Permanent impacts to S01 will occur in three separate areas (See attached Plan Sheet) and total to 122.5 linear feet. Impacts to S01 will be covered
under NWP 18
Permanent impacts to S02 will be covered under the NWP 27 for stream enhancement - the channel is being redesigned to accommodate stormwater
flows and an accessible floodplain bench is part of the redesign. Therefore although the impacts are permanent, there will be no 'loss of WOTUS"

Impact Justification and Mitigation
1.
Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
The owner's representative was granted approval by the City of Asheville to utilize City of Asheville Low Impact Road Standards which allows for a
smaller ROW and reduces the road width requirements. Both of which helps keep the homes closer to the road and prevents impacts to the stream
and wetland areas on-site. The layout avoids impacts to the stream and wetlands at the southern end of the property entirely. The impacts to the
wetland in the center of the property has been minimized as a loop road utilizes two existing culvert locations to cross the stream.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Work on streams will occur in the dry using a pump -around system for the duration of the in -channel work. Construction equipment will kept out of
stream channels and wetland areas. Areas of soil disturbance will be properly stabilized with matting or seeding or both, and WOTUS will be protected
from siltation using silt fencing. All WOTUS upstream of the stormwater wetland complex will remain undisturbed.

❑X Yes ❑ No
2c.
If this project DOES NOT require a Stormwater Management Plan, explain why:
2d.
If this project DOES require a Stormwater Management Plan, then provide a brief, narrative
description of the plan:
In the
proposed scheme, the pond will be demolished and the existing dam will be removed. In its place will
be built a constructed wetland that allows
creek base flows and bed sediments to flow freely through a low-flow channel. During storm events, the wetland control structure will regulate outflows
so that excess runoff will accumulate in the wetland, and upstream into the undisturbed reach. The water surface
of the wetland will stage up to create
temporary shallow ponding in a floodplain wetland. Downstream of the constructed wetland, the creek channel will be re-shaped to a more stable form,
and native riparian vegetation will be planted to promote bank stability. At the edge of the riparian buffer, shallow linear depressions will be created to
capture any sheet flow or concentrated runoff before it reaches the creek. Depressions will function as floodplain wetlands and promote infiltration.
