Executive Summary a-,Y l
April 22, 2010
The LaForesta Creek Stream Mitigation Bank ("Bank") will be planned and designed in one phase
encompassing land along an unnamed tributary to North Buffalo Creek in Guilford County, NC. The
purpose of the Bank is to provide Stream Mitigation Credits to compensate for impacts to Waters of the
United States and/or State Waters within the service area, Hydrologic Unit 03030002.
Project Location
The proposed Bank site is located at the end of LaForesta Drive, Greensboro, North Carolina . The site
itself is completely cleared pasture, but is located in a highly urbanized watershed within the Cape Fear
River Basin (HUC 03030002). The site is immediately downstream from a commercial and residential
region associated with Hicone Road in Greensboro.

Project Goals
The plan for the LaForesta Stream Mitigation Site involves the restoration of dimension, pattern, and
profile of approximately 5,337 linear feet of perennial stream channel. As a result of the proposed
restoration activities, total stream length within the project area will be increased from approximately
5,337 linear feet to 6,130 linear feet. The proposed stream restoration designs will primarily include
Rosgen a Priority Level 1 approach and the stream types for the restored streams will be a Rosgen C
channel with design dimensions based upon reference reaches and past projects. Based on the
proposed mitigation effort, the bank site will result in 6,130 stream credits (figure 1).
Current Water Quality Impairments
The site itself is completely cleared pasture and is located in a highly urbanized watershed within the
Cape Fear River Basin (HUC 03030002). The site is immediately downstream from a commercial and
residential region associated with Hicone Road in Greensboro.
The site drains directly into North Buffalo Creek. North Buffalo Creek is included on the North Carolina
Division of Water Quality (NCDWQ) 303d list of impaired water bodies due unknown causes to biota.
The proposed stream and riparian buffer mitigation project described above will provide numerous
ecological benefits within the Cape Fear River Basin. While many of these benefits are limited to the
project area, others, such as pollutant removal and improved aquatic and terrestrial habitat have more
far-reaching effects.
Proposed Service Area
The Bank will be established to provide mitigation to compensate for impacts to Waters of the United
States and/or State Waters within the Haw watershed service area. This service area shall include
Hydrologic Unit 03030002, including portions of the Cities of Greensboro, Burlington, Graham, Carrboro,
Chapel Hill, Durham, Pittsboro, Cary, and Reidsville and the Counties of Rockingham, Guilford,
Alamance, Caswell, Orange, Chatham, Durham, and Wake.
Need and Feasibility of Mitigation Bank
The Cape Fear 0303002 includes developing areas such as the cities of Greensboro, Durham, Burlington
and Chapel Hill as well as the 1-40/ 1-85 transportation corridor. Population growth and the associated
development and infrastructure projects create the necessity for mitigation banks in this region.
Mitigation banks will allow unavoidable impacts to Waters of the United States to be mitigated for
appropriately and allow the economic growth of this region to continue while the environment and
water quality remain a priority.
Based on the results of the preliminary investigations that have taken place on the Bank site, it was
determined that the subject site has substantial potential for development of a private mitigation bank.
The majority of the stream systems on the site show substantial degradation including incision, bank
erosion, sedimentation, and lack of in-stream habitat structure. A large portion of one of the streams on
site has been filled in resulting in a low muddy area.
Duke Power maintains a high tension power right-of-way immediately above the existing stream
channel. This location is frequently cleared leaving little to no vegetation in the stream bank or
floodplain. Consequently the significant portions of the existing stream are severely eroded and
contributing massive amounts of sediment into the stream system.
Design Concept
Most of the existing stream is within the Duke Power easement. Historically the stream has meandered
throughout the valley in various configurations. In addition a major stream alignment change was made
in the late 1970's moving a significant amount of flow into the present location (figure 2).
The design approach will be to relocate the stream outside of the Duke Power easement into what is
suspected to be the former stream location. This will require a shift of approximately 50 feet from the
streams' present location. The stream's pattern, dimension and profile will be based upon local
reference reach data. It is expected that the stream type will be a Rosgen type C-4 (gravel-bed) stream.
