Damages to crops, equipment, and hay stored in the field for all alternatives are presented in
Table 18 below. The methodology for the computation of the damages to each category is the
same as explained in the “Without Project” discussion previously presented. It should be noted
that under “Damages (Computed)” risk and uncertainty was computed separately for the
categories of Crop Damage, Equipment Losses, and Storage. The second part of the table below
titled “Damages (Mean and Standard Deviation) was computed using the composite of all
categories in the risk and uncertainty evaluation and is the basis for computing the average
annual damages.
