conditions and limitations:
I. DESIGN STANDARDS
1. The project is permitted for 280 lots, each limited to a maximum of 6,000 square feet of built-upon area, as
defined by the stormwater rules,and as indicated in the approved plans. CAMA regulations may reduce the
built-upon area for those lots within the AEC.

must be maintained at a minimum of 100' long with 5:1 (H:V) side slopes or flatter, have a longitudinal
slope no steeper than 5%, carry the flow from a 10 year storm in a non-erosive manner, and maintain a
dense vegetated cover.

Ill. CURB OUTLET SYSTEM MAINTENANCE REQUIREMENTS
1. Mowing will be accomplished as needed according to the season. Grass height will not exceed six inches
at any time.
2. Swales will be inspected monthly or after every runoff producing rainfall event for sediment build-up,
erosion, and trash accumulation-
3. Accumulated sediment and trash will be removed as necessary. Swales will be reseeded or sodded
following sediment removal.
4. Eroded areas of the swales will be repaired and reseeded. Swales will be revegetated as needed and in a
timely manner based on the monthly inspections.
5. Catch basins,curb cuts, velocity reduction devices, and piping will be inspected monthly or after every
significant runoff producing rainfall event. Trash and debris will be cleared away from grates,curb cuts,
velocity reduction devices, and piping.
6. Swales will not be altered, piped,or filled itt without approval from NCDENR Division of Water Quality.
I acknowledge and agree by my signature below that I am responsible for the performance of the six
maintenance procedures listed above. I agree to notify DWQ of any problems with the system or prior to
changes to the system or responsible party.

NOTES:
Noelle,
Included is a sample calculation of velocity and flow depth as per your request. These
values were computed using FlowMaster software, which manipulates Manning's
equation to salve for the depth and velocity. The enclosed calculation reflects the
method used for all values submitted on form 5WU-105 where the differing variables
for each swale are the flow and the channel slope. The Mannings Coefficient and
sideslopes are the some for each swale. If you have any questions please feel free to
contact myself or Davis Fennell.
Thanks
Andrew M. Osborn

DESIGN iNARRATIVE
1. GENERAL:
The project site is located off of(SRI 119)Stone Chimney road approximately 3/4 of a mile south
of the Stone Chimney road and Sabbath Home road intersection within Brunswick County,North
Carolina. This phase of the project site is approximately 231.14 acres. Drainage considerations
are to be in accordance with DWQ stomtwater requirements.
The intent of this project is to develop streets, drainage improvements and a development office
with parking. This development will support 281 single-family homesites in this first phase of
construction. The impervious coverage has been kept to a minimum to promote infiltration as
much as possible. These home sites will average 1/2 of an acre in area and limited to no more
than 6.000 sq. ft.of built upon area per lot.
2. EXISTING SITE:
Site topography in the area is relatively flat with slopes typically less than(2)percent. There are
low areas throughout the site that drain to wetlands, which will provide positive drainage for the
area to the Spring Creek and to the Atlantic Intracoastal Waterway. Vegetation consists primarily
of grasses and minor ground cover within the area of the improvements. Subsurface soils are
typically a mixture of sands,silty sands and organics.
3. PROPOSED IMPROVEMENTS:
improvements proposed include drainage devices,streets,utilities and a development office with
parking. Drainage for the most part will sheet flow from the lots into the streets which will have
curb and gutter to direct drainage to low points or curb outlets in the roads. Drainage at the low
points in the streets will flow into trench drains and curb inlets which then outlet into vegetative
swales that will be constructed with SA side-slopes and a minimum length of 100 feet. In some
instances in this project, once the storm water flows through the vegetative swales at the
minimum design criteria, it will drop into an inlet box and be directed via subsurface pipe to an
outlet source. This outlet source will be either a drainage ditch or the proposed marina basin. In
the case of a pipe directed into the marina basin, the pipe will be set to an elevation so that the
pipe will be below the marina basin water surface. The storm water that enters the proposed
subsurface pipe will be treated prior to entering this conveyance pipe.The pipe lengths have been
kept to a minimum and are needed only to convey treated storm water due to the topography
limitations. Piping will be perforated and installed at relatively flat slopes to promote infiltration
when possible.The soils are very sandy and ideal for infiltration.
