To meet National Flood Insurance Program minimum requirements to have flood data reviewed and approved by FEMA, and to ensure that the City of Bellevue's flood maps, studies and other data identified in Section 1329.06 accurately represent flooding conditions so appropriate floodplain management criteria are based on current data, the following map maintenance activities are identified:
(a) Requirement to Submit New Technical Data.
(1) For all development proposals that impact floodway delineations or base flood elevations, the community shall ensure that technical data reflecting such changes be submitted to FEMA within six months of the date such information becomes available. These development proposals include:
A. Floodway encroachments that increase or decrease base flood elevations or alter floodway boundaries;
B. Fill sites to be used for the placement of proposed structures where the applicant desires to remove the site from the special flood hazard area;
C. Alteration of watercourses that result in a relocation or elimination of the special flood hazard area, including the placement of culverts; and
D. Subdivision or large scale development proposals requiring the establishment of base flood elevations in accordance with Section 1329.31.
(2) It is the responsibility of the applicant to have technical data, required in accordance with this Section prepared in a format required for a Conditional Letter of Map Revision or Letter of Map Revision, and submitted to FEMA. Submittal and processing fees for these map revisions shall be the responsibility of the applicant.
(3) The Floodplain Administrator shall require a Conditional Letter of Map Revision prior to the issuance of a floodplain development permit for proposed floodway encroachments that increase the base flood elevation; and proposed development which increases the base flood elevation by more than one foot in areas where FEMA has provided base flood elevations but no floodway.
(4) Floodplain development permits issued by the Floodplain Administrator shall be conditioned upon the applicant obtaining a Letter of Map Revision from FEMA for any development proposal subject to this Section.
