Consider Stop Sign Installation at Garnet St. and 169th Lane

Staff has received a request for stop signs at the intersection of 169th Lane and Garnet St.  Currently there are no stop signs on any legs of the intersections. The requested action would change this intersection to a 2-way stop, with the stop condition on the north and south legs of Garnet Street. The reasons given for requesting the additional stop signs are excessive speed and there is a bus stop located at that intersection. The neighborhood petition requesting the stop signs is attached to this case.
 We used the police radar trailer to gather information on vehicle speed and to determine the  85 percentile speed.  The 85 percentile is defined as " “the speed at or below which 85 percent of all vehicles are observed to travel under free-flowing conditions past a monitored point.” The trailer was in place May 16,17,21,24 and the 29th.
 

10-15 minutes

The following information was gathered at the intersection:
Traffic count on Garnet St  north of 169th Lane-447 ADT
Traffic count on Garnet St south of 169th Lane -267 ADT
Traffic count on 169 th Lane east of Garnet St-104 ADT
Traffic count on 169 th Lane west of Garnet St -338 ADT
Posted speed limit at intersection-30 mph
85th percentile speed- 37.52 mph
Accident data- no accidents reported for this intersection

Based on the information gathered, this intersection does not meet the warrants outlined in the Minnesota Manual of Uniform Traffic Control Devices because of the following factors:
1. Insuffcient traffic volumes
2. Accident history at the intersection
3. Sufficent visability at the intersection










 
 

 

This case was prepared as part of normal Staff duties.  Any signs recommended for installation would come from the general fund budget.

Staff recommends not  installing additional stop signs at this intersection based on the traffic counts and accident history.  Staff would also recommend that the Police Department continue to enforce the 30 mph speed limit in the area in an effort to reduce speeds on Garnet St.

Motion to accept staff recommendation to not install additional stop signs at 169th Lane/Garnet St based on the traffic counts, visibility and accident history  or reject staff recommendation and approve alternative motion based on committee discussion.
