Specifications include, but are not limited to: The Marin County Flood Control and Water Conservation District (District) completed construction of the Sunnyside Flood Detention and Storage (FDS) Basin in Fairfax, California in Spring of 2023. This project is part of the larger San Anselmo Flood Risk Reduction (SAFRR) Project. The SAFRR Project includes: the FDS Basin, Building Bridge #2 (BB2) removal, and BB2 downstream mitigation. The purpose of the offline Sunnyside FDS Basin is to divert and store excess high flow runoff from Fairfax Creek, which reduces peak flow and flooding downstream. Vegetation was planted at the FDS site as part CEQA (California Environmental Quality Act) and permit mitigation requirements; however, some has subsequently died. Not all of the mitigation and CEQA planting has been installed. The District seeks proposals from interested contractors for trade/general services to install, maintain, monitor, and adaptively manage several components of vegetation associated with the FDS Basin and its off-site mitigation site permit and CEQA requirements. The off-site mitigation area is within San Geronimo Commons in Woodacre, approximately three miles west of the FDS site. A vicinity and location map for both sites are shown in Attachment 1. The District is requesting proposals to: install plants, irrigation, and a water tank at the off-site mitigation area; install replacement plants at the FDS site; monitor both sites to fulfill permit requirements; and adaptively manage of both sites to comply with permit requirements and provide fire fuel reduction. Work will begin this winter and continue for 5 years (per the permit requirements). Planting is expected to begin within one week of the contract being awarded.
