Full Breakdown

San Angelo adopted floodplain management regulations (Article 12.05) to qualify for the National Flood Insurance Program, as authorized by Texas Water Code Section 16.315. The City Engineer, as Floodplain Administrator, reviews development in FEMA-mapped Special Flood Hazard Areas along the Concho River and its tributaries. New or substantially improved structures in the floodplain must have their lowest floor elevated to or above the base flood elevation, documented with an elevation certificate. Fill, grading, and stream crossings in the floodway are restricted so they do not raise flood levels on neighboring property. Flash flooding on the Concho is a genuine local hazard, and these standards are actively enforced.

Violations & Fines

Building or placing fill in the floodplain without a floodplain development permit exposes the owner to city enforcement, mandatory removal, and loss of flood-insurance eligibility for the structure.

Frequently Asked Questions

How high must a floodplain home be built?

The lowest floor must be at or above the base flood elevation, confirmed by an elevation certificate from a licensed surveyor.
