Subject: Additional Information
Stormwater Management Project No. SW8 950814
Kure Beach Village — Phase III
New Hanover County
Dear Ms. Lewis:
In response to your request for additional information regarding the
subject project, we are submitting the following information:
1. Since the project is a revision to the previously permitted SW8 940217
(Keys at Kure Beach), please use the previously submitted plans and
calculations for project No. SW8 950814 (Kure Beach — Phase III) as
revisions to SW8 940217.
2. An Operation and Maintenance Plan is unnecessary for Kure Beach Village
— Phase III since it was previously submitted for the Keys at Kure Beach.
3. A revised submittal form for The Keys at Kure Beach is enclosed. The
first column of the calculations section shows Keys at Kure Beach built —
upon area and the second column shows total built —upon area from both
projects draining to the pond. A revised submittal form for Kure Beach
Village — Phase III shows only built —upon information for that project.
On the form for Kure Beach Village — Phase III, the description of
stormwater treatment states that the previously permitted pond for The
keys at Kure Beach (SW8 940217) will be used.
4. The drop inlets are located within the street pavement with the back
of the inlets at the gutter line as stated in a note beside the drop
inlet detail on sheet #5.
5. A note on the plan (sheet #1) states, "All runoff from the tennis
court/recreation area must be directed to the stormwater pond.
6. The deed restriction will include the statement, "Drainage from all
impervious surfaces and lots shall be routed to the stormwater detention
pond by grading the front two—thirds of each lot to slope toward the

street, and/or using gutters on all structures to route flow to the
street, and/or providing swales to route rear and side lot drainage to
the street." (See deed restrictions section on Kure Beach Village —
Phase III submittal form).
7. A cul—de—sac detail is added to the plans.
8. The orifice size of 3.25" is corrected on the riser detail.
Enclosed are revised submittal forms for The Keys of Kure Beach (940217)
and Kure Beach Village (950814). Included are two (2) complete sets of
revised plans.
Please contact me if you have any questions.

Subject: ADDITIONAL INFORMATION
Stormwater Project No. SW8 950814
Kure Beach Village, Phase III
New Hanover County
Dear Mr. Hill:
The Wilmington Regional Office received a Stormwater Submittal for the Kure Beach Village,
Phase III on August 15, 1995. A preliminary review of that information has determined that the submittal
for the subject project is not complete. The following information is needed to continue the stormwater
review:
1. The submitted project is actually a revision to the previously permitted SW8 940217, so
revised plans and calculations must be submitted for 940217, showing the new design storage
elevations and design of the new pond. With your permission, I can use sheets 2 and 5 of
5 of the submitted plans and the submitted calculations as revisions to 940217.
2. An Operation and Maintenance plan has already been signed for the pond and it's drainage
piping. It is not necessary to do another.
3. A revised submittal form for 940217 must be done. The first column should contain the
Keys at Kure Beach built -upon areas, and the second column can be used to show the total
B/U area from both projects that will drain to the pond. Additionally, the 950814 submittal
form should contain only the information about the current project. In the description of the
stormwater treatment, say that the previously permitted pond for SW8 940217 will be used.

4. It appears from the plans that the drop inlets are located outside of the curb line. I can only
assume that the runoff will be captured by use of transitioning the curbing. Please provide
a detail.
5. Please provide elevations for the Recreation Area, or note on the plans that all runoff must
be directed to the pond.
6. Because the subdivision does not meet 30 % low density, this Office must be assured through
the use of recorded deed restrictions that all impervious areas will be picked up by the pond,
including all lot drainage. Options to ensure this include:
a. Require that 2/3 rds of the lot be graded to the street, or directed to the pond.
b. Require that gutters be used on all structures and directed to the pond.
C. Provide swales to carry the rear and side lot drainage to the pond.
7. Please add a cul-de-sac detail to the plans.
8. I am unclear as to the orifice size. The revised calculations use 3.25", but the plan detail
calls for 4". Please clarify.
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 6, 1995, or the submittal will
be returned as incomplete.
If you have any questions concerning this matter please feel free to call me at [phone].

form, and a (1) signed copy of the operation and maintenance plan.
Since the built —upon area exceeds 30 percent of total project area,
a detention pond will be used to treat runoff. An existing detention pond
serving The Keys of Kure Beach will be also be used for stormwater management
for Kure Beach Village — Phase III.

