Zoning Code Update Packet #151

Contents of Update Packet #151 (effective 09/02/11)

This Code update is the result of the Solar and Mechanical Equipment Project and is effective September 2, 2011.

Code Update Packet: 151

Effective Date: September 2, 2011

Contact: Jessica Richman (503-823-7847)

Amends Chapters: 33.218, 33.420, 33.445


Substantive Changes:

There are two components in this project. The first relates to solar energy systems: House Bill 3516 requires that solar panels be allowed without land use review on most structures, including non-landmarks in Conservation Districts and the Design Overlay Zone. These amendments to the Zoning Code will bring the code into conformance with the legislation.

The second extends an exemption from review for rooftop mechanical equipment. The Zoning Code currently exempts rooftop mechanical equipment in design overlay zones and conservation and historic districts from review if it is on a building at least 45 feet tall and if the equipment is set back from the roof perimeter. However, for buildings that are less than 45 feet tall, the installation of mechanical equipment still triggers a design/historic review. These amendments will allow the installation of rooftop mechanical equipment on buildings less than 45 feet tall if certain standards are met.
