(3) Nonconformance. In case of nonconformance with the tree protection requirements set forth in specific construction practices in this section, the Director may issue a Stop Work Order until a mitigation plan has been reviewed and approved by the Director and shall be subject to a penalty, at a damage rate determined and periodically revised by the Director. Measurement of the damage shall be determined by the width of the wound measured at the widest point. Penalty shall be paid to the City and deposited to the Tree Fund.

(4) Tree damage or destruction. Should unauthorized work or nonconformance lead to the threat of tree damage or destruction, the Director shall issue a Stop Work Order until a mitigation plan has been reviewed and approved by the Director.

(5) Mitigation Plan. A mitigation plan shall include measures for protection of any remaining trees on the project site and include replacements for each tree removed at a replacement ratio set forth by Section 4-12.04.

(6) Performance security. Performance security, whether by security bond, cash deposit, or other security acceptable to the City, shall be required prior to issuance of a tree encroachment permit in order to assure protection of trees on the site. The amount of any said performance security shall be set at fifty (50%) percent of the value of the affected tree or trees, whichever is greater. Tree value shall be determined by using the Guide for Plant Appraisal (10th Edition or newer). The performance security shall be forfeited if, prior to final building permit inspection, the Director finds that the tree has suffered permanent damage. If no permanent damage has occurred, the performance security shall be returned two (2) years after the final building permit inspection has been completed. The applicant must submit a request for the two (2) year inspection and release of the security, in writing to the Director. If the tree(s) fail to survive, the applicant shall replace them. If the applicant fails to replace the tree(s), the performance security shall be forfeited. Funds collected through the forfeiture of performance security shall be deposited into the Tree Fund.

(f) Reporting. Any damage or injury to the roots, trunk, or branches of a protected tree(s) or City tree(s) shall be reported to the Director within twelve (12) hours by contacting the Director in writing with a detailed description of the damage and location of the tree.
