Mussel Run Headwater Restoration Project
Site Specific Mitigation for Cutter Creek (Greene County, NC)

As-Built Report

1. Introduction

Construction of the Mussel Run Headwater Restoration Project, the off-site mitigation project for
the Cutter Creek development, was completed on April 18, 2008. This project was designed to

provide mitigation for buffer and stream impacts associated with the construction of Lake Nina
within the Cutter Creek development. The mitigation project is located off of Ormondsville Road

near the town of Fourway, NC approximately five miles from the impact area.

This project was reviewed and approved by regulatory staff and the proper permits were obtained
(Action ID# SAW-2007-02828; DWQ Project# 07-0156). Following initial construction, the site will

be monitored for a period of five years. Success will be based on demonstration of appropriate
survivorship and hydrology consistent with wetlands in this landscape position. Following each

monitoring event, a report documenting these aspects will be submitted to regulatory staff.

II. On-site Construction
The first phase of construction involved the removal of the existing road bed. Material from this

road bed was used to fill in two irrigation ponds, totaling 1.2 acres. Finished grades within these
ponds provide a gradual decrease in elevation from the surrounding fields. The second phase

involved the filling of approximately 1,100 linear feet of drainage ditch and removal of a large road
bed present throughout the site. In areas where ditch filling was not appropriate due to hydrologic
trespass concerns, grading was conducted to reduce the amount of channel incision.

The third phase involved the construction of a new 600' channel to provide drainage from the

eastern pond (Pond 1). Grading in this area was configured to mimic a natural "riffle-pool"

sequence found in Coastal Plain streams. A slope of 0.002 was maintained throughout this
portion. The fourth phase involved the construction of a 150' channel to provide drainage from the

western pond (Pond 2) into the existing ditch adjacent to Mussel Run. Similar slopes were

2

maintained for this section. The final phase involved grading and fill work along the northern

portions of the existing stream/ditch network. Grading this area was configured to direct drainage
from the existing fields into Pond 2 and the restored channels.

III. Site Planting

Prior to planting, the entire project area was disked to enhance microtopography and reduce soil
compaction. Following the disking, a five man crew was dispatched to plant 16,000 seedlings

throughout the project area. Each seedling was planted on 8' centers, with an average density 600
stems per acre. A total of six (6) species were planted in one of three different zones, Neuse

Buffer, Cypress-Gum Pond, and Coastal Plain Headwater wetland (Table 1). These zones will
correspond to a frequency of inundation and elevation relative to the reestablished stream

channels. A wetland seed mix was also applied to minimize erosion during the first growing
season.

P - Cypress/Gum Pond 1.2 600

IV. Monitoring Equipment Installation

A total of six (6) 0.10-acre permanent monitoring plots, representing 2% of the project area, were
established. These plots were randomly spaced throughout each of the three main restoration

zones. The success criteria for these areas will be based on survivorship totals which meet or
exceed 320 woody stems per acre at the end of the five year monitoring period. Hydrology within

the site will be monitored using shallow groundwater monitoring wells. A total of three (3) 40-inch
wells were installed throughout the project area. Each well will take daily readings of the current

water table depth. Well data will then be graphed in addition to rainfall totals from the Kinston
airport and presented in the annual monitoring report. In order to meet the appropriate success

criteria, these areas must demonstrate a water table within 12 inches of the soil surface for a
consecutive number of days equal to or greater than 5% of the growing season.

V. Annual Monitoring

The Mussel Run Site will be monitored for a period of five years. Success will be based on
demonstration of appropriate vegetative survivorship and hydrology consistent with wetlands in this

landscape position. Following each monitoring event, a report documenting these aspects will be
submitted to regulatory staff. The first annual monitoring report will be submitted by December 31,

2008.
