SUBSURFACE EXPLORATION AND ENGINEERING EVALUATION
PROPOSED WAXHAW DEVELOPMENT
HISTORIC VENTURES, LLC
WAXHAW, NORTH CAROLINA
EEI PROJECT NUMBER 4429-G-NC
Dear Mr. Patch,
Eagle Engineering Inc. completed a Preliminary Geotechnical Subsurface Exploration dated June
23, 2010 for the above referenced project. Our drilling program included 15 soil test borings
drilled to depths of 20 to 50 feet below the ground surface. It is our understanding that a request
has been made as to the expected Seasonal High Groundwater Table within the proposed BMP
for the site.
The test borings B-14 and B-15 were advanced within the proposed water quality/detention pond
indicated groundwater at elevations ranging from 7.5 to 14.5 feet bgs. Based upon the grades
indicated upon the supplied site plan, the existing ground surface difference between the two
borings is approximately 5 feet with a corresponding water surface elevation ranging from
approximately 610 to 612 MSL. Seasonal high water may be estimated to be 3 feet higher than
the indicated current levels or at an elevation of 608 MSL.
As you review the applications/maps and have any questions please do not hesitate to contact our
Office.
Sincere]•

Environmental Impact Statement for Waxhaw Mixed Use Development
Historic Venture, LLC proposes to develop Waxhaw Mixed Use Development on
approximately 14.9 Acres, in Waxhaw, Union County, North Carolina. It lies just west of
NC Hwy 16, just north of Price Street and just cast of Broad Street. Based on request
lion the Town of Waxhaw, and an Environmental Impact Statement in accordance with
16.2.2.3 D - Additional inf m-nation, is being; provided.
1) Description of Proposed Project
• Site area: 14.9 acres
• Existing; zoning; is primarily CU-CPUD (allows commercial, industrial, and
residential), R-3 (residential- only a small portion of the site is R-3), and C-2
(commercial- only a small portion orthe site)
• Proposed zoning; is CD C-4, proposed uses arc Mixed use including commercial,
civic, and office (201,600 sl'total)
• Site is located within a 5 minute walk from the "heart oi'downtown" (intersection
of 16 and 75) and is defined as within the downtown historical district on the 2030
comprehensive plan
• The project proposes approx. 18% pubic open space including; a 0.75 ac public
green/square
• Project includes multimodal streets (4' bike lanes and sidewalks on both sides of
the street).
2) Purpose and Need of Project
The proposed Waxhaw Mixed Use Development is intended to provide retail, commercial
and civic land uses in the Town of Waxhaw. The project has been planned to he blend in
with the existing; character of' downtown Waxhaw, including tree line streets, and
comfortable and safe pedestrian areas. The proposed plan meets the following objectives;
2

• The 2030 Comprehensive Plan for the Town envisions the expansion of the
Waxhaw's Central Business District from its current location and encourages the
presmation of -the existing character ofdowniown Waxhaw.
• The UDO states that purpose of the C-4, Central Business District is to encourage
land uses which are characteristic of main streets and pedestrian districts. The
district allows for it mixture of complementary land use types, which includes
retail, offices, commercial services and civic uses. Development should be
Compatible With the fabric of the surrounding Uses and pic-existing development to
promote an active live, work, play setting.
+ The site meets the 2030 comprehensive plan in the tbilowing ways:
- Provides a compact urban fbrn-. flan is mixLd use, increase densities in
downtown, protect rural character of -area by redevelopment
- Increase transit options including bikes, sidewalks, etc
- Private investment in public infrastructure and parks
+ The toilowing statement was presented by the Town Planning and Zoning
Administrator to the Board on 3-9-10: "Small Town Main Street --Preliminary
results from a niarkct study that is to be released in April indicate that the
downtown area could support an additional 200,000 square feet of retail space."
• According to rezoning sheet CD-2 (parking calculations) the project proposes
approx. 40,000- 50,000 sfof retail development (not including the rec. center)
The project proposes a 60 room hotel, an aquatic fitness/recreation center, and a
proposed Civic building, currently submitted to the Town for a Iulure Town hall
through a public RF P process.
3 Pro'ects proposed b , Public Entities — Not Applicable
4) Environment Affected by the Project
a) General Site Location and Site Information
The Waxhaw Mixed Use Development is located in the town of' Waxhaw in Union
County, North Carolina. The site is approximately 14.9 Acres in sire and is located on the
USGS Catawba NB, (NCSC) 7.5 minute Quadrangle (34.9275°N, 80.7462°W (NAD27)).
It lies just west of NC Hwy 16. just north of Prig Street and just cast of Broad Street.
Soils include Gcorgcville silty clay loam, Tarrus gravelly silty clay loam, and Tarrus-Urban
land camplcx. The tollography consists of upland flats grading into gentle to moderate
slopes, with the elevation ranging from 620 to 670 t1.
3

