Permit applications shall comply with the City of Mesquite Engineering Design Manual.
Full Breakdown
Mesquite regulates floodplain construction through Chapter 11, Article V, the city's Stormwater and Flood Protection Ordinance. Anyone building, placing fill, siting a manufactured home, or substantially improving a structure in the design-flood floodplain must first obtain a development permit, and the application must comply with the City of Mesquite Engineering Design Manual. The manual, not the code text, fixes the required finished-floor elevation above base flood elevation. The City Manager acts as floodplain administrator and records the lowest habitable floor elevation of every new or improved structure; the City Engineer handles technical review. Violations are misdemeanors, each day a separate offense.
Violations & Fines
Building, filling, or improving in the floodplain without a development permit, or occupying a structure with no FEMA elevation certificate on file, is a misdemeanor; each day the violation continues is a separate offense.
