Brunswick County .
Dear Mr. Saucier:
The Wilmington Regional Office received a Stormwater Management Permit Application for
SPEC - Leland on November 30, 2005. A preliminary review of that information has
determined that the application is not complete. The following information is needed to
ntinue the stormwater review:
1. Please clarify the impervious area entries for "Parking" (32,772 sf) and "Other on -
site" (2,408 sf) in Section 111.6 of the application. Drawing 3.0 lists 22,772 sf and
41
2,480 sf, respectively. The total of 42,658 sf on the application appears correct.
2. Please label Swale #1 on Sheets #5 and #6.
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 December 30, 2005, or the
application will be returned as incomplete. The return of a project will necessitate resubmittal of
all required items, including the application fee.
If you need additional time to submit the information, please mail or fax your request for a time
extension to the Division at the address and fax number at the bottom of this letter. The
request must indicate the date by which you expect to submit the required information.
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.

LELAN D, NC
This + 3.94 acre site is located at the end of Thomas Garst Lane in the Town of Leland.
This project consists of clearing, grading, and installation of infrastructure for a proposed
12,100 SF Daycare Facility. The proposed disturbed area for this project is + 3.5 acres
and the total amount of impervious area compared with the total project boundary is
24.85%. The erosion control plan identifies the appropriate measures to be implemented
for erosion control purposes during construction of the infrastructure associated with this
development.
The project is approximately 3.94 acres in size with an ultimate proposed disturbed area of
3.5 acres. The site is mostly open and drains from the west to the east at slopes of 3%
SOI LS
The soils onsite consist of Mandarin Fine Sand and Muckalee Loam series soils. The
Mandarin series soils consist of somewhat poorly drained, flat sandy soils with a
Hydrologic soils grouping of C. The Muckalee series soils consists of poorly drained soils
on low flood plains with a Hydrologic soils grouping of D.
STORM DRAINAGE
The primary stormwater measure for this project is a grassed swale located in the southern
portion of the site. The stormwater will be conveyed via overland sheet flow to the
proposed swale. Roof drains will also splash block runoff to the rear of the site.
Calculations and a cross section of the grassed swale are provided.
EROSION CONTROL PLAN FOR
SPEC DAYCARE - LELAND
Area to be disturbed: +3.5 acres
The project includes the construction of a 12,100 SF Daycare Facility. The storm water
system will consist of sheet flow across the parking lot discharging to a grassed swale.
EROSION CONTROL MEASURES: This project will primarily control erosion with the
use of a temporary construction entrance, a temporary Sediment Trap and silt fence on the
downslope of areas that will be disturbed.
The contractor shall install, maintain and remove upon completion the silt fence as
necessary to prevent any sediment from leaving the project limits. This will include any
temporary stockpile areas if' necessary. Contractor shall clean and restore to pre -
construction conditions any areas that may inadvertently be damaged due to the failure of
the erosion control measures.
SCHEDULING OF WORK: Clearing and grubbing shall be scheduled and performed in
such a manner that fine grading operations and erosion control practices can follow
immediately thereafter. Excavation 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 the specifications within 21 working days after completion of
active construction.
MINIMUM AREAS TO BE DISTURBED: Only those areas necessary for timely and
proper completion of the project shall be stripped of native vegetation. The angle for
graded sloped 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 be stabilized, within 21 calendar days of completion of any phase of
grading, be planted or otherwise provided with ground cover, devices, or structures
sufficient to restrain erosion.
PLACEMENT OF SEDIMENT CONTROL DEVICES: All devices (sediment fences,
construction entrances, etc.) for sediment control shall be constructed prior to beginning
clearing and grubbing on the site.
FINAL COVER: As soon as practicable after finished grades have been established, all
operations in connection with establishing final ground cover shall be performed. Any
inactive disturbed ground area to remain denuded more than 21 days shall be temporarily
seeded in accordance with the temporary seeding schedule as noted on the plans.
