Project costs of this alternative are estimated at $5,589,000including $1,160,327 in estimated land rights costs, as detailed on Table 30.Although this alternative eliminates many of the flood damages in the watershed,the benefit to cost ratio (B/C ratio) for this alternative is low (0.34) due to manyoverlapping project benefits for the same floodprone structures.Exhibit 35: Alternative D9 - Combine Alternatives C7, C8 and S11111
