Summary
Ventura requires a flood area development permit before any construction or development starts in a mapped special flood hazard area, or in a locally known area with a history of flooding. Municipal Code Section 12.440.010 makes this permit mandatory in addition to any other city permit, and the floodplain administrator reviews it against Chapter 12.430 standards.
A flood area development permit shall be obtained before construction or development begins within any area identified on the floodplain insurance rate map as being within a special flood hazard area and within a locally known area that has known flooding. Such permit shall be in addition to any other permits required by this code.

Full Breakdown
440, Flood Area Development Permits, is the gate the city uses to control building inside its floodplain. 010 states the permit requirement flatly: a flood area development permit has to be obtained before construction or development begins within any area identified on the flood insurance rate map as a special flood hazard area, and also within any locally known area that has a documented history of flooding, even if it is not on the FEMA map. That permit is required in addition to, not instead of, any other permit the project needs.
020, has to include scaled plans showing the site's elevation and everything within 300 feet, spot elevations at the building corners, foundation design detail including any crawl-space flood vents, and engineering data showing the project will not measurably raise the base flood elevation. 030 requires an application fee set by city council resolution to cover the administrator's review costs. 430 floodplain standards, that the development will not raise the base flood water surface elevation by more than one-tenth of a foot at any point, and that the building site is reasonably safe from flooding.
070 then bars the city from issuing a certificate of occupancy until a registered civil engineer certifies the finished construction complies with those standards in all respects.
Violations & Fines
Starting construction or development in a special flood hazard area or a locally known flood-prone area without the Section 12.440.010 permit exposes the project to a stop-work order and denial of occupancy. The city will not issue a certificate of occupancy under Section 12.440.070 until a registered civil engineer certifies compliance with the Chapter 12.430 floodplain development standards, so unpermitted work effectively cannot be closed out or occupied.
