holes as needed. Start augur holes at three times the trunk diameter, i.e. 6-feet from a 24-inch tree. Back fill with amended soil, based on an agronomic lab's testing and recommendations. • Prior to construction, mulch all exposed soil areas using a topical application of a well -composted, coarse -texture mulch, without manure or bio-solids, e.g. Aguinaga Forest Floor'/2 to 11/2" particle size. Apply it 2-inches deep, but not against the tree trunks. • Deep water before construction and check soil moisture monthly during construction by means of a soil test probe. Slow water with a soaker hose or water spike for 12 hours, or as long as necessary to reach 4-feet deep. • Rinse tree foliage at the end of each work week, using a strong stream of water from a high- pressure nozzle. • During construction in areas without pavement near the preserved trees, 3 or more inches of coarse mulch or tree chips under 1-inch plywood for light vehicle parking and steel plates for larger vehicles is required to prevent compaction and protect surface roots. • Protection Barrier: A protection barrier shall be installed around the trees to be preserved. The barrier shall be constructed of durable fencing material, such as chain link fencing. The barrier shall be placed as far from the base of the tree(s) as possible and shall be maintained in good repair throughout the duration of construction, and shall not be removed, relocated, or encroached upon without permission of the Project arborist. o Storage of Materials: There shall be NO storage of materials or supplies of any kind within the area of the protection barriers. Concrete and cement materials, block, stone, sand and soil shall not be placed within the drip -line of the tree. o Fuel Storage: Fuel storage shall NOT be permitted within 150 feet of any tree to be preserved. Refueling, servicing and maintenance of equipment and machinery shall NOT be permitted within 150 feet of the protected trees. o Debris and Waste Materials: Debris and waste from construction or other activities shall NOT be permitted within protected areas. Wash down of concrete or cement handling equipment, in particular, shall NOT be permitted within 150 feet of protected trees. • Any damages or injuries should be reported to the Project arborist as soon as possible. Severed roots shall be pruned cleanly to healthy tissue, using proper pruning tools. Broken branches or limbs shall be pruned according to International Society of Arboriculture Pruning Guidelines and ANSI A-300 Pruning Standards. However, even with implementation of the PDF-I and Mitigation Measure AES-1, the Project would still result in a substantial difference in scale, height, and property setbacks that is considered significant pursuant to the City's criteria. As a result, impacts related to existing visual character or quality of the site would be significant and unavoidable. (DEIR, pp. 4.1-16 through 4.1-26.) Consistent with the methodology in the EIR, photo -simulations were also prepared to demonstrate the degree of visual change that would result from implementation of the Modified Project. The photo - simulations show that, as described in the FIR, the Modified Project would alter the existing views by development of forefront residential buildings that would result in a substantial difference in scale, height, and property setbacks that is considered significant pursuant to the City's criteria related to visual character from specific viewpoints. However, the Modified Project would be lower in height and smaller in scale than the Original Project. The contrast in views that would occur from implementation of the Modified Project is less than what would occur from the Original Project. Thus; although impacts related to specific viewpoints would remain significant and unavoidable, no new or greater impacts would occur from implementation of the Modified Project.
