Preconstruction Meeting Required. Prior to the commencement of any permitted clearing and grading activity, a preconstruction meeting shall be held on site with the permittee and appropriate city staff. The project site shall be marked in the field as follows: 1. The extent of clearing and grading to occur; 2. Delineation and protection of any critical areas and critical area buffers with clearing limit fencing; 3. Flagging of trees to be removed and tags on trees to be retained; and 4. Property lines. B. Placing Materials Near Trees. No person may conduct any activity within the protected area of any tree designated to remain, including, but not limited to, operating or parking equipment, placing solvents, storing building material or stockpiling any materials, or dumping concrete washout or other chemicals. During construction, no person shall attach any object to any tree designated for protection. C. Protective Barrier. Before development, land clearing, grading, filling or any land alteration, the applicant shall: 1. Erect and maintain readily visible temporary protective tree fencing along the limits of disturbance which completely surrounds the protected area of all retained trees, groups of trees, vegetation and native soil. Tree protective fencing shall be a minimum height of three feet, visible and of durable construction; orange polyethylene laminar fencing is acceptable. 2. Install highly visible signs spaced no further than 15 feet apart along the entirety of the protective tree fencing. Said sign must be approved by the director and shall state, at a minimum, "Tree and Soil Protection Area, Entrance Prohibited," and provide the city phone number for code enforcement to report violations. 3. Prohibit excavation or compaction of soil or other potentially damaging activities within the barriers; provided, that the director may allow such activities approved by a qualified professional and under the supervision of a qualified professional retained and paid for by the applicant. 4. Maintain the protective barriers in place for the duration of the project until the director authorizes their removal. 5. Ensure that any approved landscaping done in the protected zone subsequent to the removal of the barriers shall be accomplished with machinery from outside the protected zone or by hand. 6. Limit the time period that the critical root zone is covered by mulch, plywood, steel plates or similar materials, or by light soils, to protect the tree's critical root zone. 7. In addition to the above, the director may require the following: a. If equipment is authorized to operate within the protected zone, the soil and critical root zone of a tree must be covered with mulch to a depth of at least six inches or with plywood, steel plates or similar material in order to protect roots and soil from damage caused by heavy equipment. b. Minimize root damage by hand -excavating a two -foot -deep trench, at edge of critical root zone, to cleanly sever the roots of trees to be retained. Never rip or shred roots with heavy equipment. c. Corrective pruning performed on protected trees in order to avoid damage from machinery or building activity. d. Maintenance of trees throughout construction period by watering and fertilizing. D. Grade. 1. The grade shall not be elevated or reduced within the critical root zone of trees to be preserved without the director's authorization based on recommendations from a qualified professional. The director may allow coverage of up to one-half of the area of the tree's critical root zone with light soils (no clay) to the minimum depth necessary to carry out grading or landscaping plans, if it will not imperil the survival of the tree. Aeration devices may be required to ensure the tree's survival. 2. If the grade adjacent to a preserved tree is raised such that it could slough or erode into the tree's critical root zone, it shall be permanently stabilized to prevent soil erosion and suffocation of the roots. 3. The applicant shall not install an impervious surface within the critical root zone of any tree to be retained without the authorization of the director. The director may require specific construction methods and/or use of aeration devices to ensure the tree's survival and to minimize the potential for root -induced damage to the impervious surface. 4. To the greatest extent practical, utility trenches shall be located outside of the critical root zone of trees to be retained. The director may require that utilities be tunneled under the roots of trees to be retained if the director determines that trenching would significantly reduce the chances of the tree's survival. 5. Trees and other vegetation to be retained shall be protected from erosion and sedimentation. Clearing operations shall be conducted so as to expose the smallest practical area of soil to erosion for the least possible time. To control erosion, it is encouraged that shrubs, ground cover and stumps be maintained on the individual lots, where feasible. 6. The director may approve the use of alternative tree protection techniques if those techniques provide an equal or greater degree of protection than the techniques listed in this subsection. TREE PROTECTION NOTES, CONT'D E. Directional Felling. Directional felling of trees shall be used to avoid damage to trees designated for retention. F. Additional Requirements. The director may require additional tree protection measures that are consistent with accepted urban forestry industry practices. [Ord. 4227 § 1 (Att. A), 2021; Ord. 4�IES U B (Att.
