour Volumes (AM/PM) 12 4 1 / 1 5 3 5 15 0 7 / 1 4 1 5 36 7 / 6 4 0 12 7 6 / 1 4 4 0 20 6 / 3 6 0 80 / 1 3 6 63 / 1 6 4 13 4 6 / 1 5 3 3 26 / 3 5 13 1 1 / 1 2 9 6 19 / 9 1 45 0 / 3 3 5 13 1 2 / 1 2 6 0 29 1 / 2 0 9 40 / 8 0 13 9 2 / 1 5 1 2 17 0 / 1 7 5 20 / 6 9 28 7 / 2 0 1 14 3 2 / 1 5 0 2 4 / 2 7 14 1 / 1 2 1 13 2 6 / 1 6 4 5 15 / 2 3 3 / 5 0 / 2 4 / 1 0 22 / 4 8 5 / 2 13 7 / 1 1 3 91 / 3 9 19 1 / 1 4 1 23 / 3 8 80 / 4 5 52 / 4 1 10 8 / 4 5 16 9 / 1 6 3 2 / 7 13 6 / 9 5 22 4 / 1 0 3 5 / 1 1 2 / 2 5 4 / 5 1 23 / 3 4 14 / 3 7 62 / 6 5 1 / 3 12 / 1 9 32 / 2 8 4 9 / 4 2 11 / 3 8 34 / 1 6 6 12 / 4 7 11 / 6 3 82 / 3 8 21 3 / 1 7 5 32 / 4 9 15 / 8 6 15 1 2 / 1 3 8 9 36 2 / 3 4 8 14 5 9 / 1 4 6 8 55 / 1 5 3 23 / 1 5 4 12 8 / 3 5 2 43 4 / 4 6 1 12 / 1 7 81 6 / 1 0 2 5 4 / 1 4 15 / 1 0 9 24 3 / 3 8 5 10 8 / 4 4 97 6 / 1 2 6 1 88 / 1 5 2 11 1 0 / 9 1 2 P:\MPA1401\Figures\Fig-11 Exist Full Occ AM PM.xls\Figure (9/30/2015) 498 564 9 98 25 5 469 23 84 461 300 290 184 181 163 7 104 124 37 12 1 75 17 8 332 209 1Seal Beach Blvd/I-405 SB Ramps2Seal Beach Blvd/I-405NB Ramps3Seal Beach Blvd/Lampson Av4Seal Beach Blvd/Saint Cloud Dr5Seal Beach Blvd/Town Center Dr 19 6 7 84 3 8 395 7 32 11 58 38 3 28 214 136 383 25 25 12 4 3 6 40 191 81 42 26 6Seal Beach Blvd/Rossmoor Center Wy7Seal Beach Blvd/Bradbury Rd8Yellowtail Dr/Saint Cloud Dr9Montecito Rd/Copa De Oro Dr10Montecito Rd/Rossmoor Center Wy 47 89 18 115 123 86 414 103 12 40 231 103 3 100 107 21 12 23 2 88 6 36 11Montecito Rd/Bradbury Rd12West Rd/Rossmoor Center Wy13Project Dwy/Rossmoor Center Wy14Internal Drwy/Rossmoor Center Wy15Internal Dwy/Town Center Dr FIGURE 12 Legend 123 Saturday Volume Health Club within The Shops at Rossmoor Existing (2014) with Full Occupancy Peak Hour Volumes (Saturday) 89 4 13 2 24 5 39 7 21 91 3 16 15 8 32 924 12 5 5 13 5 11 3 8 31 9 15 2 6 16 6 27 8 20 14 9 56 32 1 52 60 21 7 61 8441 26 46 97 4 395 10 7 10 0 1029 3 87 46 14 1 37562654 17 9 2 937 14 0 4 10 5 61 19 5 13 1 6 46 81 14 7 8 13 4 17 9 20 9 13 5 0 34 10 4 3 10 5 27 7 11 9 6 23 1 62 13 2 9 14 2 2 42 6 15 3 6 28 7 P:\MPA1401\Figures\Fig-12 Exist Full Occ Sat.xls\Figure (9/30/2015) LS A A S S O C I A T E S , I N C .

