Section B. Project Informationn and Prior Project Histor
133a. Describe the existing condition on the site and the general land use in the vicinity of the
project at the time of the application.
The Mint Hill Athletic Park project is located on the north side of Brief Road in Mint Hill,
Mecklenburg County, North Carolina. The project is located at 35.1876', -80.6028' on the Midland
Quadrangle of the USGS. The Mint Hill Athletic Park Study Area consists of approximately 27.3
acres of land consisting of Mecklenburg County Tax Parcel TD 13 93 0215. The Study Area is gener-
ally bounded by Brief Road to the south, residential properties to the east and west, and undeveloped
land to the north. The site and some of the adjacent property to the north was clear cut timbered in
20 10. The only existing mature tree canopy consisting of mixed medium aged pine and hardwoods
is present along the property line in the very western portion of the site, the remainder of the site is
comprised of mostly herbaceous successional vegetation with scattered species of successional
species of saplings and younger trees that have grown back since being cleared. Two small wetland
areas in the lowest portions of the site are dominated by herbaceous species including Rushes,
Sedges, Cattails, and Goldenrods. There is one small un -named tributary to Clear Creek along the
western property line. This stream is intermittent at its upper reaches and develops into a small
perennial stream further downstream. Aquatic life was not observed in the stream at the time of
inspection but a few crayfish holes were observed.
The entire site is located within the Yadkin -Pee Dee River Basin. The site occurs within the sub -
basin of Clear Creek, along the north side of an unnamed perennial tributary. The nearest named
watercourse is Clear Creek located approximately 3,000 feet downstream of the site (NC Stream
Index 13-17-8-4-1 and Hydrologic Unit Code 03040105) within the headwaters of Rocky River sub -
basin of the Yadkin -Pee Dee Basin. Clear Creek and its tributaries have been identified as Stream
Classification C and are not considered to be Trout Waters, Nutrient Sensitive Waters (NSW), Water
Supply (WS), or Outstanding Resource Waters (ORW). The USGS quad map indicates that the
upper end of an intennittent unnamed blue line tributary to Clear Creek crosses the northwest comer
of the Study Area. Mecklenburg Polaris 3G GTS website indicates no streams on the parcel. National
Wetland Inventory maps indicate that this site has no areas mapped as wetland.
Mr. David Shaeffer of the USACE Wilmington District has conducted a site visit on October 20,
2016 to concur with the jurisdictional detenumation (SAW -2016-02014). All streams and wetland
boundaries on the site have been surveyed.
133d. Explain the purpose of the project:
The purpose of this project is to provide three new athletic fields, one baseball field, one future multi-
purpose field, 285 parking spaces, seating, and public rest rooms to satisfy the demand for these facill-
ties in the rapidly growing vicinity of the Town of Mint Hill. Additionally, a stormwater management
plan will capture storinwater runoff generated by any impervious areas of the site so that it can be
released slowly back into undisturbed wetland areas. A variety of public meetings, analysis of existing
facilities, a survey of anticipated needs, and staff input have determined the program for the site. This
site is located adjacent to an existing recreation facility. This site was selected due to its availability
within the Town of Mint Hill, the size and shape of the parcel, its proximity to other existing recreation
facilities, availability of public utilities, and generally open nature due to prior clear cutting thereby
reducing the need to impact forested lands.The site has been determined to be more suitable for this use
than other sites because it little existing high quality habitat due to clear cutting, no known significicant
historical or cultural resources base on a database search and comment from the NC State Historic

