So these arbitrary laws that starve lawns and cause them to thin out don't do much good. I can see prohibiting the dumping of grass clippings down storm drains. I can also see doing whatever it takes to hold soil in place, including growing a vigorous stand of turf. Can't do that when a non agronomist or non horticulturist is writing fertilizer restrictions. I even see water restrictions as counterproductive because when the grass is killed by lack of water and it finally storms, what happens? Don't want pollution, you would have to concrete every square inch of land and send all run off water into a treatment facility.
