Dear Ms. Higgins,
On behalf of WBTH LLC., we are requesting Buffer Compliance from the NC-DWR for 630 sq ft of
permanent Neuse River buffer impacts for construction of a rip rap bypass stormwater outfall
within the West Brier Townes SCM #2 Outfall project.
The project area is located within the West Brier Townes residential subdivision, southeast of the
intersection of TW Alexander Drive and Roche Drive in Durham (35.915226°N; -78.823529°W).
The project is located in the Neuse River basin and onsite waters drain to Stirrup Iron Creek. The
Water Quality Classification for Stirrup Iron Creek is C; NSW and the Stream Index Number is: 27-
33-4-2. The cataloging unit for the site is 03020201.
Proposed Project
The proposed project consists of the construction of a high flow bypass for SCM #2 within the West
Brier Townes residential subdivision. The proposed outfall consists of a storm drainage pipe which
will outfall into a rip -rap lined channel. The proposed stormwater outfall will convey treated
stormwater from a wet detention pond (SCM #2), which will provide 90% nitrogen removal and
therefore diffuse flow is not required.
Project History
North Carolina Division of Water Resources (NCDWR) issued a Buffer Determination (NBRRO02-
132 & 00-015) for the project area on 06/26/2002. A copy of the Buffer Determination has been
provided as an Appendix.

Our People. Your Success.
The US Army Corps of Engineers (USACE) issued an Approved Jurisdictional Determination (AID:
SAW -2007-01242) for the project area on 01/29/2009. A copy of the Jurisdictional Determination
has been provided as an Appendix.
The West Brier Townes residential subdivision is part of the larger Alexander Park project. The
Alexander Park project received previous 404, 401 and Buffer Authorizations for construction of
two road crossings (Roche Drive and Bateau Way) and installation of utility lines which required
0.05 acres of permanent wetland impacts, 113 If of permanent stream impacts, and 12,808 sf of
permanent riparian buffer impacts. All infrastructure needed for the West BrierTownes residential
subdivision were permitted as part of Alexander Park. The permits for Alexander Park consist of:
• NCDWR issued a 401 Water Quality Certification (DWR# 14-0048) for the Alexander Park
project on 02/11/2014. A copy of the 401 Water Quality Certification has been provided as
an appendix.
USACE authorized use of NWP 12 and NWP 14 for the Alexander Industrial park project
(AID#: SAW -2014-00239) on 02/07/2014. A copy of the 404 has been provided as an
appendix.
Proposed Impacts
The proposed impacts for this application consist of 630 sq ft of permanent impacts to riparian
buffers (zonel: 132 sq ft; zone2: 498 sq ft for the construction of a high flow bypass channel for a
wet detention pond (SCM #2).
Avoidance and Minimization
The proposed high flow bypass channel has been designed to cross riparian buffers at a
perpendicular angle to minimize impacts to buffers.
The proposed project will be constructed in accordance with requirements of the erosion and
sediment control plan/permit. During construction, all equipment will access construction areas
from high ground.
Mitigation
The proposed buffer impacts are considered "Allowable" based on the Neuse River Basin table of
uses; therefore, mitigation is not required.
The current request is for 630 sq ft of permanent impacts to Neuse River basin riparian buffers
(see the attached maps and PCN for details).

Dear
Originally this site was evaluated as NBR 00 -tat S and all four features were determined to be subject
to the Nouse River Basin: Nutrient Sensitive Waters Management Strategy; Protection and Maintenance
of Existing Riparian Areas, Administrative Code Ti 5A.02B.0233 (NCAC 0233). This site was revisited
on May 21, 2002 to aflow a determination to be made as to whether or one of the unnamed tributaries
would require complienca with the Neuse Buffer Ruls, This specHic project is referenced by the Raleigh
Regional Office as NBRRQ 02.132.
The main creek and unnamed tributaries 2 and 3 remain subject to the fifty (501 foot protection but
feature 4 was reevaluated and classified as not present on the ground as a stream. This letter
addresses only the applicability of the Neuse Buffer Rules. For information relative to the buffer and
wetlands impacts or 4011404 issues, please contact Mr. John Dorney at 819-733-17811, 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 us.
