Queen Anne's County in Maryland uses pervious concrete to protect Chesapeake Bay by preventing rainwater runoff

“Urban and suburban runoff is one of the top contributors to the Chesapeake Bay's nitrogen load, and is also the fastest-growing nutrient pollutant source in the bay,” writes Aleksandra Robinson in an article published on Annapolis Hometown.

The focus of the artticle is on pervious concrete, which along with other stormwater/rainwater runoff prevention measures, is becoming more important in Maryland in light of the Stormwater Management Act of 2007. The key feature of the law is that it requires Environmental Site Design, known by the acronym ESD.

“By the end of 2009, Queen Anne's Bloomfield Farm — once a working farm that now encompasses a 19th-century homestead along with soccer, baseball and lacrosse fields, a fishing pond and a driving range — will sport 30,720-square-feet of pervious cement, along with 16,000-square-feet of permeable pavers.”