Stormwater runoff from the project will be retained in an existing wet
detention pond serving The keys of Kure Beach (Stormwater Permit No. SW8
940217).Since runoff from Kure Beach Village — Phase III will be added to
the runoff generated by The Keys of Kure Beach, modifications are necessary
to make the pond capable of storing the combined runoff generated by 1 inch
of rainfall from both projects.
The pond area required to remove 90% of total suspended solids was
calculated using the SA/DA Percentage Chart (see chart) for North Carolina
coastal regions.

Re: Request for Additional Information - Analysis of 1-inch Storm on Keys Pond
Kure Dunes, Phase IV, Stonnwater Project No. SW8 961234
New Hanover County, Dawson Engineering Project No. 9611
Dear Ms. Lewis:
3177 Wrightsville Avenue
Wilmington, NC 28403
[phone]
In response to your letter dated July 3, 1997, we have prepared the following calculations and analyses of the I -
inch storm on the Keys pond and the impact of the proposed Kure Dunes Phase IV pond discharging into the Keys
pond.
The DWQ regulations require the treatment of the first 1-inch of runoff from impervious areas. The volume of l-
inch runoff required for the Kure Dunes Phase IV project is 12,790 cubic feet and the volume of 1-inch runoff
required for the Keys and Kure Beach Village projects is 48,153 cubic feet. These volumes were determined
using the Schueler Method.
The first attachment is a copy of the "KURE BEACH VILLAGE - PHASE Bi Stormwater Detention Pond
Calculations" prepared by Mr. Joseph S. Hill, P.E. Mr. Hill uses a non -routing analysis to estimate that it will
take 3.9 days for the pond at the Keys to release the required 1-inch of runoff volume (56,974 cubic feet) stored in
the pond from Kure Beach Village and the Keys (see pages 1 and 5 of Mr. Hill's calculations). Based on field
topography survey of the constructed pond and using the Schueler Method, our non -routing analysis estimates it
will take 3.7 days to release the required 1-inch runoff volume (see attached "KEYS POND CALCULATIONS').
The effective storages were calculated from actual field survey data of the Keys pond.
We are proposing to discharge the outflow of the proposed Kure Dunes Phase W pond into the existing pond
serving Kure Beach Village and the Keys. To accurately model this situation, we have prepared manual
hydrogmphs of storms producing one -inch of runoff for Kure Dunes Phase W, and Kure Beach Village and the
Keys. The manual hydrographs produced are based on a quick 15 minute storm which is typical for our area.
The Kure Dunes Phase IV 15-minute storm was developed to produced 12,790 cubic feet of runoff. The peak
discharge was determined by dividing the volume (12,790 cubic feet) by 10 minutes to obtain 21.32 cfs. A
manual hydrograpb was produced to have a peak discharge of 21.32 efs at 5 and 10 minutes and 0 cfs at 0 and 15
minutes.
The same procedure was utilized for the Keys and Kure Beach Village projects. Based on Mr. Hill's calculations,
the impervious area for the Keys and Kure Beach Village projects total 13.32 acres of the total drainage area of
25.51 acre, or 52.2 % impervious. Based on the Schueler Method, the volume of runoff required to be stored and
released over a 2-5 day period is 48,153 cf.

