Understanding and Assessing Impacts
Several documents and reports, prepared by Durham County, The City of Oshawa, and the Central Lake Ontario Conservation Authority (CLOCA) provided the basis for carrying out a municipal asset inventory.
In 2016, Durham County, the upper-tier government in which Oshawa resides, developed the Durham Community Climate Adaptation Plan. As part of this plan, Durham County employed SENES Consultants to identify the top climate risks to the County as a whole and to lower-tier municipalities. This information was reported in Durham Region’s Future Climate Report (2040-2049), which details climate change projections for Durham Region in the period 2040 to 2049 compared to the past (2000 to 2009) based on the IPCC’s Fourth Assessment Report A1B scenario. Oshawa is expected to experience increases in seasonal and annual temperatures, increases in annual and seasonal precipitation as well as an increase in the frequency of extreme weather events.
The City of Oshawa prepared a Strategic Plan for 2020-2023 identifying high-priority goals to guide decisions made by the City. Identified in this plan were strategies to protect, conserve, and promote the environment. These strategies include:
- Identify, connect, and protect natural heritage features, areas, and habitats including the city’s urban forest canopy
- Identify, evaluate and implement adaptation measures to strengthen the city’s resilience to a changing climate, invasive species and other stressors
- Ensure City policies and practices, including stormwater management, respect and enhance the natural environment
- Encourage and implement actions to continue to improve water quality and water aquifers
- Promote the remediation of contaminated land and brownfield developments
Additionally, as per O. Reg.588/17, the City of Oshawa has already undertaken an asset management plan that supports its strategic direction and complies with the province’s regulation.
The Oshawa Creek Watershed Plan developed by the Central Lake Ontario Conservation Authority (CLOCA) is the primary source of information on the current condition of the creek and its upstream watershed. The Oshawa Creek Watershed Plan speaks to the conditions of the entire watershed, including water quality, fish habitat and water temperature, land use, and flood management.
