(b) Tree Preservation. The proposed project shall be designed and sited to preserve <br />significant trees to the greatest degree attainable or feasible, with trees having the <br />following characteristics given the highest priority for preservation: <br />1. Healthy trees that have a reasonable chance of survival considering the base <br />zone or special area zone designation and.other applicable approval criteria; <br />2. Trees located within vegetated corridors and stands rather than individual <br />isolated trees subject to windthrow; <br />3.- Trees that fulfill a screening function, provide relief from glare, or shade <br />expansive areas of pavement; <br />4. Trees that provide a buffer between potentially incompatible land uses; <br />5. Trees located along the perimeter of the lot(s) and within building setback <br />areas; <br />6. Trees and stands of trees located along ridgelines and within view corridors; <br />7. Trees with significant habitat value; <br />8. Trees adjacent to public parks, open space and streets; <br />9. Trees located along a water feature; <br />10. Heritage trees. <br />There are 22 trees of varying types and age in the vicinity of the development. The application notes that <br />no trees are proposed for removal. A critical root zone analysis is provided.on Sheet L-1 which appears to <br />confirm that all trees in the area will be preserved. The applicant also shows tree preservation fencing to <br />ensure the preservation of the trees. To ensure none of the trees are damaged in the vicinity of <br />construction, the following conditions of approval are warranted. <br />Tree Preservation Plan (Sheet L-1.) with the final site plans shall include the following tree <br />preservation notes: <br />• "All protective tree fencing shall remain in place until completion of all construction <br />activities." <br />• "Protective fencing for trees identified to be preserved shall be inspected and approved <br />by the City prior to beginning any construction related activities. <br />• "No excavation, grading, material storage, staging, vehicle parking or other <br />construction activity shall take place within the identified tree protection areas without <br />approval by the City." <br />• "Removal of dead, diseased, or hazardous trees shall be allowed with documentation <br />from a certified arborist as to the condition of the tree and the need for removal. <br />Documentation must be provided to the City for review and approval prior to tree <br />removal activity." <br />• "In the event a preservation tree must be removed, the justification of the removal <br />must be documented by a certified arborist. Documentation must be provided to the <br />City for review and approval prior to tree removal activity. The tree shall be replaced at <br />a ratio of two (2) trees for.each one (1) tree removed. Replacement trees shall be <br />native species, with a minimum caliper of 2" for deciduous canopy trees and a . <br />minimum height of Y for coniferous or evergreen trees. Planting, watering and general <br />maintenance of replacement trees shall be conducted by the lot owner in a manner <br />that ensures their establishment and long-term survival." <br />Staff Report <br />. <br />(PDT 10-2 & CU 11-1) June 2011 10 <br />HO Agenda - Page 1 <br />
