L O C AT I O N The successful development of a cluster capitalizes on  the close physical proximity of an area’s existing resources in order to encourage collaboration and vigorous, integrated scientific activities across multiple disciplines in the life science industry: academic institu- tions, emerging and established life science companies, non-profit  institutes, related governmental entities, clinics and specialty hospitals, and venture capital. As a very significant complement to the existing Alexandria strategic operating platform in the San Francisco Bay area, during the latter part of 2004, Alexandria acquired land and related entitlements to develop approximately 1.4 million square feet of life  science and translational medicine related space at Mission Bay. These key entitled land parcels surround approximately 2.5 million square  feet of the new life science research and clinical practice campus at  the University of California, San Francisco. These entitlements provide Alexandria with a unique platform to deliver a variety of creative and innovative environments that will substantially enhance inventive and collaborative scientific thinking and processes conducted by a broad range of life science related entities. This life science cluster would be the first commercial center of its kind within the City of San Francisco.
