What we do

The Westside Transportation Alliance works with its partners and Washington County employers to offer workplace services and programs that help employees commute to work by transit, carpool, vanpool, bicycling and walking. These services include transportation fairs, assistance with DEQ’s ECO Rule compliance, ECO surveying, events, incentive programs, and participation on local and regional planning committees.

Service Area

The WTA provides programs and services to the urbanized areas of Washington County, including the Tualatin, Tigard, Beaverton and Hillsboro areas. The cities of Beaverton, Hillsboro, and Tigard, as well as Washington County, are supporting members of the WTA.

Our History

Beaverton Transit Center

The Westside Transportation Alliance is a TMA, or transportation management association, that was formed in 1996 through collaboration with the City of Beaverton, Metro, and local area businesses. The WTA was formed in order to help companies become compliant with DEQ’s Employee Commute Options (ECO) rule. This rule requires companies that have over 100 employees to reduce the number of people driving alone to work by 10% within three years of their baseline survey. In addition to ECO Rule support, the WTA was created to decrease the number of people driving alone to work in order to decrease congestion and green house gas emissions. In addition to the WTA, there are four other TMAs in the Portland metro region including: Lloyd TMA, Swan Island TMA, South Water Front TMA, and the Gresham TMA.

The WTA is a private 501(c)(6) nonprofit. The WTA receives funding through several grant sources including federal Congestion Mitigation Air Quality funds through Metro and private foundation funds, such as the Kaiser Permanente Community Fund. In addition to grants, the WTA receives funding through membership dues as well as Washington County’s MSTIP program.
