Although not an officially recognized neighborhood, its borders can be considered to be Naito Parkway to the west, the Willamette River to the east, and the Marquam Bridge (which carries I-5) to the south.
[1] The land which RiverPlace occupies was formerly part of Harbor Drive, an expressway running along the west bank of the Willamette River.
In 1976, Harbor Drive was demolished and replaced by Waterfront Park for much of its distance, except for the 73-acre (30 ha) area where RiverPlace would be developed.
The Portland Development Commission invested $6 million in improving the infrastructure and livability of the area throughout the early 1980s, including a marina by 1985.
1985 also marked the opening of the RiverPlace hotel, a small condominium complex with amenities, a floating restaurant on the river, a marina, and boutique shops.
