Estates Reservoir Replacement Draft Environmental Impact ReportSummaryENVIRONMENTALIMPACT MITIGATION MEASURESCultural ResourcesImpact C-4: Cumulativeincrease in cultural resourceimpactsAs described in Chapter 3, the Project would permanently eliminate a historic resourcerecommended for CRHR listing, and would have a significant and unavoidable impact to culturalresources even after mitigation (recording and documenting the roof and features). Therefore theProject would contribute to cumulative cultural resources impacts for the City of Oaklandspecifically, and for Alameda County and the State of California, secondarily.SIGNIFICANCEAFTERMITIGATIONLess than SignificantTraffic and CirculationImpact C-5: Cumulative trafficand roadway disruptions.There are a number of approved and pending projects in the City of Oakland, as detailed on the Cityof Oakland’s October-November 2008 project list that could potentially increase traffic in the studyarea. Traffic from those projects in combination with traffic from the proposed Project could resultin cumulative traffic impacts.Less than SignificantPrior to construction, EBMUD will coordinate with the appropriate departments of the surroundingjurisdictions and with other utility districts and agencies regarding the timing of constructionprojects that would occur near the Estates Reservoir site. Such coordination would help to minimizemultiple traffic and circulation disruption in the same areas. EBMUD would also submit plansrelated to, and comply with the requirements of, encroachment permits with local jurisdictions (ifrequired) which would provide further opportunities to coordinate multiple projects. Specificmeasures to mitigate significant impacts would be determined as part of the interagencycoordination. Upon completion of the Project, traffic generated by site construction activity wouldreturn to current levels; thus the cumulative traffic impact is less than significant. Similarly, whileexcavation activities for the Project could generate perceptible vibration levels, implementation ofmitigation measures (3.9-3) would reduce those impacts to a less than significant level. The distantlocation of other projects and uncertain construction timing also suggests that the potential forcumulative vibration impacts would be remote to non-existent.sb09_001.doc S-23 7/22/2009
