SECTION I - EROSION AND SEDIMENT CONTROL
1.1 PROJECT DESCRIPTION
This document addresses expected erosion and sediment control and storm water
management from the proposed redevelopment of McDonald's restaurant in Wilmington,
North Carolina. The property is located at 4301 Market Street. There is an existing
McDonald's restaurant that occupies this current location. The proposed construction will
consist of total demolition of the existing restaurant and parking and construct a single-story
6,358 square foot building with curb islands, associated parking, a storm water
detention/water quality facility.
In section II of this document we will discuss storm water detention/water quality for this
site. The runoff from this site will either be collected by a storm drainage system or will
sheet flow through the parking areas to where it will either discharge into the proposed
detention/water quality facility. See the appendices for supporting calculations.
Section III of this document addresses water quality. Per NCDENR, water quality must be
provided for the entire site. Refer to section III and appendices for supporting information.
1.2 EXISTING SITE CONDITIONS
The existing site consists of a McDonald's building and associated parking. Access to the
proposed site will be granted from Market Street.
1.3 ADJACENT AREAS
The site fronts onto Market Street which bounds the site to the south. The adjacent lot to
the north is vacant. Travel Inn motel is located on the lot to the east and a Quick Lube
exists on the lot to the west.
1.4 CRITICAL EROSION AREAS
The most critical erosion area will be the surface of the working area during construction
operations. If grass is not established on dormant denuded areas then there is a significant
potential for the covered areas to be eroded and for sediment to be carried in the runoff. To
minimize the potential for erosion, covered areas that are temporarily inactive will be seeded
within 14 working days after placement of the soil cover.
1.5 EROSION AND SEDIMENT CONTROL MEASURES
All vegetative practices and erosion and sediment control features shall be designed,
constructed and maintained in accordance with the North Carolina Erosion and Sediment
SWM Report
McDonald's—Wilmington,NC / ;C•l''''6� '�"'".r
September 12,2007
y`

Control Planning and City of Wilmington Standards and Specifications. The features are
designed to control runoff resulting from the 10-year frequency storm. Supporting design
calculations are attached. Plan-view drawings with details are also provided.
1.5.1 Stabilized Construction Entrance/Exit (Reference NCESCPDM STD &SPEC 6.06)
Stabilized construction entrances should be used at all points where traffic will be leaving a
construction site and moving directly onto a public road. Wash down facilities may be
required as directed by your local approving agency. Construction entrances should be used
in conjunction with the stabilization of construction roads to reduce the amount of mud
picked up by vehicles.
1.5.2 Silt Fence (Reference NCESCPDM STD & SPEC 6.62)
Sediment fences will be provided down gradient of the proposed site grading at the locations
shown on the drawings. The sediment fences will direct flow to either a sediment deposition
area behind the fence or to a sediment trap. Silt fences are not to be used across channels or
in areas of concentrated flows.
1.5.3 Drainage Swale (Reference NCESCPDM STD & SPEC)
Diversion ditches will be utilized to direct overland flow to appropriate sediment and
erosion control devices.
1.6 VEGETATIVE STABILIZATION
Vegetative cover shall be re-established within 15 working days or 30 calendar days after
completion of the activity,whichever period is shorter.
1.7 TEMPORARY STABILIZATION
Disturbed areas will be vegetated in accordance with section 3.0 of the North Carolina Erosion
and Sedimentation Control Design Manual and the seeding specifications. Temporary control
features will remain in place and will be maintained until the up-gradient disturbed area has
been stabilized with vegetative cover.
1.8 MAINTENANCE
All erosion and sediment control measures will be checked for stability and operation
following every runoff-producing rainfall but in no case less than once every week. Any
needed repairs will be made immediately to maintain all measures as designed.
The sediment basin shall be inspected regularly during land disturbing activities and after
each runoff-producing rainfall. Sediment shall be removed and the basin restored to its
SWM Report

original dimensions when sediment has accumulated to one-half the design depth of each
basin. Portions of the basin's gravel facing that are contaminated by sediment shall be
replaced with fresh gravel during each sediment removal episode.
Sediment fences shall be inspected at least once a week and after each rainfall. Repairs shall
be made immediately. Sediment deposits shall be removed as needed to provide adequate
storage volume for the next rainfall event, and to reduce pressure on the fence. Fencing
materials and sediment deposits shall be removed, and the area brought to grade following
stabilization of up gradient disturbed areas.
1.9 CONSTRUCTION SEQUENCE
1. Construct entrance pad.
2. Install gravel construction pad, temporary diversions, silt fence, sediment
traps or other measures as shown on the approved plan.
3. Install storm drainage.
4. Place stone on entrance drive and parking areas.
5. Install inlet protection on storm inlets.
6. Excavate and promptly seed/mulch perimeter areas of site.
7. Grade and excavate for building pad and foundation area.
8. Construct building.
9. Fine grade around building, spread topsoil, seed or sod as applicable.
10. Fine grade parking areas, add stone where necessary, and construct
structures.
11. Fine grade and seed or sod disturbed areas.
12. Remove all erosion control structures.
13. Remove accumulated silt from all existing drainage.

