The Parking Lot Math Nobody Wants to Run

From the street, the Glen Ellyn strip center looked well-managed.

Six tenants, solid occupancy, professional signage. The kind of property that rarely came up in ownership conversations because it mostly ran itself.

But during a late-March exterior review, the picture changed.

Three years of deferred pavement maintenance had caught up in the span of one winter. What had been minor surface cracking was now a 40-foot stretch of deteriorating asphalt near the main tenant entrance — with two potholes deep enough to require ADA documentation, faded accessible parking markings, and a dumpster enclosure pad that had developed a drainage pitch toward the building.

The estimate came back at $38,000.

The estimate for the same work three years earlier: $9,200.

This is the math nobody wants to do — but every property manager should run once a year. Deferred pavement maintenance doesn't stay deferred. It compounds.

1) Get the restripe on the calendar

Line restriping requires dry pavement above 50°F. The weather window for DuPage County is open right now. Accessible space markings are a compliance requirement, not a preference — and if a tenant, vendor, or inspector catches faded markings before you do, you've lost the initiative.

2) Do the ADA walkthrough yourself first

Walk every accessible stall, curb cut, and path of travel from the accessible space to the building entrance. Document everything with timestamps. If you find a violation, you want to find it before anyone else does — and you want a record that shows you were proactive.

3) Schedule drainage improvement conversations now

If your property has standing water after a normal rain event, that's not a weather problem — it's a grading or drainage problem. Summer storm patterns in the Chicago suburbs will test every weak drainage point you have. Getting a civil contractor to look at it now costs a fraction of what it costs after a flooding event.

The property managers in DuPage County who keep maintenance costs predictable tend to run their spring exterior restoration in a specific order. Pavement repair goes first — sealing and patching before the heavy traffic season. Concrete cleaning and treatment follows. Building facade washing comes last, so you're not cleaning a surface that's about to get disrupted by nearby work.

Getting the sequence right means each service builds on the last, and you're not re-cleaning something that should have been done second.

Q: When is the right time to restripe a parking lot — before or after sealing?

Always after sealing, if you're doing both. Sealcoating covers existing striping, so any restripe done before the seal will be buried. The sequence: pothole patching and crack repair first, sealcoating second, restripe last.

If you're not sealing this cycle, restripe when temperatures are consistently above 50°F and you have at least 24 hours of dry weather ahead. For DuPage County, late April through early May is the sweet spot.

One thing that trips up a lot of properties: accessible space requirements are more detailed than a basic repaint. Stall dimensions, access aisle widths, signage placement, and surface slope requirements all have specific standards. If your accessible spaces haven't been reviewed in a few years, include an ADA compliance check when you schedule the restripe.
