Kamehameha Schools is moving forward with plans for a third piece of its Kakaako redevelopment master plan that will include a residential tower involving local developer Stanford Carr.

The trust is scheduled to announce the plans Friday.

The project will include a residential tower, townhomes, live-work units, rental apartments and commercial space, Kamehameha Schools said in an announcement Monday.

Other details including the site location were not disclosed.

Kamehameha Schools launched two pieces of its Our Kakaako master plan earlier this year.

The first piece is being developed by local development firm Alexander & Baldwin Inc., which is buying the former site of a CompUSA store at the makai end of South Street from the trust and proposing a tower and low-rise buildings with 470 condominiums.

The second piece is a retail complex with a parking garage dubbed SALT on an adjacent block to The Collection that will be created mostly by renovating old buildings on the site.

Both The Collection and SALT are pending approval by the Hawaii Community Development Authority.

The Our Kakaako master plan covers 29 acres spread over nine blocks, and allows up to 2,750 residential units, seven towers and 300,000 square feet of commercial space.
