NOP - Notice of Preparation

Document Description
The Metropolitan Water District of Southern California will be Lead Agency for the preparation of an EIR to assess the environmental effects of rehabilitating an existing blow-off structure along Metropolitan's treated water pipeline in Newport Beach. The project site is located just north of the San Diego Creek Flood control channel, south of Bayview Way, between Jamboree Road on the west and State Route 73 on the east. The blow-off structure's valves and piping were intalled at the time of the pipeline's original construction during World War II and have gradually deteriorated, necessitating repair and maintenance of the structure.
