(a) Requirements for a tree preservation plan. Prior to any development, land clearing, <br />filling, or any other land alteration, as described in subsection (b) of this section, a tree <br />preservation plan shall be submitted to and approved by the city. The developer shall be <br />required to erect suitable protective barriers around all trees to be preserved and these <br />protective structures, where required, shall remain until such time as they are authorized <br />to be removed by the city or issuance of a final certificate of occupancy. <br />(b) Tree preservation plan. A tree preservation plan shall be submitted with preliminary plats <br />and /or site plans, drawn to the same scale as the other preliminary plat or site plan <br />submittals. The submitted tree preservation plan must include a buffer, if required, and <br />landscape plan for the project. <br />(1) Residential and commercial development plans shall be designed to preserve <br />natural vegetation areas as much as possible. Streets, parcels, structures and <br />parking areas shall be laid out to minimize the destruction of wooded areas or <br />outstanding tree specimens. Developers of land are encouraged to designate <br />wooded areas as park reserves. <br />(2) The city may require either the clustering of dwellings or alternate locations of <br />dwellings to preserve significant trees during the plat approval process. <br />(3) There shall be no movement, clearing, or storage of equipment within a <br />designated tree protection zone. The owner, developer, or agent shall not permit <br />the placement of construction materials, debris, soil deposits, or fill; nor cause or <br />permit disposal of waste materials such as paints, oils, solvents, asphalt, <br />concrete, mortar or any other harmful material within the dripline of any protected <br />tree area. <br />(c) Plan specifications content. The content of all tree preservation plans submitted shall, for <br />purposes of city staff review, include the following: <br />(1) Delineation of all areas located within a 100 -year floodplain; <br />(2) A tree survey overlay on the grading plan, which locates all significant trees <br />within the developable areas of the site, identifying both diameter and species. <br />Dead or diseased trees shall be included in the survey. All tree surveys for <br />subdivisions involving the construction of roads or drainage conveyances shall <br />be performed by an International Society of Arboriculture Certified Arborist or a <br />Society of American Foresters Certified Forester. For the purposes of this <br />division, significant trees shall include: <br />a. All species of oak that have a DBH of four inches or greater; <br />b. All evergreen species that have a DBH of four inches or greater; and <br />c. All other trees that have a DBH of eight inches or more; <br />(3) Existing soil conditions throughout the parcel; and <br />(4) Existing contour data for the entire property with vertical contour data consistent <br />with city standards for all areas to be disturbed by proposed tree removal <br />operations, extending for a distance of at least 50 feet beyond the limits of such <br />
