Less than 10 miles north of the Cornfield, Walt Disney Co. has proposed a large "creative campus" on the grounds of the former Grand Central Air Terminal, a Glendale airport that closed in 1959. Disney's plans are sketchy, but the entertainment giant has revealed plans for four district projects on the site: a 52-acre campus to house the theme park research and development operations; a 24-acre soundstage and production facility; a 27-acre media and technology campus that would have space available for lease; and another 18 acres of development to meet company or market needs. Disney was one of the earliest tenants of the Grand Central Industrial Park, which replaced the airport shortly after it closed. About 3,000 Disney research and development employees work on the site. Disney purchased the property in 1997. The site is within Glendale's 750-acre San Fernando Corridor Redevelopment Project Area, which has not seen a great deal of activity since the city created it in 1992, said Philip Lanzafame, assistant director of development services. The project is in the environmental review process, and documents are scheduled to be released this spring. City officials also are negotiating financing packages with Disney, although Lanzafame said he could not disclose the details of those talks. Contacts: John Hunter, Majestic Realty, (562) 692-9581.
