Florissant, MO Landscaping Rules: Tree Trimming (2026)

060, 'Minimum Clearances For Overhanging Trees and Shrubs Over Streets,' sets Florissant's basic vegetation-clearance standard for anything growing over a public street. Subsection A fixes the numbers: eight feet of clearance over sidewalks, eleven feet over ordinary streets, and fifteen feet over principal thoroughfares. Subsection B splits maintenance by ownership: trees and shrubs standing in a street, highway or street right-of-way are trimmed by the City itself, while trees on adjoining private property are the private owner's job. Subsection C gives the Director enforcement teeth: if a property owner bordering a street fails to trim trees or shrubs outside the right-of-way, the Director can order the owner, by written notice, to trim them within ten days.

060(A), rising to fifteen feet on principal thoroughfares. 050; the application must describe the number and species of trees, the work proposed and the method to be used, and permits become void if their terms are violated. 080: a fine of up to $1,000, up to three months in the City or County Jail, or both, with each day a violation continues counted as a separate offense.
