This letter is to document that we have examined the partially completed wet pond
Stormwater Control Measure located on the Tramway South Apartment site at Tramway
Marketplace. We believe that with some remedial work to the embankment, the outlet
structures and grading of the forebay and main body of the pond, the device can be
completed as currently proposed.
Additional geotechnical testing and observations of the partially completed SCM will
continue prior to the start of construction and throughout the construction process to
determine if additional remedial measures are warranted.

TRAMWAY SOUTH APARTMENTS
STORMWATER CONTROL MEASURE DESIGN CALCULATIONS
STORMWATER MANAGEMENT PLAN MODIFICATION
ABSTRACT
This analysis has been conducted in order to comply with the requirements of the North Carolina
Department of Environmental Quality for a Stormwater Control Measure to serve the Tramway
Marketplace development at the southeast quadrant of NC 78 (Tramway Road) and US 1 and 15-501 in
Sanford, NC.
Tramway Marketplace was initially approved in 2012 as a 39.3 acre commercial development.
As part of the original wetlands permitting for the development, NCDEQ required that a stormwater
control measure be constructed that would treat the first one inch of runoff from the entire Tramway
Marketplace development and limitthe post construction runoff from the proposed developmentto less
that the predevelopment rates in the one year storm event.
The entire site was graded and streets were installed to produce a series of commercial lots fronting on
NC 78 and US 1 and backing up to Marketplace Drive. A CVS Drugstore was constructed on one parcel
and a Bojangles restaurant was constructed on another parcel. The larger tract south of Marketplace
Drive was never stabilized, and a temporary erosion control measure and unfinished StormwaterControl
Measure currently remain.
A 401 Water Quality Certification was issued on October 4, 2012 for the Marketplace at Tramway, DWR
Project # 12-0280v3. In order to meet condition 10 of that 401 Certification, a revised stormwater
management plan was submitted to the state and approved on July 8, 2013. A copy is attached for
reference.
Tramway South Apartments is a proposed 300 unit apartment community to be constructed upon
approximately 24 acres of the land located south of Marketplace Drive.
This analysis is to update the design of the required SCM based on current state standards and the
currently expected development of the entire site.
Offsite impervious areas will continue to drain to the SCM which will have sufficient hydraulic capacityto
safely convey that runoff through the SCM. However, the water qualityvolume will be based only on the
runoff from the onsite impervious areas within Tramway Marketplace..
The partially completed wet pond SCM includes an 11 foot high dam, 5.5' by 5.5' precast box riser and a
48" outlet pipe. We expect to use this riser, barrel and dam subject to inspection, repair and modification.
Awater quality orifice will be installed in the existing riser. The existing vegetation will be removed from
both the upstream and downstream faces of the existing dam and the surface of the dam recompacted.
The storage area behind the dam will be regraded and a forebay constructed.

Soil and Environmental Consultants, PA prepared a preliminarywetlands delineation of the site. Priest,
Craven & Associates, Inc. then surveyed in the flagged wetland locations. Copies of both are enclosed.
Based on the original approved stormwater management plan, the approved 401 permit and the approved
404 permit, we believe that Pond 2, Pond 3, W3 and the overland channel are all non -jurisdictional.
All construction will be within the prior permitted limits. All previously permitted wetland impacts were
completed in 2013 and 2014. All mitigation was also paid in 2013.
This analysis was prepared using the following available sources of information:
1. Boundary data from field survey by this office.
2. Lee County and City of Sanford GIS aerial topographic mapping
3. USDA, SCS, Soil Survey for Lee County, NC.
4. FEMA Flood Insurance Rate Map for Lee County, NC.
5. Preliminary development plans prepared by this office.
This analysis is based on the hydrologic and hydraulic principles and methodologies documented in the
following publications:
1. USDA, SCS, National Engineering Handbook, Section 4, Hydrology
2. SCS Technical Release 55
3. SCS Technical Release 20
4. Elements of Urban Stormwater Design by H. Rooney Malcom, P.E.
5. NRCS WinTR-55 Small Watershed Hydrologic Model.
6. Hydrology Studio 2022 v 3.0.0.26 Hydrographs Program
Cumulative curve numbers, time of concentration, runoff volumes and discharges for all Drainage Points
were calculated using SCS methodology contained within the WinTR-55 and Hydrology Studio
Hydrographs computer models.
Design calculations are included for the proposed stormwater management device within the project.
These calculations illustrate thatthe final design of the device will be in compliancewith State standards.

