Single-family additions disturbing under one acre typically do not trigger the SESC permit, but slope and proximity to waterways may still require erosion controls during construction.
Can I wash my car in the driveway?
Occasional residential car washing is allowed, but commercial washing or dumping wash water into a storm drain is an illicit discharge subject to fines.
