Duplication of benefits refers to assistance from more than one source that is used for the same activity. In this instance, a duplication of benefits would occur if a property is cleared by CalOES and the property owner was paid by their insurance company for the removal of that debris (the same activity) and retained the funds. A duplication of benefits would not occur if CalOES cleared a property and the owner received insurance proceeds for that activity and remitted those proceeds to CalOES.