Preservation Office, and no existing record of protected species based on a database research and
comment from NC Natural Heritage Program.
133e. Describe the overall project in detail, including equipment to be used.
The Mint Hill Athletic Park project will consist of the construction of three athletic fields, one baseball
diamond, one future multi-purpose field, seating, parking for 285 cars, public rest rooms, and appropri-
ate stormwater managment BMPs. The construction process will involve installation of sediment and
erosion control practices, clearing, grading, and facility construction. Retaining walls will be used
where possible in order to minimize grading, stream, and wetland impacts. All appropriate sediment
and erosion controls will be implemented,inspected and maintained throughout the construction pro-
cess to prevent impacts to downstream receiving waters. Equipment to be used will consist of typical
construction equipment such as trucks, trackhoes, graders, tractors, and various manual tools.
Impacts to the wetland (W- 1) in the northern part of the site will be the result of the placement of fill for
the parking area required for the athletic fields. The grading is necessary in order to bring the elevation
of the center of the site up to the grade of the surrounding land and access from the entrance road. A
nine foot high retaining wall will be built at the edge of the parking area in order to avoid and minimize
wetland impacts. Storruwater runoff from the parking area will be directed into a stormwater BMP
situated in upland before being slowly released back into the remaining undisturbed wetland area over
a 2-5 day period in order to maintain the hydrology of overland runoff flowing into the wetland without
overwhelming it with flow all at once. This will mimic the natural pre -development hydrology of the
area.
Grading of the site for the baseball field will result in stream impacts (S- I and S-2) and wetland im-
pacts (W2 and W-3) in the southern comer of the site. Design standards of the baseball field for regu-
lation league play necessitate that the baseball field be of certain specified dimensions and contours.
Grading is necessary to drain runoff away from a high point at the infield towards lower elevations at
the outside edge of baseball field. This grading will generate a large amount of sheet flow towards the
southern edge of the baseball field. The elevation of the existing Brief Road is higher than the proposed
baseball field elevation at its southern comer. An excess amount of storruwater runoff from Brief Road
and the surrounding higher land will flow onto the baseball field unless it is captured and diverted
away. When combined with the sheetflow coming from the lower elevations of the baseball field,
enough volume and velocity will be created from a large store event that it could flow onto adjacent
properties and have enough energy to cause erosion. Therefore, a grassed swale is proposed to intercept
the stormwater flow and carry it around the southern edge of the field and eventually to the stream at
the lower end. In order to construct the grassed swale to direct flow away from the field and towards the
stream, it will need to be constructed so that is at least two percent in grade along its length so that it
will properly drain, but not so steep that it will erode due to velocity begiming at the elevation at the
upstream end at Brief Road and working down to meet the elevation at the stream bed. Constructiong
the swale will directly impact a portion of the wetland at Impact W-2, it will also very likely result in an
indirect impact of diverting flow away from the wetland, thereby depriving it of some of the hydrology.
There is already an existing upland area between the wetland and the stream that provides a hydrologic
surface connection between them. This upland area will partially be replaced by the swale but the
direction of flow will not be altered.
Calculations are attached for the cross section Sizing requirements of the swale based on storruwater
flows from the baseball field, Brief Road, and surrounding land as well as for calculations along its
length from Brief Road to the stream.
Retaining walls are proposed around the edges of the baseball field so that grading can be minimized
and to reduce impacts to stream and wetland.
A bio-swale will be planted along the downstream end of the swale for 200 feet before the runoff flow
enters the stream. The bio-swale will slow peak flows to reduce the possibility of ersion or headcutting
and will filter suspended sediments or pollutants before they reach te undisturbed portions of the peren-

nial stream. The bio-swale will be planted with a shrub layer of native wetland shrub species and an
herbaceous layer of native wetland grass -like plants.

