This report is intended to identify all the trees within the plan area that could be affected by the proposed project. The inventory contains all the trees six inches in diameter and greater measured at forty-eight inches above grade. The assessment consists of 233 trees comprised of 22 different species with black acacia (Acacia melanoxylon) and accounting for nearly a quarter of all specimens on site. Ninety-five trees are growing within the assumed setback outside the buildable area while the remaining 138 specimens are located within the interior. There are 65 “Heritage Trees” with only one coast live oak (Quercus agrifolia) and four deodar cedars (Cedrus deodara) while the remaining 168 are not large enough to qualify for the “Heritage Tree” designation. Most of the trees assessed are in fair condition while twenty-six are in good shape, twenty-five poor, and three are dead. There are 5 trees with good suitability for conservation which are the 4 deodar cedars and 1 coast live oak, 43 fair, 183 poor, and 3 are dead. Based on what has been provide the entire site would be cleared and no trees retained. The result would be the loss of 233 trees (65 “Heritage Trees” and 168 others). At this point there is no “Tree Protection Plan” and there are no trees designated for conservation. Once the design is finalized and there is an indication of what trees are to be retained, if any, a proper tree protection plan can be created. The average LU Value was calculated at 3.47 for all trees assessed and the table is listed in Appendix B.
