Contents are defined as carpeting, furniture, draperies, personal belongings, plus maintenance associated with the clean up of first floors and basements. 6. Average depth in the business district was 1.5 feet and 2.0 feet, for the 10-and 100-year frequencies, respectively. Flood Damage Results The structures 1 isted in Table 8 were found to be lying within the 10- and 100-year flood prone areas. The depth of flooding can be directly related to dollar damages by using depth/damage ratios. These ratios have been deter- mined by FEMA using actual insurance claim infonnation from past flood events. The data is separated into various types of single-family and business struc- tures. The two categories of residential structures applicable to those sub- ject to fl oodi ng in the Town of Ordway were single-family frame, with and without basements. For depths of 1-, 2-, and 3-feet the percent of value attributable to flood damages is 10-, 14-, and 26-percent for structures without basements; and 20-, 22-, and 28-percent for structures with basements, respect i ve ly . No calculations were made for loss of business contents or business structure damage. It is anticipated that only minor cleanup to the various Orcway businesses which lie within the flood prone areas would occur, and "JK1 therefore, only the value of contents damaged by flooding would apply. ~ For the ratios stated, and the assumptions listed in the Basis of Flood Damage, it has been calcualted that approximately $153,000 and $342,000 worth ~ of flood damages could occur during a 10- or 100-year event, respectively. On ~ an annual basis, damages associated with this level of flood damages has been roughly estimated to be $54,000. This value will later be used to compare against the annual cost of the improvements.
