1721 Hunting Ridge Road, City of Raleigh, NC
B. Project Information and Prior Project History
3a. Project Description
The project is located in a fully developed residential neighborhood at 1721 Hunting Ridge
Road. The watershed contributing to an unnamed tributary of the Neuse River to be repaired is
41 acres. Land use is mostly 1/4 acre lots with single family homes and a golf course.
3b. List the total estimates acreage of all existing wetlands on the property
No wetlands are located and within the limits of disturbance for this project.
3d. Explain the purpose of the project
The purpose of this project is to stabilize the stream bank along the west bank of the unnamed
tributary. This is prevent future erosion migrating towards an existing structure and provide
protection for the exposed sanitary sewer. The existing condition of the unnamed tributary is
resulting in bank erosion which is encroaching on the northeast corner of the house on the project
site. A sanitary sewer manhole exists on the outside bend, and a 4" DIP sanitary sewer lateral
crosses the stream and connects to the manhole.
3e. Describe the overall project in detail, includingthe he type of equipment to be used.
The proposed improvements (from upstream to downstream) include stabilizing the stream bank
that is eroding in close proximity to the house, providing protection for the exposed sanitary
sewer lateral crossing the stream, and stabilizing the stream around the manhole and downstream
of the manhole. Severe erosion is occurring on the bend with the near -vertical bank and will be
stabilized with a class 1 rip rap rock base and vegetated geogrid lifts. The stream bottom will be
graded to provide protection around the sewer later. Twelve (12) linear feet of constructed riffle
(class 1 mix) will hold the stream bottom around the pipe so that it does not become exposed. A
class 1 rock toe will be installed around the manhole and transitioned form the rock base under
the geogrid lifts. The rocktoe will continue for 14 LF downstream of the manhole on the west
bank. Existing class B rip rap will be utilized where appropriate. The designed stabilization
measures, rock base, rock toe, constructed riffle, vegetated geogrid lifts, and matting, exceed the
resistance required to protect the bank from the anticipated shear stress.
The equipment to be used in the project is earth moving equipment and various other support
apparatuses. Heavy equipment may include hydraulic excavator, compactors, bulldozers,
skidsteer loaders, and dump trucks to load and unload materials. The construction equipment will
enter the site from Hunting Ridge Road along an existing sanitary sewer easement and will
perform all construction within a defined limit of disturbance. All work will be completed from
the west bank of the stream. The stream will not be crossed as a part of this project.
C. Proposed Impacts Inventory
6i. Comments:
B1: Stream stabilization with occur along the west bank. The area will be re -graded, matted, and
re -vegetated.
B2: Construction equipment will enter from Hunting Ridge Road. Area will be re -vegetated. The
area that has been slated for dispersement of existing soil will be in an existing lawn area. This
area will be reseeded to model existing grass.
D. Impact Justification and Mitigation
la. Specifically describe measures taken of avoid or minimize the proposed impacts in designing
project.
This project is necessary to stabilize the stream channel and to eliminate active erosion of the
stream channel bank. The minimization of the project has limited the repairs to the areas of the
stream banks that are currently severely eroding. The buffer impacts will minimize impacts to
existing vegetation by accessing the site along an existing sanitary sewer easement.
lb. Specifically describe measures taken to avoid or minimize the proposed impacts through
construction techniques.
The proposed construction will minimize proposed impacts by performing all construction from
the top of the western stream bank. The proposed structural measures include rock for stability at
the stream toe along with the exposed sanitary sewer cleanout and vegetation to re-establish root
systems on the stream bank for long term stabilization.
F. Supplementary Information
5d. What data sources did you use to determine whether your site would impact Endangered
Species or Designated Critical Habitat?
The site is an existing urban residential area that has been previously impacted by development.
Habitat is not present for Wake County listed vertebrate and invertebrate endangered species
with the exception of Northern Long Eared Bats. Michaux's sumac prefers open areas and is
relatively shade tolerant. The site is forested with other open areas currently being mowed. The
project requires removal of a few bushes for access. No trees are planned to be removed as a part
of this project. Therefore it is not anticipated that there will be any adverse impacts associated
with TAE species.
