Corridor Redesign of Chancellor Boulevard Gillis, Gregg; Hamersley, Jackson; Hardie, Quinn; Houston, Damon; Mason, Erica; Naseri, Sina; Power, Sarah


Empire Engineering has prepared a design report for the redesign of Chancellor Boulevard from Drummond Drive to Acadia Road. Several key issues have been identified that have been addressed in the redesign. Due to insufficient traffic calming measures and the current road configuration, typical vehicle speeds in the project area exceed the posted speed limit of 60 km/h. The poor condition of the existing multi-purpose path and absence of safe pedestrian crossings limits pedestrian and cyclist accessibility and has resulted in these users taking alternative routes to access the University of British Columbia. Furthermore, the road is located near salmon-bearing creeks and sensitive ecological areas within Pacific Spirit Regional Park. Stakeholders have been considered throughout the project through consultation discussed in the Preliminary Design Report. The new road design includes one vehicle travel lane of a reduced width and designated bicycle lane in each direction, separated by rumble strips. This “road diet” approach will reduce travel speeds and also decrease the total impervious surface within the project area. To address additional forms of safe passage across the corridor, a precast concrete tunnel at the Spanish Trail head will be installed that provides space for both pedestrian and cyclists. This underpass will be equipped with accessible ramps, stairs, and lighting. Additionally, a marked crosswalk at the Pioneer Trail head will be added and equipped with a semi-actuated pedestrian crossing light. Pedestrians will also be able to access an improved and repaved multi-purpose trail along Chancellor Boulevard. Through the process of an Environmental Assessment, plans have been made to mitigate potential environmental issues that may arise during construction and operation. As such, a detailed Stormwater Management Plan has been implemented to increase the infiltration of stormwater into the natural groundwater. Empire Engineering estimates a cost of $6,146,000 for the remainder of the design and construction of this project. Construction is expected to be completed in 13 weeks, starting May 2018.