COMMENTARY AND OBSERVATION
DRAINAGE POINT 1
This Drainage Point is located at the existing dam of the wet pond SCM that was constructed to serve
the site. The post development drainage area at this location is the same as the predevelopment drainage
area.
The post development runoff rate at Drainage Point 1 is less than the predevelopment runoff rate in
the 1 year storm.
The results of the Hydrology Studio analysis of Drainage Point 1 in the 1, 2, 10 and 100 year storms are
contained in the Executive Summary of Results thatfollows this commentary. The detailed printout of the
analysis is also enclosed within this report.

In accordance with your written request of March 14, 2012, and the ensuing
administrative record, enclosed is a copy of a Department of the Army (DA) Permit authorizing
the permanent placement of fill material into 2.17 acres of jurisdictional wetland that drains into
an unnamed tributary of the Upper Little River in the Cape Fear River basin. These impacts are
associated with the project identified as the Marketplace at Tramway. The project consists of
nine out -parcels that front either Jefferson Davis Highway or Tramway Road, an anchor store,
other retail facilities, access roads, storm water management infrastructures, a sanitary sewer lift
station, and sufficient parking to support the commercial space proposed. The project site is
located on a 45 acre tract located in the southeast quadrant of the intersection of Jefferson Davis
Highway (US 1-15-501) and Tramway Road (NC Highway 78) in Tramway, southwest of
Sanford, Lee County, North Carolina.
Any deviation in the authorized work will likely require modification of this permit. If a
change in the authorized work is necessary, you should promptly submit revised plans to the
Corps showing the proposed changes. You may not undertake the proposed changes until the
Corps notifies you that your permit has been modified.
Carefully read your permit. The general and special conditions are important. Your
failure to comply with these conditions could result in a violation of Federal law. Certain
significant general conditions require that:
a. You must complete construction before December 31, 2022.
b. You must notify this office in advance as to when you intend to commence and
complete work.
c. You must allow representatives from this office to make periodic visits to your

You are authorized to perform work in the accordance with the terms and conditions specified below.
Project Description: This project, identified as the Marketplace at Tramway, is located on a 45-acre
tract in Tramway, Lee County, North Carolina. The project consists of nine out -parcels that front either
Jefferson Davis Highway (US 1-151501) or Tramway Road (NC Highway 78), an anchor store, other retail
facilities, access roads, storm water management infrastructures, a sanitary sewer lift station, and
sufficient parking to support the commercial space proposed. The project will permanently impact 2.17
acres of jurisdictional wetlands that drains into an unnamed tributary of the Upper Little River in the Cape
Fear River Basin.
To mitigate for wetland impacts, the permittee will make payment into the Barra Farms Phase II
Mitigation Bank for 4.34 acres of non -riparian wetlands within the Cape Fear River Basin (03030005),
which reflects a mitigation ratio of 2:1.
Project Location: The project site is located on a 45-acre tract located in the southeast quadrant of the
intersection of Jefferson Davis Highway (US 1-151501) and Tramway Road (NC Highway 78) in
Tramway, southwest of Sanford, Lee County, North Carolina. The geographic coordinates (in decimal
degrees) for the site are 35.4368 N. and-79.2158 W (NAD83/WGS84). The project impacts a wetland
that drains into an unnamed tributary of the Upper Little River in the Cape Fear River (HUC 03030004).
The Cape Fear River is currently, and historically has been, a navigable water of the United States.

