Re: Riparian Buffer Authorization, Cary- Raleigh Water Supply Interconnections Project —
Phase I, Town of Cary, Wake County, North Carolina
Dear Ms. Higgins,
Please find attached the Pre - Construction Notification (PCN) Application for Riparian Buffer
Authorization for the above referenced project. The Town of Cary is installing intraconnections
and interconnections between two Town of Cary water mains. The connections are being
installed to strengthen water availability to Wake County, Cary, Raleigh, and Holly Spring
municipal water users.
Land disturbance associated with the intraconnections and interconnections is minimal.One of
the connection sites, the Birkhaven Site, which is depicted on Sheet C -02 of the attached plans,
is located adjacent to a blue line intermittent stream, an unnamed tributary (UT) to Swift Creek.
The location of the existing water mains relative to the UT to Swift Creek requires project work
to be performed within Zone 1 and Zone 2 of the riparian buffer. At present, the existing
easement contains woody vegetation that will be removed during construction. As required by
the North Carolina Department of Environment and Natural Resources, the post- construction
easement over the pipe will be maintained as a mowed, herbaceous community to allow for
future access to the water main.
If you have any questions or require additional information, please contact me at 919.863.9256.
Thank you for your assistance.
Sincerely,
HAZEN AND SAWYER, P.C.
