The Legislature further finds and declares that the breaches in the Napa River levees have caused a major sewerline to be covered by tidal waters, which could lead to serious water pollution in sensitive wildlife habitat areas in the event of leakage or breakage, to problems of infiltration of tidal waters into the sewerline, and to damage of wetlands during the normal maintenance of the sewerline. The breaches also allow the flooding of State Highway Route 37 and nearby developed areas which has already caused damage in excess of one million dollars ($1,000,000) and threatens to cause additional damage in the future.
