Vulnerability Assessment Worksheets for Jefferson County are located in the back of the
Technical Appendix. These worksheets represent the loss estimates for each hazard
affecting the county, including the communities listed above.
Loss estimates were calculated using a combination of information found below. Rough
economic estimates were also included.
• The number of buildings was based on the recorded number of buildings from the
assessor’s database.
• Values of buildings represent the market value, rather than the dollar loss likely to
result from a given event. Building damages could range from minimal to total
devastation.
• The number of people was derived from the 2000 U.S. Census, EWG, and Office of
Social and Economic Development (OSEDA) databases.
• Dollar figures were based on county assessor’s data and Saylor Construction Cost
Index data.
• Sources for these worksheets include the Missouri Department of Elementary and
Secondary Education, Economic Development, Missouri Department of
Conservation, Missouri Office of Economic Data Analysis; county assessor’s data,
Saylor Construction Cost Index, and EWG databases.
• Projected figures were calculated using the above numbers and factoring in
population projection percentages from the community profile.
