I. Monthly, or after every runoff producing rainfall event, whichever comes first:
A. Inspect the trash rack; remove accumulated debris, repair/replace if it is not functioning.
B. Inspect and clear the orifice of any obstructions. If a pump is used as the drawdown
mechanism, pump operation will be checked. A log of test runs of the pump will be kept
on site and made available to DWQ personnel upon request.
C. Inspect the pond side slopes and grassed inlet swales; remove trash, and repair eroded areas
before the next rainfall event.
D. If the pond is operated with a vegetated filter, the filter will be checked for sediment
accumulation, trash accumulation, erosion and proper operation of the flow spreader
mechanism. Repairs/cleaning will be done as necessary.
II. Quarterly (Four times a year):
A. Inspect the collection system (ie. catch basins, piping, grassed swales) for proper
functioning. Accumulated trash will be cleared from basin grates, basin bottoms, and piping
will be checked for obstructions and cleared as required.
B. Pond inlet pipes will be checked for undercutting. Riprap or other energy dissipation
structures will be replaced, and broken pipes will be repaired.
III. Semi-annually (twice a year):
A. Accumulated sediment from the bottom of the outlet structure will be removed.
B. The forebay depth will be checked at various points. Sediment removal is required when the
depth is reduced to 75% of the original forebay design depth of_ -_'.
C. Grassed swales, including the vegetated filter if applicable, will be reseeded twice a year as
necessary.

POND MAINTENANCE REQUIREMENTS
PAGE 2
IV. Annually (Once a year):
A. The pond depth will be checked at various points. Sediment removal is required when the
depth is reduced to 75% of the original design depth or Y, whichever is greater. Design
depth is'K 175', measured vertically from the orifice down to the pond's bottom.
Sediment must be removed to at least the original design depth. �K K,p k_ m2X.
V. General: d0h is
A. Mowing of the side slopes will be accomplished according to the season. Maximum grass t
height will be 6".
B. Cattails are encouraged along the pond perimeter, however they will be removed when they
cover more than 1/2 the surface area of the pond. The best time to cut them is at the end of
the growing season, in November. Environmentally sensitive chemicals for use in killing
cattails can also be used. Contact your nearest Agricultural Extension Agent.
C. The'orifice/pump is designed to draw down the pond in 2-5 days. If drawdown is not
accomplished in that time, the orifice will be replaced with a larger or smaller orifice. Slow
drawdown may be attributed to a clogged system. The source of the clogging will be found
and eliminated.
D. All components of the detention pond system will be kept in good working order. Repair
or replacement components will meet the original design specifications as per the approved
stormwater plan. If previously approved components are determined to be ineffective, the
component must be redesigned and/or replaced.
VI. Special Requirements:
I Gregory M. Duggan,Asst. Vice President , hereby acknowledge that I am the financially
(please print or,type name clearly)
responsible party for maintenance of this detention pond. I will be responsible for the performance of the
maintenance as outlined above, as part of the Stormwater Management Permit received for this project.

RE: Mill Creek- Phase II
To follow up on our earlier letter of October 20, the drawings have been
completed and are attached.
Pond A has the berm top reduced to 5 feet wide. The surface area at the
permanent pond elevation of 25 feet is 2,022 square feet as taken off by ACAD. The
required calculated surface area is 2,086 square feet, which is a difference of 64 square
feet. Since the volume for a 1-inch storm event is much in excess of that required, the
system should be adequate for treatment of the runoff.
To cut down on waste of paper, we have included only the changed sheets (C--1,
C-2, and C-2A). If these changes are acceptable, please call and we will make
additional copies and bind them into complete sets.

TO: Linda Lewis OCT 2 1 1Q.07
19Y;
RE: Mill Creek
_ C
As a quick response to your latest memo, we provide herein our comments to
the items you mentioned and will follow up with drawing changes.
1. It was our impression that you wanted the scaled pond layouts so that you could
more easily determine the overall dimensions. It is still best to use the site map
to see where the location of the weir is located.
2. The section has been deleted.
3. The terminology can be changed. We will change the upper elevation to the
terminology indicated in your October 17 fax.
4. The drawing was used for a take-off of the forebay for Pond B and the area was
1,681 square feet. The calculations were based on this data. Later, it was
found that the vegetative filter slope of 1:6 was used in the forebay. This was
changed back to the 1:3 slope, which gave more volume in the pond. The
surface area at Elevation 25 is 4,485 square feet instead of 1,681 square feet.
5. We will refrain from listing the "greenspace acreage" on the form. We use it to
assist us in total acreage calculations. We have never counted greenspace as
impervious acreage in our calculations.
6. The orifice size has been clarified.
7. The layout for Pond A has been revised.
8. The calculations are sealed.

