. TRAV ER SCS - - : • -- TREE SERVICE WHEN IT HAS TO BE DONE RIGHT January 7, 2019 Erin Sorgel esorgel(a�gmail.com Re: Revised Arborist Report for 481 Sycamore Road, Pleasanton Dear Erin, This arborist report addresses the proposed project at 481 Sycamore Road. Per the City of Pleasanton's Tree Preservation Ordinance Chapter 17.16, the scope of work includes: • Tag, identify and measure trees with a diameter of 6" or greater on or overhanging the property. • Note trees that are considered "Heritage" per city ordinance, defined as: o Any single-trunked tree with a circumference of 55" or greater (17" in diameter), measured 4.5' above ground. o Any multi-trunked trees of which the two largest trunks have a circumference of 55" (17" diameter) or more. o Any tree 35' or more in height. o Any tree of particular historical significance specially designated by official action. o A stand of trees, the nature of which makes each dependent upon the other for survival or the area's natural beauty. • Identify dripline locations and tree numbers on site plan. • Assess individual tree health and structural condition. • Assess proposed improvements for potential encroachment. • Based on proposed encroachment, tree health, structure, and species susceptibility, make recommendations for preservation. • Provide appraised values for all trees whose driplines may be encroached. This report was revised to address the city's comments. Changes are noted with "revised 1/7/19". Project Discussion The property is currently developed with a single-family home to the north, which is separated from the undeveloped south portion by an existing wire fence. The proposed project will develop the open area with a new residence, served by a new driveway that extends the existing driveway (Figure 1). Many landscaping improvements are also proposed throughout the entire property, including but not limited to a pool & cabana, new hardscape, fencing and walkways. I included fifty-six (56) trees in my inventory, eighteen (18) of which are considered Heritage trees per City ordinance. Eighteen (18) trees are dead or nearly dead but were included per city request. I also noted four (4) trees on the neighbor's property since their canopies are overhanging the site. However, they will not be affected by the proposed project. (revised 1/7/19) 4080 Cabrilho Drive •Martinez, CA 94553 • Telephone(925)930-7901 Fax(925) 723-2442
