Why is it important to manage stormwater properly?
Effective stormwater management reduces the amount of runoff and runoff pollution by slowing runoff and allow- ing it to soak in . When stormwater stays close to where it falls, less soil erosion occurs and fewer pollutants are car- ried to surface water.
