PROJECT NARRATIVE
CITY OF WILSON
MERRIMONT PARK STORMWATER PROJECT
WILSON COUNTY, NORTH CAROLINA
PN: 09 -144
Proiect Description
The City of Wilson has designed a stormwater improvements project at the existing Memmont
Park along Buckingham Road in the northwestern region of the City The purpose of the project
is to begin the City's initiative to remove Hominy Creek from the 303 (d) list of impaired
streams When this area was originally developed, there were no nutrient loading limits, no
stormwater or land use ordinances in effect The scope of this project shall include rerouting
of existing storm drainage through a new Wet Pond BMP, including approximately 1,350 linear
feet of 15 -inch through 24 -mch RCP Storm Drainage The project has been designed to
effectively reduce the amount of pollutants and sediment that have otherwise laden the
downstream basin for years The project will also include side stream storage, greenway trails,
and educational resources to allow local college students, local residents and children the
opportunity for research and education on stormwater BMP and the local environment The
project vicinity is nearly 100% developed There are two (2) existing ditches onsite, which will
be rerouted to correspond to the new stormwater design The total project area is approximately
6 0 acres
Site Description
The topography in the project area is essentially flat but with a few mild slopes ranging up to 20%
along the exterior boundaries All construction will take place either on City of Wilson property
or existing public Rights -of -Way of Buckingham Road and Westminster Drive
Planned Erosion and Sedimentation Control Measures
1 Silt Fencing — Silt Fence will be installed as shown on the construction plans or as
deemed necessary by visual inspection This will be done by the contractor and
inspected by the engineer to ensure all sediment is properly contained
2 Rock Check Dams — Rock Check Dams will be installed as a temporary measure
throughout the project to restrict the velocity within the disturbed roadside ditches or
channels affected thereby reducing the potential of erosion These check dams will
also serve as temporary sediment traps and will be placed wherever necessary as
shown on the construction plans
3 Diversion Ditch — Will be provided to route storm water to the necessary measures
4 Sediment Basin with Riser — will be provided to settle out sediments that do get
trapped before discharge to the stream
