A. The species of the street trees to be planted shall be chosen from the McMinnville Street Tree List, as approved by Resolution 2016-22, unless approval of another species is given by the McMinnville Landscape Review Committee. The Landscape Review Committee may periodically update the McMinnville Street Tree List as necessary to reflect current arborist practices and industry standards.

B. Street trees shall be a minimum of two inches in caliper measured at six inches above ground level. All trees shall be healthy grown nursery stock with a single straight trunk, a well developed leader with tops and roots characteristic of the species cultivar or variety. All trees must be free of insects, diseases, mechanical injury, and other objectionable features when planted.

C. Small or narrow stature trees (under 25 feet tall and less than 16 feet wide branching) should be spaced no greater than 20 feet apart; medium sized trees (25 feet to 40 feet tall, 16 feet to 35 feet wide branching) should be spaced no greater than 30 feet apart; and large trees (over 40 feet tall and more than 35 feet wide branching) should be spaced no greater than 40 feet apart. Within residential developments, street trees should be evenly spaced, with variations to the spacing permitted as approved by the city for specific site limitations and safety purposes. Within commercial and industrial development staggered, or irregular spacing is permitted, as may be approved by the McMinnville Landscape Review Committee. When planting replacement trees within the Downtown Tree Zone, consideration shall be given to the height of adjacent buildings.

D. When located adjacent to a local residential street or minor collector street, street trees shall be planted within a curbside landscape strip measuring a minimum of three feet in width. Street trees adjacent to major collector streets or arterial streets shall be placed a minimum of four feet from the back edge of the sidewalk. In no case shall a tree be planted closer than two and one-half (2 1/2) feet from the face of a curb. These standards may be superseded by design drawings and specifications as periodically developed and adopted by the city.

E. Street trees shall not be planted within 10 feet of fire hydrants, utility poles, sanitary sewer, storm sewer or water lines, or within 20 feet of street light standards or street intersections, or within five feet of a private driveway or alley. New utility poles shall not be located within five feet of an existing street tree. Variations to these distances may be granted by the public works director and as may be required to ensure adequate clear vision.

F. Existing street trees shall be retained unless approved by the planning director for removal during site development or in conjunction with a street construction project. Sidewalks of variable width and elevation may be utilized as approved by the planning director to save existing street trees. Any street tree removed through demolition or construction within the street right-of-way, or as approved by the city, shall be replaced within the street right-of-way at a location approved by the city with a tree, or trees, of similar value. As an alternative the property owner may be required to pay to the city an amount sufficient to fund the planting and establishment by the city of a tree of similar value. The value of the existing street tree to be removed shall be calculated using the methods set forth in the edition then in effect of the “Guide for Plant Appraisal” published by the International Society of Arboriculture Council of Tree Landscape Appraisers. The developer or applicant shall be responsible for the cost of the planting, maintenance and establishment of the replacement tree.

G. Sidewalk cuts in concrete for tree planting shall be a minimum of four feet by six feet, with the long dimension parallel to the curb, and if located within the Downtown Tree Zone shall follow the design drawing or updated design drawings and specifications as periodically developed and adopted by the city. (Ord. 5027 §2, 2017; Ord. 4816 §2, 2004; Ord. 4654-B §1, 1997).
