Dear Chad:
oq- kaz'bVa
ft.. J UP
Enclosed is a 401 Water Quality Certification application for your review. This
application is submitted on behalf of LCFUMB, LLC for the construction of the White Springs
Tract - a portion of the Lower Cape Fear Umbrella Mitigation Bank located in Brunswick
County, NC. The applicant is proposing to plug and backfill 1.37 acres of existing jurisdictional
ditches and fill 1130 LF of incised stream in order to develop a large -scale wetland and stream
mitigation bank in the Cape Fear 03030005 basin per the approved mitigation plan.
The Pre - Construction Notification form, associated maps, and site plan are enclosed for
your review. The DWQ application fee of $570 has been submitted to your Raleigh office.
Please contact me if you have any questions. Thank you for your assistance with this project.
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.
Proposed impacts are unavoidable due to the type of project proposed. In order to restore and enhance riverine wetlands
formerly occurring on the property (via hydrologic restoration), the identified canals /ditches must be plugged and /or filled.
Little to no in- stream habitat has developed within the ditches and canals within the property and an overall benefit to
downstream water quality is expected as a result of project implementation.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Locations of the proposed backfill and plugs were selected based on the existing drainage network. Sediment and
erosion control plans will be prepared and submitted for each section of the project. The protective measures detailed in
these plans will eliminate discharge of sediments to off -site water bodies. No earthwork will be conducted until receipt of
approval of the erosion and sediment control plan by the NC Division of Land Resources.

The NC Natural Heritage Program GIS layer was used to determine the presence of federally listed species. According to
their database, a population of Venus flytrap (Dionaea muscipula; FSC; SC) has been observed within the powerline corridor
that runs through the site. Several state - listed and federally - listed species have been identified within a one -half mile radius of
the site. Of particular note is the documented presence of red - cockaded woodpecker (RCW) (Picoides borealis) in the vicinity
of the White Springs Tract, both on the adjacent federal Military Ocean Terminal at Sunny Point and within the nearby
community of Boiling Spring Lakes. The eastern portion of the White Springs tract includes longleaf pine savanna habitat
suitable for nesting and roosting RCW. The mitigation bank project will result in the protection of the longleaf pine savanna
occurring on the property.

or cultural resources. No resources were noted within or adjacent to the project area.
8. Flood Zone Designation (Corps Requirement)
8a. Will this project occur in a FEMA- designated 100 -year floodplain?
❑ Yes ® No
8b. If yes, explain how project meets FEMA requirements:
