Overlay Zone or Plan District for Tree Permits

Information
Determine if your tree is in a specially regulated Overlay Zone or Plan District. If your property falls into one of the overlay zones or plan districts listed below, call 503-823-TREE (8733) to find out tree requirements for that area.

Overlay Zones and Plan Districts

Overlay zones consist of regulations that address specific subjects in particular areas in the City. Several overlay zones have different tree requirements than regulations of the base zones. 

Some sites within the City of Portland are located within plan districts. Some plan districts have alternative tree requirements to the base zone or overlay zone.

Why are these overlay zones and plan districts special?

Certain areas of the city have significant natural resources or environmentally or culturally sensitive features, such as floodplains, wetlands, scenic views, steep slopes, native vegetation, or historic elements. The City acknowledges these sensitive areas by restricting certain activities in order to protect resources that provide benefits to the public. These benefits include reducing stormwater runoff and erosion, enhancing water quality, retaining native vegetation, and preserving historic elements and scenic views.

In certain environmental overlay zones and plan districts, private property trees of any size may require a permit for removal. These areas include:
