Full Breakdown

Shenandoah's flood damage protection ordinance sits at Chapter 86, Article II of the Code of Ordinances and applies to every area of special flood hazard within the city's jurisdiction, mapped on the Flood Insurance Study for Montgomery County and Incorporated Areas dated December 19, 1996, and its FIRM/FBFM maps as later revised (Sec. 86-37). The city administrator serves as floodplain administrator (Sec. 86-76) and reviews every development permit application, checking site plans, elevations of the lowest floor, and floodproofing certifications from a registered professional engineer or architect before approving or denying a request (Sec.

86-92). Ten factors guide that decision, including the danger to life and property, the site's access for emergency vehicles in a flood, and whether a floodplain location is even necessary for the proposed use. No structure or land use may change without full compliance (Sec. 86-38), and within the adopted regulatory floodway, encroachments including fill and new construction are flatly prohibited unless engineering analysis shows no increase in flood levels (Sec. 86-135). An owner who believes the floodplain administrator erred can appeal to the city's appeal board, which can grant a variance only on a showing of good cause and hardship, and never within the floodway if it would raise flood levels (Sec.

86-111). Historic structures individually listed on the National Register get separate, more flexible variance treatment. A. Water Code Sec. , which delegated flood-loss regulation to local governments (Sec. 86-32).

Violations & Fines

Violating any provision of the floodplain article is a misdemeanor, punishable on conviction by a fine of up to $200.00, with each day of a continuing violation charged as a separate offense (Sec. 86-42). Beyond the criminal fine, the city may go to court for injunctive relief to stop the violation and to recover a civil penalty under V.T.C.A., Water Code Sec. 16.322, stacking criminal and civil exposure on the same unpermitted fill or structure.

Frequently Asked Questions

Do I need a city permit to fill or grade land in a Shenandoah flood zone?

Yes. Section 86-91 of the Code of Ordinances requires a development permit before any fill, grading, mining, building or land-use change within a mapped area of special flood hazard. Applications go to the city administrator, who serves as floodplain administrator, and must show the elevation of the lowest floor and other site details under Section 86-92 before work can begin.

Who decides whether my property is in Shenandoah's floodplain?

The city administrator, acting as floodplain administrator, applies the Flood Insurance Study for Montgomery County and Incorporated Areas, dated December 19, 1996, and the accompanying FIRM and flood boundary-floodway maps adopted by reference in Section 86-37, interpreting any conflict between a mapped boundary and actual field conditions.

What happens if I build in the floodway without a permit in Shenandoah?

You are guilty of a misdemeanor under Section 86-42, fined up to $200 for each day the violation continues, and the city can also sue for injunctive relief and a civil penalty under state water law. Section 86-135 separately bars most encroachments, including fill, within the adopted regulatory floodway.

Can I appeal a floodplain permit denial in Shenandoah?

Yes. Section 86-111 lets you appeal to the city's appeal board, which can grant a variance only on a showing of good cause and exceptional hardship, and never within the floodway if it would raise flood levels during the base flood discharge.
