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 J6-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 15-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). No root pruning within the dripline or crown pruning of any heritage trees to be affect by grading, landslide repair or building pad preparation shall occur. (modification of MM 6f) g. All lots which have a downhill segment adjacent to heritage tree sites shall have a cement curb-type drain installed along the length of its border. Summer surface run-off water from lawn and yard watering shall be shunted by the curb drain to a storm water system and away from the root zone of the oaks. In addition, drought-resistant native landscaping shrubs and trees shall be used for the homesites, rather than water-demanding exotic species. (MM 6g)
