Bellevue FAQ
Kirkland FAQ
Do I need a TESC plan for a small landscaping project?
Most small residential landscape projects fall below thresholds, but any work on 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.
