The orthophoto or other base map on which the soil lines were
compiled and digitized probably differs from the background

shifting of map unit boundaries may be evident.

Explanation: The stream(s) listed above has been located on the most recent published NRCS Soil Survey of Wake
County, North Carolina and/or the most recent copy of the USGS Topographic map at a 1:24,000 scale. Each
stream that is checked "Not Subject" has been determined to not be at least intermittent or is not present. Streams
that are checked "Subject" have been located on the property and possess characteristics that qualify it to be at least
an intermittent stream. There may be other streams located on the property that do not show up on the maps
referenced above but may be considered jurisdictional according to the US Army Corps of Engineers.
This on-site determination shall expire five (5) years from the date of this letter. Landowners or affected
parties that dispute a determination made by the DWR may request a determination by the Director. An
appeal request must be made within sixty (60) days of date of this letter. A request for a determination by the
Director shall be referred to the Director in writing. If sending via US Postal Service: c/o Karen Higgins;
