Full Breakdown

Hanford Municipal Code Section 15.52.130 requires a development permit before any construction or other development begins within an area of special flood hazard, as mapped under the FEMA flood insurance study adopted in Section 15.52.070. Applicants must submit scaled plans showing the elevation of the lowest floor of proposed structures, and, for the AO zone, the elevation of the highest adjacent grade, plus a description of any watercourse alteration. The community development director, acting as floodplain administrator under Section 15.52.140, reviews and grants or denies these permits. This applies within Hanford's city limits in Kings County, not unincorporated county land.
