El Cajon, CA Environmental Rules: Erosion Control (2026)

160(A) requires an erosion and sediment control plan for all construction-activity permit applications, including grading permits, designed to limit erosion on disturbed portions of a property and stop soil from washing onto adjacent land or into streets, storm drains or drainage ways. Subsection (B) requires the plan to be reviewed and approved by the city engineer as part of the construction permit application, to comply with the state's general construction storm water permit where applicable, and to list the name, address and 24-hour phone number of the owner and the party responsible for installing and maintaining best management practices, plus the civil engineer who prepared the plan and the location of all proposed erosion, sediment and waste-management control measures.

Subsection (C) sets operating standards: removable protective devices must be in place at the start of construction and by the end of any working day when there's a fifty percent chance or greater of rain within the next 48 hours, and if a developer doesn't install or maintain required controls within two hours of being called at the 24-hour number, the city engineer can send city crews or a contractor to do the work and charge the cost to the developer's deposit. An area is considered inactive, and must be fully protected from erosion, once construction has stopped for 14 or more consecutive days.

Subsection (D) requires dust control on graded or stockpiled material, subsection (E) requires all erosion and sediment control best management practices to stay functional and be inspected before the rainy season and after every major storm, and subsection (F) lets the city engineer halt grading work entirely during the rainy season if erosion or sediment discharge could harm downstream property, drainage courses or storm drains.
