Summary

The City of Bloomington's Unified Development Ordinance lists Tree-of-Heaven (Ailanthus altissima) as a Prohibited Invasive Tree on Table 04-18. Any landscaping installed under a reviewed site plan, subdivision plat or other development approval in the City of Bloomington cannot use Tree-of-Heaven, and existing Tree-of-Heaven plantings do not count toward the landscaping the Unified Development Ordinance requires on a site.

(e)Prohibited Plant Species. Species identified in Table 04-18 (Prohibited Plant Species) are considered unacceptable and shall not be planted because of invasive characteristics, weak wood, and/or abundant litter. Table 04-18.

Full Breakdown

080(e) (Prohibited Plant Species). The table sits inside the landscaping chapter that governs every site plan, subdivision plat, buffer yard and parking lot planting plan the City of Bloomington's Planning and Transportation Department reviews. 080(c)(2)(C) backs the table with a general rule: any species identified as invasive, detrimental or noxious shall not be planted under any circumstances and, if it appears on a site anyway, will not be credited toward the canopy tree, shrub or ground-cover counts a project must meet. Tree-of-Heaven carries the caret symbol on Table 04-18 tying it to the Indiana terrestrial plant rule at 312 IAC 18-3-25, so a developer cannot argue state silence excuses the planting; both the state administrative rule and the City's own ordinance flag the species.

080(e) cites as its rationale. Because the ban lives in the development-review chapter rather than the nuisance or garbage-and-weeds title, it reaches new landscaping installed with a permit, plat or site plan rather than a homeowner's existing yard trees; Bloomington does not use this section to compel removal of a mature Tree-of-Heaven that predates a development application. 080(c)(1)(F) withholds a final occupancy recommendation until the approved landscaping, drawn only from permitted stock, is installed and inspected.

Violations & Fines

A landscape plan that specifies Tree-of-Heaven will be rejected at plan review by the Planning and Transportation Department, and any Tree-of-Heaven already on a development site is not counted toward the tree, shrub or ground-cover totals a project must satisfy under Section 20.04.080(c)(2)(C). Section 20.04.080(c)(1)(F) lets the City withhold the final occupancy recommendation until the required, permitted landscaping is installed and inspected, so a developer who ignores Table 04-18 risks a stalled certificate of occupancy rather than a direct fine.

Frequently Asked Questions

Can I plant a Tree-of-Heaven in my Bloomington yard?
No. Table 04-18 of the Unified Development Ordinance lists Tree-of-Heaven (Ailanthus altissima) as a Prohibited Invasive Tree under Section 20.04.080(e), and Section 20.04.080(c)(2)(C) says species on that list shall not be planted under any circumstances anywhere a landscape plan is reviewed by the City of Bloomington Planning and Transportation Department.
Does the City require me to remove a Tree-of-Heaven I already have?
The prohibition in Section 20.04.080 governs new landscaping submitted with a site plan, plat or permit application; it does not, on its own text, order removal of a Tree-of-Heaven that already exists on a property outside a pending development review in the City of Bloomington.
Why is Tree-of-Heaven banned from new landscaping?
Section 20.04.080(e) says species on Table 04-18 are barred because of invasive characteristics, weak wood, and abundant litter. Tree-of-Heaven also carries the caret symbol tying it to the Indiana terrestrial plant rule at 312 IAC 18-3-25, so state regulators flag the same species the Bloomington Common Council listed in its own code.
