| Emergency Planning - Risks Page Welcome:- A) A Risk assessment Tool B) An example of its use A Risk assessment Tool Summary of the six step local risk assessment process 1 Contextualisation • Review or describe social, economic, received cultural, infrastructural and environmental issues within local context 2 Hazard review Local assessment What is the Resilience of your own unit and knowledge of local initiatives and resources. What agencies are involved? What plans do they have for your area? Level involved Are there any hindrances to these plans operating? 3 Risk analysis Likelihood of hazards’ • Local Risk Assessment Guidance
4 Risk evaluation The Risk impact upon your local agency plant if it happened. 5 Risk treatment • Set risk priorities • Evaluate proposed options for additional treatment of risks and agree risk treatment plan • Identify officer or organisation to be responsible for implementation of actions • Actions communicated to appropriate working groups 6 Monitoring and review Are the risks still there; getting better or worse? Are the reilience plans still in place and appropriate?

4C.1 Overview of hazard or threat Flooding: • Most commonly caused by intense bursts of rain causing flash floods or prolonged rainfall on saturated ground in river catchments, which result in rivers or other watercourses overflowing their banks. • May lead to a minor inundation of properties and road closures, or result in widespread loss of life and devastation of property necessitating the implementation of a co-ordinated recovery plan. 4C.2 Key historical evidence 2000 October/November – United Kingdom – prolonged severe rainfall led to the flooding of 12,000 homes nationwide. The River Ouse at York flooded hundreds of properties with estimated £400 million damages. The Aire flooded over 300 properties in Selby and Barlby and 300 at Stockbridge near Keighley. 1999 March – North Yorkshire – River Derwent burst its banks and inundated Malton and Norton forcing 200 families to abandon their homes (recurred in November 2000). 1998 April – Midlands – extensive flooding killed 5 and damaged 4,500 homes in Northamptonshire, Warwickshire and Oxfordshire. 4C.3 Likelihood Igleby appears to be experiencing more instances of all forms of flooding in recent times, in particular as building continues in several floodplains. Hazard/threat category: Sub-category: Severe weather Flooding (main river) Hazard and threat description, including scale: Risk reference no. River W – 10 square miles and 50 square miles SW1 Date of revision: Next review date: July 2004 September 2004 Hazard Outcome description Likelihood Flooding (main river) 10 square miles Probable (5) Flooding (main river) 50 square miles Negligible (1) 4C.4 Impact Summary Details 4C.5 Vulnerability and resilience Areas across Igleby with a high potential for flooding based on topography and historical incidents include Hotton, Nimby and Coneywood Bridge. 4C.6 Overall assessment Hazard Outcome description Impact Flooding (main river) 10 square miles Significant (4) Flooding (main river) 50 square miles Catastrophic (5) Impacts associated with floods: Primary: Drowning of people, pets and livestock Major damage to property and surrounding land Closure, or washing away, of roads, bridges, railway lines Loss of (and possible damage to) telephone, electricity, gas and water supplies Pollution/health risks from sewerage systems, chemical stores, fuel storage tanks Evacuation and temporary/long-term accommodation needs Secondary: Need for recovery strategy in aftermath of major flood Disruption of economic life and major costs of rebuilding infrastructure Public need for information, advice, benefits/emergency payments Insurance implications, including help for the uninsured Safety assessments/possible demolition of damaged buildings and structures Shortage/overstretch of key resources (equipment and personnel) and agencies Overstretch of normal communication links, including mobile phones Category: Sub-category: Severe weather Flooding (main river) Outcome description Impact Likelihood Risk 10 square miles Significant Probable VERY HIGH 50 square miles Catastrophic Negligible MEDIUM Controls in place: Council: Major Emergency Plan; Generic Flooding Plan; Major Flood Incident Plan for River Aire.Other organisations: • Environment Agency, ‘Local Flood Warning Plan for Igleby Area’. • Police: Flood Warning and Flood Response; Flood Plan for River Wandle. Additional risk treatment required: • Assist Environment Agency in take-up of automated voice messaging for use in warning local residents and encourage better flood preparedness in communities. • Work with Land Drainage on the mapping and identification of ‘flooding hotspots’ on becks and other watercourses. 194 ANNEX 4C: EXAMPLE OF AN INDIVIDUAL RISK ASSESSMENT
