Don't "P" down the (storm) drain

Please keep your leaves and grass clippings out of the streets; they add P (= Phosphorus) to our ponds, creeks, and the Mississippi River when they get washed down stormdrains. They do not get cleaned at a water treatment plant!

Plus, the stormdrains can easily get clogged!

So, keep your "P" to yourself (or at least your lawn; besides, it can use it!)