h) Existing Site Conditions
']'his site is currently in a suburban setting. There are existing homes and residential lands
that are under active management, as well as remnants of old homes and outbuildings, and
a few commercial enterprises near NC 16. The site is composed of vegetation typical of a
suburban residential setting including typical non-native cultivated brasses, 1-orbs and
shrubs and exhibiting; segmentation of the landscape. There are some large trees (in the
site, including White Oak (Quercus rubra), Red Oak (Q. rubru), Sweetgum (Liquidambur-
stvraciJlua), Tulip Poplar (1_iriodendrorr rrrlipi/era} and Red Maple (Acer rubr•a) in the
vicinity of former residential properties. A large portion of the site; is maintained as an
open fescue (1=estuca sp.) field, and is actively maintained by mowing;. There is an old
pulley with moderate east and west facing slopes with Loblolly Pines (Prruus 1aefla),
Shorticaf Pine (1'inus echinala), and Swcctgum. There are hedgerows scattered on the
site composed of Privet (Lignstrum sinense), Japanese Holly (Ilev cronalu), Boxwood
(HtLvus senipery revs), blackberry (Rubes s/) ), and autuin olive (L"leugnur umbellate).
Vines Include Japanese honeysuckle, greenbrler, muscadine grape, and poison Ivy
(Too doJ lenelron radrearra).
The site drains to a tributary of Twelventile Creek in the Catawba River Basin. The small
agricultural pond that appears on the USGS Kip does not exist. Based on the former
pond's position in the landscape, it appears the pond may have been partially excavated
into the ridge. The remnant of a diversion ditch on the west side ofthe former pond bed
appears to have naturalized and is partially eroded by head cutting. The roadside edge, and
maintained field/woodland edges have no identifiable traditional natural community type.
c) .Jurisdictional Waters of the United States
Waters ofthe U.S., including wetlands are regulated by Section 404 and 401 ofthe Clean
Water Act (CWA) and these are administered and enforced by the U.S. Army Corps of
Engineers (USACE), and the North Carolina Department and Environment and Natural
Resources (NCDENR). The site was evaluated by biologists utilizing; the Routine On -Site
Determination Method according; the 1987 Corps of Engineers Wetland Delineation
Manual plus Appendices in August 2008 and re-evaluated in March 2010. In addition to
wetlands, the site was evaluated for the presence of surface waters in accordance with
NCDENR stream determination guidelines and for open waters such as impounded
streams. Permits are required from these agencies to impact these areas.
Based on the site evaluation and verification by the NCDENR (Alan Johnson),Naters of
ithe U.S, and the State of North Carolina were not identified within the project boundaries.
Based on coordination with the USACE (Stephen Chapin), they will accept the NCDENR
detennination.
Therefore based on a review of the current plan, a permit from the USACE and/or
NCDENR to impacts Waters of the U.S. will not be required.

