Municipal compost is loaded with seeds from everything imaginable. There is no way to kill them other than steam or heat sterilizing which is what the commercial products get. Municipal or home grown compost is good for gardens maybe where you can pull weeds all summer but most people who use it on their lawns find out the hard way you don't want to do that. I have a neighbor who had a couple of yards delivered for his garden. They dumped it on his lawn next to the road in the front of his property. Now that area is solid nutsedge and spreading.
