Prior to beginning the Neighborhood Congestion Reduction Program in 2017, there were a limited number of projects that had been studied and had concepts developed for addressing congestion issues. A list of potential projects was created based on community input and prior planning studies. These projects were ranked based on scoring criteria developed with the support of the Transportation Commission. Studies of the top ranked projects were kicked off in 2018.
At its September 26, 2019 meeting, the Transportation Commission considered recommended projects intended to reduce neighborhood traffic congestion. Staff presented a summary of findings and results of the project scoring based on criteria previously established by the Commission. Scoring the projects helped to prioritize projects but does not guarantee projects will advance. Packet materials from meeting are below:

Eastgate Transportation Study
City staff and consultant team worked with the Transportation Commission and the Eastgate community to identify near-term projects to address congestion in Eastgate. The result of this effort is the Eastgate Transportation Study, published in July 2019. The study describes how the potential traffic congestion reduction projects were identified, evaluates the performance of the projects with a range of metrics from a multimodal perspective, and prioritizes the projects for potential early and long-term implementation.
