Your specific zone determines insurance cost, build elevation, and permit requirements in Santa Maria, CA.

Summary

Any construction or development inside a mapped special flood hazard or mudslide area in Santa Maria needs a development permit from the floodplain administrator before work begins, under Municipal Code Section 9-68.201. The Director of Community Development administers the program.

Application for a development permit shall be made on forms furnished by the floodplain administrator and may include, but not be limited to, plans in duplicate drawn to scale showing the nature, location, dimensions and elevation of the area in question; existing or proposed structures, fill, storage of materials, drainage facilities; and the location of the foregoing.

Full Breakdown

Chapter 9-68 implements the City's participation in the National Flood Insurance Program under Government Code Sections 65302, 65560, and 65800. 107, which adopts the 1988 Flood Insurance Study and FIRM maps on file at the Community Development Department, 110 South Pine, and Public Works, 810 West Church Street. 203(d), and a description of any watercourse alteration. 203 to confirm all other state and federal permits are obtained, the site is reasonably safe from flooding, and the development will not raise the base flood water surface elevation by more than one foot cumulatively.

108 makes it unlawful to construct, locate, extend, convert, or alter any structure or land in these areas without full compliance with the chapter, and separately empowers the City Council to take lawful action to prevent or remedy a violation beyond the misdemeanor penalty.

Violations & Fines

Building or developing in a mapped special flood hazard or mudslide area without the Section 9-68.201 development permit is a misdemeanor under Section 9-68.108. The City can also pursue any other lawful enforcement action to prevent or remedy the violation, and a structure lacking required elevation certificates is presumed noncompliant until documentation is provided.