Mill Creek Phase II
New Hanover County
Dear Mr. Butler:
The Wilmington Regional Office received previously requested information for the Stormwater
Management Permit Application for Mill Creek Phase II on October 7, 1997. This review was done in order
to determine if the information requested concerning the surface areas and volumes in the ponds was
provided for the ultimate purpose of releasing the site to get a building permit. The following information
is needed to continue the stormwater review:
1. The new scaled pond layouts show neither the grading associated with the 5' forebay weir nor
the location and elevation of the weir.
f2. Delete the pond section detail on sheet C-2. It no longer is valid.
3. What you refer to as the "Top of the Permanent Pool" is misleading. Please refer to it as the
design storage elevation, or the temporary pool elevation.
4. The surface area provided at elevation 25 in the forebay is significantly greater than the 1,681
square feet you report in the calculations. Please look at your pond layout dimensions again
and check.
5. Greenspace is not impervious and should not be listed on the application as impervious area.
6. The orifice in Pond B as sized in the calculations (2") does not correspond to the orifice size
noted on the outlet detail (2.75"). Please clarify and revise.

calculations, is 2,086 square feet. According to the pond layouts provided, the surface area
at 25 scales 857 square feet. Please revise.
f8. Please seal the calculations.
Please note that this review does not encompass all the information requested on September 17, 1997.
Additional information may be requested at the time that submittal is reviewed. The requested information
should be received by this Office prior to November 17, 1997, or the application will be returned as

Re: Mill Creek- Phase II
Dear Linda:
We have highlighted on the plans several items mentioned in your review. The
parking areas are designed to City of Wilmington standards. The stall length and
width appear in the detail. The length is on the sheet that gives the number of spaces,
which is needed for the City to ascertain a total parking space count. The aisle width
also comes from the City standards, is 22 feet wide, and is also shown in the detail.
The parking spaces also scale 22 feet.
Enclosed are additional plans of the typical footprint of the buildings.
For the ponds we have enlarged the scale. For easier construction ion the field
the vegetated area is 12 feet wide. The surface areas of both ponds for main pond and
forebay are shown in the calculations.
Sincerely yours,

Mill Creek Apartments Phase II
New Hanover County
Dear Mr. Butler:
The Wilmington Regional Office received a Stormwater Management Permit Application for Mill
Creek Apartments Phase II on August 20, 1997. A preliminary review of that information has determined
that the application is not complete. The following information is needed to continue the stormwater review:
1. The numbers on the application are unreadable due to the amount of white-out used. Please
redo the first page of the application form. While you're redoing, how about combining
drainage areas B and C together to form the Pond B drainage area.
2. Where on the plans do you show the parking space length and aisle width?
3. Does the 22' road section on Sheet C-4A apply to the parking lot aisle?
4. The typical building footprint you provided is not completely dimensioned..
5. Please delineate and label the permanent pool and design pool contours. This means that you
must show on sheet C-1 or C-3A the pond's contours in correct relationship to each other
based on the section provided, ie., the whole contours below 25 are 2' apart, the distance
from 25 to 26.67 is 10' (6:1 shelf) and the whole contours from 26.67 to 28 are 3 feet apart.
Based on what I see on the plans, this hasn't been done.

----------------------------------------------
/6. The dimensions of the permanent pool at elevation 25 must be provided. The dimensions are
given for each side of the figure created by the permanent pool contour. Using the pond
section to provide dimension information does not adequately convey the requirements. Many
engineers find it easy and less confusing to provide a to scale detail on the plans of the pond
with just the bottom, permanent pool, end of shelf, and design pool contours drawn.
Dimensions for the permanent pool are also provided on the detail. Remember to include the
forebay as part of the permanent pool. It isn't necessary to treat the forebay a separate
dimension.
✓ 7. Please list the surface area provided at elevation 26.67, the end of vegetated shelf, for both
ponds. Due to the methodology the State uses to calculate volume, it is necessary to have the
area at that elevation where the slope changes from 6:1 to 3:1. I am unable to duplicate the
volumes you come up with based on the areas shown in contour on the plans.
Please note that this request for additional information is in response to a preliminary review. The
requested information should be received by this Office prior to October 17, 1997, or the application will
be returned as incomplete. The return of a project will necessitate resubmittal of all required items, including
the application fee.

