Any trees that are removed or damaged as a result of the approval of a Tree Removal Permit or under the provisions of subsection B.4 above shall be mitigated for on the same site as the proposed development, in addition to landscape requirements. In the event that mitigation is not feasible on the same site as the proposed development, an Applicant may request to donate trees, meeting the mitigation requirements of this section, to be planted at public parks, schools, or other approved public facilities throughout the City or provide a fee in lieu of payment which will be used to place trees at public parks, schools, or other approved public facilities throughout the City.

c.
Tree planting and care standards.
