Estates Reservoir Replacement Draft Environmental Impact ReportTraffic and Circulationbuses, pedestrians, and bicyclists. Based on the significance criteria, these impacts areconsidered significant.Mitigation Measure 3.6-1: EBMUD contract specifications shall requirepreparation and implementation of a Traffic Management Plan, and collaborationwith the City and California Highway Patrol, as appropriate. The Plan shall includethe following elements:The work hours for each phase of Project construction, the process for notifyingresidents of construction activity, and the means for people to reportconstruction-related problems.A haul route, based on the route shown on Figure 3.6-5 that shall be provided toall trucks serving the site during the construction period. Should therecommended one-way truck access route not be implemented and trucks routedto Estates Drive south of the Project site, sufficient capacity would exist onEstates Drive south of the Project site to accommodate additional traffic volumesassociated with the peak construction period. However, a flagger would berequired at the Estates Drive/Park Boulevard intersection to direct traffic thoughthat intersection with an alternative routing plan.Flaggers at the site entrance and at the curve on Estates Drive immediately westof the Project site to improve traffic safety during regular construction hours.Flaggers at the Moraga Avenue/Estates Drive intersection during regularconstruction hours.A peak-period flagger (7:00 a.m. - 9:00 a.m. and 4:00 p.m. - 6:00 p.m.) at theLa Salle Avenue/Moraga Avenue intersection.Control and monitoring of construction vehicle movements through theenforcement of construction specifications by EBMUD on-site inspectors.Signage on Estates Drive and La Salle Avenue warning motorists of theconstruction work ahead.Unimpeded through access to the Montclair Pumping Plant site at all timesduring reservoir construction.The Traffic Management Plan shall be enforced by EBMUD constructioninspectors.Significance after Mitigation: Impact 3.6-1a Significant and Unavoidable.Impact 3.6-1b Less than Significant.Impact 3.6-2: Construction of the proposed Project would generate a demand forparking to accommodate worker vehicles.Approximately eight worker vehicles could park on Estates Drive on the dirt shoulderadjacent to the Project site. This level of on-site parking supply is not expected to be ableto accommodate the projected worker parking demand during the majority of constructionphases should parking not be provided on the interior of the site. Limited on-streetparking is provided in the vicinity of the Project site and construction vehicles should notsb09_001.doc 3-6.19 7/22/2009
Estates Reservoir Replacement Draft Environmental Impact ReportTraffic and Circulationbe parked on the neighborhood streets for extended periods of time. This impact isconsidered significant but can be mitigated to less than significant.Mitigation Measure 3.6-2: EBMUD shall provide designated on-site parking areas toaccommodate all Project-related parking demand. In the earlier construction phaseswhen there may not be sufficient space on-site to accommodate all parking demand,EBMUD contract specifications will require the contractor to secure private off-siteparking and provide shuttles to bring workers to and from the Project site.Significance after Mitigation: Less than Significant.Impact 3.6-3: Project construction would cause increased wear-and-tear onroadways used by construction vehicles to access the Project site.Large trucks would be used to haul material to and from the Project site. Althougharterials such as Moraga Avenue and Mountain Avenue are designed to withstandsubstantial truck volumes, minor residential roads such as La Salle Avenue and EstatesDrive are not. These roadways would likely experience increased wear-and-tear as aresult of Project construction.The residential roadways around the Project site are not designed to accommodate highvolumes of heavy vehicles and the addition of construction traffic could degrade roadwayconditions in the immediate study area. This impact is considered significant but can bemitigated to less than significant.Mitigation Measure 3.6-3: EBMUD contract documents will require that roadconditions shall be documented for all routes that would be used by constructionvehicles both before and after Project construction.Significance after Mitigation: Less than Significant.ReferencesAlameda-Contra Costa Transit District Bus System Map, available online athttp://www.actransit.org/Caltrans, Truck Networks on California State Highways, available online athttp://www.dot.ca.gov/hq/traffops/trucks/truckmap/truckmap-d04.pdfCaltrans, Truck Route List, available online athttp://www.dot.ca.gov/hq/traffops/trucks/truckmap/truck-route-list.xlsCity of Oakland, CEQA Thresholds/Criteria of Significance Guidelines, (July 15, 2008)http://www.oaklandnet.com/government/ceda/revised/AttachH.pdfsb09_001.doc 3-6.20 7/22/2009
