§ 10-24. Tree planting.

Commercial projects: A minimum of fifteen (15) trees per acre shall be either preserved or installed. At least five (5) of those trees shall be shade trees.

(1)

Trees shall be a minimum three-inch caliper.

(2)

Planting areas for trees shall be a minimum one hundred (100) square feet, with a minimum five-foot radius measured from the center of the trunk to the near edge of the planting area. These tree planting areas shall count toward the overall landscaping area requirement.

(3)

A minimum of five (5) trees per development site acre are required within parking lots of twenty-five (25) spaces or more. At least half of the trees shall be shade trees. Trees shall be reasonably distributed within the parking lot.

(4)

Planted or preserved trees that die which were fulfilling a development permit requirement, shall be replaced within ninety (90) days. This shall be on a tree-for-tree basis—not by inches removed caliper or DBH.

(5)

For purposes of substituting larger preserved trees for newly planted trees: The following table applies anywhere on the development site except that a minimum of five (5) trees per development-site acre are still required within parking lots of twenty-five (25) spaces or more.

Preserved Tree Size in DBH Inches	Reduction in Planted Tree Requirement
6" up to but not including 9"	One (1) less tree
9" up to but not including 12"	Two (2) less trees
12" up to but not including 15"	Three (3) less trees
15" up to but not including 18"	Four (4) less trees
18" and above	Must be preserved
