Clearing and Grubbing

Clearing and grubbing is calculated by acre. When calculating facility costs, use the total acreage of the project that will be cleared of native vegetation.

How the Default Unit Cost was Determined

The Iowa Department of Transportation's Iowa Trails 2000 report estimated the clearing and grubbing component of trail construction at $2000 per acre. This figure was adjusted to $1,703 to reflect construction costs in 2002 in Ohio, the base line location for regional variations in construction costs.
