RE: Request forNWP 12, 401-Certification, and Neuse Buffer Compliance
Carramore Sewer Extension
Cary, Wake County, North Carolina

~(g@(gnw@~

FEB 2 3 200S

Dear Ms. Karoly and Mr. Tugwell: "") '11 ':-v
DE"Q - w;\rt:!, C~', ,,'
V:ETWiDS N~D STOi\i.I'JiAIt:K totiAllCH
On behalf ofMDC Homes (easement holder), we hereby request authorization from the
US Army Corps of Engineers (USACE) to use Nationwide Permit 12 to cover impacts to
wetlands and a perennial stream channel resulting from the installation "of a proposed
sanitary sewer line. We also request written concurrence from the North Carolina
Division of Water Quality (DWQ) that the project complies with the associated water
quality certification and the Neuse Buffer Rules for proposed impacts. A Pre-
construction Notification Application (PCN) is attached, which includes an agent
authorization form.

Location
The proposed sewer corridor is located immediately west of Davis Drive (SR 1613) and
approximately 2,200 feet north from the intersection of Davis Drive and High House
Road (SR 1615) in Cary, NC. Please see the attached USGS site vicinity map.

Proiect History
The Carramore subdivision will be served by the proposed sanitary sewer line and was
issued pennits from the USACE and the NC DWQ. The USACE Action ID # was
200421185, and the DWQ Project Number was 04-0~26.

Impact Justi fication
The applicant settled on the proposed sanitary sewer corridor to minimize impacts to
existing large trees and the perennial stream. "The most direct route was an existing
easement, which was discarded as an option because it would have run along the bank of

the chatmel or through the stream for more than 50 feet, which is currently prohibited.
The proposed sanitary sewer line could not be moved to the east because of existing
houses and/or related structures, and could not be moved further west for the same
reason. Additional constraints include large trees and landscaped areas that also include
large trees. In some cases, the roots of the large trees provide bank stabilization, and
removing them would destabilize the stream banks. The proposed plan, in an effort to
minimize impacts to existing vegetation, resulted in larger than normal buffer impacts.

Mitigation
Due to the temporary nature of the proposed impacts, required stream mitigation is not
expected from the USACE or the NC DWQ. However, NC DWQ's riparian buffer rules
require mitigation for buffer impacts in Zone 1 for non-perpendicular ,crossings or
impacts parallel to the stream channel. Mitigation for the 2,072 square feet of Zone 1
impacted by the proposed sanitary sewer corridor is requested from NC EEP, as in-lieu
payment for 6,216 square feet at the current 3: 1 mitigation ratio for Zone 1 buffer
impacts.

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.
The applicant settled on the proposed sanitary sewer corridor to minimize impacts to
existing large trees and the perennial stream. The most direct route was an existing easement.
which was discarded as an option because it would have run along the hank of the channel or
through the stream for more than 50 feet. which is currently prohibited. The proposed sanitary
sewer line could not be moved to the cast because of existing houses and/or related structures.
and could not he moved further west for the same reason. Additional constraints include large
trees and landscaped areas that also include large trees. In some cases. the roots of the large trees
provide bank stabilization. and removing them would destabilize the stream banks. The
proposed plan. in an effort to minimize impacts to existing vegetation. resulted in larger than
,normal buffer impacts.

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
Pennits, published in the Federal Register on March 9, 2000, 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 detennining 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 NCWRP 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://h20.enr.state.nc. us/ncwetlands/stnngide.html.

1. Provide a brief description of the proposed mitigation plan. The description should provide
as much infonnation 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.
Temporary stream impacts generally do not require mitigation by the USACE or NC
DWQ. Buffer impacts to Zone 1 totaling 2.072 square feet are allowable with mitigation.
The applicant proposes payment to NC EEP for 6.216 square feet of buffer in Zone 1.

2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP). Please note it is the applicant's responsibility to contact the NCWRP at
[phone] to detennine availability and to request written approval of mitigation prior
to submittal of a PCN. For additional infonnation regarding the application process for the
NCWRP, check the NCWRP website at http://h20.enr.state.nc.us/wrp/index.htm. If use of
the NCWRP is proposed, please check the appropriate box on page three and provide the
following infonnation:

Page 6 0[9

Amount of stream mitigation requested (linear feet): 0 linear feet
Amount of buffer mitigation requested (square feet): 6.216 square feet
Amount of Riparian wetland mitigation requested (acres): 0 acres
Amount of Non-riparian wetland mitigation requested (acres): 0 acres
Amount of Coastal wetland mitigation requested (acres): NA

IX. Environmental Documentation (required by D\VQ)

Does the project involve an expenditure of public (federal/state) funds or the use of public
(federal/state) land?
Yes D No ~

If yes, does the project require preparation of an environmental document pursuant to the
requirements of the National or North Carolina Environmental Policy Act (NEP NSEP A)?
Note: If you are not sure whether a NEP NSEP A document is required, call the SEP A
coordinator at [phone] to review current thresholds for environmental documentation.
Yes D No D

If yes, has the document review been finalized by the State Clearinghouse? If so, please attach a
copy of the NEP A or SEP A final approval letter.
Yes D No D

X. Proposed Impacts on Riparian and \Vatershed Buffers (required by D\VQ)

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.

Will the project impact protected riparian buffers identified within 15A NCAC 2B .0233
(Neuse), 15A NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 2B .0250 (Randleman Rules and
Water Supply Buffer Requirements), or other (please identify )?
Yes ~ No D If you answered "yes", provide the following information:

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
multipliers.

Page 7 of9

Zone* Impact Multiplier Required
(square feet) Mitigation
1 2,072 3 6,216
2 0 1.5 0
Total 2,072 6,216

*

Zone 1 extends out 30 fect perpendicular from near bank of channel; Zone 2 extends an
additional 20 feet from the edge of Zone I.

If buffer mitigation is required, please discuss what type of mitigation is proposed (i.e., Donation
of Property, Conservation Easement, Riparian Buffer Restoration / Enhancement, Preservation or
Payment into the Riparian Buffer Restoration Fund). Please attach all appropriate information as
identified within 15A NCAC 2B .0242 or .0260.
Perpendicular utility crossings are allowable activities under the Neuse River Buffer rules.
Therefore. the applicant only proposes mitigation for locations crossing at a non-perpendicular
angle.

XI. Stormwater (required by DWQ)

Describe impervious acreage (both 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.
The sanitary sewer corridor will not increase impervious acreage at this location.

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.
The proposed sewer line is connecting to a portion of existing Town of Cary sanitary sewer line.

XIII. Violations (required by D\VQ)

Is this site in violation of DWQ Wetland Rules (15A NCAC 2H .0500) or any Buffer Rules?
Yes D No ~

Is this an after-the-fact permit application?
Yes D No ~

XIV. 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
