Irvine Spectrum Claims Large Share of R&D; Leases

Of the 2.19 million square feet of research and development space leased in Southern Orange County, 53%, or 1.2 million square feet, has been leased in the massive Irvine Spectrum, according to John O’Donnell of O’Donnell, Armstrong, Brigham & Partners.

The Irvine-based firm has developed 1,661,389 square feet in the Spectrum--of which 1,142,810 is leased, according to the company’s John Vogt.

In addition to the O’Donnell firm, major joint-venture developers with the Irvine Co. in the 2,600-acre project include the Koll Co., Sammis Co., Birtcher and Legacy.

“The Spectrum is considered by many to be the most successful commercial/industrial master-planned development in the United States,” Vogt said. “Most of the 10 million square feet of space was leased before completion and the development has 15,000 employees working for 500 companies.”
