| This federally funded $4.0 million TIB roadway improvement project took place along the 220th Street corridor—a critical east-west arterial connecting Edmonds to I-5. The existing road, with its open ditches, lack of sidewalks, poor vertical sight distance, and close proximity to two elementary schools, was in desperate need of safety improvements. Public opposition for the project was high with the fears of a three-lane highway cutting through the well-established residential neighborhood.
Using the charrette process and a strong community involvement program, we balanced the project’s safety improvement with the citizens’ concerns. The residents worked alongside the engineers to develop a narrow roadway section of two lanes with left turn pockets at key intersections. Following the charrette, numerous residents spoke in support of the project at a city council presentation.
The project incorporated unique safety features including a pedestrian activated crossing with in-pavement lighting, permanent radar speed signs and gateway landscaping treatment to slow traffic. Other project improvements included innovative water quality treatment to reduce right-of-way impacts and construction costs for the six drainage basins along the corridor. Coordination between the utility companies ensured that the project met the critical schedule.
We performed a variety of services during the project—survey, roadway design, storm design, signal design, public involvement, value engineering, right-of-way, construction management and construction staking.