d) Threatened and Endangered Species
Information gathering and surveys were conductcxi in August 2008 and March 2010 to
determine if terrestrial endangered species and/or their habitat are present on the site. The
North Carolina Natural Heritage Prograrn's online database was referenced to determine
the occurrence of'plant species of concern for the Waxhaw Quad.
• One plant species with the rank of Federally Endangered (E) is listed as Currently
occurring in the Waxhaw Quad: Schweinilz's Sunflower (Helial7l ws schimeinitzii).
Schwcinitz's Sunflower requires open habitat with little shade such as roadsides,
power -line riglits-ot=way (PLIZOW) and woodlands and field edges.
• One plant species with the rank of Federally Endangered (E) is listed as historically
occurring in the Waxhaw Quad: Michaux's Sumac (Rhue michaurii). Michaux's
Sumac requires habitat of sandy forests and woodland edges. The historic
designation for this species rneans that it is either extirpated from the county, or
there have not been any recent surveys to verify its continues] existence.
• One plant species with the rank of Candidate (C) is listed as currently occurring in
the Waxhaw Quad: Georgia Aster (S),nrplrvowichum georg a►7urn). Georgia Aster
requires open habitat with little shade, such as roadsides, power -line rights -of -way
(PLROW) and woodlands and field edges.
• One plant species with the rank of Federal Species of'Concern (FSC) is listed as
currently occurring; in the Waxhaw Quad: Carolina Bird -foot Trefoil (ALntispon
helleri). Georgia Aster requires open habitat with little shade, such as roadsides,
power -line rights -of -way (PLROW) and woodlands and field edges.
Conclusion and Recommendations ReLlarding Terrestrial Species:
This site has no suitable habitat for any of the terrestrial species of concern listed for the
Waxhaw Quad. Intensive management including cultivation of non native turf grasses
and shrubs, and active niowing throughout and along the roadsides have created a non -
natural environment on the site. I have no recommendations for the site pertaining to any
terrestrial species of-conccm.
The Carolina hcelsplitter (Lasin grona decorala), is a federally Endangered freshwater
mussel. It prefers shaded areas either in a pondel portion ol' a small stream or in runs
along; steep banks with moderate current. Primary habitat is waters less than three feet
deep with a sots mud, muddy sand; or shady gravelly substrate. It is normally restricted to
protected silted areas or under banks especially associated with obstructions such as
stumps or fallen trees. Currently the Carolina heelsplitter has a very fragmented, relict
distribution. It is known to be surviving in only six strearns in the Catawba River Basin.

Catawba River Basin:
I . Sixmile Creek - Lancaster County, SC
2. Waxhaw Creek -Union County, NC and Lancaster County, SC
3. Cane Creek -Lancaster County, SC
4. Gills Creek -Lancaster County, SC
5. South fork fishing Creek-Chestcr County, SC
6. Bull Run Creek/UT Bull Run Creek/Beaverdam Creek (Rocky Creek Subbasin)-
Chester County, SC
Conclusion and Reconiniendation
According to available information, the Carolina heelsplitter is not expected to occur in
Twelvetnile Creek downstream of this project. Based on a site evaluation and verification
by NCDENR there are no impacts to regulated stream, wetlands, or other surface waters
on the project site. Since there are no streams oil this project site, this species will not
occur on the site.
There are no impacts expected to protected species as a result of this project.
5) Short and Long-term Consequences of the Proiect on the
Environment Includinp, Anv Adverse Environmental Impacts Which
Cannot Be Avoided.
A) Resident species of immobile plant and animal species are likely to he impacted or
eliminated by construction. Large mammals such as deer and raccoon will seek refuge in
larger undisturbed areas while many mobile animals such as rabbit, squirrels, opossum, and
passerine birds such as sparrow, chickadee, cardinal, blue jay, mockingbird, mourning
dove, and killdeer adapt to urbanization.
B) A major pollutant of Twelvcmile Creek is the heavy amount of siltation from
development, as well as certain agricultural practices causing erosion such as over -grazing
and trampling stream banks by livestock. Without adequate protections, construction of
the project could create additional temporary and permanent sedimentation impacts
downstream of the project.
C) Without adequate protection, increased velocity and volume of runoff from
impervious surfaces and parking areas could contribute to increased flooding, and erosion
of' streams and stream banks. Runoff from impervious surfaces and parking lots can
introduce additional pollutants to what likely currently exists downstream of- the project
causing adverse impacts to water quality.
ro