Project Completion Year (2016) with Full Occupancy plus Project conditions weekday a.m., p.m., and weekend mid-day peak hour traffic volumes are shown on Figures 17 and 18, respectively. A summary of Project Completion Year (2016) with Full Occupancy LOS for study area intersections and roadway segments is presented in Tables K and L, respectively. LOS for study area intersections and roadway segments associated with the addition of the proposed project are presented in Tables M and N, respectively. As shown on the tables, all study area intersections and roadway segments are anticipated to operate at satisfactory LOS (LOS D or better) under Project Completion Year (2016) with Full Occupancy conditions, without and with the proposed project. The LOS worksheets for Project Completion Year (2016) with Full Occupancy without and with Project conditions are included in Appendices F and G, respectively. FUTURE (2035) GENERAL PLAN BUILDOUT CONDITIONS Traffic conditions for the future long-range condition, corresponding to the buildout of the City’s General Plan, were analyzed in the study. The traffic volumes for Future (2035) General Plan Buildout traffic conditions were developed based on an annual growth rate applied to the Existing (2014) weekday a.m., p.m., and weekend peak-hour traffic volumes at study intersections and roadway segments to represent a 21-year horizon. To develop the Future (2035) General Plan Buildout baseline volumes, LSA estimated the annual growth rate of 0.2 percent per year based on the growth along Seal Beach Boulevard using the OCTAM traffic model. However, based on discussions with City staff, a growth rate of 0.5 percent per year was applied over the next 21 years to provide a conservative traffic analysis. To account for the fully occupied retail center, the trip assignment generated earlier for the unoccupied portion was manually added to the Future (2035) General Plan Buildout traffic volumes to develop the volumes for the Future (2035) General Plan Buildout with Full Occupancy condition. The LOS at the study area intersections and roadway segments were identified based on this data. Figures 19 and 20 show the Future (2035) General Plan Buildout with Full Occupancy peak hour volumes at the study area intersections for weekday and weekend conditions, respectively. Intersection turning movement volumes resulting from the addition of the proposed project are shown on Figures 21 and 22 for weekday and weekend conditions, respectively. A summary of Future (2035) General Plan Buildout with Full Occupancy LOS for study area intersections and roadway segments is presented in Tables O and P, respectively. The LOS for study area intersections and roadway segments associated with the inclusion of the proposed project are presented in Tables Q and R, respectively. 