No.
B5b, If yes. explain in detail according to the "help file" instructions.
D. Impact Justification and Mitigation
Dla. Specifically describe measures taken to avoid or minimize the proposed impacts in de-
signing the project.
A number of alternative layouts of program elements were originally reviewed to determine one that
avoids or minimizes impacts to streams and wetlands. In all of the layouts, the recreation fields are
required to maintain an axis that is as near to north -south as possible due to design standards of
recreation fields as a result of sun angles. In the first plans proposed, all fields were full sized and the
stormwater was being directed to the lowest point on the site for stormwater management. In the
final alternative that was selected, all stormwater was moved to adjacent upland areas and the pro-
posed site gading adjusted in order to direct the flow to these areas thus minimizing the originally
proposed impacts. The selected alternative also reduces the size of one of the fields and rearranges
the others so that impacts to streams and wetlands could be avoided and minimized. Additionally,
retaining walls will be used to reduce the area of grading thus minimizing impacts to both streams

and wetlands. Plans will implement a minimum of a 100' vegetated buffer from other downstream
waters. The first 3 0' of the buffer will remain forested, the remaining width will be grasses. Every
effort will be made to implement, inspect, and maintain proper sedimentation and erosion control
measures throughout the construction process to protect downstream receiving waters. Throughout
the construction process, buffers will be maintained along streams and equipment will be kept out of
these areas. Live concrete will be prevented from coming into contact with surface waters.
Total project impacts will be kept to a total of 119 If of stream and.307 acre of wetlands including
both direct and indirect impacts.
Dlb. Specifically describe measures taken to avoid or minimize the proposed impacts through
construction techniques.
Every effort will be made to implement, inspect, and maintain proper sedimentation and erosion
control measures throughout the construction process to protect downstream receiving waters.
Throughout the construction process, buffers will be maintained along streams and equipment will
be kept out of these areas. Live concrete will be prevented from coming into contact with surface
waters. A minimum of 30 feet of forested buffer will be kept undisturbed along all streams not
included as a part of the impacts for this project. Retaining walls will be constructed where practi-
cable in order reduce the amount of grading necessary therby reducing impacts to streams and
wetlands. With the exception of the direct and indirect impacts described in this application, there
will be no other impacts to streams or wetlands. All construction activities including clearing, grad-
ing, sedimentation and erosion control, and temporary access will be kept out of all streams and
wetlands.

Dear Ms. Wyant:
Subject: Mint Hill Athletic Park Project; Mecklenburg County, North Carolina
Log No. 4-2-17-190
The U.S. Fish and Wildlife Service (Service) reviewed your correspondence dated January 20,
2017, for the project referenced above. The Service submits the following comments in
accordance with the provisions of the Fish and Wildlife Coordination Act, as amended (16
U.S.C. 661 667e); the National Environmental Policy Act (42 U.S.C. §4321 et seq.); and section
7 of the Endangered Species Act of 1973, as amended (16 U.S.C. 1531 1543) (Act).
Project Descriptio
According to the infort-nation provided, you are seeking a NWP on behalf of your client, to
construct an athletic park on 27.3 acres of land in Mint Hill, North Carolina. The proposed
project would entail the construction of four athletic fields, public restrooms, and parking for 285
cars. The development would result in permanent impacts to 119 linear feet of intermittent and
perennial tributaries to Clear Creek and also 0.248 acre of headwater wetland. The parcel
currently primarily consists of undeveloped open space and according to the information
provided, was clear-cut in 2010. The proposed project would be designed with a 30 -foot
forested riparian buffer along Jurisdictional streams.
Federally Listed Endangered and Threatened Species
According to Service records, suitable summer roosting habitat may be present in the project
area for the federally threatened northern long-eared bat. However, the final 4(d) rule (effective
as of February 16, 2016), exempts incidental take of northem long-eared bat associated with
activities that occur greater than 0.25 miles from a known hibernation site, and greater than 150
feet from a known, occupied maternity roost during the pup season (June I — July 3 1). Based on
the information provided, the project (which may require tree clearing) would occur at a location
where any incidental take that may result from associated activities is exempt under the 4(d) rule.
According to Service records, no other federally protected species occur within the proposed
project's impact area. Therefore, we consider the requirements under the Act to be complete and
require no further action at this time. Please be aware that obligations under section 7 of the Act
must be reconsidered if. (1) new information reveals impacts of this identified action that may

