Case No. Attachment C ZA17-100 Page 2 Tree Conservation/Landscape Review Keith Martin Landscape Administrator Phone: (817) 748-8229 E-mail: kmartin@ci.southlake.tx.us TREE CONSERVATION COMMENT: 1. The color Tree Conservation Plan proposes to mitigate 33” caliper inches of existing tree to be removed by planting 9 – 4” caliper trees. As long as the proposed tree removal and preservation complies with the Existing Tree Cover Preservation Requirements outlined within the Tree Preservation Ordinance, tree removal mitigation would not necessarily be required. There is no information provided on which trees are specifically being removed and mitigated. Please clarify. 2. Significant topography grade changes are proposed in the east and south landscape areas where existing trees are proposed to be preserved. Please ensure that the proposed grading does not conflict with existing trees proposed to be preserved. A protected tree shall be considered to be altered if one or more of the following occurs: more than twenty-five percent (25%) of the critical root zone is adversely affected, more than twenty-five percent (25%) of its canopy is removed, or the tree is disfigured to the extent a reasonable person would conclude the tree will not survive. * The proposed preservation of existing canopy cover complies with the Existing Tree Cover Preservation Requirements of the Tree Preservation Ordinance. The existing tree cover is 76% and a minimum of 40% of the existing tree cover is proposed to be preserved. The applicant is proposing to preserve 47% of the existing tree cover. * Except as provided by subsection 7.2.b. of the Tree Preservation Ordinance, a Tree Conservation Analysis or Tree Conservation Plan shall be approved if it will preserve existing tree cover in accordance with the percentage requirements established by Table 2.0. If the property has previously received a tree permit related to development, the percentage of existing tree cover at the time the first such permit was issued shall be used to calculate the minimum existing tree cover that must be preserved under this section. Table 2.0 – Existing Tree Cover Preservation Requirements Percentage of existing tree cover on the entire site Minimum percentage of the existing tree cover to be preserved* 0% – 20% 70% 20.1 – 40% 60% 40.1% - 60% 50% 60.1% - 80% 40% 80.1% - 100% 30% *The minimum percentage of existing tree cover to be preserved shall exclude any area in public rights - of-way as approved by City Council. * Please be aware that all existing trees shown to be preserved on the City Council approved Tree Conservation Plan must be preserved and protected during all phases and construction of the development. Alteration or removal of any of the existing trees shown to be preserved on the approved Tree Conservation Plan is a violation of the Tree Preservation Ordinance and the zoning as approved by the Southlake City Council. Please ensure that the layout of all Case No. Attachment C ZA17-100 Page 3 structures, easements, utilities, structures grading, and any other structure proposed to be constructed do not conflict with existing trees intended to be preserved. INTERIOR LANDSCAPE AND BUFFERYARDS COMMENTS: 1. The color Landscape Plan design does not match the black and white Landscape Plan design. There is a Red Bud shown on the south east bufferyard that is not shown on the black and white Landscape Plan. 2. Label and identify all required and provided bufferyards on the Site Plan. 3. Clearly delineate which existing trees are being used to provide existing tree credits for required interior landscaping and bufferyard landscaping. 4. Existing tree credits are proposed to be taken for existing trees preserved within the interior landscape and bufferyard areas. Existing tree credits shall only be granted if the tree/s are in healthy condition and all requirements of the Tree Preservation Ordinance have been met as determined at the time of inspection for a Permanent Certificate of Occupancy. * Indicates informational comment. # Indicates required items comment.