SECTION II — STORM WATER MANAGEMENT
As part of the regulations set forth in the City of Wilmington Storm Water Management,
storm water detention is included with this proposed redevelopment.
2.1 STORM WATER DETENTION
In section 2.2 of this report you will see a summary of the runoff calculations for the 10- and
50-yr storm events. The runoff calculations are based on the rational method with
appropriate runoff coefficients that were calculated for the site. Runoff coefficients that
were use were 0.95 for impervious area and 0.2 for grass areas. .
Pond routing calculations were completed using the Chainsaw method. Detailed routing
results are located in the appendices of this report.
Storm pipe calculations for the run of pipes leading to the infiltration/detention basin were
conducted with StormCAD modeling software. Detailed model results are located in
Appendix G of this report. The results show that the 10-yr storm is contained in the
pipe/inlet system. In the 50-yr storm, the two upstream-most structures will flood;
however, overflow stormwater would be contained on the site parking area.

2.3 CONCLUSION
Storm water will be detained in the proposed detention pond and will reduce post
development flows to less than pre- developed conditions for the 10-year storm.
SECTION III — WATER QUALITY
The pollutant removal design standard of 85% removal of total suspended solids will be met
by use of an earthen infiltration basin. Stormwater from the site will be routed into the
infiltration basin. Stormwater from the first 1 inch of rainfall will infiltrate into the soil. The
earthen infiltration basin will be constructed on site, and also used for stormwater detention
(see previous section).
Infiltration tests conducted at the proposed infiltration basin location on the site indicated an
infiltration rate of approximately 16.6 inches per hour (see report included in the Appendix).
Based on the determination of Vincent Lewis of the Division of Water Quality, the seasonal
high water table is such that there will be a separation of approximately 2 feet between the
seasonal high water table and the bottom of the proposed infiltration basin.
The infiltration basin is designed to capture and infiltrate, at a minimum, the runoff from the
first 1 inch of rainfall. Stormwater will flow across parking areas, into inlet structures or
concrete flumes, and into the basin. Runoff in excess of the design volume of the basin will
flow over a weir into discharge piping, and flow through a 30-foot vegetated buffer prior to
entering the existing roadside stormwater drainage system.
Maintenance
1. After every runoff producing rainfall event and at least monthly, inspect the
infiltration/overflow/bypass structures for blockage.and deterioration and the
infiltration basin structure and system for erosion, trash accumulation,grass cover, and
general condition.
2. Repair eroded areas immediately, re-seed as necessary to maintain adequate vegetative
cover,mow vegetative cover to maintain a maximum height of six inches, and remove
trash and blockages as needed to maintain system performance.
3. Remove accumulated sediment annually or when sediment depth fills the sump in the
control manhole. Restore sump depth to original design depth. Removed sediment
shall be removed from the site and disposed of in an appropriate manner.

IV. INFILTRATION BASIN OPERATION AND MAINTENANCE AGREEMENT
1. After every runoff producing rainfall event and at least monthly inspect the infiltration system for erosion,:
trash accumulation, vegetative cover, and general condition.
2. Repair eroded areas immediately, re-seed as necessary to maintain adequate vegetative cover, mow
vegetated cover to maintain a maximum height of six inches, and remove trash as needed.
3. After every runoff producing rainfall event and at least monthly inspect the bypass, inflow and overflow
structures for blockage and deterioration. Remove any blockage and repair the structure to approved design
specifications.
4. Remove accumulated sediment from the pretreatment system and infiltration basin annually or when depth
in the pretreatment unit is reduced to 75% of the original design depth. The system shall be restored to the
original design depth without over-excavating. Over-excavating may cause the required water table
separation to be reduced and may compromise the ability of the system to perform as designed. Removed
sediment shall be disposed of in an appropriate manner and shall not be handled in a manner that will
adversely impact water quality (i.e. stockpiling near a stormwater treatment device or stream, etc.).
A benchmark shall be established in the pretreatment unit. The benchmark will document the original
design depth so that accurate sediment accumulation readings can be taken. The measuring device used to
determine the depth at the benchmark shall be such that it will give an accurate depth reading and not
readily penetrate into accumulated sediments.
When the design depth reads_0.5 feet in the pretreatment unit, the sediment shall be
removed from both the pretreatment unit and the infiltration basin.
5. If the Division determines that the system is failing, the system will immediately be repaired to original
design specifications. If the system cannot be repaired to perform its design function, other stormwater
control devices as allowed by NCAC 2H .1000 must be designed, approved and constructed.
I acknowledge and agree by my signature below that I am responsible for the performance of the five
maintenance procedures listed above. I agree to notify DWQ of any problems with the system or prior to any
changes to the system or responsible party.

