Ontario requires active erosion control on all graded sites year-round under OMC Chapter 5 Article VI, with enhanced Best Management Practices from October 1 through April 30 during the rainy season.
Ontario enforces year-round erosion and sediment control under Ontario Municipal Code Chapter 5 Article VI and the California Construction General Permit. Any project disturbing soil must deploy Best Management Practices (BMPs) including silt fences, fiber rolls, gravel bags, stabilized construction entrances, and inlet protection on all downstream storm drains. From October 1 through April 30 (defined wet season per the Santa Ana Regional Water Board) enhanced BMPs are mandatory and exposed slopes must be hydroseeded, covered with straw mulch, or tarped. Tracked-out sediment on public streets must be cleaned by shovel or street sweeper by the end of each workday; washing dirt into a storm drain is a direct violation. Projects over 1 acre must have a Qualified SWPPP Practitioner (QSP) inspect BMPs weekly and before predicted storm events. Noncompliance can trigger stop-work orders and administrative citations up to 10,000 dollars per day. Grading permits issued by Ontario Building and Safety include specific BMP conditions.
