Public Works Committee Meeting Date: 06/19/2018 Submitted For: Grant Riemer, Engineering/Public Works By: Grant Riemer, Engineering/Public Works 5. 1. Title: Consider Stop Sign Installation at Garnet St. and 169th Lane Purpose/Background: 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. Timeframe: 10-15 minutes Observations/Alternatives: 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
