Any grading, clearing, or construction in Menifee that exposes soil must implement Best Management Practices to prevent sediment from leaving the site and entering streets, storm drains, or waterways. Sites disturbing 1 acre or more require state Construction General Permit coverage with a Stormwater Pollution Prevention Plan (SWPPP); smaller sites require a city-approved Erosion and Sediment Control (ESC) plan. The wet-season requirement (October 1 – April 30) triggers heightened BMP standards including stabilized site entrances, silt fences, fiber rolls, hydroseeding, and inlet protection.
Menifee's grading and erosion provisions are inherited from Riverside County Ordinance 457 (Regulating Grading) carried forward at 2008 incorporation, and from MMC Title 7 Article 6 grading standards plus California Building Code Appendix J (Grading), adopted by reference at MMC Title 15. Before any grading permit is issued, the applicant must submit a soils/geotechnical report and an erosion control plan showing temporary BMPs during construction and permanent BMPs after completion. During the rainy season (October 1 to April 30) all denuded slopes must be stabilized within 14 days of inactivity, perimeter sediment controls (silt fence, fiber roll, gravel bag berm) must be in place, and concentrated flows must be directed away from disturbed areas to stabilized outlets. Concrete washout containment is required on all construction sites. The contractor must conduct inspections before predicted rain events of 0.5 inch or more, after each event, and every 24 hours during prolonged storms (per Construction General Permit). Post-construction, slopes steeper than 3H:1V require erosion-control planting/hydroseed and irrigation until permanent vegetation establishes.
Discharging sediment-laden runoff is an MS4 permit violation. Penalties include stop-work orders, daily administrative fines, and forfeiture of grading bonds. Repeat violations may result in CGP termination and direct enforcement by the RWQCB with civil penalties up to $10,000/day plus $10/gallon of unauthorized discharge under Water Code §13385.
