Environmental Tip #55 explains that grass channels (swales) reduce stormwater runoff and do a better job of encouraging infiltration and removing pollutants than traditional curb-and-gutter systems. It notes swales are usually shallow enough to be mowed as part of normal yard maintenance, are common in residential areas on Maryland’s Eastern Shore, and that homeowners are responsible for keeping them clear of debris; the tip closes by reminding readers every property needs stormwater management and that land actions affect the Corsica River and the Chesapeake Bay (www.corsicariver.com).

ENVIRONMENTAL TIP #55
DID YOU KNOW grass channels or swales reduce runoff and do a
better job of encouraging infiltration and removing pollutants from
stormwater than a traditional curb and gutter system?
Grass channels in yards are usually shallow enough that they can be
mowed as part of your normal yard maintenance.
On the Eastern Shore of Maryland, grass channels are common in
residential areas because they function well in relatively flat coastal
plain geography. It is the responsibility of homeowners to to
maintain grass channels by keeping them clear of debris and
blockages.
Every property needs some form of stormwater management to
prevent erosion and promote infiltration and remove pollutants
from runoff.
