Re: Town of Mooresville - Mount Mourne Gravity Outfall

Corps Action ID # SAW -2012-00538
DWR Project #12-0198
Cathy/Jennifer:
The attached Pre -Construction Notification (PCN) is being submitted on behalf of The
Town of Mooresville (Town) to install a 2.6 -mile gravity outfall sewer line that will
connect to an existing gravity outfall sewer line that parallels West Branch Rocky River.
There is approximately 761 linear feet of stream, 0.8569 acres of wetlands, and no
open water within the project area. The Town is seeking authorization under
nationwide permit 12 for 736 linear feet of temporary stream impacts including 160
linear feet for temporary culverts, 351 linear feet for erosion control matting, and 225
linear feet for rock silt dams to pump around stream flow during construction. The
temporary trenching impacts are included in the 736 linear feet of overall temporary
stream impacts. Wetland impacts consist of 0.090 acres of permanent impacts from
wetland conversion from forested to herbaceous and 0.767 acres of temporary
construction impacts. A detailed accounting of stream and wetland impacts is on the
attached impact table.
The construction of the sewer line will consist of an open cut trench at all locations
except for the crossings at West Branch Rocky River and Midway Lake Road. These
two locations will be directionally bored. No permanent culverts are being requested
for maintenance access. The temporary impacts are necessary for access, installation,
and sediment/erosion control during construction and stabilization once construction is
completed.
While there is 0.090 acre of permanent conversion of forested wetlands to emergent
herbaceous wetlands proposed along the permanent easement temporary impacts to

VIRONMENTAL
wetlands have been minimized through routing alternatives and design revisions. The
original design specified a 30' maintenance corridor at stream and wetland crossings
but through discussions with the design team and Town the maintenance corridor has
been reduced to 15' at the jurisdictional crossings. The topsoil at wetland crossings will
be stock piled and re -used to establish the existing contours once construction is
completed. A wetland restoration plan for the temporary impacts and conversion at
wetland crossings is enclosed.
The Town will not be using State or Federal bond funding, but they will be using local
fee monies to fund the project. Atlas coordinated with Mrs. Hannah Headrick, DWQ
SEPA, during the early stages of this project concerning the potential requirement of an
Environmental Assessment (EA). This project does not meet the general or specific
criteria for an EA per 15A NCAC 01C .0408 Minor Construction Activities which was
verified by Mrs. Headrick. This is a gravity line that is less than 3 miles in length.
The construction easement for this project is 55' wide and the permanent easement is
30' wide (15' wide at stream and wetland crossings). To address the necessity for a 55'
wide construction easement the design team and Town provided the following
information. The geotechnical investigation for the project recommended 3:1 side
slopes for the open trench which may not be possible in all locations due to the
construction easement width. The contractor will more than likely employ a trench box
due to the side slope recommendations and the depth of installation. The reaches of
deeper pipeline (18' deep in some locations) will more than likely require double staking
of trench boxes to adhere to a 55' construction corridor. The construction easement
will consist of the open trench, the pipe string, the spoil pile (in wetlands, not streams),
the equipment access road, and erosion control devices (in streams). Where possible,
within wetlands, the spoil will be placed in high ground as opposed to adjacent wetland
areas. The spoil pile width may be approximately 20' wide depending on the depth of
the sewer line. The depth of the sewer line from ground level ranges from 7' to 18'
deep.
The slope of the sewer line ranges from 0.17% to 1% and thirteen drop manholes are
required to maintain the pipeline slopes given the significant change in topography
along the 2.6 miles. Lying of the pipe outside of the trench typically takes
approximately 5 linear feet and the access road for equipment will be approximately 10
linear feet (20' of stream culvert is required for the 10' wide access road for shoulders).
The temporary sediment and erosion control measures within streams will require
approximately 15' which doesn't leave much room for the open trench itself within a 55'
construction corridor.

