Porter County, IN Tree Protection: Parkway Planting (2026)

06(G) sets the actual planting counts rather than leaving the choice to the applicant. The greenbelt itself must run the entire length of the site's frontage, with a minimum depth of 100 feet along a Primary Arterial and 50 feet along a Secondary Arterial. 06(G)(1)(a)(vi) fixes the base planting unit for every 100 linear feet: a Primary Arterial frontage needs ten shade trees, six ornamental trees, and either thirty shrubs or six evergreen trees (evergreens may substitute for shrubs at a one-for-five ratio), while a Secondary Arterial frontage needs six shade or evergreen trees plus either six ornamental trees or twenty shrubs.

Frontage beyond the first 100 feet is prorated and rounded up to the next whole tree or shrub, so a partial increment still triggers additional planting. The greenbelt may also incorporate steps, walks, terraces, bike paths, lighting standards, signs, and mounding, but it must otherwise stay unoccupied by structures; a perimeter fence, if used, must be masonry, stone, wood or metal (or a synthetic material simulating those), between 36 and 72 inches tall, and is subject to Plan Commission approval, while a mound may not exceed 6 feet in height with side slopes no steeper than 3:1, and continuous levee-like mounds are banned outright.

A separate, less intensive planting schedule applies to some ARO parcels: under item 2 of the same landscaping section, a Primary Arterial frontage instead requires five shade trees, three ornamental trees, and either fifteen shrubs or three evergreen trees per 100 feet, showing the standard varies by which ARO applicability track a parcel falls under. 08(C) and Chapter 07's Perimeter Landscaping standard, so a developer does not have to satisfy both sets of tree requirements at once.
