The Fall debris collection by the City will be happening on Saturday November 10th.  The city will pick up leaves bagged in paper bags and branches tied together in small bundles.  Since the trucks can be around early in the morning, you need to have your debris out on Friday night.  So start collecting your debris now to have it ready to put out after 7 pm Friday for pickup next Saturday morning.
