3. Project Description
3a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this
application:
The site usage is a community park. The general land use in the vicinity of the property is developed urban
residential.
3b. List the total estimated acreage of all existing wetlands on the property:
0
3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property:
800
3d. Explain the purpose of the proposed project:
Restoration of an UT to Shelton Branch to aid in the stabilization of stream banks, stream channel, and provide
improvement/enhancement of the overall aquatic habitat.
3e. Describe the overall project in detail, including the type of equipment to be used:
Six log sills will be placed in the stream and embedded in the bank to maintain flow in the center of the stream
channel and reduce stream bank erosion risk. Several trees and /or shrubs will be planted to further protect the
stream bank and filter stormwater.
The existing stream channel has two sharp meanders that are increasing the risk of stream bank erosion. To
reduce the angle at each meander, approximately 30 ft long x 2 to 3 i t wide portion of stream bank will be moved
from one side of the stream bank to the other (60 ft total will be moved) . The newly formed channel will be
consistent with the remaining stream reach, as well as create a bench to dissipate stormwater energy when it
overflows the main channel. A log sill will be placed at the downstream end of each section.
A backhoe will be used for installation and placement. Fine excavation and grading will be conducted by hand
digging. Standard controls (i.e., silt fence, native grass seeding, coir matting) will be used to prevent erosion and
sedimentation.

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1 a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Conceptual design plans were created through Haywood Community College's Low Impact Development
program. The final engineering specifics will be created by Zink Environmental in collaboration with Town of
Waynesville staff. Jason Zink is an engineer previously employed with NC State University's Water Quality Group
and has extensive experience_ designing and implementing water quality improvement and low impact _
development projects. In- stream impacts and impacts to riparian buffers will be minimized to the extent feasible.
Considerations will be made for stream slope, erosion prevention and sediment control.
b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
The amount of digging in the stream channel will be only the amount necessary for installation of the log sills
and movement of stream banktyty. Fine excavation and grading will be conducted by hand digging. Standard
erosion and sedimentation controls (i.e., silt fence) will be used to prevent erosion during installation. Impacted
riparian buffer area will be seeded in native grasses and covered in coir matting at project completion. Additional
protection will be made through planting of riparian shrubs and trees in select locations.
