Mutual Aid Reimbursement System (MARS)


The Mutual Aid Reimbursement System (MARS) is a web based application that will be managed by Cal OES and utilized by all fire agencies that respond under the California Mutual Aid System. The intent of this program is to make reimbursement under the California Fire Assistance Agreement (CFAA), housed under one platform that is easily accessible to Cal OES, the paying entities, and the responding fire agencies.
