Stormwater Management Pond - Final Design Narrative
May 30, 2001 >i JUN 2 6 2001 I
1. Introduction
A stormwater Management is designed for the Bertie Memorial Hospital Site and for future
expansion for water quality control. The stormwater management (SWM) pond is designed to
meet the State North Carolina Department of Environmental and Natural Resources criteria. The
site is located in Windsor, North Carolina within Bertie County. The project is classified as a
high -density development since the site includes a storm water collection system consisting of
curb and gutter and storm sewer pipes. The drainage area of the pond consists of 10.04 acres
including 3.14 acres of impervious areas that will be build in the first phase. Impervious areas
include the hospital building roof, parking lots, sidewalks, concrete pad areas and a helicopter -
landing pad. Future expansion of the site with additional impervious area may occur. The SWM
pond will be designed to accommodate the first phase as well as future expansion.
2. SWM Pond design parameters and configuration
The design for water quality control is based on guidelines established in Storrnwater Best
Management Practices, North Carolina Department of Environmental and Natural Resources,
Division of Water, April 1999. For water quality control the SWM pond will include a
permanent pool, an aquatic bench and a sediment forebay. No vegetated filter is provided;
therefore the 90% TSS removal design criteria were used for sizing the permanent pool. Based
on a geotechnical investigation performed on March 27, 2000, by CPEC Environmental Inc., the
estimated seasonal high-water table in the proposed pond location is estimated at 8194 feet. The
permanent pool elevation was set at elevation 81.0 feet, 09 feet below the seasonal high water
table in order to maintain a permanent pool. Temporary storage is provided based on a one ( 1)
inch runoff event. The percentage impervious equals 31.5%, which was rounded up to 35% for
design purposes. Based on the Required SAIDA table provided by the Washington District
Office of Division of Water Quality, for an imperviousness of 35 % and a design depth of 3 feet,
a SAIDA of 4% is required. The actual pond SAIDA ratio is 6.2%, which allows for potential
future expansion of the site. The total maximum depth used for design equals 4 feet, which
includes one foot of sediment storage. The side slopes of the wet pool was set at 3:1, the
sideslopes above the wet pool was set at 4: I. A 10-feet wide aquatic bench was included which
will be seeded with wetland plants. The aquatic bench will also serve as a safety feature. Table
1 below presents the key hydrological and pond characteristics.

3. Final drainage configuration and results of analysis
The stormwater management pond services two subareas. The first sub -area consists of the
hospital building, the main parking lot, the helicopter pad, other miscellaneous impervious areas,
grassed and landscaped areas, and an undeveloped portion. A storm sewer system collects the
runoff from the roof drains, parking lot and other impervious areas and drains it into the pond' at
Structure Number H-l. The inflow pipe consists of a 30-inch pipe and drains into a forebay
Number. A baffle consisting of an earthen berm within the pond was included to increase the
flow length of the discharge from the storm sewer through the main wet pool to at least 3A
average length to average width ratio.
The second subarea consists of a parking lot located immediately to the east of the hospital
building and the grassed area south of the hospital building and main parking lot. Runoff from
the second sub -area drains into a vegetated Swale and into the eastern forebay number 2 of the
stormwater management pond.
The outfall structure consists of a 36-inch corrugated metal riser pipe with a trash rack. A
drawdown time of 2 days was used to size the water quality opening. A 2.3/8-inch diameter
opening is required with an actual drawdown time of 2.2 days. The invert elevation of the 2 3/8-
inch opening is set at elevation 81.00, and controls the permanent pool elevation. The trash rack
protects the water quality opening. The crest of the riser pipe is required to be at elevation 81.45
feet to store the volume of 13,302 cubic feet produced by a one -inch runoff event. The crest of
the riser pipe is set at elevation 81.50 feet. The pond has an emergency spillway at elevation
83.0 discharging into an existing ditch.
Storm routing of the 10-year and 100-year design storm was used using the modified rational
equation to develop an inflow hydrograph and routing it through the pond using calculated stage -
storage and stage -discharge relationship. Software developed by Intellisolve Inc., Hydraflow-
Hydrographs was used for storage routing. Based on the routing calculations for a critical storm
duration of 30-minutes, the peak pond elevations for the '10-year and the 100-year events equaled
82.50 ft and 82.97 feet respectively. The peak outflow equaled 10.7 cfs and 14.9 cfs for the 10-
year and the 100-year events respectively.

Future expansion of the hospital site potentially includes additions to the existing hospital
facility, parking lots, as well as additional buildings. Based on the design SA/DA ratio of 6.2 %
and with a design depth of 3 feet, a maximum of 58.5% percentage of imperviousness is allowed
for the site without enlarging the SWM Pond. With a proposed imperviousness of 31.5 % for
Phase I, an additional 118,000 square foot is available for future expansion.

Subject: Stormwater Permit Renewal
Stormwater Management Permit SW7000108
Bertie Memorial Hospital
Windsor, NC, Bertie County
A Division -of Energy, Mineral, and Land Resources file review has determined that
Stormwater Permit SW7000108 for the construction and operation of a wet detention pond
to serve the Bertie Memorial Hospital will expire on August 10, 2015 and the Division has
not received an application for renewal. This is a reminder that the stormwater rules (15 A
NCAC 2H .1000) require that applications for permit renewals be submitted 180 days prior
to the expiration of a permit. Operation of a stormwater treatment facility without a valid
permit is a violation of NC General Statute 143-215.1 and may result in an appropriate
enforcement action including assessment of civil penalties.
Please submit a completed renewal application along with a processing fee of $505.00
before the required date. The permit renewal application forms can be found on our
website at http://portal.ncdenr.org/web/Ir/state-stormwater-forms docs . If you have
questions, please feel free to contact me at [phone].
