BACKGROUND: As part of the five-year Capital Improvement Program, staff recommended the replacement of the swimming pool and related facilities currently located at McGaugh School. The City Council directed staff to provide an assessment of the existing facility as well as estimated renovation costs and replacement costs. Rowley International, Inc., an aquatic design, engineering and consulting firm, was retained to conduct the study. Their report is attached for your perusal. Mr. Greg Cannon of Rowley International, Inc. will be present at the meeting to present the report and answer any questions. The report suggests that while the existing facilities could be renovated, the City may be better served by replacing the existing facilities. This would be true especially if the needs of the City have changed since the original facility was designed. Further, the report documents'deviations from the current building code and health and safety code related to public swimming pools which need to be addressed. Separately, the Los Alamitos Unified School District has retained a soils engineer to study saturated soil conditions near the existing pool. This report should be finished by November 1st. On September 24, 2008 the Recreation Commission was presented with the Rowley feasibility study for the McGaugh swimming pool. Commission members Agenda Item ~/ Page 2 stated that they feel swimming is an important skill for the youth of Seal Beach to learn. It is their philosophy that with the proximity to the beach it is a matter of public safely that all children are provided with an opportunity to learn how to swim. They feel the swimming pool is a valuable asset to the community. With a vote of 4 to 0 the commission recommended that the City pursue a plan of replacing the existing pool as opposed to renovating the present pool. The commission also commended the drafting of the report as a valuable too to reviewing the issue. If there is interest in addressing the issues identified by the study at the McGaugh Swimming Pool, staff recommends the City Council refer the matter to the Recreation Commission with direction as to the further specific issues to be addressed by the Commission. Issues that the City Council may wish the Commission to review include but are not limited to: • Master planning of recreation regarding the McGaugh site. • Location of a new facility at McGaugh or another location • Activities the facility will need to accommodate such as recreation needs, swim team, adult swim, water polo, diving, swim lessons, tot pool. • Operational issues and expenses • Funding FINANCIAL IMPACT: There are no direct financial impacts associated with this agenda item. RECOMMENDATION: It is respectfully recommended that the City Council receive and file the Feasibility Study for the Mc Gaugh Swimming Pool RenovatioNReplacement and refer the matter to the Recreation Commission for further study.

INTRODUCTION This report is Rowley International Ines analysis of the Seal Beach Pool Facility, recommendations for repairs, renovations to meet current codes, and to provide a modern, efficient, enduring aquatic facility. The pros and cons of repairing and renovating the existing pools versus replacing the pool entirely have been considered. This report will conclude that the best recommendation is to demolish the existing pool and replace it with a new, state-of-the-art outdoor pool that is configured to meet the year-round fitness, recreational, and athletic aquatics needs of the City of Seal Beach. B. EXISTING FACILITY The facility was examined on July 9, 2008 by Greg Cannon and Ron Bravo of Rowley International Inc. During this site visit, the general condition and operational characteristics of the swimming pools and associated mechanical equipment were inspected and discussed. The swimming pools were full of water with all of the existing equipment in full operation. Dimensions of the swimming pools were measured and elevations were observed with regard to the water level at the gutter lip. The Seal Beach Aquatic Facility serves as a community aquatics facility. The facility consists of: (1) the L-shaped 25-yard x 25-meter competition/lap pool and (2) the 20' x 30' shallow children's pool. The lap pool measures 75'-2" x 45' (25-yard section) and 82' x 40' (25-meter section) with a depth ranging from 3'-6" to 12'-0". Each L section consists of 6 competitive swimming lanes. The competition pool is equipped with a 1-meter diving board. The children's pool measures 20' x 30' with depths ranging from 2'/i to 3'. The children's pool has been resurfaced with a fiberglass lining. The two pools share a mechanical equipment room, equipment for filtration, heating, and chemical treatment. The equipment is remotely located to the east of the complex in an indoor mechanical space adjacent to the middle school gymnasium. The swimming pools appear to be sound; however, the pool operator states that there is significant water loss which seems to be more significant when swimmers are present in the pools. Presently the pools are used throughout the year by the City Parks and Recreation Aquatics Program. 