Cities of Dublin and Pleasanton | Disaster Debris Management Plan | 2022 <br />5 <br /> <br />expeditiously recovering from a debris-generating event, the DDMP will outline pre-event <br />preparations during times of normalcy, operations immediately prior to a known disaster threat, <br />operations following the disaster event, and demobilization and close-out following completion of <br />debris removal efforts. <br /> <br />Table 2 describes potential debris-generating disaster incidents that may affect the Cities. The table <br />also estimates the probability of the disaster event, the nature of debris generated, debris generation <br />potential, and the widespread impact throughout the Cities. Probability, Severity, and Risk Ratings <br />are derived from the 2018 Tri-Valley Local Hazard Mitigation Plan. <br /> <br />Table 2: Potential Disaster Incidents and Debris Types <br /> <br />Type of Event <br />Probability <br />of Event <br />0.0 to 1.0 <br />Severity of <br />Event <br />1 to 10 <br />Risk Rating <br />(Probability x <br />Severity) <br /> <br />Nature of Debris <br />Debris <br />Generation <br />Potential <br />Widespread <br />Impact <br />Earthquake .5 10 5 <br />Construction and <br />Demolition (C&D,) <br />Household <br />Hazardous Waste <br />(HHW ), <br />White Goods such <br />as major household <br />appliances, Soil, <br />Mud, Sand, <br />Household Items, <br />Electronic Waste <br />High High <br />Flood 1.0 5 5 <br />C&D, Hazardous <br />Waste, <br />HHW , <br />White Goods, Soil, <br />Mud, Sand, <br />Vehicles, Household <br />Items <br />Moderate Moderate <br />Wildfires 1.0 5 5 <br />Vegetative, HHW , <br />White Goods, <br />Vehicles, <br />Soil, Mud, Rock from <br />Mud Flows, <br />Household Items, <br />Electronic Waste <br />Moderate Moderate <br />Landslides .5 5 2.5 Soil, Mud, Rock from <br />Mud Flows Low Low
