This is part of the problem with Socal no one really hunts them in that area. As for a County trapper some of the counties have done away with the position. You might check with Fish and Wildlife (no longer Fish and Game, that would imply we hunt). A shotgun with something other than 00 buck or slugs works well when in an Urban environment works well. The big issues are the neighbors all think coyotes are in a class with Rin Tin Tin, does anyone remember that, okay Lassie. That is until one takes fluffy off the front porch.
