· A network of new wetlands and basins in the Avon River red zone lands
· To intercept and purify stormwater before it is discharged to the rivers or ground, and
· To detain and divert flood waters to avoid flooding of neighbouring residential areas.
Considerations:
· Wetlands are the kidneys of the city, filtering out sediments and contaminants before water is discharged to rivers or soaks into the ground.
· Wetlands and detention basins can receive large volumes of flood waters and help prevent the overloading of drainage systems during high rainfall events, storm surges, etc.
· Wetlands should be located where stormwater pipes currently run to outlets into the rivers so they can intercept the flows.
· Almost all of the Avon River Red Zone lands are located within the CCC Flood Management Area.
· Allowing land to return to wetland does not increase the existing risk of liquefaction or create any new risk of liquefaction, of adjoining lands.
