RE: Chase Park Apartments Stream Bank Repair
(NCDWR #19-0172; SAW-2019-00403)
Nationwide Permit #13 Reauthorization Request
Town of Chapel Hill, Orange County, North Carolina
Dear Ms. Norton and Mr. Thomas:
On behalf of our client, the Inter Church Council Housing Corporation (ICCHC), Kimley-Horn is
submitting the attached application for reauthorization under Nationwide Permit (NWP) 13 for the
Chase Park Apartments Stream Bank Repair in Orange County, NC. The existing NWP 13 (SAW-
2019-00403 was previously issued by Ms. Samantha Dailey of the US Army Corps of Engineers
(USACE) on March 9, 2019 and the associated 401 General Water Quality Certification 4134 (DWR#
19-0172) was previously issued by Ms. Karen Higgins of the NC Division of Water Resources
(NCDWR) on April 8, 2019. Due to unforeseen scheduling conflicts, construction of the project has
not started, and the project cannot be completed within the 12-month grace period following the
expiration of this permit on March 18, 2022. Additionally, a Riparian Buffer Authorization was issued
by Mr. Ernest Odei-Larbi of the Town of Chapel Hill on May 13, 2019.
This reauthorization request proposes no new stream impacts or design changes from the 2019
submittal, only recalculations of impacts to comply with the condition of the new 2021/2022
Nationwide Permit Program. However, an additional 30 square feet of buffer impacts will be
temporarily impacted in Zone 2 at Impact Site 1 as a result of the proposed grading and revegetation.
Permanent impacts to Pritchard Branch (UT to Morgan Creek) will occur as a result of the bank
stabilization. A boulder toe and a constructed riffle will be located within the channel. The stream will
be slightly realigned to allow room to lay the banks back. A total of 221 linear feet (0.04 acres) of
Pritchard Branch will be permanently impacted with no -net loss of waters.
Additionally, permanent buffer impacts will result from the grading and rip rap stabilization installation
associated with the bank stabilization. A total of 7,169 square feet of buffer zone 1 and 86 square feet

of buffer zone 2 will be permanently impacted. As stated above, a Buffer Authorization was previously
issued by the Town of Chapel Hill, the local governing body.
Temporary impacts will result to Buffer Zones 1 and 2 as a result of the grading and revegetation and
necessary construction access to the site. Equipment and material staging, and construction access
will be limited to the existing driveway and disturbed area where possible. The proposed project has
been designed and will be constructed to avoid impacts to both Pritchard Branch and the regulated
riparian buffers where possible. Necessary impacts will only occur when targeted bank stabilization
activities are underway. All temporarily impacted riparian buffer areas will be restored to pre-existing
condition upon completion of the project. Reseeding will occur within the temporarily riparian buffer
impact areas outside of location where rock stabilization has been installed.
The following information is included as part of this application:
- ePCN Application Form
- Signed Agent Authorization Form
- Figures
- Previously Issued Section 404/401 Approvals
- Previously Issued Town of Chapel Hill Buffer Authorization Approval
- Permit Impact Drawings
- Plan Set

request, please do not hesitate to contact me at [phone] or Emma. Radford@Kimley-
