(A) This chapter, as amended, does not apply to single-family, duplex and single-family attached lots after initial development and final inspection of the dwelling, nor to any expansion, addition or alteration to any existing single-family, duplex and single-family attached dwelling. This chapter, as amended, does not apply to the redevelopment of single-family, duplex or single-family attached dwellings on a lot previously used for a single-family, duplex and single-family attached dwelling. However, the development of any new nonresidential or multi-family structure on a lot previously used or zoned for a single-family, duplex and single-family attached dwelling residential use shall not be exempt from the requirements of this chapter as amended.
(B) Nothing herein contained shall require any change in the plans, construction or designated use of any parcel of property for which a permit for construction has been issued, at the effective date of this chapter or amendments hereto.
(C) During the period of an emergency, such as a tornado, storm, flood or other natural disaster, the requirements of this chapter may be waived as deemed necessary by the emergency management coordinator or other designee of the City Manager. In addition to rights granted by easement, utility service providers, lawfully within the right-of-way, may remove trees during the period of an emergency that are determined by the company to be a danger to public safety and welfare by interfering with utility service.
(D) In the pursuit of maintenance or installation of its facilities, utility service providers or their contractors, agents, successors and assigns shall have the right to trim or remove trees so as to prevent any part of the trees from becoming a danger to public health, safety and welfare by interfering with utility service. Any trimming or removal shall be done in a manner such that the aesthetics and health of the trees are not destroyed and shall be done under the supervision and direction of any city official to whom the duties have been or may be delegated.

(Ord. 2520, passed 6-6-00)
Sec. 155.06. Tree preservation and protection.
(A) No clear-cutting of land is allowed. Prior to construction or development on a site that contains one or more protected trees, a tree preservation plan must be approved by the city. If the site does not contain any protected trees, a letter, prepared by a registered surveyor, engineer, architect or landscape architect, shall be submitted to the city, which verifies that protected trees are not on the subject site.
(B) The application for a tree preservation plan shall be submitted on a form provided by the city and accompanied by a site plan that includes, but is not limited to the following:
(1) Delineation of site boundaries.
(2) Location of all existing or proposed structures; improvements such as streets, alleys and easements.
(3) A survey depicting the location and caliper of all protected trees to be preserved.
(C) Protected trees, which are not required to be removed or have been identified on the tree preservation plan to be preserved, must be protected under the following conditions:
(1) No materials intended for the use in construction or waste materials accumulated due to excavations or demolition shall be placed within the limits of the critical root zone.
(2) No equipment shall be cleaned or other foreign materials deposited or allowed to flow overland within the critical root zone of a protected tree. This includes without limitation, paint, oil, solvents, asphalt, concrete, mortar or similar materials.
(3) No signs, wires or other objects, other than those of a protective nature shall be attached to any protected tree. However, lighting of a decorative nature may be attached to a protected tree. The lighting shall be attached in a manner as not to damage the protected tree.
(4) No vehicular and or construction traffic or parking shall take place within the limits of the critical root zone of any protected tree other than on an existing paved surface. This restriction does not apply to access within the critical root zone for purposes of clearing underbrush, establishing the building pad and associated lot grading, vehicular traffic necessary for routine utility maintenance or emergency restoration of utility service or routine mowing operations.
(5) Grade changes shall be allowed within the limits of the critical root zone of any protected tree only upon approval by the city.
(6) No paving with asphalt, concrete or other impervious materials shall be placed within the critical root zone of a protected tree. However, paving may encroach up to five feet from the trunk upon approval by the city.
(7) In those situations where a protected tree is within 50 feet of a construction area, a protective fence, minimum of four feet in height, shall be erected and maintained outside of the critical root zone of each protected tree or tree group. The protective fencing shall be only required on the subject site if the critical root zone extends onto adjacent property. It is not the intent of this provision to prohibit the development of a site in accordance with division (C)(6) of this section.
(8) No person, directly or indirectly, shall prune, cut down, destroy, remove or move, or effectively destroy through damaging, any protected tree on city-owned property unless otherwise permitted by this chapter.
(D) The city shall have the right to plant, prune, and maintain any tree located on a right-of-way, easement, public park land or any other municipally-owned property as may be necessary to ensure public safety or to preserve or enhance the symmetry and beauty of the public properties. The city may remove or cause or order to be removed any tree or part of thereof, which is in an unsafe condition, or which, by reason of its nature, is injurious to sewers, electric power lines, gas lines, water lines or other public improvements.

The application for a tree removal permit shall be submitted on a form provided by the city. Permits may be issued with verification that the protected tree is damaged or diseased.
(B) The application for a tree removal permit shall be submitted in conjunction with the following:
(1) An application for a development permit to fill or grade property.
(2) An application for a preliminary plat, including the development of new internal streets, final plat, or an administrative plat, whichever is applicable for the initial phase in the platting process.

(F) Consideration for the approval of a tree removal permit shall be based upon the following guidelines:
(1) Whether the removal of the protected tree is permitted by section 155.05 of this chapter.
(2) Whether or not a reasonable accommodation or alternative solution can be made to accomplish the desired activity without the removal of the protected tree.
(3) The effect of the removal of the protected tree on erosion, soil moisture, retention, flow of surface waters, and drainage systems.
(4) The need for buffering of residential areas from the noise, glare, and the visual effects of nonresidential uses.
(5) Whether the removal of the protected tree affects the public health, safety or welfare of the city.
(6) Whether the application demonstrates the attempt to preserve existing trees on the site.

(2) The planting of the replacement trees within private open space.
(3) The payment of a fee into the tree restoration fund in the amount in accordance with a fee schedule provided by the city. The fee schedule shall be based on the average cost of the required replacement tree and the average cost of installation. The funds shall be used solely for the purpose of purchasing and installing trees on public rights-of-way, public park land or any other municipally-owned property.

The minimum landscape requirements of the landscape buffer shall be met in addition to this chapter when applicable.
(B) No protected tree shall be pruned in a manner which significantly disfigures the tree, or in a manner which would reasonably lead to the death of the tree. This section is not intended to require a tree removal permit for reasonable pruning performed or contracted to be performed by the owner of the tree.
