Mayor Welch extends proposal deadline for 86-acre Historic Gas Plant redevelopment in downtown St. Pete
/Starting in the new year, the City of St. Pete will officially restart the clock for developers to submit proposals to redevelop the 86-acre Historic Gas Plant District in downtown St. Pete, marking the third time the city has sought bids for the site since 2020.
Mayor Ken Welch had initially planned to open a 30-day submission window in mid-November, but after receiving pushback from major developers, including Kolter Urban and Red Apple Group, as well as concerns from City Council, Welch agreed to delay the start until January 4th, 2026.
Proposals will now be due February 3rd, giving developers a total of 105 days since the city’s October 21st announcement.
The latest bid solicitation was triggered when the city received an unsolicited $6.8 billion proposal from Casey Ellison of Ellison Companies, Cathie Wood of ARK Invest, and Jonathan Graham of Horus Construction.

Pre-leasing is set to begin Saturday, August 15th, with move-ins scheduled after the new year at the first apartment community in Sky Town, an $800 million mixed-use development underway in St. Petersburg’s Skyway Marina District.
The 401-unit iMMiX Apartments, located at 3201 34th Street South, are part of the first phase of the 34.3-acre development being built on the former Ceridian office campus.
Once complete, Sky Town will include 2,084 apartments, 69,000 square feet of retail anchored by a 23,000-square-foot Sprouts Farmers Market, and 120,000 square feet of self-storage across six phases.
Coral Gables-based Altis Cardinal, led by developer Frank Guerra, broke ground on the iMMiX Apartments in September 2025, with Jacksonville-based Summit Contracting Group serving as general contractor.
