Curves related to business contents, steel <br />structures, vehicles, streets and utilities, and, railroads will use existing in-house data, <br />supplemented by interviews where appropriate.' Ciiives for street and utility damage will be based <br />on in-house data supplemented by discussions with the City/Utility engineers. <br /> <br />f. OTHER DAMAGE RELATIONSHIPS. . . Other damage relationships which will be <br />developed in order to determine average annual damages include' emergency costs, Flood <br />Insurance Administration costs, and transportation costs. Other categories such as agricultural <br />damages and recreation losses are not expected to apply, based on the reconnaissance <br />investigations. The relationships will be developed in the following manner: <br /> <br />(1) Emergency costs will be developed based on expenditures during previous floods. <br />These will be supplemented by data from other areas and interviews with the appropriate <br />agencies. <br /> <br />(2) Flood Insurance Administration costs will be estimated based on administrative <br />costs and Federal Emergency ManagemenfAdririnisrration (FEMA) estimates of the participation <br />rate. <br /> <br />(3) Transportation costs will be derived based on interviews with railroad personnel <br />where rail traffic is intermpted. Impacts on vehicular traffic will be based on traffic counts, and <br />the flood-induced change in travel mileage and travel time in accordance with current regulations. <br />This will include the impacts of bridge or channel collapses, where the estimated time to replace <br />them will be made in conjunction with City engineers. <br /> <br />g. EXISTING CONDITION DAMAGES. The existing condition damages provide the <br />baseline from which to determine alternative benefits. The field data and depth-damage <br />relationships will be entered into the Albuquerq~esort program, which integrates depths at the <br />structure, reach, and flood plain. Preliminary average annual damages and single occurrence <br />damages shall be determined by combining' the damage curves with the inventory by reach and <br />flood plain and integrated through the LA damages program. The final calculations will be made <br />using risk analysis (see item m). <br /> <br />h. FUTURE CONDITION DAMAGES. The future condition damages show the changes <br />from the present condition and are the baseline from which to determine future alternative benefits. <br />Future growth is assumed to be elevated to the FEMA 100 year flood elevation, since El Paso <br />participates in the flood insurance program. <br /> <br />i. AVERAGE ANNUAL EQUlV ALENT DAMAGES. The average annual equivalent <br />danlages will be derived by integrating the existing condition damages and the future condition <br />danlages, using the Corps' required interest rate at the time of the study. <br /> <br />j. <br /> <br />POST PROJECT CONDITIONS. The average annual post project conditions will be <br /> <br />SECTION B, PAGE 15 <br />
