An intensive design effort was made to save as many trees on the site as possible. Through creative design and grading many of the trees were able to be preserved. Eight of the trees that are proposed for removal are (6) Siberian Elm, volunteer trees that most likely germinated naturally on the property. These trees are in fair to fair minus condition. Two of the trees are a Juniper and Linden tree that are also in fair minus condition. An additional two trees along Maple Street are being removed per the City’s direction due to the poor condition of the trees. Two Honey Locust trees identified as trees #4 and #6 on the attached Tree Inventory Exhibit, are situated within the middle of the proposed pedestrian walk along Cherry Street. Additionally, these trees are affected by existing soils that are required to be excavated for the building foundation. The over-excavation of the soil for the building encroaches into the critical root zone of both trees. Therefore, the impact to these trees will result in the trees mortality. Additionally, if the building were to be moved to accommodate the trees, it would have to move approximately 10.5’ to the south, away from the critical root zone. A total of 29 total units over 4 floors (10% of total units) would be affected. This will have an extremely negative economic impact on the project. Effectively resulting in the project being economically unfeasible. The trees will be mitigated with 4.5 as required by the City Forester and Fort Collins Municipal Code. Please refer to attached tree exhibits that correspond to this list. Exhibit A - Tree Inventory Exhibit and Exhibit B - illustrates the conditions affecting trees #4 and #6. 1. Siberian Elm – Remove, Mitigation Required: 0, fair condition (#1 per tree inventory plan) (8.5”) This tree is in poor conflicts with the proposed building, as well as grading and construction activities. 2. Volunteer Elm - Remove, Mitigation Required: 0, fair minus condition (#2 per tree inventory plan) (3-stem) This tree conflicts with the proposed building, as well as grading and construction activities. 3. Siberian Elm – Remove, Mitigation Required: 0, fair condition (#3 per tree inventory plan) (6”) This tree conflicts with the proposed building, as well as grading and construction activities. 4. Honey locust – Remove, Mitigation Required: 2.5 Trees, fair minus condition (#4 per tree inventory plan) (17”) (2.5) • Due to poor soils located on the property, an over-excavation of soils is required and will impact the critical root zone of the tree. Please refer to Exhibit B attached. • Excessive pruning will also be required to prune branches that are encroaching into the pedestrian walk and the building resulting in further impacts to the tree. 5. Honey locust – Remove, Mitigation Required: 2.5 Trees, fair condition (#5 per tree inventory plan) (17”) This tree conflicts with the proposed building and will be removed. 6. Honey locust - Remove, Mitigation Required: 2 Trees, fair condition (#6 per tree inventory plan) (13”) • Due to poor soils located on the property, an over-excavation of soils is required and will impact the critical root zone of the tree. Please refer to Exhibit B attached. • Excessive pruning will also be required to prune branches that are encroaching into the pedestrian walk and the building resulting in further impacts to the tree. 7. Honey Locust - Retain, good condition (#7 per tree inventory plan) (12”) The tree/lawn has been widened and the sidewalk adjusted to preserve this tree. 8. Linden - Remove, Mitigation Required: 1 Tree, fair minus condition (#8 per tree inventory plan) (9”) This tree conflicts with the proposed building, as well as grading and construction activities. 9. Honey Locust - Retain, fair condition (#9 per tree inventory plan) (9.5”) The tree/lawn has been widened and the sidewalk adjusted to preserve this tree. 10. Siberian Elm - Remove, Mitigation Required: 0, fair minus condition (#10 per tree inventory plan) (6”) This tree conflicts with the proposed building, as well as grading and construction activities. 11. Honey Locust - Retain, good condition (#11 per tree inventory plan) (9.5”) The tree/lawn has been widened and the sidewalk adjusted to preserve this tree. 12. Siberian Elm – Remove, Mitigation Required: 0, fair minus condition (#12 per tree inventory plan) (2”) This tree conflicts with the proposed building, as well as grading and construction activities 13. Honey locust - Retain, good condition (#13 per tree inventory plan) (6”) This tree is proposed to be preserved. 14. Honey locust - Retain, good condition (#14 per tree inventory plan) (8”) The walk and proposed retaining wall have been designed to provide additional room for this tree. The new design provides 10’ on either side of the tree trunk within an open planter that will improve the long-term viability of the tree. The current condition only provides a 4’x4’ tree grate surrounded by concrete. 15. Honey locust - Retain, good condition (#15 per tree inventory plan) (7.5”) The walk and proposed retaining wall have been designed to provide additional room for this tree. The new design actually provides 10’ on either side of the tree trunk within an open planter that will improve the long-term viability of the tree. The current condition only provides a 4’x4’ tree grate surrounded by concrete. 16. Honey locust - Retain, good condition (#16 per tree inventory plan) (8”) The walk and proposed retaining wall have been designed to provide additional room for this tree. The new design actually provides 10’ on either side of the tree trunk within an open planter that will improve the long-term viability of the tree. The current condition only provides a 4’x4’ tree grate surrounded by concrete. 17. Honey locust – Retain, fair minus condition (#17 per tree inventory plan) (17.5”) The walk adjacent to this tree has been designed to curve around the tree to provide additional room for the tree. 18. Honey locust – Remove, Mitigation Required: 3, fair condition (#18 per tree inventory plan) (22”) Per redline comments from round 1 of review, Forestry has permitted the removal of this tree due to the poor condition of this tree. 19. Honey locust – Remove, Mitigation Required: 2, poor condition (#19 per tree inventory plan) (16”) Per redline comments from round 1 of review, Forestry has permitted the removal of this tree due to the poor condition of the tree. 20. Juniper – Remove, Mitigation Required: 0, fair minus condition (#20 per tree inventory plan) (5.5”) This tree conflict with the proposed building, as well as grading and construction activities. Per the City Forester, no mitigation trees are required. 21. Siberian Elm – Remove, Mitigation Required: 0, poor condition (#21 per tree inventory plan) (12”) This tree will be a conflict with the proposed building, as well as grading and construction activities. Per the City Forester, no mitigation trees are required.
