The proposed action includes a variety of structural and non-structural measures. Structural measures involve a 1 1/2 mile underground conduit and deep tunnel, temporary storage areas, one permanent impoundment, channel modifications, embankments, floodwalls, and culverts and weirs. non-structural measures are floodplain evacuation, flood proofing and continuation of the existing floodplain regulation and flood insurance programs. Construction would result in aesthetics loss, long-term adverse impacts on existing vegetation and short- and long-term impacts on aquatic ecosystems. The extended periods of inundation would temporarily affect recreational opportunities in some areas. (Author).
