Rain gardens can be an effective way to divert clean rainwater back into the ground water system instead of being wash over driveways, streets and sewers collecting contaminants from pets, lawn chemicals and road pollutants. Lynn sent me the following note and pictures. "I thought you might like to see the rain garden the Rockaway Valley Garden Club built last week. The water runs off the road into this area and all the plants are natives . It is located next to the grammar school on Valley Road in Boonton Twp. (take Powerville Road to Valley Road)."
