Deering Woods Condominium Association

What is polluted runoff?

Parts of the Chesapeake Bay watershed contain a high percentage of impervious cover – paved or other hard surfaces such as roofs and roadways that prevent rain water from being absorbed into the ground.  Instead, water runs along these surfaces, collecting trash and substances such as motor oil, lawn fertilizers, and pesticides.  This polluted stormwater flows into streams and rivers, where it threatens aquatic ecosystems and public health.

Effective stormwater management, on the other hand, creates safe paths for polluted runoff to be captured and filtered through the ground before it reaches waterways.  This helps keep the environment clean and our communities healthy!

Project Location: Columbia, MD

Problem: Twenty-five townhomes in the Deering Woods Condominium Association of Howard County, Maryland, lacked a stormwater treatment plan.  Rain events led to flooding and erosion problems. 

Solution: A 200 foot x 15 foot linear rain garden was installed throughout the community to alleviate drainage problems. The bioretention capability of the rain garden now absorbs 100% of the rain water runoff.  

The READY program offers an ongoing maintenance program which visits the site four to six times per year to ensure the success of the stormwater features installed. 

Cost: $9,700
