South Campus Stormwater Detention Facility

University of British Columbia. Sustainability Office

SMC Engineering has prepared a detailed design report, as requested by UBC Social, Ecological, Economic Development Studies (SEEDS), of the UBC South Campus Stormwater Management System that intends to mitigate the key risks associated with the 1 in 10 and 1 in 100-year storm event. The detailed design report, further developed on the preliminary design report, provides the methodology and reasoning utilized for designing the optimal solution that curtails the risk of cliff erosion along Foreshore Trail and mitigates overland flow on the UBC campus. The report intends to provide UBC SEEDS with an understanding of the design, cost, schedule, and construction practices required to complete the methods of risk mitigation associated with the 1 in 10 and 1 in 100-year storm events. An overall site assessment confirms the physical aspects of the site such as topography, land usage, and the key constraints. A set of six studies are commissioned, which analyze the technical, economic, regulatory, environmental, societal, and constructability performance of the design solution. In particular, the environmental considerations regarding turbidity, infiltration, and long-term sustainability are detailed and cross-referenced with anticipated design performances. Engineering solutions component to the mitigation system that are not common in the UBC region have been researched thoroughly; the documented performances have been scrutinized with practicing engineering judgment in order to provide reasonable benefits with regards to the six commissioned studies. SMC Engineering has designed a system that consists of four detention tanks, a dry pond, and a system of permeable asphalt to manage, the 1 in 10 and 1 in 100-year storm events. The cost estimate and project schedule indicate that this system is estimated to have a total initial direct and indirect construction cost of $5,573,000 with construction slated to start on May 2, 2016 with substantial completion on October 14, 2016. The system is anticipated to have a 90-year design life, and a life-cycle analysis determines the maintenance and repair costs throughout its lifespan. Disclaimer: “UBC SEEDS provides students with the opportunity to share the findings of their studies, as well as their opinions, conclusions and recommendations with the UBC community. The reader should bear in mind that this is a student project/report and is not an official document of UBC. Furthermore readers should bear in mind that these reports may not reflect the current status of activities at UBC. We urge you to contact the research persons mentioned in a report or the SEEDS Coordinator about the current status of the subject matter of a project/report.”
