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 Project is found on the City of Asheville, Bee Tree Lake property, a large forested property and water source for
the City. The Project Site is located below the Bee Tree Lake dam (and water intake) and includes a 50-If section of
unstable streambank on an unnamed tributary (UT-1) to Beetree Creek. A section of slope has sloughed into UT-1
resulting in 1-2 vertical feet of surface soil loss which destabilized the streambank with the loss of several large trees.
UT-1 is partially obstructed by fallen trees and sediment (see Photo Sheet).
An existing waterline is located on the upstream end of the slope failure. No wetlands were delineated within the
Project Site. The Project Site is within FEMA mapped 100-year floodplain (AE). Properties in the surrounding area
consist primarily of rural residential land use. Beetree Creek changes from WS-1 / HQW stream classification above
the dam to class 'C' waters below the dam.
3b. List the total estimated acreage of all existing wetlands on the property:
There are no wetlands on the Project Site.
3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property:
UT-1 Beetree Creek: 100-If (within the Proiect Site)
3d. Explain the purpose of the proposed project:
The purpose of the project is to stabilize a severely eroded streambank, including the slope above, and protect the
existing water line upstream of the slope failure.
3e. Describe the overall project in detail, including the type of equipment to be used:
The Project will involve using gabion baskets, up to 50-If, to stabilize the left side of UT-1 in the area of the slope
failure. Gabion basket design will be installed according to attached plans to a height of 9-feet with a 2:1 slope above.
The proposed gabion basket design will abut the existing stream channel and tie into stable sections of streambank
and slope on upstream and downstream ends. The proposed fill slope above the gabion baskets will be stabilized with
staked woven coir mat, erosion control seed mix and overseeded with native riparian seed mix (ERNST-304) from
Ernst Conservation Seeds or similar. Permanent stream impacts will occur as a result of the streambank stabilization:
S-2, totaling 50-If (see Plan Sheet).
In addition to installing a gabion basket structural streambank, the Project will remove fallen trees and sediment from
the UT-1 stream channel. Work will be completed from the streambank, to the maximum extent practical, in order to
minimize equipment in the channel. A timber mat may be utilized to get equipment across the stream channel, if
necessary. Access to the Project Site can be gained from the right side of the stream channel from an adiacent
existing gravel road or, from the top of the bank on the left side of the stream channel. Dewatering techniques will be
employed to ensure work is completed in the dry resulting in temporary stream impacts (refer to Dewatering Typical):
S-1, totaling 10-If (see Plan Sheet).
Erosion measures will be utilized around areas of work to prevent sediment runoff into the stream channel. Excavated
soils will be stockpiled in areas away from the stream channel, surrounded by silt fence. Disturbed areas of the
streambank will be stabilized with temporary erosion control seed mix and over seeded with native riparian seed mix
(ERNST-304) from Ernst Conservation Seeds or similar. If a loss of woody vegetation occurs during work, live stakes
will be planted to ensure long term bank stabilization and restoration of riparian habitat.
Trackhoe and dump trucks will be used for site work.

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
The purpose of the Project is to stabilize a severely eroded streambank that is contributing sediment to the stream.
This proiect will achieve this purpose with minimal permanent impacts.
b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Disturbed areas along the streambanks will be stabilized immediately following construction activity. Equipment will be
kept out of the stream to the maximum extent practical by utilizing timber mats for crossing and working from the
streambanks. Erosion control measures will be employed to prevent sediment runoff. Dewatering technique will be
used to enable to working in the dry. Excavated soils will be stockpiled away from jurisdictional waters and will be
surrounded by silt fence.