The construction easement is shown to be located within 10' of the UT to WBRR along
700 linear feet at an existing farm just upstream of the Midway Lake Road culverted
crossing. The placement of the easement at this reach is being dictated by the location
of an existing barn and pond at the farm. The sewer line will be installed 26' to 28'
from the top of bank of the UT to WBRR. The Town has no intentions of disturbing
land that will create unstable banks along the UT along this reach of stream, but the
Town's construction easement does extend to the top of bank. There are also three
different power lines along this reach that are dictating the placement of easements as
well. There is a Duke Power transmission line, an Energy United line, and a residential
line.
This permit application package contains the following enclosures: agent authorization
form, pre -construction notification, cultural resources and NHP "no effect letters",

Prepared by:
Town of Mooresville
Mount Mourne Gravity Outfall
Wetland Restoration Plan
February 16, 2012
x

Introduction
All of the wetland impacts requested in this permit application are temporary in
nature to allow for the construction of a 24" to 30" gravity sewer line. Some
wetland areas are considered forested by the Corps and these areas will be
converted to emergent herbaceous wetlands within the permanent easement.
There will be 0.089 acres of wetlands converted from forested to non -forested
wetlands even though forest land will continue to surround these wetlands as it
does currently. The conversion of these wetland areas within the 15' wide
permanent maintenance easement is being mitigated through the maintenance
practices that the Town have adopted that are discussed below. The temporary
construction easement is 55' wide.
Methods
This plan proposes restoration methods to be used to restore the requested
temporary impacts to wetlands along the Mount Mourne Gravity Outfall. The
sewer line will be installed in an open cut trench. The topography along the
alignment was surveyed and mapped to 2' accuracy during the design phase of
the project. If it is determined to be necessary, additional topography within the
wetland areas will be collected prior to construction.
The topsoil within the wetland areas will be stock piled separately from the
subsoil. Excavated materials within wetlands will be placed on fabric whenever
possible to minimize impacts. The subsoil will be backfilled and compacted
before the topsoil is replaced and graded to pre -construction contours. These
contours will be re-established within the wetland areas by comparing them to
the pre -construction contours that have been surveyed. The graded contours
will be shaped to match the surrounding natural contours that were not
disturbed during construction.
The topsoil will contain a viable seed mixture of wetland vegetation that will re-
establish itself once restoration is complete. However, if necessary, a wetland
seed mix will be broadcast in wetland areas that do not re -vegetate naturally
with wetland plants. Only native species of woody and herbaceous wetland
plants will be used for restoration. Stumps within the disturbed wetland areas
will be grubbed only as necessary for installation of the sewer line while
remaining stumps will be cut off at ground level.
Goals
The area outside of the permanent maintenance easement (20' on either side of
the maintenance corridor) will be restored to forested wetlands through the re-
establishment of volunteer woody vegetation and planting of live stakes. The
woody vegetation within the wetlands within the maintenance corridor will be

hand trimmed as opposed to mowed which will prevent the wetland soils from
becoming compacted and will also prevent herbaceous vegetation from being
impacted by a tractor and mower. The maintenance practice should also allow
for the continual existence of a more natural wetland habitat than compacted
soils that tend to create flooded wetlands that potentially lack significant
herbaceous vegetation.
The majority of the forested wetland areas will be temporarily impacted and
converted along the fringe of the wetland. Only three of these wetlands will be
impacted through the center of the wetland area. None of these three wetland
areas have large trees growing in them. They all have a shrub layer but no tree
layer. These wetlands are 0.03, 0.087, and 0.144 acres in size. The conversion
width is the maintenance corridor width of 15' and all of these wetlands will
continue to be shaded by the surrounding much larger trees than what occurs
within the wetlands themselves.
Hydrology through the wetland areas will be restored as well as part of this
restoration plan. Some of the wetland areas contain drainages within them
which will be restored to pre -construction grade. If excess subsoil remains once
restoration is complete it will be disposed of in a high ground area along the
alignment.
Town Information
The Town of Mooresville's Water and Sewer Department is responsible for the
maintenance along utility lines which are under the jurisdiction of the Town. The
Town typically mows the rights-of-way at least once a year but sometimes twice
a year with a medium sized tractor. The Department tries not to mow during the
wet season or after heavy rainfalls. The Town will provide the contractors who
bid on the construction of this sewer line with a copy of the permit application as
well as the 404 and 401, if requested.

