Notes:

For shapefile, it must be zipped in .zip format.
The .zip file must contain .shp, .shx, .dbf, and .prj files.
The shapefile can't have more than 4,000 point features (or 1,000 line or polygon features) or can't be larger than 10 MB.
More detailed information/limitations can be found here.
For CSV file, the location fields must be as following:
latitude fields:lat, latitude, y, ycenter
longitude fields: lon, long, longitude, x, xcenter
A layer control of added layer is created in the Reference layer list. You can turn on/off and change the transparency.
Click each individual symbol for attribute information.

The web service needs to in HTTPS protocol and in ESRI's RESTful format.
The web service url ends with "MapServer" will be valid url, i.e., https://server-domain/arcgis/rest/services/service-name/MapServer

Flood Height

More Informaton for Flood Height

Advisory Flood Heights (AFH) for Approximate A Zones: The Advisory Flood Height (AFH) is analogous to the flood water surface elevation (WSEL) used in effective FIRMs and represents the elevation above sea level of the surface of the 1% annual chance or regulatory flood in newly modeled areas of approximate study (Zone A) using hydrology and hydraulics (H&H) analysis and the best available elevation data.CAUTION CAUTION!! The advisory flood height should be used with caution in the proximity of a culvert, bridge, flood control structure or other impoundment since stream crossings were not included in the hydraulic analyses for approximate floodplains. Also, if the site is close to the confluence with a larger stream, compare the advisory flood height at the location of interest to the advisory flood height or Base Flood Elevation on the larger stream to determine whether the site is within the backwater influence of the larger stream. More information

Restudy and Non-Restudy AE Zones: To validate base flood elevations refer to the Flood Profiles and Flood Elevation Tables in the FIS Report. Generally, non-restudy redelineated flood height grid values for AE Zones are generated from water surface elevation values of Cross-Section lines and not the BFE line values.

Vertical Datum: The vertical datum of Base Flood Elevations (BFEs) for AE Zones recorded on official FIRMs in West Virginia is NAVD 88, except for the following counties where the FIRMs are referenced to the NGVD 29 Datum: Hampshire, Logan, McDowell, Mercer, Monroe, Ohio, and Putnam. The vertical datum of all Advisory Flood Height values for Approximate A Zones in West Virginia is NAVD 88, except for McDowell County which is NGVD 29. More information

Community

Community Rating System (CRS)

General Description: The Community Rating System (CRS) is a voluntary program for National Flood Insurance Program (NFIP) participating communities. The goals of the CRS are to reduce flood damages to insurable property, strengthen and support the insurance aspects of the NFIP, and encourage a comprehensive approach to floodplain management.

Classifications and Discounts: All communities start out with a Class 10 rating (which provides no discount). There are 10 CRS classes: Class 1 requires the most credit points and gives the greatest premium discount; Class 10 identifies a community that does not apply for the CRS, or does not obtain a minimum number of credit points and receives no discount. There are 18 activities recognized as measures for eliminating exposure to floods. Credit points are assigned to each activity. The activities are organized under 4 main categories: Public Information, Mapping and Regulation, Flood Damage Reduction, and Flood Preparedness. Once a community applies to the appropriate Federal Emergency Management Agency (FEMA) region for the CRS program and its implementation is verified, FEMA sets the CRS classification based upon the credit points. This classification determines the premium discount for policyholders. Premium discounts ranging from 5% to a maximum of 45% will be applied to eligible policies written in a community as recognition of the floodplain management activities instituted.

Accuracy: The parcels and assessment records are for reference and informational purposes only and may not have been prepared for, or be suitable for legal, engineering, or surveying purposes. Users of this information should review or consult the primary data and information sources to ascertain the appropriate usage of the information. Furthermore, the county assessor’s published full-version tax maps are the primary authoritative source for surface tax maps and should be consulted if there are questions about the accuracy of the digital parcels on the WV Flood Tool. A PDF file of any full-version tax map in West Virginia can be accessed by a web browser using the following URL parameters: https://www.mapwv.gov/taxmaps/?m=02-04-037M (County Code - District No. - Map ID). Contact your county assessor office if you have questions about the parcel geometry or attributes.

Building Permits: County issued floodplain determinations and building permits are required prior to all construction, so please contact your county prior to initiating any type of development.

No Liability Provision: Tax maps are prepared for taxation purposes only and the assessor and map sales unit of the property Tax Division of the Department of Revenue shall have no liability to any third party for any errors or omissions associated therewith or in connection with the use of tax maps for any other purpose.

BUILDING DATA

Only buildings inventoried in the high-risk floodplains have a Building ID. There are an estimated 100,000 structures in the 1%-annual-chance (100-year) floodplain for West Virginia.

The Building Identifier consists of the 20-character Parcel ID plus the E-911 Address Number. Buildings which do not have an identifiable address number are annotated with ‘9999’ or other substitute value. See this link for more information about the Building Identifier.
