Mayor Vincent Gray, the DC Housing Authority (DCHA) and Zipcar today announced that Zipcar, the world’s leading car sharing network, is expanding car sharing availability to DCHA public housing sites across the District to provide alternative transportation options for local residents. As part of the new program, Zipcar will place nine new car-sharing vehicles at DCHA locations for use by local residents. DCHA is one of the first housing authorities in the nation to partner with Zipcars in bringing affordable car sharing to public housing residents. An alternative to car ownership, Zipcars can be reserved for as short as an hour or for several days. National studies have shown that, depending on total distance driven, a car-sharing program can save members up to 70 percent of their total transportation costs.
