Port St. Lucie's Landscaping Rules: The Rules That Matter

Every city handles landscaping rules a little differently. In Port St. Lucie, Florida, there are 7 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Native Plants

Port St. Lucie's landscape code sets native-species quotas for regulated sites: at least 50% of required trees and 25% of shrubs must be native. Single-family lots instead owe a set number of trees by lot size.

Key details: Code Section: §§ 154.03, 154.04. Native trees: At least 50% of required trees. Native shrubs: At least 25% of all shrubs. Invasive species: Category 1 species cannot count. Single-family lots: Trees required by lot size.

Section 154.07 puts enforcement with the Zoning Administrator and treats landscape violations like Zoning Code violations, so Section 158.999(A) applies the Section 10.99 fines, each day a separate offense.

Weed Ordinances

On improved property in Port St. Lucie, owners must keep grass and weeds from exceeding 12 inches in length, and must also mow and clear the swale between the pavement and their property line.

Key details: Governing section: Sec. 41.08(b). Maximum grass height: 12 inches. Applies to: Improved property, a lot with a structure. Swale duty: Sec. 41.08(g)(2), mow and clear. Nuisance threshold: Two feet, under Sec. 40.05.

Code compliance issues a notice first. Untended grass over two feet becomes a nuisance the city may abate under Sec. 40.20, with the cost assessed against the property, and the special magistrate may fine up to $1,000 per day.

Tree Removal & Heritage Trees

You need a tree removal permit before cutting down, substantially altering, relocating or damaging a protected tree in Port St. Lucie: any tree of 12 inches D.B.H. or greater, or any native palm with at least ten feet of clear trunk.

Key details: Code Section: Secs. 154.14 through 154.17. Protected tree: 12 inches DBH or greater. Native palm: Minimum clear trunk of ten feet. Mitigation: One inch DBH per inch removed. No-permit penalty: Up to triple replacement, double fee.

Under section 154.17(A) trees removed without a permit bring replacement of up to three times the amount plus twice the normal application fee. Each tree is a separate violation, and no certificate of occupancy issues until you comply.

Tree Trimming

Routine trimming and pruning that is not meant to kill the plant needs no permit in Port St. Lucie. Substantially altering or damaging a protected tree does: 12 inches D.B.H. or greater, or a native palm with ten feet of clear trunk.

Key details: Code Section: Sec. 154.14(A), exception 10. Routine trimming: No permit required. Protected tree: 12 inches DBH or greater. Native palm: Minimum clear trunk of ten feet. Unimproved lots: Trim branches within four feet of dwelling.

Section 154.17(A) treats each protected tree cut in violation as a separate offense, with replacement of up to three times the amount for every offense and twice the normal tree removal application fee.

Water Restrictions

Port St. Lucie adopts the South Florida Water Management District's year-round landscape irrigation rules by reference in section 65.07. The city writes the daily no-water window into its own code but leaves the day-of-week schedule to the District.

Key details: Adopted rule: SFWMD Chapter 40E-24.201(1)-(6), F.A.C.. Daily no-water window: 10:00 a.m. to 4:00 p.m.. New landscaping, first 30 days: All days except Friday. Existing landscaping days: Set by Chapter 40E-24.201, F.A.C.. Variance limit: No zone more than three days weekly.

Section 65.08 makes each day in violation a separate offense and allows no more than one written warning. The city may enforce through Chapter 37, where fines reach $1,000.00 per day for a first violation.

Artificial Turf

Port St. Lucie's landscaping code will not let artificial turf, or any synthetic tree, shrub, ground cover or vine, satisfy a site's required plant landscaping. Section 154.04(H) bars substituting synthetic material for the live plant standards the rest of Chapter 154 sets for landscaping required citywide under site plan approval.

Key details: Core rule: No synthetic turf in place of required plants. Applies to: Required landscaping citywide. Sod cap: Max 50% of site landscaping. Enforcer: City planning and code compliance.

A landscape plan or installed yard that swaps artificial turf for required trees, shrubs, ground cover or lawn grass fails Chapter 154's material standards, so the Site Plan Review Committee will reject it before approval, and an already-built noncompliant landscape is enforced through § 154.07's city planning and code compliance process.

This is not one of those rules that cities tend to ignore. Port St. Lucie actively enforces its artificial turf requirements.

Composting

Port St. Lucie treats a backyard compost pile as recycling, not illegal waste disposal, under Code Section 80.14(f), as long as the pile doesn't turn into a nuisance. If a compost pile creates odor, pests, or other nuisance conditions, it loses that protection and becomes a prohibited accumulation of solid waste.

Key details: Governing section: § 80.14(f). Composting classified as: recycling, not disposal. Condition: pile must not become a nuisance. Bin design or size limit: none stated. Responsible parties: owner, occupant, tenant, agent.

A compost pile that becomes a nuisance, through odor, pests, or unsanitary accumulation, loses its Section 80.14(f) protection and is treated as an unlawful accumulation of solid waste, enforceable under the chapter's general penalty framework in Sections 80.16 and 80.17, which allows a code compliance officer to issue a solid waste citation and refer repeat violations to the Special Magistrate.

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

The Bottom Line

Port St. Lucie's landscaping rules rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Port St. Lucie is broadly strict or permissive.
