Tree Boxes and Street Trees Belong to the DC Government Which Regulates Them

Street trees and tree boxes belong to the DC government. Typically, private property in Georgetown starts ten feet in from the street curb (“your” sidewalk belongs to the DC government). The DC government has a series of regulations about tree boxes, street trees, and “special trees” on private property.

DC Law Requires a Permit to Remove a “Special Tree” That Is On Your Own Property
Private property trees of 55 inches or more in circumference, which is equivalent to 17.5 inches or more in diameter, could require a Special Tree Permit. Read about Special Tree removal here >

Tree Box Regulations
DC government regulations govern what can be done in tree boxes. Some highlights:
Borders: No border, such as a fence or railroad tie, is permitted on the side facing the curb.
Planting: Plants, such as flowers, must “have a shallow root system” and be less than 18 inches high. 
Removal: “A tree space beautification effort that is not in compliance with this section...may be removed with sufficient notice by the Department of Public Works.”

However, be warned the part of these regulations about the borders and fencing appear to have been superceded by the UFA’s later “ornamental street fence specification,” which provide very detailed standards for such fences. Read more here >
