Costco Warehouse Moves Closer to Opening in Port St. Lucie

I'll search for recent healthcare, hospital, retail, or infrastructure openings on Florida's Treasure Coast.Let me search for more recent healthcare or infrastructure news from August 2026 specifically.Based on my research, I have found several recent projects, but the most substantial and recent news involves the Costco retail warehouse store that received zoning approval in mid-July 2026. This is a current and concrete development. Let me write the brief:

---

Costco moved closer to opening a warehouse in Port St. Lucie after the City Council approved a zoning amendment allowing member-based wholesale warehouse stores at the proposed site in Southern Grove. The amendment adds warehouse stores of at least 100,000 square feet as a permitted use and allows features including outdoor seasonal merchandise displays, a tire center, liquor sales and a fuel station.

The proposed store would total about 158,000 square feet on roughly 22.8 acres near the intersection of Southwest Village Parkway and Marshall Parkway, across from Costco's distribution depot, which is under construction. Officials anticipate a 2027 opening.

City leaders approved the sale of approximately 22.8 acres to Costco on March 9, 2026, setting the stage for this July zoning action. The timing aligns with the region's rapid growth in retail and logistics infrastructure.

**What it means for you:** If you're relocating to the Treasure Coast as a retiree, a Costco warehouse means expanded shopping options and competitive bulk pricing for household goods—valuable for those stretching fixed retirement income. The store's proximity to Southern Grove also signals continued commercial growth and convenience in Port St. Lucie's developing areas, enhancing daily-living amenities for 55+ residents choosing where to settle.
