ISO RATINGS

Effective January 1st 2019, our NEWEST ISO Class 5/5Y Rating took effect for all subscribing homeowners *Class 5: Homeowners within 5 road miles and within 1000 feet of an approved Fire Hydrant, and the 5Y Rating: Homes within 5 road miles of the fire station but NOT near an approved Fire Hydrant.

Anyone beyond five miles, according to the ISO is a Class 10. The Insurance Service Office limited ANY serving fire station to a FIVE Road Mile Range from its station and does not rate fire protection for any station nationwide if they serve areas greater than 5 miles, unless a Satellite fire station is established to offer coverage to those more distant areas in the District.

This Fire Protection Rating is Proprietary. This means that only pre-paid fire protection subscribers who financially support the fire department are eligible for the ISO protection classification of the Class 5 or 5Y where eligible.

Regional Fire & Rescue Department, Inc., is the public service fire protection provider for Unincorporated Central, and portions of Western Pinal County, and was evaluated and rated by the Insurance Service Office initially in the Spring of 1996, following one year of service to this area. A re-rating took effect in September 2012 and a corrected rating received in November 2013. RFRD had been previously issued a split rating of a Dwelling Class-8b and Rural Class-9 (since May 1, 1997) for homes and businesses in our response area within 5 road miles distance from our station. RFRD now enjoys a NEW and IMPROVED ISO Rating of a Class 5 & 5Y for our subscribing residents and businesses within 5 road miles of our station.

Since 2003, the ISO has reduced the application of this ISO Rating System to apply to those homes or businesses only within a 5 mile radius. This unfortunately, adversely affects home and business owners greater than five miles or as many as 10 to 15 miles where the Rural Class-9 Rating once applied. This is no longer the case. We are planning to expand to a second station for the Hopi Hills area that would provide lowered ISO ratings for residents north of Casa Grande. However we are still awaiting a land donation to come through in order to apply to the USDA for funding to construct and new fire station with two bay truck bay to house an Engine and a Water Tanker (Tender) in what will be labeled “Station 587”. Unfortunately our biggest challenge is securing land to build the proposed fire station.

Availability of this lowered ISO Rating and system can only be achieved by moving additional apparatus to the Hopi Hills Community. We require property to be able to house this apparatus, and potentially provide "live-in" Firefighters to provide cost-neutral manpower in the event an emergency occurs that can provide them the opportunity to respond. The ISO has now forced this situation and we feel the urgency is at hand to establish additional locations which can house apparatus, yet no manpower or staffing requirement would exist to achieve the Class 5/5Y rating to improve homeowners insurance rates as well as economic factors for the community.

In our history, some insurers or their underwriters previously accepted the Rural Class-9 Rating from five, to as much as 10 or even 15 miles from our fire station, however this no longer the case as the 8b rating is only applicable to within a Five Mile radius of the serving fire station. By utilizing Google Maps online, you can obtain road mileage to your home from our fire station using our physical address (7951 W. McCartney Road) to determine road mileage. This situation will not improve until or unless we can obtain community assistance in locating and establishing a suitable permanent site (or lot) of which may have a single wide mobile home or building that could be remodeled for living quarters, and would have the space available to construct a metal enclosed building to store fire trucks securely.

“Proprietary” ISO Rating:

The Eligible ISO PPC™ Rating is only authorized for businesses or residents who “pre-pay” a fire protection Subscription (Annual Dues) to the fire department to establish a fire protection service agreement. Those who do not subscribe for service can be billed Hourly as much as $750.00 per hour, per Apparatus, and $75.00 per hour, per Firefighter costing a homeowner thousands for fire suppression fees if they suffer a fire or similar emergency before becoming a pre-paid fire service subscriber. A resident or business owner who does not pre-pay and establish a subscription is subject to the hourly fees, however there exists no obligation to respond to your location if you are not a current subscriber of our service.