Dear Ms. Robertson:
Office of Archives and History
Division of Historical Resources
David Brook, Director
On August 8, 2011, we received notification from the State Clearinghouse concerning the above project.
There are no known archaeological sites within the proposed project area. Based on our knowledge of the
area, it is unlikely that any archaeological resources that may be eligible for inclusion in the National Register of
Historic Places will be affected by the project. We, therefore, recommend that no archaeological investigation
be conducted in connection with this project.
Based on the submitted map, the Southern Alternate Outfall Route may potentially have an adverse effect on
historic properties as the route appears to traverse two properties listed in the National Register of Historic
Places, the George Houston House (ID 0026) and Wood Lawn (ID 0041). If this route is pursued, please
forward a site plan showing the existing and proposed rights-of-way and/or easements, property lines, and
existing landscaping (indicating any landscaping proposed for removal or replacement).
We are aware of no historic resources that would be affected by the Proposed Route or the Northern Alternate
Route. We have no comments on either of these routes.
The above comments are made pursuant to Section 106 of the National Historic Preservation Act and the
Advisory Council on Historic Preservation's Regulations for Compliance with Section 106 codified at 36 CFR
Part 800.
Thank you for your cooperation and consideration. If you have questions concerning the above comment,
please contact Renee Gledhill -Earley, environmental review coordinator, at 919-807-6579. In all future
communication concerning this project, please cite the above -referenced tracking number.
Sincerely,

FROM: Ron Linville, Regional Coordinator
Habitat Conservation Program
DATE: August 18, 2011
SUBJECT: State Clearinghouse Project No. 120027, Mount Mourne [Sewer] Gravity Outfall, Iredell
County
This correspondence responds to a request by you for our review and comments for the Environmental
Scoping (ES) for the referenced sewer improvement. Biologists with the North Carolina Wildlife
Resources Commission (NCWRC) are familiar with habitat values in the area. The NCWRC is
authorized to comment and make recommendations which relate to the impacts of this projoct on fish xnd
wildlife pursuant to Clean Water Act of 1977,.North Carolina Environmental Policy Act, US National
Environmental Policy Act, Endangered Species Act (1:6 U. S. C. 1531-1543; 97 Stat 884), the Fish and
Wildlife Coordination Act (48 Stat. 401, as amended, 16 U.S.C. 661-6674) and/or Federal License of
Water Resource Project Act (Federal Power Act -16 U.S.C. 791a et seq.) as applicable.
The cover memo for the project indicates that the project will be approximately 2.6 miles of outfall
primarily located along tritest Branch Rocky River. The submittal does not provide specific information
about the capacity of the outfall or indicate whether or not the project will serve existing communities or
serve to expand municipal service areas and increase annexations.
Our in office review of the project area found that the Bog turtle, GI}ptemys muhtenbergii (NCT, FT S/A)
has been known from the area south of the terminal end of the project near the Rocky River.
Additionally, the Star -nosed mole, Condylura cristata (NCSC) is known from southwest of the sewer.
Both of these species live in and depend on moist habitats, creeks and wetlands. The mole is known to
inhabit the banks of streams and open water impoundments. The mole's habitats include lands near
coniferous and deciduous forests, wet meadows and wetland marsh environs which could support the Bog
turtle if shallow, muddy and without dense woody vegetation.
Based on our review, we recommend that pro}oct proponents, including contractors and construction
workers become familiar with the characteristics of the Bog turtle and the Star -nosed mole. Should any
individual animals be observed, they should tzc protected from harsh and this office contacted to
determine how to restore the animal to its habitat or other disposition as appropriate. In addition, sewer
lines should not be located near streams and wetlands Instead public utilities should be placed along the

