In an effort to curb urban flooding, the city of Madison is offering residents of one West Side neighborhood up to $1,000 to install rain gardens, porous pavement and other features designed to keep water out of storm sewers.
With such large rain events likely to become more frequent as the climate warms, the city council directed the engineering department to develop watershed models and plans for watersheds of greatest concern. The department was also asked to start a campaign to use green infrastructure to keep water out of the storm sewers, which are designed to move rainwater quickly into rivers and lakes.
