STORM WATER NARRATIVE
WEDGEWOOD AT LANVALE
SITE DESCRIPTION
The t 99 acre site is located within the Town of Leland Limits on the east side of Lanvale
Road (S.R. 1438) and'in Brunswick County on the west side of Lanvale Road . This project
includes existing, proposed, and future development draining to Pond No. 1 of the
subdivision. The approved stormwater permit no. SW8 031055 includes the existing
development of phases I and 1 B (lots 1-81) and the design of Pond No. 1. The proposed
phase 1C (lots 82-108) includes clearing, grading, and installation of roadways and
infrastructure for 27 single-family lots. The future development is shown on the plans as
the cross hatched areas that will be finalized later.
LOW DENSITY REQUIREMENTS
The low density requirements for this project require the impervious area to be 30% or less
of the total boundary area. Shown below are the low density calculations:
Phases 1 A, 1 B, and 1 C Total boundary area = 1,674,987 sf
Total impervious area = 499,895 sf
% Impervious = (499,895/1,674,987) = 0.30 — 30%
Future development Total boundary area = 1,871,753 sf
(Phase 2) Total impervious area = 561,525 sf
% Impervious = (561,52511,871,753) = 0.30 — 30 %
Future development Total boundary area = 772,398 sf
(West of Lanvale Road) Total impervious area = 231,719 sf
% Impervious = (231,719/772,398) = 0.30 -- 30 %.
STORMWATER IMPROVEMENTS:
The primary stormwater measures include curb and gutter and catch basins within the -
right -of -way. All storm culvert systems that are existing or proposed outfall either directly
into Pond No. 1 or the Amenity Ponds 2 and 3. The storm drainage from the amenity
ponds is routed to Pond No. 1 where the one -inch runoff is treated.
Pond No. 1 was designed as a wet pond with a permanent pool elevation of 24.0 and a
temporary pool elevation of 25.5. Due to the increase of impervious area from the
proposed Phase 1 C and the allocated impervious areas from future phases, the temporary
pool elevation has been modified to 25.9. Therefore the existing outlet structure for Pond.
No. 1 must be raised 0.4 feet and the orifice diameter has increased to 4 inches. The
calculations for the revisions to Pond No. 1 are attached.

' When using the Division SAIDA tables, the correct SAIDA ratio for permanent pool sizing should be computed based upon the
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%'rSS removal and 90% TSS removal.
11. REQUIRED ITEMS CHECKLIST

This system (check ogre) X does _ does not incorporate a vegetated filter at the outlet.
'this system (check one) _ does X does not incorporate pretreatment other than a forebay.
Maintenance activities shall be performed as follows:
l . After every significant runoff producing rainfall event and at least monthly:
a. Inspect the wet detention basin 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 be handled in a manner that will not 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 as such that it will give an accurate
depth reading and not readily penetrate into accumulated sediments.
When the permanent pool depth reads 18.38 feet in the main pond, the sediment shall be removed.
When the permanent pool depth reads 20.25 feet in the forebay, the sediment shall be removed.

Footnotes:
When using the Division SAIDA tables, the correct SAIDA ratio for permanent pool sizing should be computed based upon the
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% TSS removal.
I1. REQUIRED ITEMS CHECKLIST
The following checklist outlines design requirements per the Stormwater Best Management Practices Manual
(N.C. Department of Environment, Health and Natural Resources, February 1999) and Administrative Code
Section: 15 A NCAC 2H .1008.
Initial in the space provided to indicate the following design requirements have been met and supporting
documentation is attached. If the applicant has designated an agent in the Stormwater Management Permit
Application Form, the agent may initial below. If a requirement has not been met, attach justification.
Applicants Iijitial
a. The permanent pool depth is between 3 and 6 feet (required minimum of 3 feet).
b. The forebay volume is approximately equal to 20% of the basin volume.
c. The temporary pool controls runoff from the design storm event.
--`� d. The temporary pool draws down in 2 to 5 days.
e. If required, a 30-foot vegetative filter is provided at the outlet ( include non -erosive flow
calculations)
ate— £ 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.
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.
I. If the basin is used for sediment and erosion control during construction, clean out of the
basin is specified 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:
After every significant runoff producing rainfall event and at least monthly:
a. Inspect the wet detention basin 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.
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 be handled in a manner that will not 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 as such that it will give an accurate
depth reading and not readily penetrate into accumulated sediments.
When the permanent pool depth reads 5.62 feet in the main pond, the sediment shall be removed.
When the permanent pool depth reads 3.75 feet in the forebay, the sediment shall be removed.
