Do you know it was left out by a particular person from a specific house? If so, it should be reported as illegal dumping to LCI, the homeowner, the police dept. or public works. If not, it is not fair to assume that the scattered site housing has anything to do with the problem. If the scattered site housing is all owned by a particular landlord, any problems that occur can be addressed to them or as previously stated any of the above depts.
