Description:

Abstract:

This GIS data set encompasses floodway and floodway fringe data for Henderson County, NC. It contains Reference Mark information. This data was digitized from 1982 Federal Emergency Management Agency (FEMA) Flood Insurance Rate Maps (FIRMs) as the mandated source of this information.

Purpose:

This data set was created to help the Henderson County Planning Department better serve County residents by making this data available via a GIS data set.

Supplemental_Information:

This GIS data set was created to delineate the floodway fringe and floodway information within this jurisdiction. Users of this map are hereby notified that public primary information sources should be consulted for variation of the information contained in this data. The County assumes no legal responsibility for the informaiton contained in this data. The hardcopy FIRMs are still considered the legal map and official source of this information.

Use_Constraints:

Must read and fully comprehend the metadata prior to data use. When using this data set as a source you must fully recognize the Henderson County Planning Department as the Originator of this data. Henderson County shall not be held liable for any errors in this data. This includes errors of omission, commission, errors concerning the content of the data, and relative and positional accuracy of the data. This data cannot be constructed to be a legal document. This data is NOT a survey document and should NOT be utilized as such. Primary sources from which this data was compiled must be consulted for verification of information contained in this data. This data may NOT be resold. The hardcopy FIRM and the accompanying FIS are the official designation of SFHAs and Base Flood Elevations (BFEs) for the NFIP. For the purposes of the NFIP changes to the flood risk information published by FEMA may only be performed by FEMA and through the mechanisms established in the NFIP regulations (44 CFR Parts 59-78). The hardcopy flood maps and flood profiles are the authoritative documents for the NFIP.

Attribute_Accuracy:

Attribute_Accuracy_Report:

The GIS data set represented contains the attribute values as shown on the map. Please refer to FEMA for their methodology for creating the hardcopy FIRMs to determine what field methods, cross-checks and other analysis that went into creating the different flood data values.

Logical_Consistency_Report:

These data were created via on-screen digitization utilizing scanned flood maps obtained from FEMA. All care was used to ensure accuracy. Hardcopy FIRMs were used to double-check the scanned images. Two different people QC'ed the information on the consultant side and another higher level QC was done on the Henderson County side to ensure accuracy.

Completeness_Report:

This data set is complete. Due to the inconsistency of the scanned documents, some generalizations were made along map boundaries where the referenced images did not line up perfectly. The cross-sections from the Floodway maps are not included in this dataset at this time.

All information in this GIS data set was pulled off this digital scanned image of the FIRMs and verified with the hardcopy paper FIRMs.

Process_Step:

Process_Description:

1) Scanned flood plain maps were purchased from http:\\www.FEMA.gov. 2) Scanned maps were registered / rectified using (a) stream data acquired from the NC CGIA and (b) street centerline data acquired from Henderson County. This was done using the 'Georeferencing' toolbar in ArcMap 9.0. CGIA Stream data were acquired at 1:24,000. 3) Flood plain boundaries were digitized into a line shapefile. Snapping was used to ensure clean data at the time of capture. 4) Once the digitizing was completed, said shapefile was put into a personal geodatabase. 5) Within the geodatabase, a blank polygon feature class was created as well as a topology class. 6) Next, the digitized lines were converted into polygons utilizing topology. 7) A text field ("CODE") was created and polygons coded according to the values found on the scanned flood maps. 8) Flood way data, previously created for Henderson County, was appended to the newly created flood plain data. Some manipulation of the flood way data was done to ensure that flood ways fell inside of flood plain polygons. This was done 'heads-up', using county orthophotos and CGIS stream data for reference. 9) Geoprocessing tools were used to buffer all flood plain features (Zone A) by 250 feet. That new zone was then coded accordingly. 10) A new field and subtype based on that field were created encompassing all possible values. 11) An intersection procedure was done to capture the flood map references into the attribute table. 12) Metadata was created.
