Tree #20, an 11” inch DBH aspen, was missing from the mitigation table and has been added. Also overlooked was an 11” inch Apple tree in the front South West corner of the property in the ROW which has been added to the mitigation table as tree #35. Please resubmit the “Tree Removal and Protection Plan L100” with red ‘X’s on the trees to be removed and colored polygons (you choose color) for the tree protection zones, and construction management plan. Because two additional Firs in the back yard and 2 Crabapples in the front yard are being retained there may need to be some changes to the planting plan for the 2 Spring Snow Crabapples proposed for the backyard and the Maple for the front yard. A replacement planting in the ROW of a Cottonwood tree 4” inches in DBH will be required for this project between trees #15 and #21. The Lilac stems in the ROW behind tree #14 shall be left undisturbed. Airspade excavation will be required for the new driveway in the back on the east side next to the large Lodgepole pine, tree #31. If I understand the design of the brick privacy wall correctly there are no footers but some excavation for the concrete ‘posts’. The later will need to be sited outside the driplines of the trees around the perimeter (#31, #29, #27, #25, #23, #22). Footers will not be allowed due to the conflict with trees being retained. Airspade excavation will be required. If placement of the posts is in conflict, complete redesign of the privacy wall will be required. Please expand on the proposed design. Walkway alignments and patio configurations may need to be reconsidered if they encroach on the driplines of trees being retained.   I will be out of town through Friday February 23. Dave Radeck may be able to answer questions in the interim.   Kind regards,   Ian Gray Aspen City Forester (970) 429­2031 CTSP, TRAQ, Grad. Cert. Urban Forestry ISA Board Certified Master Arborist #WE­6170BM   DENVER CARBONDALE DURANGO BOZEMAN WWW.DHMDESIGN.COM 311 Main Street, Suite 102 Carbondale, Colorado 81623 P: 970.963.6520 9/27/18 Comments received from: Ian Gray, City Forester 1. Tree #19 was incorrectly identified and is a Lodgepole Pine. a. DHM response: Acknowledged. Please see updated tree removal plan for correction. 2. Tree #20, an 11” inch DBH aspen, was missing from the mitigation table and has been added. a. DHM response: Acknowledged. Please see updated tree removal plan for correction. 3. Also overlooked was an 11” inch Apple tree in the front South West corner of the property in the ROW which has been added to the mitigation table as tree #35. a. DHM response: Acknowledged. Please see updated tree removal plan for correction. 4. Please resubmit the “Tree Removal and Protection Plan L100” with red ‘X’s on the trees to be removed and colored polygons (you choose color) for the tree protection zones, and construction management plan. a. DHM response: Acknowledged. Please see updated tree removal diagram sheet with red X’s and tree protection zones. 5. Because two additional Firs in the back yard and 2 Crabapples in the front yard are being retained there may need to be some changes to the planting plan for the 2 Spring Snow Crabapples proposed for the backyard and the Maple for the front yard. a. DHM response: Acknowledged. Please see updated planting plan for change. 6. A replacement planting in the ROW of a Cottonwood tree 4” inches in DBH will be required for this project between trees #15 and #21. a. DHM response: 4” cottonwood tree included in planting plan in location per City Forester. 7. The Lilac stems in the ROW behind tree #14 shall be left undisturbed. a. DHM response: Acknowledged. Updated tree removal and protection sheet shows the lilac clump as protected. 8. Airspade excavation will be required for the new driveway in the back on the east side next to the large Lodgepole pine, tree #31. a. DHM response: Acknowledged. Updated in notes, sheet L100. 9. If I understand the design of the brick privacy wall correctly there are no footers but some excavation for the concrete ‘posts’. The later will need to be sited outside the driplines of the trees around the perimeter (#31, #29, #27, #25, #23, #22). Footers will not be allowed due to the conflict with trees being retained. Airspade excavation will be required. If placement of the posts is in conflict, complete redesign of the privacy wall will be required. Please expand on the proposed design. a. DHM response: a brick privacy wall is no longer being proposed. 10. Walkway alignments and patio configurations may need to be reconsidered if they encroach on the driplines of trees being retained. a. DHM response: Acknowledged. Please refer to updated site materials plan.
