and species to be acceptable. Staff notes that the landscaping shown along the Stanley Boulevard frontage and private street entrance cannot be installed as shown since Stanley Boulevard will be widened and a new sidewalk will be installed. A condition of approval requires the frontage landscaping be adjusted to accommodate the City's planned Stanley Boulevard street improvements. Fencing and soundwall elevations and locations have been shown on the fencing exhibit, Sheet L2 (the soundwall heights on the fencing exhibit need to be modified to conform to the height requirements of the noise study). An 8 -ft. tall precast concrete soundwall would be installed along the rear property lines of Lots 5, 6, 7, and 9 and along the rear and eastern side property lines of Lot 8. A 6 -ft. tall wood sound fence would be installed along the rear property lines and street side yards of Lots 1 and 14. Standard 6 -ft. tall solid wood "good neighbor" fencing would be installed along the rear property lines of the other lots. Standard 6 -ft. tall solid wood "good neighbor" fencing or 4 -ft. solid wood fencing with 2 -ft. of lattice on top would be installed along the side property lines and side fence returns. The street side fences on Lots 1 and 14 facing Stanley Boulevard would be setback five feet from the back of the future City sidewalk in order to provide adequate room for frontage landscaping. Evergreen vines would also be installed along the southern side of these street side fences. Staff finds the fence and soundwall designs and locations to be acceptable. Driveway Material The landscape plan shows scored concrete material for the driveways while the civil plans indicate that asphalt will be used. In order to reduce the impervious area of the project, delineate the driveway areas from the drive aisles, and improve the aesthetics of the project, staff has included a condition that scored permeable paving or decorative concrete pavers be used for the driveways. Tree Removal A tree report has been prepared that specifies the species, size, health, and value of the existing trees on the site that exceed six - inches in diameter. A total of 20 trees would need to be removed to accommodate the development, including 12 "heritage- sized" trees (i.e., a tree which measures 35 feet or greater in height or which measures 55 inches or greater in circumference). Tree species to be removed include deodar cedar, Italian stone pine, Douglas fir, CA black walnut, English walnut, coast live oak, Canary Island date palm, glossy privet, almond, orange, and lime. A fruitless mulberry tree in the City right -of -way along the project frontage will also be removed as part of the Stanley Boulevard reconstruction project. Two nearby trees located in the Union Pacific Railroad corridor would be preserved. In July 2010, the current property owner requested to remove the three heritage -sized deodar cedar trees due to safety concerns with large falling branches. The City hired an arborist to conduct a thorough examination of these trees. The attached report by HortScience dated July PUD -82 Page - 21 - September 15, 2010
