Clean Air Corridor FAQs


What is the Clean Air Corridor (CAC)?

The Clean Air Corridor is a designated corridor targeted as a pollution-free zone, prohibiting smoking and the creation of air pollutants such as exhaust from idling vehicles, gas powered leaf blowers, pressure washers, and small utility vehicles.

Why was the CAC created?

The Clean Air Corridor represents a positive step forward in PSU’s ongoing efforts to provide a healthy, safe, and sustainable environment for all members of the campus community. The goal is to protect all who live, work, study or visit the campus from health concerns associated with second hand smoke and other air pollutants. Portland State is taking steps to align with other Oregon University System Universities, regional Community Colleges, and at least 10 other higher education institutions in Portland that have smoke-free campus efforts and policies.

In response to documented complaints to Multnomah County about second-hand smoke, and in an effort to provide consistency in our leadership on sustainability and our commitment to student success, a sub-group of the Executive Committee charged the Healthy Campus Initiative Team to implement the existing smoking/tobacco policy. As the heart of campus, the CAC is the most frequented area for students, faculty, staff, and guests.

Where is Clean Air Corridor be located?

The CAC is located from the north end of Lincoln Hall to the south end of Shattuck Hall. The CAC includes three of Portland State’s most used buildings: Cramer and Neuberger Halls and the Smith Memorial Student Union; and two high-profile LEED certified buildings, Lincoln and Shattuck Halls. This Corridor is viewed as the heart of campus and currently has multiple sustainability efforts underway including solar panels, hydration stations, water/energy conservation measures, emergency blue lights, recycling/composting, access to bike lanes, and proximity to the Portland Farmer’s Market, the Electric Avenue, the Eco Learning Plaza, and the planned Green Streets initiative.

When did the Clean Air Corridor go into effect?

January 1, 2013.

What does a pollution-free area include?

A pollution-free area includes no smoking, no idling vehicles, minimized use of gas-powered landscaping equipment such as mowers, small utility vehicles, and leaf blowers or electric alternatives.

How do maintenance vehicles access the park blocks and campus?

The corridor between Lincoln and Neuberger on Mill street, where the Portland Streetcar currently runs, is the designated access point.

What does the smoking policy say about smoking on Campus?

Smoking is prohibited within 25 feet from entrances and exits, air intake vents, operable windows of buildings, or where otherwise prohibited by signage. For detailed information, please see Portland State’s smoking policy.

Is smoking permitted at Trimet bus and MAX stops?

Trimet policy states that, “Smoking is prohibited on buses and trains, and where posted at bus shelters, WES/MAX stations and transit centers. If you smoke, be considerate of your fellow riders by moving away from the shelter or station. Maximum penalty: $250/exclusion.”

    Are leaf blowers really a problem?

    Sources say yes! In one hour, gas-powered leaf blowers emit as many harmful pollutants as an automobile driven over 100 miles. Learn more in this eco tip from the Center for Earth Leadership.
