Current Seal Coating Schedule

Listed below is the current schedule for seal coating.  The schedule can be affected by weather and is subject to change. 

Sealcoating work will resume in 2019.

Tilling Process

Tilling is a process of grinding and mixing the existing road surface and base. Additional gravel is then added to the existing material and all the materials are compacted and graded. The process takes several days and traffic is also used to help compact the gravel. Once the gravel is compacted, the road is graded one more time, and seal coating of the road occurs.

Tilling work will resume in 2019.
