Siksin Consultants Ltd. has been tasked with developing a mixed solution of a car parkade and stormwater management system project to mitigate extreme flooding that may occur in a 1 in a 100-year storm event around the area of Marine Drive and West 16th Avenue, Vancouver. The goal of the design also includes creating a neighborhood welcoming atmosphere recreational area for the future neighborhood development. On the surface, the parkade, bioswales, skate board park and amphitheater act as a part of the stormwater collecting system. In an extreme storm event, the skate park and amphitheater are intended to hold and temporary store stormwater to help slow down rainfall runoff and prevent erosion at the cliff. Under normal weather circumstances, precipitation is collected from the car parkade to the bioswales along the current slopes down to the field. The bioswales serve to control the runoff flow rate and act as a natural filtration system. The collected water then travels through underdrain beneath the bioswales and is stored in the underground retention pipe system. An UV filtration system is also installed for water purification purposes. Once the storage tanks have reached its capacity, additional water is left at the various collection points for natural infiltration and evapotranspiration or transported directly to the sea through existing pipes. The existing car parkade is also revamped. A solar panel roof is added to provide renewable energy to the stormwater management system, in particular, supply energy to the pump. The current concrete ground is replaced by permeable porous asphalt to help infiltrate stormwater and additional storm drains will be placed for extra drainage. The car parkade capacity is reduced to 80 spots to encourage the use of alternative sustainable transportation methods.
