Full Breakdown
Sec. 14-531 applies the city's flood hazard reduction article to all areas of special flood hazard within city jurisdiction, defined by Sec. 14-532 against the FEMA Flood Insurance Study for Nueces County and accompanying flood insurance rate maps dated October 13, 2022. Sec. 14-533 requires a development permit in the floodplain before land is disturbed or a structure altered, and Sec. 14-534 bars locating, altering or changing the use of any structure or land without full compliance. Sec. 14-541 designates the city manager or the manager's designee as floodplain administrator, assisted by a three-person floodplain review committee covering engineering, planning and inspection.
Under Sec. 14-543(a), the application goes to the floodplain administrator on the city's forms, with duplicate scaled plans showing the location, dimensions and elevation of proposed alterations and structures relative to the special flood hazard area; subsection (b) adds elevation data, flood-proofing certification and watercourse-alteration disclosures. Subsection (c) lists ten factors the administrator may weigh in approving or denying the permit, from flood and erosion danger to compatibility with the comprehensive plan, and subsection (d) lets the administrator revoke a permit for misrepresentation or code violations.
Sec. 14-544 sends variance requests to the Construction Trade Advisory and Appeals Board, which may grant relief only on findings of hardship, minimum necessary deviation and no increased flood risk.
Violations & Fines
Sec. 14-557 makes it unlawful to construct, locate, extend, convert or alter any structure or land in the floodplain without full compliance with the article; a conviction is punishable by a fine of not more than $500.00 for each violation, plus all costs and expenses of the case, and the city may still pursue any other lawful remedy to prevent or correct the violation.
