The spring floods of 2017 affected a vast area within Québec.
The frequency and intensity of similar events will be affected
by climate change. The management of flood-risk areas shall be
adaptive thanks to notably real time data, future climate
mapping or regarding land development purposes.
has many floodplain models and maps for various rivers within
its boundaries, and uses the Protection Policy for Lakeshores,
Riverbanks, Littoral Zones and Floodplains. However, the spring 2017
floods cast light on the need to rethink the scope of the
available tools, as well as consider future needs and the
possibility of reviewing the floodplain management policy.
The aim of this Plenary Session was to look at the level of
efficiency of our ways of doing things and current Québec
measures, with a view to ensuring that management and oversight
can evolve, adapt and apply to all flood-risk areas.

Protection Policy for Lakeshores, Riverbanks,
Littoral Zones and Floodplains
The goal of this policy, adopted in 1987, is to grant appropriate minimal protection to the
ecological and biological components of all
lakes and rivers and to ensure the security of
individuals and property in floodplains.

This guidebook reviews and explains each of the
Policy’s provisions. It is both a document