APPROVAL OF MODIFIED STORMWATER PLAN
Dear Mr. Branch:
On October 4, 2012, the Division of Water Quality (the Division) issued a revised 401 Water Quality
Certification to impact 2.17 acres of 404 wetlands in order to construct the Marketplace at Tramway
Project in Lee County.
In order to meet Condition 10 of the 401 Certification for this project, a revised stormwater
management plan (SMP) for the Marketplace at Tramway, dated May 31, 2013, was received on June 6,
2013.
This approval is for the purpose and design that you described in your application. If you change your
project, you must notify us and you may be required to send us a new SMP. This approval requires to
you follow the conditions listed in the General Water Quality Certification for the project and the
following additional conditions listed below:
1. The SMP approved by the Division consists of one (1) wet detention pond and all associated
stormwater conveyances, inlet and outlet structures, and the grading and drainage patterns
depicted on plan sheets dated May 30, 2013. The plans and specifications for the wet detention
ponds approved by the Division are incorporated by reference into this approval and are
enforceable by the Division provided however that any modification of the design for the
stormwater management system that is accepted by the Division shall take precedence over the
original plans and specifications.
2. The maximum allowable drainage area for the approved wet detention pond shall be 2,001,750
square feet and the maximum allowable built -upon area shall be 1,320,000 square feet. Any
changes to these maximum areas shall require the applicant to submit and receive approval for
a revised stormwater management plan by the Division.

Reference: Marketplace at Tramway — Revisions to Approved SWM Plan (12-0280)
Lee County, North Carolina
Dear Annette:
Please find enclosed for your review one (1) copy of the revised Stormwater Management
(SWM) Plans and Computations for the Marketplace at Tramway (12-0280). The SWM plans
have been revised because the Owner recently purchased additional property (approximately
six (6) acres) adjacent to the project site that is better suited for the BMP wet detention pond
location. The revised plans show the BMP wet detention pond in this new location. Also, the
total impervious area shown on the SWM plan increased slightly due to some additional parking
added where the BMP wet detention pond was originally sited (however the % impervious has
decreased from the original plan due to the increased site area). The revised Impervious Area
Summary is also enclosed.
If you require any additional information, please contact me at your convenience. Thank you
for your assistance on this project.
Sincerely,

Detailed Delineation of Waters of the US
Suitable for Preliminary Planning Only
S&EC reserves the right to modify this map based on more fieldwork,
and any other additional information. Approximations were mapped using
topographic maps, air photos and ground truthing. If the site is going
to be disturbed, S&EC's detailed delineation should be approved and
permitted by the U.S. Army Corps of Engineers as required. If the user of
this work desires an accurate map of the regulated features flagged by
S&EC, they should retain a NC Registered Professional Land Surveyor to
locate S&EC's flagging.

NOTES TO USERS
NOTES TO USERS
Base map information and geospatial data used to develop this FIRMette were obtained from
various organizations, including the participating local community(ies), state and federal
agencies, and/or other sources. The primary base for this FIRM is aerial imagery acquired by
the State in 2010. Information and geospatial data supplied by the local community(ies) that
met FEMA base map specifications were considered the preferred source for development of
the base map.
See geospatial metadata for the associated digital FIRMette for additional information about
EFFECTIVE DATE base map preparation. Base map features shown on this FIRMette, such as corporate limits,
9/6/2006 are based on the most up-to-date data available at the time of publication. Changes in the
This is an official FIRMette of a portion of the effective panels listed in the Title Block shown
on Page 1. The information represented on this FIRMette was extracted from the effective
digital flood hazard data available at http://fris.nc.gov/fris.
Base flood elevation data, floodway, nonencroachment widths, information on certain areas
no in the Special Flood Hazard Areas protected by flood control structures, and other
pertinent data are available in the Flood Insurance Study (FIS) available at
http://fris.nc.gov/fris. Users should be aware that flood elevations shown on this FIRMette
represent elevations rounded to one tenth of a foot (0.1') and should be utilized in
conjunction with data available in the FIS.
corporate limits may have occurred since this map was published. Map users should consult
the appropriate community official or website to verify current conditions of jurisdictional
boundaries and base map features. This map may contain roads that were not considered in
the hydraulic analysis of streams where no new hydraulic model was created during the
production of this statewide format FIRM.
Flood elevations on this map are referenced to either or both the North American Vertical
Datum of 1988 (NAVD 88) or National Geodetic Datum of 1929 (NGVD 29), and are labeled
accordingly. These flood elevations must be compared to structure and ground elevations
referenced to the same vertical datum. To obtain current elevation, description, and/or location
information for bench marks shown on this map, or for information regarding conversion
between NGVD 29 and NAVD 88, please contact the Information Services Branch of the
National Geodetic Survey at [phone], or visit its website at https://www.ngs.noaa.gov.

