ENV is submitting an addendum to a previously submitted PCN application referenced ced 034 Ci
above,
dated March 30, 2009. This PCN application has been assigned the project number 0,9-Or46. This
addendum addresses access to lot #38, which has been platted. Access to this lot is proposed to
cross a narrow, linear seep below its source from an existing, paved cul-de-sac. A driveway is
proposed to be constructed incurring approximately 0.009-acre impact to wetland unit W-19. This
wetland impact number is W4 and is shown on the revised impact table. Driveway access will
add fill and a 40' x 18" CMP for road construction. Fill is proposed to be composed of surge
stone and filter fabric in order to help maintain subsurface flow from the wetland source to
portions of the wetland below the impact site. The CMP is provided for additional flow and
stormwater drainage.
If you have any questions regarding this information, please call the ENV office at (828) 297-
6946.
Sincerely,

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
All phase I site development has been designed to completely avoid 404/401 impacts. Phase II road construction has incurred
temporary fill impacts to streams which will be negated through a restoration plan established with the USACE. A total of 110
linear feet of stream channel will be restored on tributary UT-Miller Branch 2E below the road crossing by installing grade
control structures, shaping the banks, pulling fill from the channel, and planting disturbed portions of the riparian buffer. A total
of 10 linear feet of fill will be removed in the stream channel of UT-Miller Branch 2B below the road crossing. Project site
imperviousness has been reduced by aligning Bear Paw Road along the northern property boundary using an existing timber
road grade. This alignment allows using driveways to access lots reducing potential runoff and erosion from excessive road
gradients. In addition, 71-acres of the subject property will be permanently protected acting as preserves which include
vegetated buffer zones to stream corridors.
Proposed wetland impact site W4 has been minimized by subdivision road layout. This layout calls for a driveway crossing
rather than a subdivision road to provide access to lot #38, which reduces proposed impacts. This proposed wetland crossing
is located in a portion of the site which is relativey flat allowing for decreased fill amounts, which will minimize proposed
impacts while maintaining a 3:1 ratio with a road width of 16 feet.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Existing graded timber roads have been used in the design of new road construction reducing the amount of excavation on-
site and the amount of vegetation that has to be removed, thus reducing potential erosion and sediment problems. Adequate
erosion and sediment control measures will be employed to capture all sediments generated on-site and will be maintained
through NPDES inspection protocol. Road design allows access to all phased lot sites using driveway standards, which
reduces the total length of subdivision roads on the project site and lowering the total site's impervious characteristics.
Proposed wetland impact site W4 will have a 40'x 18" CMP placed under the fill to convey flow from the wetland and any
additional stormwater runoff. Steps will be taken to minimize disturbance to the wetland bed using surge stone and filter cloth
as fill components which will help to maintain subsurface flow through the impact site. This fill material will be relatively
permeable helping to maintain hydrology below the impact site.
