The company that owns Mall of America is looking to develop a 47-acre site in Woodland Hills that once housed an Aerojet Rocketdyne engine manufacturing facility, an industry group reported Tuesday.

CoStar, a real estate information and marketing firm, said Triple Five Group Ltd. is negotiating to buy the property at 6633 Canoga Ave. in the Warner Center business development from Rocketdyne’s former parent company, United Technologies Corp.

James Abbott, executive director of Realty Advisory Group Inc. who holds the sale listing for United, said he could not comment on the status of the buyer or the property — one of the largest redevelopment sites in Los Angeles — because of a nondisclosure agreement.

CoStar said Triple Five has contacted several governmental agencies about the site including the office of Los Angeles City Councilman Bob Blumenfield, whose district includes the Rocketdyne site.

Jake Flynn, a spokesman for the councilman, acknowledged Tuesday that Triple Five met with Blumenfield’s office a year ago and more recently a few weeks ago.

“They discussed the types of things they’ve done with Mall of America and other projects they have,” Flynn said. “It’s not uncommon for folks to come back after a year to check back in. They came back to discuss their pitch.”

Triple Five didn’t present a formal proposal for the site, Flynn said, noting that others have also inquired about developing the land.

“Our staff has met with several people over the years regarding that property,” he said. “One potential buyer even wanted to build a circus there. We also proposed that property in a bid for Amazon’s second headquarters.

“When something is formally submitted to us, that’s when our laser focus comes in. But many of these sorts of things fizzle out … so we stay away from it until something formal is presented.”

CoStar said the property is expected to sell for roughly $150 million, according to a source who was previously involved in a portion of the deal.

The site is being marketed as an urban neighborhood, CoStar said, with up to 6 million square feet of development including 3,950 residential units, 1.1 million square feet of office space, 200,000 square feet of shops and restaurants and a 210-room hotel.

Plans for the proposed project also include assisted living, and cultural and education space.
