You may still be in a regulated area, even if outside the flood plain. Watercourses and the associated regulated flood plain are one of the natural features and hazards that are components of TRCA’s regulation limit. There are thousands of flood-vulnerable structures located in the flood plains within TRCA’s jurisdiction, either because they pre-date flood plain management planning policies and regulations, or because they were permitted under special policy and planning provisions. In locations where the flood plain remains undeveloped, the risk to life and property is reduced. This knowledge helps guide sensitive land use away from high-risk areas, and, for areas where historical development has already occurred, helps to identify ways to mitigate flood risk, all with the aim of better protecting people, property, and the resilience of our urban areas. Knowing the extent of the flood plain is an important tool for land use planning and emergency management. This objective is achieved through policies that limit development within the flood plain. Introduction Flood plain management is a fundamental objective of Toronto and Region Conservation Authority (TRCA).
