Date: December 5, 2018 To: Bruce Westby, P.E. From: Kevin Kielb, P.E. Bryan Nemeth, P.E. Subject: Bunker Lake Boulevard and Puma Street Intersection Control At the request of the City, we are providing information related to the intersection traffic control at Bunker Lake Boulevard and Puma Street. The intersection control installed with the recent street reconstruction project includes an All Way STOP. INITIAL INSTALLATION Bunker Lake Boulevard and Puma Street are State Aid routes. During the plan approval process, these were the only legs of the intersection constructed, with Rabbit Street depicted as a future roadway. Because the travel path from Bunker Lake Boulevard to Puma Street doesnt meet a 30 MPH design speed, STOP signs were required to be placed on these two intersection legs. A third STOP sign was depicted on the plans for Rabbit Street to complete the All Way STOP. BACKGROUND The Bunker Lake Boulevard and Puma Street intersection was one of the intersections reviewed as a portion of the Business Park Analysis. In the March 2017 Business Park Report Update, two types of control were reviewed for the intersection: Roundabout, and · All Way STOP. · Both were found to be adequate for the anticipated short-term traffic volumes and long-term growth in the corridor. TRAFFIC PATTERNS VS SAFETY The primary traffic in this area will be along Bunker Lake Boulevard and Puma Street, with lesser traffic on Rabbit Street. Because of the intersection configuration, the primary traffic patterns end up being secondary to safety concerns. This is addressed in the MUTCD, 2B.4 Right-of-Way at Intersections. YIELD or STOP signs should be used at an intersection if one or more of the following conditions exist: A.An intersection of a less important road with a main road where application of the normal right-of-way rule would not be expected to provide reasonable compliance with the law.
