ISO collects and evaluates information from communities. This data is then analyzed using the Fire Suppression Rating Schedule and a Public Protection Classification (PPC) number is assigned to the community. Valdez currently has a PPC rating of 4, with the new fire station project, Valdez should be able to move up to a class rating of 3. The higher the class rating the lower the fire premiums for homeowners and commercial fire insurance. Insurance companies who determine rates for fire insurance use the ISO Public Protection Classification system. Not all insurance companies use the PPC, but majority do.
