South Wilmington Wetland Park

South Wilmington Wetlands Project

Project Details:

The purpose of the 14-acre wetland park in South Wilmington is to create a stormwater management facility, restore and enhance existing wetlands, and create a new park for the community.

The South Wilmington Wetlands Park will also increase local walkability and recreational opportunities. The most prominent design feature of the site is a wide, ADA accessible boardwalk/on grade pathway through the heart of the park. This pathway will function as a recreational opportunity for local residents as well as visitors that will also allow the Southbridge community to access nearby jobs and retail shopping. The South Wilmington Wetlands Park will provide flood relief to Wilmington's historic Southbridge neighborhood and clean up one of the largest brownfields in the City. According to the Environmental Protection Agency, a brownfield is a property that may have hazardous substances, pollutants or contaminants present. Building the Wetlands Park will require the removal of contaminated soil which was dumped into the marsh over the past hundred years. Diamond Materials is working with the City of Wilmington to ensure that the park will be safe for people to enjoy and a place where fish, birds, and wildlife can safely live.

The Wilmington Wetlands project is moving right along! Diamond Materials Foreman, Kenny Biddle is excavating and installing a slide rail shoring box to safely install the Automated Tide Valve Structure. The Automated Tide Valve Structure will allow the City of Wilmington to remotely control the water level in the wetland park. During heavy rain, the valve can be closed, allowing the rain water to be held in the wetland park and release it slowly when the storm is over. This entire system was designed and inspected by RK&K Engineering with Bruce Jones and Joni O’Brien, CCM leading the effort.

Diamond Materials Foreman, Eric Morlino is also installing a coffer cell at the river. This coffer cell is necessary to keep water from the river out of the excavation during construction of the Automated Tide Valve Structure.
