Lake Union the picture is similar. Quite a few older buildings survive, but few retain their historic uses. In April 2008, the new Lake Union Park opened to the public with a pedestrian bridge across the western waterway, a walkway along the waterfront, of green space, landscaping and much more. The park was completed in 2010. The historic ships wharf provides long-term moorage for historic vessels; and the Maritime Heritage Center will provide an array of cultural, educational, and recreational activities. Vessels currently moored at the wharf include the steamer Virginia V, the lightship Swiftsure, the tug Arthur Foss, the fireboat Duwamish, and the salmon troller Twilight. The schooner Wawona was also moored nearby at Northwest Seaport until it was dismantled in 2009. Several smaller historic boats are just to the east at the Center for Wooden Boats. In December 2007, Amazon announced it would be consolidating its Seattle offices in South Lake Union; occupancy began in 2010.

South Lake Union is also home to Denny Park, the oldest park in the city. Future as a hub for life sciences Due to recent development plans by Paul Allen's Vulcan Inc., as well as other prominent developers, South Lake Union is becoming a hub for life science organizations. Some in the area include: Fred Hutchinson Cancer Research Center, the Allen Institute for Brain Science, the Allen Institute for Cell Science, Zymogenetics, Battelle, Seattle Biomedical Research Institute, Seattle Children's Hospital, PATH, Rosetta (now part of Merck & Co.), Bio-Rad, and University of Washington Medicine. The South Lake Union Campus of the University of Washington School of Medicine now includes 1250 people (researchers and staff) in four buildings. The oldest is the Brotman Building (the former home of Washington Natural Gas, when it was known as the "Blue Flame building") at 815 Mercer St, which houses 4 floors of biotechnology and medical research laboratories. Among the varied research areas are four Centers, focused on Allergy & Inflammation, Cardiovascular Biology & Regenerative Medicine, Lung Biology and Translational Medicine in Women's Health. The plan for development of a biotechnology hub in South Lake Union has been somewhat controversial, as it is seen by some as an example of influential private companies receiving benefits from the city. There were early worries that