edge of the floodplain This placement will also protect the utility from eroding and meandering stream
ecosystems which will save maintenance costs. In addition, this office routinely recommends the
following for land use planning to mitigate for developmental impacts that may follow the provision of
sewer:
i. Prior to tree removal and site clearing activities on a proposed development site and prior to local
site planning and zoning approvals, all jurisdictional waters and wetlands should be
professionally delineated pursuant too the Clean Water Act (CWA) using US Army Corps of
Engineers (COE) and NC Division of Water Quality (DWQ) criteria. This should be
accomplished as part of the developer's due diligence and site evaluation process. CWA permits
arc required for culverts for driveways, parking lots, road crossings as well as utility (including
sewer) lines that impact waters of the 'United States. Should impacts occur to jurisdictional
waters or wetlands, stcumwater management should be provided. Agricultural or forestry
exemptions must not be allowed when the ultimate use of a property will be a development.
2. Jurisdictional streams, wetlands and higbly erodible areas and associated stream buffers should be
maintained or restored as contiguous undisturbed forested areas. In watersheds supporting listed
aquatic species, stream buffers should be 100' for intermittent channels and 200' for perennial
channels. In watersheds without listed species, time buffers should be 50' and 100' respectively.
Buffers should be permanently pry as common conservation areas instead of subdivided.
Where practicable, impacted streams should be relocated using state -of -thea -art natural channel
design and native vegetation instead of piping the streams as is typically done. Local authorities
should keep sewer line& water lines. and other utilities out of riparian zones and buffers.
Placement should occur along the floodplain fringe.
3. For stream crossings, culverts 48" diameter or larger should be buried a foot into the streambed.
Culverts less than 48" diameter should be buried to a depth equal to or greater than 20% their size
to allow for aquatic life passage These me &%wements must be based on natural thalweg depths.
4. Stormwater managemert should maintain, to the extent .possible, pre development hydrographic
conditions. Stormwater control measures should be implemented before impervious surfaces
reach 10% for most watersheds and 6 % for watersheds with listed species present downstream.
Low Impact Development (LTD) techniques are encouraged for all new developments and
redevelopment efforts. If impervious area exceeds ten (10) percent, stormwatcr management
strategies that maintain or restore pre development hydrograph conditions are recommended.
Information on Low Impact Development (LID) practices and measures can be found at
www.lowimpactdevelopn t.ore, ht!p://www.;Meovlowo-w/nns/lid/lidqptlmff and
bM://www.stonnwatcrcer[teratil. Maintenance of the pre -disturbance hydrograph is needed to
reduce downstream channel destabilization, flooding and streambank erosion. Stormwater
management ponds should be forested (excluding dams) with native plants to reduce thermal
impacts to waters.
5. Fill in Federal Emergency Management Agency designated floodplain as well as CWA
jurisdictional water floodplain should be prohibited or no net loss strategies should be used
This is an essential and important maintenance component of -stormwater management. .Entire
floodplain areas should be protected as undisturbed forested areas to benefit local air and water
quality as well as provide habitat values.
6. Sediment and erosion controls should me# NC Division of Water Quality requirements for the
classification of watersheds. Preferably, sediment and erosion control measures should adhere to
the design standards for sensitive watersheds (15A NCAC 4B.0124).
7. Project propos and local government officials should visit our website at
httl3l/www.nc,mildlife.gr_q�pgL7 Wildlif6peciesCon!pg7c3 iuMpts.pdf to learn more about
historical or incremental diminishment of habitats associated %rith increased imperviousness.
Mitigative measures can significantly reduce these negative impacts and, in some instances,

