Tree Trimming in River Vale NJ: Right of Way Limbs, Topping Rules, and Timing

Table of Contents

River Vale now holds owners responsible for street trees next to their property, and a permit covers any limb six inches or more across. This guide covers tree trimming in River Vale, from the ordinance to the topping rule and timing.

Tree Care in River Vale, NJ

River Vale is a township in Bergen County. According to Wikipedia, it was incorporated on April 30, 1906, from parts of Hillsdale Township and Washington Township, covers 4.31 square miles and counted 9,909 residents in the 2020 census. The Hackensack River runs along its eastern border, where it is dammed to form Lake Tappan, and Pascack Brook marks the southern edge. Trees and water shape the land here, and tree trimming in River Vale is a regular job for homeowners with a maple over the driveway or an oak over the roof.

The township changed its tree rules this year. The township Tree Removal page tells residents with trees within 10 feet of the curb to review Ordinance 480 of 2026, which it calls recently passed. The ordinance text lists a first reading on July 13, 2026 and a public hearing on August 10, 2026, and it amends Chapter 225 of the township code, now titled Tree Removal and Maintenance. Most of the new language answers one question: who looks after the trees between the curb and the property line.

This guide covers what the ordinance says about trimming, why topping is the cut to avoid, and when the work is best done. We read the township page and the ordinance on November 3, 2026. Rules change, so confirm the current requirement with the township before any work starts. Reliable Tree Service has been family owned since 1960 and works across Hudson and Bergen counties from Cliffside Park.

Our approach to trimming starts on the ground. We walk around the tree, look at the shape of the crown, check where the limbs reach over the house, the wires and the street, and find out whether the tree stands on the homeowner’s lot or in the right of way. Those answers decide how much comes out and whether the township needs to be asked first.

The work itself is described on our tree trimming and pruning page, and routine yearly care is covered by our tree maintenance service. Nearby towns have rules of their own, as our guides to trimming in Waldwick and pruning in South Hackensack show.

Street Trees, Right of Way Limbs and Township Permits

The ordinance defines a street tree as a tree growing within the public right of way in the township. It then puts the burden on the owner next door: property owners are responsible for the maintenance, including removal, of all trees within the public right of way adjacent to their property. In plain terms, the strip of grass between the sidewalk and the street may be township land, but the trimming is the homeowner’s job. A tree there is not someone else’s problem.

That responsibility comes with a permit. Section 225-12 of the ordinance says that nobody except township employees acting under the Enforcement Officer may do certain acts in the street right of way or an easement without a written permit from the Enforcement Officer. The first item on the list is to cut or trim any limb six inches or more in diameter. It also covers breaking limbs, climbing with spikes, disturbing the roots, injuring the tree, spraying it with a chemical and removing a living tree.

The list goes further than most homeowners expect. A permit is also required to plant any tree or shrub, to fasten a rope, wire, sign or other device to a tree except support ropes or wire, and to close the open space at the base of a tree so that air, water or fertilizer cannot reach the roots. It forbids piling building material, or dumping mortar or cement, within six feet of a tree or its canopy.

Trees on private land follow a different path. The township page says that for the removal of trees on your property you submit a Tree Removal Application to the Zoning Department. The ordinance adds that a permit is required before removing more than one tree on a tax lot within any twenty four month period, and that any removal requires the replacement of two trees for every tree removed, with donations to the Shade Tree Fund approved when replacement is not feasible. Trimming is not removal, but a trim that goes too far can kill a tree and turn one job into the other.

Tree trimming in River Vale: questions to settle before the first cut

  • Whether the tree stands in the right of way
  • Whether any limb is six inches or more across
  • Whether roots or soil near the trunk will be disturbed
  • Who will request the written permit and keep a copy

Edward Hufnagel, who owns Reliable Tree Service, puts it this way: “Trimming a tree is a series of small decisions. You take what is dead, crossing or hanging, and you leave the structure the tree built over many seasons. The cut you skip matters as much as the one you make.”

Why Topping Is the Cut to Avoid

The last item in Section 225-12 is the one with the most weight behind it. The ordinance forbids topping any tree in the right of way without a permit, and it defines topping as the severe cutting back of limbs to stubs larger than three inches in diameter within the crown, to such a degree that the canopy is removed or the tree is disfigured. It adds that trees severely damaged by storms, or certain trees under utility wires where normal pruning is impractical, may be exempted at the discretion of the Enforcement Officer.

