Dear Mr. Haertling:
As authorized, Mr. Benjamin V. Wilson, P.E. of ATC visited the site 2 times in September and
October 2019 and on March 2, 2020 observed the entire site and the low lying areas shown on
the attached maps.
The current phase of the property consists of one parcel totaling 24.17 acres. The entire property
consists of 99.82 Acres.
Maps of the properties are included in the appendix and photos are included with the wetlands
and stream assessment forms in the Appendix.
A determination was made of the streams and wetlands in accordance with the following methods:
Wetlands for 404 Permitting - A determination was made of the wetlands based on the
Corps of Engineers (COE) 1987 Wetlands Manual using the routine method and the
Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Eastern
Mountains and Piedmont Region (Version 2.0) April 2012 which is the currently accepted
methodology.
Streams for 404 Permitting by the (COE) - A preliminary determination was made of the
streams based on our experience with the most recent methodology used by the US Army
Corp of Engineers.
Streams for 401 Permitting and Determination of Stream Buffers by the NCDENR
Division of Water Quality - A determination was made of the streams using the North
Carolina Division of Water Quality (NCDWQ) stream determination form method. The site
is located in the Brier Creek watershed in the Haw River/Jordan Lake Basin.

The site is located on an unnamed tributary to Beaverdam Creek in the Neuse River Basin. The
site is shown as having three (3) stream locations (Features A and B and C) on the Wake County
Soil Survey and two on the USGS map (see attached maps). The wetlands and streams at the
site were delineated in 2007 and approved and a Nationwide Permit was issued in 2008. The
2007 Delineation is attached.
The 2007 Maps showing the features with 2020 notes are attached.
A summary of features at the site is included in the tables below:

ATC Project # 45.27923.0007
Dear Mr. Goodrich:
As authorized, Mr. Benjamin V. Wilson, P.E. of ATC Associates visited the site
observed the site and the low lying areas. A preliminary determination was made of the
wetlands in accordance with the Corps of Engineers (COE) 1986 method. A preliminary
determination was made of the streams using the North Carolina Division of Water
Quality (NCDWQ) stream determination form method.
The site is located in the Beaverdam Creek watershed in the Neuse River Basin and is
subject to North Carolina’s Neuse River stream buffer rules which require a 50 feet
buffer on both sides of the streams.
The site is shown as having streams on both the Wake County Soil Survey and the
USGS map (see attached maps).
Based on the site investigation there are two streams on the site located below the dam
locations of the previous ponds which have been drained and some wetlands areas on
site primarily adjacent to the stream locations and in some areas the only wetland areas
will be the stream bank to bank. See Attached maps for illustration.
Based on preliminary conversations with you we anticipate the design for the site will have
wetlands impacts of less than 1/2 acre and less than 150 linear feet of stream impact at the
property. Maps with approximate locations of the wetlands and streams based on the
preliminary site walkover for the proposed project are enclosed with this letter.

Because the acreage of impact to wetlands will likely be less than 1/2 acre and stream
impacts will be less than 150 feet the project would require preconstruction notification
under NWP 39.
Because the USGS map and the Wake County Soil Survey maps show streams on the site
a field visit will be required by both the NCDENR and USACOE. Prior to the site visits an
agent authorization form will be required. If you desire to proceed I will schedule a site visit
by the appropriate personnel. The agent authorization form should be signed and faxed to
me to be turned in with the site layout at the appropriate time.
Please contact Ben Wilson at (919) 871-0999 or (919) 697-5446 if you have any
questions or if we can be of further service.