Dear Ms. Lewis:
We have met with the City and Owner on the stormwater plan and revised
sheets are attached. The following information/explanation are provided.
1 The finished floor elevations and spot elevations in the parking area are shown.
2. Inverts to the catch basins and pipe schedule have been added. They were taken
from the data calculated for the County erosion control permit.
3. A signed Operation&Maintenance Plan is enclosed.
4. Sheet C-0 has the wetlands delineated. We are keeping construction out of
those areas.
5. The site plan contains the dimensions of the drives and parking areas. The
detail sheet has dimensions for the roads and sidewalks.
6. Enclosed is a typical building footprint. No outside patios (wood or concrete)
are proposed. Our original calculations had a typical unit at 0.27 acre, whereas
the average unit is 0.29 acre. Revisions in the calculations have been made.
7. Roof downspouts are being determined by the Architect and have not
been completed. We have added a note to our drawings that they are to
be connected to the stormwater system or to swales that go to the system.

8. The drainage area(three total) is shown on a separate sheet. We further
separated it into sub-areas for flow to the individual inlets. Each inlet has its
own catchment area which determined the pipe sizing.
9. The outlets to Pond B are shown.
10. The slope of the permanent pond is now 3:1.
11. The forebay has been made shallower and contains 20 percent of the flow plus
some for sediment accumulation.
12. The labeling of the permanent pool and other elevations can best be seen in the
sections on Sheet C-2.
13. The dimension on the permanent pool contour is provided for Elevation 30.0.
14. The bottom elevation on the sections are shown on C-2.
15. A plan of the revised collection system areas with the building surface areas are
enclosed. We have added the ponds to the collection systems. The composite
"C" factor for Area 1 and Pond 1 is 0.62. The combined Areas B and C with
Pond B is 0.64. We could decrease the C factor by adding the stormwater
recharge areas between Areas B and C and include the wetland areas, but prefer
to consider only the areas flowing to the ponds. The ponds are larger than what
the data shows is required.
16. We will use the volume between Elevations 25 and 28 as the volume stored,
combining the forebay with the permanent pond. The volume above 28 is not
considered.
Please let us know if you have any questions.

11. Provide a forebay detail or incorporate one into the pond section. The forebay is shallower than the main
pond, and only needs to be large enough to accomodate 20% of the volume of the first inch. Overly large
forebays detract from the functioning of the pond. Label the bottom elevation, slopes, and the elevation
of the weir between the pond and the forebay.

V,'14. Add the bottom elevation to the pond section detail, and note the required minimum 3:1 slopes above
permanent pool,
15. The percent impervious of the site does not equate to the ECA divided by the total site area. Please
revise your calculations to accurately reflect this. Depending on the Y_CA value, the pond size you end
up with could be much smaller than required, or slightly larger than required.
16. The orifice size is based on the actual volume stored above the permanent pool to the design pool
elevation. I believe you have specified elevation 28 as the design pool for both ponds.
17. Provide the design information for each pond in it's own column on the application. Split up the
"Breakdown" section as well.
Please note that this request for additional information is in response to a preliminary review. The requested
information should be received by this Office prior to July 18, 1997, or the application will be returned as incomplete.
The return of a project will necessitate resubmittal of all required items, including the application fee.

Dear Ms. Lewis:
Enclosed are three sets of plans, specifications, and a set of calculations for the
project. The application and a check for $385 is also enclosed.
This is the project on which we met with you in January or February. We will
not be contributing flow to the stream area in the center of the project and have not
used this acreage in the flow calculations. Basically, the "disturbed area" used for
erosion control is the same area used for stormwater.
The City wants to review this project after you complete your review. Please
advise if you need additional information.

