6 <br /> <br />a. In any new development, redevelopment, new construction area, or grading project <br />where the allowable tree removal is exceeded, the applicant shall mitigate the tree loss by <br />planting replacement trees in appropriate areas within the development in accordance <br />with the Ttree Rreplacement Sschedule. <br />b. The form of mitigation to be provided by the applicant shall be determined by the City. <br />c. The planting of trees for mitigation on residential projects shall be in addition to any <br />other landscape requirements of the City. <br />d. All trees, with the exception of ornamental trees, planted as landscaping on commercial <br />or mixed-use projects may be counted towards tree replacement requirements. <br />8) Tree replacement calculations. Thirty (30) percent of the total diameter inches of significant trees <br />on the site of new construction, new development, or redevelopment may be removed without <br />replacement. The applicant shall plant all required replacement trees on the site of the proposed <br />new construction, new development, or redevelopment. The following calculation procedure must <br />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 <br />hardwood, evergreen/deciduous, and common trees. The thirty (30) percent removal <br />figure applies to each category individually and trees are replaced according to the Tree <br />Replacement Schedule in subsection (c)(8) of this section. <br />9) Tree replacement schedule. Tree removals over the allowable tree removal limit on the parcel or <br />site of new construction, new development, or redevelopment shall be replaced according to the <br />following schedule: <br />a. Common tree species shall be replaced with new trees at a rate of one-fourth (1/4) the <br />diameter inches removed. <br />b. Coniferous/evergreen tree species shall be replaced with new coniferous or evergreen <br />trees at a rate of one-half (1/2) the diameter inches removed. Since coniferous species are <br />often sold by height rather than diameter inch, the following conversion formula can be <br />used: Height of Replacement Coniferous Tree/2 equals Diameter Inches of Credit. <br />c. Hardwood deciduous tree species shall be replaced with new hardwood deciduous trees <br />at a rate of one-half (1/2) the diameter inches removed. <br />d. Replacement tree size. Replacement trees must meet the minimum sizes listed in Lake <br />Elmo Code Section 105.12.480. <br />10) Species requirement. The City must approve all species used for tree replacement. Ornamental <br />trees are not acceptable for use as replacement trees. Where ten (10) or more replacement trees are <br />required, not more than thirty (30) percent of the replacement trees shall be of the same species of <br />tree. The planting of native species is encouraged, and hardiness and salt tolerance of the plants <br />should be considered where applicable. <br />11) Warranty requirement. Any replacement tree which is not alive or healthy, as determined by the <br />City, or which subsequently dies within two (2) years after the date of the initial landscape <br />inspection and acceptance by the City or of the project closure, whichever occurs later shall be <br />removed by the applicant and replaced with a new healthy tree meeting the same minimum size <br />requirement within eight (8) months of removal. <br />10) 11) Protective measures. The Tree Preservation Plan requires the following measures to be utilized <br />to protect significant trees planned for preservation: <br />a. Before any grading or construction activity, the applicant shall install snow fencing or <br />polyethylene laminate safety netting at the drip line or at the perimeter of the critical root <br />zone, whichever is greater, of significant trees, specimen trees and significant woodlands <br />to be preserved. No grade change, construction activity, parking, or storage of materials <br />shall occur within this fenced in area. <br />1. See Minnesota Department of Transportation Standard Plan 5-297.301 and <br />Minnesota Department of Transportation Specification Section 2572 for specific <br />requirements related to tree protection and restoration. <br /> <br />b. Measures to be taken so that oak trees are not wounded, trimmed, pruned, or damaged in <br />any way (root, bark, branches, etc.) between the dates of March 15 and October 31.
