Vallejo's Invasive Plant Rules: The Rules That Matter

Every city handles invasive plant rules a little differently. In Vallejo, California, there are 2 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.

Prohibited Species

Vallejo's water-efficient landscape ordinance flatly bars invasive plant species, specifically those on the California Invasive Plant Council's list, from any landscape design plan. The prohibition applies to new construction of 500 square feet or more and rehabilitated landscapes of 2,500 square feet or more requiring a permit or design review. Section 16.504.09.G.3.g controls.

Key details: Governing section: 16.504.09.G.3.g. New landscape trigger: 500 sq ft or more. Rehabilitated landscape trigger: 2,500 sq ft or more. Invasive-species list used: California Invasive Plant Council. Review body: Planning division plan check.

Because the invasive-species clause is enforced at the plan-check stage under Section 16.504.09.E, a design listing a Cal-IPC species is simply denied and must be resubmitted before city approval. Installing invasive species without an approved plan, or diverging from the approved design after installation, falls under the city's general penalty, Section 1.12.010: an infraction with a $100-$500 fine or a misdemeanor with a $500-$1,000 fine and up to six months in jail.

Tree-of-Heaven Removal

Vallejo's tree protection code names Tree of Heaven (Ailanthus altissima) as one of six fire-prone species the planning director can approve for removal near buildings, skipping the citywide 3-to-1 replacement mandate. Removal still needs a qualified arborist's report confirming the tree stands within 100 feet of a structure. Municipal Code Section 16.504.07 governs the process.

Key details: Governing section: 16.504.07.B.5. Listed fire-prone species: Six, including Tree of Heaven. Distance trigger: Within 100 feet of a structure. Standard replacement ratio: 3 new trees per tree removed. Fire-prone species: Exempt from 3:1 replacement rule.

Vallejo enforces Chapter 16.504 through its general penalty chapter, Section 1.12.010: unauthorized tree removal is cited as an infraction ($100 to $500 fine) or a misdemeanor ($500 to $1,000 fine, up to six months in county jail, or both), at the code enforcement officer's or city attorney's discretion, with each day the violation continues counted as a separate offense.

The Bottom Line

Vallejo's invasive plant 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 Vallejo is broadly strict or permissive.
