Atlanta proposes tree-preservation targets for single-family lots of 5,000 square feet or more

An ordinance listed for second reading on the Community Development/Human Services Committee’s Sept. 29 draft agenda proposes new tree-preservation standards for single-family development in Atlanta. The proposal, 26-O-1533, is not an enacted rule; its text says the amendments would take effect upon approval.

For individual lots of at least 5,000 square feet, one proposed route would preserve at least 50% of total tree diameter and either 60% or 75% of priority-tree diameter, depending on lot size. Lots under 5,000 square feet would generally be exempt from this section’s preservation requirements, except where the city arborist determines a tree need not be removed for construction.

Instead of meeting the diameter targets, a project could preserve as many trees as feasible outside a development footprint whose size varies by lot. For subdivisions, the proposal also addresses meeting preservation requirements lot by lot or through tree-save areas established across the parcel before subdivision. Its definition of a tree-save area bars construction activity there, including access and material storage.
