A community's base flood elevations may increase or decrease resulting from physical changes affecting flooding conditions. As soon as practicable, but not later than six (6) months after the date such information becomes available, a community shall notify the Federal Insurance Administrator of the changes by submitting technical or scientific data in accordance with Section 44 of the Code of Federal Regulations (CFR), subsection 65.3. The community may require the applicant to submit such data and review fees required for compliance with this section through the applicable FEMA letter of map change (LOMC) process.
The Floodplain Administrator shall require a conditional letter of map revision prior to the issuance of a floodplain development permit for:
A. Proposed floodway encroachments that increase the base flood elevation; and
B. Proposed development which increases the base flood elevation by more than one foot (1') in areas where FEMA has provided base flood elevations but no floodway.
An applicant shall notify FEMA within six (6) months of project completion when an applicant has obtained a conditional letter of map revision (CLOMR) from FEMA. This notification to FEMA shall be provided as a letter of map revision (LOMR).
The applicant shall be responsible for preparing all technical data to support CLOMR/LOMR applications and paying any processing or application fees associated with the CLOMR/LOMR.
The Floodplain Administrator shall be under no obligation to sign the community acknowledgment form, which is part of the CLOMR/LOMR application, until the applicant demonstrates that the project will or has met the requirements of this code and all applicable state and federal laws.
