The University of Rhode Island this afternoon will unveil details about an ambitious proposal for a 30-acre research and technology park north of Flagg Road on the Kingston campus, a step they say is essential to expanding URI’s research power and generating revenue.

URI officials envision a mixture of faculty-led spinoff companies, satellite offices of big corporations, such as Amgen and Raytheon, and incubator space spread out over a total of six buildings. The park would sit directly across the street from the university’s developing north quadrant, which is being transformed into a life-sciences hub. The university plans to open a $60-million biotechnology center there in January 2009 and a $65-million building for the College of Pharmacy in the fall of 2010. URI also plans to build new chemistry and nursing facilities in the north campus.

University officials say it would take about 10 years to develop the parkto its full capacity, with a new building constructed every 18 months. As many as 1,000 people could one day work in the park, but URI officials say that will depend on the size and type of companies that move in.
