Port St. Lucie has taken a significant step toward adding a new retail option, as city leaders approved a land deal for a future Costco store proposal in the Southern Grove area. The main keyword, Costco store, is central to the city’s latest development plans.
Costco Store Project Moves Forward in Port St. Lucie
According to official city documents, the Port St. Lucie Governmental Finance Corporation voted unanimously on March 9, 2026, to authorize a purchase and sale agreement with Costco Wholesale Corporation. The agreement covers approximately 22.8 acres of land near the southeast corner of Southwest Village Parkway and Marshall Parkway in Southern Grove.
The sale price for the property is $6 million. The deal enables Costco to construct a retail warehouse store of up to 170,000 square feet. Plans for the site may include a gas station, pharmacy, tire center, and other services, according to city documents.
Details of the Land Agreement for the Costco Store
The land deal involves several specific terms. The Governmental Finance Corporation, which consists of all five City of Port St. Lucie City Council members, is overseeing the transaction. The agreement requires a $300,000 deposit from Costco and allows for a 90-day inspection period. Costco will have 270 days to secure development approvals before the transaction closes.
City obligations under the agreement include extending Marshall Parkway, providing access to water, sewer, and utilities, and supplying fill material for the site. The city will retain two smaller outparcels and has placed restrictions on competing retail uses—such as other wholesale warehouse clubs or large grocery stores—within a one-mile radius of the property.
Location and Surrounding Development
The future Costco store is planned for a site adjacent to a major distribution depot, which is currently under construction in Port St. Lucie. According to city documents, the depot is expected to generate more than 500 jobs in the Southern Grove jobs corridor for the area.
The nearest existing Costco location for Port St. Lucie residents is about 20 miles away in Stuart. That store, located on South Kanner Highway, opened in 2025 and was the first Costco on the Treasure Coast.
Next Steps for the Costco Store Project
If the project proceeds as planned, construction of the Costco store could begin after all necessary development approvals are obtained. City documents indicate that the process will advance Port St. Lucie’s retail growth, especially in the Southern Grove area, joining other new development projects coming soon to PSL.
Details may be updated as the project moves through the approval and development stages, according to official sources.