1. POOL SHELLS The original pool shells on both pools appear to be constructed of cast-in-place concrete floors with shotcrete or gunite walls. Page 2 ~ o UV l e y l n t e r n a t i o n a l Inc Seal Beach Feasibility Study September 2008 B. EXISTING FACILITY (continued) Visual inspection indicates that the shell of the lap pool was constructed with expansion joints in the floors and walls. These joints are typically a point of interest in any pool experiencing water loss problems. The shells appear to be structurally sound with no major cracking or structural problems that would require immediate replacement. However, it must be stated that these observations were made when the existing pools were filled with water and in full operation. The children's pool was refinished with fiberglass. Presumably, the original plaster surfaces broke down, necessitating the resurfacing procedures. A fiberglass pool finish offers both advantages and disadvantages. A fiberglass finish can be done quickly and inexpensively; this covers up and seals broken down plaster. Unfortunately, the cover-up feature of the fiberglass also masks the damage that may be hiding underneath. The fiberglass appears to be sound with small cracks in the finish. Only a thorough examination of the surface when the pool is empty can accurately reveal the condition of the fiberglass. The lap pool features relatively small tiled concrete gutters. This gutter system can be classified as a "scum gutter". It is much smaller than the gutters designed for today's competition pools. These gutters are typically suited for a recreational/competition pool application where little emphasis is placed on the quality of water in the pool. This scum gutter is not typically well suited for serious competition-type pools in which performance need to be maximized. When properly adjusted, this scum gutter should provide surface skimming from the entire perimeter of the pool. The gutter measures approximately 4" wide by 5" deep around the entire pool perimeter with gutter outlets approximately every 14 to 15 feet. The gutter systems appear to be capable of proper function. The system is currently surface skimming around the pool. The functions of these gutter systems are made less effective due to the fact that both pools operate through a common water circulation system. This circulation system violates current State Health Codes. The children's pool uses a skimmer system for surface skimming rather than a gutter system. The lap pool has 3 main drains located at the floor of the pool at its deepest point. The lap pool and children's pool are equipped with wet-niche underwater lights. The lap pool lights are located 18" below the water line and appear to have been replaced since the original construction. At the time of the replacement, it appears that all aspects of the National Electric Code have been met with respect to swimming pool underwater lights. Operation of the pool lights was not verified at the time of the RI's facility inspection. Page 3 Rowney International Inc B. EXISTING FACILITY (continued) Visual inspection indicates that both pools were built with a fair amount of the as was customary of the pools built around 1964. The entire gutter system was finished in mosaic tiles. There are the depth markers around the perimeter of both pool decks. However, the visibility of the the depth markers is poor due to the age of the tile. 2. PIPING Seal Beach Feasibility Study September 2008 's- a - ~~zFr tt ,".- .. 1 *.A W .: ' -`~ ~. ,: . A; The original piping for both pools consisted of steel and/or cast iron pipe from the main drain to the surge pit and from the gutter to the surge pit. At this point it appears that fine adjustment of the system to satisfy the current State Health Code requirements regarding flow rates is near impossible. Current State Health Code does not allow separate bodies of water to share circulation equipment. Mechanical equipment room piping appears to be mostly all original cast iron with repairs and replacement parts of various grades of PVC pipe. Flow levels between these two pools are accomplished through a series of valve adjustments. Although this balance may be possible during static conditions, differing use patterns between the two pools present potential hazards that could be spreads due to poor flow rates and circulation patterns. This situation brings undue risk to users and works directly against efforts of water filtration and treatment. Both pools are fed through a series of wall return inlets. The entire pool return system is made of cast iron pipe which has been exposed to the destructive forces of chemically treated pool water since the initial fill of the pool. Cast iron pipes are an area of concern on any pool experiencing water loss problems. Current State Health Code requires that pools wider than 40' must have floor return inlets. This requirement makes renovating the existing competition pool expensive and risky since large portions of the pool floor will need to be removed and then replaced once underground ~;, ~~. ~p ~.~c.~~~. -s plumbing is installed.

