<br />Resolution No. PC-95-90 <br />Page 11 <br /> <br />i) Perimeter berms shall be brought to the face of the soundwall with the <br />crest of the berm located approximately three feet (3' 0") higher than <br />the base height of the soundwall, with the toe-of-slope located <br />approximately two feet (2') higher than the base height of the wall. <br />The lower two feet (2') height of the soundwall would, therefore, <br />function as a retaining wall for the berm. <br /> <br />ii) Barrier and screen planting shall be installed on the crest of berms <br />and/or between berms and the wall. Planting as to type, location, and <br />groupings shall function as a privacy screen for rear yards as well as <br />further buffering the appearance of the soundwall to the public rights- <br />of-way. <br /> <br />iii) Low planters shall be installed at the inside and outside corners of the <br />soundwall facing Gibraltar Drive and Stoneridge Drive. <br /> <br />These measures shall be implemented with the final design of the site, <br />grading, and landscape plans for review and approval by the Planning Director <br />before issuance of a building, on-site, and grading permits. <br /> <br />1. To achieve compliance with the noise standards of the Noise Element of the <br />Pleasanton General Plan -- exterior limit of sixty (60) dBA Ldn, an interior <br />limit of forty-five (45) dBA Ldn -- for single-family homes, the following <br />measures will be implemented by the applicant in the design of the project's <br />proposed site plan and the design and construction of the proposed units: <br /> <br />i) A six foot (6' 0") tall solid barrier shall be constructed along all rear <br />property lines facing Stoneridge Drive and Gibraltar Drive. The <br />barrier height will be referenced from the elevation of the building pad. <br /> <br />ii) To prevent sound "flanking" around the ends of walls at openings, e.g., <br />at the project's entrances off San Marcos Way and Rialto Way and the <br />EVA entrance off Stoneridge Drive, the barrier shall be extended back <br />from the edge of the PSE line a distance of 110'. Implementing this <br />requirement will also affect fences for Lots 41, 42, 43, 87, 88, 89, 90, <br />104, 105, 106, and 110. <br /> <br />II <br /> <br />. <br />
