Dear Mr. Mumford:

Reference the Department of the Army (DA) permit issued on October 2, 2006, to
Mitch Barron of Newland Communities for impacts associated with the Briar Chapel
Development. Also reference the modifications to this permit approved in December,
2007 and August, 2009. This development is approximately 1,589 acres in size and is
located west of US Highwayl 5-50 1, north of Andrew's Store Road (SR 1528), and south
of Mann's Chapel Road (SR 1532), approximately 5 miles south of Chapel Hill, in
Chatham County, North Carolina. Coordinates (in decimal degrees) for the site are
35.8251 'North, 79.1059 ° West. The site contains several unnamed tributaries and
adjacent wetlands of Pokeberry Creek and Wilkinson Creek, in the Cape Fear River
Basin (8-Digit Cataloging Unit 03030002).
Permanent impacts authorized by this permit and the subsequent modifications
totaled 2,237 linear feet of stream channel and 0.4374 acre of wetland, and temporary
impacts totaled 634 linear feet of stream channel and 0.197 acre of wetlands. Mitigation
was implemented for the unavoidable impacts by payment into the North Carolina
Ecosystem Enhancement Program, restoration of stream channel at the Harpers
Crossroads Mitigation Site, and on-site preservation of wetlands and streams.
Also reference your permit modification request received by the Corps by emails
dated February 8, 9 and 14, 2011. This modification request involves reducing impact
amounts at the location identified within the 2009 modification as Impact U, which had a
permitted impact amount of 233 linear feet of permanent stream channel, 21 linear feet of
temporary stream channel, and 0.009-acre of permanent wetland impact. These impacts
were due to the culverted crossing of Andrews Store Road and a nearby side road. The
proposed modification would reduce these impacts by allowing Andrews Store Road to
remain as a culverted crossing but utilize a bridge on the nearby side road, therefore
-2-
reducing permanent impacts to the stream. In addition, a temporary impact is proposed to
allow for the installation of 3 utility lines. Impact U is now proposed for a total of 173 of
permanent stream channel impacts, 0.009 of permanent wetland impacts, and 31 linear
feet of temporary stream channel impacts.
The Corps has completed the evaluation of your request and concurs with your
request for a change in impacts associated with your referenced DA permit including the
change to plans as requested. The approved plans for this crossing are attached for your
file. No additional mitigation is required for this modification.
Please note that all other permit conditions and exhibits remain in effect as
written. Should you have questions, contact Mr. Monte Matthews, Raleigh Regulatory
Field Office at telephone [phone], Extension 30.
