THE CITY Of CITY COUNCIL AGENDA REPORT 8 PLEASANTON. February 21, 2017 Engineering TITLE: PRESENTATION OF A REPORT DETAILING INFRASTRUCTURE IMPROVEMENTS NECESSARY AND COST TO EXTEND WATER AND SEWER UTILITIES INTO THE UNINCORPORATED HAPPY VALLEY AREA SUMMARY: On February 16, 2016, City Council approved a contract with RMC Water and Environment (RMC) to perform a study to determine public infrastructure improvements necessary, and cost to extend City water and sewer utilities into the unincorporated Happy Valley Area. The study evaluated improvements necessary to serve every property within Happy Valley as they currently exist, as well as when properties are subdivided to build -out as envisioned in the 2002 Happy Valley Specific Plan. The report is now complete and a copy is attached. The report shows how nearby City public water utilities can be extended to serve every property within the Happy Valley Area and provide adequate fire flow at hydrants placed along the extended pipeline alignment. Similarly, the report shows how sewer pipelines can be extended to serve every property in the Happy Valley Area. The Pleasanton Municipal Code requires that every property connected to water and /or sewer have a direct connection to a public water or sewer main. The pipeline extensions as proposed conform to this municipal code requirement. The report also includes cost estimates to design and construct each utility extension. The total cost to design and construct the public water utility extension is estimated at $2.28 million. The total cost to design and construct the necessary public sewer utility is estimated to be $3.42 million. The cost estimate assumes the County - owned Happy Valley Road and the "common" private property access drives, such as Laura Lane, Mockingbird Lane, and Bird Lane will be made available to the City for the public utility installation at no cost. The cost estimate also assumes the existing roadway surfaces will only be restored to their current condition, which in some cases is relatively unimproved gravel. The costs as stated above are only for the extension of the water and sewer utilities. They do not include the pro -rata share of water and sewer installed in Sycamore and Alisal Roads to serve the golf course and golf course housing development (the backbone of the utilities that are extended to each property in unincorporated Happy Valley); the connection fees required by Zone 7, DSRSD, and the City; and the cost of the Alameda Local Agency Formation Commission (LAFCo) consideration of Out of Service Area (OSA) Agreements required to serve each property outside the City service area. These additional and significant costs of connection to City water and sewer systems are detailed in the "Discussion" section of this report to provide a complete understanding of the cost for a property in the unincorporated Happy Valley area to connect to City water and sewer utilities.
