Habitat Conservation Program
DATE. July 13, 1997
SuBjF.cT: Prc-Construction Notification Application for Nationwide Permit for City of
Edon, Rockingham County, North Carolina DWQ 97-0509
Biologists with the North Carolina Wildlife Resources Commission have reviewed the
subject document. Our comments are provided in accordance with provisions of the Clean Water
Act of 1977 (33 U.S.C. 466 et seq.)
The applicant proposes to construct a dry detention pond on an unnamed tributary to Lary
Creek. The purpose of the dry detention pond is to serve as a watershed control structure to
protect downstream areas from flooding. Construction of the pond will include placement of a
dam across the creek channel and flooding 475-feet of the unnamed tributary.
We prefer that stormwater ponds not be constructed irtstream but be placed in adjacent
upland areas off the tributary. If a permit is issued for this structure, we would prefer that it be
designed as a wet detention pond so that in addition to reducing flooding that pond could provide
greater water duality functions. With proper design some wetland areas possibly could be
created within the basin.
Thank you for the opportunity to review and comment on this project. If we can provide
additional assistance, please contact me at [phone] or Shari Bryant at [phone].

Dear Mr. Dorney:
91991
c?1;+ -0,IXENTA!SCIENCES
The City of Eden, North Carolina has submitted a Nationwide 26 permit application to Mr. John
Thomas of the US Army Corps of Engineers in Raleigh, North Carolina to construct a dry detention
basin on approximately 475 linear feet of an unnamed tributary to Dry Creek in the City of Eden, NC.
The purpose of the proposed project is to provide flood protection to the residents of the Dry Creek
watershed. The flooding problems within this watershed are severe, causing substantial property
damage on an annual basis and causing public safety problems due to roadway overtopping at culverts
and flood waters in and around houses. The City commisioned Woolpert, LLP of Charlotte, North
Carolina to perform hydrologic and hydraulic modelling of the watershed and recommend alternative
solutions. Based on the findings of the study, and an extensive public involvement program, The City
elected to proceed with the design of the proposed detention basin.
The following items have been enclosed:
• Vicinity map to the project site (USGS Quadrangle Northeast Eden, 1 "=2000')
• Sketch of the proposed detention basin, including limits of clearing and preliminary grading
plan.
• Summary of design specifics and flood reduction benfits provided by the detention basin
• Information concerning National Wetlands Inventory research results (overlay to quad map)
Seven copies of the Joint Application Form and attached materials are hereby submitted to obtain
written concurrence regarding the Section 401 Water Quality Certification. We greatly appreciate your
,? . review of the enclosed materials and the expeditious processing of this request. If you have any
questions concerning the application, please do not hesitate to call either myself at [phone] or
Michael Brennan at Woolpert, LLP at [phone].
Sincerely,
teve ?Branz, PE

Re: Dry Creek Watershed Flood Protection
City of Eden, NC
Nationwide 26 Permit Application
Dear Mr. Cole:
The City of Eden, North Carolina has contracted Woolpert, LLP to design flood protection
measures in the Dry Creek Watershed, USGS quadrangle map "Northeast Eden" (see enclosed
vicinity map). The project includes the construction of a dry detention basin on approximately 475
linear feet of an un-named tributary of Dry Creek in Eden, North Carolina. The proposed location
is south of Fieldcrest Road and east of New Street
As part of the application for the Nationwide 26 permit, we are required to notify your agency
regarding the presence of historic properties in the permit area that may be affected by the
