Sec. 8-28. - Specific Standards.
A. Residential Construction. New construction and substantial improvements of any residential structure must have the lowest floor (including basement) elevated a minimum of 2 feet above the base flood elevation as established by Atlas 14, Vol. 11, Texas, 1.5 feet above adjacent natural ground, or 1 foot above top of curb, whichever is the higher elevation as indicated in Section 8.3.9. A registered professional engineer, architect or land surveyor will submit a certification to the Floodplain Administrator that the standard of this subsection is satisfied.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Land Development Code: Supplement 14 | Code of Ordinances: Supplement 55).
Full Breakdown
5 feet above adjacent natural ground, or 1 foot above the top of curb, whichever produces the higher elevation, and a registered professional engineer, architect, or land surveyor must certify compliance to the Floodplain Administrator. Nonresidential structures face the same elevation choice or must be flood-proofed watertight from at least 1 foot above the base flood elevation down to the depth of the facility, certified by a licensed engineer or architect. ' Manufactured homes placed in Zones A, AH, and AE face the identical 2-foot-above-BFE elevation rule under Section 8-28(D), and critical facilities must sit a minimum of 2 feet above the 100-year base flood elevation under Section 8-32.
The Chapter was substantially rewritten by Ordinance No. 1979 in December 2014 and further amended by Ordinance No. 2248 in November 2021 to sharpen the freeboard and certification language.
Violations & Fines
Failing to meet the freeboard elevation or building without the required certification is enforced under Section 8-37 as a misdemeanor requiring an intentional, knowing, or reckless culpable mental state, punishable under Section 1-7 of the Code of Ordinances, with each day of continued violation a separate offense; the Floodplain Administrator may also issue a stop-work order under Section 8-39 or revoke the development permit under Section 8-40.
