Environmental Rules in Clovis, CA: What Residents Actually Need to Know

If you live in Clovis or are thinking about moving there, environmental rules are one of those things you probably won't think about until they affect you directly. Clovis has 5 specific rules on the books covering different aspects of environmental rules, and some of them might surprise you.

Stormwater Management

Clovis is a Phase II MS4 permittee under the State Water Board NPDES program. Only rainwater allowed in storm drains—no washwater, pool water, paint, or chemicals. New/redevelopment projects must manage post-construction runoff per the city's Stormwater Management Plan.

Illicit discharge: $500–$10,000/day per state Porter-Cologne Act plus local fines. Car washing on driveway is allowed; commercial washing must drain to sewer.

Key details: Permit Trigger: >50 cy or >3 ft cut/fill. Standard: CBC Appendix J. Engineer: Required for major grading. Drainage: No impact on neighbors. Department: Planning & Development.

Unpermitted grading: stop-work order, after-the-fact permit fees (often 2x standard), and restoration if drainage is altered.

Erosion Control

Grading/construction sites require erosion and sediment controls per Clovis Municipal Code Title 9 and the city's SWPPP requirements. BMPs required year-round, with enhanced controls during the wet season (Oct 1–Apr 30).

Key details: State Permit: CGP if 1+ acre disturbed. SWPPP: Required for 1+ acre. Wet Season: Oct 1 – Apr 30. BMPs: Year-round. Enforcement: Public Works.

Sediment discharge to storm drains or Dry Creek: stop-work, cleanup costs, state water board fines up to $10,000/day under the Porter-Cologne Act.

Coastal Development

Coastal development rules do not apply to Clovis. Clovis is an inland Central Valley city in Fresno County, roughly 170 miles from the Pacific coast, and falls entirely outside California Coastal Act jurisdiction. No Coastal Development Permit requirements attach to any construction in Clovis.

Key details: Coastal Zone: Not applicable. Location: Inland Central Valley. Distance to Coast: ~170 miles. CCC Jurisdiction: None. Applicable Law: CEQA & local grading rules.

Not applicable — no Coastal Act jurisdiction exists in Clovis. Environmental violations instead prosecuted under CEQA, local grading ordinances (Clovis Municipal Code Title 6), and Regional Water Board NPDES/waste-discharge orders with civil penalties up to $10,000/day under Water Code §13385.

The rules around coastal development in Clovis lean permissive, but that does not mean anything goes.
