Purpose & Explanation
As a follow up to the recently completed Downtown Pedestrian Safety Study and other on-going improvements near the City’s Historic Greens and intersection, City Council requested a discussion regarding the existing turn radius at the SR 91 and SR 303 intersection and the impacts of turning vehicles, especially trucks, overtopping the curb/sidewalks at the intersection.
In preparation for the discussion, staff reviewed a previous traffic study that included an evaluation of the SR 91 and SR 303 intersection, evaluating accident data, potential congestion mitigation and geometric improvements including lane widths, signal pole layouts and the turn lane radius. It was noted in the study, that to fully accommodate semi-trucks, impacts to the downtown Greens would occur. To avoid impacts to the Greens, the study identified that the existing, back edge of the sidewalks would not be shifted as to minimize impacts. The final recommended layout identified in the study is shown on Exhibit A.
Based upon discussion with City Council, City staff will further evaluate measures to the intersection to improve pedestrian safety.
