McClellan Air Force Base enters a new era as McClellan Park, a thriving corporate community. This base conversion is unlike any other in the country. Working over the last 18 months, McClellan Park today opens its doors over 2.5 million square feet of space already leased to 67 tenants, creating over 5,000 new jobs. McClellan Business Park is a collaborative venture between Morgan Stanley Real Estate Funds, Industrial Realty Group, and the management team of Stanford Ranch.
