Description | Red Fish Blue Fish Consulting (RB Consulting) was retained by UBC SEEDS to undertake the detailed design of the intersection st Chancellor Boulevard and East Mall. Expectations for the redesigned intersection included: improved safety and accessibility for all users, it would act as a gateway to UBC, accommodation of growth, and a focus on sustainability. It is assumed that the reader has access to past reports completed by RB Consulting related to this intersection. Enclosed are the final detailed drawings, along with all key information about the design. The design consists of a single-lane roundabout with a separated bike lane, rain gardens in the medians for runoff catchment, and a glued laminated timber (glulam) Welcome Archway spanning the West entrance of Marine Drive. The consulting team has completed a detailed economic analysis of the project in order to provide a cost estimate of $1.1 million and an expected contractor schedule of two and a half months. The angled orientation of the intersection will reduce vehicle speeds, and the probability of collisions by having fewer conflict points than the existing or possible signalized layouts. With a separated bike land and simplified crosswalks, this intersection will encourage sustainable travel modes and also increase safety for those users. Emissions and noise will be reduced by the new intersection from minimal idle times, enhancing sustainability and the local community. Furthermore, the footprint of the intersection reduces the overall impervious surface, while the rain gardens are designed to capture all of the remaining runoff from the intersection. Lastly, the Welcome Arch will highlight sustainability with locally-sourced, environmentally-friendly glulam material, and includes additional features that support the local animal habitat. Prior construction at the intersection the following need to be provided to confirm design assumptions: geotechnical report, survey data, and exact underground utility locations.
