Impact Justification {Avoidance and Minimization) Avoidance measures; The access point to the public road system far this project site is the Burgaw Highway {NC 53). The site is bounded to the east by small parcels with wetlands that are individually owned, to the north by lots in an adjacent subdivision and Blue Creek, 'to west by a large parcel of undeveloped land with small trees and open fields and to the south by Burgaw Highway (NG 53). One of the wetkand fingers in this area extends across the entire width of the propErty from east to west. In order to get to the northern park of the parcel, the wetlands must be crossed. There are no other public roads adjacent to this site other than Burgaw Highway (NC 53), thus providing access to this development will require the crossing of these wetlands. Alternate site plans were considered, but since they all require access from Burgaw Highway, they also resulted in filling the wetlands. The other site plans do not reduce the impact to wetlands and provide a less desirable road alignment and lot configuration and therefore were rejected. Constructing a bridge over the wetlands at Engineer's Stataon 11+60 would completely avoid impacting them, but this would require a bridge span of at least 65 feet. This would increase the maintenance costs for the roadway and would be cost prohibitive to the owner. It was therefore was rejected. It is not possible to avoid all impacts to wetlands and provide access to the proposed lots. Minimization measures: Alternate road design standards were explored, but since these subdivision roads will be taken over by the North Carolina Department of Transportation Standards they must be constructed to their minimum standards. These streets will be constructed with a 20-foot roadway surface, a 6-foot shoulder, and 4:1 side slopes. l-owering the roadway standards below this would reduce the safety of the road for the residents and visitors to the proposed single-family residences and would make them ineligible to be included in the NCDOT Secondary Road System. Therefore reducing the roadway standards is not a feasible alternative. Headwalls will be constructed at both the inlet and outlet of the double 48~inch culverts at Engineer's Station 11+Gfl. This will eliminate the need for flared end sections that would extend 8.25 feet further into the wetlands, thereby minimizing the impact to the wetlands. There are no other minimization measures known.
