Noise Impacts on Adjacent Properties The development of commercial and residential uses on the property will generate added urban noise, such as traffic, loading and unloading of delivery trucks, children playing, etc. However, given the existing noise levels produced by nearby freeway and street traffic, and the existing commercial and office uses in the area, noise levels will not change substantially from that currently experienced in the area. During operation, the commercial uses will be required to meet the City's Noise Ordinance. A mitigation measure of the SEIR required that the future projects analyze whether they would add off-site traffic noise in excess of 55 dBA as described in the SEIR and, if they did, the applicant would need to contribute its fair share to mitigate the noise impact. The noise study determined that the project would not add traffic noise in excess of 55 dBA. Therefore, the applicant is not required to provide mitigation for this item. Short-term construction noise would also be generated during construction. The SEIR included construction related mitigation measures (e.g., limiting construction hours, compliance with the City's Noise Ordinance, locating stationary construction equipment as far from occupied buildings as possible, etc.). Conditions of approval have been included to address these mitigation measures. Grading and Drainage The majority of the lot is relatively level with perimeter landscaped berms rising several feet high. Except for the podium garage excavation and removal of the landscaped berms, the applicant is proposing to generally maintain the existing grades on the property. Approximately 9,000 cubic yards of excess soil will need to be off-hauled from the site. The haul route will be subject to the approval of the City Engineer. Parking lot and roof drainage would drain into landscaped bioretention areas that would filter contaminants before entering the arroyos and, ultimately, the bay. As conditioned, staff finds the proposed grading and drainage plan to be acceptable and in compliance with applicable stormwater runoff requirements. Architecture and Design Apartment and Retail Buildings Staff believes that the proposed buildings are well designed and articulated. The building designs are "four-sided" with no side minimized with respect to articulation or detailing. Portions of the building walls would pop-in or -out to provide variation in the wall plane and break up the building mass. The rooflines of the buildings undulate and vary in shape/material to break up the building mass and add interest. Building walls vary in materials and colors to provide variety and interest. Although other apartment buildings constructed in Pleasanton may have more of a "residential" appearance, staff and the applicant did not want a significantly residential appearance for this PUD-85-08-1D-4 M Page - 18 - March 27, 2013
