i) Perimeter berms shall be brought to the face of the soundwall with the crest of the berm located approximately three feet (Y 0") higher than the base height of the soundwall, with the toe-of-slope located approximately two feet (2') higher than the base height of the wall. The lower two feet (2') height of the soundwall would, therefore, function as a retaining wall for the berm. ii) Barrier and screen planting shall be installed on the crest of berms and/or be- tween berms and the wall. Planting as to type, location, and groupings shall ~mction as a privacy screen for rear yards as well as further buffering the ap- pearance of the soundwall to the public rights-of-way. iii) Low planters shall be installed at the inside and outside comers of the soundwall facing Gibraltar Drive and Stoneridge Drive. These measures shall be implemented with the final design of the site, grading, and landscape plans for review and approval by the Planning Director before issuance of a building, on-site, and grading permits. · i. To achieve compliance with the noise standards of the Noise Element of the Pleasan- ton General Plan -- exterior limit of sixty (60) dBA Ldn, an interior limit of forty-five (45) dBA Ldn -- for single-family homes, the following measures will be imple- mented by the applicant in the design of the project's proposed site plan and the de- sign and construction of the proposed units: i) A six foot (6' 0") tall solid barrier shall be constructed along all rear property lines facing Stoneridge Drive and Gibraltar Drive. The barrier height will be referenced from the elevation of the building pad. ii) To prevent sound "flanking" around the ends of walls at openings, e.g., at the project's entrances off San Marcos Way and Rialto Way and the EVA entrance off Stoneridge Drive, the masonry soundwall shall be extended back from the edge of the PSE line a distance of 110'. Implementing this requirement will also affect fences for Lots 41, 42, 43, 87, 88, 89, 90, 104, 105, 106, and 110. iii) Noise attenuation for buildings' interiors shall implement the recommendations identified in the "Traffic Noise Assessment Study for the Planned 'Hacienda Area B Cluster Housing Development, Stoneridge Drive, Pleasanton," by Ed- ward L. Pack Associates, Inc., Project No. 24-087-3, dated August 7, 1995 to the satisfaction of the Planning Director. Mitigation measures shall be worked out at the tentative map stage.
