The Parcel was restored to provide ecological and water quality enhancements to the Neuse River Basin by restoring the riparian buffer along four unnamed tributaries (UT1, UT2, UT3, and UT4), and three ditches (Ditches A, B, and C). The Parcel creates a protected riparian area from top of bank to a minimum of 30 feet along streams, or 50 feet along ditches, to a maximum of 200 feet. Prior to mitigation activities most of the Parcel was used to produce row crops, with small, forested areas at the downstream end of UT1 and UT2. Tables 1 and 2 contain project overview and credit applicability information. Table 1.

Of that 21.6 acres of restoration, 9.6 acres are proposed for buffer mitigation credit and 12.0 acres are proposed for nutrient offset credit. Buffer preservation credits are also proposed on 0.27 acres within the conservation easement. The Buffer Interpretation/Clarification Memo #2008-019 applies to Ditches B and C where maintenance of diffuse flow into the easement is unattainable. A total of 0.07 acres (or 3,079 square feet) have been removed from the creditable area around these ditches. Other areas within the conservation easement where no credit is claimed include areas which are over 200 feet from top of bank, the project feature channels, and the area which is less than 50 feet from top of bank along Ditch C. The land use within 200 feet from top of bank of the project features had been maintained and cleared for row crop cultivation prior to restoration activities, except for the pond that was filled prior to the BPDP near the confluence of UT1 and UT3 and a small, forested area along UT1. Bare root trees were planted using a dibble bar at a spacing of 7 feet by 12 feet, which resulted in a stem density of 561 stems per acre. Soils in the project area were disked and planted with wheat and oats by the landowner as temporary cover and soil stabilization for the winter. Three erosion areas along UT1 were stabilized by live staking banks and in one case grading the bank by hand to reduce the slope before live stakes were planted. The sides of a large erosional hole on the southeast bank of UT2 were graded by hand, straw bales were installed around the edge to diffuse overland flow, and live stakes were planted in the graded slope. Erosional areas on the northeast bank of Ditch C and UT3 were stabilized by installing straw bales to divert overland flow or live staking banks that were bare of vegetation. A temporary seed mix and pollinator blend was spread around all areas of bank stabilization. Table 3 includes a list of tree species planted along with their density and composition at planting.

Boundaries are identified by 6 foot "t posts" with attached easement placards. Signage along the outer perimeter of the Parcel has been placed at 100-foot intervals.
