The long-empty Chesterfield Mall site is about to get a lot less ghost town and a lot more hard hats. Starting in May, the city plans to map sewer, gas and water lines across the property as it leans into turning the vacant expanse into a walkable, mixed-use "Downtown Chesterfield." City leaders say the shift from demolition to infrastructure work is the key step that will unlock new streets, utilities and a central park. Neighbors can expect to see more survey crews and planners roaming the site as the city and developers sync up on the next phase.
In a statement to First Alert 4, Chesterfield officials said the push in May will center on infrastructure planning, beginning with detailed utility mapping and subsurface surveys to locate existing sewer, gas and water lines. They described that mapping as a necessary first move that will guide where roads and public utilities are routed before any above-ground construction can start.
Developer Says Early Sitework Is Already Underway
The project’s developer, The Staenberg Group, says the heavy lifting behind the scenes has been going on for a while. In a Dec. 1, 2025 press release, Downtown Chesterfield announced that utility installation and grading had already begun and that early work would zero in on the future road network and a roughly 3.3-acre central park at the heart of the development.
Project Scale And Timeline
Developer materials and industry coverage describe Downtown Chesterfield as a multi-phase, roughly $2 billion overhaul that will mix ground-floor retail with renovated anchor spaces and thousands of homes. Reporting from ShoppingCenterBusiness puts the plan at millions of square feet and about 2,300 residential units, with site grading and utility work expected to continue through 2026 before vertical construction moves in.
Money And Legal Questions
The makeover is backed by a sizable tax-increment financing package meant to cover roads and utilities, according to the St. Louis Business Journal. That public support has drawn scrutiny, with critics questioning both the cost and the approval process. The redevelopment plan also prompted a 2023 lawsuit from Dillard’s that accused the city of improperly steering incentives, a clash that First Alert 4 covered along with the city’s denials of collusion.
What Residents Will See Next
City officials say the utility mapping will kick off in May and that this early infrastructure phase, focused on utilities, grading and street layouts, will largely determine when developers start asking for building permits. Observers expect that groundwork to take most of a year, and industry reporting along with developer timelines suggest the site could be ready for vertical construction in 2027, with the first residences opening after that. For residents trying to keep tabs on the project, developer updates and city planning agendas will remain the best places to watch for specific dates, public meetings and the next big milestones.
