� � J - City itself. B. Identification of Geological Hazards As more specifically set forth in the Seismic Sa£�ty Element of the General Plan the principal geologically related hazards are: 1) The quaternary land slide areas in the Emerald Lakes-Redwood City Hillside Area. 2) The earth fill dams retaining the Upper and Lower Emerald Lakes. 3) Bay mud underlain baylands without adequate and proper site preparation. C. Identification of General Safety Hazards 1) Potential flooding in lower areas of the City given high run- off, high tides, and power interruption to pumping stations. 2) Flooding in flood zones adjacent to major drainage courses such as Redwood Creek, especially the high value central area northeasterly of the Southern Pacific R.R. tracks, and from the northwesterly city limits to Cedar Street. 3) Other flood hazard areas. 4) Absence of adequate parallel emergency routes to Bayshore � Freeway or E1 Camino Real. 5) Absence of grade separations of the Southern Pacific R.R. as it passes through Redwood City, with potential for delay of emergency vehicles. 6) Seismically unproved highway. -grade separations o�er maj-or circulation routes with potential for route blockage in event of collapse in a major earthquake. D. Nature and Magnitude of Effort Required to Correct or Mitigate Hazards The City of Redwood City and its citizens can do many things to correct or mitigate identified safety hazards. However, many hazards cannot be corrected or mitigated without authority, cooper- ation or funding from the County, State, or Federal governments. For example, elimination of all flooding hazards identified by the Department of Housing and Urban Development in connection with the new flood insurance program is of such a magnitude that effort and funding from the Federal and/or State government would be required to effect meaningful mitigation measures. The City could not possibly allocute the required funding to this project category alone. The same observation can be made with regard to correction of the Southern Pacific R.R. grade crossing elimi- nation problem� Implications of such a program are far-reaching, and would involve major economic costs to both the private and government sectors.
