Estimated Base Flood Elevation (BFE) viewer for property owners, community officials and land developers to identify the flood risk (high, moderate, low), expected flood elevation and estimated flood depth near any property or structure within watersheds where Base Level Engineering has been prepared.
7 lip 2020 · The base flood is the national standard used by the National Flood Insurance Program (NFIP) and all Federal agencies for the purposes of requiring the purchase of flood insurance and regulating new development. Base Flood Elevations (BFEs) are typically shown on Flood Insurance Rate Maps (FIRMs). National Flood Insurance Program Requirements
Heavy rains, poor drainage, and even nearby construction projects can put you at risk for flood damage. Flood maps are one tool that communities use to know which areas have the highest risk of flooding. FEMA maintains and updates data through flood maps and risk assessments.
FEMA GIS supports the emergency management community with world-class geospatial information, services, and technologies to prepare for, protect against, respond to, recover from and mitigate against all hazards.
Providing additional flood hazard datasets, like water surface elevation and flood depth rasters , delivers additional information that reinforces the variability of flood hazards within a designated floodplain and supports community requests for a source to determine a Base Flood Elevation in Zone A areas.
Developments in excess of 50 lots or 5 acres are required to determine a Base Flood Elevation (BFE) - 44CFR60.3(b)(3). This document will help you to determine a BFE for sites that are outside of a designated floodplain extent using Base Level Engineering (BLE) data and the BFE Interpolate Tool.
base flood elevations are identified by numbers representing the elevation. The dark shaded area outside the floodway is the 1percent chance - floodplain or Special Flood Hazard Area and the light shaded areas (labeled Zone X) are the 0.2 - percent chance floodplain.
