The City of Silverton, Oregon plans to widen and rehabilitate McClaine Street, a minor arterial road that connects the historic downtown with a commercial district on the west side of the city. The project area is the portion of road between the intersection of McClaine and Trix St. at the northwest corner and the intersection of McClaine and West Main St. at the southeast corner (Figure 1). This section of McClaine has severe deterioration, an inadequate sanitary sewer system, and no stormwater management system. The City of Silverton’s goals for the project are to improve the overall quality of life for residents who live on and travel through this section of McClaine Street. The road also needs to meet future demands of the growing city population. The project team’s design objectives are pedestrian, bike, and vehicle safety and accessibility; effective low impact stormwater management; and efficient, safe intersections. The team is composed of three transportation engineers to focus on the road design and traffic, and two water resource engineers for the stormwater management system design.
The final design of the project includes the realignment of McClaine road splitting into two 10 foot lanes leaving space for a multi use path along the west side of the street and a sidewalk on the other side. In addition, the intersection of McClaine Street and Main Street will be redesigned into a signalized intersection equipped with phasing for pedestrian crossings and radar detection for vehicles. The last transportation improvement will be the addition of speed radar and traffic signs to improve safety of the arterial road. The water resources team will add a new stormwater management system including structural infiltration basins and drains along the road connected to a new storm water line connecting from Main Street to existing infrastructure further down McClaine Street.
