b. Protect roots of heritage trees through measures suggested in the Heritage Tree Ordinance and the project landscape guidelines. A qualified arborist should be present during road grading activities to suggest and perform measures necessary to preserve trees. Trees which are to be preserved shall have fences constructed around the entire tree at the dripline prior to grading and construction activities and shall be maintained through the duration of grading and construction activities. (modification of MM 6a) c. No more than three additional heritage trees may be removed due to roadway grading and construction, building pad grading and other site preparation activities, not including landslide repair measures. (MM 6b) d. Lot 61: Removed trees shall be replaced at a six to one ratio with local native species, in a variety of sizes ranging from 15-gallon to 36-inch box. These trees shall be located along the westerly and northerly property lines to help screen the proposed house, provide privacy for the adjacent neighbor and to re-establish the biotic balance of the tree stand. These trees shall be installed prior to occupation of the home. (MM 6c, part 2) e. All trees, but especially the heritage and smaller oak trees, shall be preserved to the greatest extent possible. Tree preservation measures shall be outlined in a Tree Preservation Plan, to be prepared by a qualified arborist, and approved by City staff. Where removal of trees for construction or grading for home sites is unavoidable, trees shall be replaced at a six-to-one ration, with the replacement trees to be a combination of native l5-gallon, 36-inch and 48-inch box trees. These trees shall be located so as to screen the proposed homes from view, and to re-establish any biotic relationships with the existing stands of trees from trees were removed. (MM 6d) f. In all cases where a heritage tree is incorporated within the lot and street landscaping of the development, or a heritage tree occurs immediately adjacent to a site designated for grading, no grading or vehicle soil compaction shall occur within four feet of the outer leaf circumference of the tree. Trees which are to be preserved shall have fences constructed around the entire tree at the dripline prior to grading and construction activities and shall be maintained through the duration of grading and construction activities. This zone shall be identified plainly by a series of four foot high stakes flagged with orange tape and placed at 6 foot intervals around this zone. In addition, no high use human activities shall be placed under large heritage oaks (this restriction also shall be incorporated into the project landscape guidelines and homeowners' CC&Rs).
