_�� <br />NORTHWEST VIEW -3 YEARS <br />Grading and Drainage <br />The northern portion of the site slopes upward from south to north. The elevation difference is <br />approximately eight feet. Grading would be performed to create a pad area for the building and <br />patio dining. A two- tiered retaining wall is proposed to be constructed along the portion of site <br />that abuts the 1 -580 EB Hopyard Road off -ramp. As the northern portion of the site was <br />Caltrans surplus land, an existing Caltrans storm drain line runs diagonally across the property. <br />The proposed development includes the relocation of this storm drain line along the northern <br />property line and creating an easement. Bio- retention areas are proposed along the retaining <br />walls, near the patio dining area, and along the westerly property line. The project would be <br />required to conform to all applicable stormwater requirements. <br />Tree Removal <br />An arborist report, dated March 11, 2013, was prepared by Arbor Resources (included as <br />Exhibit D) and discusses the existing trees on the project site. A total of 34 trees (comprising <br />five tree species) were surveyed. Among the 34 survey trees, 16 are defined as heritage -sized <br />trees per the City's Tree Preservation Ordinance (five coast redwood trees, two coast live oak <br />trees, and nine eucalyptus trees). Table 2 below shows the species and quantities of the <br />surveyed trees. <br />Table 2: Surveyed Trees <br />Species <br />Quantity <br />Percentage of Total <br />Coast live oak <br />3 <br />9% <br />Coast redwood <br />9 <br />26% <br />Holly oak <br />10 <br />29% <br />White alder <br />3 <br />9% <br />Eucalyptus <br />9 <br />26% <br />Total <br />34 <br />P13- 2533/PUD- 100/PUD- 96- 13 -02M <br />Page 11 of 27 <br />Planning Commission <br />
