Enclosed is a revised Nationwide 14 and 401 Water Quality Certification submission for a project referred to
herein as "Warner Lot Access" in Beachside Extension Subdivision in Ocracoke, Hyde County, North
Carolina. As required by USACE, this current alignment further minimizes proposed impacts.
Lot 52 (and 53) had been under contract to be sold, and this was not the preferred route of the access road,
considering economic impacts only. However, this current route minimizes wetland impacts to 0.1 acres as
opposed to 0.35 acres (previously proposed), and, this also achieves the applicants' goal. This continues to
mainly utilize designated rights-of-way (platted with the subdivision 1960) except for the Lot 52 crossing.
There are minor Tar-Pamlico Buffer Zone impacts proposed and I have discussed these proposed impacts
with Kyle Barnes and Amy Chapman. It was indicated to me that this is classified as a road and mitigation is
required for the buffer zone impacts. Mitigation is specified in the PCN Application and the EEP acceptance
letter. Zone 2 impacts would be 785 sq.ft. and Zone 1 would be 33 sq.ft.
This package also responds to the October 23, 2006 Additional Information Request by: (1) providing diffuse
flow provisions by means of vegetative filter strips that we have discussed and described in a November 6,
2006 letter to you. Eddie Valdivieso, P.E. has provided diffuse flow provision worksheets (included herein-
sheets 1-8), and (2) and by providing a signed and notarized Operations and Maintenance Agreement.
Enclosed are 7 copies of the following:
• Site Plan (revision date 11-15-06)
• PCN Application (11-20-06)
• Agent Authorization Letter
• USGS Vicinity Map
• USACE Jurisdictional Determination
• EEP Acceptance Letter
• Letter of Support from Pete and Julie Wiley
• Seeding Schedule

side of the propertv there are areas of coastal wetlands The Section 404 wetlands line has
Updated 11/1/2005
Page 6 of 14

been confirmed on November 13, 2001 by William Walker, USACE. Platwork for re-
confirmation has been submitted to Tom Steffens, USACE on September 16 2006 and
according to Mr. Steffens, a new jurisdictional determination will be issued when the current
USACE moratorium expires. The coastal wetlands line has been delineated in August 2006
by Terry Moore and Steve Trowell of NC Division of Coastal Management. This coastal
wetlands line and associated Tar-Pamlico Buffer Zones (Zone 1 and Zone 2) are depicted on
the site plan. None of the proposed work is within coastal wetlands areas and only a small
area (Zone 1: 33 sq.ft., Zone 2: 785 sq.ft.) is within the Tar-Pamlico Buffer area. The initial
submission, submitted on September 29, 2006, avoided the Tar-Pamlico Buffer area
altogether, however, there was a significant. amount of additional wetlands proposed to be
impacted. According to Amy Chapman, DWQ minor road crossings such as this are
allowable in the Tar-Pamlico Buffer areas with mitigation. This general vicinity of Ocracoke
is comprised of residentially developed and undeveloped residential lots and commercially
developed businesses along NC 12.
10. Describe the overall project in detail, including the type of equipment to be used:
The project involves placement of sand and gravel material through Section 404 freshwater
anon-coastal) wetlands. The proposed wetlands impacts from fill include a 16 ft wide
corridor that will connect existing lands to other existing currently buildable upland lots as
depicted on the site plan. A maximum of 12 inches of material will be placed alon this
alignment. In most places less than 12 inches of lift will be required because while the
impact areas indicated are jurisdictional wetlands the normal water table is at least 6-12
inches below existing grade. There will be three locations where side-by-side 12 inch
diameter traffic rated culverts will be installed to maintain adequate hydrologic connections
of Section 404 wetland areas during_exceptional rain events. Sand will be transported to the
site via dump truck and will be spread and compacted with a bulldozer within the surveyed
road alignment. This material will be compacted and covered with crush and run type gravel
material that will be similarly compacted. During the fill process the edges of the road will
be lined with silt fence.
11. Explain the purpose of the proposed work: The purpose of the project is to improve (with
no paved surfaces) the designated right-of-way access through this portion of Beachside
Extension to provide a safe vehicular access to upland/buildable lots The initial application
submitted on September 29, 2006, proposed to fully utilize the designated right-of-way from
the 1960 platted subdivision. As an avoidance and minimization effort proposed in
coordination with USACE, the applicant now proposes to cross previously buildable Lot 52
in order to minimize impacts to jurisdictional wetlands. The fill material will consist of sand
and gravel only.
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
Updated 11/1/2005