432 / 500 542 / 550 0 / 6 15 / 91 47 / 42 81 / 13 609 / 542 7 / 30 3 / 39 545 / 318 307 / 174 496 / 391 60 / 191 14 / 126 93 / 171 7 / 65 104 / 108 5 / 83 17 / 48 5 / 57 3 / 1 2 / 38 6 / 12 11 / 89 578 / 358 21 / 207 1Seal Beach Blvd/I-405 SB Ramps2Seal Beach Blvd/I-405NB Ramps3Seal Beach Blvd/Lampson Av4Seal Beach Blvd/Saint Cloud Dr5Seal Beach Blvd/Town Center Dr 40 / 11 22 / 15 2 / 11 45 / 84 7 / 2 25 / 9 371 / 427 1 / 9 41 / 47 12 / 10 52 / 56 43 / 44 1 / 1 14 / 31 101 / 215 279 / 163 604 / 436 59 / 22 94 / 35 2 / 1 13 / 10 0 / 4 7 / 6 75 / 44 98 / 150 104 / 63 130 / 55 80 / 47 6Seal Beach Blvd/Rossmoor Center Wy7Seal Beach Blvd/Bradbury Rd8Yellowtail Dr/Saint Cloud Dr9Montecito Rd/Copa De Oro Dr10Montecito Rd/Rossmoor Center Wy 147 / 76 39 / 82 29 / 22 97 / 147 100 / 166 76 / 159 52 / 248 161 / 152 4 / 21 30 / 86 52 / 149 28 / 77 10 / 3 123 / 92 128 / 102 35 / 27 29 / 15 15 / 24 128 / 132 1 / 3 15 / 21 11Montecito Rd/Bradbury Rd12West Rd/Rossmoor Center Wy13Project Dwy/Rossmoor Center Wy14Internal Drwy/Rossmoor Center Wy15Internal Dwy/Town Center Dr FIGURE 17 Legend 123 / 456 AM / PM Volume Health Club within The Shops at Rossmoor Project Completion Year (2016) with Full Occupancy plus Project Peak Hour Volumes (AM/PM) 11 2 3 / 9 2 7 89 / 1 5 4 12 9 / 3 5 6 44 2 / 4 7 4 12 / 1 7 82 6 / 1 0 4 2 4 / 1 4 15 / 1 1 0 24 5 / 3 8 9 10 9 / 4 4 99 2 / 1 2 9 0 15 / 8 7 15 3 9 / 1 4 3 6 36 7 / 3 5 5 14 8 6 / 1 5 1 6 56 / 1 5 5 23 / 1 5 6 83 / 3 8 21 5 / 1 7 7 33 / 5 1 32 / 2 8 7 9 / 4 2 11 / 3 8 34 / 1 6 8 12 / 4 7 11 / 6 4 4 / 5 2 23 / 3 4 14 / 3 7 63 / 6 6 1 / 3 35 / 6 9 2 / 7 13 8 / 9 8 22 6 / 1 0 4 5 / 1 1 5 / 3 1 5 / 2 13 9 / 1 1 6 92 / 3 9 19 3 / 1 4 2 24 / 4 1 81 / 4 5 53 / 4 1 10 9 / 4 5 17 2 / 1 6 8 0 / 3 4 / 1 0 22 / 4 8 14 1 8 / 1 5 5 2 17 2 / 1 7 7 20 / 7 0 29 1 / 2 0 5 14 4 6 / 1 5 1 7 4 / 2 7 14 2 / 1 2 2 13 5 1 / 1 6 9 3 15 / 2 3 3 / 5 92 / 1 7 0 75 / 1 9 8 13 5 9 / 1 5 4 8 26 / 3 5 13 3 6 / 1 3 3 5 19 / 9 2 45 6 / 3 4 0 13 3 1 / 1 2 8 7 29 7 / 2 1 7 40 / 8 1 12 6 5 / 1 5 7 6 15 3 2 / 1 4 5 0 37 4 / 6 5 2 12 9 9 / 1 4 8 2 20 8 / 3 6 4 P:\MPA1401\Figures\Fig-17 OY WP AM PM.xls\Figure (9/30/2015) 509 577 9 99 25 5 479 23 85 466 303 293 186 183 165 7 105 125 37 12 1 76 17 8 338 211 1Seal Beach Blvd/I-405 SB Ramps2Seal Beach Blvd/I-405NB Ramps3Seal Beach Blvd/Lampson Av4Seal Beach Blvd/Saint Cloud Dr5Seal Beach Blvd/Town Center Dr 19 6 7 87 3 8 401 8 34 11 59 38 4 30 241 137 390 25 25 12 4 3 7 42 218 82 42 26 6Seal Beach Blvd/Rossmoor Center Wy7Seal Beach Blvd/Bradbury Rd8Yellowtail Dr/Saint Cloud Dr9Montecito Rd/Copa De Oro Dr10Montecito Rd/Rossmoor Center Wy 47 90 18 116 124 128 418 104 12 81 233 104 3 101 108 21 12 28 2 139 6 36 11Montecito Rd/Bradbury Rd12West Rd/Rossmoor Center Wy13Project Dwy/Rossmoor Center Wy14Internal Drwy/Rossmoor Center Wy15Internal Dwy/Town Center Dr FIGURE 18 Legend 123 Saturday Volume Health Club within The Shops at Rossmoor Project Completion Year (2016) with Full Occupancy plus Project Peak Hour Volumes (Saturday) 90 8 13 3 24 7 40 9 21 92 6 16 16 0 33 224 12 7 9 13 6 11 7 0 32 4 15 6 2 16 8 28 1 20 15 0 58 32 4 53 61 21 9 62 8541 26 46 98 4 895 11 0 10 1 1035 3 89 46 14 2 39572655 18 3 2 937 14 4 2 10 6 62 19 9 13 2 9 46 82 15 1 3 13 4 20 2 23 1 13 6 3 34 10 7 8 10 6 28 2 12 2 2 23 8 63 13 6 7 14 5 7 43 7 15 6 9 29 0 P:\MPA1401\Figures\Fig-18 OY WP Sat.xls\Figure (9/30/2015) LS A A S S O C I A T E S , I N C .

