Stormwater planters
Over subsurface infrastructure, soils prone to subsidence, or pollution hotspots, it may be necessary to prevent all infiltration. These BMPs can also be squeezed into tight urban spaces, adjacent to buildings and within the usual setbacks required for infiltrating facilities. Stormwater planters can also be used as a means of providing building-integrated LID by capturing a portion of the rainwater from the rooftop.
Overview[edit]
Stormwater planters are an ideal technology for:
- Sites which cannot infiltrate water owing to contaminated soils or shallow bedrock,
- Zero-lot-line developments such as condos or dense urban infill.
The fundamental components of a stormwater planter are:
- a planting bed of storage media,
- suitable vegetation,
- decorative aggregate or stone,
- An underdrain
The design may benefit from:

Proprietary links[edit]
A number of precast modules exist to contain treatment media. As many of these systems are enclosed water balance calculations may be erroneous where evapotranspiration is constrained.
In our effort to make this guide as functional as possible, we have decided to include proprietary systems and links to manufacturers websites.
Inclusion of such links does not constitute endorsement by the Sustainable Technologies Evaluation Program.
