No person, firm, corporation, or governmental body not exempted by law shall commence any development in the floodplain without first obtaining a development permit from the zoning administrator. The zoning administrator shall not issue a development permit if the proposed development does not meet the requirements of this chapter.
A. The application for development permit shall be accompanied by:
1. Drawings of the site, drawn to scale showing property line dimensions;
2. Existing grade elevations and all changes in grade resulting from excavation or filling;
3. The location and dimensions of all buildings and additions to buildings;
4. The elevation of the lowest floor (including basement) of all proposed buildings subject to the requirements of section 11-1-7 of this chapter;
5. Cost of project or improvements as estimated by a licensed engineer or architect. A signed estimate by a contractor may also meet this requirement.
B. Upon receipt of an application for a development permit, the zoning administrator shall compare the elevation of the site to the base flood elevation. Any development located on land that can be shown by survey data to be higher than the current base flood elevation and which has not been filled after the date of the site's first flood insurance rate map is not in the floodplain and therefore not subject to the requirements of this chapter. Conversely, any development located on land shown to be below the base flood elevation and hydraulically connected, but not shown on the current flood insurance rate map is subject to the provisions of this chapter. The zoning administrator shall maintain documentation of the existing ground elevation at the development site and certification that this ground elevation existed prior to the date of the site's first flood insurance rate map identification.
