The last piece of an initial phase of the West Oahu regional mall Ka Makana Ali‘i is scheduled to start construction later this month and will look very different than originally envisioned when done next year.

Ka Makana’s developer, Florida-based DeBartolo Development, announced its plan to finish the first half of the 1.4 million-square-foot mall Tuesday as part of a construction and ground blessing on the site in East Kapolei.

Stephanie England, the mall’s general manager, said the expansion will have a health and wellness focus with tenants including a Hawaii Pacific Health clinic, a Foodland Farms grocery, a PetSmart store, and other smaller restaurant and shop tenants.

“We’re excited to have this new growth and development as part of Ka Makana Ali‘i,” she said.

Originally, the site for what is being nicknamed “Phase 1.2” was expected to be for big-box retailers, but England said community feedback indicated that it would be better for more service-related businesses largely connected with health and wellness.

Ka Makana opened about 18 months ago with roughly 640,000 square feet of tenant space, and since then about 125 businesses have opened their doors at the mall — about half of them in 2016 and half last year. Some space is still available. Among the most recent tenants to move in were Jollibee, Koko &Palenki and Godiva around November.

The coming addition, dubbed The Grove, will add another 109,000 square feet of tenant space between 24 Hour Fitness and Jollibee, next to a parking lot that separates the area from the main mall complex anchored by Macy’s, H&M, Consolidated Theatres and a Hampton Inn &Suites hotel.

About half of the new space will be occupied by Foodland and Hawaii Pacific Health.

Roger Wall, CEO of Foodland Super Market Ltd., said the kamaaina grocery store chain had been reluctant about opening a store at Ka Makana because it opened a 36,000-square-foot Foodland store in Kapolei five years ago on land it owns. But looking at how many more homes are slated to be built in the region closer to Ka Makana convinced the company it should be part of what is projected to become the state’s third-largest shopping center after Ala Moana Center and Pearlridge Center.

“The growth in Kapolei has been so dramatic we thought, long term, we probably need another store to support the community here,” Wall said.

The new 35,000-square-foot Foodland Farms is planned to feature prepared fresh foods with a dining area inside the store and on an outdoor lanai, as well as other elements not found at most Foodland stores.

For Hawaii Pacific Health, the clinic is designed to be 16,000 square feet for use by physicians practicing primary care, pediatrics, obstetrics-gynecology and sports medicine. An urgent care department also will be part of the facility expected to employ about 50 people.

“We have always said that we would establish a clinic in Kapolei at the right time and the right place,” said Art Gladstone, CEO of Hawaii Pacific Health’s Pali Momi Medical Center and Straub Clinic &Hospital. “We are very excited that the time is now and this is the right place.”

DeBartolo, which owns Ka Makana with Canadian pension fund management firm OPTrust on land leased from the state Department of Hawaiian Home Lands, does not have an expected timetable to start phase two of the mall, according to English.
