DISCUSSION AND POSSIBLE ACTION REGARDING REQUESTED ALL WAY STOP INSTALLATIONS AT THE INTERSECTIONS OF DIAMOND/GERTRUDA AND DIAMOND/GUADALUPE
end
EXECUTIVE SUMMARY
In response to a resident request, staff is bringing forward a discussion regarding all-way stop ("AWS") controls at two adjacent intersections, Diamond Street & N Gertruda Avenue and Diamond Street & N Guadalupe Avenue. In accordance with the City Council's policy for AWS requests, staff initiated a survey of residences within 150 feet of each intersection and received insufficient resident support to carry either intersection forward on those grounds. The City's Transportation Engineer performed a sight distance and safety evaluation at both intersections and engineering analyses in accordance with the California Manual on Uniform Traffic Control Devices (CAMUTCD). Based on those analyses, staff did not find any justification to install AWS controls at either intersection. In addition, staff strongly recommends against the installation of AWS controls at either intersection per the CAMUTCD. Under normal circumstances, the City Council's AWS policy does not require further public discussion of AWS requests if they do not meet either the resident survey or engineering analysis thresholds. Due to public comments received during this request and after discussion with the councilmember for District 2, staff has brought forward these two AWS requests to the Public Works and Sustainability Commission (PWSC) for public input and discussion.
