Green Roofs Can Reduce Stormwater Runoff, Reduce Stormwater Fees!
By: Rebecca Gullott
Not many Marylanders are happy about paying the new stormwater fee or “rain tax” as it has come to be known. The county imposed fee is based on the amount of impervious surface such as rooftops and driveways on each property (cost-by-cause principle). In Howard County alone there are over 19,000 acres of impervious surfaces that contribute to pollution of local streams and the Chesapeake Bay. 19,000 acres are almost 30 sq miles or 11% of the counties size- more than double the size of all water ways in the county! No wonder that Stormwater runoff is responsible for over 20% of pollution into the bay.
Those wishing to lessen their stormwater fee can reduce the impervious surface area on their property through smart design and management practices. Howard County is providing instruction and incentives for citizens to do just that. Howard County Stormwater Management Division has partnered with several organizations including the University of Maryland Extension to help citizens take control of their environmental impact. Rainscaping workshops will be offered this summer to show residents how to plant and maintain rain gardens and native species; as well as compost waste and use rain barrels to collect roof runoff for use in lawn and garden irrigation or car washing. Howard County is offering free rain barrels at the Alpha Ridge Landfill select Saturdays April through September. Other Maryland Counties have similar programs so check your county’s website to see what offerings are available.
Property owners can receive credits for on-site improvements that reduce impervious surfaces. Whether it’s establishing a rain garden in the yard or incorporating planted areas or green roofs into the company’s parking lot, these incentives may encourage citizens to take control of their environmental impacts. These changes may help to reduce the need for future stormwater fee increases and promote a healthier Chesapeake for years to come.
The possitive impact for the environment by implementing cost-by-cause fess is very effective in many other counties and States in the US and over decades in Europe.
