Data Documentation Template and Earthquake Checklist Earthquake Data Analysis Methodology: Structural Retrofits of Buildings This data documentation template is designed to assist Benefit-Cost (BC) analysts in recording the data and methodologies utilized in their Benefit-Cost Analysis (BCA). BC analysts should keep in mind that a well-documented BCA means that a knowledgeable BC analyst should be able to re-create the BCA from the supporting documentation provided (with a Mitigation application submitted for funding) without any additional explanation. BC analysts should provide an electronic or paper copy of the full BCA to compliment any template or summary submitted to FEMA for review. Check with your State Hazard Mitigation Officer or FEMA Regional office to find out if a completed Data Documentation Template (DDT) is required with your grant application. This data documentation guidance and the Earthquake Full Data Module are intended for BCA of structural seismic mitigation projects for buildings. For non-structural seismic mitigation projects do not use the Full Data Module. Rather, use the Non-Structural Module and see the non-structural data documentation template. Data Type Value Description Documentation Source Discount Rate The OMB- mandated discount rate of 7% must be used for all BCAs. * The discount rate determines the time-value of money * In a FEMA benefit-cost analysis, a discount rate is used to calculate a value today (the Net Present Value) of future benefits so that they can be compared to the costs of a mitigation project. * Electronic or paper copy of the BCA. * The OMB-mandated discount rate of 7% must be used for all BCAs. * The OMB-mandated discount rate of 7% must be used for all BCAs.

FEMA BCA Checklist Appendix II FEMA BCA Checklist Last Updated June 28, 2006 For the entire BCA Checklist, refer to the BCA_Checklist.doc located on the BCA Mitigation Toolkit (BCA Mitigation Toolkit\4 – BCA TOOLS\CHECKLIST AND DATA DOCUMENTATION TEMPLATES). 3.7 Seismic Mitigation Project 3.7.1 A seismic structural engineer should be consulted for designing structural or non-structural seismic mitigation projects. (c) For FEMA statistical values for injuries and deaths, use the Inflation Calculator (located in the BCA Tools main folder) to inflate values from the 2001 values listed in Section 2.3 of the FEMA “What is a Benefit?” document ($2,710,000 for a death, $15,600 for major injury, and $1,560 for minor injury) to the current year. If the FEMA standard values are over-ridden, the application will need to include documentation on the source of the data and justification of why the data is more appropriate than the standard data. However, if the default values for injuries and deaths are only adjusted to the current year values, no documentation is required. Structural EQ_DDT.doc Page 1 of 9 {Last Updated 7/6/06}
