Sustainable Stormwater Retention Policy _Quebec



City of Quebec

Environmental and sustainable benefits

  • Protection of natural habitats
  • Sustainable stormwater management
  • Creation of ecosystems and green corridors
  • Increased biodiversity
  • Increased biomass
  • Heat island mitigation
  • Sustainable materials
  • Health and well-being
  • Lower infrastructure costs
  • Lower maintenance costs

In an optimal vision, the retention basin will become wetland ecosystems that filtrate stormwater prior to their return in nature.

We worked with the City of Quebec in the elaboration of a design, planning and management policy of existing and future retention basins. This policy will bring uniformity to the realisation of basins and guide the designers, consultants and developers with the instauration of practice standard practices.

This design and planning policy will affect more than 400 existing and future basins throughout Quebec City’s territory.

  • Concertation table with the municipal services
  • Exhaustive documentary research
  • Guidelines and innovative organisational concepts
