Ingram, City Manager FROM: Sean Crumby P.E., Director of Public Works SUBJECT: RECEIVE AND FILE UPDATE TO CITYWIDE STORM DRAIN PROGRAM SUMMARY OF REQUEST: Receive and file update to the Citywide Storm Drain Program. BACKGROUND AND ANALYSIS: In December 2008 the City Council allocated $5 million in General Funds to construct Storm Drain improvements throughout the City. The projects were prioritized in accordance with the 2008 Master Plan of Drainage. This report will summarize the expenditures of activities related to this allocation. A summary of the projects and expenditures is as follows: Date of Notice of General Fund Project Completion Final Project Cost portion Candleberry Ave Storm Drain Project December 14, 2009 $1,741,969.80 $1,131,472.80 SD 0901 Electric Avenue Storm July 11, 2011 $1,925,000.00* $1,908,000.00 Drain Improvements Total $3,666,969.80 $3,039,472.80 * Final invoices for Electric Avenue have not been received at this time. Staff anticipates the number presented to be an estimation of the final cost. These are some of the largest storm drain construction projects that have been undertaken by the City and are a significant accomplishment. Even though only $1.96 million remains from the original $5.0 million allocation, the current FY 2011/12 Budget and Capital Improvement document have $2,000,000 budgeted for storm drain improvements. These improvements consist of two projects. The two projects are described as follows: Agenda Item 0 Page 2 Navy Drainage Easements SD1202 The FY 2011 -12 Budget and Capital Improvement documents have allocated $200,000 for construction of the improvements within Navy Drainage Easements. The City has several drainage easements that pass storm drain flow from portions of the Hill and Old Town across the Navy and outlet into Anaheim Bay. This drainage has been allowed via drainage easements that were executed in November 1950. The easement has expired and the Navy requested maintenance be performed within the drainage channels that convey the flow to the Anaheim Bay, prior to extension of a new easement document. The City did not have funding budgeted for this activity and the Navy graciously extended the easement for one year to allow for funding and environmental documents to be processed for the maintenance activity. It is anticipated that this project will move forward in FY 2011 -12. Citywide Storm Drain Improvements SD1201 The FY 2011 -12 Budget and Capital Improvement documents have allocated $1,800,000 for construction of the next priority Storm Drain project within the City. There are two priority projects to be considered for immediate delivery with the available funding. Those projects are: Storm Drain WE -1 Electric Avenue (Corsair Way to Marina Drive) Storm Drain Improvements have been constructed to this drainage system within Corsair Way (completed in 2006), and at the West End Pump Station (completed in 2008). This portion of the existing drainage system does not carry a 10 -year storm event. This project extends the increased flood protection up to Marina Drive. The estimated cost within the 2008 Storm Drain Master Plan is $2.62 million. The two previous storm drain projects were completed at 20% below the cost estimated within the Storm Drain Master Plan. Applying a similar factor will bring this anticipated project cost down to $2.10 million. Additionally, a portion of the construction will involve relocation of water and sewer facilities to accommodate the storm drain system. Relocation of those facilities can be funded by the water and sewer enterprise accounts. If the project cost exceeds funding limits, this project can be augmented with funding from the Redevelopment Agency as this project is located within and directly benefits the Redevelopment Project Area. Storm Drain CPE6 Ironwood Avenue at Guava Ave and Elder Ave Storm Drain Improvements have been constructed on Lampson Avenue (completed in 2005 and 2009). At both intersections of Ironwood Avenue with Guava Avenue, and Ironwood Avenue with Elder Avenue, undersized storm drain lines cross between private residential properties and drain across Lampson Avenue to the Old Ranch Golf Course. The easements allowing those storm drain lines are narrow (between properties). Upsizing of these lines will be extremely difficult due to the proximity of housing foundations and have a severe construction impact to those residents. Due to these challenges, the Master Plan of Drainage has identified two projects to move this drainage flow out of the area Page 3 for a total approximate cost of $8.2 million. Staff has been reviewing the situation and has come up with the below potential solution to solve the drainage problem at a significantly reduced cost. There are 10 properties that lie on the northern side of Ironwood Avenue between Guava Avenue and Elder Avenue. Should one of those homes be acquired by the City, an upsized storm drain can be constructed for a significantly lower cost than the $8.2 million identified within the Master Plan of Drainage. It is likely that this project can be constructed at a cost of under $1.0 million. This property can also become a small pocket park for the community after the construction is complete as the entire storm drain will reside underground. It is estimated that those homes are currently valued at between $600,000 and $700,000. ENVIRONMENTAL IMPACT: None with this action. This project will comply with all requirements of the California Environmental Quality Act. Detailed information will be determined and presented at the appropriate time as the project goes through design. FINANCIAL IMPACT: No action at this time. RECOMMENDATION: It is recommended that Citywide Storm Drain Improvements proceed as follows: • Set aside $700,000 towards purchase of a property on Ironwood Avenue for the purpose of constructing future storm drain improvements. These funds will be allocated from the $1.8 million that has been budgeted for project SD1201. When the next property is listed for sale, the City can enter into negotiations and purchase the property for the appraised value at that time. • Begin design and construction on Storm Drain WE -1 within Electric Avenue. Detailed cost estimates and funding alternatives will be brought to the City Council at the time that plans and specifications are being approved (prior to bidding).
