HEMPSTEAD - Officials say there is a new proposal to turn the Nassau Coliseum site into a biotech campus. 

Developer Don Monti is behind the idea, according to a Wall Street Journal report.

Monti says the high-tech offices would be linked to a 92-acre residential, retail and commercial development by light rail or a special bus route. 

Monti says the plan would cost between $2 billion and $3 billion to build.
