7.1.A. - Page 17 recycled water system. Redwood City entered into an interagency agreement with SBSA to ensure the success recycled water program. Description of Project The Redwood City Recycled Water Project was implemented in multiple phases over several years, beginning with recycled water delivery to the Redwood Shores area for the 2004 irrigation season and to the Greater Bayfront area for the 2010 irrigation season. Expansion to portions of the Central Redwood City area is planned for the 2016 irrigation season. Figure 3 shows the anticipated distribution system for the Greater Bayfront area, and Figure 4 shows the anticipated system for the Central Redwood City area. Development in the Central Redwood City area is currently planned for properties outside of existing Recycled Water Service Area. For this reason The City plans to expand the Recycled Water Service Area to encompass the areas outside the existing Recycled Water Service Area contiguous with its Potable Water Service Area east of Alameda del Las Pulgas, and west of Alameda de Las Pulgas north of Edgewood Rd. The Expanded Recycled water Service Area is shown in Figure 5. The expanded service area will also include off-site recycled water storage reservoirs and pump stations. It is anticipated that the Greater Bayfront and Central Redwood City areas will each require a storage facility and pump station for the efficient operation of the system. Although the specific location and design of these facilities has not yet been determined, the preliminary hydraulic modeling for the system indicates approximate locations for these facilities within each service area, and they are shown in Figures 3 and 4. The reservoir/pump station in the Greater Bayfront area is shown near the City's Police Department facility on Maple Street, and the reservoir/ pump station in the Central Redwood City area is shown within Red Morton Community Park. The uses of recycled water in the expanded service areas also will be primarily landscape irrigation, but may include dust control, toilet flushing, firefighting, and industrial process uses, such as sand washing, concrete batch plants, and other industrial customers primarily in the Port of Redwood City area. To allow use of recycled water for construction operations and dust control, recycled water fill stations for water trucks will be installed in at least three locations, one at the SBSA treatment plant and others in conjunction with the off-site storage reservoir and pump station facilities. Fill station facilities typically consist of a hydrant with an access drive area surrounding it. Construction Methods and Schedule Construction of pipelines would occur primarily within existing roadway and public easement rights-of-way. Most pipeline construction would be performed by the "trench-and-cover" method, which involves excavating an open trench, laying pipe, and replacing and compacting soil to refill the trench. For construction in paved areas, the trench area is then repaved. For 3
