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 cleazly defined. For administrative and distribution purposes, the
USACE requires information to be submitted on sheets no lazger 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 aze
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 aze provided.

Page 6 of 13

the lake. The property surrounding the lake eg_nerally consist of single-family homes, a
clubhouse with pool and tennis courts, and a real estate office.
10. Describe the overall project in detail, including the type of equipment to be used: The
project consists of the placement of a keystone segmental block retaining wall (block size
18"b~) along~the eroded lake banks on the western end of the lake. The lake level will be
lowered about 18", a wall footing 24" wide and 12 to 18" deep (below the exposed mud line
will be excavated with amini-excavator, the footing` excavation will be lined with a
geotextile, approx. 8" of washed stone will be placed on the fabric with a bobcat loader, then
the blocks will be stacked and secured according~to manufacturer's specifications. A
minimum of 4" of block will be present below the mud line, and the maximum wall height
above the mudline will be 3.5'. The wall will vary in hei t due to variation in hei t of the
eroded lake bank.
11. Explain the purpose of the proposed work: Erosion has created vertical erosion Ovals along
the lake and in places has undermined lake banks and trees. The property immediately
adjacent to the lake is common property (owned by the entire community). This community
property is disappearing into the lake at an alarmin rg ate (up to 1' per yeaz).
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. A permit was issued and approved for this type of work on October
2006.
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.
We will request additional approvals in the future to install similaz retaining walls around the
majority of the lake. This work is not being included in this application because we don't know
exactly where we would like to place the next sections.

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 cleazly 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: 'The presence of the dam
downstream of the project and all work being_performed while no water is going over the
weir means no negative impact to the lake or Bull Run Creek The prevention of erosion at
the lake banks due to the construction of walls should have a positive impact on the lake and
Bull Run Creek.
2. Individually list wetland impacts. Types of impacts include, but aze not limited to

VII. Impact Justification (Avoidance and Minimization)
Expected pond surface area:
Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
fmancial 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 lake level will be below the
top of the dam overflow weir during wall construction to minimize and disturbed sediment from
entering Bull Run Creek. The wall will be placed slightly on the lake side of erasion walls
wherever possible to limit disturbance of the lake banks.
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 (see DWQ website for most current
version.).
