Linda,
I received you letter about Kure Dunes. I see that I did double count
some of the lots. I would like to leave the pond calculations the way
they are and just let the pond be slightly oversized for the amount of
imperviousness that drains to the pond. Let me know if this would be
O.K. I will have the breakdown of the lots with the allowable
built -upon area in square feet to you the first of next week.
Thanks....

REQUEST FOR ADDITIONAL INFORMATION
Stormwater Project No. SW8 961234 Modification
Kure Dunes Phase IV
New Hanover County
Dear Mr. Hargrove:
The Wilmington Regional Office received previously requested information for the modification to
the Stormwater Management Permit Application for Kure Dunes Phase IV on May 15, 1998. 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 Division no longer allows lots to be restricted on a percentage basis. It is too confusing
to the buyer and for us to keep track of. Please provide an attachement listing each lot by
number and it's allowable built -upon area in square feet. This listing will be required to be
part of the recorded deed restrictions for the subdivision.
2. You have allowed for 38 on -site lots in the Pond design, however, only 32 and a half lots
actually drain to the pond. Four and a half lots drain to the recharge trench, and one drains
into the Phase II pond, which is now being filled in, and the runoff will be treated in the
Beachwalk pond. You're essentially accounting for 5 and a half lots twice, which isn't
necessary.

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 August 9, 1998, or the application will be
returned as incomplete. The return of a project will necessitate resubmittal of all required items, including
the application fee.

STORMWATER OPERATION AND MAINTENANCE PLAN
FOR
KURE DUNES HOME OWNER'S ASSOCIATION, INC.
KURE BEACH, NORTH CAROLINA
1. The owner will be responsible for the proper operation and maintenance of the
stormwater collection and treatment facilities.
2. The collection system will be inspected monthly by the owner to identify
malfunctioning catch basins and drainage pipes. The collection system will be kept
relatively clear of debris and sediment. The stormwater system shall be kept in good
working order. Any malfunctioning component shall be repaired/replaced per approved
plans as necessary to assure proper operation of the system.
3. The treatment facilities consist of one (1) stormwater pond and outlet control. This
facility will be inspected twice a year by the owner to determine the mean depth of the
pond and identify any malfunctions. The mean depth of the pond, under normal
conditions, shall be 6.0 feet. The owner will remove the sediment from the pond if the
mean depth is determined to be less than 4.5 feet and will correct malfunctions when
necessary.
4. The outlet structure, orifice, and sideslopes will be inspected immediately after every
runoff producing rainfall event. Any debris observed on the orifice and outlet structures
will be removed. Eroded areas will be repaired and reseeded immediately after a rainfall
event.
5. A permanent stand of grass shall be maintained at all times. Mowing during the
growing season will be done as needed, otherwise, the grass height will not exceed 6"

Dear Ms. Lewis:

Since receiving your comments in a letter dated April 2, 1998, Kure Beach
Associates has decided to revise the layout of the Kure Dunes Phase IV
development into single family lots. The enclosed revised permit application
reflects the changes to the plan in regard to imperviousness. The pond depth
and the forebay depth have been modified to reflect the increase in impervious
area. The following information is provided in response to your previous letter:
1) A road detail has been provided on sheet C-5A.
2) The original submittal for the impervious area for the roads was
incorrect. When the permit was revised, the error was found and
corrected.
3) Since the amount of impervious area has increased due to the changes,
the 1-inch storage level has increased and the change in the
calculations is shown on sheet C-1 of the plans.
4) The pond will be located in a recorded easement. A homeowner's
association will be responsible for the pond.
5) The increase in the pond has not affected the downstream Key's pond
for the 1-inch storm. The orifice size remains to be 2 inches.
Two sets of revised calculations are provided for the pond. The %
imperviousness increased to 54.4%. The single-family lots will be allowed an
imperviousness up to 60%.

Kure Dunes Phase IV Modification
New Hanover County
Dear Mr. Hargrove:
The Wilmington Regional Office received a Stormwater Management Permit Application for Kure
Dunes Phase IV Modification on February 20, 1998. 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. Please add a road detail.
2. Why has the total amount of roads been reduced almost a thousand square feet? It appears that
the roadway has not changed from the last submittal, however, since no detail was provided,
I cannot verify this. Since the amount of road into the recharge system has not been increased
by a like amount, it is unlikely that drainage areas have been altered.
3. The calculations report an area of 10,439 square feet at elevation 18.15. This is smaller than
the permanent pool area reported. Please revise.
4. Locate the pond in a recorded access/drainage easement.
5. Has the increase in this pond affected the downstream Keys pond?

Dear Ms. Lewis: PROJ n 560-MOlZ34-
The plans for Kure Dunes Phase IV have been modified slightly to add several
townhomes and move the recreational area. The proposed plan now includes
a clubhouse with a pool. The percent imperviousness changed from 44.0 % to
51.0%. The calculations have been modified to reflect the changes in the
depth of the pond and the inverts associated with the outlet structure of the
pond.
