Wilmington Sports Complex, 401 Garasches Lane, Wilmington, DE
The Wilmington Sports Complex is the 76ers Fieldhouse and the home of the 76ers’ G League affiliate, The Delaware Blue Coats. The facility is a 161,000 square-foot, 2,500 seat multipurpose sports complex and youth training center on the east side of the Christina River in Wilmington, Delaware and was built on a Brownfield site. This area of Wilmington is an under-served area and the facility brings sporting opportunities to the community provided by BPG ǀ Sports, Sports Medicine provided by Nemours Sports Medicine and Rehabilitation Facility and elite services provided by Titus Sports Academy. The facility has three professional size basketball courts and an international size indoor and outdoor soccer field. The facility hosts sporting events including elite level tournaments,events to raise funds for local nonprofits, open court time for all age groups which often include some of the Delaware Blue Coats players participating, and concerts.
The property was a vacant brownfield site and as a result of the prior use both soil and groundwater contamination were present on the property and the adjacent ditch which drains to the Christina River. The remediation of the environmental issues on the site is designed to improve the quality of stormwater and groundwater flowing from the site into the Christina River and the South Wilmington Wetland project which is currently being remediated to establish a wetland park and a stormwater storage area. Development of the Sports Complex also resulted in land previously prone to flooding being raised out of the flood plain making the site resilient to future flooding issues.
The remedial technologies used to address the contamination on the site included an impervious cap, grouted GeoPiers, reactive core mats and removal of contaminated ditch sediments. The GeoPiers are a ground improvement technology which is typically constructed using just stone. Due to the groundwater contamination in the shallow aquifer on site, the GeoPiers construction included grout to prevent the downward migration of contaminants. The reactive core mats were installed under the culvert system in the ditch to allow for treatment of the groundwater traveling offsite. The culvert installation provided a barrier to contaminated sediments, allowed for the removal of some of the contaminated sediments, and transportation of stormwater to the wetlands and Christina River while preventing contaminated sediments from being carried along in the stormwater.
As a part of the redevelopment of the site, a new road project created access to the building and will eventually link the site to the west site of the Christina river providing a multimodal system to connect the underserved community with the amenities of the redeveloped Wilmington Riverfront, including an urban wildlife refuge. After the Sports Complex was constructed, a new 300 unit apartment complex was announced in the same area, suggesting as planned, the Sports Complex will be the catalyst for the redevelopment of the east side of the Wilmington Riverfront.
