TREE PLANTING TEMPLATE - SPACING BETWEEN TREES <br /> Urban Forestry Program <br /> Eugene Public Works Department <br /> To find the distance needed from an existing tree or between new trees please <br /> use the following matrix and figure. The crown spreads for trees can be found <br /> either in the "Descriptions of Recommended Tree Species ", or in many tree <br /> books, or by asking the City's Urban Forester. The spacing between trees must <br /> be used in conjunction with the "Site Constraint" template and the "Other <br /> Restriction" template. In practice, the actual spacing will be greater due to <br /> the spacing requirements for "Site Constraints." <br /> TREE - A <br /> Crown Spread <br /> Distance Between Trees 40'+ 30' 20' <br /> m ' 40'+ 40' 35' 20' <br /> C1 <br /> W v ' 30' 35' 35' 20' <br /> w c <br /> cc 3 <br /> I ° 20' 20' 20' 20' <br /> U <br /> For example, two bigleaf maples (40'+ crown spread) would be spaced 40 feet <br /> apart. In addition, there is room to plant a narrow crown tree, such as a <br /> dogwood, with a 20 foot space between the maple and dogwood. <br /> ; 5 ; : --: 1 . =`'4 c i s ; = , A: (.r % . - 1' b'E t ^ f ' - -L fr > :' `il.

The <br /> power company will trim the trees to keep the limbs away from their lines and <br /> possible leave the tree unsightly. <br /> Do not plant large maturing trees at sites where the distance between the curb <br /> and sidewalk is less than 6 feet. <br /> Do not plant trees in ditches along the road. <br />