6 List of Means That Could Be Enij2loved to Mitigate Any Negative
Effects on the Environment Caused By This Project
A) Landscaping
Based on a review of the proposed plans and discussions with the project developer and
planners, the dcvelopmcnl will include areas that will be pleasantly and aesthetically
landscaped with trees, sbrubs, groundcovers, and grass, including native plant materials.
Landscaping will be conducted in accordance with the development standards for Waxhaw
Mixed Use Development provided by the developer as described below.
I ) Buffers will confbrm to the standards specified in Section 9.8 of the UDO.
2) The developer shall install a landscaped area along the Broad Street frontage of the
Site. The landscape area shall contain a mixture of vegetation types (large
maturing trees, evergreen trees, understory trees, shrubs, ctc). The proposed
landscape area planting plan shall be approved by the Planning Department during
the construction document phase of the permitting process (per section 9.8.1-B-2
ofthe UDO).
3) Street tree locations depicted on the Conditional District Site Plan are preliminary
and may be altered or modified to accommodate changes to the plan.
4) In addition to internal landscaping; required by the UDO, the devclopilicIlt shall
provide internal landscaping; that achieves the fbllowing goals:
To support sate pedestrian circulation
ii. To promote the use ofdrought tolerant and low maintenance plants and
avoid invasive species.
iii. To visually emphasize pedestrian circulation, public open spaces, and focal
points.
iv. A detailed buffer plan shall be submitted for the area behind Building `G'
ti)r staff review and approval as part of the preliminary plan review. Also, all
associated landscaping for that area shall be installed prior to the issuance of a
Certificate of Occupancy for Building `G'.
%r. A detailed screening; plan shall be submitted ibr the area between Building;
`A' and Building; `B' for staffreview and approval as part ofthe preliminary plan
review.

B) Tree Preservation and Mitigation
1) Tree preservation and mitigation will be delineated through a collaborative process
between the Zoning Administrator; developer, and a North Carolina registered urban
lorester, registered landscape architect, or ISA certified arborist. Collaboratiort between
these parties will promote appropriate tree preservation measures for the Site and will
strike an appropriate balance of tree protection, preservation, and planting in an urban
environment while accomplishing the overall intent ofthe UDO.
2) Where new tree plantings are proposed within the Site the Petitioner shall utilize
sustainable planting practices (soil enhancements, structural soil, etc.) to ensure that newly
planted trees are provided on optimal growing environment. The Petitioner shall submit
the proposed planting plan and details to the Town of Waxhaw (or Town representative
such as the Union County Urban Forester) for review and approval.
3). Petitioner shall save existing mature trees within the setback along the Broad Street
and Price Street frontages to the maximum extent feasible.
C) Sedimentation and Erosion Control and Stormrvater Management
I ) To minimize temporary impacts and permanent impacts to downstream waters
from construction, an approved Sedimentation and Erosion Control Plan by the North
Carolina Department of I?.nvironment and Natural Resources — Division of Land Quality
must be obtained and implemental prior to grading the site.
2) Stormwater quantity control shall follow the requirements set forth in the Town of
Waxhaw Stormwater Design Manual. Storm water quality treatment shall be provided per
the North Carolina Division of Water -Quality Best Management Practices Manual, July
2007.
' 3) The location, sire, and type of 9torniwater management systems depicted on the
Conditional District Site Plan are subject to review and approval at the time of full plan
submittal. Adjustments may be necessary in order to accommodate stormwater treatment
requirements and natural site discharge points.
4) Discharges from stormwater tacilities shall be at non -erosive velocities in
accordance with Waxhaw and NCDENR requirements.
5) In order to achieve the maximum regulatory credits with respect to pollutant
removal per the North Carolina Division of Water Quality Best Management Practices
Manual, July 2007, a monitoring program shall be established, Atler tie water quality
pond is established, it shall be inspected on a regular basis. Records of' operation and
maintenance shall be kept in a known location and shall be available upon request by the
8

