table format, and includes the date, type of event, location, damages, other information, and data source for each listing. Blank boxes within the table indicate that the particular information was not available. Total Values at Risk from Hazards These figures were obtained from each county's Assessors office - a participant of each County Planning Subcommittee (CPS). The figures are included because many of the hazards present an equal risk across the entire county. It is unlikely, and unexpected, that a natural hazard would destroy the total value of property within a county. However, because the CPS cannot determine where a hazard will strike in the county, and which property/infrastructure or what percent of property/infrastructure will be impacted, listing the total value of the property/infrastructure at risk was deemed the most reasonable approach of detailing "what is at risk." In most cases assessed values were listed, due to the format of the available data. Floods are the only hazard addressed in this plan where the CPS can determine where they will strike, what will be impacted, and a reasonable estimate of the value of the damage. This is why each NFIP participating community conducted a detailed floodplain inventory. Floodplain InventoryNulnerability and Associated NFIP Data NFIP Mapping Information Listed are the names of all incorporated communities within each county, and the current status of mapping within the NFIP. If the community has been mapped, the Community Map # and the Effective Date is cited. Inventory: In communities with NFIP maps, the CPS counted every residential, commercial, and manufactured building within the identified Special Flood Hazard Area (SFHA). In most cases a CPS team member, accompanied by a Certified Floodplain Manager (CFM), did this manually. In some instances, CADD or GIS maps showing lots and building footprints were utilized. In other cases, communities could provide a listing of properties within the SFHA In Sterling/Atwood (Logan County), figures from engineering studies for proposed mitigation projects were utilized. The addresses of each building were then taken to the County Assessor's office where the individual property cards were pulled and the values of the improved structures were recorded. In a few counties, the Assessor's office was able to produce a digital listing of the properties and their values. The individual values were then totaled to arrive at a total value of property at risk. Actual values were listed. The actual values were utilized because they provide a more accurate picture of what it would cost to repair or replace the damaged properties. The actual values were calculated by "adding back in" the % deducted in calculating "assessed values." In Colorado in 2001, residential property was assessed at 9.15%. All commercial property is assessed at 29%. Only Real Property and Improvement values were used. Land values were not included in the calculations, because land is uninsurable, and generally not damaged, in floods. Finally, using NFIP depth-damage curves from FEMA's Riverine Flood Benefit-Cost software program, an average % of damage was calculated. This was done because 49
