Mutual Aid Reimbursement System (MARS)

Introduction

The Mutual Aid Reimbursement System (MARS) is a web-based application that is managed by Cal OES and utilized by all fire agencies that respond under the California Fire and Rescue Mutual Aid System. The intent of this system is to reimburse local government ordered and requested through the California Fire Assistance Agreement (CFAA). The reimbursement process will be housed on one platform that is easily accessible to Cal OES, the paying entities, and the responding fire agencies.
