Equipping Albertans to create vibrant, ecologically functional landscapes within the built environment, through comprehensive stormwater management.


We need houses and roads for our growing population. Unfortunately, all those hard surfaces result in twenty or more times the runoff than a natural landscape! And that runoff can be quite dirty.

Low impact development is an evolution of the science of stormwater management. It is an approach that mimics nature's features and processes in order to minimize and clean up this runoff in the most economical way possible--while maximizing environmental and social benefits.
