Thank you for the opportunity to address the Standing Committee on Environment and Sustainable Development regarding the study on disaster mitigation and insurance.
First off, I would like to formally introduce myself. As mentioned in the introduction, I am Brad McNevin, chief administrative officer with Quinte Conservation. I've been employed in the environmental sector for the past 20 years, working with Fisheries and Oceans Canada, private environmental and engineering consulting firms, and currently with Quinte Conservation for the past 15 years.
Quinte Conservation is one of 36 conservation authorities across the province of Ontario, which is the only province to have these great organizations. Conservation authorities began to be established in the 1940s to address severe flooding and erosion problems. The most severe flooding on record in Ontario occurred in October 1954, when Hurricane Hazel passed through southern Ontario. Eighty-one people died and damages were estimated at $180 million. Following the devastating impact of Hurricane Hazel, a flood forecasting and warning system was established in the province of Ontario. Several flood control facilities were significantly upgraded and constructed. Operational practices were designed to respond immediately to changing conditions. Regulations were put into place to limit and control future development and inappropriate land use activities in flood hazard areas.
As I stand here today, many places throughout Ontario and other provinces have recently gone through significant flooding within the last month or so. In my own region, we are still experiencing Bay of Quinte and Lake Ontario surpassing their historic high-water level that was established a mere two years ago, in 2017. In contrast, the Quinte Conservation region experienced a significant drought in 2016. It impacted many user groups, not just rural residents, with dry wells. In fact, 100% of the Quinte Conservation region was impacted in some way. Drought conditions observed in our lakes and rivers impacted fish and wildlife. Our agricultural community experienced hardship trying to keep livestock and crops watered, which resulted in financial impacts. Homeowners were hit with costs associated with purchasing bulk water to keep their households running. Municipalities had to implement bylaws for restricting water use.
Extreme and unpredictable weather events are occurring frequently throughout the globe. There is no doubt that it is prevalent throughout our region and our watersheds. These extreme and unpredictable weather events can be related to disasters in the form of impacts on our forests, lakes, rivers, wetlands, fish and wildlife, and also, as many people have recently experienced, property destruction.
We can build resilience to a changing climate through proper planning and adaptation. Quinte Conservation developed a climate change strategy in 2016, recognizing the reality of extreme weather events related to flooding, drought and an increase in intense rainfall. Several action items have been developed with the aim of meeting our goal in helping our watershed residents both adapt to and mitigate the impacts of climate change. Natural infrastructure has a pivotal role in preventing and mitigating impacts of extreme weather events.
Collectively, conservation authorities own and protect 150,000 hectares of land, including forests, wetlands, areas of natural and scientific interest, recreational lands, natural heritage and cultural sites, as well as land for flood and erosion control. The forests, wetlands, moraines, grasslands and other natural features and ecosystems found throughout conservation authority lands help to prevent and reduce the harmful impacts of climate change. They protect and improve water quality, reduce flooding, act as drinking-water sources, increase biodiversity and provide healthy habitats for a wide range of wildlife, fish and birds. Conservation authorities play an important role in natural infrastructure protection, restoration and management in Ontario.
We see on a regular basis large-scale deforestation, which takes away the natural ability of water to be absorbed, retained and recharged slowly into the water budget. Protection measures are needed to help preserve forests. Forest cover allows for improved water quality, slows overland flow after extreme and intense rainfall, and in turn promotes infiltration into the groundwater. An increase in forest cover through such properly funded tree-planting programs as “50 million trees” is an important part of disaster mitigation. We have many partners, including municipalities and the private sector, and collectively plant close to 2.5 million trees per year. We partner with Ducks Unlimited Canada and alternative land use service programs to restore wetlands and other natural features.
There is a strong need to enhance and strengthen protection measures for all watercourses, wetlands and headwater drainage features. Wetlands provide benefits during drought and flood events. They store water, recharge ground water, allow sediments to deposit, and provide important habitat for fish and wildlife.
They help to slow water flow, improve water quality and sequester carbon. Urban watercourses in many areas consist of historically constructed concrete channels where water flow is restricted and is encouraged to flow as fast as possible. One step in flood mitigation can be addressed by allowing watercourses to use their natural flood plains, overflow their banks and slowly allow the water to move through the system.
Some areas that have already been urbanized will be difficult to mitigate. We need to encourage all levels of government to put a high priority on reviewing development applications so that development is in the right location. Flood plains and wetlands are not the place to allow development.
Conservation authorities support green infrastructure and low-impact development initiatives. We take a watershed management approach to planning and developing strategies for restoration and management. Disaster mitigation should include recovery programs where if homes are in flood plain areas, the government should require flood-proofing as a condition of funding. Where possible, rather than building on the same footprint, homes should be moved away from current and future predicted flood risks.
Programs should consider relocation funding rather than rebuilding. Investing in flood plain mapping and increasing the coverage of flood plain mapping will help with disaster mitigation and prevention. Some of the flood plain mapping equity conservation is from the 1970s. There have been significant changes in infrastructure and land use, and this impacts the accuracy of existing mapping.
In our region of Ontario, many watercourses do not have flood plain mapping. We require accurate and up-to-date flood plain mapping to guide in decision-making during development reviews.
Flood plain mapping needs to include flood scenarios to assist with emergency responses to public safety. For example, if a known area is susceptible to flooding and we have details regarding what flood levels occur at specific flow events, emergency responders will have the tools and information required to know where to direct resources.
We need to invest in more real-time models to better track specific events and see how storms will affect flood plains and the surrounding landscape, as well as invest in improvements to the existing precipitation, snow depth and flow monitoring networks. In a flood event, precipitation is typically the most unknown quantity and has the largest impact on flooding. Precipitation is the driver of flood events, so let's build a better network to monitor quantities.
Environment and Climate Change Canada is doing a good job with rating curves, which are basically the relationship between water height and flow. However, we need to continue to improve their accuracy and expand the monitoring network. Although dams and infrastructure are not necessarily natural, they play a very important role in disaster mitigation. Investing in flood control and water management structures provides value during extreme events by capturing run-off and controlling the release when appropriate to reduce the timing of peak flows.
They also are important in reducing the impacts of drought when properly operated. However, reservoirs at these structures are limited to specific capacities and cannot be expected to be the only answer.
Dams have substantial public safety and operational risks and liability. Many structures need significant investment to avoid potentially worse flooding and drought impacts. In the Quinte region alone, we have 42 water management structures that require significant investment for major, minor and preventative maintenance. As we explore options for these structures, consideration will be given to de-commissioning and refurbishing to a natural dam design to allow for less financial needs in the future.
In summary, we know that climate change is directly impacting our weather and our communities. There is no better time than the present to start taking the necessary precautions, preparing for these impacts and ensuring that our country is prepared for the future. We need to promote forest preservation, support tree planting programs, and enhance and strengthen protection of watercourses, wetlands and headwater drainage features. We need to ensure that development is located in the right place, not in flood plains and wetlands.
The natural environment has built-in mechanisms to mitigate extreme weather. We need to allow these features to function properly and allow intense rainfall to flow into the natural flood plains of lakes, rivers and wetlands. Urban stormwater management facilities can help, but protection of wetlands and flood plains is a better solution. We need to invest in enhanced and expanded flood plain mapping coverage, continue to invest in improved real-time models to track storm events and continue to invest in improvements to precipitation, snow depth and flow monitoring networks.
Canada needs to be a leader in addressing the impacts of severe weather events. This committee is tasked with an important focus that cannot be ignored.
