PSL Sells 22.8 Acres to Costco for $6M, but Is the Price Right?

Port St. Lucie's city council voted unanimously this week to sell 22.8 acres of publicly owned land in the Southern Grove development corridor to Costco Wholesale for $6 million — a deal that Mayor Shannon Martin called "a win for our residents and our local economy."

At roughly $263,000 per acre, the sale price deserves scrutiny. Comparable commercial land transactions along the Interstate 95 corridor in St. Lucie County have fetched significantly higher per-acre values in recent years According to initial reports,, raising questions about whether the city left money on the table to land a marquee retailer — or whether Southern Grove's still-developing western infrastructure justifies the discount.

City officials did not immediately release the full terms of the purchase and sale agreement, including any infrastructure obligations, site preparation commitments, or reverter clauses that would require Costco to break ground within a specified window According to initial reports,. Those details matter. Land deals structured as economic development incentives frequently embed conditions that protect taxpayers if a retailer delays or cancels construction — or they don't, and the public finds out later.

Costco is proposing a 170,000-square-foot retail warehouse and gas station on the parcel, located east of SW Village Parkway and south of the newly constructed SW Marshall Parkway. The site sits adjacent to a Costco distribution center that is expected to employ more than 500 people and is slated to open this month, though construction remains ongoing.

That adjacency is not incidental. Costco rarely places retail stores next to its own distribution infrastructure by accident. The company announced plans to open 28 new stores nationally this year, and the Port St. Lucie location appears to fit a deliberate hub-and-spoke strategy — pairing a fulfillment center with a consumer-facing warehouse club to maximize regional logistics efficiency According to initial reports,.

Southern Grove is a sprawling master-planned district west of I-95 that the city has been cultivating for years as its primary commercial and industrial growth engine. Locking in Costco as an anchor tenant sends a signal to other prospective developers — but it also locks in a price point and a land use that will shape the district's character for decades.

Martin, who championed the deal publicly, did not detail what competing offers, if any, were considered before the council approved the Costco agreement.

The Sentinel has requested the full purchase and sale agreement, including any infrastructure cost-sharing provisions and performance timelines, under Florida's public records law. The city had not responded as of publication.

What is clear: Port St. Lucie traded a significant public asset for a retailer its residents have wanted for years. Whether the terms reflect full market value — or a subsidy dressed up as a sale — is a question the council did not appear to ask publicly before voting.
