Tree Risk Assessment in Columbus, OH

Columbus requires a Forestry permit for any project that removes, prunes, grinds the stump of, or works within the critical root zone of a public tree. Street trees always need a permit, regardless of condition. The tree company's ISA Certified Arborist submits the application. There's no application fee, but replanting or a mitigation fee may be required.

Silver and Norway maple: large older yard trees; storm breakage and surface roots Ash: dead or declining unless treated Callery pear: invasive in Ohio; frequent removal

Removal, pruning, stump grinding, or any work in the critical root zone of a public tree needs a Forestry permit, with no fee to apply, though replanting or a mitigation fee may be required.

The 2012 derecho is the benchmark; strong summer storms regularly topple trees in central Ohio.

Emerald ash borer moved through Franklin County years ago; backyard ash left untreated are now brittle.

Older central neighborhoods have small lots, alleys and overhead service drops, so removals are often rigged in sections. Suburban lots in the outer ring have more room for a lift but frequent fences, pools and play sets under the canopy.
