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.
PARK BROCHURE
ABOUT COSTA MESA
Costa Mesa is nestled in a sweet spot of Orange County. Irvine and John Wayne Airport border the city to the east, and Newport Beach runs along the southwest. Arterial freeways pass through Costa Mesa and provide easy access to the area from across the metro. The employer base is diversified, and a world-famous mall, South Coast Plaza, is a cornerstone of the city and helps feed demand for all property types.
The office node north of the I-405, a freeway that is undergoing an improvement project that will add one regular and one express lane in each direction up to the L.A. County line, and within a stone’s throw of South Coast Plaza is home to some of the most prominent office towers in the area. Notable tenants include IBM, Experian, Comerica Bank, and Latham & Watkins, among others.
Vacancies tend to be at the higher end for Orange County. Tenants have access to prominent office towers, an adjacent airport, and world-class shopping, which elevates rent levels toward the top of the county. However, Costa Mesa still offers a more affordable option to tenants who might be priced out of the more expensive areas such as Irvine and Newport Beach but wish to have many of the same area amenities.