Arizona Department of Insurance (ADOI):

It is critical that all Insurance Agents and Brokers follow established regulations pertaining to eligible ISO Rates as required by the administrative rules under the Arizona Dept. of Insurance (ADOI) and follow those regulations highlighted by Circular Letter 14-07 (click on circular letter below) with regard to the lawful application of ISO PPC Ratings for fire jurisdictions when establishing an insurance policy for a resident or business owner location in our community. A $500 fine can be levied to an insurer or agent in misrepresenting or improperly or intentionally writing a policy under the wrong ISO classification. If the client does not have a “pre-paid” fire protection agreement or “subscription” in place they are deemed an ISO PPC-10 (Having NO fire protection). Once the insured establishes fire protection, he is authorized the ISO Rating being utilized by the insurance company in writing the policy, but not before.

CIRCULAR LETTER NO. 14-07

From the ISO Web Site:

The ISO PPC™ program provides important, up-to-date information about municipal fire-protection services throughout the country. ISO’s expert staff collects information about the quality of public fire protection in more than 44,000 fire districts across the United States. In each of those fire districts, ISO analyzes the relevant data and assigns a Public Protection Classification — a number from 1 to 10. Class 1 generally represents superior property fire protection, and Class 10 indicates that the area's fire-suppression program does not meet ISO’s minimum criteria.
Virtually all U.S. insurers of homes and business property use ISO’s Public Protection Classifications in calculating premiums. In general, the price of insurance in a community with a good PPC is substantially lower than in a community with a poor PPC, assuming all other factors are equal.

A community’s PPC depends on:

• fire alarm and communication systems, including telephone systems, telephone lines, staffing, and dispatching systems.
• the fire department, including equipment, staffing, training, and geographic distribution of fire companies.
• the water-supply system, including the condition and maintenance of hydrants, and a careful evaluation of the amount of available water compared with the amount needed to suppress fires.

Closest Fire Hydrant:

Regional Fire began service to the area on April 8th 1995 without any fire hydrants in our service area of the County. Since that time, we now have over 280 Fire Hydrants, however they are generally located in the newer housing development tracts and not generally located within previously established residential neighborhoods. You can contact the fire station to obtain fire hydrant information which is specific to your business or residence address. Our ISO PPC 5Y Rating is based on water carrying capability for response with at least 4000 gallons on the initial response to a reported Structure Fire within 5 road miles of our fire station. As you can see form two of our four apparatus listed above, we can provide 5,000 gallons on the initial response.

Fire Station Staffing:

Regional Fire’s station is manned 24 hours per day, 365 Days per year by a minimum of Two Fire personnel and occasionally have additional staff of 3-4. Full-time personnel include Certified Firefighter/EMT’s and Paramedics per shift and the Fire Chief/Paramedic who is on call after normal work days (M-Sat).


Certified Reserve Firefighters support and assist the full-time Staff Firefighters for additional personnel when needed, provide additional personnel for fire responses and routine shift-fill opportunities monthly. These Reserve Firefighters are Paid-Per-Call, or Hourly (part-time) employees who are Certified as Firefighters, EMTs and Paramedics.

Our average response time is currently 12 minutes. Due to the rural makeup of the response territory we provide service to, with vast mileage consisting of open desert and farm fields dotted with the occasional housing or rural development enclaves, we must maintain a full-time workforce to maintain the quickest and most effective response to our residents in times of emergency. Serving residents from strictly a Volunteer firefighting force is not feasible due to the lack of a population density to support an all-volunteer workforce and expansive territory and resulting response times.

We currently serve 96 square miles and just under 100 miles of State Highway and Interstate from one fire station with response times upwards of 25 minutes in some cases (to the Pinal-Maricopa County Line on Interstate-8 for the Highway Patrol). If we only had volunteers, responding from 10-25 minutes away (to the station) to assist in emergencies would delay the first due response and result in 30+ minute response times. Therefore we must maintain a full-time/Paid Reserve dedicated workforce with what limited funding we receive, and available subscription dues being directed to support the fire department overhead expenses.
