alGiched proposed BMP designs for each lot. The Attached basin designs will capture the

we hope that upon your review of die +uppartin~* information. yuu will agree that diffuse

On~Site Determinatian far Applicability to the 11Teuse Riparian Area Protection Rules (ISA NCAC 2B
.4233}EXPRESS REVIII!;W PROGRAM
pn July 13, 2007, at the request of Mr- Scutt Mitchell of Miteflell Environmental, P.A,, an on-site determination
was conducted to review five stream features located on the subject property for applicability to the Neuse Buffer
Rules (15A NCAC 2B .0233). The features are labeled as "A" through "E" on the attached map, initialed by h,ia
Myott on July 13, 2007. The Division of Water Quality (DWQ) has determined that the following:
• 1=cature "A" is subject to the Ner~se Bu~'er Rule on the proprrrty at the flag labeled by DWQ as "A 1 ".
Feature A is an intermittent stream.
Feature `B" is subject to the Neuse Bu„~er Rule from the tlag labclt:~d "131" to the flag labeled "$2"
(isolated stream). At the DWQ flag labeled "B3", the feature again becomes an intermittent stream and is
therefore subject to the Neuse Buffer Rule.
• Feature "C" is subject to lire Neuse Bugr Rule on the property at the flag labeled "C I ". The stream was
determined to be intermittent at "Cl".
• Feature "D" is subject to the Neuse Bu,~"er Rule on the property from the flag labeled "D6" to "DT' and
from Flag "D$" to "D9" (isolated interrrtittent streams). Downstream from flag "Dti" tht: future becomes
a wetland and ifi therefore riot subject to the Neuse t3uffer Rule,
• Feature "E" is a wetland with no stream features and is therefore not subject to the Neuse Buffer Rule.
This on-sift: determination Shall expir4• five (5) years from the date of this letter.
This letter only addtCSses the irltermitttnt/perennial status of the stream features IiStc;d above according to current
DWQ standards and does not approve any activity within the streams or address features that were not observed
during the site visit. Nor does this letter approve any activity within Wafers of the ldni[ed Sta[CS or Waters of the
State. if you have any questions, please contact Lia Myatt at 914.733.9502. /
