St. Cloud  Minneapolis  St. Paul Equal Opportunity Employer wsbeng.com Technical Memorandum To: Diane Hankee, PE Copy: Michael Grochala City Engineer Community Development Director City of Lino Lakes City of Lino Lakes From: Chuck Rickart, PE, PTOE File: WSB No. 2029-240 Principal/Traffic Engineer Date: June 28, 2017 Subject: Arlo Lane Stop Sign Supplemental Review A Stop Sign review of Arlo Lane was presented to City Council at their work session on June 5th, 2017. Based on the review of the intersections including the traffic characteristics and the requirement found in the MnMUTCD it was concluded that; the traffic conditions in this area have typical volumes for residential streets and, the intersections do not meet the warrants for all- way stop sign installation. Based on the conclusions the following was recommended: 1. No change in existing traffic control. 2. Continue to provide police presence in the area. 3. Traffic control at the intersection should continue to be monitored and, if at any time there are demonstrated safety concerns, the City should reevaluate the installation of the intersection control. At the meeting several residents were concerned with the location and time frame in which the traffic data was collected. It was agreed that updated traffic volume and speed counts would be conducted to insure that the traffic conditions were completely documented. Additional data was therefore collected at two locations on Arlo Lane, one west of Joseph Court (approximately 300 feet) and one east of Highland Drive (approximately 200 feet). The data was collected from Friday June 9th through Tuesday June 13th. The attached Figure 1 shows the count locations. The results of the additional data collection are shown below in Table 1 for traffic volumes and Table 2 for speed data. The data is shown for each day the data was collected including the data collected in April from the previous study.
