APPENDIX 1 <br /> TREE PROTECTION GUIDELINES <br /> The following guidelines build upon the recommendations of San Joaquin County. The <br /> guidelines also incorporate ideas garnered from several other sources: the California Oak <br /> Foundation, the University of California: Cooperative Extension,Integrated Hardwood <br /> Range Management Program, Sunset Magazine's oak issue (10/1990), Fremontia's oak <br /> issue (11/90), and Nelda Metheny of Hortscience. These guidelines apply only to the <br /> housing, recreation, equestrian, and infrastructure zones (1,2,3 and 4). They are not <br /> applicable to the nature preserve or agricultural areas unless specified. <br /> 1. A licensed arborist will work with design engineers in planning the development, <br /> before the site plan is prepared. The arborist or consultant will identify and flag all trees of <br /> sapling and tree size classes on each lot within 20 feet of the building pads, water lines <br /> (including fire standpipe, well site, septic system) and road. All native trees including oak, <br /> buckeye, cottonwood and willow will be evaluated for health and structural condition. <br /> Trees suitable for preservation and potential hazard trees will be identified,mapped and <br /> flagged. A tree is any plant having the potential to grow to tree size,over 20 feet; however <br /> saplings may be small, measuring less than 2 inches in diameter and 2 to 4 feet in height. <br /> Before construction begins, it is important to have the trees in the most healthy,vigorous <br /> condition possible so they can withstand the inevitable stress of construction activities. <br /> Pruning Trees. Prune to remove dead wood and end-weights of unusually heavy limbs. <br /> End-weight removal should be done in such a manner that the cut leaves a lateral branch of <br /> at least 1/3 the diameter of the removed portion. No stub cutting should be allowed. <br /> Leaving stubs as well as excessive pruning is not only unsightly but encourages vigorous <br /> watersprout growth which is susceptible to mildew. Excessive pruning can also result in <br /> sunburning of exposed limbs,poor branching structure, and added maintenance costs. <br /> Buckeye Ranch Resource Plan (November, 1993) <br /> 253 <br />
