How are inspections scheduled?
Submit the development application to Floodplain Administration at 211 S. Ann Street, Suite 301, Port Lavaca, or contact 361-553-4455. AE/VE work requires the specified elevation, anchoring, utility, and flood-opening documentation; a finished-construction Elevation Certificate is due within 60 days. Utility connections cannot be made until the Floodplain Administrator approves compliance. OSSF permits and inspections are coordinated through a TCEQ-licensed professional installer and the Calhoun County Designated Representative.
Which codes and exemptions should I review?
Calhoun County's development permit requires compliance with the Calhoun County Flood Damage Prevention Order, Texas Building and Windstorm regulations, FEMA/NFIP requirements, and applicable AE/VE flood-zone standards. These include anchoring, flood-resistant materials, utilities above the base flood elevation, elevation certificates, flood openings in AE zones, pile/column foundations in VE zones, and restrictions on fill and construction seaward of mean high tide. The county's OSSF program operates through its County Designated Representative under Texas Health and Safety Code Chapter 366 and 30 TAC Chapter 285; no specific 2026 ICC edition is published. No county list of cosmetic or minor-work exemptions is published. The official application covers new construction, repairs, additions, remodeling, moving structures, utilities, grading/fill, and other development in regulated flood areas; approval requirements depend on the flood zone and applicable order. Calhoun County's local OSSF authority must be consulted for any state acreage or emergency exemption because no county exemption list was published.
