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.

 

Yield/Stop Criteria

Minimum Threshold

75th Street & Portland Avenue

Threshold Met?

Traffic Volumes

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

Traffic volumes were not collected

Unknown

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.

Yes

Crashes

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

Records show zero reportable crashes at this location within the past three years that may be susceptible to correction by yield or two-way stop control.

No

Two-way stop control is warranted and necessary for motorists to properly see conflicting traffic. It is recommended to install the stop signs on the 75th Street approaches to Portland Avenue.

 

Approximate Location of Recommended Stop Signs

 

C.                     Strategic Plan (Area of Focus)

Priority 2: Public Safety, Goal 2. Proactively address pedestrian, bicycle, and vehicular safety

 

D.                     Fiscal Impact

Minor expenses for the in-house creation and installation of signs. The existing sign budget will

accommodate these expenses.

 

E.                     Recommendation

Direct staff to initiate a 90-day trial to install stop control on the 75th Street approaches to Portland Avenue