SECTION 02110 - SITE CLEARING
1. GENERAL REOUIREMENTS:
This section covers the furnishing of all labor, materials, equipment and services required
for clearing and grubbing within the clearing limits shown on the drawings as specified
herein. Within established public rights of way (roads and streets) only such growth and
trees will be cleared as is required to construct the pipeline. Where monumental trees are
located and designated, no cutting of any part of the tree or principal roots will be allowed
and the pipe will be installed by tunneling under the tree. Trees which are 24" diameter
B.H. will be considered as monumental trees unless designated for removal by the
Engineer. Where new rights of way are acquired to construct the pipeline, the entire width
of the right of way will be cleared except for monumental trees. Within the clearing limits
of the pumping station sites, the area will be cleared and grubbed.
2. CLEARING:
Clearing shall consist of the felling and cutting of trees into sections and the satisfactcny
disposal of the trees and other vegetation designated for removal, including down timber,
snags, brush, and rubbish occurring within the areas to be cleared. Trees, stumps, roots,
brush, and other vegetation in areas to be cleared shall be cut off, flush with or below the
original ground surface, except such trees and vegetation as may be indicated or directed
to be left standing. Clearing shall so include the removal and disposal of structures that
obtrude, encroach upon, or otherwise obstruct the work. In areas designated as selective
clearing limits, all trees 6 inches and larger shall remain. All other vegetation shall be
removed as specified hereinbefore.
3. GRUBBING:
Grubbing shall consist of the removal and disposal of stumps and roots larger than 3 inches
in diameter, and matted roots within the clearing limits shown on the drawings. This
material, together with logs and other organics or metallic debris not suitable for
foundation purposes, shall be excavated and removed to a depth of not less than 18 inches
below the original surface level of the ground in areas indicated. Depressions made by
grubbing shall be filled with suitable material and compacted to make the surface with the
original.adjacent surface of the ground.
4. DISPOSAL OF CLEARED AND GRUBBED MATERIAL:
All trees, branches, snags, brush, stumps, etc., resulting from the clearing and by grubbing
shall become the property of the Contractor and shall be disposed of by burning, removal
from the property or a combination of both. All burning done, if any, shall comply with
applicable State and local ordinances. The value of merchantable timber, if any, shall be
reflected in the bid price for clearing and grubbing.
4465.02 (041697) SITE CLEARING 02110-1

5. PAYMENT:
No separate payment will be made for clearing of trees less than 8" diameter B.H. or
smaller brush. Payment for clearing trees larger and for clearing of rights of way and
clearing and grubbing of station sites will be at the unit price schedule in the Proposal.

SECTION 02270 - EROSION AND SEDIMENTATION CONTROL
1. GENERAL REQUIREMENTS:
The work includes all measures necessary to effectively control erosion on the construction
site and prevent sediment-laden run-off from leaving the construction site.
2. CONTRACTOR'S RESPONSIBILITY:
The Owner has submitted an erosion control plan to the proper authority and received a permit
which is included in these specifications following this section. The Contractor agrees to all
of-the conditions of the permit and the Contractor shall be responsible for prevention of
damage to properties outside the construction limits from siltation due to construction of the
project. The Contractor will assume all responsibilities to the affected property owners for
correction of damages which may occur. The Contractor further agrees to assume all
responsibilities for all fines or damages accessed against the Owner by any regulatory agency
or individual due to lack of proper erosion and sediment control during construction. The
Owner reserves the right to withhold a portion of the Contractor's payment requests sufficient
to pay the assessments.
3. MINIMUM AREAS TO BE DISTURBED:
A. Only those areas necessary for timely and proper completion of the project shall be
stripped of native vegetation.
B. No land disturbing activity shall be permitted in proximity to a natural watercourse
without a buffer zone along the margin of the watercourse of sufficient width to confine
visible siltation within the 25 percent of the buffer zone nearer the land disturbing
activity.
C. The angle for graded slopes and fills shall be no greater than the angle which can-be
retained by vegetative cover or other adequate erosion control devices or structures.
Slopes left exposed will, within 30 working days of completion of any phase of grading,
be planted or otherwise provided with ground cover, devices, or structures sufficient to
restrain erosion.
D. Whenever land disturbing activity is undertaken on a tract comprising more than one
acre, if more than one contiguous acre is uncovered, a ground cover sufficient to restrain
erosion must be planted or otherwise provided within 30 working days on that portion
of the tract upon which further active construction is not being undertaken.
4465.02 (041697) EROSION AND SEDMIENTATION CONTROL 02270-1

