In instances involving a discretionary project, before a tree removal permit application can be approved by the director of public works, the approving body shall have made a finding that removal of the tree(s) is necessary for a reasonable use of the property, based upon the following criteria:

    A.    Whether or not the preservation of the tree(s) would unreasonably compromise the owner's development of the land under current zoning and development regulations;

    B.    The condition of the tree(s) with respect to disease or danger of falling;

    C.    The age of the tree(s), the relative scarcity or rarity of the species within the Grass Valley city limits, and the number of trees remaining in the immediate area;

    D.    The effect of such tree removal upon public health and safety, on property values and on the economic prosperity of the community, and on aesthetic values and the quality of life for residents;

    E.    The number of healthy trees that the given parcel of land can reasonably support;

    F.    The effect of tree removal on soil stability and erosion, and on increased runoff;

    G.    The potential for the tree to be a public nuisance or to interfere with utility service, and its proximity to existing structures;

    H.    Present and future potential for the tree(s) to shade and provide natural cooling or warming;

    I.    Whether or not any alternatives have been presented that would allow for the preservation of the tree, such as paving with a permeable substance, relocating proposed structures, driveways or sidewalks, the use of standard tree care practices, landscaping with the existing native vegetation, etc. (Ord. 455 § 2 (part), 1991)
