Challenge

NE 28th Avenue was a collector street in Hillsboro, OR, that had only two travel lanes and no bicycle lanes, sidewalks, or storm infrastructure. The corridor was the single crossing point of the TriMet Light-Rail line, connecting residential neighborhoods to the south with shopping centers and restaurants to the north. The challenge was to widen the corridor within a developed community, matching the fabric of the neighborhood.

Solution

Kittelson provided roadway design, signal design, traffic control plans, storm drainage conveyance and water quality design, landscape design, survey, geotechnical design, Level 1 hazardous materials assessment, and specifications and construction cost estimates. To aid in community engagement and the right-of-way process, we created 3D renderings of the improvements, which allowed us to convey clearly how public input was incorporated into the design as well as display precise images of the designed project.
