West Windsor Developing New Ordinance to Address Bamboo

West Windsor Township is moving toward introducing an ordinance to regulate bamboo and address the problems that can occur when it spreads beyond the property where it was planted.

The purpose of the ordinance is straightforward: prevent new bamboo problems, protect neighboring properties and public infrastructure, and create a clear process for addressing existing bamboo that spreads or is located too close to property lines, rights-of-way, easements, drainage facilities, and other protected areas.

The need for clearer local regulation has become more significant as New Jersey has formally classified running bamboo, from the genus Phyllostachys, as a prohibited invasive species under the state’s Invasive Species Management Act. The law recognizes that invasive species can threaten native species, natural resources, ecosystem function, human health, and economic vitality, and establishes phased restrictions on the propagation, importation, sale, and distribution of listed species. The measure was enacted as P.L. 2025, c. 290, following passage of Senate Bill S1029 and its Assembly counterpart, A4137.

Bamboo can spread aggressively through underground rhizomes, making it difficult to contain once established. It can cross property lines, damage landscaping and hard surfaces, interfere with drainage systems and utilities, and create costly and prolonged disputes between neighboring property owners.

Although West Windsor would not be the first municipality in New Jersey to adopt a bamboo ordinance, it would be among a relatively small number of communities that have established specific local rules governing bamboo planting, containment, removal, and enforcement.

Developing the ordinance, however, has been more complicated than simply prohibiting a plant.

A Collaborative Drafting and Review Process

The initial draft was developed through the work of the West Windsor Shade Tree Commission, which identified the need for a local ordinance and researched approaches used by other municipalities.

The Township administration then reviewed the proposal and prepared revisions intended to make the ordinance more practical to administer and enforce. Mayor Hemant Marathe has supported moving the proposal forward while its provisions continue to be refined with Township staff and legal counsel.

The Township Council recently held an initial public discussion of the ordinance. Council members raised questions about enforcement, property-owner responsibilities, containment requirements, deadlines, penalties, the impact on neighboring properties, and how the Township should address bamboo that spreads beyond the property where it originated.

Residents also participated in the discussion and provided important perspectives based on their experiences with bamboo and its effects on their properties.

Based on feedback from the Shade Tree Commission, Township administration, Mayor, Council, professional staff, legal counsel, and residents, a final draft is now being prepared and is expected to be introduced at the August 3 Council business meeting.

What the Ordinance Is Intended to Do

The current direction is to regulate all bamboo species rather than require residents and Township staff to distinguish among running, clumping, invasive, and noninvasive varieties.

The final ordinance is expected to:

• Prohibit the planting of new bamboo anywhere in the Township.

• Establish a 15-foot buffer between existing bamboo and property lines, rights-of-way, easements, and other protected areas.

• Require owners to contain or remove bamboo that violates the ordinance.

• Establish standards for underground containment barriers.

• Require Township review of containment and remediation plans.

• Require plans to explain how removed bamboo will be transported and disposed of.

• Establish penalties while providing a notice and remediation period before those penalties begin.

• Allow the Township to address bamboo that threatens public property, infrastructure, drainage facilities, utilities, or public safety.

• Preserve the ability of affected property owners to pursue private legal remedies when bamboo spreads between neighboring properties.

Enforcement is expected to rely on resident complaints, Township inspections, notices of violation, approved remediation plans, required containment or removal, and penalties when a property owner fails to correct a violation within the established time frame.

The ordinance is also expected to provide for inspections of containment systems to confirm that corrective work complies with the approved plan and technical standards.

Balancing Enforceability and Practicality

One of the central challenges is ensuring that the ordinance is strong enough to solve real problems while remaining fair and workable.

Bamboo can spread through underground rhizomes and may continue growing beyond the area where the visible plants are located. Effective remediation can require excavation, removal of roots, installation of containment barriers, disposal of plant material, and ongoing monitoring.

The ordinance therefore must clearly explain:

• What constitutes a violation.

• Which property owner is responsible.

• What work must be completed.

• How much time an owner has to comply.

• Who reviews and approves a remediation plan.

• How containment systems will be inspected.

• When penalties may begin.

• How unusual circumstances, extensions, and appeals will be handled.

The initial legal review found that much of the proposed framework was sound but recommended several corrections and refinements to improve clarity, enforceability, fairness, and due process. These recommendations are being considered as the final language is prepared.

Questions involving bamboo spreading from one private property to another are especially complicated. The ordinance can require the responsible owner to stop the spread and complete remediation, but the Township must also respect property rights and avoid becoming the decision-maker in every private dispute between neighbors.

The Township Attorney is reviewing these issues as the final language is prepared.

Anticipated Timeline

The ordinance is expected to be introduced at an August Council business meeting. Following introduction, it will be published and scheduled for a public hearing at a subsequent Council meeting. Residents will then have another opportunity to comment before Council considers final adoption.

Once adopted and signed into law, the ordinance would take effect 20 days later, giving the Township time to publish the new requirements and prepare for implementation.

After the ordinance takes effect, enforcement is expected to begin with a complaint, Township inspection, and notice to the affected property owner. The owner would then have an established period to submit a remediation plan and complete the required work before penalties are imposed.

The Intended Outcome

The goal is not simply to adopt another regulation. It is to establish a clear, legally enforceable, and practical process that:

• Prevents new bamboo infestations.

• Stops existing bamboo from spreading.

• Protects neighboring homeowners.

• Protects roads, drainage systems, utilities, easements, and public property.

• Gives residents clear notice of their responsibilities.

• Provides a reasonable opportunity to correct a violation.

• Allows the Township to respond consistently when problems occur.

Thank you to the members of the Shade Tree Commission, the Mayor and Township administration, Council, professional staff, legal counsel, and the residents who shared their experiences and perspectives throughout this process. Developing an effective ordinance is necessarily iterative, and the work will not end with adoption. Once implemented, the ordinance can be reviewed and modified if experience shows that changes are needed. This collaborative effort is intended to produce a fair, practical, and enforceable approach that protects residents, neighboring properties, and public infrastructure, while helping West Windsor remain one of the most desirable communities in New Jersey in which to live.
