The property owner is required to ensure the viability and long-term health of trees planted for replacement through proper care and maintenance for the life of the project. Replaced trees that do not survive must be replanted in the next appropriate season for planting. f. If all required replacement trees cannot be reasonably accommodated on the site, off -site tree replacement within the shoreline jurisdiction may be allowed at a site approved by the City. Priority for off -site tree planting will be at locations within the Transition Zone. If no suitable off -site location is available, the applicant shall pay a fee into a tree replacement fund per the adopted fee resolution. 5. Large Woody Debris (LWD). When a tree suitable for use as LWD is permitted to be removed from the shoreline buffer, the tree trunk and root ball (where possible) will be saved for use in a restoration project elsewhere in the shoreline jurisdiction. The applicant will be responsible for the cost of moving the removed tree(s) to a location designated by the City. If no restoration project or storage location is available at the time, the Director may waive this requirement. Trees removed in the shoreline jurisdiction outside the buffer shall be placed as LWD in the buffer (not on the bank), if feasible. Priority for LWD placement projects will be in the Transition Zone. E. Tree Protection During Development and Redevelopment. All trees not proposed for removal as part of a project or development shall be protected using Best Management Practices and the standards below. 1. The Critical Root Zones (CRZ) for all trees designated for retention, on site or on adjacent property as applicable, shall be identified on all construction plans, including demolition, grading, civil and landscape site plans. 2. Any roots within the CRZ exposed during construction shall be covered immediately and kept moist with appropriate materials. The City may require a third -party Qualified Tree Professional to review longterm viability of the tree. 3. Physical barriers, such as 6-foot chain link fence or plywood or other approved equivalent, shall be placed around each individual tree or grouping at the CRZ. Minimum distances from the trunk for the physical barriers shall be based on the approximate age of the tree (height and canopy) as follows: a. Young trees (trees which have reached less than 20% of life expectancy): 0.75 per inch of trunk diameter.
