Summary
Any construction or development in Lakewood's FEMA-mapped AR flood hazard zone needs a floodplain development permit before work begins. Municipal Code Section 8033 requires an application showing elevations, floodproofing certifications, and any watercourse alteration, reviewed by the City's Floodplain Administrator, who under Section 8033.1 is the Director of Community Development, before ground is broken.
A development permit shall be obtained before any construction or other development begins within any area of special flood hazard established in Section 8032.1. Application for a development permit shall be made on forms furnished by the Floodplain Administrator and may include, but not be limited to: plans in duplicate drawn to scale showing the nature, location, dimensions and elevation of the area in question; existing or proposed structures, fill, storage of materials, drainage facilities; and the location of the foregoing. Specifically, the following information is required: A. Proposed elevation in relation to mean sea level, of the lowest floor (including basement) of all structures in Zone AR (with base flood depth), elevation of highest adjacent grade and proposed elevation of lowest floor of all structures; or B. Proposed elevation in relation to mean sea level to which any nonresidential structure will be floodproofed, if required in Section 8034.1.C.3; and C. All appropriate certifications listed in Section 8033.2.D. of this Regulation; and D.
