RE: Nationwide Permit 18, 39, 401 Certification, Isolated Wetlands Permit
Ravenstone Subdivision MAR 8 2004
Durham, Durham County, North Carolina
(Latitude/Longitude:) 35° 58' 17.81" N, 78° 47'32.03" W MATER QUAL! 1Y SECTION
Dear Mr. Domey and Mr. Tugwell:
On behalf of Sherron Road Ventures LLC, we hereby request authorization from the US Army
Corps of Engineers (USACE) to use Nationwide Permits 18 and 39, and from the NC-Division of
Water Quality (DWQ) request Isolated Permits, 401 Certification, and Buffer Compliance for the
subject project to cover permanent impacts to jurisdictional stream channels (unnamed tributaries
of Lick Creek), wetlands, and isolated channels. A Pre-construction Notification Application
(PCN) is attached, as well as an agent authorization form.
The applicant requested that S&EC delineate the wetlands, stream channels, and buffers on the
entire property prior to designing the subdivision in order to minimize impacts. A copy of the
applicable USGS Quadrangle and Soil Survey are attached showing the property. Buffer
confirmation from the NC-DWQ was issued on January 29, 2003. A site meeting with the
USACE was performed on January 10, 2003. We have enclosed the jurisdictional determination
from this meeting.
The proposed project consists of the construction of a residential subdivision to serve the
surrounding community. Impacts include 230 linear feet of jurisdictional channel as part of
improvements to the existing roadways (i.e. installing curb and gutter and culvert extension),
8,254 ft2 of wetland impacts due to road crossings and 22,324 ft2 of zone 1 buffer impacts, 9,603
ft2 of zone 2 buffer impacts due to road crossings. In addition, the construction of an extended
detention wetland will impact 10,222 ft2 of Zone 2 of the riparian buffer. Isolated channel
impacts include 65 linear feet of channel. The proposed impacts are elaborated upon in the
attached PCN form and impact maps. A meeting was held with Mr. John Dorney of the NC-
DWQ on February 12`t', 2004 at which time he verbally approved the use of the proposed
extended stormwater wetlands. A separate meeting was held with Mr. Todd Tugwell of the

Previous history includes the permit for the sanitary sewer outfall, force main for the Ravenstone
Development (DWQ Project # 03-0769). In September 2002 a detailed wetland delineation was
conducted by S&EC at the request of the client in order to minimize impacts to streams and
wetlands to the maximum extent practicable. Buffer confirmation from NC-DWQ was issued on
January 29, 2003 A site meeting with the USACE was performed on January 10, 2003. We
have enclosed the jurisdictional determination from this meeting. A meeting was held with Mr.
John Domey of the NC-DWQ on February 12th 2004 at which time he verbally approved the use
of the proposed extended stormwater wetlands. A separate meeting was held with Mr. Todd
Tugwell of the USACE on the same day at which time he also verbally approved the extended
stormwater wetlands.
V. Future Project Plans
Are any future permit requests anticipated for this project? If so, describe the anticipated work,
and provide justification for the exclusion of this work from the current application.
No future impacts are anticipated
VI. Proposed Impacts to Waters of the United States/Waters of the State
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
wetlands, open water, and stream channels associated with the project. The applicant must also
provide justification for these impacts in Section VII below. All proposed impacts, permanent
and temporary, must be listed herein, and must be clearly identifiable on an accompanying site
plan. All wetlands and waters, and all streams (intermittent and perennial) must be shown on a

VII. Impact Justification (Avoidance and Minimization)
Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss. construction
techniques to be followed during construction to reduce impacts.
In September 2002, a detailed wetland delineation was conducted by S&EC at the request of
the client in order to minimize impacts to streams and wetlands. In order to minimize stream
impacts all stream crossings for the proposed subdivision are located at existing crossings that
need to be uvgraded in order to install curb and Utter. The remaining streams/wetlands and
buffers will be preserved
VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on March 9, 2000, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors

Dear Ms. Gadd:
I have reviewed the maps that you have submitted for the project referenced by the Raleigh Regional Office
as NBRRO-03-025. An evaluation of the stream features was performed on December 17, 2002 to determine
whether the site would require compliance with the Neuse Buffer Rule.
The features represented on the Durham County Soils and the Southeast Durham USGS topographic
maps were evaluated to determine their subjectivity to the Neuse Buffer Rule. It was determined that
there are nine features represented on the property between the two maps. These are labeled as Features A
through I as indicated on the attached plat map.
Features G, and H are not subject to protection under the Neuse River Basin-Nutrient Sensitive Waters
Management Strategy: Protection and Maintenance of Existing Riparian Areas, Administrative Code
T15A:02B.0233 (NCAC 0233). A small portion of Feature F (broken subjectivity) and the area of Feature
I that encroaches into the property are subject. The remaining features are subject through the property.
This letter addresses only those issues involving the riparian area. For information relative to the Wetlands
401/404 issues, please contact Mr. John Dorney at 919-733-1786. Thank you for your attention to this matter
and if this Office can be of any assistance or if you have additional questions, please do not hesitate to
contact me at 571- 4700.
Sincerely,
Steve Mitchell

Size and Location of Property (waterbody, Highway name/number, town, etc.): The 66 acre property
is located adjacent to the NC 98/Sherron Road (SR 1811) intersection, south of NC98, southeast of
Durham, Durham County, North Carolina.
Basis for Determination: The site contains wetlands and stream channels with indicators of ordinary
high water marks, located adjacent to an unnamed tributary of Lick Creek in the Neuse River Basin.
Indicate Which of the Following Apply:
There are waters of the U.S., to include wetlands, on the above described property which we strongly suggest
should be delineated and surveyed. The surveyed wetland lines must be verified by our staff before the Corps will
make a final jurisdictional determination on your property.
Because of the size of your property and our present workload, our identification and delineation of your wetlands
cannot be accomplished in a timely manner. You may wish to obtain a consultant to obtain a more timely
delineation of the wetlands. Once the consultant has flagged a wetland line on the property, Corps staff will
review it, and, if it is accurate, we strongly recommend that you have the line surveyed for final approval by the
Corps. The Corps will not make a final jurisdictional determination on your property without an approved survey.
X The waters of the U.S., to include wetlands, on your lot have been delineated, and the limits of the Corps
jurisdiction have been explained to you. Unless there is a change in the law or our published regulations, this
determination may be relied upon for a period not to exceed five years from the date of this notification.
There are no waters of the U.S., to include wetlands, present on the above described property which are subject to
the permit requirements of Section 404 of the Clean Water Act (33 USC 1344). Unless there is a change in the law
or our published regulations, this determination may be relied upon for a period not to exceed five years from the
date of this notification.
Placement of dredged or fill material in wetlands on this property without a Department of the
Army Permit is in most cases a violation of Section 301 of the Clean Water Act (33 USC 1311). A
permit is not required for work on the property restricted entirely to existing high ground. If you
have any questions regarding the Corps of Engineers regulatory program, please contact
Andrea Wade at telephone number (919) 876 - 8441 extension 31
