Oak#13 can be seen at the upper left; recommend removing it due to encroachment and excessive cankering(see photo below). Nearly all on-site trees are located along the perimeter of the property or on the developed north half, where they will not be directly affected by the t ` proposed house. The exceptions include a valley oak r, '` (#13) immediately south of the proposed home. In :t addition to dripline encroachment by the proposed $ 4 porch and house, the tree#13's condition also warrants its removal (Figure 2). It has sustained either physical or biological injury over the years, with nearly the entire circumference of its trunk girdled by . '" ~ 44i'' cankers. Multiple seasons of cankers are visible, and the tree does not appear to be healthy enough to . .k, ` 'k j1 overcome this chronic issue. I recommend removing t the tree to accommodate the proposed home.. '� Y s I also recommend removing the significantly drought- ., f • �, k stressed, trunk-cankered redwoods (#6 & 7) along the • - - : • ,a west property line. Replacing these young trees will ; !ptmoi �' y be more cost-effective than attempting to restore their `; •: - health. Other trees (#2, 10-12, 33, 34 & 259) will be � -:; . =` removed for proposed landscaping improvements. -;;'r' A valley oak (#23)was originally slated for removal Figure 2. Oak#13 is suffering from severe trunk due to proximity of the proposed cabana and pool cankers which recur and coalesce. It is also located 3'from the porch of the proposed home.
