Spring Potholes Where a Lansing Driveway Meets the Street
The apron takes the plow, the gutter water and every turning tire, so it is a likely place for a spring pothole to open, and fixing it properly starts with knowing whose pavement it is.
Why the street end takes the hardest wear
The apron, the few feet of pavement between the street and the main body of a driveway, carries loads the rest of the drive rarely sees. Every car turns across it at an angle, delivery trucks swing their rear wheels over its edge, and plows push snow against it all winter. It also sits beside the gutter, where meltwater runs and pools. In a normal year the airport station northwest of downtown records about 80 freeze-thaw days, with March the peak at 17.8, and the apron is where water, weight and those crossings meet.
Local snow rules explain why so much of it piles up there. East Lansing plows residential streets once more than three inches has fallen, and DeWitt asks residents not to shovel, blow or push snow back into the street, so the windrow left by the plow is cleared onto the apron and the lawn beside it. When that pile melts on a sunny March afternoon and refreezes overnight, the water works into the joint between street and drive and into any crack nearby.
Underneath, the thaw does the rest. Pavement Interactive explains that the ground under a thawing drive gives up much of its strength, because meltwater is trapped above soil that is still frozen, and it cannot drain until that lower layer thaws too. A tire turning over softened ground in March is the load that turns a crack into a hole, and the apron gets more of those turning tires than any other part of the drive.
First question: whose pavement is the hole in?
Before anyone patches, it helps to know where the road agency's pavement ends. Inside the city, streets belong to Lansing's Public Service Department, which is responsible for 107 miles of major streets and 303 miles of local streets and runs a potholes page for reporting holes. In Meridian Township, MDOT owns Grand River Avenue and Saginaw Street and the Ingham County Road Department owns the other public roads. East Lansing and DeWitt maintain their own streets.
Michigan's Act 200 of 1969 makes a driveway onto a county road or state trunkline lawful only under a permit from that road's agency, and cities regulate driveways on their own streets. East Lansing requires its right-of-way application, filed online, for work in the street right-of-way. DeWitt's right-of-way application requires 24 hours' notice to the public services supervisor, limits working hours, requires paved streets to be bored rather than cut unless the city allows otherwise, and directs applicants to call MISS DIG before digging.
The practical rule is simple. A hole in the street itself is reported to the agency that owns it. A hole in the driveway is the owner's to repair. Anything that cuts into the street, the curb or the approach within the right-of-way should wait until the agency has said yes.

Holding repairs in March and April
A pothole that opens in March is hard to fix properly in March. The ground under it is thawing, the hole is wet, and the weather is too cold for hot mix to compact and cure well. What can be done is a holding repair: clean out loose pieces and water, tamp cold patch into the hole firmly, and mark the spot so it gets a real repair later. Cold patch is made for exactly this, placed without heat in cold, damp conditions, and it should be treated as temporary.
The same months call for keeping heavy loads off the apron. Michigan lets road agencies reduce maximum axle loads during March, April and May, by 25 percent on concrete and 35 percent on all other types of roads, because thawed ground cannot carry full weight. A driveway gets no such protection, so a loaded moving van, a roll-off dumpster or a concrete delivery booked for April can press a softened apron into the base. If one cannot be moved to summer, boards under the dumpster rails and a route over the thickest pavement reduce the damage.
March and April are also the time to photograph the damage. Pictures taken while the hole is fresh, with a tape measure in the frame, make it easier to compare contractors' written scopes later and to see whether the damage spread before the permanent repair.
The permanent patch after the thaw drains
The real repair belongs after the ground has drained, which around Lansing means after the May 2 median last frost. Angi's curing guide gives 50 to 85 degrees as the range in which new asphalt dries and cures well, and the airport station's normal highs are 68.8 degrees in May and 78.4 in June, so late spring is when hot-mix work can proceed with confidence.
A lasting apron patch removes more than the hole. Pavement Interactive's repair note for localized fatigue cracking is to remove the cracked pavement, dig out and replace the poor subgrade, improve drainage and patch, and it notes that this plated cracking can deteriorate into potholes, so the cracked pavement around a hole is part of the job. In practice that means saw-cutting a rectangle to sound pavement, digging out wet or soft base, rebuilding it with compacted gravel, coating the vertical edges with tack so the new asphalt grips them, and placing hot mix in compacted layers. The asphalt patching page compares that full-depth method with hot-mix fills and infrared repairs.
Drainage is part of the patch. If gutter water backs up onto the apron, or a downspout empties across it, the new base will be wet again next March. Regrading the lawn edge below the pavement, extending downspouts and filling the joint between patch and old pavement with crack sealant all keep water out of the rebuilt section.
Sealing the apron with the rest of the drive
New asphalt should cure before it is coated. SealMaster puts the minimum at 30 to 60 days and Angi suggests up to three months, so an apron patched in May or early June can usually be sealed with the whole drive in July or August, while a patch placed in September is better left uncoated until the following summer. Sealing the whole drive at once, rather than the patch alone, gives even color and protection.
Aprons meet public curbs and sidewalks, so the edges need care. SealMaster's application guide says to cut in the edges first so sealer stays off curbs, sidewalks and adjoining surfaces, and to keep traffic off for at least 24 hours. In East Lansing, the product also has to meet the city's listed limit of 0.1 percent PAH content, which rules out coal-tar sealers. For the full sequence of repairs through the season, the pothole season guide lays out the calendar, and the home page covers sealcoating in Lansing more broadly.

Quick Answers
Can a homeowner patch the apron where it meets a county road?
Repairs inside the driveway are the owner's business, but the end nearest the street typically lies in the road right-of-way, which is why DeWitt handles driveway and culvert replacement through its right-of-way application. Michigan's Act 200 of 1969 requires a permit from the road agency for driveways onto county roads and state trunklines, and East Lansing and DeWitt require right-of-way applications for work in their streets. Anything that cuts into the street, curb or approach should be cleared with the road agency first.
Should an apron be sealed while the street beside it is breaking up?
Sealing the drive does nothing for the street, and the street is not the owner's to seal. Report the street pothole to the agency that owns the road, and seal the drive on its own schedule once any patches have cured. SealMaster's guidance to cut in the edges first keeps the coating off the curb and gutter, so the drive can be sealed cleanly even if the street waits.
When is the earliest a permanent apron patch can go in?
Once the thaw has drained and the weather is warm enough for hot mix, which around Lansing usually means May, after the May 2 median last frost. Angi puts the favorable range for new asphalt at 50 to 85 degrees, and the airport station's normal high climbs from 57.8 degrees in April to 68.8 in May. A cold patch can hold the hole until then.
