Therefore, potential exposure and loss estimates <br />are approximate and should be used only to understand relative risk. Over the long term, the planning partners <br />will collect additional data to assist in estimating potential losses associated with other hazards. <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />7-8