Mount Mourne Gravity Outfall Page 3 August 18, 2011
restore some of those lost or dnninished environs. Project proponents should visit Audubon
International at httu://v,- w.audubonin ernational.ora and the National Wildlife Federation at
hxM/www.uwf,pa to learn mom about wildlife friendly certifications and standards. Meeting
these or similar prolective criteria should be a preferred goal for development.
If the sower improvements will have the capacity to open up a much larger area(s) for annexation and
development, an Environmental Assessment (EA) should be provided that addresses the issues indicated
above as well as the information requested in the attachments below. If the project is essentially limited
to serving existing development and little more, an Environmental Review (ER) at the community level
may suffice providing the measures above are implemented as applicable and practicable (previously
recommended for the Presbyterian Pump Station, West Branch Gravity Outfall).
Thank you for the opportunity to review and comment on this project. If you have any questions

General Guidelines for Environmental Reviews
Due to staff limitations, this standardimd response was developed. Although some of the
iufnrma .on, requests mid cornrim is may not be applicable to certain projects, these guidelines
should facilitate preparation of fish and wildlife Environmental Assessrnents (EA) or
Environmental Impact Statements (EIS). In addition to addressing site specific cbmems, the
environmental document should include a detailed assessment of existing natural resources
within the areas of potential development and should discuss the potential of mitigating
development impacts to wetlands, streams and high quality floodplain and upland habitats. To
provide a meaningful review of the EA or EIS prepared for the project(s) secondary and
cumulative impacts, we request that project consultants and sponsors provide the following
information:
1) Project proponents should provide equal attention to direct project impacts and indirect
impacts that the project will precipitate.
2) Description of waters and/or wetlands affected by the project(s). Description of fishery
and wildlife resources within the project area, including a listing of federally or state
designated threatened, endangered, or special concern animal and plant species in the
project area and any areas that may be impacted by secondary or cumulative impacts
within the affected sub-basin(s). A lisft of designated species can be developed
through consultation with the North Carolina Natural Heritage urogram or the US Fists
and Wildlife Service.
3) Project map identifying wetlands and intermittent as well as perennial streams in the area
Identification of wetlands may be accomplished through coordination with the U.S. Army
Corps of Engineers, If the Corps is not consulted, the person delineating wetlands should
be identified and criteria listed.
4) Description of activities that will occur within streams and wetlands, such as fill or
channel alteration. Acreage of wetlands impacted and linear feet of stream channels to be
relocated, channeled, culverted or disturbed by some other means by ahm ative project
designs should be listed.
5) Description of project site and non -wetland vegetative communities.
b) Description and cover type map showing acreage of upland wildlife habitat impacted by
the project.
7) Discuss the extent to which the project(s) will result in loss, degradation, or
fragmentation of wildlife habitat.
8) Disc= any measures proposed to avoid or reduce impacts of the project or to mitigate
for unavoidable habitat losses.

Mount Moiaae Gravity Outfall Page 5 August 18, 2011
9) Discuss the cumulative impacts of secondary development facilitated by the -proposed
ut0ity improvements and any interre1wed infrashucture projects, especially the impacts to
water quality and habitat in the impacted watershed(s). Such discussion should weigh the
economic benefits of such growtb against the costs of associated environmental
deegradatiOu
(a) incbxle specific measures that will be used to address stormwater at the source.
Include specific requirements for both residential and industrial developments and BWs
that will be required.
(b) Include specific measures that will be used to protect stream corridors, riparian .habitat
and a minimum of a 104 -year floodplain. Since all streams have floodplain, it is
important to avoid fail in active fltodplain areas, not just the 100 -year floodplain.
(c) Include specific nmsmes that will be implemented to promote water conservation
and wastewater reuse.
(d) Inebide a discussion of any other local ordinances or programs (e.g., industrial
pretreatment, infiltration and inflow management, farmland preservation, habitat
restoration1preservation, and recycling) that will mitigate the impacts of development.
10) Discuss the use of any mitigation, preservation, deed restrictions, and conservation plans
and management objectives. These should include detailed site descriptions and maps.
A determination concerning which agency or entity (e.g. land conservancy) will own and
manage the easements or property should be included.
Note: A list of document preparers should be provided that provides each individuars
professional background and qualifications.

