ODOT selected Palmer Engineering to complete a 1-mile preliminary engineering study for drainage improvements and widening of US-20 in a suburban area.
Existing storm sewers were inspected and checked for capacity. Widening scenarios were developed and evaluated for impacts to adjacent properties and utilities. Since the fieldwork showed evidence of worn paths from pedestrian traffic, a sidewalk analysis was incorporated into the project. Right-of-Way estimates and cost estimates were developed along with reports and preliminary engineering plan sets.
