Prosper Portland (formerly Portland Development Commission) is a semi-public agency that plays a major role in downtown development; city voters created it in 1958 to serve as the city's urban renewal agency. It provides housing and economic development programs within the city, and works behind the scenes with major local developers to create large projects. In the early 1960s, the Portland Development Commission led the razing of a large Italian-Jewish neighborhood downtown, bounded roughly by I-405, the Willamette River, 4th Avenue and Market street. Mayor Neil Goldschmidt took office in 1972 as a proponent of bringing housing and the associated vitality back to the downtown area, which was seen as emptying out after 5 pm. The effort has had dramatic effects in the 30 years since, with many thousands of new housing units clustered in three areas: north of Portland State University (between I-405, SW Broadway, and SW Taylor St.); the RiverPlace development along the waterfront under the Marquam (I-5) bridge; and most notably in the Pearl District (between I-405, Burnside St., NW Northrup St., and NW 9th Ave.).
