Issues related to Letters of Map Revision (LOMRs) based on fill. A LOMR based on <br />fill is issued when a parcel of land is raised by adding layers of soil so that the finish floor of a <br />building is higher than the adjacent BFE. Since applicants for this type ofLOMR can also contact <br />FEMA directly, the same concerns exist as for a LOMA, that is, the processes of erosion and <br />deposition and the impact force of debris, may still result in damage to the building. <br />3. The perceived flow path issue. Because of the convex cross-slope of many alluvial fans, <br />floodwaters leaving the historical or perceived channel may follow a new direction and inundate <br />areas distant from the channel. The alluvial fan flooding designation enables the inclusion of these <br />
