Re: Fre-Construction Notification (PCN) Application Form-
- Kings Bluff Raw Water Intake Canal Dredging Project '
Ci#y of Wilmington. Raw Water Intake Pumping Station .~ _ ~`r.,
Bladen County
Dear Ms. Hair:
The City of Wilmington has engaged HDR Engineering, Inc. of the Carolinas to develop plans and
guidelines for maintenance dredging activities along the man-made canal at the Kings Bluff raw water
intake pumping station: The project will include:
• Removal of accumulated silt and sediment within the man-made canal and at~the confluence with
the, Cape Fear River.
• ..Placement of the spoil material on the canal banks.
• Crrading of the spoil to a uniform depth along the-banks of the canal.
• Stabilization of the graded spoil using erosion control techniques.
As a result of the proposed maintenance dredging activity, the attached PCN has been developed and is
being submitted. This man-made. canal is proposed to be dredged to return the canal to the original
configuration. This .canal facilixates the intake.. of water from the Cape Fear River to the City of
Wilmington's raw water pumping station: Any impacts .should be minor and temporary. The
following material is being provided. in accordance with the PCN instructions:

local stormwater requirement, etc.):
Current land use in the vicinity of the pond:
Size of watershed draining to pond:
VII. Impact Justification (Avoidance and Minimization)
Expected pond surface area:
Specifically describe measures taken to avoid the proposed impacts. It maybe 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. Dredging by excavation is the
best means to allow the intake of the raw water pumping station to operate as designed. Erosion
control measures will be employed to minimize any water quality effects of this activity.
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.
Updated 11/1/2005
Page 9 of 12

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
httt~://h2o.enr.state.nc.us/ncwetlands/strmgide html.
