10. Describe the overall project in detail, including the type of equipment to be used:
Placement of an approximately 8 ft. high temporary fabric weir across Drowning Creek to
facilitate water extraction by 2 existing intakes from Drowning Creek for the Town of
Southern Pines water supply. A 30 inch PVC wipe was placed under the weir so that all flow
was not blocked. We pose to replace the fabric weir with a 3-4 foot high sheet-pile weir
within the banks of the creek.
11. Explain the purpose of the proposed work: To provide the Town of Southern Pines with
drinking water in a drought emergency situation. In August the creek level fell below the
level of the intake screens at the water plant intake site. The combination of extremely low
flows, the height of the intake structures and insufficient storage capacity led to mandatory
water use restrictions in August. Average water withdrawals were 5 mgd eak 6 mgd) og ins
into August (the permitted withdrawal is 8 mid). B~gust withdrawals were down to 3.0
mid and a water emergency was declared. The fabric weir was put in place on 14 August
We propose to replace the existing weir with asheet-pile weir within the existing channel
approximately 3-4 feet high. This run-of--river weir will create a pool at the intake structures
There will be no overbank flooding.
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 USAGE 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certifications were issued or withdrawn.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
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.
Dr. J.H. Caster III met with Mr. Henry Wicker (ACOE) onsite on 10-9-02 to discuss future
construction of a permanent weir and an offline holding~ond. Mr. Wicker issued verbally an
after-the-fact permit for a temporary weir for 1 year.
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.
An application will be submitted for the construction of a permanent 3-4 foot high sheet-pile
weir and the construction of a 25 acre upland holding~pond.
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. The applicant must also
provide justification for these impacts in Section VII below. All proposed impacts, permanent
Page 7 of 13

and temporary, must be listed herein, and must be clearly identifiable on an accompanying site
plan. All wetlands and waters, and all streams (intermittent and perennial) must 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: A fabric weir was installed
approximately 3 feet above bank height across the creek, with a 30 inch oven PVC nine at the
it in place. As a
result, water has backed up approximately 100 feet upstream, and water levels have risen
approximately 4 feet above downstream levels. We propose to replace the fabric weir with a
sheet-pile weir a proximately 3-4 ft. high, within the existing channel. This will create a
pool at the intake structure without causing overbank flooding. A 30 inch PVC pipe will go
through the sheet metal to ensure constant flow Water is expected to back up approximately
75 feet as a result of the sheet-pile weir. Rip-rap will be spread 20 feet downstream of the
weir to diffuse flow.

dams (separately list impacts due to both structure and flooding), relocation (include linear feet before and after, and net loss/gain),
Page 8 of 13

stabilization activities (cement wall, rip-rap, crib wall, gabions, etc.), excavation, ditching/straightening, etc. If stream relocation is
proposed, plans and profiles showing the linear footprint for both the original and relocated streams must be included.
** Stream names can be found on USGS topographic maps. If a stream has no name, list as UT (unnamed tributary) to the nearest
downstream named stream into which it flows. USGS maps are available through the USGS at 1-800-358-9616, or online at
www.us~s.~ov. Several Internet sites also allow direct download and printing of USGS maps (e.g., www.topozone.com,
~~~ww.mapcLuest.com, etc.).

* List each impact separately and identify temporary impacts. Impacts include, but are not limited to: fill, excavation, dredging,
flooding, drainage, bulkheads, etc.
5. Pond Creation
If construction of a pond is proposed, associated wetland and stream impacts should be
included above in the wetland and stream impact sections. Also, the proposed pond should
be described here and illustrated on any maps included with this application.
Pond to be created in (check all that apply): ^ uplands ^ stream ^ wetlands
Describe the method of construction (e.g., dam/embankment, excavation, installation of
draw-down valve or spillway, etc.): N/A
Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond,
local stormwater requirement, etc.):
Size of watershed draining to pond: Expected pond surface area:
VII. Impact Justification (Avoidance and Minimization)
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.
The existinsr weir is annroximately 4 ft. over the adiacent banks of Drowning Creek,
proximately 8 feet high. The 30 inch pipe under the weir allows water to flow continuously
under the weir. A ape will also be placed under the proposed sheet-pile weir. Twent fy eet of
rip-rap will be spread in the channel to diffuse water comin tg hrough the PVC pipe and to
prevent scour of the creekbed from flow over the weir. The Town is not proposin>; to increase
the level of intake permitted (8 mgd), just to take measures so that a sufficient water level at the
intake structures is attainable in the case of severe drought.

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 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 determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that maybe 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://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,
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.
None proposed.
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 determine availability and to request written approval of mitigation prior
to submittal of a PCN. For additional information regarding the application process for the
NCWRP, check the NCWRP website at http://h2o.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