DECKS The pool deck consists of swirl-finished cast concrete that completely encompasses both pools. The pool deck has been treated with Kool Deck which is aslurry-applied coating used to reduce pool deck temperature caused by sunshine. In this case the Kool Deck may have been used to mitigate the many problems with the pool deck, mainly cracking and rust stains from rusting reinforcing bar too close to the pool deck surface. The pool deck shows signs of heaving and de-lamination in several locations around the pools. The cracking and heaving in the pool deck has caused the formation of trip hazards which are a violation of the State Health Code. The width of the deck varies around the pools on all sides between 10 and 20 feet. The deck slopes away from the pools to channel drains that are located around the pool deck perimeter. Both pools are experiencing some puddling around drainage areas. Tile deck depth markers are inlaid in the deck's tiled and cantilevered portions. The the depth markers are comprised of mosaic tiles arranged to represent 6" high lettering. The children's pool has no depth markers on the pool deck, which violates current State Health Code. This presents a potential liability issue for both the City and the School District if someone were to have an accident in the children's pool. 4. MECHANICAL EQUIPMENT The two pools share every aspect of the water treatment system, which is a violation of the current State Health Code. The water treatment system is powered by one approximately 20 horsepower circulation pump. Due to the pump and pit configuration the pumps draw water from a single surge pit where the water make-up system is located. Page 5 Rowley l n$ e r n a t i o n a l Inc Seal Beach Feasibility Study September 2008 B. EXISTING FACILITY (continued) The filtration system totals 40.5 square feet of surface area. The maximum filter flow capacity is 729 gallons per minute (GPM). The pump provides approximately 688 GPM with a valve system that directs a portion of the treated water to the lap pool and the remaining to the children's pool. These numbers indicate that the pump is unable to provide the total required flow rate to satisfy both pools. Even if the State Health Code allowed pools to share equipment. The filter system is made of three manually operated high-rate sand filters. They appear to be sized appropriately to handle the pools' flow rates. The pump flow rate falls below current State Health Code requirements. The circulation system is equipped with a Blue-White Flow Sensor. This flow meter is a venture system and appears to be in good working order. The valves in the mechanical equipment room are made of cast iron and thermoplastic. All valves are manual and were found to be generally in fair working condition. Pool heating is accomplished via one Raypak Hy Delta commercial pool heater that appears to be in good condltion. This pool heating system looks to be the result of a recent pool equipment upgrade. This heater is the single source of heat for both pools. This pool heater is not the correct size to use on either pool after renovation. The pool water balance or chemical control is maintained via an Accu-trot Commercial Pool Water Controller. The Controller works by taking a filtered stream flow from the circulation loop and running it through a series of sensor wells to measure the waters pH level and the pool water's Oxidation Reduction Potential (ORP). ORP is a measure of the pool water's ability to instantly kill germs using adding chlorine products. The Controller starts and stops the flow of pH-control chemicals and chlorine products. This Controller appears to be in good condition. The Chlorine Feed System utilizes a Chloromatic Saltwater Chlorine Generation system to raise the ORP of the pool water. This feed system works by adding pure salt to the pool water. The salt water is then piped trough a chamber with titanium plates inside. An electrical charge is applied to the plates then the electrical field helps disassociate the chlorine from the sodium to form hypochlorous acid (chlorine and water) and also sodium hydroxide. The chlorine oxidizes the organic matter in the pool. The sodium hydroxide and the chlorine recombine in the pool to form salt (sodium chloride) and the process starts again. This equipment generally appears to be in good working order. Page 6 R o UV I e y International Inc Seal Beach Feasibility Study September 2008 8. EXISTING FACILITY (continued) The pH control is achieved by the use of a Liquid Metronix Acid Feed Pump. The acid feed pump is controlled by the Pool Water Controller and turns on and off based on the readings made by the Controller. The acid feed system appears to be in good working condition. 