Your Jenison Summer Just Got Rearranged. Here's the Map That Still Works.

If you have lived in Jenison for even a couple of summers, you know the pattern. A Monday evening walk to the library market, a Saturday loop on Kent Trails from the Clean Water Plant lot, a slow drive up 42nd Avenue when Baldwin gets busy. Most of that pattern is under a cone this year.

The interesting part is what's happening while the orange barrels are up. The Idema Explorers Trail has quietly stitched together a river route that did not exist three summers ago, the Georgetown Township Farmers Market has locked into a rhythm worth planning your week around, and the closures on the road side are opening a short window to actually learn the trail network before it becomes the obvious answer for everyone. This post is a working map of that shift.

The Monday That Anchors the Week

Everything else moves around the market. Every Monday from June 15 through August 24, 2026, the parking lot behind the Georgetown Township Public Library at 1525 Baldwin turns into the closest thing Jenison has to a downtown square, running 4 to 7:30 p.m. It is a fifteen-minute drive from downtown Grand Rapids, which is why you will see visitors, but the crowd is mostly people who live inside a two-mile radius.

What is worth knowing is how programmed the evenings actually are. This is not a produce table and a folding chair. A representative Monday on the township calendar looks like this:

Live music from David Veenstra, David Dykstra, Max Morrison, or the In the Blue Jazz Ensemble from 6 to 7:30 p.m. Family Storytime at 6. Rotating food trucks including Airborne Burritos, Ohana Hawaiian Ice, Being Cheesy, Mexcellente, Irish Rovers, and Kona Ice. A Young Vendors Night where neighborhood kids sell their own products. Occasional programming like the John Ball Travelling Zoo.

Two practical notes for planning around it. The library shifts to summer hours after Memorial Day and closes at 1 p.m. on Saturdays, so if you were counting on a Saturday afternoon library stop, you are not. And parking behind the library gets used hard on market nights, which matters because the Clean Water Plant lot a few hundred yards north is closed for the summer. More on that in a minute.

What's Closed, What's Open, and Until When

The construction picture in Georgetown Township is denser than usual this summer. Rather than list it in prose, here is the schedule as of early July, pulled from the township's own project pages.

The Clean Water Plant closure is the one that reshapes weekend routines the most, because it takes out the easiest Kent Trails access point for the entire summer. The township is directing people to three alternates: Buck Creek Trail off Broadway Street in Grandville, Indian Mounds Drive in Grandville, and the Idema Explorers Trail entrance on Cottonwood Street in Jenison.

That last one is the interesting one.

The New Trail Loop Most Residents Haven't Ridden Yet

The Idema Explorers Trail has been on paper for years. Ottawa County describes it as a planned 36.5-mile non-motorized pathway that will eventually connect Grand Haven to Grand Rapids along the south side of the Grand River. About 16 of those miles are open, paved to 10 feet wide and ADA accessible, and dogs on leash are welcome.

The reason it matters this summer is a piece of trail that opened in September 2023 called the Jenison Mill segment, one mile long, marked at its east end by the Secchia Gateway Arch honoring Peter Secchia. That segment closed the last gap between the Ottawa County trail and the Kent County system, which means a rider or walker who starts at the Jenison Mill Trailhead at 7746 Cottonwood Drive is now connected to more than 100 miles of trail on the Kent side, including Millennium Park, downtown Grand Rapids, and the Grand Rapids riverfront.

For anyone who has not stitched it together yet, the working loop from Jenison looks roughly like this:

1. Start at the Jenison Mill Trailhead, 7746 Cottonwood Dr.
2. Head west on the Idema Explorers Trail along the south side of the Grand River.
3. Pass Grand River Park at 9473 28th Ave, where the annual Grand Explorers' Trail Race stages.
4. Continue to Grand Ravines Park, entering under the covered bridge on the way up to the river overlook where the resident bald eagles are usually visible.
5. Turn back the same way, or extend to the Bend Area Access Site at 8914 12th Ave.

There are five other Jenison-adjacent access points worth writing down, since the Clean Water Plant one is off the table until September: Grand Ravines North at 9920 42nd Ave, Grand Ravines South at 3991 Fillmore St, Grand River Park at 9473 28th Ave, the Bend Area at 8914 12th Ave, and the Jenison Mill Trailhead at 7746 Cottonwood Dr.

The Cottonwood entrance is the one that solves the summer Kent Trails problem, because from there you can cross the Secchia Arch and pick up the Kent County network without ever using the closed Baldwin Street lot.

Everything Else Still Running

A few smaller pieces of the Jenison week are unchanged and worth flagging, because with this much construction on the map it is easy to assume everything is disrupted.

• The Jenison Center for the Arts at 8375 20th Ave continues to run its summer concert schedule, and the venue has no posted age restrictions, so it fits most family plans.
• The Georgetown Senior Center soup and salad bar lunch runs Tuesday through Friday, 11:30 a.m. to 12:30 p.m., at $7 for one trip.
• Summer reading at the Georgetown Township Public Library is free and covers all ages, though remember the Saturday 1 p.m. summer close.
• Grand River Park is open as a race staging area and a river access point in its own right, not only as an Idema trailhead.

None of these show up in the county road bulletins because none of them are affected. That is the point of listing them.

How to Read the Rest of the Summer

If you take one thing from all of the above, take this. The construction is the loud story, but the quieter story is that the piece of infrastructure that changes daily life in Jenison the most is the trail, and the trail is mostly finished. A Jenison household that treated the Clean Water Plant lot as its default trail access last summer will spend this summer forced to try the Cottonwood entrance, and a lot of those households are going to keep using Cottonwood in September even after the Baldwin lot reopens. The construction is temporary. The route change it introduces to people's habits will not be.

That is the useful lens for the rest of the season. The Monday market is the anchor. The road closures are the noise. The Idema Explorers Trail is the thing worth learning while you have the excuse.

If you are thinking about where a home in Jenison sits relative to any of this, whether that is walking distance to the Baldwin Street market, a lot near a Cottonwood or 28th Avenue trailhead, or something quieter off Fillmore near Grand Ravines, the team at Bialik Real Estate knows this map street by street.
