Page 3 <br /> <br /> 3. Future Noise Impacts <br /> <br /> We will determine if noise mitigation is necessary to reduce noise <br /> levels in outdoor use areas to the Cityts noise goal. This <br /> assessment will compare future traffic noise projections obtained <br /> from Task 2 with the City~s goals. As you know, t~e City of <br /> Pleasanton in its Noise Element of the General Plan recommends <br /> that noise levels in outdoor use areas not exceed an Ldn'of 60 dB. <br /> We will summarize to what extent homes will be exposed to levels <br /> in excess of the Cityts goal. <br /> <br /> 4. Noise Barrier ... <br /> <br /> Based on the identified future noise impacts, we will recommend <br /> the height, length, and location of a noise barrier to reduce <br /> noise levels in outdoor use areas to the Cityts goal. Our <br /> analysis would graphically show the location of the noise barrier <br /> and tabulate the noise reduction. achieved for each home along the <br /> roadway. This analysis will require roadway and residential pad <br /> elevations to facilitate accurate noise barrier height and length <br /> determinations. We assume that the City Engineer will be able to <br /> provide this information. However, if necessary, we can provide <br /> an engineering survey of the area. This work would be in addition <br /> to the outlined scope and could be negotiated as part of a final <br /> contract. <br /> <br />charles m. salter associates, inc. <br /> <br /> <br />
