Tactic
Adaptation
Limit Exposure to Flash Floods
Reduce excess water
Options
...by exiting water off site as quickly as possible without burdening the storm sewer system (exiting the clean surface water of a park to a water body, etc.).
...by amending soil to increase its infiltration capacity.
...by exiting water via infiltration to avoid the storm sewer (stormwater wetlands, permeable pavement).
Case Study
As part of an effort to reduce the volume of polluted stormwater runoff entering nearby water bodies, Weber Thompson designed the Aurora Bridge Swales, a series of bio-retention cells that redirect, slow, and filter storm water from the north span of an overhead vehicular bridge.
