Setback Tree Plantings

What is setback planting?

Setback planting refers to the practice of planting public trees for the common good beyond the public right-of-way on private property.

What laws govern setback planting, and are setback trees “public shade trees?”

Massachusetts General Law (MGL) Chapter 87, Section 7, explicitly allows towns and cities to plant trees within 20 feet of the public right-of-way, provided written permission from the adjoining property owner is obtained first. MGL. Chapter 87, Section 1 states that trees planted under this provision are defined as “public shade trees” and thus protected by all sections of MGL Chapter 87.

Why consider setback plantings?

The public right-of-way often contains various obstructions and hazards for trees. Limited soil volume, compacted soils, overhead wires, underground utilities, sidewalks, road salt, and passing vehicles all significantly hinder a tree’s ability to thrive and survive. These conditions limit the selection of trees that can be safely and appropriately planted within these zones.

Setback plantings allow public tree managers more flexibility in working with residents to plant “the right tree in the right place.” They can provide trees with more growing space and better conditions under which to survive, and achieve their full potential.

According to the experiences of Tree Wardens around Massachusetts who have been engaging in setback plantings within their communities, setback trees tend to be healthier, more vigorous, develop better canopies and root areas, and receive better care by adjacent property owners than trees planted in similar situations within the right-of-way.
