EXHIBIT A <br />Resolution No. _____ Page 34 of 76 <br />Certification of the Magnolia at the Park EIR <br />City’s Municipal Code, which requires appropriate back fill, compaction of soils, and foundation design <br />to ensure stable soils. For the aforementioned reasons, the Project would result in a less than significant <br />impact related to unstable soil or geologic units. <br /> <br />In addition, the Project is not located on a geological unit or soil that would become unstable as a result <br />of subsidence. Subsidence is a general lowering of the ground surface over a large area that is generally <br />attributed to lowering of the groundwater levels within a groundwater basin. Subsidence or settlement of <br />the ground can occur as a result of earthquake motion in an area where groundwater in a basin is lowered. <br />Because the Project does not involve groundwater pumping, impacts related to subsidence will not occur <br />as a result of the Project. (Initial Study, p. 32.) This conclusion also applies, for the same reasons, to the <br />Modified Project. <br /> <br />9.6.4 Soil Expansion <br /> <br />Threshold: Would the Project be located on expansive soil, as defined in Table 18-1-B of the <br />Uniform Building Code (1994), creating substantial risks to life or property? <br /> <br />Finding: Less than significant impact. (DEIR, p. 2-6; Initial Study, pp. 32-33.) <br /> <br />Facts in Support of Finding: The Project would not be located on expansive soil. Expansive soils contain <br />certain types of clay minerals that shrink or swell as the moisture content changes. As described above, <br />the Project site soils consist of silty fine to medium sands with local layers of fine to coarse sands with <br />gravel size rock and some larger rock fragments, which have a low expansion potential. (Initial Study, p. <br />32.) In addition, as noted above, the Project would be required to have building foundations and pavement <br />areas constructed in compliance with the CBC and the City’s Municipal Code, which requires appropriate <br />back fill, compaction of soils, and foundation design to ensure stable soils. Thus, the Project’s impacts <br />related to expansive soils would be less than significant. (Initial Study, p. 33.) This conclusion also <br />applies, for the same reasons, to the Modified Project. <br /> <br />9.6.5 Septic Tanks <br /> <br />Threshold: Would the Project have soils incapable of adequately supporting the use of septic tanks <br />or alternative wastewater disposal systems where sewers are not available for the disposal of wastewater? <br /> <br />Finding: No impact. (DEIR, p. 2-6; Initial Study, p. 33.) <br /> <br />Facts in Support of Finding: The Project site is currently connected to the City’s sewer system, and the <br />Project would also connect to existing sewers and would not use septic tanks or alternative wastewater <br />disposal systems. As a result, impacts related to septic tanks or alternative waste water disposal systems <br />would not occur from implementation of the Project. This conclusion also applies, for the same reasons, <br />to the Modified Project. <br /> <br />9.7 Greenhouse Gas Emissions <br /> <br />9.7.1 Greenhouse Gas Emissions <br /> <br />Threshold: Would the Project generate greenhouse gas emissions, either directly or indirectly, <br />that may have a significant impact on the environment? <br />2-64
