Attachment 2: Landscaping and Tree Preservation Standards Page 14 12. Tree Survey: a. A tree survey is required for all property that contains a deciduous tree greater than 6" dbh or an evergreen tree greater than 12' tall. At the City's discretion, the tree survey requirement may be waived under the following circumstances: 1) Deciduous trees greater than 6" dbh or evergreen trees greater than 12' tall will not be removed or are likely to be impacted by construction. 2) Deciduous trees greater than 6" dbh or evergreen trees greater than 12' tall will only be removed within the basic use area and the basic use area is not an ESA. b. The tree survey shall be the basis for the tree protection plan, tree mitigation requirements, and the use of existing trees to fulfill landscape requirements. c. The tree survey must include tree species, size, location, dripline, canopy line and tree condition for all deciduous trees over 6" dbh, all evergreen trees greater than 12' tall, or the location of tree stands proposed for protection, including trees on adjacent properties where the root zone extends onto the development property. 13. Tree Protection Plan: a. A tree protection plan shall be required for all soil disturbance activities where tree preservation and mitigation requirements apply in accordance with Q.11.a. A tree protection plan shows how protection and mitigation requirements will be met and how preserved trees will be protected during construction and other potentially harmful activities. b. The tree protection plan shall be based on the tree survey. c. If a tree survey shows that no desirable deciduous trees over 6" dbh or evergreen trees greater than 12' in height on the development property or adjacent properties are near the construction area, the City may waive the tree protection plan requirement. d. A tree protection plan shall include: size (dbh), species, condition, location, and root projection zone (5' out from the dripline) for all deciduous trees over 6' dbh or evergreen trees greater than 12' tall to be preserved or the combined root protection zone of all stands of trees designated for protection, whichever is applicable. The plan shall show location and type of tree protection fence, staging areas, and concrete washout areas. Fencing shall be installed and inspected by the City prior to soil disturbance. The plan shall show directional felling if necessary to avoid damage to adjacent trees. e. Trees to be preserved shall be tagged in the field and keyed to the tree protection plan. The City may inspect the trees to verify compliance with the protection plan at any time during construction. f. The tree protection plan should not conflict with natural resource management plan required for environmentally sensitive areas. See Section 2, Subd. 6.E.2.b. See the Stormwater Ordinance for other construction related requirements. g. 14. Individual Lot Tree Preservation Plan: To be determined. • • •
