COMMITTEE BUSINESS (Continued) 5.02: Consider Request to Modify Traffic Control at Bunker Lake Boulevard, Puma Street and Rabbit Street Intersection th City Engineer Westby stated that during the November 27 City Council meeting, a resident living at 14942 Quintana Street NW in the Riverstone residential development questioned the value of the all-way STOP intersection control recently installed at the intersection of Bunker Lake Boulevard, Puma Street and Rabbit Street, and requested that the City consider modifying the traffic control at this intersection. The resident told Council he feels the all-way STOP is unnecessary at this time and recommended that all of the STOP signs be removed and replaced with a YIELD sign on southbound Puma Street. He said he also felt that said a flasher signal might be appropriate for the pedestrian crossing at the intersection. He then stated that during the five-months he has lived in Riverstone he has never met another car at this intersection, nor has he ever seen a pedestrian or bicyclist use the crosswalk. He also stated he often sees Riverstone residents running the STOP signs and is concerned people will get used to running the STOP signs and will continue to do so once the area more fully develops, and the STOP signs are warranted. City Engineer Westby provided historical crash data for the intersection and reviewed the posted/statutory speed limits on each leg of the intersection. He also reviewed the traffic volumes which were most recently recorded on each leg of the intersection in 2015. City Engineer Westby stated that staff discussed the property owners concerns with Bolton & Menk, the design engineer for Improvement Project #18-05 under which the STOP signs were installed. Bolton & Menk stated that the all-way STOP control was based on the best information available at the time related to intersection geometrics and traffic volumes in and around the intersection at the time it opened. Throughout the plan preparation process, Rabbit Street was still considered a future street and in order to obtain State Aid approvals, STOP signs were required on both Bunker Lake Boulevard and Puma Street. Development timing and the resultant traffic growth were unknown at the time plans were developed, and traffic forecasts were aggressive. Growth in the area will dictate when an all-way STOP control is warranted. Public Works Committee / December 18, 2018 Page 9 of 11