affect listed species or critical habitat in a manner not previously considered, (2) this action is
subsequently modified in a manner that was not considered in this review, or (3) a new species is
listed or critical habitat is deten-nined that may be affected by the identified action.
Please consider the following recommendations in the interest of protecting fish and wildlife
resources:
Erosion and Sediment Control
Construction activities near streams, rivers, and lakes have the potential to cause water pollution
and stream degradation if measures to control site runoff are not property installed and
maintained. In order to effectively reduce erosion and sedimentation impacts, Best Management
Practices specific to the extent and type of construction should be designed and installed during
land -disturbing activities and maintained until the project is complete and appropriate storm
water conveyances and vegetation are re-established on-site.
A complete design manual, which provides extensive details and procedures for developing
site-specific plans to control erosion and sediment and is consistent with the requirements of the
North Carolina Sedimentation and Pollution Control Act and Administrative Rules, is available
at: httpL//Tortat.ncdenr.orL,/w��eb/tr/ ublications.
.............. 2 -
For maximum benefits to water quality and bank stabilization, riparian areas should be forested
but if maintained in grass, should not be mowed. We recommend planting disturbed areas with
native riparian species.
Measures to control sediment and erosion should be installed before any ground -disturbing
activities occur. Grading and backfilling should be minimized, and existing native vegetation
should be retained (if possible) to maintain riparian cover for fish and wildlife. Disturbed areas
should be revegetated with native grass and tree species as soon as the Project is completed.
Low IMact Development
We recommend the use of low -impact -development techniques,' such as reduced road widths,
grassed swales in place of curb and gutter, rain gardens, and wetland retention areas, for
retaining and treating storm -water runoff rather than the more traditional measures, such as large
retention ponds, etc. These designs often cost less to install and significantly reduce
environmental impacts from residential development.
Where detention ponds arc used, storm-watcr outlets should drain through a vegetated area prior
to reaching any natural stream or wctland area. Detention structures should be designed to allow
for the slow discharge of storm water, attenuating the potential adverse effects of ston-n-water
surges; thermal spikes; and sediment, nutrient, and chemical discharges. Also, because the
purpose of storni-water-control measures is to protect streams and wetlands, no
storm -water -control measures or best management practices should be installed within any
stream (perennial or intermittent) or wetland.
'We recommend visiting the Environmental Protection Agency's Web site cLmRL)&-
nonp(wint Vource )(J11111ionlurban runo for additional information and fact sheets
L --------------- jj jow...
regarding the implementation of low -impact -development techniques.

We also recommend that consideration be given to the use of pervious materials (i.e., pervious
concrete, interlocking/open paving blocks, etc.) for the construction of roads, driveways,
sidewalks, etc. Pervious surfaces minimize changes to the hydrology of the watershed and can
be used to facilitate groundwater recharge. Pervious materials are also less likely to absorb and
store heat and allow the cooler soil below to cool the pavement. Additionally, pervious concrete
requires less maintenance and is less susceptible to freeze/thaw cracking due to large voids
within the concrete.
Pf)Ihnqtf)r-,
Pollinators such as most bees, some birds, bats, or other insects including moths and butterflies,
play a crucial role in flowering plant reproduction and in the production of most fruits and
vegetables. Over 75% of flowering plants and about 75% of crops are pollinated by these
pollinators. A recent study of the status of pollinators in North America by the National
Academy of Sciences found that populations of honey bees (which are not native to North
America) and many wild pollinators are declining. Declines in wild pollinators are a result of
loss, degradation, and fragmentation of habitat, and disease; while declines in honey bees have
also been linked to disease. To off -set the overall impacts of development and/or to increase the
habitat and species diversity within the project area, we recommend the following measures be
implemented into project design:
I Sow native seed mixes with plant species that are beneficial to pollinators throughout
the site. Taller growing pollinator plant species should be planted around the
periphery of the site and anywhere on the site where mowing can be restricted during
the summer months. Taller plants, left un -mowed during the summer, would provide
benefits to pollinators, habitat to ground nesting/feeding birds, and cover for small
mammals. Low growing/groundcover native species should be planted in areas that
need to be maintained. This would provide benefits to pollinators while also
minimizing the amount of maintenance such as mowing and herbicide treatment.
Using a seed mix that includes milk weed species (milk weed is an important host
plant for monarch butterflies) is especially beneficial. The following website provides
a comprehensive list of native plant species that benefit pollinators:

