RE: Nationwide Permit 14 Application
West Chatham Street — Connecting Cary Sidewalks (SAW-2023-00461)
Cary, Wake County, North Carolina
Dear Ms. Capito and Mr. Ridings:
On behalf of our client, the Town of Cary, Kimley-Horn is submitting the attached application for
authorization under Nationwide Permit (NWP) 14 for the above -referenced project in Wake County.
The Town of Cary is proposing the construction of seven sidewalk projects as part of the Cary
Community Plan which highlights the importance of a multi -modal transportation system to provide a
safe and accessible transportation network for all users. The West Chatham Street project is one of the
seven sidewalk projects and will construct a sidewalk to fill in gaps along the eastern side of West
Chatham Street in Cary, Wake County, NC. The project study area is an assemblage of NCDOT rights -
of -way and portions of five parcels along West Chatham Street (Connecting Cary "Project G").
Kimley-Horn staff conducted a delineation on January 10, 2023, and identified one stream (S1) and
one wetland (W1) within the project study area. A Preliminary -Jurisdictional Determination Request
(SAW-2023-00461) was submitted to Mr. Lyle Phillips of the USACE on February 20, 2023, and
documentation is pending. Additionally, Mr. Rob Ridings of the NCDWR issued a Buffer Determination
Letter for the project on February 21, 2023.
Unavoidable permanent impacts to streams and the associated Neuse River Basin Buffer Zones will
result from the proposed sidewalk alignment. Permanent (21 LF; 0.0015 acres) and permanent no -net
loss (14 LF; 0.0014 acres) stream impacts to stream S1 are proposed at the Connecting Cary Project
G Stream Impact Site 2 (referenced as Site 2 on attached Permit Drawings and Impact Summary
Tables) as a result of the proposed culvert extension and associated rip -rap placed around the culvert
outlet. A total of 5 LF (0.0005 acres) of temporary impacts to stream S1 will result from the construction
access necessary to install the proposed culvert and associated rip -rap. All temporarily impacted
streams will be returned to pre-existing conditions upon completion of construction. Due to the minimal
permanent stream impacts (<0.02 acre) resulting from the proposed project, compensatory stream
mitigation has not been proposed

Additionally, at Connecting Cary Project G Buffer Impact Site 2, a total of 1,966 square feet of
unavoidable permanent impacts to buffer zone 1 and 1,406 square feet of permanent impacts to buffer
zone 2 of stream S1 will result from the proposed construction of the sidewalk path and shoulder.
Additionally, a total of 439 square feet of temporary impacts to buffer zone 1 and 248 square feet of
temporary impacts to buffer zone 2 will result from the construction access necessary to install the
proposed culvert and associated rip -rap, as well as construction of the sidewalk.
According to NCDWR's Neuse River Basin's Table of Uses, the buffer impacts resulting from sidewalks
that are "equal to or less than 10 feet wide with two -foot wide shoulders... and located outside Zone 1
unless there is no practical alternative" are considered "allowable upon authorization". Therefore, no
compensatory buffer mitigation is proposed as part of this application.
