the City limits). The field data will establish the baseline existing noise environment and will be used to validate the traffic and modeling conducted for the EIR. Construction Noise and Vibration Assessment Construction impacts with implementation of the project will be evaluated at a programmatic level for the General Plan. Future noise and vibration effects from construction activities will be discussed in terms of industry -standard analysis techniques (such as from the U.S. Federal Transit Administration) and using programmatic guidelines regarding typical scheduling, equipment mix, hauling, and truck trips for expected development. Feasible mitigation measures will be identified to minimize future construction -related impacts in the study area. Long -Term Operational Impacts An evaluation of long-term noise and vibration impacts from the operation of the proposed uses will be provided based on the proposed land use designations and future anticipated transportation improvements for the area. Future roadway-, railway-, and airway -related noise in the City will be analyzed. As with the existing conditions, future roadway -related conditions will be assessed using a version of the U.S. Federal Highway Administration Traffic Noise Model. The resulting noise level contours will rely on General Plan buildout traffic forecasts provided by IBI Group. The noise analysis will identify areas along roadway segments that would be exposed to noise level increases above the City's impact criteria. Existing and Future Noise Contour Map To graphically summarize the overall, existing and future community noise environments throughout the city, a comprehensive noise level contour map will be generated by PlaceWorks technical and GIS staff. This future conditions map will included noise levels associated with the major roadways and railways in (or near) the city as well as pertinent portions of the SNA noise levels (primarily affecting the SR -55 corridor, west of Red Hill Avenue). For rail- and aircraft - related future noise conditions, we will use published information sources concerning projected changes in rail movements and aircraft operations. Stationary Noise Impacts Noise impacts from nontransportation sources such as major commercial/light-industrial uses will be discussed in terms of potential impacts to nearby noise -sensitive receptors. Other, nontransportation noise sources in the City (such as such as HVAC units, maintenance activities, and periodic truck movements) are expected to be of secondary importance to the traffic -related impacts, and these other sources will be discussed qualitatively. Future noise environments will be discussed for the proposed uses in the plan area, and noise mitigation (include a supplemental recommendations for self -mitigating Noise Element policies) will be provided to reduce potential impacts to future sensitive land uses related to noise, if applicable. Noise and Vibration Technical Study The results of the technical analyses described above will be compiled into the Noise and Vibration Technical Study to be used in the General Plan Update EIR. Pertinent calculation/modeling details will be provided in an appendix. PlaceWorks has included up to eight hours to address comments from the City on the draft technical study report. Meetings PlaceWorks noise and vibration technical staff will attend, as appropriate, the following meetings and public hearings: Kick-off meeting 3 progress meetings/conference calls with City Staff October 17, 2018 Page 8
