The Pearl District is a downtown Portland, Oregon, neighborhood that served as a model for the revitalized River Market District of Little Rock, Arkansas. In the spring of 1995 thirty-eight central Arkansas business leaders and government officials traveled to Portland to study that city's regional planning activity and amenities. In particular the mixed-use condominium complexes developed by Jimmy Moses of Moses Tucker Real Estate in Little Rock are inspired in part by the Pearl District's urban waterfront community.