5. DECK EQUIPMENT The lap pool is equipped with five sets of pool ladders located at each corner. Anchorage for anon-user-operable Swim-Lift Handicap Lift was observed, though one was not seen in operation. Each of these systems appears to work functionally. This lift model is no longer on the state's approved list for easy access to swimmers with physical disabilities. Pool officials have stated that providing assistance to users of this lift creates problems for the lifeguards as well as opening the City to potential liability and litigation issues. The children's pool is similarly equipped for access. Competitive components of the lap pool include starting platforms located at one end of the pool, deck-mounted water polo goals, and floating racing lanes (a storage reel for the lane lines was not evident). All appear to be in fair operable condition. The competitive starting platform anchor sockets are located on the deck next to 3'6" depth of water. Rowley International Inc is of the opinion that the placement of starting platforms next to such shallow water presents a liability issue for both the City and the School District. Rowley International Inc recommends starting platforms be placed on the pool deck adjacent to no less than 7'0" of water. The competition pool is also fitted with a 1-meter diving board. The diving board and diving stand appear to be in reasonable condition. The mounting of the diving stand to the sloped deck has created a situation where the diving board has an uphill orientation as related to the water surface. The diving board is unsuitable for competition and can only be used for recreation. Additional deck equipment includes pool covers and pool cover reels. During the site visit there were no lifeguard chairs throughout the facility. All other pool deck equipment seems to be in reasonable condition and in operation at this time. 6. CHEMICAL ROOM The chlorine feeder is a saltwater generation unit which is placed in the corner of the mechanical equipment room in the corner where the circulation plumbing returns to the pools. This is the result of a recent mechanical system upgrade. Page 7 Rowley l n$ e r n a t i o n a l Inc Seal Beach Feasibility Study September 2008 B. EXISTING FACILITY (continued) The acid Is stored in a separate room to which Rowley International Inc did not have access on the day of the inspection. The acid is piped from the chemical room over to the circulation piping in the corner of the mechanical equipment room. The acid is introduced into the circulation piping via a LMI diaphragm pump which seemed to operation satisfactorily at the time of inspection. 7. RESTROOM FACILITIES During the site inspection Rowley International Inc discovered there was no access to restroom facilities from the swimming pool area. This is in direct violation of the State Health Code which dictates restroom requirements as a function of swimming pool surface area which is above and beyond the facility requirements outlined by the State Building Code. The lack of access to restroom facilities encourages bathers to stay in the pool rather than look for the restroom. This puts a significantly increased dirt load on the filtration and chemical sanitation equipment. This is of particular importance when many young children are present. This issue is made worse by the fact that the pool water and circulation equipment is shared by the two pools. There are restroom facilities on the opposite side of the gymnasium from the swim center. The County of Orange Environmental Health Department may require a new Restroom Facility with direct access to the pool facility. Rowley International has no way of knowing whether the County Health Department will require a new restroom facility however we feel that it is a very likely scenario even during a like kind renovation of the existing pool facility. The location of the existing restroom facility on the opposite side of the gymnasium from the pool area presents some unique issues which require consideration of both the City Staff and the School District. The current locations make it very difficult to control access from the school to the Pool area for school children. Conversely the current restroom location makes access of community bathers to the school very difficult to control. 8. CODE VIOLATIONS The following items have been identified as violations of various California State Health Codes that Rowley International Inc has encountered. It is important to mention violations of Codes where health and safety are concerned. a. The lap pool must be provided a separate pool water treatment system, and all plumbing connections between the pools must be eliminated. b. All parts of the pool shall be maintained in good repair. Floors shall be kept free of cracks and other defects. Page 8 R o w I e y I n t e r n a t i o n a I Inc Seal Beach Feasibility Study September 2008 B. EXISTING FACILITY (continued) c. The pool shall be equipped with a skimming method capable of continually withdrawing not less than 75% of the required circulation capacity, to provide continuous skimming of the water surface. d. Floor return inlets are required on pools exceeding 40' in width. e. Depth markers shall be located on the vertical portion of the wall so as to be clearly legible to bathers in the pool. f. Provisions for attaching a safety rope and buoys across the pool shall be installed where the water depth is 4'-6". I. Two recirculation inlets shall be required for the first 10,000 gallons of pool capacity and one additional inlet for