Full Breakdown

Lake Havasu City administers its own floodplain management program under City Code Chapter 8.22, Flood Damage Prevention, enacted under the authority the Arizona Legislature granted in A.R.S. § 48-3610 and § 48-3603. The Operations Department Director, acting as Floodplain Administrator, reviews every development permit application under § 8.22.170 and § 8.22.180 to confirm the site is reasonably safe from flooding and that the project will not raise the base flood elevation more than one foot at any point where a floodway has not been designated.

Applicants must submit plans in duplicate showing the proposed lowest habitable floor elevation relative to mean sea level; in Zone AO, the existing grade and proposed lowest floor elevation; and, for any nonresidential structure that will be flood-proofed instead of elevated, certification by a registered professional engineer or architect that the flood-proofing meets the criteria in § 8.22.190.C.3. Any watercourse alteration or relocation proposed as part of the project must also be described in the application. The Floodplain Administrator keeps elevation certifications, flood-proofing certifications and floodway encroachment certifications on file for public inspection and reports variances issued under § 8.22.260 to FEMA in a biennial report.

Development inside the Colorado River Floodway carries an added layer of review: proposals there must be concurred with by the Bureau of Reclamation under § 8.22.290 before the city will issue a permit. All development after August 8, 1973 that does not comply with Chapter 8.22 is declared a public nuisance per se under § 8.22.130 and may be abated by the city.

Violations & Fines

Developing or building in a special flood hazard area without the required permit, or otherwise violating Chapter 8.22, is a misdemeanor under § 8.22.150, with each day a violation continues charged as a separate offense. The Floodplain Board can also order abatement of the violation within 30 days of the Floodplain Administrator's report under § 8.22.140, and unpermitted development declared a public nuisance under § 8.22.130 can be abated, enjoined or restrained by the city.

Frequently Asked Questions

Do I need a permit to build in a flood zone in Lake Havasu City?

Yes. City Code § 8.22.170 requires a development permit before any construction or development begins in an area of special flood hazard.

What happens if I build without a flood zone permit?

Building without the required permit is a misdemeanor violation of Chapter 8.22 under § 8.22.150, and each day the violation continues counts as a separate offense.
