Full Breakdown
Conroe Code sec. 78-82(1) requires every new or substantially improved residential structure in a special flood hazard area to set its lowest floor at least one foot above the base flood elevation shown on the August 18, 2014 Montgomery County FIRM. Nonresidential buildings must match that one-foot freeboard or be dry-floodproofed to the same height. Electrical, heating, ventilation, plumbing, and air-conditioning equipment must also sit one foot above the base flood elevation. A floodplain development permit from the Director of Infrastructure Services (the floodplain administrator) is mandatory, and a registered engineer, architect, or land surveyor must certify the finished-floor elevation.
Violations & Fines
Building without full compliance is a misdemeanor. Each violation draws a fine of up to $500, plus all case costs, and the city council may pursue additional lawful action to remedy the noncompliant structure.
