O & M Survey Questions Background Funding Dedicated Personnel Practices & Ownership At what point is scale reached (# of practices needed where cost becomes affordable*) Funding Where does it originate How much is allocated to Inspection, Maintenance and/or Both Dedicated Personnel Municipality Contractor Volunteers Other / Combination Inspection & Maintenance Responsibilities Forms Maintenance Agreements
