Staff Recommendation: Staff supports the structure of the initial approvals. <br /> <br />23. Flood Control Management <br /> <br />Issue: <br /> <br />The project does not incorporate a sufficiently wide setback from the Arroyo <br />de la Laguna to allow an "environmentally sensitive" channel widening <br />capable of achieving upstream flood protection. <br /> <br />Proposed Project: Provides a setback for one of many possible channel widening <br /> options for five years. Requires San Francisco and Pleasanton to urge <br /> upstream options which do not require additional San Francisco property. <br /> <br />Alternatives: <br /> <br />Increase setback "reserve" by another 200+ feet. <br />Require the plan to conform to a Zone 7 master plan and reserve land for it <br />if adopted within five (other) years. (see #12, above). <br />Phase development of the project so that a 300-foot wide area along the <br />Arroyo is the last years' phases to develop; redesign golf course so it is not <br />adjacent to Arroyo and is compatible with a future residential corridor <br />between the Arroyo and golf course if the land is not needed for a flood <br />control project. <br /> <br />Discussion: <br /> <br />The setback proposed is for a trapezoidal channel with no substantial <br />revegetation (similar to upstream channels). Zone 7 believes the setback is <br />insufficient both to allow a channel to be built which would not cause <br />upstream flooding and to get necessary regulatory agency permits. Staff <br />continues to note that Zone 7 is still working on the factual information <br />which will form the basis for selecting a master plan option; options <br />remain which would not require significant work in this reach of the <br />Arroyo. A wider setback could enable construction of a vegetatively lined <br />or fully vegetated new channel, capable of passing the design flood <br />without causing upstream flooding. Staff believes even this type of <br />project will have difficulty receiving permits and is contrary to General <br />Plan policy and City Council direction to preserve the existing riparian <br />corridor. Nonetheless, City policy also favors reducing/eliminating flood <br />risks. Phasing the project to preserve viable options is possible. However, <br />these are best done if the golf course is rerouted, since it will be built in an <br />early phase and cannot be moved once homes are built along one side of it. <br />Routing the golf course along the Arroyo was a desired result during the <br />Preferred Plan concept process, but it could move eastward. Zone 7's <br />master plan process could be lengthy. Once final options are developed, a <br />CEQA process and financing plan are necessary. Staff believes it is <br />reasonable to complete this process within five years. <br /> <br />Substantive Issues/Alternatives Page 26 June 9, 1999 <br /> <br /> <br />
