.~.,~
Enclosed is a 401 Water Quality Certification application for your review. This application is
submitted on behalf of Autumn Hall Incorporated for the Autumn Hall Town Center in Wilmington, NC.
The applicant is proposing to construct amixed-use development with 281 single-family lots, 33
townhomes, and a town center with offices, retail stores, condominiums, and a hotel. Although the applicant
has attempted to minimise impacts through careful site design, approximately 0.151 acre of 404 wetland
impacts (0.13 acre permanent) and 279 linear feet of stream impact (203 LF permanent) are proposed.
These impacts are needed for road crossings, installation of a storm drain, and replacement of a culvert. To
mitigate for the permanent impacts, the applicant proposes to restore 79 LF of stream on site, preserve all
remaining wetlands and streams on the site, and buy into the EEP for the restoration of 124 LF of stream.
The Pre-Construction Notification form, associated maps, and site plan are enclosed for your
review. In addition, the $200 application fee has been submitted to your Raleigh office. Please contact me if
you have any questions. Thank you for your assistance with this project.
Sincerely,
Kim Williams

financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts. The applicant has taken great
care in the site design in order to minimize impacts 404 wetlands and streams. However, the tip
of two wetland finders (#1 and #2) will be disturbed by the side slopes of proposed roads.
Another wetland areal#3) will be temporarily impacted from the installation of a storm drain.
Three stream crossin>;s are needed Stream impact #1 is needed to tie the subdivision into Clear
Run Drive as required by the County This crossins; is relatively long (194 LF) because of the
irregular shape of the property boundary in this area and the need to maintain proper road
curvature Another small stream impact is needed for a road crossing. This crossing consists
mostly of an existing crossing (only 8 LF of new impact and 61 LF of current stream impact
will be removed as restoration Finally the applicant will also replace an existing culvert under
Clear Run Drive with a box culvert, as required by the County. No new impacts are needed at
this location.

VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on January 15, 2002, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCEEP concurrence shall be placed on hold as incomplete.
An applicant may also choose to review the current guidelines for stream restoration in DWQ's
Draft Technical Guide for Stream Work in North Carolina, available at
http://h2o. enr.state. nc.us/ncwetlands/strmgide.html.
1. Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
The applicant proposes to restore 79 LF of stream on site (two areasLpreserve all remaining
wetlands and streams on site and b~ into the EEP for the restoration of 124 LF of stream.

1.0 Introduction
In order to compensate for proposed permanent wetland and stream impacts located within
the Autumn Hall Town Center project in New Hanover County, the applicant, Autumn Hall
Incorporated, will restore 791inear feet of stream on site, preserve remaining wetlands and streams
on site, and buy into the Ecosystem Enhancement Program (EEP).
The site is approximately 203 acres in size and is located off of Eastwood Road in
Wilmington, NC. The applicant proposes to restore two sections of astream on-site by removing old
fill material and culverts. A variety of native wetland shrub and tree species will be planted along the
stream banks in these areas.
2.0 Site Description
This site is 203 acres in size and is the old Duck Haven Golf Course. It contains
approximately eleven acres of wetlands. Bradley Creek forms the eastern and southern boundaries of
the tract and two unnamed tributaries run from Bradley Creek northward into the site. Soils within
the site are classified as Kureb sand, Baymeade fine sand, and Seagate fine sand in uplands and
Johnston loam in wetlands (Figure 4). Vegetated 404 wetlands within the site contain water oak
(Quercus nigra) wax myrtle, (Myrica cerifera), loblolly bay (Gordonia lasianthus), red maple (Ater
rubrum), and black willow (Salix nigra). Most of the uplands are maintained in a mowed condition.
3.0 Stream Restoration
In two locations, an existing roadway and culvert will be removed and the stream channel
will be reformed. The width of the restored stream will be that of the existing adjacent stream and the
banks will shaped at a 3 to 1 slope. Stream Restoration Area # 1 is 61 linear feet in length and Stream
Restoration Area #2 is 9 feet in length. Vegetation to be planted along the banks of each of these
restored areas will include species growing along adjacent stream sections (Table 1). These species
will be planted on a 3' spacing.
4.0 Monitoring
A general site analysis will occur directly after mitigation activities have been completed and
3

will consist of taking photographs of the restored streams to evaluate initial success. A small
narrative will be written and submitted to the Corps and DWQ. From then on, monitoring will occur
annually for up to five years (if the agencies determine the site to be successful prior to five years,
monitoring will discontinue). During each monitoring event, the vegetation within the restored
stream bank will be counted and identified. Success criteria will be the survival of at least 70% of
planted vegetation. A monitoring report that summarizes these results and includes photographs of
the restored areas will be submitted to the Corps and DWQ. Because of the small size of the
mitigation areas, hydrological monitoring will not occur. However, the survivorship of wetland
plants within the area will provide a good indication of hydrology success.
5.0 Implementation Schedule
Stream mitigation activities will commence as soon as the ACOE and DWQ have an
opportunity to review and approved this document.
6.0 Summary
In order to compensate for proposed permanent wetland and stream impacts within Autumn
Hall Town Center in New Hanover County, the owner of the tract will restore streams on-site by
removing fill material and existing culverts. These areas will be planted with native wetland
vegetation. A general site analysis will occur directly after mitigation activities have been completed
to evaluate initial success. From then on, monitoring will occur annually for up to five years. In
addition, all remaining wetlands and streams on site will be preserved in perpetuity through
restrictive covenants. Finally, payment will be made to the Ecosystem Enhancement Program for the
restoration of 124 LF of stream.
