ENG AUTHORIZATION TO APPROPRIATE FUNDS FOR MAERKLE FACILITY IMPROVEMENTS DEPT. HEAD CITY ATTY. CITY MGR. \jy* ^ RECOMMENDED ACTION: Adopt Resolution No. Improvements. ITEM EXPLANATION: 1309 authorizing the appropriation of funds for the Maerkle Facility Maerkle Dam reservoir and its auxiliary facilities are located in the northeast part of the City and are a critical part of the potable water supply system for the City. Maerkle Dam reservoir (formerly known as Squires Dam reservoir) was initially constructed in 1963. In the late 1980's and early 1990's, various auxiliary facilities were added, including a 10 million gallon concrete storage tank, transmission pipelines, a 33.5 mgd (million gallons per day) pump station, and chlorination facilities. In May 2007, staff commissioned a study to evaluate all the facilities at Maerkle Dam reservoir. The study report identified about 20 items at the site that need replacement to meet current code requirements for health and safety and to maintain reliability of this supply source. The items are summarized in Exhibit 2. Staff further evaluated the report to prioritize the improvements into first and second year implementation. On September 18, 2007, Council awarded a contract for the floating cover rainwater system replacement and cover cleaning. The rainwater system replacement and cover cleaning were initiated before the above-mentioned study as an immediate response to a California Department of Health inspection and the rainwater system condition. Therefore, this Maerkle Facility Improvements project does not include these two items. ENVIRONMENTAL IMPACT: This project is a Class 2 categorical exemption (replacement or reconstruction of existing structures or facilities) and is, therefore, exempt from environmental review pursuant to Section 15302 of the California Environmental Quality Act (CEQA). FISCAL IMPACT: In order to implement the recommended improvements, the replacement facilities need to be designed and bid documents prepared. The Table below summarizes the anticipated costs for the project.

This project is not in the current Fiscal Year 2007-2008 CIP. At the time of budget preparation for the 2007-2008 CIP the study to evaluate the needs at this facility was underway and sufficient information was not available to determine fiscal impacts. Staff is requesting that an appropriation from the Water Replacement Fund be approved at this time to finance the project. Sufficient funds are available in the Water Replacement Fund to accommodate the cost of this project. OPTIONS Staff has identified three possible options for the project: 1. Implement the project as defined by approving this agenda bill and directing staff to implement all improvements identified for the project. 2. Phase the project by authorizing replacement of the most critical components which include the variable frequency drives, chlorine gas scrubbers, lower access gate, and ammonia room chiller for a cost of about $1.18 million, and postpone the remaining project components to a future fiscal year. 3. Postpone the project to a future fiscal year. This will delay the improvements, impact the reliability of this water supply, and cause the facility to be out of compliance with safety codes and security requirements. EXHIBITS: 1. 2. 3.
