Potential noise sources associated with the subject project will be identified. The source power levels from any project -related mechanical equipment will be obtained from the corresponding equipment manufacturers by the City and/or project proponent and provided to URS for inclusion in the noise analysis. The projected noise levels emanating from this equipment will be calculated and the potential for impact to adjacent noise sensitive land uses will also be determined. An analysis will be made of the potential noise due to on -site traffic related sources. This will include noise from vehicles in the proposed parking lot, vehicle alarms, and delivery trucks. Impacts from these sources on the existing adjacent land uses will be identified. Short-term (construction related) noise sources associated with the proposed project will be identified and assessed and noise impacts will be determined. This will include noise and vibration from various types of construction equipment expected to be used at the site, including the use of pile driving equipment. The type of piles and pile driving equipment proposed to be used for this project will be examined and the potential for impacts to the surrounding community will be determined. This assessment will examine the adjacent land use as well as the distance to the pile driving activity. Should the use of noise mitigation measures be required for either short-term or long-term project related impacts, a series of specific noise mitigation measures will be developed (including types, locations, sizes, materials) which will reduce the impact of project related noise levels to meet the applicable exterior noise standards at the surrounding noise sensitive land uses. This may include a noise and vibration monitoring program to measure the potential impacts of construction noise to the existing residences adjacent to the project site. or recommendations to the types of piles and drivers used during construction. A noise technical report will be prepared documenting the results of the noise measurement survey, detailing the findings of impact, the mitigation measures necessary to reduce those impacts, and level of significance. e. Traffic Study URS understands that a traffic study has already been prepared for another project that was proposed on the project site per our conversation with Shahir Gobran of the City's staff on this matter. Mr. Gobran thought that enough information was available in that study to determine the traffic impacts of the proposed commercial project. We have already requested an electronic copy of the traffic report for URS' review. We are assuming at this time that enough information is available from the existing report to determine the commercial project's impacts on traffic on Harbor Boulevard and the surrounding area and to fill out the project Initial Study. m