The LOS worksheets for Future (2035) General Plan Buildout with Full Occupancy without and with Project conditions are included in Appendices H and I, respectively. As shown on Table Q, the addition of project traffic at the intersection of Seal Beach Boulevard and Rossmoor Center Way results in an ICU increase that exceeds the City’s threshold of significance by 0.004 during the weekday p.m. peak hour. It should be noted this intersection is anticipated to operate at an acceptable LOS C or better under all peak hours in the Future (2035) General Plan Buildout with Full Occupancy with Project conditions. As all study area intersections and roadway facilities are anticipated to operate at satisfactory LOS from Existing (2014) to Future (2035) General Plan Buildout with Full Occupancy plus Project traffic conditions, operational improvements aimed at alleviating LOS deficiencies are not warranted and have not been recommended. It is recommended that the project mitigate its significant contribution of traffic at the intersection of Seal Beach Boulevard and Rossmoor Center Way through a fair share contribution towards improvements to alleviate existing queuing deficiencies as described in the following section. ON-SITE CIRCULATION This section presents the results of the site access assessment conducted for Existing (2014) and Existing (2014) with Full Occupancy plus Project conditions. As presented previously in this report, both project driveways and site adjacent intersections are anticipated to operate at satisfactory LOS for all analysis scenarios. As part of the site access assessment, existing and potential turn-pocket queuing issues at site access points and site adjacent intersections were analyzed using the SimTraffic (Version 8.0) software. SimTraffic is an analysis software that provides a microscopic model that more accurately simulates real world conditions as compared to macroscopic analysis tools such as Traffix. SimTraffic tracks and collects measures of effectiveness for each vehicle in a traffic system during a simulation. Due to variability that arises from simulations of this nature, multiple simulation runs for each analysis scenario have been averaged in order to draw representative queuing results. This method more accurately measures the full impact of queuing and blocking of traffic. Queuing results for Existing (2014) with Full Occupancy without and with Project traffic conditions are shown on Table S. As shown on Table S, all existing peak-hour queues at site access points and site-adjacent intersections are anticipated to be sufficiently stored by existing facilities with the exception of the northbound left-turn pocket at the intersection of Seal Beach Boulevard and Rossmoor Center Way. The existing weekday a.m., p.m., and weekend mid-day 95th percentile peak- hour queues extend past the storage provided by the existing northbound left-turn pocket. The northbound left-turn pocket currently provides 80 feet (ft) of storage with a 100 ft transition. However, as shown on Table S, a potential queue of 168 ft resulting from 179 existing northbound left-turning vehicles (without the project) during the weekend (Saturday) mid-day peak hour could spill back into the adjacent through lane.

