B. The city shall require replacement of significant trees based on the diameter of the significant tree(s) removed. The number of trees to be replaced shall be determined using the following method:
1. Count the number of significant trees to be removed;
2. Measure the D.B.H. of those significant trees. The diameter of the trees shall be verified by the city;
3. Average the D.B.H. of those trees;
4. Multiply the number of significant trees removed by the number of tree units to determine the number of trees to be replaced. This number shall be identified as the total tree replacement number. (Ord. 2481 § 4, 2004)
