Dingee Pressure Zone Improvement Project - Estates Reservoir Replacement ProjectWater Distribution Facilities - Initial StudyPotentiallySignificantImpactLess ThanSignificant WithMitigationIncorporatedLess ThanSignificantImpactf) For a project within thevicinity of a private airstrip,would the project exposepeople residing or workingin the project area toexcessive noise levels?a,b,c&d) Normal operation of the reservoirs would not generate noise that exceeds ambient noise levels.NoImpact Although EBMUD is not subject to local jurisdiction zoning ordinances for projects involving the storage ofwater (refer to section 53091 of California State Planning, Development, and Zoning Regulations), EBMUDstrives to be consistent with local noise ordinances during construction, where feasible and not contrary to itspublic purpose and responsibilities.Construction activities associated with the project will elevate noise levels for short/intermittent intervals duringthe construction period which is anticipated to extend from 18 to 24 months. For example, trucks are anticipatedto arrive every ½ hour for concrete pours on the new tanks. Back-up alarms on the trucks generate noise levelsof approximately 75 dBA-weighted decibels at 200 feet away. Elevated noise level is dependent on the numberand pieces of equipment to be used and the intensity of the activities, and will vary over the construction period.In recognition of the residential neighborhood setting, EBMUD will limit construction activities to the hours of7:00 AM to 7:00 PM weekdays. Weekend and overtime work requires prior approval of EBMUD and is limitedin practice to critical construction segments or unforeseen emergencies. Residents will be notified in advance ofany weekend or overtime work deemed essential.Construction related truck-trips would increase noise along haul routes to the sites, but this would only besignificant for the segments within existing residential communities. These trips should occur during work hoursand during the workweek; therefore this impact is considered less than significant because of its short-termnature.The project would not involve pile driving. However, removal of the concrete reservoir liner and processing ofconstruction debris into loose materials for on-site reuse may create temporary increases in noise levels andgenerate ground level vibration. The benefit to processing and re-using construction material on-site would befewer truck trips and truck traffic to the site, than if the demolition debrisPotentially significant impacts associated with construction activities are fully explored in the Project Draft EIR,and mitigation measures are proposed to reduce impacts.e&f) Neither the Estates or Dingee project sites is located within an airport land use plan, or is within two miles of apublic airport or a private airstrip.sb09_003.doc 26 12/10/08

POPULATION ANDHOUSING.Would the project:a) Induce substantial populationgrowth in an area, eitherdirectly (for example, byproposing new homes andbusinesses) or indirectly (forexample, through extensionof roads or otherinfrastructure)?b) Displace substantial numbersof existing housing,necessitating theconstruction of replacementhousing elsewhere?c) Displace substantial numbersof people, necessitating theconstruction of replacementhousing elsewhere? a) The project will not induce population growth by making additional water supply available for newdevelopment. The project refurbishes and replaces existing facilities to improve water quality and reliability ofthe existing water distribution system that currently serves customers in the City of Piedmont and Oakland. Onlyplanned growth, approved and permitted by these two cities will be served by these improved facilities.b) No housing presently exists at the project site; therefore, the proposed project would not displace housing.c) The project would not displace people or housing from the site and no relocation would be required.For the reasons stated above (a&b), there are no impacts to Population and Housing and no further analysis and/ormitigation measures are identified in the Project Draft EIR.sb09_003.doc 27 12/10/08
