§ 38-47. Letters of map revision.

(a)

Existing structure or structures. Upon the determination of the floodplain administrator that the ground elevation of a property is not in accordance with the approved FIRM, a property owner may apply to FEMA for a letter of map revision (LOMR) or letter of map revision—Fill (LOMR-F) in accordance with 44 CFR Chapter 1, Section 72. Such a determination shall be based on a professional survey and the hydraulic computer model (HEC-2 or HEC-RAS) used by a professional engineer to define the SFHA. All supporting documentation shall be submitted to the floodplain administrator for review and approval prior to submission to FEMA for review and approval.

(b)

Proposed structure or structures. Upon the determination of the floodplain administer that property currently indicated in a SFHA could be removed from the SFHA through modifications of the floodplain as identified on the FIRM, a property owner may apply to FEMA for a conditional letter of map Revision (CLOMR) or conditional letter of map revision—Fill (CLOMR-F) in accordance with 44 CFR Chapter 1, Section 72. Such modifications and the determination shall be based on a professional survey and the hydraulic computer model (HEC-2 or HEC-RAS) used by a professional engineer to define the SFHA. In this instance, the property owner shall not begin construction within the existing floodplain or the area of the proposed floodplain until FEMA issues a CLOMR or CLOMR-F. Additionally, after FEMA's issuance of a CLOMR or CLOMR-F and such modifications have been completed, the property owner shall apply to FEMA for a LOMR or LOMR-F. Such property owner shall not begin any construction of any development in the existing floodplain or proposed floodplain until FEMA has issued the LOMR or LOMR-F.
