5625 Barbados Boulevard
The 7.10 acre site is located near the intersection of SR 1002 (Holly Shelter Road) and SR 2662
(Barbados Boulevard) in an unincorporated portion of New Hanover County, NC. The site and
adjoining properties are zoned B‐2 and are in the Island Park planned commercial subdivision.
Proposed improvements are consistent with this zoning and includes 24,000 sf of general office
space to be utilized as a recreational vehicle sales facility. The proposed building and drainage
facilities are situated to allow for the future subdivision of the property.
The site is presently vacant and is vegetated with a stand of 10” ‐ 20” pine trees. Few
significant trees are located onsite. The site is primarily drained to an outfall ditch in the
southwest corner of the site that drains to the south and ultimately to the I‐40 roadside ditch.
Access to the site is proposed by two full‐movement driveways off of Barbados Boulevard.
Internal drive aisle widths are sufficient to allow fire apparatus access.
Water and sewer service will be provided by taps on CFPUA mains in Barbados Boulevard. The
daily water usage is calculated to be 300 GPD based on NCDEQ rules which prescribe 25 GPD
per employee of general office use.
Stormwater runoff will be collected by inlets and conveyed via RCP to an NCDEQ wet pond
located adjacent to Barbados Boulevard. This pond is designed to treat and release the 1.5”
storm in 2–5 days. This NCDEQ treatment volume stages the pond up to an elevation of 25.2.
This volume is released towards Barbados Boulevard via a 2.5” orifice at a rate that does not
exceed the 1 year, 24 hour predevelopment runoff rate. Upon staging above the 25.2 NCDEQ
temporary pool elevation, runoff is directed to 3 detention basins located at the northeast,
northwest, and southwest corners of the site. The primary outfall structure is located in the
detention basin in the southwest corner of the site and is designed to release the 2, 10, and 25
year storms at a rate that does not exceed the predevelopment rate. Additionally, the primary
outfall structure is designed to accommodate the 100 year storm without discharging over the
emergency weirs. The NCDEQ wet pond and primary detention basins are linked via 30 inch
RCP. Both basins are provided emergency overflow weirs to allow for a controlled discharge
should this pipe become obstructed.
Erosion control is accomplished through the temporary use of gravel construction entrances,
silt fence, and hardware cloth and gravel inlet protection. The stormwater pond will be used as
a skimmer basin during site construction and will be converted to a stormwater basin once the
site is stabilized. Riprap aprons will be installed and left in place at all pipe outlets.
