Subject: Carolina Street Extension - Riparian Buffer Authorization Request
Good morning Rob,
On behalf of our client, the Town of Morrisville, please find attached the Riparian Buffer
Authorization application for the Carolina Street Extension project in Morrisville, Wake
County, NC. The proposed project would extend Carolina Street and Foxglove Drive, and
construct a roundabout on Town Hall Drive to provide a safe and logical connection
between the extended Carolina Street and Town Hall Drive. Minor modification is

required along the southern side of Town Hall Drive and its associated fill slopes
comprising the roadway facilities in the area of the protected riparian buffer of a UT to
Crabtree Creek, but minor impacts to riparian buffers will result from the proposed
roundabout construction.
There are two impact sites as shown in the attached application: Site 1 is a
perpendicular crossing through the upper reach of a small tributary to the main UT to
Crabtree Creek. This perpendicular crossing would impact Zones 1 and 2, but the
resulting impact is less than 40 LF of along the riparian buffer which is considered
exempt in the Neuse River Basin Table of Uses. Impact Site 2 is located in Zone 2 of the
UT to Crabtree Creek, but the impact is limited to grading and revegetation in Zone 2
only, also considered "exempt" per the Table of Uses.
Due to the potentially confusing nature of these impacts, we went ahead and prepared
the Riparian Buffer Authorization form with permit drawing to help clarify the Town's
proposed impacts although both Sites should be considered "exempt" from the riparian
buffer rules. Can you review the attached documentation and confirm that no further
coordination is necessary for this project?
Thanks for your help on this project. Let me know if you have any questions or concerns,
and feel free to give me a call if you would like to discuss the project in greater detail.
Sincerely,
Jason Hartshorn, PWS
