DWQ Project #: 08-0425
Dear Ms. Chapman,
I've included a brief response to your request for additional information below.
You asked for the following information:
s) Please provide the impacts and mitigation amounts required to satisfy mitigation
requirements for parallel impacts to Zone 1 of the Buffer.
The PCN has been updated to include this information. Parallel impacts to Zone s
include s2, z36 SF(o.z79 acres).
2) Please provide a planting plan that details where the trees are going to be
planted, when they will be planted and the tree species to be planted for the
restoration.
A planting plan is included with the attachments. The City ofRaleigh anticipates
beginning the restoration work in the Fall of ZooB. Tree species will be selected
based on what is available from the Forest Service at the time of planting Only
native plants will be selected for this project and at least 3 different species will
be installed along the creek banks Planting protocols/design will be consistent
with the NCEEPGuidelines forRiparian BufferRestoration (ZOOS).
Please note that due to the urban environment, there are a number of locations
along the abandoned sewer line that cannot be re-forested. As detailed in the
attached photos, existing structures (e.~: driveways, carports, flower beds) limit
our ability to restore the buffers. Additionally, there are also areas within the
easement that have not been maintained, and therefore, have become densely
vegetated (see photos). We do not believe that these areas will benefit form
additional plantings, the City will insure that these sections of the abandoned
easement remain undisturbed. Photos of the restoration sites are also included
with the attachments.
We trust this information will allow you to complete your review of this project. Please
feel free to call if you have questions or require additional information.

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: Cemetery Branch Sanitary Sewer Replacement
2. T.I.P. Project Number or State Project Number (NCDOT Only): NA
3. Property Identification Number (Tax PIN):_
4. Location
County: Wake Nearest Town: Raleigh
Subdivision name (include phase/lot number): NA
Directions to site (include road numbers/names, landmarks, etc.): The subject area is
located in downtown Ralei hg_adjacent to Cemetery Branch Creek, between Capitol Blvd and
North Boundary St.
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): 35.8018837 °N 78.6221736 °W
6. Property size (acres): Linear Project 5100'
7. Name of nearest receiving body of water: Cemetery Branch
8. River Basin: Neuse River Basin
(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: Approximately half of the project will be confined to an
existing sewer easement. The land use within the vicinity of the project consists of residential
yards and roads/parking lots.
10. Describe the overall project in detail, including the type of equipment to be used: This
project consists of replacing ig_ng sewer line that is currently located adjacent to
Cemetery Branch Creek. A majority of the existing easement is within 5 feet of the creek
and runs parallel on zone 1 and zone 2 of the buffers. In two areas, the existing line is
Page 2 of 9

actually runs along the base of the stream. Large excavating equipment (i e trackhoe) will
be used to install the sewer line.
11. Explain the purpose of the proposed work: The purpose of this project is to protect water
quality by replacing the existin line (i.e. prevent spills) and movin ig 't away from the creek
banks wherever possible. The current line constructed of cla~pipe with joints every 3 feet
will be replaced by a metal pipe with fewer joints reducing the risk of spills and extending
the life of the sewer line.
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. Wetlands were delineated by Withers &Ravenel and an upland data
form is included with the attachments. On January 18 2008 apre-application meetin was
conducted with Ms. Amy Chapman of the NC-DWO to review the proposed impacts to the
riparian buffers needed to rehabilitate the sewer line On February 28 2008 a second meeting
was conducted with Ms. Amv Chapman and members of the City of Raleigh Public Works and
Withers &Ravenel to discuss mitigation requirements. Because one component of this project is
to protect water quality and move the sewer line away from the creek it was determined that in
area where the existing sewer line is abandoned the applicant will re-plant the riparian buffer to
satis mitigation requirements.
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 additional impacts are proposed at this 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
Page 3 of 9

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 impacts consist
of 38 linear feet of importandperennial stream and 0.87 acres of riparian buffer (Zone 1:
15,572 SF & Zone 2: 22,260 SF) for the installation of this utilit line.
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,
separately list impacts due to both structure and flooding.

