Construction traffic to the site would vary by type of activity andconstruction phase. Peak truck traffic is associated with concrete deliveries for the flooror roof slab, as each pour is a one day operation. The same truck traffic peak isanticipated during the process of importing fill to complete the grading plan. During thedemolition phase, total truck haul trips away from the site are expected to be less thanone-half that estimated for the construction phase, but involves an equal or slightergreater amount of worker vehicle traffic than that estimated for the construction phase.sb09_001.doc 2-13 7/22/2009
Estates Reservoir Replacement Draft Environmental Impact ReportProject DescriptionAdditional traffic generation information is detailed in Section 3.6 and Table 3.6-5 ofthis EIR.Construction ActivitiesConstruction activities would also require the use of on-site power and water sources,temporary light poles, storage of petroleum products in above ground tanks (for examplehydraulic fluids and lubricants); pumps, hoses and temporary pipelines to deliver water tothe construction area; and water tank trucks, dust control operations and other equipmentand activities (construction trailers) required to support the construction process.Excavation at shallow depths (less than about 15 feet) is expected to be accomplished usingstandard earthmoving equipment; depths greater than 15 feet may require the use of jackhammers, hoe rams or drilling equipment. Some equipment will be on-site for specifiedperiods (e.g., dozers, hoe-rams and concrete breaking/crushing equipment while otherequipment such as backhoes, loaders, and maintenance vehicles would be present during allconstruction phases. During the pumping plant upgrade, temporary, outdoor pumps willlikely be utilized, until pump replacement is completed.Fencing and Work Area DelineationThe existing permanent six-foot perimeter chain link security fence will be replaced witha taller fence of similar material and color, in same location. Temporary security fencingwithin the site may be required during construction to delineate work areas, but will beremoved when construction is completed. An on-site construction office trailer(s) will belocated near the Estates Drive entrance, inside the existing gate.Staging and Stockpiling ActivitiesDuring the course of construction, the contractor will be required to store and stageequipment and materials (concrete forms, scaffolding, etc.) and demolition debris on-site.Stockpiles would typically be less than 40 feet in height from the bottom of the existingbasin (i.e., no taller than the existing roof structure) and would be managed using erosionand dust controls to minimize dispersal of dust.Deliveries of construction equipment, cement, drainage rock, reinforcing steel and concretewould occur throughout construction, however, the majority of the concrete deliveries arerequired for construction of the two tanks and the concrete landscape wall. Fueling andmaintenance of construction equipment would occur daily, as required, and within theapproved work hours.2.4.3 Operating CharacteristicsInstrumentation is provided to remotely operate and monitor the pumping plant and reservoirsystem. However the site and facilities would continue to be routinely inspected byEBMUD’s Operations and Maintenance staff, EBMUD contractors and Pacific Gas andElectric Company (PG&E), and used periodically for job-site reporting by field personnelsb09_001.doc 2-14 7/22/2009