'IMPERMEABLE SOIL/(I OEOMEMBRANE LINER
THE GTORMWATER CONTROL MEASURE 15 INTENDED TO MAINTAIN THE WATER ELEVATION AT THE NORMAL POOL ELEVATION INDEFINITELY ASSUMING NO EVAPORATION. BASED ON THE EESTNG SOILS, AND
THE LEVEL OF THE SEASONALLY HIGH WATER TABLE, A LINER MAY BE REQUIRED TO ENSURE THE ACTUAL RATE OF DROP OF THE WATER SURFACE IS LESS THAN 0.24 INCHES PER DAY, NOT INCLUDING
EVAPOTRANSPIRATION.
IT IS THE CONTRACTOR'S RESPONSIBILItt, IN CONSULTATION WITH THE PROJECT GEOTECHNICAL ENGINEER OR THE CONTRACTOR'S GEOTECHNICAL ENGINEER, TO DETERMINE IF A LINER IS NEEDED PRIOR TO
CONVERTING THE STORMWATER CONTROL MEASURE FROM A TEMPORARY EROSION CONTROL MEASURE TO A PERMANENT STORMWATER CONTROL MEASURE.
IF A CLAY LINER IS USED, PRIOR TO PLACEMENT, THE CONTRACTOR IS RESPONSIBLE FOR +WNG THE PROJECT GEOTEGHNICAL ENGINEER TEST THE UNER MATERIAL PERMEABILITY, DEVELOP ANY SPECIAL
CONDITIONS OF THE INSTALLATION SUCH AS PLACING THE LINER MATERAL ON THE WET SIDE OF OPTIMUM MOISTURE CONTENT, AND CONFIRMING THAT THE EXPECTED POND INFILTRATON RATE WITH THE
PROPOSED CLAY LINER WILL REDUCE SEEPAGE LOSS RATES TO THE PROJECT REQUIREMENTS. FOLLOWING INSTALLATION THE CLAY LINER THICKNESS IS TO BE CHECKED AT RANDOM LOCATION BY THE PROJECT
GEOTECHNIGAL ENGINEER TO VERIFY COMPLIANCE. IF A SYNTHETIC LINER IS USED, A QUALIFIED UNER DESIGNER SHALL BE CONSULTED. THE MANUFACTURERS INSTALLATON INSTRUCTIONS SHALL BE REVIEWED
BY TIE CONTRACTOR THE LINER DESIGNER, AND THE PROJECT GEOTECHNICA_ ENGINEER PRIOR TO INSTALLATION TO DETERMINE IF ADDITIONAL MEASURES ARE NECESSARY BASED ON LOCAL SITE CONDITIONS.
