SENT BY: HP LASERJET 3150; 6502619102; MAR-21-02 g:36AM; PAGE 7/10 · Perform pipeline alignment reconnaissance, · Investigate opportunities and constraints for siting a storagn/pumping facility in thc Greater BayfTont Area or within the Central Redwood City area · Refine the pipeline alignments and create a (}tS map depicting proposed transmission and distribution pipeline alignments. · Perform a hydraulic analysis of the entire transmission and distribution system, and size the proposed transmission and distribution pipelines and pumping facilities using previously established criteria and methodology. Alternative t will consider that all pumping and storage facilities will be constructed at SBSA's site. Alternatives 2, 3 and 4 will investigate the potential benefits of providing an additional storage/pumping facility on a site(s) in the Greater Bayfi'ont Area, Central Redwood City, or both. Following the hydraulic analysis work, an overall system map will be prepared in GIS or on aerial photography, showing transmission and distribution pipelines, pipeline lengths and diameters, and major pipeline crossings of streams, bridges, railways, highways, and San Francisco's Hetch-hetchy pipelines for both alternatives. A conceptual site plan will be prepared showing the location of pumping and storage facilities at SBSA's site, and at site(s) in the other areas designated by the City on existing aerial photography. A matrix of pipeline lengths and major crossings will be provided to compare the alternatives. Subtask 3.4 - Prepare Estimates of Probable Capital and Operating Costs A planning level estimate of probable capital, and operations and maintcnanco costs will be prepared for required treatment and distribution facilities, under each distribution system alternative using previously established cost criteria and methodology. The City will provide cost guidance on any land acquisitions or right-of-way needs identified. Subtask 3.5 - Other Monetary and Non-Monetary Considerations An assessment of potential internal and external benefits that are a direct result of tho project will be performed, Internal benetits are those associated with the producer, supplier or customer of the recycled water project, and can include items such as avoided costs for creating a new water supply or for water supply reliability, External benefits are those enjoyed by society, other utilities and their customers, and can include environmental or economic improvements, such as the creation of a wetland sanctuary or the freeing up of water supply that might allow a manufacturer to build a new facility creating jobs and tax revenues. A meeting will be conducted with the City and ~el~cted attendees to discuss potential internal and external benefits. These benefits will be used to perform an economic analysis under the following subtask. The City will provide guidance on potable water supply cost and benefit related items.
