Lot 19 Blue Cove
High Density Stormwater Project
New Hanover County
Dear Mr. Fort:
The Wilmington Regional Office received a complete Stormwater Management Permit
Application for Lot 19 Blue Cove on June 10, 2003. Staff review of the plans and specifications
has determined that the project, as proposed, will comply with the Stormwater Regulations set
forth in Title 15A NCAC 2H.1000. We are forwarding Permit No. SW8 030231 dated June 13,
2003, for the construction of Lot 19 Blue Cove.
This permit shall be effective from the date of issuance until June 13, 2013, and shall be subject
to the conditions and limitations as specified therein. Please pay special attention to the
Operation and Maintenance requirements in this permit. Failure to establish an adequate system
for operation and maintenance of the stonnwater management system will result in future
compliance problems.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the
right to request an adjudicatory hearing upon written request within thirty (30) days following
receipt of this permit. This request must be in the form of written petition, conforming to
Chapter 150B of the North Carolina General Statutes, and filed with the Office of Administrative
Hearings, P.O. Drawer 27447, Raleigh, NC 276 1 1-7447. Unless such demands are made this
permit shall be final and binding.
If you have any questions, or need additional information concerning this matter, please contact
Laurie Munn, or me at [phone].

actual impervious%and permanent pool depth. Linear interpolation should be employed to determine the correct value for non-
standard table entries.
2. In the 20 coastal counties, the requirement for a vegetative filter may be waived if the wet detention basin is designed to provide
90%TSS removal. The NCDENR BMP manual provides design tables for both 85%TSS removal and 90%'I'SS removal.
Ill. REQUIRED ITEMS CHECKLIST

c. The temporary pool controls runoff from the design storm event.
_ CIL— d. The temporary pool draws down in 2 to 5 days.
e. 1f required, a 30-foot vegetative filter is provided at the outlet(include non-erosive flow
calculations).
C fY_ f. The basin length to width ratio is greater than 3:1.
g. The basin side slopes above the permanent pool are no steeper than 3:1.
h. A submerged and vegetated perimeter shelf with a slope of 6:1 or less (show detail).
i. Vegetative cover above the permanent pool elevation is specified.
G j. A trash rack or similar device is provided for both the overflow and orifice.
�( ( k. A recorded drainage easement is provided for each basin including access to nearest right-
of-way.
GnC 1. If the basin is used for sediment and erosion control during construction, clean out of the
basin is specified to be performed prior to use as a wet detention basin
m. A mechanism is specified which will drain the basin for maintenance or an emergency.
III. WET DETENTION BASIN OPERATION AND MAINTENANCE AGREEMENT
The wet detention basin system is defined as the wet detention basin, pretreatment including forebays and the
vegetated filter if one is provided.
This system (check one) ❑ does X does not incorporate a vegetated filter at the outlet.
This system (check one) ❑ does X does not incorporate pretreatment other than a forebay.
Form SWU-102 Rev 3.99 Page 2 of 4

Maintenance activities shall be performed as follows:
I. After every significant runoff producing rainfall event and at least monthly:
a. Inspect the wet detention system for sediment accumulation, erosion, trash accumulation,
vegetated cover, and general condition.
b. Check and clear the orifice of any obstructions such that drawdown of the temporary pool occurs
within 2 to 5 days as designed.
2. Repair eroded areas immediately, re-seed as necessary to maintain good vegetative cover, mow vegetative
cover to maintain a maximum height of six inches, and remove trash as needed.
3. Inspect and repair the collection system (i.e. catch basins, piping, swales, riprap, etc.) quarterly to
maintain proper functioning.
4. Remove accumulated sediment from the wet detention basin system semi-annually or when depth is
reduced to 75% of the original design depth (see diagram below). 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 wet detention basin or stream, etc.).
The measuring device used to determine the sediment elevation shall be such that it will give an accurate
depth reading and not readily penetrate into accumulated sediments.
When the permanent pool depth reads 4.5 feet in the main pond, the sediment shall be removed.
When the permanent pool depth reads 2.25 feet in the forebay, the sediment shall be removed.

Dear Laurie:
In response to your correspondence dated May 1, 2003, we offer the following:
✓l. A note has been included to route roof drains to be proposed pond.
2. Additional spot elevations have been provided to show runoff enters the pond
and not the wetland areas. Curb has also been provided at low point to force
runoff into flume.
3. Existing contours have been provided. Existing property line ditches keep off-
site runoff from reaching the proposed site.
4. The wetland consultant is applying for all necessary permits.
5. Please find enclosed a revised page 2 of the application with correct numbers.
6. We understand your concern of the wetland areas. The wetland consultant is
working with the necessary agencies for approval of the proposed plan. An
upland area does separate the proposed pond from the wetlands. The existing
elevations within the wetland area will not allow the proposed pond to work as
designed, therefore direct discharge to this area is not designed. We have
provided an emergency spillway that in big storms will recharge the area in
question.
Please review for approval and contact us with any questions, comments or if you
need additional information. Thank you.
Sincerely,
Tripp Engineering, P.C.

Subject: REQUEST FOR ADDITIONAL INFORMATION
Stormwater Project No. SW8 030231
Lot 19 Blue Cove
New Hanover County
Dear Mr. Fort:
The Wilmington Regional Office received a Stormwater Management Permit Application for Lot
19 Blue Cove on February 27, 2003. 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 show location of roof drains. All roof drains must drain to the pond.
2. Please add more spot elevations. Since no curb & gutter is on-site, additional spot
elevations are needed to show that all run-off enters the pond and that none drains to the
wetlands or drains off=site wit'-out being treated.
3. Please show some existing contours to verify that no offsite drainage is coming on-site.
4. It appears that a small area of wetlands will be filled. Please notify Noelle Lutheran of
this impact. I do not believe that any permits are necessary, but site likes to be informed
even when a permit is not required.
5. FYI, the BUA is listed as 52,530 ft2, but the sum Js actually 52,540 ft2. I have made the
change to the application.
6. The proposed design will no longer allow runoff into the wetlands. Also, I am concerned
that the pond may become part of the wetlands. Please consider constructing a berm
around the pond,and using a pipe to convey water from the forebay to the main pond.
Move the outlet control structure to discharge into the wetlands. This will serve as a
recharge to the wetlands. Then, let the wetlands discharge across the berm from the
forebay to the wetlands. I have attached a drawing to better explain.

The construction of any impervious surfaces, other than a construction entrance under an
approved Sedimentation Erosion Control Plan, is a violation of NCGS 143-215.1 and is subject to
enforcement action pursuant to NCGS 143-215.6A.
Please reference the State assigned project number on all correspondence. Any original
documents that need to be revised have been sent to the engineer or agent. All original documents must be
returned or new originals must be provided. Copies are not acceptable. If you have any questions
concerning this matter please feel free to call me at(910) 395-3900.

Stormwater Narrative
Lot 19 Blue Cove
New Hanover County, NC
Lot 19 Blue Cove is an existing vacant lot within a commercial subdivision. The lot is
proposed as high density development to be treated by wet detention. A proposed 16,800
sf building with 17,340 sf of asphalt parking and access, 16,770 sf of gravel parking, and
1,630 sf of concrete sidewalks create a total of 52,530 sf of impervious area.
Runoff from this site will be treated by wet detention designed for the V requirement as
well as the County's 25-year pre-post requirement. Outflow will be routed to Smith
Creek, classification C-SW.
