Ala Moana Center’s owner will sign a second major anchor for the redeveloped Ewa end of the mall soon and add 1,000 new parking stalls as part of the project to be completed in 2015.

Owner General Growth Properties Inc. said Tuesday it expects to have a deal with an undisclosed retailer in as early as two months as part of a $572.4 million three-level expansion project. Famed New York retailer Bloomingdale’s has taken one of the two anchor spots and will open its first Hawaii store when the mall addition is finished in November 2015, General Growth officials said in an interview with the Star-Advertiser.

Bloomingdale’s will occupy a three-level space to be built on the parking area fronting the now-vacant Sears store.

The center also will begin construction next month to add four more levels on top of the existing four-story mauka-Ewa parking structure parallel to Kona Street.

“Ala Moana has experienced a number of significant expansions since it first came into existence during statehood in 1959,” said David Cuthill, General Growth’s vice president of development. “Ala Moana has consistently shown it can absorb expansion projects. Right now the economy is tracking well, and we are confident that this will be a great success.”

In addition to the two anchor stores, the project will add 200,000 square feet of space for smaller tenants. The former Sears building will be demolished by year’s end. Construction is expected to create more than 1,000 jobs.

“Everything we’re doing is going to be brand new from the ground up. There’s going to be a variety of stores, new brands that aren’t currently in Hawaii,” said Scott Creel, Ala Moana’s senior marketing manager. “We’ve got a list of tenants that would like to be here today, and we cannot accommodate them because we physically don’t have the space.”

Ala Moana has temporarily closed off 2,000 of its 10,000 parking stalls for construction. Parking will increase by roughly 10 percent, or by 1,000, when the garage project is completed in early 2015. It also will reopen closed parking ramps to the mall.

Separately, Howard Hughes Corp., which owns the nearby Ward Centers, is building a 23-story luxury residential tower atop the Nordstrom department store parking garage, which has displaced an additional 440 stalls in the upper two levels of the garage. That project is slated to be completed in November 2014.

As the holiday season approaches, the Ala Moana Center will scale back construction, opening displaced parking stalls for shoppers, then resume building at the start of the year.

“There’s going to be long periods of time where things will settle down and there will be nothing that will interrupt (customers’) ability to access the center,” Creel said. “As we move into a new phase, there will be some changes that are just part of the process, and we will inform the public in advance of what they might expect.”

The expansion allows General Growth to unlock the value of the prime real estate at the Ewa end of the complex and substantially increase revenue for the center between the bustling Waikiki tourism district and growing residential community in Kakaako.

Ala Moana, with 290 stores and 2.1 million square feet of retail space, will expand to roughly 2.4 million square feet. Creel said the number of retailers to be added is still undetermined.

The mall, which attracts 42 million shoppers annually and generates sales in excess of $1,400 per square foot, also is reconfiguring Centerstage and upgrading the surrounding street-level shops.

The first phase of the street-level renovation project is open, including expanded restrooms, renovated common areas and new stores. The second phase will open in November and will include the new Centerstage, customer service area and additional tenant spaces.
