No Portland buildings are among the tallest in the United States, but the city is home to four buildings over 500 feet (152 m). Overall, Portland's skyline is ranked (based on existing and under construction buildings over 500 feet (152 m) tall) second in the Northwest (after Seattle), fifth in the Pacific Coast region (after Los Angeles, San Francisco, Seattle and Las Vegas), and 25th in the United States.
The city is undergoing an era of high-rise construction, especially in the South Waterfront area, where several residential towers and an office building have been built over the past few years, including the John Ross Tower. More residential buildings will be built close to the Willamette River as development of the South Waterfront progresses. Meanwhile, in Downtown Portland, Park Avenue West Tower, a 30-story skyscraper, resumed construction in 2013 after a four-year suspension due to the 2008 Financial Crisis and is now completed. At 502 feet (153 m), Park Avenue West is the fourth-tallest building in the city.
