Benefits

There are many benefits of Naturalized Stormwater Retention Basin's:

  • Treat water quality
  • Lower construction and long term management costs
  • Mitigate invasive species
  • Use science to guide management decisions (adaptive management)

 

Things to consider

Naturalized Stormwater Retention Basin's do have some things to consider:

  • Require collaboration between biologists, engineers, planners, developers and municipal/provincial regulators during the design stage
  • Challenge the status quo of conventional stormwater ponds
  • Each site is unique based on soil composition, topography, and existing drainage patterns
  • Science based approach requires attention to detail and site constraints

 

Implementation

  • Establish clear guidelines for naturalization that developers and consultants can follow and understand the importance of plant species ecology, wetland biology, and SRB design requirements
  • Collaborate with the development team when reviewing potential sites
  • Choose site appropriate native plant materials
  • Pre-plan with the right length of time for site commissioning
