E. DISCUSSION: • The tree preservation plan, date stamped by the city on April 20, 2017, shows the removal of one hundred eighty-four (184) trees located throughout the development. Most of the trees to be removed are trees that encroach upon the buildable lots, are located within the development infrastructure areas, are dead or diseased. A total of 1,551 caliper inches are proposed to be removed from the site which is equal to seven hundred seventy-six (776) two inch (2") caliper trees. A total of sixty-four (64) trees are required to be planted per 1,000 -square feet of common area. With the number of trees to be mitigated and the number of trees required to be planted per 1,000 -square feet, the applicant is required to provide eight hundred and forty (840) trees within this development.

The following two tables show the number and caliper inches of trees that are required to be mitigated when existing trees and off-site trees are removed from the overall calculation: Number of trees required to be mitigated Total trees required to be planted or mitigated Trees proposed to be planted off-site (on Alderwood Village and Rick' s River Ridge Estate) Trees proposed above the number of trees required per 1,000 -SF Unidentified trees to be retained on perimeter of buildable lots and common areas Trees required to be planted or mitigate Caliper inches of trees required to be mitigated Caliper inches to be planted or mitigated Caliper inches proposed to be planted off-site (on Alderwood Village and Rick's River Ridge Estates) Caliper inches existing or proposed Caliper inches of tree being retained but not located within the common area Caliper inches of tree unidentified (64 trees x 2" caliper) I Caliper inches required to be planted or mitigated *Note: 259 caliper inches = 130 trees The Design Review Board may determine that a minimum of seven hundred and forty-one (741) trees will need to be planted on site, or pursuant to Eagle City Code Section 8-2A-7(0), the applicant may elect to make a contribution to the tree fund for compensation for the removal of the trees at this time. The value is determined by calculating the purchase and planting cost using the average industry value of $350.00 for one (2 -inch) caliper tree. The total amount for seven hundred and forty-one (741) trees is $259,350.00. The Design Review Board may determine that the existing and proposed caliper inches of trees to be retained or planted on-site should be counted toward the caliper inches of tree being removed from the site. If the caliper inches are permitted to be used in the calculation, one hundred and thirty (130) two inch (2") caliper trees will need to be planted on-site, or pursuant to Eagle City Code Section 8-2A-7(0), the applicant may elect to make a contribution to the tree fund for compensation for the removal of the trees at this time. The total amount for one hundred thirty (130) trees is $45,500.00.
