§ 3-21. Letter of Map Change.

(a) Scope of section.

This section applies to any property owner requesting mapping changes.

(b) Letter of Map Change.

A Letter of Map Change is an official FEMA determination, by letter, that amends or revises an effective Flood Insurance Rate Map or Flood Insurance Study.

(c) Letter of Map Amendment (LOMA).

A Letter of Map Amendment is an amendment based on technical data showing that a property was incorrectly included in a designated special flood hazard area. A LOMA amends the current effective Flood Insurance Rate Map and establishes that a specific property or structure is not located in a special flood hazard area.

(d) Letter of Map Revision (LOMR).

A Letter of Map Revision is a revision based on technical data that may show changes to flood zones, flood elevations, floodplain and floodway delineations, and planimetric features. A Letter of Map Revision Based on Fill (LOMR-F), is a determination that a structure or parcel of land has been elevated by fill above the base flood elevation and is, therefore, no longer exposed to flooding associated with the base flood. In order to qualify for this determination, the fill must have been permitted and placed in accordance with the community's floodplain management regulations.

(e) Conditional Letter of Map Revision (CLOMR).

A Conditional Letter of Map Revision is a formal review and comment as to whether a proposed flood protection project or other project comply with the minimum NFIP requirements for such projects with respect to delineation of special flood hazard areas. A Conditional Letter of Map Revision Based on Fill (CLOMR-F) is a determination that a parcel of land or proposed structure that will be elevated by fill would not be inundated by the base flood if fill is placed on the parcel as proposed or the structure is built as proposed. A CLOMR does not revise the effective Flood Insurance Rate Map or Flood Insurance Study; on submission and approval of certified as-built documentation, a Letter of Map Revision may be issued by FEMA, to revise the effective FIRM.

(f) Issuance of permits.

If a proposed development is contingent upon a map change, no permits will be issued for the development until the Letter of Map Revision (LOMR) has been issued by FEMA. The proposed development must be compliant with all pertinent requirements of Division I of Article 7.
