The proposed design includes the construction of a stormwater detention facility under the field along with a two storey underground parkade under the stadium building. Collected stormwater is stored under the field and diverted to a water treatment system. The treated water will be distributed to the stadium and the botanical garden and reused for irrigation and flushing toilets. The stored water can also infiltrate into the native soils and act as a groundwater recharge source. In case of an extreme event corresponding to a 10-year and a 100-year return period, water can be diverted to the lower level of the parkade which serves as a secondary water tank and discharged through the UBC's current pipe network. This design is effective and efficient to properly deal with the UBC's current concern related to stormwater management and prevention of floods and potential slope stability around Point Grey. The demands and capacities of the parkade were analyzed using software such as S-Frame™, S-Steel™ and S-Concrete™. The loads on the structure are composed of the dead load, vehicles load, exit load, soil pressure and snow load. The steel sections and rebar of this structure were chosen based on the CSA S16-14 and determined to be 350W and 400W respectively. The preliminary schedule for the project indicates a start on May 1st, 2019 and completion in October 2019; a total of 6 months. Additionally, the report reviews a detailed cost estimate including first costs, annual operating cost, and maintenance costs. The total expected cost is estimated at CAD $15.7 million for the parkade, detention tank and accompanying facilities construction. The parkade and water storage facility is mindful of the local environment and stakeholder interests.
