New Hope/The Oaks Apartments Sanitary Sewer Repair
PCN Application
Dewberry Project No. 50005267
Dear Ms. Karoly:
Enclosed are seven copies of a Pre-Construction Notification (PCN) Application Form, site location map,
details, and a permit processing fee of $240, for the project: New Hope/The Oaks Apartments Sanitary
Sewer Repair.
The New Hope/The Oaks Apartments Sanitary Sewer Repair project is planned by the City of Raleigh
within a sanitary sewer easement along an intermittent unnamed tributary of Beaverdam Creek where
streambank erosion threatens to destabilize the adjacent sanitary sewer and manholes.
The project will include placement of compacted fill, boulder material, and rip rap to replicate the
location of the uneroded streambank and utilization of a "step-down"/energy dissipation detail at the
outfalls of two swales into the unnamed tributary. Material will be placed with dump trucks and
trackhoes (i.e. conventional construction equipment) and the site will be seeded and mulched upon
completion of the work.
Please call with any questions regarding this permit application.
Sincerely,
Dewbe & Davis, Inc.

III. Project Information
Attach a vicinity map clearly showing the location of the property with respect to local
landmarks such as towns, rivers, and roads. Also provide a detailed site plan showing property
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.

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.
Updated 11/1/2005
Page 3 of 9
Provide a written description of the proposed impacts: This project area is at an unnamed
tributary of Beaverdam Creek. Approximately 120 linear feet of streambank will be
disturbed during stabilization ofI eroding areas. The streambank is less than 1.0 feet wide for
a total disturbed area of approxirnately 0.028 acres. The outfalls of two drainage swales into
the intermittent unnamed tributary will be stabilized and constitute a disturbance in Zone 1 of
the Neuse River buffer. It is expected that this disturbance will be approximately 230 square
feet in each. location for a total disturbance in Zone 1. of 460 square feet.

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. Impact is necessitated by the
failure of an eroding streambank in close proximity to the sanitary sewer system. Effort will be
made to minimize impact by limiting the work area, and completing the work (including re-
stabilization of streambanks and seeding and mulching of vegetated areas) during three (3)
consecutive days with no precipitation.
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
htip://li2o.enr.state.nc.us/ncwettands/strmgide.htni1.
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.
Updated 11/1/2005

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/wip/index.htm. If use of the NCEEP is proposed, please
check the appropriate box on page five and provide the following information:

Amount of buffer mitigation requested (square feet): N/A
Amount of Riparian wetland mitigation requested (acres): N/A
Amount of Non-riparian wetland mitigation requested (acres): N/A
Amount of Coastal wetland mitigation requested (acres): N/A

IX. 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.
