(a) Stop work order. Whenever any work is being done contrary to the provisions of this division, the building official may order the work stopped by notice in writing served on any person engaged in the work or causing the work to be done. A person issued this notice shall stop work immediately until authorized by the building official to proceed with the work.
(b) Mitigation. The building official may require mitigation for the removal, or serious injury, of protected trees without a tree removal application or a building permit upon written notice of a violation of this division.
(1) Mitigation may include:
(A) replacement of nursery stock trees on the property based on a tree mitigation plan provided by the responsible party, if it is determined by the building official that it is practicable to plant trees on the tree removal property;
(B) other alternative methods of compliance in this article when approved by the building official; or
(C) a fee to be applied to the Reforestation Fund, with the amount determined in Section 51A-10.135.
(2) The responsible party must provide a tree survey or a forest stand delineation identifying all tree sizes and species, or tree canopy coverage, on the property.
(A) If the responsible party fails to provide the required information within 30 days of the notice of violation the building official may conduct a forest stand delineation using aerial imagery, field analysis, or other reasonable and pertinent information to review and identify the square footage of tree canopy coverage on the property.
(B) Required mitigation is calculated as follows:
(i) When tree size and species are identified in a verifiable survey provided by a consulting arborist and approved by the building official. Mitigation is required in accordance with Section 51A-10.134.
(ii) When protected trees have been removed with no measurable remaining evidence. Mitigation is required in accordance with Section 51A-10.134 as determined using the following calculation.
(aa) The tree canopy coverage area is estimated by measuring the tree canopy coverage area shown in an aerial image no older than three years before notice of violation.
(bb) The estimated tree canopy coverage area, in square feet, on the tree removal property is divided by 1,200 square feet to determine an estimated number of trees for the area.
(cc) The number of trees is multiplied by eight inches as the estimated average of trees to determine the inches of the trees to be replaced.
(iii) Reforestation fund.
(aa) The number of inches to be replaced for trees not located in a primary natural area is multiplied by the Class 2 base rate (0.7:1) to calculate reforestation fund value.
(bb) The number of inches to be replaced for trees located in a primary natural area is multiplied by the Class 1 base rate (1:1) to calculate reforestation fund value.
(3) Upon a finding by the building official that tree canopy coverage removal has occurred, the building official shall give written notification to the responsible party. Tree replacement or mitigation must be completed within 90 days of the date of the notification. (Ord. Nos. 22053; 25155; 30929)