Re: Infiltration Evaluation

ECS Project No. 22.12.427
Dear Mr.Blown;
ECS Carolinas, LLP (ECS) recently conducted an infiltration evaluation for the proposed
infiltration area at the proposed site at the intersection of Princess Plaee Drive and Market Street
in Wilmington,North Carolina. This letter,with attachments,is the report of our evaluation.
Field Investigations
On September 11,2006,ECS conducted an exploration of the subsurface soil and ground water
conditions at two requested locations shown on the attached Site Diagram. The purpose of this
exploration was to obtain subsurface information of the suitability of the in-place soils for the
Proposed infiltration area. We explored the subsurface soil and ground water conditions by,
advancing one hand auger boring into the existing ground surface at the two requested boring
locations. We visually classified the subsurface soils and obtained representative samples of
each soil type encountered. We also recorded the ground water level.observed at the time of the
hand auger boring. The attached Infiltration Evaluation Form provides a summary of the
subsurface conditions encountered at each hand auger boring location.
Ground water was encountered during our exploration at both test locations at a depth of 36
inches below the existing grade elevation. The seasonal high ground water level (SHWL) was
estimated to beat a depth of 30 inches for test location one and 24 inches for test location two
below the existing grade elevation.
We have conducted two infiltration tests near our hand auger borings to estimate the infiltration
rate for the subsurface soils. The infiltration tests were conducted at two feet above the SHWL
for both requested locations.

ECS Project No.22.12427
Field Test Results
At the first requested test location, the infiltration test was performed at 10 inches in grey fine
SAND and indicated an infiltration rate of 0.28 inches per minute(16.6 inches per hour). At the
second requested test location, the infiltration test was performed at 10 inches in grey fine
SAND and indicated an infiltration rate of 0.29 inches per minute(17.4 inches per hour).
Infiltration rates may vary within the proposed site due to possible changes in subsurface
conditions.

Brian,
The project,will require a modification to the permit, based on Dan's 9/7/07 email
to Cameron Weaver and Janet Russell, since changes are being made to the stormwater
system layout. The project would only involve a Plan Revision if there is: (a) no
increase to the permitted BOA; and (b) no change to the permitted stormwater system.
The Express program review fee for a high density application for a permit
modification is $4000, and the Plan Revision fee is $1000.
For a permit modification, please submit: (a) 1 completed original for - application
form and supplement(s) (supplements also need to be notarized) ; (b) 1 copy of
Narrative describing proposed project; (c) 1 PE-stamped & dated set of calculations
for revised BMP; (d) 2 sets of PE-stamped plans/details that describe proposed changes
to the previously-approved plans for the current permit, including any project area,
drainage area, and BMP layout changes; and (e) $4000 fee.
For a Plan Revision, please submit: (a) Cover letter and Narrative describing proposed
project; (b) 2 sets of PE-stamped plans/details; and (c) $1000 fee.

Janet,
The Express questionnaire is attached.
The infiltration system was approved under permit SW8 061115 but has
not
been constructed. The infiltration basin will remain in the same
location on the site, although the shape will be slightly modified.
The '
soils report/infiltration data was submitted with the approved
application. We will submit the same report with the application for
modification.
Let me know if there is additional information you need at this time,
and what the next step of the process will be.

Mr. Brown:
The Express Permitting Group is in receipt of the Request for Express
Permit Review for the stormwater plan modification for McDonald's. However,
we still need the Express questionnaire. We will consider your coversheet
"Memo" as the project narrative for this modification. I need to know if
the infiltration system is proposed,
approved but not constructed or existing. If this infiltration ( I
basin
is one that we will be reviewing in the modification, an infiltration
sheet must be submitted along with the supplemental information (i.e. II

Cameron and Janet:
You are probably well-familiar with this site by now, since it is just a couple of miles down the road from you,
and it was approved in January, and then modified in March. McDonald's and NCDOT have come to a new
agreement and arrangement on the driveway entrances, and this will cause a change to the impervious area of
the site and layout.of-the.stormwater system. Therefore, we need"to get ono` ther permit mmoaification-in the
works.
1___�.
I have attached an express coversheet to this email. We are currently revising/updating the plans.
Understanding the heavy workload in the Wilmington office, and also for our own convenience, we would like to
request to work with Paul Bartlett out of Raleigh. I want to go ahead and get this started, please let me know
the next steps that need to be taken.
Thanks,
Daniel Brown
