Which of the following best describes the institution’s approach to rainwater management?:
Comprehensive policies, plans or guidelines that require LID practices for all new projects

A brief description of the institution’s green infrastructure and LID practices:

Université Laval covers a surface area of 1.9 km2 in Québec City. The storm sewers feed into the city’s own system. Stormwater volume is restricted to prevent overloading the municipal infrastructure.

In 2011 Université Laval undertook a large-scale program to upgrade its sewer system. A cleaning and diagnosis program made it possible to update plans and model the various systems. In recent years deficiencies have been found in the sewer systems, particularly for stormwater during heavy rain. A master plan was drawn up and submitted in 2013. Stormwater retention solutions were developed to limit runoff and prevent overflow. In addition, all new surfaces (roofs, parking areas, streets, etc.) are assessed for their impact on overall water runoff on campus. To control runoff, stormwater retention basins have been built.

It should be noted that when roads and parking areas are rebuilt, impermeable surfaces are minimized to promote the natural seepage of water into the ground and thus prevent additional loads on the existing systems. Whenever possible retention at source is encouraged for these new structures.
