Estates Reservoir Replacement Draft Environmental Impact ReportCumulative Impacts, Growth Inducements and Other Topics Required by CEQAAir QualityImpact C-6: Cumulative construction emissions.The geographic scope of this resource area is the San Francisco Bay Area Air Basin. TheProject would result in temporary increases in criteria air pollutant emissions duringconstruction as well as potential exposure of sensitive receptors to diesel engine exhaustemissions from construction equipment and haul trucks. However, implementation ofmitigation measures, as developed by the Bay Area Air Quality Management District andthe California Air Resources Board, would mitigate the Project’s contribution to regionalair quality impacts. Therefore, the Project’s contribution to cumulative air qualityimpacts would be negligible.Other projects listed in Table 5-1 also have the potential to result in the same types of airquality impacts as the Estates Reservoir Project, with the extent of impact depending onindividual project characteristics. However, all planned and proposed projects in theregion are subject to BAAQMD regulations and the Clean Air Plan guidelines.Therefore, assuming implementation of appropriate mitigation measures for all projectsin the region, cumulative air quality impacts would be less than significant.Greenhouse Gases (GHG)The geographic scope of this resource area is the San Francisco Bay Area Air Basin andthe Earth.As discussed in Chapter 3, the Project would not impede the State’s ability to meet its2020 greenhouse gas emissions goal. Implementation of specific measures to reduceGHG from fuel combustion, in addition to diesel exhaust control measures (Air Quality)would reduce and sequester GHG associated with vehicle and equipment use. On goingmaintenance activities would remain the same, and permanently eliminating water use bythe fountains would also save water and electricity used to operate the fountain pumps.For these reasons, the Project would result in less than significant cumulative impacts onglobal climate change.Noise and VibrationImpact C-7: Cumulative construction noise and vibration impacts.The geographic scope of this impact area is the extent of sensitive receptors within a fewhundred feet of the Project’s staging areas/construction site.The Project would result in intermittent and temporary noise above existing ambientnoise levels due to construction activities in the Project vicinity. With implementation ofmitigation measures, outlined in Chapter 3, the Project’s short-term noise impacts wouldbe less than significant, although possibly still periodically and intermittently noticeablesb09_001.doc 5-9 7/22/2009
Estates Reservoir Replacement Draft Environmental Impact ReportCumulative Impacts, Growth Inducement and Other Topics Required by CEQAat the closest noise-sensitive receptors across Estates Drive, and adjacent to the reservoirsite. While there is a remote potential for the proposed Project to contribute toconstruction noise levels generated by the cumulative projects listed in Table 5-1, thedistant location of projects and uncertain construction timing suggests that the potentialfor cumulative noise impacts would be remote to non-existent.As previously described, EBMUD will coordinate with the appropriate departments ofthe neighboring jurisdictions and with other utility districts and agencies regarding theschedule and timing of construction projects that would occur near the Estates Reservoirsite. With early and ongoing coordination, EBMUD would avoid conflicts with otherprojects to the extent possible, and the Project’s contribution to cumulative constructionnoise impacts, as mitigated, would not be considered significant.Similarly, while excavation activities for the Project could generate perceptible vibrationlevels, implementation of mitigation measures (3.9-3) would reduce those impacts to aless than significant level. The distant location of other projects and uncertainconstruction timing suggests that the potential for cumulative vibration impacts would beremote to non-existent.5.3 Growth Inducement Potential and Secondary Effectsof GrowthThe CEQA Guidelines require that an EIR evaluate the growth-inducing impacts of aproposed action. A growth inducing impact is defined as follows:"The ways in which the proposed project could foster economic or populationgrowth, or the construction of additional housing, either directly or indirectly, inthe surrounding environment. Included in this are [public works] projects whichwould remove obstacles to population growth.... It must not be assumed thatgrowth in any area is necessarily beneficial, detrimental, or of little significance tothe environment." (Section 15126.2(d.)The environmental effects of a proposed project’s induced growth are secondary orindirect impacts. Secondary effects of growth can result in significant increased demandon community and public service infrastructure; increased traffic and noise; degradationof air and water quality; and conversion of agricultural land to urban uses.Growth-inducing effects can result from projects that remove obstacles to populationgrowth. Increases in population can tax existing community service facilities, requiringconstruction of new facilities that could cause significant environmental effects. TheCEQA Guidelines require analysis of the characteristics of projects that may encourageor facilitate other activities that could in turn significantly affect the environment, eitherindividually or cumulatively. The CEQA Guidelines also encourage analysis of housingimpacts, including displacement of substantial numbers of existing housing or people,necessitating the construction of replacement housing elsewhere.sb09_001.doc 5-10 7/22/2009
