“The total cost of the project exceeds our annual budget,” Dodd said. “This will more than likely happen in phases with the final phase being the addition of the sidewalk along the entire corridor.”
The report to the city is based on a study where engineers examined about a 300-foot portion underneath Little Sugarcreek Road. The east side of that portion of the roadway sunk by about 12 inches after a period of heavy rainfall, which led to travel restrictions on commercial trucks. City crews temporarily fixed the damaged area by back-filling it with gravel.
The study, which cost the city $24,800, indicates the bedrock slipped underneath the roadway where the damage occurred.

The permanent solution, as recommended in the study provided by Engineer Dan Hoying, is to install three-foot and two-foot alternating pillars into the bedrock. The pillars must be driven about eight feet into the bedrock, and more borings into the soil are needed to determine exactly how deep the bedrock is from the surface.
Dodd said costs to do more borings will be factored into the city’s 2020 budget, adding that the additional work will help determine more precisely the total costs of the project.
