Summary

Every construction project in Ceres, regardless of size, must run BMPs for erosion and sediment control, soil stabilization, and dewatering whenever soil is disturbed and exposed to storm water.

All construction projects, regardless of size, having soil disturbance or activities exposed to storm water must, at a minimum, implement BMPs for erosion and sediment controls, soil stabilization, dewatering, source controls, pollution prevention measures, and prohibited discharges.2.Any person subject to a construction activity NPDES storm water discharge permit shall comply with all provisions of such permit. Proof of compliance with said permit may be required in a form acceptable to the enforcement official prior to, or as a condition of, a subdivision map, site plan, building permit, grading permit, or development or improvement plan, upon inspection of the facility, during any enforcement proceeding or action, or for any other reasonable cause. Prior to issuance of a construction permit or approval of the proposed improvement plans, for projects subject to the State's current construction NPDES general permit, the WDID number and the SWPPP shall be submitted to the City. For projects with less than an acre of soil disturbance or not subject to the construction general permit, an erosion and sediment control plan ("ESCP") and the ESCP worksheet must be submitted to the City.

Full Breakdown

Ceres Municipal Code Chapter 13.20 requires anyone doing construction to keep pollutants out of the storm water conveyance system. Section 13.20.110(B)(1) is explicit: all construction projects, regardless of size, having soil disturbance or activities exposed to storm water must, at a minimum, implement BMPs for erosion and sediment controls, soil stabilization, dewatering, source controls, pollution prevention, and prohibited discharges. Sites under an acre (below the State's Construction General Permit threshold) instead file a local erosion and sediment control plan (ESCP) with the City; larger sites submit their WDID number and SWPPP. City inspectors, who must be qualified SWPPP practitioners, run pre-disturbance, periodic, and completion inspections keyed to the site's CGP risk rating.

Violations & Fines

Non-storm-water discharges and BMP failures are chapter 13 violations enforceable by notice-and-order-to-abate, administrative citation, or civil action; courts may impose civil penalties up to $10,000 per violation per day (§ 13.23.020).

Frequently Asked Questions

Do small Ceres projects need an erosion control plan?
Yes. Section 13.20.110(B)(2) requires an erosion and sediment control plan (ESCP) and worksheet for any project under an acre that isn't covered by the State's construction general permit.
Who inspects construction sites for erosion compliance in Ceres?
A City inspector who is a qualified SWPPP practitioner (QSP), or working under one, per § 13.20.110(B)(3); inspection frequency scales with the site's CGP risk rating.
