2.Revisions to the Draft EIR the project applicant shall conduct an off-site noise study to determine the project's contribution to off-site roadway noise and contribute its fair-share to mitigate the established noise impact. The following edits have been made on page 4.J-26 of the Draft SEIR: Mitigation Measure 4.J-5c: Any locations of outdoor activity for sensitive uses associated with the project site shall be designed so that the noise exposure from traffic does not exceed 65dB Ldn at these activity areas. This shall be done thru site orientation (i.e., location of activity areas away from roadways or shielded by project buildings)or with the inclusion of appropriate noise barriers. Prior to PUD approval Before building d, the project applicant shall be required to submit an acoustical analysis demonstrating that outdoor activity spaces associated with sensitive uses do not exceed 65 dB Ld,1 within these spaces. The following edit has been made on page 4.J-25 to the last paragraph, second sentence: Given a worst-case exterior-to-interior noise level reduction of 20 dB provided by project buildings, interior noise exposure could be 45 dB Ldn or higher within some project buildings. The following edits have been made on page 4.J-28 of the Draft SEIR: Mitigation Measure 4.J-7: For residential developments at Sites 9, 10, 1 1-13 and 14 near - - - -1- -the - . = 1eft- hand pattern of Runway 25L,the City shall require a site-specific acoustical assessments to determine noise exposure, impact, and mitigation regarding aircraft single events. The assessments shall include the collection of aircraft single-event noise level data for no less than 48-hours on or in the vicinity of the given housing areas. If needed, aircraft- related single-event noise exposure shall nifty be mitigated to satisfy the applicable City of Pleasanton Code criteria of 50 dB Lmax(bedrooms)and 55 dB Lmax(other habitable rooms) using acoustically rated construction materials/systems.
