MEMORANDUM October 7, 1975 TO: FROM: SUBJECT: Honorable Mayor and Members of the City Council Director of Planning Comments on Solid Waste Management Plan and Draft EIR Environmental Factors - Sanitary Landfills There are several short-comings with respect to the Draft Plan's environmental analysis of landfill sites. The first has to do with the synthesis of the various environmental faStors into a generalized "environmental constraints" map; the second concerns the lack of any consideration toward the degree of risk should environmental degradation unexpectedly occur; the third concerns the location of sites visa vis other uses. "Environmental Constraints" Map. The map used in the Draft Plan is the same as the "Selected Physical Information for Alameda County, California" map. Adopting this map for pur- poses of the Draft Plan introduces the designation of "Q," or quarry land, while nowhere does the Draft Plan's environmental analysis consider quarries as different from other land. If land on the map is designated "Q," analysis of that land for sanitary landfill purposes should be undertaken. Otherwise, the land should be designated according to its environmental factors. Because Of the continuing proposals to utilize played-out graval quarries as landfill sites, a generalized environmental discussion of these proposals should have been undertaken as part of the Draft Plan and EIR. Pleasanton applauds the recom- mendation that each proposed solid waste facility be subjected to the EIR process but feels that a generalized analysis and recommendation with respect to the gravel quarries in the Amador- Livermore Valley should be contained in the Management Plan. While the "Q" designation in the Amador-Livermore Valley does not show the existence of any environmental constraints, a cursory analysis shows these sites would receive an "unsuitable" rating according to the preliminary suitability evaluation in the following areas: (1) partially within flood-prone areas; (2) partially within 1,000 feet of a water-supply stream (Arroyo del Valle surface water feeds the Niles Cone water supply of the A.C.W.D.); (3) partially within 500 feet of a lake utilized for recreation (Shadow Cliffs); (4) within 1,000 feet of a major groundwater basin recharge area; (5) bottom surface below the ground water level; (6) soil permeability of greater than 2 inches per hour; (7) located in an area underlain by unconsoli- dated deposits and susceptible to severe shaking; and (8) arti-
