I was preparing my talks for the upcoming LID Conference in Philadelphia and EPA Watersmart Conference in Las Vegas, when I stumbled across this great calculator for quickly comparing costs and benefits of various stormwater BMPs. The National Green Values™ Calculator is the brainchild of think-and-do tank, Center for Neighborhood Technology in Chicago, IL. Check out the calculator and the great, community-based work of CNT. Great minds DO think alike!