It should be noted that anticipated queue lengths are not directly correlated to their associated volumes as queuing for a given movement is also dependent on traffic signal operations. This existing queuing issue is anticipated to continue into future analysis scenarios. All other Existing (2014) with Full Occupancy plus Project peak-hour queues at site access points and site-adjacent intersections are anticipated to be sufficiently stored by existing facilities. SimTraffic queuing worksheets for both Existing (2014) and Existing (2014) with Full Occupancy plus Project conditions are provided in Appendix J. The existing northbound left-turn pocket at the intersection of Seal Beach Boulevard and Rossmoor Center Way is bound by the landscaped median along Seal Beach Boulevard and a southbound left- turn pocket that provides access to the Target shopping center to the southeast of this intersection. As such, any physical improvements to this northbound left-turn pocket would require some vacation of the landscaped median and could not extend past the existing southbound left-turn pocket to the south. Operational and physical improvements required to provide adequate turn-pocket storage are discussed in the Recommended Improvements section of this report. PARKING This parking study reviews parking supply and demand for the proposed health club within the Shops at Rossmoor. The proposed project will generate future parking demand in excess of existing parking demand while reducing the existing parking supply. Although the Shops at Rossmoor retail center is private property, some residents of adjacent condominium communities utilize retail center parking spaces for their vehicles when not conducting business at the retail center. This analysis investigates whether the reduced parking supply can adequately meet future parking demand or whether increased enforcement of parking policy will be necessary to ensure adequate parking supply for retail and health club patrons. Existing Conditions The proposed health club will be built in an existing parking lot within the Shops at Rossmoor. The affected parking lots are shown on Figure 23 and divided into two zones. The number and type of parking spaces in each zone are also displayed on Figure 23. Parking accumulation counts were conducted by NDS at the shopping center on a typical weekday, Thursday, November 13, 2014, and again on a typical weekend, Saturday, November 15, 2014. As shown on Tables T and U, and Figure 23, adequate parking is provided in Parking Zones 1 and 2 to accommodate the existing peak weekday and weekend parking demand.

Seal Beach Municipal Code (SBMC) Section 11.4.20 establishes required parking for all developments within the City. SBMC Table 11.4.20.015.A.1 states that gyms and fitness studios greater than 20,000 sf must provide 1 parking space per 300 sf of development. Per the SBMC, 124 parking stalls are required to serve the proposed 37,000 sf health club. In addition, development of the project would result in a loss of 40 parking spaces from Parking Zones 1 and 2, bringing the total parking supply of Zones 1 and 2 from 445 to 405 stalls. Demand for these spaces would vary throughout the day. The Urban Land Institute (ULI) has collected data on the variation in parking demand for health clubs by time of day and has published that data in Shared Parking (Second Edition). Table V displays the anticipated variation in weekday parking demand generated by the proposed project and adds that to the observed existing parking demand to determine the anticipated total future parking demand. This total is compared to the future parking supply of 405 spaces to determine the number of spaces remaining. Table W repeats this process for weekend parking demand. Figure 24 illustrates the future parking supply and peak parking demand by zone. Seventeen of the stalls in Zone 2 are reserved for the Farmers and Merchants Bank building, per the Fifth Amendment to Declaration of Covenants, Conditions and Restrictions and Grant of Easements (Effective March 31, 2014). Tables V and W have included these 17 reserved parking stalls as part of the future parking demand. As shown on Tables V and W, sufficient parking will be provided in the weekday and weekend by the combination of Parking Zones 1 and 2 to accommodate future demand which includes buildout of the retail center and the proposed project. 40%507417141405264 70%877817182405223 70%878517189405216 80%9910417220405185 60%749917190405215 70%8710617210405195 70%8710417208405197 70%8710017204405201 80%999017206405199 90%1128817217405188 100%1248817229405176 90%1129217221405184 80%999617212405193 70%879817202405203 35%439017150405255 1 2 3 10:00 p.m. Health Club Time-of-Day Factors for Weekdays, Shared Parking Second Edition, Urban Land Institute 5:00 p.m. 6:00 p.m. 7:00 p.m. 8:00 p.m. 9:00 p.m. 8:00 a.m. 9:00 a.m. 10:00 a.m. 11:00 a.m. 17 stalls within Zone 2 have been reserved for the Farmers & Merchants bank building in the Shops at Rossmoor per the Fifth Amendment to Declaration of Covenants, Conditions and Restrictions and Grant of Easements. 12:00 p.m. Farmers & Merchant Bank3 Table V: Future Weekday Parking Demand Typical Parking Demand1 Existing Demand Future Total Parking Supply Remaining Spaces LA Fitness 1242 The Seal Beach Municipal Code (SBMC) requires 1 space per 300 square feet (sf) of gym and fitness studios greater than 20,000 sf; LA Fitness is proposed to be 37,000 sf 1:00 p.m. 2:00 p.m. 3:00 p.m. 4:00 p.m. 35%439117151405254 50%629917178405227 35%4311017170405235 50%6211917198405207 50%6212217201405204 30%3714217196405209 25%3115317201405204 30%3714817202405203 55%6812517210405195 100%12411917260405145 95%11811817253405152 60%7410717198405207 30%3710517159405246 10%129017119405286 1%19217110405295 1 2 3 10:00 p.m. Health Club Time-of-Day Factors for Weekends, Shared Parking Second Edition, Urban Land Institute 5:00 p.m. 6:00 p.m. 7:00 p.m. 8:00 p.m. 9:00 p.m. 8:00 a.m. 9:00 a.m. 10:00 a.m. 11:00 a.m. 17 stalls within Zone 2 have been reserved for the Farmers & Merchants bank building in the Shops at Rossmoor per the Fifth Amendment to Declaration of Covenants, Conditions and Restrictions and Grant of Easements.

