Thus, a watersystem must have a supply, storage, and distribution system grid of sufficient capacity to supplyfire-fighting requirements while maintaining adequate service to residential and commercialcustomers.Fire-fighting guidelines have been established by the Insurance Services Office (ISO) andadopted by ordinance. Similar standards are administered in this state by the Washington Surveyand Rating Bureau (WSRB). Communities' fire suppression systems are reviewed and a publicprotection classification is developed for insurance rates. The public protection classificationnumber is on a relative scale from 1 through 10, with 10 representing less than the minimumrecognized protection. The city's current WSRB rating is 2.The most severe fire flows that are required to be met in several pressure zones within the Cityare listed in Table 4-7. The residential fire flow for the city varies from a minimum of less than1,000 gpm in some areas with older, small diameter pipe, to over 2,500 gpm. The city's firemarshal requires that the fire flow duration equal 1 hour for every 1,000 gpm of flow, with aminimum duration of 2 hours. Fire flows not evenly divisible by 1,000 gpm and greater than500 gpm are rounded to the next lower increment evenly divisible by 1,000. For example,2,900-gpm fire flow would require a 2-hour duration.Analysis of the city's long term fire flow availability in previous water comprehensive plansdetermined that 6,000 gpm at 6 hours duration was generally available in the highest risk areas,such as the CBD and some other commercial areas, while maintaining a positive residual4-14