each additional 10,000 gallons. Provisions shall be made for adjusting the volume and direction of flow from each return inlet. k. Handicap access is required at both pools. Historically, this requirement was met by providing ahand-operated portable pool lift device. Current requirements call for auser-operable device. I. The diving boards or platforms must be 5'-0" off the centerline of the main drain grates. m. Permanent depth markers with numerals a minimum of 3" high are required at the minimum depth, maximum depth, each end and around the perimeter at distances not to exceed 25'-0". Painted depth markers are not permitted. These depth markers are required on both the pool wall and the pool deck. n. The chemical feed equipment shall be electrically interlocked with the pool circulation pump to prevent chemical feeding when the circulation pump is turned off. o. The circulation system must provide a complete turnover of the pool water in 6 hours or less. p. An emergency phone number sign is required to be posted where visible from the deck. q. A "No Lifeguard on Duty Swim at Your Own Risk" sign must be posted. r. An occupancy load sign with clearly legible letters not less than 4" high shall be posted in a conspicuous place near the main entrance to a pool which shall indicate the number of occupants permitted for each pool. The Page 9 Ft o vv l e y l n t e r n a t i o n a l Inc Seal Beach Feasibility Study September 2008 B, EXISTING FACILITY (continued) California State Health Code has determined that the occupancy load shall be one person per 20 square feet of pool surface area. s. "No Diving" signs with minimum 4" high letters are required on pools with shallow water. t. An artificial respiration sign is required to be posted where visible from the deck. u. A floating ring buoy and safety rope is required. v. A body hook on a minimum-12'-long pole and a ring buoy with a 60' throw line are required. These items must be mounted where readily accessible for use. w. There are no restroom facilities for the pool users, which is a violation of the current State Health Code. Current restroom facility access is so limited that pool users would require access to the school restroom facilities; this may be a security issue when school is in session. The following item has been identified as a violation of the 2003 Uniform Building Code: a. Where drinking fountains are provided, at least one shall have a spout 33" from the floor with up-front, hand-operated controls for handicap access. Section 511©. 9. SPECIAL ISSUES The pool water loss reported by the pool operator is of special concern to the operation of this facility because of the financial loss: wasted water, wasted heating, and wasted chemical treatment. In addition, with the amount of water that has been measured, the undermining of the pool shell is a potential danger. Finding the source of the leak is a difficult task made more difficult by the fiberglass coating in the children's pool. As described earlier in this report, fiberglass is an inexpensive waterproof coating often used to repair worn or stained plaster. Unfortunately, when the fiberglass coating breaks down, it is be very difficult to find leaks due to the masking effects of the fiberglass. Page 10 R o w I e y I n t e r n a t i o n e I Inc Seal Beach Feasibility Study September 2008 C. RECOMMENDATIONS In reviewing the current condition of the facility both the pools could be brought into compliance with the State Health Code. Although there are many issues with both pools, it is not uncommon to see major renovations of these types of facilities when the facility requirements have changed very little from the time of the original construction. These major renovations are often successful in providing improved performance and appearance for a portion of the cost of a complete replacement. When an Owner's programming requirements change, no cost savings of renovating a facility can compensate for a facility that can't satisfy the programming needs of the community. Based upon Rowley International Ines discussions with the different user groups, Rowley International Inc feels that the programming of the facility has evolved to the point that, when coupled with the updates in the State Health Code, the best course of action would be to replace the existing pools with an aquatic facility capable of allowing a multitude of concurrent uses. To illustrate the differences the balance of this section will describe Rowley International Ines recommendations for a renovation followed by recommendations for a new pool with a few additional options. 