A Message From Steve Bellone, County Executive


Welcome to the Suffolk County Industrial Development Agency website. We understand that for a region to thrive, it must have a vibrant and growing business sector.

In Suffolk County, we have made a commitment to an innovation economy by supporting cutting-edge technologies, industry sectors such as life sciences, and the revival of manufacturing across the region.

A major initiative we have put in place to support the innovation economy and long-term economic progress is our Connect Long Island Economic Development Plan. This public/private initiative targets critical regional transportation, housing and lifestyle issues that are vital for sustainable economic growth and the attraction and retention of a diversified workforce.

5 Major Components of Our Connect Long Island Plan:


  • Emphasize transit-oriented development—downtowns with diversified living options that are accessible to public transportation with amenities attractive to varied age populations.
  • Expand rail transportation of the Long Island Rail Road—Long Island’s mass transit rail system—to enhance access across Long Island as well as to New York City.
  • Develop north-south mass transit connections across Suffolk County for greater accessibility.
  • Enhance connections to the county’s research and educational institutions.
  • Create enhanced transit connections between the county’s recreational assets (award-winning beaches, parks, golf courses, etc.) and the county’s downtown hubs.
