Description: This inundation map for the regulatory floodway was generated by CENWP-EC Floodplain Management Services Program using the 2025 FPMS hydraulic model of Lookingglass Creek. HEC-RAS hydraulic models have several components including a terrain model, numerical grid, hydraulic roughness characterization, hydraulic structures, boundary and initial conditions, and computational settings. For more information on Hydraulic Model characterization, see the 2025 Lookingglass Creek Flood Study Hydraulics Report
