Tuolumne County requires grading permits for significant earthwork. The Engineering Division reviews all grading plans for drainage, erosion control, and slope stability in the Sierra foothill terrain.
Tuolumne County's Engineering and Development Division administers grading permits under the county ordinance code. Grading permits are required for earthwork exceeding thresholds set by the county (typically 50+ cubic yards of cut or fill, or work on slopes exceeding specified grades). Plans must address drainage patterns, slope stability, erosion control, and downstream impacts. The county's granitic soils and steep terrain require careful grading design. All grading must maintain natural drainage patterns or provide engineered alternatives. Projects must comply with county road standards if affecting county road drainage. The Engineering Division can be reached at 209-533-5633 for grading permit inquiries.
Grading without permit: stop work order, retroactive permit with penalty fees. Drainage obstruction: Engineering enforcement.
