6.4A Page 2 G. Base Flood Elevation changes due to physical alterations: 1. Within six months of information becoming available or project completion, whichever comes first, the floodplain administrator shall submit or assure that the permit applicant submits technical and/or scientific data to FEMA for a Letter of Map Revision (LOMR}. 2. All LOMR's for flood control projects are approved prior to the issuance of building permits. Building Permits must not be issued based on Conditional Letters of Map Revision (CLOMR's). Approved CLOMR's allow construction of the proposed flood control project and land preparation as specified in the "start of construction" definition. Revision of section 41.19. Standards for Subdivisions, paragraph B to read: B. All subdivision plans will provide the elevation of proposed structures} and pad(s). If the site is filled above the base flood elevation, the as-built information for the lowest floor elevation, pad elevation, and the lowest adjacent grade for each structure shall be certified by a registered civil engineer or licensed land surveyor and provided as part of an application for a Letter of Map Revision based on Fill (LOMR-F) to the Floodplain Administrator and FEMA. A LOMR is FEMA's modification to an effective FIRM, or Flood Boundary and Fooodway Map (FBFM), or both. LOMRs are generally based on the implementation of physical measures that affect the hydrologic or hydraulic characteristics of a flooding source and thus result in the modification of the existing regulatory floodway, the effective Base Flood Elevations (BFEs), or the SFHA. A LOMR-F is FEMA's modification of the SFHA shown on the FIRM based on the placement of fill outside the existing regulatory floodway. The Floodplain Administrator is defined in the ordinance as the position established to administer and enforce the Floodplain Management Ordinance, and according to Section 41.14, Designation of the Floodplain Administrator, the City Engineer is appointed to that position. The "start of construction" definition pertaining to land preparation is stated in Section 41.6, Definitions, as "land preparation such as clearing, grading and filling, installation of streets and/or walkways, excavation for a basement, footings, piers or foundations or the erection of temporary forms, installation on the property of accessory buildings such as garages or sheds not occupied as dwelling units or not part of the main structure." The lowest floor elevation is defined in Section 41.6, Definitions, as "the lowest floor of the lowest enclosed area, including basement." The pad elevation, for slab-on-grade construction, is the elevation of the foundation pad. ALTERNATIVES Council may choose not to amend the ordinance, which will result in the City being non- compliant with NFIP.