Describe all impacts to isolated waters, and include the type of water (wetland or stream) and
the size of the proposed impact (acres or linear feet). Please note that this section only
applies to waters that have specifically been determined to be isolated by the USACE.
NA
8. Pond Creation
If construction of a pond is proposed, associated wetland and stream impacts should be
included above in the wetland and stream impact sections. Also, the proposed pond should
be described here and illustrated on any maps included with this application.
Pond to be created in (check all that apply): ^ uplands ^ stream ^ wetlands

draw-down valve or spillway, etc.): NA
Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond,
local stormwater requirement, etc.): NA
Current land use in the vicinity of the pond: NA
Size of watershed draining to pond: NA Expected pond surface area: NA
VII. Impact Justification (Avoidance and Minimization)
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
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. Prior to the design_process, the
applicant requested that detailed wetland delineation be conducted so that impacts to wetlands
and `waters' could be minimized. The existing sewer line is located almost exclusively in Zone
1 and Zone 2 of the buffer or, within the channel of Cemetery Branch. The replacement sewer
has been designed to minimize impacts to the riparian buffer and move it farther away from the
creek. Approximate1~16,298 square feet of line will be abandoned in Zone 1 of the buffer and
re-planted with bare root seedlings (wherever possible, or allowed to re-vegetate, and 5,885 of
Zone 2 will be abandoned and re-seeded with fescue. However, due to existing houses and
structures, the sewer line could not be located entirely outside of the 50-foot buffer. Whenever
possible, the work will be confined to the previously disturbed areas in Zone 2.
VIII. Mitigation
DWQ - In accordance with I SA 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.
Page 5 of 9

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://h2 0. enr.state.nc. us/ncwetl ands/strm gi d e.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.
Because the stream impacts are temporary and will be returned to pre-construction contours,
the applicant does not propose mitigation for the stream crossings. Approximately 16,298
square feet of line will be abandoned in Zone 1 of the buffer and re-planted (wherever
possible) or allowed to re-vegetate, and 5,885 square feet of Zone 2 will be abandoned and
re-seeded with fescue to satisfy mitigation requirements.
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 five and provide the following information:
Amount of stream mitigation requested (linear feet): NA
Amount of buffer mitigation requested (square feet): NA (see below)
Amount of Riparian wetland mitigation requested (acres): NA
Amount ofNon-riparian wetland mitigation requested (acres): NA
Amount of Coastal wetland mitigation requested (acres): NA

re-vegetate, and 5,885 square feet of Zone 2 will be abandoned and re-seeded with fescue to
satis mitigation requirements.
A planting plan is included with the attachments. The City of Raleigh anticipates
beginning the restoration work in the Fall of 2008. Tree species wil[ be selected based
on what is available from the Forest Service at the time of planting. Only native plants
will be selected for this project and at least 3 different species will be installed along the
creek banks. Planting protocols/design will be consistent with the NCEEP Guidelines for
Riparian Buffer Restoration (200
Please note that due to the urban environment, there are a number of locations along
the abandoned sewer line that cannot be re-forested. As detailed in the attached
photos, existing structures (e.g. driveways, carports, flower beds) limit our ability to
restore the buffers. Additionally, there are also areas within the easement that have not
been maintained, and therefore, have become densely vegetated (see photos). We do
not believe that these areas will benefit form additional plantings, the City will insure
that these sections of the abandoned easement remain undisturbed. Photos of the
restoration sites are also included with the attachments.
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. NA
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.
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 an after-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 impact analysis in 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: This

proiect involves the replacement of an existing sewer line The surrounding areas are established
neighborhoods: therefore, we do not believe that this project will have a negative im acp ton
downstream water quality.
XV. Other Circumstances (Optional):
It is the applicant's responsibility to submit the application sufficiently in advance of desired construction dates to
allow processing time for these permits. However, an applicant may choose to list constraints associated with
construction or sequencing that may impose limits on work schedules (e.g., draw-down schedules for lakes, dates
associated with Endangered and Threatened Species, accessibility problems, or other issues outside of the applicant's
control).
