9 1320-234 V ~ ~ ~ The site was originally assessed for wetlands and jusrisdictional waters by 'Wetland & Natural Resource rn : 3~~
r Consultants, Inc., Newton, N.C. The wetland and juridictional water areas were flagged, located by field ~',r'~°b ~yw~
i survey, and mapped for further review. Site & Utility Design Services met'' with Mr. John Thomas, US °'•,,~0 ~wy,•`•
Army Corps of Engineers, on the site on July 1, 2008. Mr. Thomas inspected the northern areas of the '•~~„~n~ ~
site for wetlands and jurisdictional waters. The Intermittent and Perennial 'Stream locations, as well as
the wetland area "1 W" were confirmed on the ground using features and flag numbers from the survey.
N 02'31'14" E Existing _ _ 87 , 109.89' ~ Mr. Thomas identified wetland area "1 W" and the temporary stream crossing "1-TS" as subject to wetland

- _ ~ r 1124-23 subject to wetland area disturbance calculations. All other stream crossings, temporary and permanent, ~ ,,r' are subject to length of disturbed perennial stream calculations according to Mr. Thomas. W J ~
