Two pieces of a master plan for redeveloping nine blocks in Kakaako owned by Kamehameha Schools got the go-ahead Wednesday.

The Hawaii Community Development Authority, a state agency governing development in Kakaako, approved two detailed project plans with 6-0 votes by its board after public hearings.

One project approved is called The Collection, a complex featuring 467 condo units, including 397 in a 43-story tower, 54 in a four-story building and 16 three-story townhouses. Retail and restaurant space along with a 914-space parking garage are also part of the plan for the block bordering Ala Moana Boulevard and South, Auahi and Keawe streets where CompUSA once operated a store.

Honolulu-based Alexander & Baldwin Inc. is developing the project on land it has arranged to buy from Kamehameha Schools.

The other piece of the Kamehameha Schools master plan approved is a retail complex dubbed SALT.

The SALT project will provide space for 35 to 50 mostly retail and restaurant tenants just Diamondhead of The Collection on the block bordered by Ala Moana Boulevard and Coral, Keawe and Auahi streets.

Kamehameha Schools envisions seven towers on nine blocks under a master plan approved by HCDA in 2009.

Other pieces of the master plan include three luxury condo towers on adjacent blocks fronting Ala Moana and a moderate-priced tower with 600 units two blocks mauka from The Collection.

Detailed plans for those four tower projects have yet to be submitted to HCDA for approval.
