A. Applicability: Street trees aid in beautifying and shading the Village by providing consistent and appropriately spaced trees. The requirements of this section apply to existing and proposed parkway areas adjacent to new developments that require approval of site plan review (see section 10-3-2, "Site Plan Review", of this title) or planned unit development (see chapter 4, "Planned Unit Developments", of this title).
B. Street Tree Requirements:
1. Frequency: Street trees shall be installed at a minimum rate of one large shade tree per forty (40) linear feet. Trees shall be spaced on center, or at a rate that matches the existing tree spacing pattern on adjacent parkways, whichever results in a greater density of tree plantings. Spacing may be adjusted to ensure adequate room for streetlights and utilities, with prior written Zoning Administrator approval.
2. Tree Wells: Tree wells shall be utilized in locations where the sidewalk extends from the back of the curb to the lot line and there is no parkway present.
3. Drought And Salt Tolerance: All street trees proposed to be planted shall be drought- and salt-tolerant. Refer to the most recent Morton Arboretum Northern Illinois Tree Species List for preferred plant species. (Ord. 67-2018, 12-18-2018; amd. Ord. 74- 2019, 12-17-2019)
