![]() ![]() High-Risk Advisory Zones (Advisory A, Updated AE, and Preliminary NFHL – orange colored zones) are non-regulatory flood zones and not shown on the FIRM however, future FEMA Flood Studies most likely will incorporate these advisory zones on the official FIRM. The Flood Tool displays the primary National Flood Hazard Layers (NFHL) on FEMA Flood Insurance Rate Maps (FIRM). to 1 ft.įlood layers encompass information about flood hazards and mitigating flood risks. Elevation contour intervals at the highest zoom levels vary from 10 ft. Reference layers are generalized and more detailed at zoomed-out and zoomed-in scales, respectively, with all layers displayed at the largest zoom-in scale of 1:282. Other reference layers include the WVDOT roads, hydrography, watersheds, and elevation contours. The WV Property Search Tool is a companion application of the WV Flood Tool that allows users to perform advanced search and filter queries on all property assessment records. Detailed parcel assessment web reports display building information for all primary and secondary structures located in a single parcel. Important layers for property identification are tax parcels, E-911 addresses, geographic names, and community boundaries. Overlay reference layers consist of vector framework layers. Locally produced data sets such as parcels, E-911 addresses, and leaf-off aerial imagery are integrated at the state level and provided as a shared map service. Counties and local communities are encouraged to incorporate their locally acquired data into the Flood Tool.Users can access more than ten aerial imagery data sets from 1999 to present that vary in resolution from 1 meter to 4 inches. AERIAL IMAGERY base maps are useful for viewing structures and high-resolution pictures of the earth's surface.TOPOGRAPHIC and HILLSHADE base maps are helpful for viewing the terrain.ROAD/STREET base maps are useful for viewing the named features of roads, streams, and other points of interest. ![]() Warning colors denote risk level: high risk (red/orange), moderate risk (yellow).Affords eligible communities CRS credits.Shows effective and advisory flood height values for A or AE Zones using Water Surface Elevation (WSEL) Grids. ![]() Displays ground elevation values with a vertical accuracy range of 10 ft.Multiple ways to zoom to geographic locations: street addresses, tax parcels, coordinates, and place names.Visualizations are easier for non-technical users to understand risks to their property in feet of water rather than comprehending the base flood elevation. Renders 3D Flood Visualizations from the base flood water depth and building type.Allows floodplain managers to print flood determination information required for floodplain permits and record keeping.Presents three different cartographic representations of flood zones.Links specific areas of the map to online FEMA-issued maps, hydraulic models, flood profiles, building-level flood risk assessments, external map viewers, detailed property assessment reports, and local floodplain manager contact.Displays in the Flood Query Results Panel comprehensive information about the identified flood hazard (flood zone, flood height, flood depth), ground elevation, geographic location (watershed name, stream name/flood source, parcel identifier, site address, x-y coordinates), and community information.EXPERT View and RISK MAP View are for more advanced users who are familiar with FEMA's official flood maps and mitigation programs for flood risk mapping, assessment, and planning (RISK MAP).PUBLIC View allows the general public to obtain quick and easy flood hazard determinations of identified locations.These Views support FEMA’s NFIP/CRS and Risk MAP Programs. The WV Flood Tool has three customized map views: PUBLIC, EXPERT, and RISK MAP.The WV Flood Tool operates on both desktop computers and mobile phones. Includes the best available flood mapping data from FEMA and other approved sources and incorporates maps/background and reference layers (aerial photos, roads, elevation contours, addresses, parcels, stream names, etc.) from federal, state, local, and commercial sources. ![]() Features Best Available Flood Reference Data ![]()