1. POOL SHELL The concrete pool shells appear to be structurally sound. The lap pool shows many areas of surface rust where the reinforcing steel has been corroded by pool water. This indicates the plaster has failed and is in need of replacement. The preparation of the substrate is important as the new plaster relies on a strong mechanical bond between the roughened surface and new plaster. Other alternatives to plaster are available, such as fiberglass, but only plaster with proper chemical treatment will give 15-20 years of service. The gutter system on the lap pool is too small to serve any serious competitive need. The gutter system is of questionable size with regard to dealing with considerable surge capacity when several bathers are introduced to the pool at the same time. Since the lap pool utilizes agutter-and-surge-tank system and the children's pool utilizes a surface skimmer system, the connection of the same circulation piping and pump suction is suspect. The ability to control and adjust flow operation during dynamic and static con best. The expansion joints are always a source of concern. The lap pool has two expansion joints joining at a perpendicular intersection at the bottom of the pool. There are significant rust stains emanating from the expansion joints indicating both a water leak and compromised and rusting structural joint. Page 11 ditions of the two pools is difficult at ~; _ t ; ~~ ,+ .; ~.~. .. s ~-~a, d ~ 1 - ~..• .~ `•1 I ~i b ~ ~ $ e ~' ~ a ~ ~ ~ n ~ ~ ~ ~ C Seal Beach Feasibility Study September 2008 C, RECOMMENDATIONS (continued) The watertight integrity of all underwater light niches and conduit should be verified. Conformance to the National Electric Code should be confirmed. Underwater lights, niches, conduit, and junction boxes should be replaced to conform to Code. 2. PIPING We believe the best long-term solution is replacement of all ferrous piping. We recommend using Schedule 80 PVC pipe and fittings. All piping should be sized to limit water velocity in the pipes to 6 feet per second. This will ensure lower operating costs and higher pumping efficiency. Piping replacement would include all piping to properly separate the lap pool and children's pool and new pool floor inlets to better circulate the treated water back into the pool. All valves should also be replaced to provide an efficiently operating system. We recommend using Schedule 80 PVC fittings and valves with gear operators on valves over 6". 3. DECK The pool decks are generally in poor condition; however, with piping replacement comes trenching around the entire perimeter at each pool. When the decks are trenched approximately 35% of your deck will be removed to accommodate the piping replacement. At that time, the entire deck could be replaced or the remaining portions of deck could remain as a cost saving option; however, there are some deck slope issues making this option much less viable. Tile depth markers should also be added on the decks at the required spacing and vertically on the corresponding area of the deck to meet current State Health Code requirements. 4. MECHANICAL EQUIPMENT The existing equipment appears to be generally in poor condition. Separating the two pool mechanical systems obsoletes almost all of the equipment. New pumps should be provided with premium high-efficiency motors. The pumps should be installed in a pump pit to provide a flooded suction configuration that would allow each pool system to be shut down at night to provide additional operating cost savings. Page 12 Rowley I n t e r n a t i o n a l Inc Seal Beach Feasibility Study September 2008 C. RECOMMENDATIONS (continued) The existing high-rate sand filtration system is beyond its useful life and should be replaced. New fully automated high-rate sand filters should be installed. Automated filters eliminate the need for a manual operation to backwash the filters. The filter tanks are much smaller and have much less flow during a backwash cycle. As a result, high flow rates that typically cause problems to the sewer system are minimized and make-up cycles are reduced in volume. The existing gas-fired pool heater is in good shape. A heater of this size would not be correct for use on either pool once the circulation systems are separated. Consideration should be given to the use of direct-fired pool heaters. Pool heaters are much more efficient than domestic hot water systems. With consideration to today's current energy conditions, solar pool heat should be seriously considered for any new aquatic facility. New solar water heating technology has significantly reduced the cost of solar systems and improved the Return On Investment (ROI). The existing automated chemical control system borders on obsolescence and should be removed and replaced with a new system. Properly designed automatic chemical treatment systems continually monitor and feed chemicals as required to maintain the proper chemical balance in the pool water. This type of system uses less chemicals and requires less labor than manual treatment. By carefully controlling the pool water chemistry, damage to the mechanical equipment in the system and the pool finishes will be minimized. When installed, the new chemical control bypass lines (loop) should be routed to take in filtered pool water, pass through a Y-strainer, pass the sensor probes and flow indicator and return to each respective surge chamber. We recommend the installation of Siemens Strantrol System 31 with liquid chlorination systems using sodium hypochlorite, carbon dioxide for pH control, and Muriatic acid for alkalinity control. The chlorine and acid systems should all be housed in separate mechanical