Cole Grade Road Improvement Project

The Cole Grade Road Improvement Project, led by the San Diego County Department of Public Works and regulated under the California Department of Fish and Wildlife’s Streambed Alteration Agreement EPIMS-SDO-34795-R5, involves roadway widening and ecological mitigation work along two unnamed tributaries to Keys Creek in San Diego County. The project includes constructing a 12-foot-wide decomposed granite pathway for pedestrians and equestrians on the west side of the road, installing drainage swales on both sides, replacing a double-box culvert at Tributary A with a bridge complete with headwalls and abutments, and performing an in-kind replacement of a single-box culvert at Tributary B. All construction activities are to be conducted in two phases to maintain traffic flow, with temporary water flow diversion and vegetation removal for equipment access required to minimize environmental disruption. The project is expected to last up to 18 months and is subject to strict compliance with Fish and Game Code Section 1602 and the California Environmental Quality Act, including adherence to an adopted Mitigation Reporting and Monitoring Plan. The California Department of Fish and Wildlife holds authority over inspection and acceptance, ensuring environmental standards are met, while San Diego County serves as the lead applicant and contractor. No formal contract value, pricing details, or federal acquisition regulation clauses are included in the documentation, as this is a state-regulated environmental and infrastructure project rather than a federally procured contract. There are no identified solicitation numbers, contract types, evaluation factors, or socioeconomic certifications provided, and no financial line items or payment instructions exist in the materials. Key contact points are Jennifer Blackhall of CDFW and Thomas Duffy of San Diego County, who serve as the primary environmental and planning liaisons, respectively. The project’s place of performance is precisely located at Assessor’s Parcel Number 001-332-01-18 in San Diego County, with coordinates provided for geographic reference. All activities are designed to balance infrastructure improvement with ecological protection, relying on state regulatory frameworks rather than federal procurement structures for authorization and oversight.
