This report provides conceptual details for the redesign of the Chancellor Boulevard Corridor, from Acadia to Drummond Drive, upon the request of UBC Campus and Community Planning. The 1.8 km stretch of road that is being redesigned falls under the jurisdiction of the Ministry of Transportation and Infrastructure (MOTi). There are three key issues regarding Chancellor Boulevard that this project will aim to address. First, is addressing the excessive speeding along Chancellor Boulevard, and working to improve safety for all modes of transportation. Second, the new design must accommodate increasing travel demands as the university population grows. Third, the design will address existing pooling of water along the corridor. The redesign is split into three main sections: transportation design, structural elements at the underpass, and drainage re-evaluation. The design includes reducing Chancellor Boulevard from two travel lanes in each direction to one, allowing for the second lane to be converted to a protected bike lane. To encourage speed reduction, median and boulevard trees will be planted as well as reducing the width of travel lanes to 3.3 m, following Transportation Association of Canada (TAC) guidelines. These changes will allow for growth in all modes of transportation, and increase overall safety of Chancellor Boulevard. Minimal changes will be made to the Hamber Road intersection; however, conflict paint will be used to ensure clear cyclist right of way. A cast-in-place concrete pedestrian underpass will be constructed at the Pioneer trail providing safe crossing for cyclists and pedestrians. The median will be removed above the underpass to shorten the span of the tunnel and reduce construction costs. The tunnel will be accessible to all users and will span 9 m across. The crossing will be 5 m wide to promote usage and allow for dedicated bike and pedestrian lanes. Regarding the drainage design, the new system is designed to withstand a 5- year storm event, with 100-year events following the overland path on the road. A suitable catchment was determined, including design consideration to accommodate the golf course runoff located south of the roadway. The existing drainage infrastructure will be utilized, with minor pipe upgrades required. Installation of high capacity filter catch basins is recommended. This upgraded system will resolve the current issue of water pooling on the roadway. This project is estimated to cost $2.6 million. Construction is expected to take five months, with a start date of May 1, 2018.