4. METHODS TO BE USED - EROSION CONTROL SCHEDULE REQUIRED:
Any accepted erosion sedimentation control measures may be used, at the Contractor's option,
including and in addition to specific measures prescribed in the project plans and elsewhere
in these specifications. Methods which may be used include, but are not limited to,
vegetation, berms, silt fences or silt basins. The Contractor shall program and submit to the
Engineer prior to beginning construction an erosion control schedule outlining measures to
be taken for positive control of erosion and sedimentation during construction.
5. PLACEMENT OF SEDIMENT CONTROL DEVICES:
All devices (silt fences, silt basins, etc.) for sediment control shall be constructed prior to
beginning clearing and grubbing on the site.
6. MOINTENAN E OF SEDIMENT CONTROL DEVICES:
All devices for sediment control shall be maintained in proper working order for the duration
of the project.
7. SCHEDULING OF WORK:
Clearing and grubbing shall be scheduled and performed in such a manner that subsequent
grading operation and erosion control practices can follow immediately thereafter.
Excavation, borrow, and embankment operations will be conducted such that cuts and fills
will be completed to final grades in a continuous operation. All construction areas not
otherwise protected shall be planted with permanent vegetative cover in accordance with
Section 02930 (Establishing Vegetation) of the Specifications within 30 working days after
completion of active construction.
8. TEMPORARY SUSPENSION OF WORK:
If any earthwork is to be suspended for any reason whatsoever for longer than 30 calendar
days, the areas involved shall be seeded with temporary vegetative cover or otherwise
protected against excessive erosion during the suspension period. Suspension of work in any
area of operation does not relieve the Contractor of the responsibility for the control of erosion
in that area.
9. REMOVAL OF SEDIMENT CONTROL DEVICES:
Near the completion of the project or upon instruction by the Engineer, the Contractor shall
dismantle and remove silt fences and fill silt basins used for sediment control during
construction and dress up and seed the area to give a pleasing appearance.
4465.02 (041697) EROSION AND SEDIMENTATION CONTROL 02270-2

10. ADDITIONAL MEASURES:

on the construction site despite the application and maintenance of prescribed protective
measures, the Engineer may require the Contractor to take additional protective measures.
11. DUST CONTROL:
A. The Contractor shall control dust throughout the life of the project within the project area
and at all other areas affected by the construction of the project, including, but not
specifically limited to,unpaved secondary roads, haul roads, access roads, disposal sites,
borrow and material sources, and production sites. Dust control shall not be considered
effective where the amount of dust creates a potential or actual unsafe condition, public
nuisance, or condition endangering the value, utility, or appearance of any property.
B. The Contractor will not be directly compensated for any dust control measures
necessary, as this work will be considered incidental to the work covered by the various
contract items.
12. PAYMENT:
All work included under this section shall be considered incidental to other work being paid
for by the various items in the contract. No special payment shall be made for erosion and
sedimentation control measures during construction.

Subject: REQUEST FOR STORMWATER MANAGEMENT
PERMIT APPLICATION
Mill Creek Phase H
Stormwater Project No. SW 970521
New Hanover County
Dear Mr. Duggan:
On May 12, 1997, the Wilmington Regional Office received a copy of the Sedimentation Erosion Control Permit
Application for Mill Creek Phase H. The North Carolina Administrative Code requires any project that must receive either
a Sedimentation and Erosion Control Plan permit and/or a CAMA major permit to apply for and receive a Stormwater
Management Permit by the Division of Water Quality. Any construction on the subject site, prior to receipt of the required
permit, will constitute a violation of 15A NCAC 2H.1000 and may result in appropriate enforcement action by this Office.
Either a Stormwater Permit Application Package including 2 sets of plans, completed application form, fee, and
supporting documentation, or a written response regarding the status of this project and the expected submittal date must
be received in this Office no later than June 12, 1997, or the subject project file will be closed and construction may
experience a subsequent delay. If you have any questions, please call me at(910)-395-3900.
Sincerely,
Linda Lewis
Environmental Engineer
