TREE PRESERVATION
(A) Purpose. The purpose of this chapter is to conserve and protect to the greatest extent possible the city's existing trees, wooded areas, and fence rows; to enhance and promote the community image; to enhance and preserve economic property values and the quality of life in the city; to aid in the alleviation of erosion, siltation, and other harmful effects of land disturbing activities; to aid in controlling the quantity and intensity of stormwater runoff; to alleviate air pollution and non-point source water pollution; to conserve energy; to protect and promote the use of existing vegetation as noise and visual buffers; to preserve the environmental and ecological benefit of trees on air pollution and carbon dioxide levels as well as dust filtration; to reduce energy consumption through the wind break and shade effects of trees when they are properly placed on a site; to preserve and enhance nesting areas for birds and other wildlife and to preserve movement corridors for wildlife; and to promote the public health, safety, and welfare through the preservation and replacement of trees while allowing for the reasonable development of lands in such a manner that implements the stated goals, objectives, policies and standards of the city.
(B) Applicability.
(1) This subchapter applies to trees which have a minimum six-inch diameter breast height (DBH), hereinafter known as protected trees, on all public and private properties, in all zoning districts. On lots containing no more than one detached single-family dwelling, § 153.146, "Tree Replacements," shall apply only to those areas of the single-family lot designated as a "No Build Zone/No Disturb Zone" and/or "Tree Preservation Zone" and to trees required as front yard trees in § 153.133, "Minimum Landscape Requirements." All other sections of this subchapter shall be applicable to single-family residential lots.
(2) This tree preservation subchapter shall not apply to sites which have previously approved final development plans, final plat, or a certificate of zoning compliance or other similar final approval by the city prior to the date this provision takes effect.

AGGREGATE DIAMETER. The combined diameter of a multiple trunk tree measured at breast height (See diameter breast height).
BUILDING ACTIVITY AREA. The area of a lot in which construction and building activities are to be limited and hence shall be the smallest possible area of a lot or parcel of land within which building activity may take place, including the entire area affected by building and grading activities related to the proposed construction, to be determined with maximum regard for existing trees.

For sites on which development activity is to occur on less than the entirety of the site, the city may provide that the tree survey exclude those portions of the site which it determines will not be affected by the development activities. The tree survey shall also include a listing of the species and condition of each tree;
(7) A report from a certified arborist if required by the city; and
