Summary
Sandy City regulates development in FEMA-mapped flood hazard areas through its Floodplain Overlay Zone under City Code Chapter 21-16. A Floodplain Development Permit from the Floodplain Administrator is required before new construction, substantial improvement, or repair of substantial damage in a special flood hazard area, and development is barred outright in the regulatory floodway absent an engineer's no-rise certification.
Sandy City elects to comply with the requirements of the National Flood Insurance Act of 1968 (P.L. 90-488, as amended), to join the National Flood Insurance Program (NFIP), and to implement and enforce the requirements and regulations of the NFIP through a floodplain overlay zone...This floodplain overlay zone includes all special flood hazard areas (SFHAs) identified by the Federal Emergency Management Agency (FEMA) and shown on the City's effective flood insurance rate map (FIRM) or flood boundary floodway maps; and all areas identified by the City as having an inherent risk of flooding as documented and supported using best available data. The most restrictive data shall apply if the FIRM, flood boundary floodway maps, Flood Insurance Study (FIS) or best available data differ...The regulations of this chapter shall be supplemental to, and not in lieu of, the applicable zoning provisions of the zone in which the land is located...In cases of conflict, the most restrictive provisions shall govern.
Full Breakdown
Sandy City's Floodplain Overlay Zone, adopted at City Code Chapter 21-16, implements the National Flood Insurance Program inside every Special Flood Hazard Area shown on the City's effective Flood Insurance Rate Map, FEMA's Flood Insurance Study for Salt Lake County, and the City's flood boundary and floodway maps (§§ 21-16-1 through 21-16-3). The rules are supplemental to the underlying zoning district, and where the flood ordinance and zoning conflict, the more restrictive provision controls (§ 21-16-2). The Public Works Director or a designee serves as Floodplain Administrator (§ 21-16-5) and reviews every Floodplain Development Permit application, confirms federal and state approvals such as Clean Water Act Section 404 and Endangered Species Act clearances, and keeps elevation and floodproofing certifications on file for public inspection (§ 21-16-6); altering a watercourse also requires a separate permit from the Salt Lake County Division of Flood Control and Water Quality.
00 foot without a FEMA conditional map revision (§ 21-16-8). An owner who cannot meet the standard can ask the Planning Commission for a special exception, but only for a lot of one-half acre or less surrounded by existing sub-BFE structures, or for a listed historic structure, and only on findings that the exception is the minimum necessary and will not raise flood heights or create a public-safety hazard (§ 21-16-11). Sandy's Jordan River corridor carries additional Salt Lake County liquefaction-hazard study requirements layered on top of the citywide rules (§ 21-16-15).
Violations & Fines
Section 21-16-16 lets the Floodplain Administrator issue an immediate written stop-work order for any activity that violates the chapter, stating the reason and the conditions for resuming work; continuing work after that order is served exposes the responsible party to enforcement penalties under state or local law. Any structure missing the elevation certificate or other compliance documentation required by 44 CFR 60.3 is presumed to be in violation until the paperwork is produced.
