We often ask ourselves how we can make a difference in the health of our environment at home. One of the answers is to build a rain garden. There are now well over 1,000 rain gardens in Washtenaw County as the Water Resources Commissioner's Office has scaled a decentralized network to capture and filter stormwater. It's making a difference, and the effort will expand this year. WEMU's David Fair gets more details in a conversation with Rain Garden Coordinator, Susan Bryan.
