The UDO will implement the policies outlined in the Comprehensive Plan. <br /> Implementation of the types of policies likely to be included in the Comprehensive Plan <br /> update should reduce vulnerability to such hazards such as flooding, landslides, and <br /> wildfires. <br /> Responsibility:, Orange County Planning and Inspections <br /> Taraet Date for Completion: FY 04-05 <br />' Status: To date, the Unified Development Ordinance (UDO) has not been completed. <br /> It is anticipated to be completed mid to late 2010. <br /> 3. Floodplain Mapping Projects <br /> Orange County continues to work with State and Federal agencies to complete new <br /> floodplain mapping within its jurisdiction. <br /> Orange County development regulations do not permit new structures to be <br /> constructed in floodplain areas. <br /> Responsibilitv: Orange County Planning and Inspections <br /> Target Date for completion: Unknown <br /> Status: The new FEMA FIRMs became effective�February 2, 2007. The County <br /> continues to work with State and Federal agencies on map maintenance within the <br /> jurisdiction. <br /> 4. Decrease Density in Protected Water Supply Watersheds <br /> Current reviews of existing housing densities in protected water supply watersheds are <br /> being performed. This work will most likely be connected with the preparation of the <br /> new Land Use Element of the Comprehensive Plan. <br /> Reducing density in rural areas should reduce vulnerability to several hazards, <br /> including wildfires. <br /> Responsibility: Orange County Planning and Inspections <br /> Tarqet Date for Completion: FY 2004-05 <br /> Status: With the adoption of the 2030 Comprehensive Plan, densities in the critical <br /> watershed areas will not be increased. <br /> Analvsis <br /> Complete removal of risk from several identified hazards is realistically not possible to <br /> achieve. For example, tornados can occur anywhere in the region, so restricting <br /> development in an area where a tornado had "touched down" in the past is not likely <br /> an effective mitigation measure for this hazard. A more effective mitigation measure <br /> would is to enforce wind velocity provisions in building codes, which Orange County <br /> does. Even so, a very strong tornado would be expected to damage or destroy some <br /> 53 <br />
