About
The Westside Transportation Alliance works with its partners and Washington County employers to reduce single-occupant-vehicle trips, reduce green house gas emissions, foster economic vitality, improve health, and enhance the efficiency of our regional transportation network.
As the sole Transportation Management Association in Washington County the WTA has offered workplace services and programs that help employees commute to work by transit, carpool, vanpool, walking and biking since 1997.
Staff
Heather joined the WTA after three years at the Lloyd Transportation Management Association in Portland, Oregon, where she managed their bike and employee outreach programs. She received her Masters in City and Regional Planning from the Georgia Institute of Technology after teaching outdoor education for several years at schools in both Atlanta and Portland, Maine.
During her tenure at the Lloyd TMA, Heather worked with member businesses to create bike parking plans and install over 180 bike parking stalls, developed an on-line incentive program for employees taking alternative transportation, and managed an individualized marketing program designed to encourage employees to commute by bike, transit, carpooling, or walking.