IN NO CASE SHALL THE DEPTH OF SOIL OVER THE LINER BE LESS THAN 12 INCHES IN ORDER TO PROTECT THE LINER FROM DAMAGE. THE DEPTH OF SOIL COVER OVER THE LINER SHALL BE CHECKED AT RANDOM
LOCATION5 BY THE PROJECT GEOTECHNICAL ENGINEER TO VERIFY COMPLLANCE. THE CONTRACTOR 5HALL WARN THE LANDSCAPING SUBCONTRACTOR ABOUT THE PRESENCE OF THE LINER. THE LANDSCAPING
SUBCONTRACTOR SHALL TAKE CARE IN THE INSTALLATION OF THE PLANTING NOT TO DAMAGE THE LINER. PRIOR TO INSTALLATION OF THE REQUIRED PLANT MATERAL, THE VALVE FROM THE WETLAND BASIN
SHALL BE CLOSED, THE POND FILLED, AND THE ABILITY TO HOLD WATER PER THE PROJECT REQUIREMENTS CONFIRMED. THIS TEST SHALL BE REPEATED AFTER THE INSTALLATION OF THE PLANT IIATERAL.
REGARDLESS OF THE CARE TAKEN DURING INSTALLATION AND THE TESTING AND SUPPORTING DOCUMENTATON OF THE PROJECT GEOTECHNICAL ENGINEER, IF THE LOSS RATE FROM THE POND EXCEEDS THE
PROJECT REQUIREMENTS, THE CONTRACTOR IS RESPONSIBLE FOR REDUCING THAT RATE TO THE PROJECT REQUIREMENTS BY MEANS THAT STILL PROVIDE ACCEPTABLE WATER QUALTY AND CONDITIONS
APPROPRATE FOR PLANT GROWTH, AT HIS COST. THE CONTRACTOR IS RESPONSIBLE FOR QUALITY CONTROL TESTING DURING CONSTRUCTION TO VERIFY THE LINER, CLAY OR SYNTHETIC, 15 INSTALLED IN
ACCORDANCE WITH THE PLANS, RECOMMENDATONS OF THE GECTECHNIGAL ENGINEER, AND MANUFACTURER'S INSTRUCTIONS, A REPORT OF THE INSTALLATION AND AS BUILT CONDITIONS SHALL BE PROVIDED
TO THE OWNER SY THE CONTRACTOR'S PROJECT GEOTECHNICAL ENGINEER AFTER CONSTRUCTION. IF FOR ANY REASON THE LOSS RATE EXCEEDS THE PROJECT STANDARD, THE CONTRACTOR SHALL BE
RESPONSIBLE FOR PROVIDING REMEDAL MEASURES, UNDER THE SUPERVISION OF A QUALIFIED GEOTECHNICAL ENGINEER, TO BONG THE LOSS ROTE INTO COMPLANCE WITH THE ABOVE STANDARD.

