The Legislature further finds and declares that it is in the public interest to provide flood protection to the residents and property surrounding White Slough, to relocate the flooded sewerlines in White Slough, and to enhance the ecological values of South White Slough, even though those improvements require some fill in tidal and tidally influenced wetlands. The Legislature further finds and declares that the United States Army Corps of Engineers has studied the flooding problems of White Slough and has identified the construction of levees protecting existing filled or developed lands north and south of State Highway Route 37 as an environmentally sound and economically feasible method of providing flood protection, together with a combined improved transportation route and flood control levees along State Highway Route 37.
