Erosion Control: Vacaville vs Vallejo

Do I need a grading permit in unincorporated Solano County?

Almost always, unless your project is small-fill and meets every Chapter 31 exemption condition — under 50 cubic yards, under 5,000 sq ft of surface area, under 3 feet deep, on slopes flatter than 7:1, no change to off-site drainage, no structural use, and prompt revegetation. Anything bigger or steeper requires a grading permit from Resource Management — Public Works.

What erosion controls does Solano County require?

Chapter 31 grading permits typically require an approved erosion-control plan with BMPs such as fiber rolls, silt fences, sediment basins, stabilized construction entrances, and hydroseeding or revegetation. The County imposes heightened controls during the October 15 – April 15 wet season, and projects of 1 acre or more must also follow the State Construction General Permit and its SWPPP requirements.

What if I grade my property without a permit?

Solano County Public Works can issue a stop-work order, require you to apply for an after-the-fact permit (usually at higher fees), and order remedial work to restore stable drainage. If sediment reaches a creek or the Suisun Marsh, the Regional Water Quality Control Board can impose Clean Water Act civil penalties up to $10,000 per day per violation.

Do I need erosion control for a small project?

Most jurisdictions require erosion control for any ground disturbance over 500 to 1,000 square feet. Check Vallejo grading permit requirements.

Who inspects erosion controls?

Vallejo building or public works department inspects during active construction. Federal EPA NPDES permits may also apply for sites over one acre.
