A. Issue
Visual obstructions may block lines of sight and may not allow a road user to yield or stop in compliance with the normal right-of-way rule.
B. Background/Options
The City has adopted a policy that follows national standards related to the installation of yield and stop signs. The policy allows residents to request consideration for stop signs when they believe a condition, as described in the Manual on Uniform Traffic Control Devices (MUTCD), has been met. Staff received a request for stop control at the 75th Street & Portland Avenue intersection and analyzed if such traffic control is warranted.
75th Street & Portland Avenue is a four-leg intersection with a 60-degree skew and operates under no control (normal right-of-way rules). Both streets have statutory speed limits of 25 mph. 75th Street is approximately 30-feet wide and Portland Avenue is 36-feet wide. The intersection was analyzed to determine if yield control or two-way stop control is warranted at the intersection. The results are below.

Traffic Volumes
The combined volume of all vehicular, pedestrian, and bicycle volume entering from all approaches averages more than 2,000 units per day.

Vision Issue/s
Ability to see conflicting traffic on an approach is not sufficient to allow a road user to yield or stop in compliance with the normal right-of-way rule.
Houses in all four corners of the intersection result in insufficient sight distance for an intersection operating under no control. 60-degree intersection skew exacerbates vision issues.

Crashes
The intersection has 3+ crashes over a two-year period or 5+ crashes in a three-year
period susceptible to correction...
