There are several county-based coverages associated with this data layer.
The county names below show inundation limit file sizes for the 'fast'
hurricanes (those with forward velocities greater than 15mph). There are
coverages depicting inundation limits for the 'slow'
hurricanes (with forward velocities of less than or equal to 15mph)
as well.

Revisions and updates to this layer include:
6.) filenames: (countyabbrev)hss93s999, one metadata file.
Sept. 3, 1999: Updated one polygon coding error for surge value
in Dare County.
5.) directory: hss93_799 filenames: (countyabbrev)hss93s799
(countyabbrev)hss93f799
July 21, 1999 update includes surge updates for the following counties:
Carteret and Onslow. Detailed description of changes: Carteret
hss93s-id = 7 had surge update: '0' to '12'. Onslow
hss93s-id = 194 had surge update: '0' to '3' and hss93s-id = 110 had
surge update: '0' to '12'.
4.) directory: (coabbrev)hss93_399 filenames: (coabbrev)hss93s399
<countyabbrev>hss93f399, two compliant metadata files.
March 3, 1999 update includes addition of storm surge data for the
following counties: Beaufort, Bertie, Camden, Carteret, Chowan, Craven,
Currituck, Dare, Gates, Hertford, Hyde, Jones, Pamlico, Pasquotank,
Perquimans, Tyrrell, and Washington.
3.) directory: hss93_1298 filename: hss93f1298 and hss93s1298.
There are 2 compliant metadata files. The December
1998 update to this layer consisted of projecting the data from
NAD27 datum, State Plane projection, units of measure feet TO:
NAD83 DATUM, State Plane PROJECTION, UNITS OF MEASURE METERS.
This was done to comply with the NC Geographic Information
Coordinating Council's "Statement of Direction for North Carolina
Corporate Geographic Database Horizontal Reference, Datum and
Unit of Measure". This reprojecting was done in various ways
depending on the data type and content. Vector data was projected
using the 'project' command in ESRI's Arc software and topology
was cleaned and built based on coverage needs. Raster data was
projected using ESRI's Grid module and various steps as applicable.
2.) directory: hss93_295 filenames: hss93f295 and hss93s295
Represent the February 9, 1995 versions with 2 compliant metadata
files. The update consisted of the deletion of duplicate label
points in both coverages.
These files were previously archived under the following names
but did not have compliant metadata. filename: hss93f.295 hss93s.295
1.) directory: hss93_994 filenames: nchss93f994 nchss93s994
September, 1994 was the original release date for these coverages.
Non-compliant metadata is in the info directory.
