Relocation of eight residences would be the most severe long-term adverse effect. This alternative proposes to employ flood plain zoning in the area from Datura east to Powers Park. The long-term adverse effects in this reach of the study area would be as discussed in ALTERNATIVE NO.1. ALTERNATIVE NO. 3 Beneficial Effects Short-term benefits would be nearly the same as ALTERNATIVE NO.2. This proposal is identical with ALTERNATIVE NO.2 for the main tributary, with the addition of an improved detention embankment in Powers Park. This would greatly reduce the potential flood danger between the Park and Datura Street. The proposed improvements along the south tributary would decrease potential flood damage to one half the present potential. Flood insurance benefits would be available to property owners within the Powers Park-Datura reach and along the south tributary. Adverse Effects Again, noise levels during construction would be a short-term adverse effect. As in ALTERNATIVE NO.2, relocation would be required, and the long-term effects of flood plain zoning would occur. INTERIM REPORT RECOMMENDATION Beneficial Effects The beneficial effects of the Interim Report Recommendation would nearly duplicate those of ALTERNATIVE NO.1 for the main tributary and those of ALTERNATIVE NO. 3 for the south tributary. Adverse Effects The effects of flood plain zoning in the Recommendation would be as previous- ly discussed. It is also felt that implementation of the Interim Report Recommendation would have an adverse effect in view of the more positive flood prevention solutions found in ALTERNATIVES NO.2 and 3.