areas. These systems present a relatively safe pool chemical environment utilizing large storage tanks able to store a 2-to- 3-week supply of the chemicals. The chemicals can be purchased in bulk and delivered by a chemical company. Liquid chemicals are also available in Page 13 R ~ ~ ~ ~ ~ ~ ~ `~ ~ ~ a t ~ ~ n ~ I ' ~ C Seal Beach Feasibility Study September 2008 C. RECOMMENDATIONS (continued) 50-gallon drums. The downside of an all-liquid system is an increased potential for a chemical spill and additional hazardous chemical storage issues. Rowley International Inc recommends tertiary chemical containment in dedicated chemical rooms for each chemical. The electrical system for the mechanical equipment should be analyzed and modified to handle the loads of the equipment and to meet all current Codes. 5. DECK EQUIPMENT The diving equipment meets the current State Health Code; however, it does not satisfy competitive requirements. Rowley International Inc appreciates the City's need to provide diving programs; however, Rowley International Inc strongly recommends that any diving considerations for this existing lap pool be limited to 1-meter diving. The diving envelope of the exiting pool shell is not sufficient to accommodate 3-meter diving. Other deck equipment items including ladders, covers, and racing lanes are in working order and could remain. The portable handicap lift should be upgraded with auser-operated model to meet current State Health Code. MECHANICAL EQUIPMENT ROOM The chemical room is not sufficient to accommodate any chemicals and should be abandoned. The mechanical space is insufficient to house the systems described above. For this reason a new mechanical room or enclosure should be part of an existing facility renovation. The new swimming pool equipment room should not be attached to the existing gymnasium so that future renovation of the gymnasium would not require renovation of otherwise new swimming pool circulation systems. 7. SAFETY CONSIDERATIONS We recommend installing the warning signs in the deck around the shallow end of the both Pools (less than 4'-6" in depth) stating "Danger -Shallow Water - No Diving" with a universal "No Diving" graphic. All required safety signs should be provided and mounted on the walls around the pools to meet State Codes (See p. - v. on pages 9-10 of this report). 8. POOL REPLACEMENT As described in the second paragraph of this section (C. Recommendations) of the report, Rowley International Inc believes that the best solution is to replace the existing pool facility with an all new 50-meter x 25-yard multi-use pool or a Page 14 R o w I e y I n t e r n a t B o n a I Inc Seal Beach Feasibility Study September 2008 C. RECOMMENDATIONS (continued) combination of competitive and recreational pools. The renovation described above includes almost complete replacement of every aspect of the pool except for parts of the pool shell itself. The new pool would accommodate all aspects of the renovation plus the shell and deck. The new pool would be comprised of one-third deep water (12' to 13') to accommodate all aspects of a diving program, one-third intermediate depth (7') to accommodate competitive water polo, and one-third shallow water (3'-6" to 4'- 6") for instructional and recreational programs. The construction materials should be chosen with emphasis on long-term use and efficiency. An all-concrete shell featuring PVC piping with a floor return inlet system will provide many years of efficient service. The nature of the concrete shell is a sturdy base for many years. Concrete decking with inlaid ceramic the signage will meet the current codes and provide added safety as well as longevity. The mechanical systems should use the latest in automation. Fully automated permanent media filters and an automatic chemical feed system provide ease of maintenance and added life to the facility. The automated system will allow for overnight shutdowns that, when accompanied by the use of pool covers, will provide substantial savings in operation costs. D. OPTIONS Options for consideration in regards to the renovation of the facility include replacing the pools with a 50-meter pool or as described above refurbishing the existing pools. 1. 50-Meter Pool A 50-meter pool is 75' wide and 164' feet long. This size pool is very popular in large part due to its versatility. Covering over 12,000 square feet it provides considerable area for both shallow- and deep-water programming opportunities. The main advantages are the ability to program multiple training and instructional opportunities at the same time. Water polo and swim practice can be held at the same time. 2. Recreation Pool Municipal facilitates can benefit from some type of recreation pool with slightly warmer water and more play area and play features for children and the community at large. One advantage to having a separate recreation pool is that the recreation pool can be operated seasonally. By shutting down operation during the colder months, the city can make significant operational budget cuts. The competition pool can then be operated year-round for competition and training.

