Document Description
San Mateo County proposes to construct a new 13,000-square foot one-story radio service facility at 752 Chestnut Street. The County is the lead agency and sponsor under the California Environmental Quality Act (CEQA). The project site, which is owned by San Mateo County, is located on one parcel with an address of 752 Chestnut Street (APN 054-063-180). 752 Chestnut Street is in the eastern portion of Redwood City, San Mateo County, California. The 3.4-acre parcel containing the project site is predominantly flat. The site is accessible via driveways on Chestnut Street and Spring Street. The eastern and southern property lines are adjacent to surrounding development. The project site is in an established neighborhood that contains a mix of existing land uses. The project site is bordered by a one-story retail building to the east and a single-family residential neighborhood to the south. Across Spring Street from the project site are parking areas and an office building, and across from Chestnut Street is a single-family residential neighborhood. State Route (SR) 84 is located southeast of the project site, separated by a mix of commercial, single-family residential, and multifamily residential development. The project would replace the existing 2,700 square-foot one-story building used for County pest control services along the western property line with a new 13,000 square-foot two-story radio service facility. The new building would contain both office space and a service garage to work on County vehicles and radio equipment. Condensers and a heat recovering unit would be located on the east side of the new building. An emergency generator would be located east of the new building near the southern property line. Operation of the project would be similar to that of the prior radio service facility and would include monitoring of communication on all County two-way radios, equipment storage, and repair of County radio equipment on an as-needed basis. All other existing uses currently conducted at the Grant Corporation Yard including office, outdoor and indoor storage and vehicle and equipment storage, maintenance, and repair, would continue to operate at existing capacities under the proposed project. No new curb cuts are proposed. Grading required for the project would be designed to conform to the existing site as closely as possible and excavation would be minimal; no basement level or pile driving are proposed as part of the project. The amount of grading planned is the minimum required to allow for the construction of a level building pad, in conformance with current Building Codes. The maximum depth of excavation activities would be approximately 8 to 10 feet, where the depth to groundwater is approximately 13 to 15 feet below ground surface (bgs). The entire volume of material to be excavated would primarily be exported offsite. No significant import or export of soil or engineered fill material is anticipated. No trees would be removed. Some weedy ground cover would be removed to accommodate construction of the new radio service building. New drainage infrastructure is proposed with the intention of maintaining the existing flows and direction of stormwater runoff. The project would include new landscaping with recycled wood chips in all newly landscaped areas.
