February 25, 2026 Granvia Preserve Memorandum 3 7. Once the landscape plan is revised based on tree replacement and other landscape requirements, minimum tree composition requirements must also be met. 8. If clearing and grubbing of existing trees, underbrush, and stumps is proposed along the northern property line as shown on sheet C100, there will be significant impacts to the character of existing homes. Provide a plan diagram showing proposed trees and existing buffer trees to remain, and a section cut from the existing properties north of the development down to the toe of the proposed slope showing that proposed landscaping will provide adequate visual mitigation where existing vegetation is proposed to be removed. 9. Notes on sheet L1.1 and L1.2 indicate that trees “shall not be not less than 1.5 inches in caliper measured at 54 inches above grade level.” Refer to table 6-1 in the code for minimum size requirements at planting and revise this note to match. Deciduous trees must be at least 2.5” caliper and ornamental trees must be at least 2”. 10. Replace the tree planting details on sheet L1.1 with the city standard tree planting details. GENERAL NOTES: • I have concerns about the intense grading along the northern border of the development, given its proximity to existing backyards of single family homes and the removal of valuable screening that existing trees provide. Our code says, “All applicants are encouraged to preserve all healthy trees of significant value even if the trees do not meet the size requirements to be considered significant trees.” Unnecessary removal of screening buffers has caused significant issues in past projects and we would like to avoid this moving forward. • If the number of actual required mitigation trees is anywhere near the quantity (1,370) shown on the current plans, this may be an indication that the applicant’s site layout disturbs too much high value woodland and is removing more significant trees that they can feasibly replace. If, after properly calculating required replacement trees, the applicant finds this is the case, they should revise the scope of their proposed development to reduce impacts, specifically in the hardwood forest on the north side of the central wetland complex. This would also ensure adequate wetland buffers are maintained here. RECOMMENDATION: The landscape and tree preservation plans must be revised and resubmitted to address the items in this memo.
