Summary
Rancho Cordova requires a floodplain development permit before any grading, filling, or construction in a mapped flood hazard area. The floodplain administrator reviews every application against the city's flood provisions and the building code before work can begin, and unpermitted work is a misdemeanor.
Any person, owner or authorized agent who intends to conduct any development in a flood hazard area shall first make an application to the floodplain administrator and shall obtain the required permit for floodplain development. No permit shall be issued until compliance with the requirements of these regulations and all other applicable codes and regulations has been satisfied. No building permit shall be issued based on Conditional Letters of Map Revision issued by FEMA.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: rev 4660102; v2 updated 2026-03-02; through 03-02-2026).
Full Breakdown
120 must first apply to the floodplain administrator and obtain a floodplain development permit; no building permit can rely on a FEMA Conditional Letter of Map Revision. 320 must include a legal description of the site, the proposed use and occupancy, a site plan and construction documents with grading and filling plans, and the valuation of the work, and must be accompanied by a fee set by city council resolution and adjusted every January, billed at the actual hourly cost of city staff plus overhead.
350 if work does not start within 180 days of issuance or is suspended for 180 days, though the floodplain administrator may grant extensions of up to 180 days each unless FEMA has since revised the Flood Insurance Rate Map for the site.

Violations & Fines
Development performed without an issued floodplain development permit, or in conflict with the permit issued, is a violation under RCMC § 16.96.710, and a structure lacking documentation of its lowest-floor elevation or other required certifications is presumed noncompliant until the missing paperwork is filed. Violating these regulations is a misdemeanor. The floodplain administrator may serve a notice of violation or a stop-work order on the property owner, the owner's agent, or whoever is doing the work under § 16.96.720, and anyone who keeps working after being served, other than to correct the violation, faces further penalties under § 16.96.730.
