Shoreline Community College and all its employee are subject to Washington State's Commute Trip Reduction Law (CTR). In an effort to comply with CTR, this page and its links are your campus resource for action and compliance.


From the King County website, "The law requires major employers to develop and implement an employee commute program to reduce the number and length of drive-alone commute trips made to the worksite. Local jurisdictions (cities and counties) implemented ordinances to define how the law would apply to worksites in their area. Local jurisdictions are required to provide training and technical assistance for employers."

It's Not All or Nothing

A common misconception about alternative commuting is that you have to do it 100% of the time. Not true! Sharing a ride to work one or two days a week makes a difference!

Purpose of the CTR Law

The aim of Washington’s 1991 Commute Trip Reduction Law (CTR) (RCW 70.94.521-551) is to improve our lives by reducing traffic congestion, air pollution, and fuel consumption. To achieve these goals, the state asks employers to develop CTR programs that encourage their employees to reduce their vehicle trips by using more sustainable commute options, such as buses, vanpools, carpools, biking or walking. Offering options to telework or a flexible work schedule, such as a compressed workweek, are other ways employers help reduce single-occupant vehicle trips.

Other Laws Supporting State Agency CTR Programs

RCW 43.01.220-240 provides additional support to state agency CTR programs.

RCW 43.01.230 gives agencies the authority to use public funds (including existing internal agency funds) to support their CTR programs. See Use of Public Funds Guidelines for information on how the funds may be utilized in your CTR program.

RCW 43.01.240 (1) - (3) gives agencies the authority to charge and use parking fees and directs that agencies reduce the state’s subsidization of employee parking by reducing their employee parking supply. The law also requires that where there are fewer parking spaces than employees, the spaces must be equitably distributed with no preference given to managers. If this situation exists at any of an agency’s worksites, the agency should have a parking program policy that provides equity in the way the parking is assigned.
