Understanding and Assessing Impacts
The Black Creek neighbourhood is home to a diverse population of about 25,000 residents. It is made up of high-rise residential buildings and single-family homes, as well as commercial and institutional developments.
The SNAP action plan undertook a number of analyses to better understand the Black Creek Study Area and how it will be affected by future climate. A Neighbourhood Profile compiled information on land use and demographic information including age and income, recent immigration, home language, and rental and ownership rates, as well as the amount of paved and unpaved surfaces, urban forest analysis, and an urban heat island mapping. An energy use analysis and stormwater modeling was also undertaken. The SNAP team conducted an analysis of growing requirements for fresh vegetables and the plantable area in the neighbourhood, and found that 20% of the area’s open ground can provide 20% of the community’s vegetable needs, with additional opportunities at the balcony and rooftop level. A tree planting opportunity analysis looked at space availability and calculated number of trees required to achieve the city’s urban forest goals.
The Humber River Watershed Plan, Pathways to a Healthy Humber assessed future climate, geology and landform, groundwater, surface water quality and quantity, stream form, air quality, aquatic and terrestrial systems, cultural heritage, nature-based recreation, land use, and resource uses in the community and greater GTA.
The City of Toronto’s Wet Weather Flow Management Master Plan identified the Black Creek neighbourhood as a site of basement flooding concern and is interested in promoting basement flooding prevention measures and lot-level stormwater management practices such as downspout disconnection, rain harvesting and permeable pavement in driveways to reduce the strain on the storm sewer system. Climate impacts identified by SNAP include rising temperatures and urban heat island effects, high volumes of stormwater runoff and flooding due to more frequent extreme weather events, and water shortages due to drought.
