Seattle CTR Ordinance: Program Requirements

In 1991 the Washington State Legislature adopted the Commute Trip Reduction (CTR) Law, RCW 70.94.521-527, requiring certain jurisdictions and employers to adopt plans and programs that help reduce drive-alone commutes. Consistent with the state’s requirements, the City of Seattle adopted its first commute trip reduction plan as Seattle Municipal Code Chapter 25.02.

Basic Requirements for Employers: An employer with 100 or more employees who report to work at a single site between 6 and 9 a.m. is subject to the law and must:

  • Appoint and maintain an individual to act as an Employee Transportation Coordinator (ETC) to be the primary contact between the employer and the City and to administer and promote the employer’s CTR program.
  • Develop and promote a program that helps employees reduce drive-alone commute trips.
  • Submit a program report to the City for review and approval once every two years.
  • Exercise a good faith effort by collaborating with the City in its administration and implementation of the law.
  • Conduct a commuter survey once every two years to measure employees’ drive alone rates.

Program Requirements

  1. Display contact information for the ETC prominently at each worksite.
  2. Distribute CTR Program Information to employees at least twice a year and to each new employee when the new hire begins employment.
  3. Program Elements – An employer’s program must contain at least two of the following:  
    • Bicycle parking racks and/or lockers, changing areas and showers for employees who walk or bicycle to work;
    • Ride-matching services to facilitate employee carpooling and vanpooling;
    • Subsidies for public transit fares;
    • Vanpool vehicles;
    • Subsidies for carpool and vanpool participation;
    • Use of employer-owned vehicles for carpool and/or vanpool commute trips;
    • Alternative work schedules, such as a compressed workweek, that reduce the number of commute trips between 6:00 and 9:00 a.m. by enabling a full-time employee to eliminate at least one (1) workday every two (2) weeks;
    • Flexible work schedules that allow employees to adjust their arrival and departure times in order to accommodate transit, car-pool and van-pool schedules;
    • Preferential parking for high-occupancy vehicles;
    • Free or reduced parking charges for high-occupancy vehicles;
    • Custom bus service to the work site;
    • Special loading and unloading facilities for transit, carpool and/or vanpool users;
    • Rewards and incentives for employees who do not use parking facilities;
    • Institute or increase parking charges for single occupant vehicle commutes;
    • Telecommute arrangements so employees can eliminate a commute trip by working from home or at a work center closer to home;
    • A shuttle or circulator service between the worksite and nearby park-and-ride facilities or transit centers;
    • Attend at least four meetings of a local transportation management association, transportation management organization, or employer transportation network group each year;
    • Other programs or facilities that have demonstrated effectiveness at reducing vehicle miles traveled or drive-alone commutes.
