“The region has committed to protect and restore an interconnected network of habitat and green space, account for ecosystem services, and enhance the connection between people and nature. Over time, the outcome of a landscape-based approach is a new watershed,” stated Kim Stephens.
“Metro Vancouver will continue to work with the member municipalities to complete the remaining actions. Vancouver and Burnaby are implementing the actions that are specific to each municipality and continue to collaborate with Metro Vancouver on the joint action items,” stated Ed von Euw.
Studies in Salt Lake County, Utah, help determine whether first flush exists in the region and the implications for choosing stormwater treatment systems.
More rational decisions on treatment system selection and design would occur if stormwater engineers adopted a concept long established in other branches of engineering: unit processes and unit operations

The distinction between the “engineered filter” and “nature’s filter” has blurred. The underdrain system is soil rather than pipes. The filter media is the native soil. But it is becoming more common to specify engineered media.
Local government action and support are resulting in a continuous increase of the number of LID projects which mimic natural rainwater processes such as infiltration.
Stormwater Management: Using trees and structural soils – manual cover (360p)
Researchers know that urban forests, like rural forest land, can play a pivotal role in rainwater/stormwater mitigation. Structural soil reservoirs may provide new opportunities for meeting engineering, environmental, and greenspace management needs in urban areas.

The workshop provided an overview of what homeowners can do to manage rainwater on their property.

Solutions to climate change often originate from small scale community initiatives. This project is an excellent example of local scale action that can provide valuable information. Green roofs have an immense potential for offsetting carbon emissions originating from building operations.
A recently completed rainwater/stormwater management system will remove up to 85% of the stormwater pollutants released into Little Bridge Creek.
