PARK OVERVIEW

Harbor Gateway Business Center is a 75-acre master-planned business park that combines building types totaling approximately 843,000 square feet. Flexibility, expandability, efficiency and architectural excellence are the keys to Harbor Gateway’s ability to attract multi-use space requirements ranging from multi-tenant to corporate headquarters. For expansion-minded companies, Harbor Gateway offers an existing network of underground conduits, which provides secure telecommunications and data networking connections easily and seamlessly. Extensive use of landscaped areas, including benches, pedestrian pathways, green belts, and rose gardens, complement the innovative architectural theme of the park and create a pleasant working environment. Harbor Gateway Business Center offers a prestigious business setting with an on-site café and tenant catering services. A special events center is conveniently located on the grounds to accommodate company events of any size. The site is situated less than five miles from John Wayne Airport and offers immediate access to the 405, 55, and 73 freeways and the San Joaquin Hills Transportation Corridor. The site is minutes from the Orange Country Theater District, overflowing with art galleries, museums, and performing arts theaters. The area is home to the Segerstrom Center for the Arts, Orange County Museum of Art, and public art is peppered across the urban-suburban landscape. Along with a thriving arts community, tenants enjoy abundant dining and shopping options. The neighborhood has everything from authentic taquerias to classic SoCal fast food joints. South Coast Plaza is two miles from the business center and offers big-box department stores, chic boutiques, and designer shops.

The Certificate of Partnership for C.J. Segerstrom and Sons was formally executed on the 15th of November 1937, in Santa Ana, California. The partnership included William O. Segerstrom, Fred A. Segerstrom, B.C. Segerstrom, Harold T. Segerstrom, Veronica P. Segerstrom, Anton H. Segerstrom, and Nellie Ruth Segerstrom. There was a short time when the business was referred to as Segerstrom Brothers but returned to C.J. Segerstrom & Sons when Henry T. Segerstrom joined the family business in 1948. Ownership of the business was held in undivided interests until the mid-1950s, when two of Henry T. Segerstrom’s uncles pass away. Both men were bachelors with no community property protection. Outlined in William and Fred’s will, Anton and Harold Sr. would inherit, as individuals, the total interests of their two deceased brothers’ shares in the family business. To settle their estates, the firm would need to sell nearly 700 acres of farmland in order to raise the funds to pay the inheritance.
