conditions. In addition, the team determined the overall format of the adopted plan, including `The Planning Process' section, was dif�cult to follow and should be re-worked for ease of use and to be more consistent with the most recent adopted State Hazard Mitigation Plan Update from October 2007. Risk Assessment: As the adopted plan included the best available data from 2004, the OCHM Team determined that the data outlined in the Risk Assessment should be updated to reflect the best data available currently. The OCHM Team reviewed the adopted State Hazard Mitigation Plan Update(2007), as well as data provided by the National Weather Service,NOAA,and the State of North Carolina for more up to date information on severe weather occurrences and natural disasters affecting the United States, as well as the plan area. The majority of the revisions determined necessary by the team reflect the most current data available. In addition, the OCHM Team evaluated the hazards described within the Risk Assessment section of the plan. While several of the hazards discussed are unlikely to affect Orange County and the municipalities party to the Hazard Mitigation Plan (i.e. volcanoes;earthquakes, tsunamis), the team determined the description of the hazards included in the original adopted plan should remain in the update. The hazards described in the adopted plan were specifically required to be included in the original document by previous authorities and elected officials. While they remain in the update, additional analysis of those hazards was deemed unnecessary. Also, based on comments received, the OCHM team elected to revise the likelihood of Tornadoes potentially impacting Orange County and the Towns of Carrboro and Hillsborough, from "Unlikely" to "Possible". In addition, earthquakes were determined to be"Unlikely", versus"Possible". Finally,the OCHM Team determined the property information and values included in the ado ted lan wer � P P e also outdated. The Risk Assessment was revised to reflect the most current property value data for - Unincorporated Orange County,the Town of Carrboro and the Town of Hillsborough. Miti�ation Strategy: The OCHM Team reviewed the mitigation strategies and Action Items included in the original Orange County Hazard Mitigation Plan. After much discussion, the team determined the mitigation strategies for the hazard designated as "Moderate" and "High"remained valid. Minor revisions were made to the text but the strategies remained the same. The Team also determined further analysis and strategies were not necessary for the hazards identified as "Low" in the plan update. In addition, each jurisdiction updated their Capability Analyses shown in Appendices B, C and D to reflect the most current regulations and programs in place for each participating jurisdiction. Plan Maintenance: The OCHM Team discussed the Plan Maintenance procedures included in the approved Orange County Hazard Mitigation Plan and determined the overall processes were still appropriate. Minor changes to the text were made to make the language more current. The plans, studies and technical data sources reviewed by the OCHM Team and incorporated in the plan update are listed below. These sources are noted throughout the plan update. • National Oceanic and Atmospheric Administration (NOAA) -Top 20 States for Number of Tornadoes,Fatalities, and Damages, 1950 to 2007 • National Transportation Safety Board—Accident Database&Synopses 4
