Chip Seal


Every year in Overland Park, maintenance treatments are applied to designated streets throughout the city. About 200 miles of streets are treated, impacting about 10,000 residents.


Generally, the chip seal program begins in June and is completed in September.

During the process, streets will not be closed and you will have access to your home.

Chip seal consists of spraying a mixture to seal cracks then spreading small chip rock, followed by rollers to embed it into the street surface. The process takes less than one hour per street and up to 24 hours to completely cure. You can slowly drive over the surface during the curing process.

Your street will be swept five times to reduce loose rock after application. The first four sweeps will be completed by the contract crew: Twice within the first week after application, once the following month and then a fourth time two months after application. City crews will sweep your street a fifth time as part of an annual fall sweep.

On the scheduled day of work, please do not park any vehicle on the street. We also request you not park any vehicle on your street for a week. This allows street sweepers to effectively remove loose rock chips.

The weather, mechanical problems or other delays may prevent completion of your street on the scheduled day. If this happens, you will receive notification at least 24 hours prior to sealing of your street.

In an effort to ensure that residents have sufficient advanced notification prior to the work, postcards are mailed approximately one to two weeks in advance. Door hangers are distributed 48 hours in advance throughout the neighborhood detailing on which day work will occur. The postcards and door hangers will provide a telephone number that residents can call with questions or concerns.

To report a problem, submit a help request through OPCares, the city's customer service system, with a description of the problem, location and any other pertinent information.

Why Chip Seal?

Chip seal extends the life of the street, provides a good driving surface, is relatively quick to apply, thereby, decreasing the inconvenience to you, and it lasts longer than other methods that are not nearly as effective and are more expensive.

Taxpayer dollars:
  • For every $1 spent on the chip seal application, taxpayers would have to pay $6-$10 for asphalt overlay. Or to say it differently, doing an asphalt overlay application to the streets would cost up to 10 times more than the chip seal method.
  • A lane mile of chip seal application costs $17,600 compared to $176,000 per lane mile for asphalt overlay. An asphalt overlay lasts about 10 years while the chip seal application lasts approximately seven years before needing to be re-applied.
  • A $250,000 home pays $1 per month in taxes for all street maintenance.
  • The cost to reconstruct a street lane mile is about $1.5 million. The Overland Park plan is to keep streets well maintained and preserved with the best methods available so they will not need to be reconstructed.
  • We are keeping streets in good condition and from deteriorating by sealing cracks in the pavement. Sealing prevents water intrusion (water seeping under the pavement) and provides a moisture barrier; this is moisture that causes damage and deterioration to the foundation. It's easier, better and more cost effective to "keep good streets good."
  • The chip seal application will last an average of seven years before it needs to be treated.
  • By placing a chip seal sooner than an asphalt overlay would be placed, the traveling public benefits from roads maintained in better condition.
  • Chip seal provides a skid resistant surface that may be used right after application.
  • It's important to drive slowly and attempt to avoid braking and turning wheels sharply for parking within the first few hours after application.
  • The only time you are not able to walk or drive slowly over the surface is during the application of oil.
  • Residents in areas receiving chip seal will receive a postcard that their street is going to be treated. A second postcard will be sent a week or two prior to the work as a reminder, and to remind everyone not to park vehicles on the street the day crews are scheduled to work.
  • A door hanger will be left at homes as a final reminder.
