Re: Timberlake 2a Joint Driveway Crossing
Dear Staff,
Enclosed is the PCN request for an additional 31 feet of stream channel impacts as a
"shared/joint" driveway for two single-family homes in the existing subdivision of
Timberlake in Johnston County. The owner of the subdivision has completed the single
road crossing of 110 feet for the 5 previous phases. The proposed 31 ft. joint driveway
impact will keep the cumulative impacts for the entire subdivision below the 150 ft.
mitigation threshold. Included is the previous request for more information on the
original submission for 4 driveways. This request has been modified to one single "joint
driveway" crossing per our consultation with DWQ staff. Please note that the map also
reflects only 2 lots, not 4, as previously proposed.
If you have any questions or comments, please contact us.
Thank you. Sincerely,
1 ..

community open space with deed restrictions on recorded lots, Driveway crossing proposed to
avoid additional major road crossing and multiple driveway crossings
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
Page 5 of 8
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/stn-ngide.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.
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