Utility Line and Saver Lice Avoidance and Minimization Recommendations
Meaures to avoid or minimize impacts to sensitive resovrces, including wetlands, should be
implemented during all phases of construction associated with the area. Where iwpacts to
wetlands {and waters) are unavoidable, we will recommend mitigation of the losses. In addition
to providing wildlife babitat, wetland areas perform the important fimrtions of flood control and
water quality protection. Whenever possible, utility lines should be plaoed along existing right-
of-ways along roads and previously impacted conidors. Pumping may be economically feasible
where direct or secondary impacts can be avoided in sensitive habitats. To avoid or minimize
stream and wetland impacts during construction of utility tines, we oflaer the following non -
prioritized general recommendations that should be incorporated into project pians:
1) Construction corridors should be no wider than absolutely necessary. The 401
certification for Nationwide 12 stipulates that wetland construction corridors are not to
exceed 40 feet and permanent maintained corridors are not to exceed 10 feet except at
access points. The NC Division of Water Quality's 441 Certification for utility lines
should be followed specifically for all jurisdictional impacts. Where crossings are
necessary, sewer Imes should cross streams at right angles to minimize impacts to
riparian areas. Restored screams and stream banks should be planted with autochthonous
(native) plants like silky dogwood, rhododendron, dog hobble, red maple, sik willow,
tag alder, black willow, sycamore, river birch, or other dative woody species. Riprap
may be used to stabilize the bank in the area of the ordinary high waxer stage and
vegetation (bioengineering) should be used above this stage. Aquatic life passage must
not be hindered during low flows upon project completion. Directional born is the
Wferred method of crossing jurisdictional waters and wetlands.
3) Utility lines crossing streams should be buried in the stream bottom or attached to
existing bridges to maintain fish movement upstream and downstream and prevent debris
from collecting at the pipe and causing a hydrologic change. We do not recommend
installing priers in a stream chamiel to support a sewer line.
4) If concrete will be used, work must be accomplished so that wet concrete does not
contact streain water. This will lessen the chance of altering the stream's water chemistry
and caning .a. fish kill.
5) An undisturbed buffer acne should be left between streams and all oonatrucdon We
prefer a buffer zone of at least 100 feet to control sedimentation into. streams, provide
shade, and maintain a travel corridor for wildlife. Buffers should also be left along
intermittent drains or streams. To the maximum extent practicable, utility lines should be
located on the edge of floodplain and away from riparian areas, wetlands and screams.
6) TemporariEty disturbed wetlands should be reseeded with annual small grains appropriate
for the season (e.g. annual oats, millet, or wheat) and be allowed to revert to native
natural wetland vegetation.

Mount Mrnane Gravity Outfall Page 7 August 18, 2011
7) A portion of the upland right-of-way (minimum of one acre) should be planted with
native warm season grasses ladmo clover, and/or partridge pea to provide food and
additional habitat mr wildlife. Autoehthguous punts sbDuld be used to the maxinwm
extent„prmcticsbk. R.outarly rg_own agricultural annual iilauts hle oats, wheat or barley
are gootab1e for teWma nursery cover.
8) Slash and/or large trees available form corridor construction through forested and stream
corridors should be placed along the permanent right-of-way in the form of brush piles
and downed logs to provide cover and nesting habitat for wildlife.
9) If necessary, ROW areas should be mowed not more than once every two (2) to flaee (3)
years. Mowing should occur between said -March and . mid-Aprd to avoid disturbing
wildlife utilizing the project corridor during the critical stages of nesting and rearing as
well as to ensure winter cover.
10) Stringent erosion control measures should be implemented where soil is disturbed and
maintained until project completion_
11) Temporary or permanent herbaceous vegetation should be planted on all bare soil within
five (5) to ten (10) days of ground disturbing activities to provide long-term erosion
control. We prefer a "seed as you go" strategy rather than allowing a large area to remain
bare.
12) To repeat an important point, MD utilities should be located away from stream banks acid
riparian buffer zones Running these along floodplain edges and contours should be
accomplished whenever posslNe.