Refurbishment As described in detail above, both pools can be refurbished to provide efficient long lasting use. The key issue is whether or not the pools currently meet the needs of the community. 4. Community Recreation and Competitive Aquatics During our site visit, we interviewed several operational staff. The main purpose of the pools is Learn to Swim and Swim Team. These activities are quite important in a community such as Seal Beach with its proximity to the ocean. Learn to Swim programs become important at an earlier age than most communities. Aquatic programming in this and nearby communities is becoming more prevalent. Activities such as competitive swimming and water polo have become hugely popular sports for children. Community recreation should not be overlooked during the planning process. Shallow warm-water pools with children's play equipment and other multi-use areas have proven to be very successful in many municipal facilities. They allow for more community pride and involvement. Often the recreation pool becomes much more heavily used than the competition pool. Recreation pools with warmer water often draw segments of the community who normally are not inclined to use the competition pool. These groups include seniors for water aerobics and no-impact workouts; Mommy-and-Me classes for toddlers; handicap swimming; and exercise. E. PLANNING The planning process should include community or "Town Hall" meetings to determine the desires and concerns of the community regarding the proposed project through community input. It has been Rowley International !nc's experience that a small segment of the community will attend these meetings and become very passionate about their particular groups needs and wants. Rowley International Inc has seen many occasions where competitive swimming groups attend the meeting and attempt to drive the project to accommodate their purpose. What often happens is that a very large segment of the community (the silent majority) does not attend the meeting or provide input for the project but eventually will become the largest segment of the facility users. City officials must be aware of this during the planning process. This generally applies to recreational aspects of the proposed facilities. Recreational bodies of water often outdraw competitive bodies of water by an order of magnitude. This use often takes place during the hotter months. Recreational bodies of water may be operated seasonally allowing the City to save significantly on its operational budget. The recreational bodies of water often become such a big draw for the Page 16 Ft o w I e y I n t e r n a t i o n a I Inc Seal Beach Feasibility Study September 2008 F. PLANNING (continued) community that they become a significant source of income to offset some of the operating costs of the entire facility. Competition pools are more commonly operated year-round. Programming (training and competition) in this type of pool is very often scheduled years in advance. Club swimming and water polo often compete for the use of these facilities. Planning for a municipal aquatic facility must consider several factors, mainly: available facility infrastructure budget; both construction and design (soft) costs; operational costs for the proposed facility configuration. Staffing considerations must also be considered. Community use and availability may also impact parking and other environmental factors. Site Planning This particular site has many components that need to be considered in the planning and decision stage. The proximity to the school is an issue that needs attention and has been mentioned above. The existing tennis courts also provide an opportunity for additional programming or site layout changes. Entry and exit to the facility and its impact on local traffic must be considered in order to maximize utility of the site and the community. Availability of parking must always be taken into account for any facility. Site lighting and how it affects the surrounding community should also be examined. These are but a few considerations which need attention during the planning process. Page 17 I~ o !A/ l e y l n t e r n a$ i o n a l l n c Seal Beach Feasibility Study September 2008 F. PLANNING (continued) 2. Staffing During the planning process the City should also take into account the increased staffing requirements of a new facility. Lifeguards, maintenance and operations personnel, and administration are of considerable importance to a new municipal aquatic facility. Staffing issues should be addressed during design and construction so that operational budgets can be set for the impending opening of a new Aquatic Facility. These solutions need to be in place at the time of opening a new facility including an operational plan that can be reviewed by the County Health Agency. G.

H. DESIGN AND CONSTRUCTION SCHEDULE Rowley International Inc has estimated the Design and Construction Phases of this project based upon experience with swimming pool replacement projects. Rowley International Inc has no control over the time required by public agencies for document review and it is possible that more time than indicated below will be required. This project requires a specialty Contractor and it has been found with previous jobs that these contractors, if busy, may ask for more time, increase their profit margin, or not bid the project.

CONCLUSIONS Seal Beach Feasibility Study September 2008 Rowley International Inc has made recommendations with consideration given to the needs and concerns of the City. At the time of this report, it was Rowley International Ines understanding that the current pool configuration does not suitably provide for the programs desired. Despite the cost savings of a refurbishment, the City would be better suited for a complete pool replacement to satisfy their growing needs. Construction of a new Pool Facility gives the City of Seal Beach the opportunity to maximize the use of the existing site. Rowley International Inc recommends that all the items identified as Code violations be corrected at some time in the future; it should be kept in.mind that these laws are for the safety and health of the users. Rowley International Ines estimates of construction costs and schedules are based upon many actual projects of a similar nature in the area which Rowley International Inc has completed over the past few years. Detailed drawings including pool plans, deck areas, and fences are beyond the scope of this report; however, they will certainly be included in the construction documents for the work described in this report.