The township did not invent that concern. A February 2026 post from University of Illinois Extension says topping creates a more hazardous tree and does not lower its height over time. Removing most of the leaf buds takes away the tree’s ability to make food, so it spends stored energy on dense, fast growing shoots that are weakly attached and prone to breaking. The same page says the tree can regain its original height within a few years.

Stubs are the other problem. The Illinois post notes that stubs seal slowly or not at all, especially those over two inches across, and that they leave openings for insects and decay. A topped tree may look smaller for a season, but it carries a crown of weak new growth over the same house and the same driveway. Topping may cost less than removal on the day, yet topped trees need continuing work and often end up coming down anyway.

For a tree that is too large for its spot, the page recommends crown reduction instead. That means cutting a branch back to a side branch at least one third the diameter of the piece removed, which leaves no stub and keeps the natural form of the tree. It also says to choose someone knowledgeable, such as a certified arborist, and to avoid anyone who offers topping as a service. We follow the same rule on every job, and a tree under wires is where it matters most.

Cuts that keep a tree healthy

  • Cut back to a side branch, not to a stub
  • Remove dead, crossing and hanging limbs first
  • Reduce a crown by small amounts over several visits
  • Leave the branch collar at the trunk intact

A good trim is hard to notice afterward. The tree looks like itself, only with more light under it and less weight over the roof.

Timing Tree Trimming From Fall Cleanup to Winter Pruning

The calendar matters as much as the cut. A winter pruning handout from the Hunterdon County Rutgers Master Gardeners says late February to early March is the best time for pruning many landscape trees. Without leaves it is easier to see the shape of the tree and anything out of proportion or structurally unsound. Cuts on dormant trees do not stimulate new growth, which produces less overall stress, and many disease organisms and pests are dormant too.

The handout lists exceptions. Oaks and elms should only be pruned in winter to avoid oak wilt and Dutch elm disease, while spring flowering trees are usually pruned right after bloom. Maples, birch and beech may bleed sap from wounds if pruned in winter, but the handout says the sap loss does not hurt the tree and that those trees can be pruned in late spring once the sap stops running. Dead branches can be removed at any time, which is why a November walk around the yard is still worth doing.

Look for structural problems first. The handout names crossed branches that rub and damage each other’s bark, tight V crotches under 45 degrees, and codominant leaders, where two stems compete and one is likely to break as both grow. It advises keeping the strongest branch and cutting the other out, and making each cut just above the branch collar, where the branch thickens to meet the trunk, because the collar heals the scar quickly. It also says that cutting branches while a tree is young stresses it less than sawing off big limbs later.

Hand tools handle the small work, but the handout is plain that overhead branches and questions about specific trees are a reason to call a professional. Any limb that reaches the wires belongs to a professional, and so does any limb six inches or more across in the right of way, because the township expects a permit for it. Our storm proofing and repair service handles trees that were already weakened before the weather arrived.

A November walk around the yard

  • Note dead limbs and hanging branches overhead
  • Look for crossed branches that rub together
  • Check unions where two stems meet in a tight V
  • Photograph anything you plan to ask the township about

Notes and photographs from this walk make a late winter visit faster, and they give the township a clear record if a permit is needed.

Protecting River Vale Trees Through the Winter

River Vale has put its expectations in writing. Street trees are the owner’s to maintain, limbs six inches or more across need a permit, and topping is on the list of acts that require one. Use that framework. Decide who owns the tree, look at the size of the limbs, plan cuts back to side branches and save structural pruning for late winter where the species allows. Our other local guides are in the River Vale tree care articles section.

When you hire help, the New Jersey Board of Tree Experts says it is mandatory to hire a tree care business registered with the state that employs a Licensed Tree Expert or Licensed Tree Care Operator. It advises asking to see the business registration, the proof of insurance and the name and license number of the licensed person. We are family owned since 1960, and we will tell you plainly what a tree needs and what the township asks.

Our crews are ISA Certified Arborists and New Jersey Certified Tree Experts. Call Reliable Tree Service at (201) 943-4141 to schedule tree trimming in River Vale, or have us look at a tree that may need to come down through our tree removal services.
