St. John Jewel-Osco Opening and Heartland Park Update

Drive down Wicker Avenue past 93rd Avenue and you have seen the same thing for over a decade: a fenced-off, sun-bleached hulk of a building that used to be a Kmart, sitting on some of the most trafficked frontage in Lake County doing absolutely nothing. That changes on September 16, 2026, when Jewel-Osco holds its grand opening at 9548 Wicker Ave, inside the same 70,000-square-foot shell that has sat empty since the Kmart closed in 2012.

It is easy to read that as a single retail story. It is not. A few miles north, Heartland Park is in the middle of a 40-acre expansion that broke ground in April and is still mid-construction. Put the two projects next to each other and a pattern shows up that explains a lot about what living in St. John has actually felt like for the last several years: the houses came first, and everything else is still catching up.

A Grocery Store Finally Replaces the Ghost on Wicker Avenue

The numbers on this project are bigger than a typical grocery store opening. Indianapolis-based DeMao Retail has described the redevelopment as a $31 million project, and the plan called for a near-total gut of the old Kmart, keeping only structural elements like the steel frame while replacing everything else. The result, according to reporting at the time, is meant to be a newer, higher-end Jewel-Osco format than the chain's other Northwest Indiana stores in Munster, Dyer, Crown Point, and Chesterton, with a Starbucks and a drive-thru pharmacy built in from the start.

Here is what residents will actually walk into on the 16th:

That vacancy mattered to more than aesthetics. St. John residents already have Strack & Van Til, Target, and Aldi on the same corridor, so this isn't a town solving a food desert. It is a town finally converting its most visible eyesore into something that functions, after years of the site sitting as a symbol of how far retail had fallen behind the rooftops going up around it.

Forty Acres North of Town Are Still Turning Into Something

Heartland Park is the other half of this story, and it is the slower half. The expansion project will reshape 40 acres at White Oak Avenue and 109th Avenue, adding an amphitheater with a covered stage and seating, an open-air pavilion, year-round community rooms, and what the town has specifically called a destination-style splash pad, with slides, climbing structures, and vertical water features.

Groundbreaking happened in April 2026. As of the town's own July project update, the building pad had been brought up to grade and roadway work was underway, meaning most of what residents will see through this fall is dirt work and equipment rather than a finished amenity. The town structured the financing through a bond issue designed to be largely tax neutral if assessed value growth holds to projections, and public comment at council meetings has run mostly in favor.

None of this opens in September. That is the point. The grocery store gives residents a finish line they can see and use this month. The park gives them a finish line still a year or more out, visible only as graded dirt and construction fencing right now. Both are proof that the town is actively closing gaps that have existed for years, just on very different timelines.

Retail Chasing Rooftops, a Decade Late

As of last year's reporting, St. John's population had grown from around 8,000 three decades earlier to more than 24,000, and that growth was not gradual. A large share of it came from Illinois transplants drawn by lower property taxes and the newer South Shore Line double-track service, and the town's population had climbed by roughly 25 percent in just the five years leading up to that count.

Subdivisions went in fast. Commercial development did not keep pace, and residents noticed. For years the complaint around town was some version of not wanting to drive ten or twenty miles just to get somewhere ordinary, whether that meant groceries, a haircut, or a cup of coffee. The Arcadia Center at Wicker and 101st Place eventually added eight storefronts to bring in tenants like AT&T, Sport Clips, and Tropical Smoothie Cafe. St. John Commons on Calumet Avenue brought in The Daily Grind Coffee and Ice Cream Shop and The Great American Bagel. Each of those filled a gap, but the Kmart site sat there through all of it, the largest unresolved piece of the puzzle.

This fall's Jewel-Osco opening is not a new trend. It is the last domino in a retail catch-up that has been running for years, just the biggest and most visible one.

The Calendar Fills In Before the Construction Fences Come Down

While the big infrastructure projects finish on their own schedules, the town's fall calendar is already locked in and worth marking down now.

• St. John Oktoberfest, October 2 through 4, at the St. John the Evangelist Parish lot on Wicker Avenue. The lineup includes the Ed Wagner Band, Pech Schwefel, the Gronik Children's Folk Ensemble, German Band Inc., and Prost!, with a beer garden pouring Hacker-Pschorr and two TVs set up for college and NFL football.
• Boo Bash, October 17, at Prairie West. Expect pumpkin train rides, trunk-or-treat, pumpkin decorating, and a costume parade, timed for late morning.

Neither of these events depends on the Jewel-Osco or the park expansion finishing. They are the parts of St. John that already work, running on the same schedule they always have while the bigger, slower projects work themselves out in the background.

What This Actually Means for the Neighborhood

The story here is not that St. John got a grocery store. It is that a town which grew its housing stock faster than almost anywhere else in the state is now visibly working through the backlog that growth created. The Kmart site is the easy, fast-moving half of that backlog. Heartland Park is the slow, expensive, still-unfinished half. Both are proof the gap is closing, not evidence that it already has.

If you already live here, that is useful context the next time you drive past either site. If you are watching St. John from the outside and wondering whether the town's growing pains are settling down, September 16 and the ongoing work at Heartland Park are the two dates worth tracking.
