Silver Oaks Estates Project

The Silver Oaks Estates Project in Clayton, California, involves the demolition of existing residential structures and outbuildings on an 8.03-acre portion of a 13.96-acre site, followed by the construction of 32 new single-family homes, three of which will include junior accessory dwelling units. The project also encompasses new roadway systems, utility upgrades, and stormwater infrastructure designed to protect federally and state-listed species such as the California red-legged frog, foothill yellow-legged frog, and California tiger salamander. Critical to the project’s approval is compliance with the Contra Costa County Habitat Conservation Plan/Natural Community Conservation Plan, the California Endangered Species Act, and the Lake and Streambed Alteration Agreement. Infrastructure features, including storm drain grates with openings no wider than 16 mm, slanted curbs with a maximum 45-degree angle, escape ramps in basins made of perforated metal with synthetic matting, exclusion fencing, and one-way outfall gates, must be submitted to the California Department of Fish and Wildlife at least 90 days prior to construction, with approval required before implementation. Acceptance of these designs is granted administratively by CDFW, and if no response is received within 30 days, the designs are considered approved. The project site, located near Oakhurst Drive at Yolanda Circle with APN 118-020-029, is under the jurisdiction of the City of Clayton as the lead agency, with no federal procurement clauses, contract types, pricing data, or federal acquisition regulations applicable. Environmental compliance and mitigation measures, rather than standard contracting terms, govern project execution, with no identified contract value, payment office, invoicing system, or designated contracting officer. All activities are tied to CEQA environmental review processes, with project updates and notices disseminated through the City of Clayton’s website and state clearinghouse submissions.
