Fremont requires erosion and sediment control BMPs on all construction sites and mandates year-round and wet-season plans for hillside grading projects.
All construction sites in Fremont, regardless of size, must install and maintain erosion and sediment control Best Management Practices (BMPs) per the California Stormwater BMP Handbook and the Municipal Regional Stormwater Permit. Sites 1 acre or larger must obtain state coverage under the Construction General Permit and prepare a SWPPP. Between October 1 and April 30 (wet season), all disturbed soils must be stabilized with erosion control blankets, hydroseed, or equivalent. Fremont Building Inspection and Public Works staff inspect sites and can issue stop-work orders for non-compliance. Hillside properties in the Hillside Combining District require heightened geotechnical and drainage review.
