Updated 11/1/2005
Page 9 of 13
Because the two streams run entirely across the width of the property, crossings are
required to develop the site. After an on site evaluation by Lia Myott-DWQ, we have
redesigned to access road and its stream crossings to minimize the impacts.
Impact Site #1(Perennial) -The roadway was originally designed to cross the stream in the
middle of the property. We have now moved the access road closer to the eastern property
line. This was done to move closer to the intermittent/perennial point of the stream,
lessening the impact to the perennial potion of the stream. We could not avoid the
perennial portion of the stream entirely, due to its proximity to the existing property lines
(intermittent/perennial point approximately 20' east of eastern property line). We propose
to cross the stream at 90 degrees and maintain the original location of the streambed. The
stream impact to this site is 901inear feet (including pipe and rip-rap apron).
Impact # 2 (Intermittent) -This stream is not found on the Person County Soils Map or the
USGS Topo Maps. Again the roadway was originally design to cross the stream at mid-
property, now we propose to cross closer to the eastern property line to avoid the stream
impact. Due to the size rnad (30'gravel) required by the developer total avoidance was not
possible due to the property line proximity, but the eastern shift in the road allows the
designed culvert outfall to head the intermittent stream. The majority of the stream impact
will be less than half of the pipe length and the riprap apron. The stream impact to this site
is 54 linear feet (including pipe and rip-rap apron). We propose to cross the stream at 90
degrees and maintain the original location of the streambed.
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 January 15, 2002, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCEEP concurrence shall be placed on hold as incomplete.
An applicant may also choose to review the current guidelines for stream restoration in DWQ's

On-Site Stream Intermittent/Perennial Determination -EXPRESS REVIEW PROGRAM
On March 1, 2007, at the request of Brantley Wells of Summit Consulting Engineers, an on-site determination
was conducted by Lia Myott to review the stream features located on the subject property. The Division of Water
Quality (DWQ) has determined that the following:
Feature "A" is a perennial stream at the flag that is located approximately 20 feet from the eastern
property line. Caddisflies (perennial stream indicators), amphipods, and gilled salamanders were found in
the perennial stream.
Feature "B" is an intermittent stream at the flag labeled, "B 1 ". Fingernail clams, amphipods, and aquatic
worms were found in the intermittent stream.
This on-site determination shall expire five (5) years from the date of this letter.
Landowners or affected parties that dispute a determination made by the DWQ that a surface water exists and/or
that it is subject to the buffer rule may request a determination by the Director. A request for a determination by
the Director shall be referred. to the Director in writing c/o Cyndi Karoly, DWQ 401 Oversight/Express Review
