Permits & rules in Trenton

Trenton's Tree Removal and Replacement ordinance (City Code Chapter 287, rewritten by Ord. 24-38 on 5-9-2024 under New Jersey's stormwater rules) requires a Tree Permit from the Department of Recreation, Natural Resources and Culture before removing any street tree 2.5 in. DBH or larger or any private (non-street) tree 6 in. DBH or larger, and no tree may come down until the city reviews and approves. Application fees scale with size ($25 for 6-12.99 in. DBH, $50 for 13-22.99 in., $75 for 23-32.99 in., $100 for 33 in. and up) and removals trigger replanting of 1-4 trees of 2.5 in. caliper within 12 months or a $300-per-tree payment into the city tree fund; residents removing fewer than four category 1-3 trees per acre in a rolling five-year period are exempt from replacement, and documented hazard trees (dead, dying, structurally unsafe, with an NJ Licensed Tree Expert or arborist statement) are exempt from fee and replacement. Routine pruning is not removal, but any cutting, trimming or planting of trees on city property needs a written department permit, and under state law tree work for hire must be done by an NJ Licensed Tree Expert or Licensed Tree Care Operator.

Storm debris: Public Works runs a seasonal leaf and yard-waste program (roughly November to early January) and ward-by-ward citywide cleanups; brush must be cut to 4-ft lengths and bundled under 35 lb, with special pickups through the Street Division (609-989-3200) and no standing storm-debris program found.

Weather & timing

• Nor'easters and heavy wet snow Early- and late-season snow loads leafed-out or weak-wooded trees to failure
• Tropical storm remnants Sandy (2012) and Ida (2021) brought wind damage and Delaware River flooding
• Severe thunderstorms and derechos Summer squall lines and microbursts snap silver maples and pines
• Saturated soils Wet springs and falls loosen root plates of large oaks and maples

Best time: Late fall through winter (November-March) is best: trees are dormant, leaf-off makes structure visible, frozen ground limits lawn damage, and spotted lanternfly and other pests are inactive.

Pests & disease to watch

• Emerald ash borer Established in Mercer County since the mid-2010s; dead ash removal is a major workload
• Spotted lanternfly Mercer County was in the first New Jersey quarantine zone; swarms tree-of-heaven, maples and walnut
• Beech leaf disease Spreading across New Jersey since 2020, killing American and ornamental beech
• Bacterial leaf scorch Widespread chronic decline of pin and red oaks on New Jersey streets
• Dutch elm disease Still kills the remaining American elms in older neighborhoods
