The Pearl District is a former warehouse and light industrial area just north of downtown Portland, Oregon now noted for its art galleries and upscale businesses and residences. Its boundaries are West Burnside Street on the south, NW Broadway on the east, the Burlington Northern Railroad tracks to the north, and the Interstate 405 Freeway on the west. The area has undergone significant development since the late 1990s and is now full of high-rise condominiums and warehouse-to-loft conversions.
