Summary
Santa Clarita requires a development permit before any construction, fill, grading or manufactured home placement in a FEMA-mapped special flood hazard area. The Director of Public Works, acting as Floodplain Administrator, reviews every application under Chapter 10.06 before work can start.
No structure or land shall hereafter be constructed, located, extended, converted, or altered without full compliance with the terms of this chapter and other applicable regulations. Violation of the requirements (including violations of conditions and safeguards established in connection with conditions) shall constitute a misdemeanor, and shall also be considered a municipal code violation subject to fines and penalties as provided for in Chapter 23.20.
Full Breakdown
06 of the Santa Clarita Municipal Code applies to "all areas of special flood hazards within the jurisdiction of the City of Santa Clarita," based on FEMA's Flood Insurance Study dated September 29, 1989 and the accompanying Flood Insurance Rate Maps, plus the Los Angeles County Floodway Maps where FIRMs do not show a floodway. 20. 040(C) requires a development permit, obtained on City forms, for any construction or development including manufactured homes within a special flood hazard area; the application must include scaled plans showing elevations, proposed fill and drainage, the location of the regulatory floodway when applicable, and the proposed elevation of the lowest floor.
The Floodplain Administrator (the Director of Public Works) reviews each permit to confirm the site is reasonably safe from flooding and that cumulative development will not raise the base flood water surface elevation more than one foot anywhere in the City. 040(D), on top of any other penalty. 040(E). The FIS, FIRMs and county floodway maps are kept on file at the Office of Public Works, 23920 Valencia Boulevard, Suite 140.
Violations & Fines
Building or developing in a mapped flood hazard area without a permit is a misdemeanor and a separate municipal code violation carrying fines under Chapter 23.20. Starting work before a permit issues triggers a mandatory investigation fee equal to double the normal review fee, regardless of whether a permit is later granted, and does not excuse compliance with the rest of the chapter.
