<br />, ' <br />I' <br />, <br />l <br /> <br />27. EVALUATION OF RURAL DAMAGES <br /> <br />a. Rural flood damage estimates were based on information acquired <br />through field surveys, combined with or augmented by data compiled by <br />the United States Bureau of Reclamation and the United States Soil <br />Conservation Service. In many areas of the basin, post-flood survey <br />data were correlated with data'on flood ~amage potentials developed <br />in previous flood control investigations. These latter data were <br />used to estimate damages attributable to lOBS of crop production <br />outside the flooded areas due to loss of irrigation water supplies. <br />It is recognized that the extra moisture> prevalent in these areas <br />during June and July of 1965 would tend to offset losses from impaired <br />delivery of irrigation'water. However, the drought conditions of <br />the 1966 season in the affected region indicate that crop losses <br />associated with impaired storage capability may far exceed the <br />compensation from extra direct rainfall moisture which was available <br />during June and July of 1965. <br /> <br />b. The estimates of rural losses include farmstead damages, <br />crop losses, damages to irrigation works and related loss of crop <br />production. Losses to the electrical distribution systems and <br />telephone systems, and such flood-related expenditures for debris <br />removal, dead livestock disposal, measures to preserve public health, <br />and flood-fighting activitie,s have been tabulated in s\UDJnaries of <br />rural damages as miscellaneous iteins '. The estimates of. rural damages <br />include associated economic losses, the factors for which were <br />computed during flood control investigat.ions. These associated economic <br />losses reflect the estimated reductions in rural economic activity <br />associated with losses in agricultural production. <br /> <br />28. EVALUATION OF TRANSPORTATION DAMAGES <br /> <br />The category of transportation damages includes physical damages <br />to city streets and bridges, State and Federal highways, roads and <br />bridges, and county roads and bridges. The category also includes <br />estimates of physical damages to railroads, trucking, freight cargo, <br />and the associated economic losses resulting from delays in freight <br />deliveries, traffic, re-routings, and other factors. The associated <br />economic losses attributed to damage and destruction of highway roads <br />and bridges were estimated in terms of traffic detours and delays. <br />Estimates were made by the Corps of Engineers of physical damages to <br />bridges, roads, and railroads, and of replacement and repair costs. <br />These estimates were correlated with estimates compiled by the State <br />Highway Department, county highway departments, and municipal departments <br />of public works. The losses resulting from traffic delays and detours <br />were estimated from standard vehicle charges, traffic density patterns, <br />and estimates of duration of bridge and road outages. Physical damages <br />to railroad facilities were obtained from the affected railroads. Esti- <br />mates of cargo losses and losses due to delay of freight deliveries <br /> <br />20 <br />
