Harrisburg, PA Tree Protection: Parkway Planting (2026)

Chapter 10-101 of the Harrisburg Codified Ordinances makes the Department of Parks, Recreation and Enrichment the sole authority over trees on and along the streets and highways in the City. Under § 10-101.1 the Department determines the kind of tree and the alignment and location of trees, but the choice cannot prevent necessary and reasonable use of the streets, sidewalks or abutting property or the conduct of business.

Section 10-101.13 sets the stock. The Department plants, or permits to be planted, shade trees of not less than 1 1/2 to two inches in caliper, measured 18 inches above the ground, symmetrical in shape, with a trunk clean and straight without branches for a distance of four feet from the ground. Planting any species other than those on the approved list on file in the Department office is prohibited unless the Department Director approves it in writing.

Section 10-101.14 sets the layout. Newly planted shade trees go not less than 40 feet nor more than 60 feet apart, and the spacing can vary with the kind of tree. No tree is planted less than 25 feet from a curb intersection, nor less than 10 feet from a fire hydrant, sewer inlet, light standard or utility pole. No tree is planted along a street where the distance between building lines is less than 40 feet, and an open space of at least 48 inches by 48 inches must be allowed for each tree. No tree is planted on a street or highway where curbs have not been constructed.

When a tree has outgrown its 48 inch by 48 inch space, or a sidewalk was laid without allowing it, the sidewalk is repaired or relaid at the property owner's expense so that at least 12 inches is left between the base of the tree and the edge of pavement. For owner-occupied premises that duty takes effect when title is transferred and is included in the buyer's notification inspection under Chapter 8-509. Planting itself needs a Department permit under § 10-101.4, and § 10-101.18 requires seven days' written notice by regular mail to the property owner before the Department plants a street tree, unless an emergency is the reason.
