Improperly Installed Fences May Cause Drainage Problems and Flooding!

Every time it rains, many homeowners experience drainage issues on their properties. Some of these drainage complaints result from improperly installed fences. An improperly installed fence can block storm flows — runoff from storm precipitation — and cause water to pond in your yard or your neighbor’s yard. Blocked water can damage fences, draw mosquitoes and hasten lawn erosion.

Fences must be installed with storm flows in mind to ensure fences don’t block stormwater flows!
