Full Breakdown

St. George City Code section 7-4-9 sets the city's intent to protect and enhance existing vegetation in public greenbelt areas established along floodways and waterways, an effort overseen by the shade tree and beautification board. Development landscape and vegetation plans affecting those areas go through the board's review process. Within that section, subsection C singles out tamarisk, noxious weeds, briars, and certain underbrush by name as undesirable vegetation that 'shall be discouraged' in preserving natural vegetation: soft language, not an outright ban. The clause applies only to public greenbelt/floodway/waterway areas, not to private landscaping citywide, and carries no planting permit or fine of its own.

Violations & Fines

The clause itself sets no fine or ban: it says undesirable vegetation 'shall be discouraged,' not prohibited. The chapter's general violations section covers unauthorized tree removal or damage, punishable as a Class B misdemeanor under section 7-4-13.

Frequently Asked Questions

Does St. George ban invasive plants like tamarisk on private property?
No. Section 7-4-9(C) only discourages tamarisk and other undesirable vegetation within public greenbelt areas along floodways and waterways: it doesn't regulate private landscaping citywide.
Is there a fine for tamarisk or noxious weeds under this section?
The code doesn't set one here. The greenbelt clause uses discouraging language rather than a prohibition, so no fine attaches specifically to undesirable vegetation.