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. A USAGE jurisdictional determination has been issued on 11-13-01
There was a federal and a state permit issued for minor wetlands fill that was never used (all
wetlands have been preserved to date). A prior Nationwide #18 (Action ID 200210886 9-11-
02) and a prior 401 Water Ouality Certification (DWO# 02-1157 10-17-02) had been issued for
a previous owner, Foy Shaw. This work was never initiated and those permits have since
expired. The permits authorized work that is now proposed (crossing Lot 52 to gain access to
buildable lots in the subdivision).
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.
There will be future building permit requests to Hide Countv and there will be on-site se tic
system permit requests to the Hyde Countv Health Department Upland soils in this subdivision
have been found to be suitable by the Health Department
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
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: Impacts include a jurisdictional
Section 404 wetland impact of 0.10 acres. This includes areas that are proposed to be filled
for a vehicular access drive that connects existing uplands to existing uplands The proposed
alignment is within a designated 30 ftright-of--way that was established for Beachside
Extension lot access, except for crossing Lot 52 to minimize total impacts to wetlands This
permit application is submitted on belhalf of Ann Warner but will also provide access to a
buildable lot owned by John Fletcher (Lot 73). Additionally Peter and Julie Wiley (owners
of Lots 81 and 83), will be allowed to utilize the access road that is proposed here to tie into
their two buildable lots in the future. With the currentlv,~uroposed access route the Wile's
could access Lot 83 with a minimal amount of wetlands impacts in comparison with what
they would propose to impact with an access through the designated right-of-way without

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 wetland impacts have been
minimized to the fullest extent possible by limiting the driveway width (toe to toe of fill) to 16 ft
and by crossing currently buildable Lot 52 in combination with utilizing the existin desi ng ated
roadway for this portion of Beachside Extension. This alignment achieves the og al of providing
access to buildable lots owned by the applicant and by others within the subdivision The prior
submission proposed 0.35 ac of wetland impacts compared to the 0 10 ac that is currently
proposed. This is not a joint application, however the project as proposed minimizes future
potential access roadway fill permit re uests b other property owners There is no proposed fill

within an Area of Environmental Concern (AEC) including estuarine AEC and coastal wetlands
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
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/strmgide.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,

RE: Beachside Extension
Residential E_ot Access
As the owner of Lot 81-83 Beachside Extension in Ocracoke, Hyd® County, North
Carolina, 1 support the application for minor impacts to jurisdictional wetlands in the
Nationwide #14 apK~lication being prepared for access to the Wamer lots. We have
received Nationwid~° #14 and 401 Water Quality Certification for Lets 81 and 83,
however, lot access is our current obstacle for achieving our goal of cottage
construction. The proposed road improvements In the application being submitted by
Quible $ Associate~~, P.C. on behalf of Ann Warner would effectively provide access to
our lots as well as tie lots currently owned by Mrs. Wamer. Thore is na other access to
our lots other than 1~he 30 ft wide right~of-way designated as an access road for

The overland flow portion of flow time maybe determined from Figure 8.03a.
The flow time (in minutes) in the channel can be estimated by calculating the
average velocity in feet per minute and dividing the length (in feet) by the
average velocity.
Step 4. Determine the rainfall intensity, frequency, and duration (Figures 8.03b
through 8.03g-source: North Carolina State Highway Commission; Jan.
1973). Select the chart for the locality closest to your location. Enter the
"duration" axis of the chart with the calculated time of concentration, T~. Move
vertically until you intersect the curve of the appropriate design storm, then
move horizontally to read the rainfall intensity factor, i, in inches per hour.
Step 5. Determine peak discharge, Q (ft3/sec), by multiplying the previously
determined factors using the rational formula (Sample Problem 8.03a).

Selecting Channel To calculate the required size of an open channel, assume the design flow is
uniform and does not vary with time. Since actual flow conditions change
Cross-Section throughout the length of a channel, subdivide the channel into design reaches,
Geometry and design each reach to carry the appropriate capacity.
The three most commonly used channel cross-sections are "V"-shaped, par-
abolic, and trapezoidal. Figure 8.OSb gives mathematical formulas for the area,
hydraulic radius and top width of each of these shapes.
