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

060. 070 ties that jurisdiction to specific federal mapping: the areas of special flood hazard identified by FEMA in the Flood Insurance Study for the City of Rohnert Park, dated June 1, 1981, together with its accompanying Flood Insurance Rate Maps and Flood Boundary and Floodway Maps of the same date and all subsequent amendments and revisions, are adopted by reference as part of the chapter and are kept on file at city hall. The city manager serves as floodplain administrator, granting or denying development permits and reviewing whether permit requirements are satisfied, whether other required state and federal permits have been obtained, whether the site is reasonably safe from flooding, and whether a proposed development would raise the base flood water surface elevation by more than one foot anywhere in the city.

150 is required before any construction or other development, including manufactured homes, within a mapped area of special flood hazard, and the applicant must submit scaled plans showing existing and proposed grading, drainage, utilities, the regulatory floodway if applicable, and the base flood elevation. Appeals from a floodplain administrator decision go to the city council, filed in writing with the city clerk within ten days. Violation of the chapter, including violation of any permit condition, is an infraction, and the city council retains authority to take lawful action to prevent or remedy any violation.
