Downtown Portland lies in the Southwest section between the I-405 freeway loop and the Willamette River, centered on Pioneer Courthouse Square ("Portland's living room"). Downtown and many other parts of inner Portland have compact square blocks (200ft [60 m] on a side) and narrow streets (64ft [20 m] wide), a pedestrian-friendly combination.
Many of Portland's recreational, cultural, educational, governmental, business, and retail resources are concentrated downtown, including:
Neighborhoods like South Portland (formerly Corbett-Terwilliger-Lair Hill), South Burlingame, Hillsdale, and Multnomah, with unique residential houses and well-defined commercial and retail districts
The south Willamette riverfront along SW Macadam Ave., over 100 acres (0.4km2) of former industrial land. This area is undergoing redevelopment as a mixed-use, high-density neighborhood, with an anticipated 2,700 residential units and 5,000 high-tech jobs after build-out.