Town of Waxhaw. Any problems fr)und during inspection shall be repaired immediately.
Monitoring shall include an evaluation ol'the following elements:
a) Aquatic environment: water clarity and algal growth
b) Vegetation: The vegetated shelf shall be properly maintained it) order to achieve
additional pollutant removal and in order to prevent bank erosion. Bare spots, weeds, and
invasive species shall be noted and remedied as soon as possible to prevenr larger
problems. Grass shall be cut (where appropriate) and debris shall be removed in order to
ensure a functional and attractive BMP facility.
c) Sediment Build-up: Sediment accumulation shall be monitored through it visual
inspection of the basin bottom and the sediment accumulation depth marker. When the
specified depth of sediment has been reached in the forebay or main basin, the sediment
shall be removed and repaired as designed.
Therefore with the implementation of stormwater management protections, tree
Preservation, and landscaping as stated above, it appears that the potential negative eflects
on the environment will be mitigated.
Conclusion
On the basis of environmental studies and the proposed mitigation measures, it is not
anticipated that this project will have significant adverse of iecls on the quality of the
human and natural environment.
Please contact me ifyou have any questions or require additional explanation. Thank you
for your consideration.

Hy,
Per our policies, I can grant up to a 30 day extension. If you need beyond that, I'll have to return it as incomplete. Then
it would need to be resubmitted as a new application with all required items, including the application fee. Let me know
how you want to proceed.
Thanks.

Thank you for the reminder. The project is on hold for now. We are trying to sort out a few site design elements with
Town; therefore, we wanted to wait a little longer to see if it would affect the BMP design before proceeding with the
revisions.
On that note, please consider this email as our `request for an extension'. Could we have a target date on re -submittal
beyond the 3120? If so, that would be ideal.
Let me know if there is anything else I need to do for the extension request.
Thanks again.

WAXHAW MIXED USE DEVELOPMENT
STORMWATER MANAGEMENT SYSTEMS
NARRATIVE
DPR Project No, 10006
December 21, 2012
The project site, Waxhaw Mixed Use, is located at the Broome Street/Highway 16 and Church Street
intersection, Town of Waxhaw, NC. The total site area is +/- 14.9 ac. The approximate Drainage Area
(1A) to the Stormwater BMP facilities is +/- 11.4 ac. The existing condition consists of woods, grass
lands, and streets, buildings with parking. The site will be developed/re-developed with road
improvements, mixed use buildings, and associated features.
A Stormwater BMP Wet Detention Pond was proposed and designed per latest NCDENR-DWQ
Stormwater BMP manual and Town of Waxhaw Ordinance. 90% TSS removal design criteria was used
as no 'vegetated filter' is provided at the BMP pond outlet. Topographic maps and field observations
were used to delineate the watershed basins and hydraulic path feeding into the study conveyance
system. With this information, hydraulic length, time of concentration (TOC), and basin slope were
determined for the pre -developed condition. TOC of 5 min. was used for all post -developed condition.
The composite curve number (CN) was calculated based on the hydrologic soil types and groups from the
U.S. Department of Agriculture soil survey for the pre -developed and post -developed conditions. The
total impervious of the development was calculated.
Per Phase 2 NPDES, development within 'Catawba' watershed is required to provide water quality control
and treatment (WQv) for the First Inch of rainfall. The WQv was quantified using the Schueler simple
method.
Furthermore, Hydraflow Hydrograph models were developed using SCS Unit Hydrograph to determine
the peak flows and peak times for the 1-year, 2-year, 10-year, 25-year, 50-year, and 100-year storms with
24-hour storm distribution. Union County rainfall intensity in inches per hour was used. Town of Waxhaw
jurisdiction requires volume control (detention) up to 10-yr storm. The proposed BMP facility provides
detention up to 25-yr storm. 100-yr storm stays inside the pond with provided 1.0' freeboard.
A Bypass Drainage Area (2D) is approximately 3.5 ac, in which the existing build upon area (BUA) was
approximate 2.5 ac. This area is `re -developed' with approximate 3.05 ac of BUA; in which, BUA of 2.5
ac. will be credited and bypassed. The difference of 0.55 ac. BUA is counted in the BMP Pond design
above.
The enclosed calculation package is to show the results of the proposed stormwater BMP for the
proposed development. Detailed maps, calculations, results, and details are included. Also refer the
Grading Plan, BMP Plans and details for complete information.
