Auburn FAQ
Do I need a TESC plan for a small landscaping project?
Most small residential landscape projects fall below thresholds, but any work on Lea Hill or West Hill steep slopes, near streams, or over 7,000 square feet generally requires a TESC plan.
Can I continue excavation in November?
Wet-season rules reduce the allowable exposed area and add stabilization deadlines. Projects must plan for rapid covers, mats, or seeding between grading phases.