.... .... . .. ....... ... ... .. ..... .... ... .. ..... ........ .... ..... .... ..... .... .... ..... .... .... ... ..
Additional information regarding plant species, seed mixes, and pollinator habitat
requirements can be provided upon request.
2. Provide nesting sites for pollinator species. Different pollinators have different needs
for nesting sites. Therefore, we recommend designing the project to maintain a
diverse array of habitats to accommodate varied pollinators from hummingbirds to
butterflies to bees. Hummingbirds typically nest in trees or shrubs while many
butterflies lay eggs on specific host plants. Most bees nest in the ground and in wood
or dry plant stems. For additional information and actions that can be taken to benefit
pollinators please visit the following web -site:

The North Carolina Natural Heritage Program (NCNHP) appreciates the opportunity to provide information
about natural heritage resources for the project referenced above.
A query of the NCNHP database, based on the project area mapped with your request, indicates that there are
no records for rare species, important natural communities, natural areas, or conservation/managed areas
within the proposed project boundary. Please note that although there may be no documentation of natural
heritage elements within the project boundary, it does not imply or confirm their absence; the area may not have
been surveyed. The results of this query should not be substituted for field surveys where suitable habitat exists.
In the event that rare species are found within the project area, please contact the NCNHP so that we may
update our records.
The attached 'Potential Occurrences' table summarizes rare species and natural communities that have been
documented within a one -mile radius of the property boundary. The proximity of these records suggests that
these natural heritage elements may potentially be present in the project area if suitable habitat exists and is
included for reference. Tables of natural areas and conservation/managed area within a one -mile radius of the
project area, if any, are also included in this report.
Please note that natural heritage element data are maintained for the purposes of conservation planning, project
review, and scientific research, and are not intended for use as the primary criteria for regulatory decisions.
Information provided by the NCNHP database may not be published without prior written notification to the
NCNHP, and the NCNHP must be credited as an information source in these publications. Maps of NCNHP
data may not be redistributed without permission.
The NC Natural Heritage Program may follow this letter with additional correspondence if a Dedicated Nature
Preserve (DNP), Registered Heritage Area (RHA), Clean Water Management Trust Fund (CWMTF) easement,
or Federally -listed species are documented near the project area.
If you have questions regarding the information provided in this letter or need additional assistance, please
contact Suzanne Mason at suzan ne. mason ancdcr. go or 919.707.8637.

NC WAM FIELD ASSESSMENT RESULTS
Evidence of stressors affecting the assessment area (may not be within the assessment area)
Please circle and/or make note on the last page if evidence of stressors is apparent. Consider departure from reference, if appropriate, in
recent past (for instance, within 10 years). Noteworthy stressors include, but are not limited to the following.
Hydrological modifications (examples: ditches, dams, beaver dams, dikes, berms, ponds, etc.)
Surface and sub -surface discharges into the wetland (examples: discharges containing obvious pollutants, presence of nearby
septic tanks, underground storage tanks (USTs), hog lagoons, etc.)
Signs of vegetation stress (examples: vegetation mortality, insect damage, disease, storm damage, salt intrusion, etc.)
Habitat/plant community alteration (examples: mowing, clear -cutting, exotics, etc.)
Is the assessment area intensively managed? E] Yes E No
Regulatory Considerations - Were regulatory considerations evaluated? ZYes E]No If Yes, check all that apply to the assessment area.
