landmarks such as towns, rivers, and roads. Also provide a detailed site plan showing property
boundaries and development plans in relation to surrounding properties. Both the vicinity map
and site plan must include a scale and north arrow. The specific footprints of all buildings,
impervious surfaces, or other facilities must be included. If possible, the maps and plans should
include the appropriate USGS Topographic Quad Map and NRCS Soil Survey with the property
boundaries outlined. Plan drawings, or other maps may be included at the applicant's discretion,
so long as the property is clearly defined. For administrative and distribution purposes, the
USACE requires information to be submitted on sheets no larger than 11 by 17-inch format;
however, DWQ may accept paperwork of any size. DWQ prefers full-size construction
drawings rather than a sequential sheet version of the full-size plans. If full-size plans are
reduced to a small scale such that the final version is illegible, the applicant will be informed that
the project has been placed on hold until decipherable maps are provided.
1. Name of project: Glenwood Forest Subdivision
2. T.I.P. Project Number or State Project Number (NCDOT Only):
3. Property Identification Number (Tax PIN): 785392704
4. Location
County: Wake Nearest Town: Raleigh
Subdivision name (include phase/lot number): Glenwood Forest
Directions to site (include road numbers/names, landmarks, etc.): From 440 Beltline, drive
west to Highway 70/Glenwood Avenue Exit (Exit 7). Take Highway 70 north toward
Durham. The site is located approximately 3.0 miles from the Beltline. Site is
located on the right side (south side) of Glenwood Avenue approximately 1800 feet
from the Glenwood Ave./Duraleigh Road Intersection.
5. Site coordinates (For linear projects, such as a road or utility line, attach a sheet that
separately lists the coordinates for each crossing of a distinct waterbody.)
Decimal Degrees (6 digits minimum): 35.8995 °N 78.7202 °W
6. Property size (acres):
7. Name of nearest receiving body of water: Turkey Creek
8. River Basin: Neuse
(Note -this must be one of North Carolina's seventeen designated major river basins. The
River Basin map is available at http://h2o.enr.state.nc.us/admin/maps/.)
9. Describe the existing conditions on the site and general land use in the vicinity of the project
at the time of this application: The land use varies in the immediate area and includes
Page 2 of 9

commercial residential State Park Land (Umstead State Park), cemetery, and mining
(rock quarry).
10. Describe the overall project in detail, including the type of equipment to be used:
In a Notice of Violation (NOV) issued by the Division of Water Quality on January 9,
2006 two stream crossings ons~te were cued for being improperly installed. The
attached stabilization plan was developed to address these culvert pipes and the
subsequent impairment of the stream channels due to their improper placement.
The proposed stream stab~l~zat~on includes the installation of a series of J-hooks and
rock cross vanes in order to stabilize 357 I~near feet of existing impaired channel.
Please see the included plan sheets for add~t~onal details. Typical heavesequipment
for stream restoration will be used.
11. Explain the purpose of the proposed work: in 2006, a NOV was issued for the failure to
comply with the conditions of the 401 Water Quality Certification, spec~f~cally for
failing to install culverts below the stream elevation for water and aquatic life
passage. The purpose of the~roposed work is to reconnect the down-cut stream
channel downstream of each improperly installed culvert to allow for aquatic passage.
Rock J-hooks and Cross Vanes will be used in the restored sections to provide
grade control relieve near bank shear stress, and dissipate energy.
IV. Prior Project History
If jurisdictional determinations and/or permits have been requested and/or obtained for this
project (including all prior phases of the same subdivision) in the past, please explain. Include
the USACE Action ID Number, DWQ Project Number, application date, and date permits and
certifications were issued or withdrawn. Provide photocopies of previously issued permits,
certifications or other useful information. Describe previously approved wetland, stream and
buffer impacts, along with associated mitigation (where applicable). If this is a NCDOT project,
list and describe permits issued for prior segments of the same T.I.P. project, along with
construction schedules. On July 19 2006, SPEC submitted a PCN on behalf of Glenwood
Avenue Associates LC. for the proposed Glenwood Forest Subdivision. These impacts
were permitted and included the installation of two stream crossings and the installation
of utilities onsite. The PCN was approved by DWQ on September 14, 2006. There
was a NOV issued for failure to comply with the conditions of the 401 Water Quality
Certification specifically for failing to install culverts properly. A stream stabilization
plan has been developed by SPEC and is included in this application package.
V. Future Project Plans
Are any future permit requests anticipated for this project? If so, describe the anticipated work,
and provide justification for the exclusion of this work from the current application.

VI. Proposed Impacts to Waters of the United States/Waters of the State
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
wetlands, open water, and stream channels associated with the project. Each impact must be
listed separately in the tables below (e.g., culvert installation should be listed separately from
riprap dissipater pads). Be sure to indicate if an impact is temporary. All proposed impacts,
permanent and temporary, must be listed, and must be labeled and clearly identifiable on an
accompanying site plan. All wetlands and waters, and all streams (intermittent and perennial)
should be shown on a delineation map, whether or not impacts are proposed to these systems.
Wetland and stream evaluation and delineation forms should be included as appropriate.
Photographs may be included at the applicant's discretion. If this proposed impact is strictly for
wetland or stream mitigation, list and describe the impact in Section VIII below. If additional
space is needed for listing or description, please attach a separate sheet.
1. Provide a written description of the proposed impacts: No permanent impacts are
proposed. Temporarypacts due to the stream stabilization are approximately 357
linear feet. This length of channel (an unnamed tributary to Turkey Creek) will be
stab~l~zed utilizing in-stream structures, including a series of rock cross vanes and
2. Individually list wetland impacts. Types of impacts include, but are not limited to

Specifically describe measures taken to avoid the proposed impacts. It maybe useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
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. Efforts will be made to
disturb the channel and existing buffer as little as possible, while utilizing natural channel
design pr~nc~ples to provide a stable channel.
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.

proceeds. Contractor shall not disturb more channel length than can be restored and stab~hzed m a single
2. Notify NCDENR (Land Quality section) ten days prior to construction, day.
3. Locate and mark existing utilities on site.
4. Install temporary sediment ~ erasion control measures as shown on plans, access roads, staging area, temporary stream
crossings, and temporary facilities. All installed temporary sediment and erosion control measures will be inspected weekly or
after a mayor rainfall event (> 0.5 inches) by the Contractor. Upon inspection, any necessary repairs will be performed by the
Contractor.
5. Clear and grub in required areas for stream stabilization. Contractor shall not disturb more channel length than can be
restored and stabilized in a single day. Stockpile excess fill m areas as directed by Engineer. Surround stockpile areas with 2
rows of silt fence.
6. Install silt fence and gravel check dam immediately downstream of the proposed channels' terminus, and any additional silt
fencing at the Engineer's and/or Contractor's discretion.
7. Install cofferdam (impervious dike) immediately above the start point of the channel segment to be constructed. Install pump
around operation. install temporary splash pad at outfall ~f necessary (refer to pump around operation notes on Erosion
Control Details). Relocate pump around operation as channel construction proceeds downstream.

9. Apply erosion control seeding measures to disturbed areas as final grade is reached. Contractor shall
stabilize all slopes outsde of channel banks which are 311: I U or steeper with excelsior matting.
10. Remove gravel check dam, cofferdam, pump around equipment, and any other
temporary erosion control devices installed for the purposes of construction.
I I . Apply sod ammendments as needed to prepare for seeding and planting. Perform buffer planting as specified.
Engineer to be notified prior to planting observation to approve planting bed conditions.
12. Apply permanent seeding measures. Remove temporary sediment ~ erosion control measures once site is
stabilized.
