Huntington Park, CA Environmental Rules: Erosion Control (2026)

Section 7-9.09 sits in Chapter 7-9, Stormwater Management and Discharge, of the Huntington Park Municipal Code and applies to all projects undergoing construction in the City of Huntington Park, Los Angeles County.

Subsection (a) is a grading permit gate. No grading permit issues for developments with disturbed areas of five acres or greater unless the applicant shows that a notice of intent to comply with the State Construction Activity Storm Water Permit has been filed and a Storm Water Pollution Prevention Plan has been prepared.

Subsection (b) runs from demolition of an existing structure or commencement of construction until receipt of a certificate of occupancy. During that window, sediment, construction waste and other pollutants, including runoff from equipment and vehicle washing, must stay on the site to the maximum extent practicable. Anything that leaves the site must be removed the same day, and the City Engineer and/or Building Official can require a temporary sediment barrier. Plastic covering is allowed on an emergency basis only, paired with runoff devices that intercept and safely convey the runoff. Excavated soil must be placed to minimize sediment running into the street or onto adjoining properties, and soil piles stay covered until the soil is used or removed. Washing construction or other industrial vehicles adjacent to a construction site is prohibited. Drainage controls are required as needed for the grading and topography, and the listed options are detention ponds, sediment ponds, infiltration pits, dikes, filter berms, ditches, down drains, chutes and flumes.

Subsection (c) lets the City condition a construction permit on reasonable limits on clearing of vegetation, including how long soil can stay bare and, in certain sensitive cases, a ban on bare soil. Subsection (d) points owners and developers to the Construction Best Management Practices Handbook published by the Storm Water Quality Task Force. Fees for plan checking and monitoring are set by City Council resolution under § 7-9.10.
