. . CHAPTER 4 FLOODPLAIN ADMINISTRATION AND .ELlNEATION ~ECTION 3.0 FEMA MAP REVISIONS COLORADO STATEWIDE DRAINAGE AND FLOODPLAIN MANAGEMENT CRITERIA MANUAL 3.3 LETTER OF MAP AMENDMENT ILOMAl The regulatory Special Flood Hazard Areas (SFHAs) designated by FEMA are determined as a result of engineering studies utilizing FEMA approved floodplain analysis methods and topographic maps. Depending on the accuracy of physical features and elevations shown on the topographic maps used in their studies, some properties that are naturally (or by fill placed prior to the FEMA original study) at or above the 100-year flood elevation might be incorrectly shown within the SFHA. In such a case, the property owner can request FEMA to issue a LOMA to remove his or her property from the SFHA. The applicant should prepare a request for LOMA submittal including the required property and elevation information and FEMA forms MT-1 or MT-EZ. Detailed LOMA submittal requirements are outlined in the FEMA publications referenced in Section 3.1, Chapter 4 and the FEMA forms. A request for LOMA can be submitted for a single lot/structure using Form MT-EZ or multiple lots/structures using Form MT-1. Since a LOMA essentially is a correction of previous mapping errors, there is no FEMA review fee for a LOMA request. The following is a list of general LOMA submittal requirements: . FEMA forms - MT-1 or MT-EZ . Property information - a copy of recorded Plat Map or recorded deed and other map that shows the property boundary and physical features (streets, buildings, drainageways, etc.) surrounding the property . Lot and/or structure elevations certified by a licensed Professional Engineer or Land Surveyor Since a LOMA essentially is a correction of previous mapping errors, there is no FEMA review fee for a LOMA request. For a lot to be removed from the SFHA, the lowest lot ground elevation must be at or above the 100- year flood elevation. For a structure to be removed, the lowest floor elevation (including basement and/or crawl space) and the lowest adjacent ground touching the structure must be at or above the 1 DO-year flood elevation. An Elevation Information or Elevation Certificate Form for the property must be filled out and certified by a Professional Civil Engineer or a Land Surveyor licensed to practice in the State of Colorado. FEMA compares the certified elevations provided in the form with the effective 100-year flood elevation to determine if the subject property can be removed from the SFHA. For a lot to be removed from the SFHA, the lowest lot ground elevation must be at or above the 100-year flood elevation. For a structure to be removed, the lowest floor elevation (including basement and/or crawl space) and the lowest adjacent ground touching the structure must be at or above the 100-yearflood elevation. The issuance of a LOMA officially removes the subject lot and/or structure from the FEMA SFHA, eliminating the FEMA's flood insurance requirement. However, it should be noted that some lending institutions might still require purchase of flood insurance regardless of the FEMA flood hazard zone designation. Unless the entire lot is elevated at least one (1) foot above the 100-year base flood elevation (BFE) or AUGUST 2002 FEMA MAP REVISIONS CH4-305
