Commute Trip Reduction

What is CTR?

If your worksite has 100 or more employees arriving between 6–9 AM, your company may be subject to Washington State’s Commute Trip Reduction (CTR) law. Some employers are also affected as a condition of a City permit. Employee Transportation Coordinators (ETCs) and large employers play a critical role in reducing drive-alone trips and promoting transit, biking, walking, teleworking, and alternative work schedules.

Basic requirements for employers

• Appoint an Employee Transportation Coordinator (ETC) as the primary contact with the City.
• Develop and promote a CTR program that helps employees reduce drive-alone commute trips.
• Conduct an employee survey every two years to measure progress toward goals.
• Complete an annual program report each year.
• Exercise good faith effort by collaborating with the City on administration and implementation.

What transportation benefits do locals value?

We asked people who live, work, or spend time in Tukwila which programs and amenities they would like to see in their community, school, or workplace. The survey results reflect the top programs employers and facilities can provide to support healthier, happier commutes.