2. TOPSOIL SHOULD BE SPREAD TO A MINIMUM DEPTH OF 4" THROUGHOUT THE VEGETATED SHELF, INCLUDING THE DAM PRIOR TO
SEEDING/PLANTING VEGETATION. TOPSOIL SHOULD BE HAND -TAMPED AND LIGHTLY COMPACTED WHILE MAINTAINING THE
MINIMUM 4" OF TOPSOIL DEPTH FOR PLANT GROWTH. CONTRACTOR TO ACCOUNT FOR SETTLING OF LOOSELY COMPACTED
SOILS FOR THE WETLAND PLANTING SUCH THAT ONCE SETTLING OCCURS THE FINAL GRADES AS SHOWN ON THESE PLANS
ARE MAINTAINED.
3. SEE NOTES RELATED TO VEGETATED SHELF SOIL ANALYSIS AND TREATMENT ON THIS PAGE.
4. ACCEPTABLE FERTILIZERS CAN BE: MINERAL, ORGANIC (MANURE), COMPOST OR GREEN CROPS.
5. CONTRACTOR TO WORK WITH SOIL SCIENTIST TO ENSURE SOILS ARE ADEQUATE TO SUPPORT ESTABLISHMENT AND GROWTH
OF THE PLANTINGS. CONTRACTOR TO AMEND SOILS AND INSTALL SOILS IN PLANT AREAS PER DETAILS, SOIL SPECIFICATIONS,
NGDENR SPECIFICATION, AND SOIL SCIENTIST RECOMMENDATIONS.
6. THE OPTIMAL PERIOD FOR PLANTING HERBACEOUS VEGETATION EXTENDS FROM LATE MARCH TO EARLY JUNE. THE BEST TIME
TO PLANT SHRUBS IN A WET POND IS FROM NOVEMBER TO MID MARCH. CONTRACTOR SHOULD SCHEDULE PLANT
INSTALLATION ACCORDINGLY.
'I. ONCE THE PLANTINGS HAVE BEEN DELIVERED TO THE SITE FROM THE NURSERY THEY SHOULD BE FREQUENTLY WATERED,
FERTILIZED AND SHADED UNTIL THEY ARE INSTALLED.
5. ALL DISTURBED AREAS AROUND THE OUTSIDE OF THE WET POND SHALL BE SEEDED WITH A LAWN AREA SEED MIX (PER
SEEDING SPECIFICATIONS) NATIVE GRASSES, LEGUMES, CLOVERS AND WILDFLOWERS.
9. PLANTING AREAS SHOWN IN THE VEGETATED SHELF SHALL BE PLANTED IN A "NATURALIZED" MANNER WITH PLANTS GROUPED
WITHIN THE VEGETATED SHELF AND SPACED ON -CENTER AS OUTLINED IN THE CHART.
10. IF THE WET POND WAS USED DURING CONSTRUCTION AS FOR EROSION CONTROL, THE BASIN MUST BE CLEANED OUT,
GRADED, APPROPRIATE AREAS COVERED WITH 4: OF TOPSOIL AS SPECIFIED IN NOTE #2 ABOVE, AND VEGETATED WITHIN 14
DAYS OF CONSTRUCTION COMPLETION. THE CONVERSION OF THE DEVICE TO A PERMANENT DEVICE SHOULD NOT OCCUR
UNTIL ALL CONSTRUCTION IS COMPLETE AND THE DRAINAGE AREA TO THE SCM IS COMPLETELY STABILIZED WITH PAVEMENT,
STRUCTURES, AND VEGETATION OR BASED ON ALTERNATIVE DIRECTION BY THE REVIEWING AGENCY. PLANTINGS ON THE
VEGETATED SHELF SHOULD BE INSTALLED PER NOTES ABOVE.
11. THE SCM DRAIN SHOULD BE FULLY OPENED FOR NO MORE THAN 3 DAYS PRIOR TO THE PLANTING DATE TO PRESERVE SOIL
MOISTURE AND WORKABILITY.
12. ALL NEW PLANTINGS ON THE VEGETATED SHELF ARE TO BE WATERED AS REQUIRED DURING INITIAL GROWING SEASON TO
KEEP PLANTS HEALTHY AND PROMOTE GROWTH.
13. A MINIMUM TWO-YEAR WARRANTY PERIOD SHALL BE PROVIDED BY THE CONTRACTOR FOR PLANT SURVIVAL/REPLACEMENT.
14. AT THE END OF THE FIRST YEAR AND AGAIN AT THE END OF THE TWO-YEAR WARRANTY PERIOD, ALL PLANTS THAT DO NOT
SURVIVE MUST BE REPLACED. ESTABLISHMENT PROCEDURES, SUCH AS CONTROL OF INVASIVE WEEDS, ANIMAL. AND VANDAL
DAMAGE, MULCHING, RE -STAKING, WATERING, AND MESH OR TUBE PROTECTION REPLACEMENT, SHALL BE IMPLEMENTED TO
THE EXTENT NEEDED TO ENSURE PLANT SURVIVAL. STAKING MUST BE REMOVED AFTER ESTABLISHMENT (APPROXIMATELY 12
MONTHS), TO PREVENT GIRDLING (STRANGLING) OF ALL WOODY PLANTS.
