County officials believe the legislation addresses both the quantity of stormwater runoff that flows into rivers, streams and stormwater facilities, and the quality of the runoff. It requires developers to create filters and include natural landscaping in their plans. Ineffective stormwater management can lead to flooded homes, polluted rivers and eroded sewer pipes.
As required by a bill the Maryland General Assembly passed in 2007, 17 counties have adopted new stormwater management regulations. Six counties, including Prince George’s, have pending legislation. (Wash Post, 6/20/2011)
