<br />Marian Meadows Rezone and Subdivision Final Environmental Impact Statement 3-146 <br />This typology is also reflected in the Insurance Service Organization (ISO) Public Protection <br />Classification (PPC) of fire protection in communities, which is based on the ISO’s Fire Suppression <br />Rating Schedule (FSRS), which includes the following criteria: <br />Receiving and handling of fire alarms <br /> Receipt, <br /> Operators, and <br /> Alarm dispatch circuits. <br />Fire department <br /> Equipment, <br /> Distribution of companies within specified response distances, <br /> Company personnel available for first alarms, and <br /> Training. <br />Water supply <br /> Adequacy of water supply in terms of: <br />o Hydrant’s size, type, and installation; and <br />o Hydrant’s inspection and condition. <br />3 What risks are posed by wildfire in the area and to the proposal and alternatives? <br />Wildland fires are fires caused by nature or humans that result in the uncontrolled spread of destruction of <br />forests, brush, field crops, grasslands, and real and personal property. <br />The wildland fire season in Eastern Washington usually begins in late May or early June and typically <br />culminates in late September with a precipitation event; however, wildland fires have occurred in every <br />month of the year. Drought, snow pack, and local weather conditions can expand the length of the fire <br />season. The early and late shoulders of the fire season usually are associated with human-caused fires. <br />Lightning generally is the cause of most fires in July, August, and early September. <br />People start most wildland fires on state land and private lands in Washington State. Major causes <br />include arson, recreational fires that get out of control, smokers’ carelessness, debris burning, fireworks, <br />and children playing with fire. The major cause of fires on federally protected lands is lightning (DNR <br />2009). <br />Factors that Influence Wildland Fire <br />A fire needs three elements in the right combination to start and grow – a heat source, fuel, and oxygen. <br />How a fire behaves primarily depends on the characteristics of available fuel, weather conditions, and <br />terrain.
