Modification and variance for an existing T-Mobile Telecommunications Facility, County File #CDLP23-02030

Contra Costa County is reviewing a land use permit modification for an existing T-Mobile telecommunications facility located at 4723 Suzanne Drive in Pittsburg, California, to expand the lease area by approximately 74 square feet and grant a variance to reduce the required side yard setback from 50 feet to approximately 9 feet, as permitted under County Code Section 88-24.406(d) for wireless facilities. The proposed modifications include the installation of a new 25kVA transformer on a dedicated concrete pad, 8 permanent and 2 removable bollards up to 4 feet in height, 34 feet of new underground conduit within a newly established 3-foot utility easement, and 430 feet of additional underground conduit within an existing 10-foot easement connecting to the transformer. The project also entails relocating an existing 100-amp meter/main and panel pedestal, installing a new 200-amp meter/main disconnect and a new 200-amp power protection cabinet, running feed conductors from the new meter to the PPC through pre-existing conduit, installing a new H-frame, and reconnecting all existing electrical loads from the removed AC panel to the new PPC. The work is to be performed by Centerline Communications at the current facility site in the unincorporated area of Pittsburg, with all construction activities confined to the existing tower footprint and adjacent approved easement zones. The application has been submitted under County File #CDLP23-02030 and is supported by a certified exemption finding under the California Environmental Quality Act (CEQA) Guidelines Sections 15301(b) and 15303(d), which categorize the modification as an existing facility upgrade involving minor improvements and small structures that do not constitute significant environmental impacts. A Notice of Exemption has been filed with the County, fulfilling the necessary environmental compliance requirements. There is no federal procurement component to this action, and no Federal Acquisition Regulation (FAR) clauses, contract values, payment terms, or federal contract administration data are involved. The project does not require competitive bidding or evaluation factors as it is a ministerial permitting process governed solely by local land use and zoning codes. The applicant, Centerline Communications, submitted the request through the County’s Department of Conservation and Development, with Syd Sotoodeh, Senior Planner, designated as the primary point of contact. The submission deadline was January 22, 202
