construction schedules. No prior iurisdictional determinations or permits have been issued
' for these proiects.
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.
No future proiects are anticipated for this area. Any future proiects would result in the
' appropriate notification at that time.
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: The proposed proiects require the
installation of 6" and 12" ductile iron water piping beneath the stream beds. With the
presence of shallow rock in and along the stream channels, it s_antiClpated that- open-
cutting of the stream channels will be necessary at (4) locations in order to facilitate the
installation of the water lines. Temporary stream impacts will be incurred with the
installation of temporary "coffer dams", excavation of the stream bed and backfilling of
' the trench across the stream. Permanent impacts through the installation of rip-rap
' Page 7 of 13

' material for stabilization of the restored stream bed will be minimized as much as
Aractical, and will be limited to below the_ordinary high water mark. All disturbed
' areas, including the channel armor, will be returned to their pre-construction cross-
section.
' 2. Individually list wetland impacts. Types of impacts include, but are not limited to
mechanized clearing, grading, fill, excavation, flooding, ditching/drainage, etc. For dams,
cer,arately list imnacts due to hnth structure and flooding.

nature and avoidance of stream impacts is not practical. The impacts associated with these
projects' NWP No 12 activities would be mostly temporary in nature and would also be
minimized as much as practical Temporary construction easements will be limited to 40'
maximum Any disturbed portion of the stream channel will be restored to its pre-
construetion elevation and shape Disturbed areas of the streambed and banks will be
stabilized and reinforced with "Class 1" rip-rap stone up to the normal high water mark,
and Long Term Rolled Erosion Control Products are to be utilized above the normal high
water mark on all stream banks. All disturbed areas will then be re-seeded to their current
condition.
All stream crossings will be made at or near 90 degrees to the direction of stream flow. All
activities on the proiect site involving impacts to waters of the U.S. will be required to
adhere to the General Conditions of the Nationwide Permits (Federal Register Vol. 72, No.
47; Monday, March 12, 2007), applicable Wilmington District Regional Conditions, and
applicable State consistency conditions.
Possible sedimentation of the stream during and immediately following the construction
phase of this proiect will be minimized by strict implementation of, and compliance with
state-approved sediment and erosion control plans and devices.
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/strm~ide.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)
' Page 10 of 13

' 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.
Due to the linear nature of these proiects avoidance of impacts to waters of the U.S.,
including the watershed buffers, is not possible. Due to the channelized natures
"urbanized" condition of the existing stream banks (maintained grass), and the aspect
of this being a temporary impact, the City of Greensboro is not proposing mitigation
' for these proiects.
2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement
Program (NCEEP). Please note it is the applicant's responsibility to contact the NCEEP at
' [phone] to determine availability, and written approval from the NCEEP indicating
that they are will to accept payment for the mitigation must be attached to this form. For
additional information regarding the application process for the NCEEP, check the NCEEP
website at http•//h2o enr.state.nc.us/wrp/index.htm. If use of the NCEEP is proposed, please
check the appropriate box on page three and provide the following information:
Amount of stream mitigation requested (linear feet): None
Amount of buffer mitigation requested (square feet): None
Amount of Riparian wetland mitigation requested (acres): N/A
' Amount ofNon-riparian wetland mitigation requested (acres): N/A
Amount of Coastal wetland mitigation requested (acres): N/A
' IX. Environmental Documentation (required by DWQ)
1. Does the project involve an expenditure of public (federal/state/local) funds or the use of
public (federal/state) land? Yes ® No ^
2. If yes, does the project require preparation of an environmental document pursuant to the
requirements of the National or North Carolina Environmental Policy Act (NEPA/SEPA)?
Note: If you are not sure whether a NEPA/SEPA document is required, call the SEPA
coordinator at [phone] to review current thresholds for environmental documentation.
Yes ^ No
' 3. If yes, has the document review been finalized by the State Clearinghouse? If so, please
attach a copy of the NEPA or SEPA final approval letter. Yes ^ No ^
' X. Proposed Impacts on Riparian and Watershed Buffers (required by DWQ)
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
' required state and local buffers associated with the project. The applicant must also provide
justification for these impacts in Section VII above. All proposed impacts must be listed herein,
and must be clearly identifiable on the accompanying site plan. All buffers must be shown on a
' map, whether or not impacts are proposed to the buffers. Correspondence from the DWQ
Regional Office may be included as appropriate. Photographs may also be included at the
applicant's discretion.
' 1. Will the project impact protected riparian buffers identified within 15A NCAC 2B .0233
(Meuse), 15A NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 02B .0243 (Catawba) 15A NCAC
Page 11 of 13

' 2B .0250 (Randleman Rules and Water Supply Buffer Requirements), or other (please
identify )? Yes ~ No ^
2. If "yes", identify the square feet and acreage of impact to each zone of the riparian buffers.
If buffer mitigation is required calculate the required amount of mitigation by applying the
buffer multi liers.
' Zone* Impact Multiplier Required

' * Zone 1 extends out 30 feet perpendicular from the top of the near bank of channel; Zone 2 extends an additional
20 feet from the edge of Zone 1.
3. If buffer mitigation is required, please discuss what type of mitigation is proposed (i.e.,
Donation of Property, Riparian Buffer Restoration /Enhancement, or Payment into the
' Riparian Buffer Restoration Fund). Please attach all appropriate information as identified
within 15A NCAC 2B .0242 or .0244, or .0260. Due to the "urbanized" condition of the
existing stream banks (thoroughly maintained grass), the protect location being within
the maintained area of the Sedgefield Country Club golf course, and there being no
practical alternative per 15A NCAC 02B .0250, the City of Greensboro is not seeking
' mitigation for these impacts.
XI. Stormwater (required by DWQ)
Describe impervious acreage (existing and proposed) versus total acreage on the site. Discuss
stormwater controls proposed in order to protect surface waters and wetlands downstream from
the property. If percent impervious surface exceeds 20%, please provide calculations
demonstrating total proposed impervious level. No significant additional impervious area is
to be added as a result of these proiects.
' XII. Sewage Disposal (required by DWQ)
Clearly detail the ultimate treatment methods and disposition (non-discharge or discharge) of
wastewater generated from the proposed project, or available capacity of the subject facility.
No wastewater generation is proposed.
XIII. Violations (required by DWQ)
' Is this site in violation of DWQ Wetland Rules (15A NCAC 2H .0500) or any Buffer Rules?
Yes ^ No
Is this anafter-the-fact permit application? Yes ^ No
' XIV. Cumulative Impacts (required by DWQ)
' Will this project (based on past and reasonably anticipated future impacts) result in additional
development which could impact nearby downstream water quality? Yes ^ No
If yes, please submit a qualitative or quantitative cumulative unpact analysis m accordance with
' the most recent North Carolina Division of Water Quality policy posted on our website at
http://h2o.enr.state.nc.us/ncwetlands. If no, please provide a short narrative description: The
proposed proiects are to provide a potable water supply to existing residences only. No
' additional development is anticipated.