Improvements aimed at alleviating existing peak-hour queuing deficiencies at the site-adjacent intersection of Seal Beach Boulevard and Rossmoor Center Way are recommended. The northbound left-turn movement is currently experiencing queues that could extend past the existing left-turn pocket during periods of peak demand. The provision of dual left-turn lanes is one possible solution to long queues. However, if an unequal utilization of the left-turn lanes were probable, the effectiveness of providing two lanes would be greatly diminished. In addition, right-of-way may be necessary to implement dual left-turn lanes. In these circumstances, extending the queue available to the single lane may be a better option. As shown on Table S, the northbound left-turn pocket would require a storage length of approximately 168 ft (an extension of 88 ft) to accommodate Existing (2014) with Full Occupancy peak-hour queues and a storage length of approximately 182 ft (an extension of 102 ft) to accommodate Existing (2014) with Full Occupancy plus Project peak-hour queues. As noted previously and illustrated on Figure 25, the existing landscaped median along Seal Beach Boulevard would require modification and possibly vacation in order to provide the recommended storage length. As shown on Figure 25, a storage length of 205 ft (an extension of 125 ft) would not disrupt the existing southbound left-turn pocket providing access to the adjacent Target shopping center, but may create a situation where the two adjacent left-turn pockets would effectively be “back to back.” Additionally, traffic signal phasing modifications can be made in order to help alleviate the existing and anticipated queuing issue. One such modification is to provide both a “lead” and “lag” phase for the northbound left-turn movement. This would entail providing phasing for this movement during both the beginning and end of the adjacent northbound through movement, effectively providing two northbound left-turn phases per cycle. As shown on Table X, this traffic signal modification can help reduce the peak-hour queues but not enough to eliminate the need to provide additional queuing storage. It should be noted that this traffic signal modification can be accommodated while maintaining acceptable intersection LOS per the HCM methodology. Queuing worksheets reflecting the described traffic signal phasing modification at the intersection of Seal Beach Boulevard and Rossmoor Center Way for Existing (2014) with Full Occupancy without and with Project conditions are included in Appendix L. In an effort to determine the extent of the proposed project’s contribution to this existing and future queuing deficiency, the percentage of northbound left-turning vehicles attributable to the project has been calculated. The following table, Table Y, details the project’s percentage of northbound left- turning vehicles under Existing (2014) with Full Occupancy plus Project for each of the three peak hours.

The study included analysis of intersections and roadway segments along Seal Beach Boulevard and local access roads adjacent to the proposed project. The LOS at 15 intersections and 11 roadway segments within the study area for seven scenarios were analyzed and physical and/or operational improvements were not recommended as all facilities were found to meet the City’s LOS standards. A queuing analysis of site-access points and site-adjacent intersections found that all peak-hour queues are anticipated to be sufficiently stored by existing facilities with the exception of the northbound left-turn pocket at the intersection of Seal Beach Boulevard and Rossmoor Center Way. The extension of the existing northbound left-turn pocket from 80 ft to 205 ft has been recommended in order to alleviate this existing and anticipated queuing deficiency. It is recommended that the project contribute a fair share percentage of 20% of the total cost of improving this northbound left- turn pocket. A parking assessment was conducted to evaluate the adequacy of the proposed parking supply in meeting future parking demand. Based on this assessment, the proposed parking supply exceeds the anticipated parking demand. LSA ASSOCIATES, INC.
