Full Breakdown
Gwinnett County's UDO requires street trees for non-residential projects in Overlay Districts, the MU-N, MU-C, and MU-R zoning districts, or when imposed as a zoning condition. Trees must sit no closer than 11 feet to the edge of pavement or curb, at a rate of one tree per 50 linear feet of frontage on both sides of the street, with Overlay District trees at least 3-inch caliper. A street tree plan needs GCDOT or GDOT approval before a development permit issues, and the property owner is responsible for ongoing maintenance.
Violations & Fines
Failing to submit an approved street tree plan blocks issuance of the development permit; unmaintained or removed street trees violate the owner's maintenance duty under UDO § 620-40.E, enforced through Chapter 120.
