UPE24-0094, Cleanup and Restoration Project

The Cleanup and Restoration Project, identified as UPE24-0094, is a forecast initiative by the County of Sonoma to remedy grading and zoning violations VPL23-0364 and VGR23-0025 on a 116-acre parcel located at 2975 Calistoga Road in Santa Rosa, California. The primary scope of work involves the removal of approximately 23,000 cubic yards of unpermitted fill, including imported soil, woody debris, and a culvert, from tributary drainages, wetlands, and riparian areas. The project aims to restore the site topography to pre-violation conditions, specifically focusing on the 200-foot Riparian Corridor setback along Mark West Creek. Key deliverables include the revegetation and enhancement of upland, riparian, and wetland areas, the creation of additional seasonal wetlands, and streambank stabilization for an area not exceeding five acres. The project is categorized as a small habitat restoration project and is exempt from CEQA under California Administrative Code Section 15333, while also adhering to Sonoma County Code Section 23A. Administrative approval for the project was granted on August 27, 2026, with the official notice posted on September 1, 2026.
