Huntington Park, CA Environmental Rules: Flood Zones (2026)

Chapter 19 of Title 8, the Floodplain Management Regulations of the City of Huntington Park, took effect December 4, 2024 under Ordinance 2024-04. It works together with the California Building Standards Code. Section 8-19.102-2 adopts Flood Insurance Rate Map Number 06037C1805F, effective 9/26/2008, with later amendments, as the basis for flood hazard areas. The maps and studies are on file at the City of Huntington Park, 6500 Miles Ave. Section 8-19.103-1 designates the Public Works Director as Floodplain Administrator.

The regulations reach more than buildings. Section 8-19.102-1 covers subdivision of land, filling, grading and other site improvements, utilities, manufactured homes, recreational vehicles, tanks, temporary structures and storage, utility and miscellaneous Group U buildings, and flood control projects.

The permit application is written, on a form from the Floodplain Administrator. It must describe the development and the land by legal description or street address, state the intended use and occupancy and the valuation of the work, carry a site plan and construction documents including grading, excavation and filling plans, and be signed by the applicant or authorized agent. No building permit is issued based on a FEMA Conditional Letter of Map Revision.

Substantial improvement means work whose cumulative cost over a five-year period equals or exceeds 50% of the structure's market value, and it triggers flood resistant construction rules. Fill or regrading in a floodway is not authorized unless the encroachment analysis shows no increase in the base flood level. Recreational vehicles must stay for less than 180 consecutive days or be fully licensed and ready for highway use, and temporary structures are limited to less than 180 days. Section 8-19.101-6 warns that larger floods can and will occur.
