Landscaping Rules in Florissant, MO

If you live in Florissant or are thinking about moving there, landscaping rules are one of those things you probably won't think about until they affect you directly. Florissant has 4 specific rules on the books covering different aspects of landscaping rules, and some of them might surprise you.

Tree Trimming

Florissant requires eight feet of clearance over sidewalks and eleven feet over streets for overhanging tree and shrub branches, rising to fifteen feet on principal thoroughfares. The City trims trees standing within a street right-of-way itself, but owners of property bordering a street must trim their own overhanging branches under Code of Ordinances Section 230.060.

Key details: Sidewalk clearance: 8 feet minimum. Street clearance: 11 feet minimum. Principal thoroughfare clearance: 15 feet minimum. Owner notice period: 10 days to comply. Right-of-way planting height cap: 36 inches.

Failing to trim overhanging branches after a Director's written notice, or disturbing a public tree without a permit, is enforceable under Florissant's general penalty, Section 100.080: a fine of up to $1,000, up to three months in jail, or both, with each day of continued violation treated as a separate offense. The Director may also order City crews to trim the tree and assess the cost to the owner as a special assessment.

Composting

Florissant's Code of Ordinances doesn't regulate composting directly, but § 220.010 carves compost out of the definition of "garbage" entirely, as long as the pile doesn't create a nuisance or emit an obnoxious odor. Cross that line, though, and Chapters 213 and 220's nuisance and container rules both apply.

Key details: Compost bin permit: None required. Governing definition: § 220.010 GARBAGE. Condition of exemption: No nuisance, no obnoxious odor. If pile becomes a nuisance: Treated as garbage / nuisance under Ch. 213. Garbage container standard (if triggered): 5-95 gal, fly-proof lid.

There's no compost-specific fine because there's no compost-specific rule to break, only the underlying nuisance ordinances. A pile that draws flies, rats or complaints about odor loses its compost exemption under § 220.010, and the Building Commissioner can pursue it as a nuisance affecting health under § 213.010 or a public nuisance under § 213.030, with notice, an abatement order and the cost billed to the owner if it isn't fixed.

If you are coming from a city with tighter rules, you will find Florissant gives residents more flexibility on composting.

Weed Ordinances

Florissant caps weeds and grass at eight inches under City Code § 213.070. Anyone who lets weeds grow taller than eight inches on a lot they own, lease, occupy or control is guilty of a misdemeanor. The Director of Public Works can order a hired crew to cut the lot and bill the owner if written notice goes unanswered.

Key details: Height limit: 8 inches. Governing section: § 213.070. Notice period: 5 days after receipt (10 if mailed). Repeat-violation notice: None required same growing season. Interest on City cutting bill: 6% per year.

A first offense triggers written notice, not an immediate ticket: the code requires proof of the § 213.080/213.090 notice before prosecution begins. Ignore that notice and the Director of Public Works cuts the lot and bills the owner at actual cost plus 6% annual interest, recorded as a lien with the St. Louis County Recorder of Deeds if unpaid. A second violation in the same growing season skips the notice step entirely.

Tree Removal & Heritage Trees

Florissant requires a permit from the Director of Public Works before anyone trims, removes or otherwise disturbs a City-owned or street tree, under Code Section 230.040(A). Unauthorized damage or removal of a public tree is separately barred by Section 230.070.

Key details: Permit required for: Trimming/removing/disturbing a street or City-owned tree. Issued by: Director of Public Works. Unauthorized damage: Separately banned by §230.070. Construction buffer: No digging within 10 ft of public tree (§230.100). Penalty: Up to $1,000 fine and/or 3 months jail.

Trimming, cutting or removing a public tree without a Section 230.040(A) permit, or damaging one without Director authorization under Section 230.070, is punishable under the City's general penalty, Section 100.080: a fine of up to $1,000, up to three months in the City or County Jail, or both, and the Director can void an existing permit for a violated condition.

This is one of the stricter rules in Florissant's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.
