D. Impact Justification and Mitigation
1. Avoidance and Minimization
1 a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
All sandbars will be excavated in sections (stepped back) to minimize erosion/sediment leaving defined target area. Erosion matting and riprap will be
used on a case by case bases along with silt fence in areas of concern. Matting may be used on portion of right of way to minimize impact to soils and
integrity of slope. Spoils material's will be placed on uplands of right of way and will be spread and seeded.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Each sandbar's slope will be benched back one section at a time. A buffer will be left in place between excavated area and flow of ditch. Buffer will
reduce materials from entering flow of ditch and buffer will be excavated/graded to slope in final step towards completion of sandbar. All areas will be
seeded and will have erosion prevention materials added as needed.

Appendix 1
Shingletree and Hickman Rd Canals Project
PCN Section Text Clarification
3e. Describe the overall project in detail, including the type of equipment to be used:
Objective :To excavate proposed sandbars from Caw Caw drainage ditch (HWY 17 & Shingletree
RD, Hickman RD & Meadowlands GC, #5 School House RD). Sandbars are above the normal high
water mark and will be excavated in sections (stepped back) to minimize erosion. All materials
will be placed on uplands to dry and then spread along right of way. All disturbed areas will be
seeded and erosion matting/ riprap used as needed. Stepped Back or bench slope action: Each
sandbar's slope will be benched back one section at a time. A buffer will be left in place
between excavated area and flow of ditch. Buffer will reduce materials from entering flow of
ditch and buffer will be excavated/graded to slope in final step towards completion of sandbar.
All areas will be seeded and will have erosion prevention materials added as needed.
5b. If yes, explain in detail according to "help file" instructions.
The Caw Caw Swamp watershed was initiated in 1964 with the state of North Carolina, Us
Department of Agricultures and Brunswick County. The Watershed work plan and the as built
plans are on record with the USACE regulatory branch.
