Runoff from driveway can be reduced by routing roof water to flat, grassy area of yard or a garden spot

Please click on image to ENLARGE night view of rapid runoff from a paved driveway.

Most dwellings don't have a large prairie parcel to which stormwater runoff can be directed. However, simply routing roof water through gutters to the lowest, flattest part of the yard can reduce downstream flooding. If every building in the city is designed with this in mind (and if the natural soil and vegetation is left in place to provide a natural raingarden) an extremely large portion of runoff to our streams can be prevented.
