Mr.Jolley February 13, 2020 Page 11 of 15 significance, statewide or locally, for what constitutes a wasteful, inefficient, and unnecessary consumption of energy for a proposed medical facility.Therefore, for the purposes of this analysis,the amount of energy necessary for Project implementation will be quantified and compared to that consumed in San Joaquin County as a whole. Task 2E: Noise The evaluation of noise impacts associated with the proposed Project will be completed by senior-level staff members who are noise experts, accounting for intervening structures and specific distances between Project noise sources and sensitive receptors. The analysis would be supported by modeling documentation, which would be included as an attachment to the technical noise report. The applicable noise and land use compatibility criteria for the Project area will be reviewed and noise standards regulating noise impacts and land use compatibility will be discussed for land uses adjacent to, and nearby, the Project site. Such lands include those administered by the County of San Joaquin in addition to the City of Stockton (lands in the City of Stockton will be potentially be affected by Project transportation-related noise). In order to establish the existing ambient noise levels currently experienced in the vicinity, a site visit will be conducted, and short-term noise level measurements (lasting 15 minutes) at up to five separate locations will be taken in the Project area, and one long-term noise level measurement (lasting 24 hours)will be taken on the Project site. Construction would occur during implementation of the proposed Project. Noise impacts from construction sources will be analyzed based on the anticipated equipment to be used, horsepower, and percentage of time in use. The construction noise impacts will be evaluated in terms of hourly equivalent continuous noise levels (Leq).The analysis will rely on the Federal Transit Administration Roadway Construction Noise Model. In addition to construction noise, an analysis of vibration impacts will be based on the California Department of Transportation's 2013 vibration analysis guidance. Analysis requirements will be based on the sensitivity of the area and specific construction activities. The proposed Project would be a source of onsite stationary noise (e.g., mechanical equipment, parking lot activities, helicopter take-offs, etc.) and offsite mobile noise (e.g., automobile traffic and flying helicopters). The SounclPLAN 3D noise model and the AEDT software will be used to calculate noise levels from Project onsite noise sources. A noise contour graphic will be prepared to depict the noise levels at the surrounding receptors. The modeling results and noise contour graphics will be discussed and summarized in the analysis. Offsite mobile source noise impacts from groundborne traffic will be assessed using the U.S. Federal Highway Traffic Noise Prediction Model (FHWA-RD-77-108), while the assessment of offsite mobile source noise from flying helicopters will rely on the FAA AEDT software. (In addition to emission quantification, the AEDT software system estimates aircraft noise by leveraging GIS and relational database technology.) Task 2F: Traffic The traffic study will be performed by KD Anderson (KDA) as described in the scope provided below. 11 ECORP Consulting,Inc. EN'l'ERONIIENTAL IONSI:LTRN-ll
