Stanley Boulevard. Pleasanton <br /> Dear Mr. DiDonato: <br /> This report presents the results or a noise and vibration assessment study for the planned <br /> single-family developmerI along Stanley. in Pleasanton, as shown on the S'te Plan. Ref. <br /> (a). The noise exposures at the site v,vere evaluated aganst the standards of the City of <br /> Pleasanton General Plan Noise Element- Ref (b). he railroad induced ground vibration <br /> levels were evaluated against guidelines established by the Federal Transit Administration <br /> (Fl A). Ref. (c). An analysis of he on-site noise measurements indicates that the noise <br /> environment is created primarily by traffic sources on Stanley Boulevard and railroad <br /> operations on the adjacent Union Pacific Railroad/Altamont Commuter Iispress line. The <br /> results of the study Ieveal that noise exposure and noise level excesses occur and <br /> mitigation measures evil be required. The study also revealed that ground-borne <br /> vibration levels within the planned structures will exceed the criteria established by the <br /> FTA. <br /> Sections I and II of this report contain a summary of our findings and recommendations. <br /> respectively. Subsequent sections contain site. traffic. railroad and project descriptions. <br /> analyses and evaluations. Appendices A_ 13 and C contain the list of references_ <br /> descriptions of the star dards. definitions of the terminology. descriptions of the <br /> instrumentation used lbr the field survey. ventilation requirements. general building shell <br /> controls and the on-sift noise and vibration measurement data and calculation tables. <br /> MEMBER ACOUSTICAL SOCIETY O°AMERICA NATIONAL COUNCIL OF ACOUSTICAL CONSULTANTS <br />
