Tuolumne County regulates development along waterways and lake shorelines to protect water quality and natural habitats. The county's General Plan and zoning ordinances establish setback requirements and development restrictions near rivers, streams, and reservoirs including Don Pedro Reservoir, New Melones Lake, and the Tuolumne and Stanislaus Rivers. Projects within riparian buffer zones require additional review.
Tuolumne County's General Plan Natural Resources chapter and zoning ordinances establish protections for shoreline and riparian areas. Development near waterways is subject to setback requirements that vary by the type of water body. The county requires environmental review for projects within riparian buffer zones, typically 50 to 100 feet from the ordinary high-water mark of perennial streams and lakes. New structures and grading activities near Don Pedro Reservoir, New Melones Lake, and major rivers require compliance with both county regulations and applicable state and federal requirements. The county works with agencies including the U.S. Army Corps of Engineers, California Department of Fish and Wildlife, and the Regional Water Quality Control Board on shoreline development review. Erosion control measures are required for any construction activity near waterways.
Violations of shoreline management regulations may result in stop-work orders, required restoration of disturbed areas, and administrative penalties. Projects that proceed without required environmental review may face enforcement action from both the county and state regulatory agencies.
