EXHIBIT "A" SCOPE OF SERVICES. TIME AND FEE SCHEDULES Environmental consulting services for the preparation of an Initial Study and Mitigated Negative Declaration (IS/MND)for the new water tank, pump station and pipelines proposed for the California Pressure Zone in the Emerald Hills area PROJECT DESCRIPTION: The City of Redwood City (the City) proposes to construct a new 0.8 to 1 million gallon water tank with associated water pipeline and pump station facilities. The new water tank is being proposed in the California Pressure Zone of the Emerald Hills area of the City primarily to provide additional water storage capacity to meet fire flow requirements. The new water tank and pump station would also provide additional storage capacity for normal operations and emergency situations. As currently proposed by the City, the project consists of: • The construction of the new 0.8 to 1 million gallon water tank on a City owned site at the corner of California Way and Tum Suden Way; • Replacement or repair of existing pipeline that will connect the new water tank to the Easter Bowl and Easter Cross water tanks, both located up-slope of the project site; • Construction of a new pipeline between the new water tank and the new pump station on the project site; • Construction of a new 2,000 foot length of water pipeline from the new tank to an existing pipeline at Jefferson Avenue and Fallen Leaf Way; and • The replacement of an existing pump station on site. Based on the preliminary tank design, the water tank would be approximately 74-82 feet in diameter and 28 feet high. The City is proposing to construct the new tank in the same or near the location where two water tanks used to be located but were removed in 1999. The new tank would be painted a natural color to blend with the surrounding vegetation and reduce visibility. A 6-foot security fence with razor wire would be constructed around the tank. A pipeline connecting the new tank to the existing up-slope Easter Bowl (1.2 million gallon) and Easter Cross (0.1 million gallon) water tanks would be repaired or replaced entirely. This pipeline travels uphill through the undeveloped portions of the project parcel and under the road bed of California Way. The existing pump station on site would be removed and a new pump station would be constructed near the new water tank. The project also includes the construction of an approximately 2,000 foot long water pipeline connecting the new water tank to an existing water line at the intersection of Jefferson Avenue and Fallen Leaf Way. The new pipeline would likely be 8 inches in diameter and would be placed in the roadbed of California Way and Jefferson Avenue. The project site is located at the intersection of California Way and Tum Suden Way in the Emerald Hills area of Redwood City and is surrounded on all sides by single-family hillside residential development. The project site is at the border of Redwood City and San Mateo County. Edgewood County Park is located a short distance west of the site, and the Emerald Hills Golf Course is to the east. The entire parcel size is 377,862 square feet (8.7 acres); but the tank, pipeline and pump station area is a small portion of the entire site. The Assessor's Parcel Number(APN) is 068-271-010.
