Bioinfiltration strategies on streets and parking lots, such as vegetated filter strips and grass swales,  are alternatives to typical curb and gutter design that allow for infiltration of stormwater, as opposed to conveying the runoff to storm drain

Reducing the number of curbs, storm drains, and piping systems can substantially reduce construction costs.