REQUIRED STORAGE FOR 1-INCH OF RUNOFF FOR THE KEYS -POND: (use Schueler Method)
= 0.05 + 0.009,(1)
= 0.05 + 0.009(52.2) = 0.52
= (1")(0.52)(1/12)(25.51)(43,560)
= 48,153 CF
A peak discharge rate for a 15 minute storm was determined by dividing the volume (48,153 cubic feet) by 10
minutes to obtain 80.26 cfs. A manual hydrograph was produced to have a peak discharge of 80.26 cfs at 5 and
10 minutes and 0 cfs at 0 and 15 minutes.
In routing the storms, some assumptions were used:
1) The size of the orifice used was 3.25 inches (from Mr. Hill's calculations dated 8/14/97)
2) The crest elevation of the 36-inch riser is 16.9 (from survey data)
3) The orifice invert is elevation 14.40 (from survey data)
Please see the schematic diagram of the hydrographs. Numbers I through 7 refer to hydrographs previously
provided while hydrographs 8-12 and 13 & 14 are for the new calculations.
The first set of hydrograph calculations (STORMWATER CALCULATIONS FOR ROUTING I -INCH
RUNOFF FROM THE KEYS & KURE BEACH VILLAGE ONLY) refer to runoff from the 1-inch storm for
Kure Beach Village and the Keys. In referring to the hydrographs, hydrograph No. 13 is the 1-inch storm
hydrograph from Kure Beach Village and the Keys. Hydrograph No. 14 is the routed outflow hydrograph of the
Key's pond which indicates a maximum total storage volume in the pond of 48,039 cubic feet with a peak outflow
rate of 0.22 cfs and a peak stage elevation of 15.19 feet.
The second set of hydrograph calculations (STORMWATER CALCULATIONS FOR ROUTING 1-INCH
RUNOFF FROM KURE DUNES PHASE IV, THE KEYS & KURE BEACH VILLAGE) refer to runoff from
the 1-inch storm for Kure Dunes Phase IV, Kure Beach Village, and the Keys. In referring to the hydrographs,
hydrograph No. 8 is the 1-inch storm hydrograph for Kure Dunes Phase IV. Hydrograph No. 8 flows into No.
10, which is the Kure Dunes Phase IV pond (Reservoir No. 2). Hydrograph No. 9, which is the flow from the
Keys and Kure Beach Village, is then combined with the outflow of hydrograph No. 10 to form hydrograph No.
11. Hydrograph No. 12 is the routed outflow hydrograph of the Key's pond wluch indicates a maximum total
storage volume in the pond of 48,090 cubic feet with a peak outflow rate of 0.22 cfs and a peak stage elevation of
15.19 feet.
The routing method analyses indicate there is only a 0.04 ft difference in maximum pond elevation, a 0.02 cfs
difference in outflow at the end of 5 days and 51 cubic feet of extra storage volume in the Key's pond after the
Kure Dunes pond is allowed to discharge into the Key's pond. Therefore the impact of discharging the Kure
Dunes Phase IV pond outflow into the Keys pond will be insignificant.
We hope this clarifies the effect the Kure Dunes Phase IV pond has on the Keys pond. If you need additional
information please call.
Very truly yours,

Stormwater Project No. SW8 940217
The Keys at Kure Beach
New Hanover County
Dear Mr. Hill:
The Wilmington Regional Office received the revised Stormwater Submittal for the The Keys at
Kure Beach on April 4, 1995. A preliminary review of that information has determined that the submittal
for the subject project is not complete. The following information is needed to continue the stormwater
review:
/'1. North Carolina registered Professional Engineers seal on the calculations.
1/ 2. A revised submittal form, indicating the new impervious area numbers.
3. The calculations have been based on a "mean surface area" of 14.65.. You have not
provided this Office with the new permanent pool or storage elevations and surface areas
provided at those elevations. If the pond contours have not been revised since the last
submittal, then the volume provided in the pond, 30,700 cubic feet is deficient. The pond
is not designed to hold 36,428 cubic feet which you calculate as the required volume.
Your outlet structure detail, however, indicates an orifice invert of 14.35 and a top of riser .
at 14.95. If these are your new permanent pool and storage elevations, then please provide
the surface areas at each elevation, revise your pond contours to show the 14.35 and 14.95
contours, and calculate the volume provided in the pond between those contours.
4. The orifice calculation is still referencing the old 226,113 gallons of runoff volume. Please
revise to use the new figure of 272,481 gallons.

In response to your notice of violation dated March 3, 1995, we are
submitting three (3) copies of the revised stormwater plan and calculations
for The Keys of Kure Beach.
This plan shows revised building dimensions (see typical drawings of
2—unit and 4—unit buildings at northwest project corner) and building
locations. Changes to the outlet structure necessary to accommodate the
revised building layout are shown on the detail sheet.
The proposed "Plan of Action" is as follows:
1. Obtain approval of revised plans from N.C.D.E.M.
2. Perform necessary changes to detention pond outlet structure.
3. Obtain Engineer's certification.
Please call if you have any questions.
