A.    In those instances where there is a nondiscretionary project involved prior to the issuance of a tree removal permit, the director of public works shall ascertain whether or not the tree(s) cannot or should not be retained. Within fourteen days of receipt of the application, the director shall inspect the premises and the tree or trees, and shall issue a proposed decision determining which, if any, trees may be destroyed, moved or removed and setting forth the conditions to be imposed. However, failure to act within fourteen days shall not constitute approval.

    B.    The determination of the director of public works in granting or denying a permit shall be considered upon the following criteria:

    1.    The condition of the tree with respect to disease, general health, damage, danger of falling, threat to nearby structures and whether or not the tree acts as a host of an organism which is parasitic to another species of tree which is in danger of being exterminated by the parasite. A certification from a certified arborist stating the tree(s) is (are) diseased or in danger of falling if such reason is given for removal may be required of the applicant by the director of public works.

    2.    The approximate age of the tree compared with the average life span for that species;

    3.    The relative scarcity or rarity of the species within the Grass Valley city limits;

    4.    Age of the tree with regard to whether or not removal of the tree would encourage healthier, more vigorous growth of younger, similar trees in the area;  

    5.    The number of existing trees in the area and the effect of the tree removal upon public health, safety, prosperity, beauty and general welfare of the area;   

    6.    The effect of tree removal on soil stability/erosion, particularly near watercourses or on steep slopes;   

    7.    The potential for the tree to be a public nuisance, or interfere with overhead or underground utility service or street or sidewalk improvements, as well as its proximity to existing structures;

     8.    Present and future shade potential with regard to solar heating and cooling;      

    9.    Whether or not there are any alternatives that would allow for the preservation of the tree; and

    10.    Any other information the director of public works finds pertinent to the decision, including, if necessary, information obtained at a public hearing. (Ord. 455 § 2 (part), 1991)
