Services - Floodplain Analysis and FEMA Permitting

JEWELL Engineering has extensive experience in all aspects of hydrologic and hydraulic modeling using HEC-HMS for flood magnitude analyses and HEC-RAS for water surface profiles. The Federal Emergency Management Agency (FEMA) and North Carolina Floodplain Mapping Program (NCFMP) manage and enforce the provisions of the National Flood Insurance Program in North Carolina, and we work regularly with FEMA and NCFMP staffs to satisfy permitting requirements. JEWELL uses ArcGIS® mapping software, in accordance with FEMA practices, to document floodplain revisions. Our experience includes the following types of FEMA permitting: Conditional Letters of Map Revision (CLOMR), Letters of Map Revision (LOMR), Letters of Map Revision due to Fill (LOMR-F), Letters of Map Amendment (LOMA) and No-Rise Certifications.
