c. The planting of trees for mitigation on residential projects shall be in addition to any other landscape <br />requirements of the City. <br />d. All trees, with the exception of ornamental trees, planted as landscaping on commercial or mixed -use <br />projects may be counted towards tree replacement requirements. <br />8) Tree replacement calculations. Thirty (30) percent of the total diameter inches of significant trees on the site of <br />new construction, new development, or redevelopment may be removed without replacement. The applicant shall <br />plant all required replacement trees on the site of the propo sed new construction, new development, or <br />redevelopment. The following calculation procedure must be used to determine tree replacement requirements: <br />a. Tally the total number of diameter inches of all significant trees on the site. <br />b. A calculation must be provided which breaks out the number of inches removed for hardwood, <br />evergreen/deciduous, and common trees. The thirty (30) percent removal figure applies to each category <br />individually and trees are replaced according to the Tree Repl acement Schedule in subsection (c)(8) of <br />this section. <br />9) Tree replacement schedule. Tree removals over the allowable tree removal limit on the parcel or site of new <br />construction, new development, or redevelopment shall be replaced according to the following schedule: <br />a. Common tree species shall be replaced with new trees at a rate of one-fourth (1/4) the diameter inches <br />removed. <br />b. Coniferous/evergreen tree species shall be replaced with new coniferous or evergreen trees at a rate of <br />one-half (1/2) the diameter inches removed. Since coniferous species are often sold by height rather than <br />diameter inch, the following conversion formula can be used: Height of Replacement Coniferous Tree/2 <br />equals Diameter Inches of Credit. <br />c. Hardwood deciduous tree species shall be replaced with new hardwood deciduous trees at a rate of one - <br />half (1/2) the diameter inches removed. <br />d. Replacement tree size. Replacement trees must meet the minimum sizes listed in L ake Elmo Code <br />Section 105.12.480. <br />10) Species requirement. The City must approve all species used for tree replacement. Ornamental trees are not <br />acceptable for use as replacement trees. Where ten (10) or more replacement trees are required, not more than thirty <br />(30) percent of the replacement trees shall be of the same species of tree. The planting of native species is <br />encouraged, and hardiness and salt tolerance of the plants should be considered where applicable. <br />11) Warranty requirement. Any replacement tree which is not alive or healthy, as determined by the City, or which <br />subsequently dies within two (2) years after the date of the initial landscape inspection and acceptance by the City <br />or of the project closure, whichever occurs later shall be removed by the applicant and replaced with a new healthy <br />tree meeting the same minimum size requirement within eight (8) months of removal. <br />10) 11) Protective measures. The Tree Preservation Plan requires the following measures to be utilized to protect <br />significant trees planned for preservation: <br />a. Before any grading or construction activity, the applicant shall install snow fencing or polyethylene <br />laminate safety netting at the drip line or at the perimeter of the critical root zone, whichever is greater, of <br />significant trees, specimen trees and significant woodlands to be preserved. No grade change, <br />construction activity, parking, or storage of materials shall occur within this fenced in area. <br />1. See Minnesota Department of Transportation Standard Plan 5 -297.301 and Minnesota Department <br />of Transportation Specification Section 2572 for specific requirements related to tree protection <br />and restoration. <br /> <br />b. Measures to be taken so that oak trees are not wounded, trimmed, pruned, or damaged in any way (root, <br />bark, branches, etc.) between the dates of March 15 and October 31. Measures to be taken to ensure that <br />any oak trees pruned or trimmed have any cut areas sealed with an appropriate nontoxic tree wound <br />sealant. <br />c. Prevention of change in soil chemistry due to concrete washout and leakage or spillage of toxic materials, <br />such as fuels or paints. <br />d. Removal of any nuisance or dead trees located in areas to be preserved. <br />e. Installation of erosion control methods. <br /> <br />12) Additional protective measures. The City encourages applicants to use the following tree protection measures to <br />protect the root zones and to prevent damage to significant and specimen trees that the applicant intends to preserve; <br /> <br />a. Installation of retaining walls or tree wells to preserve trees. <br />
