The state’s High Technology Development Corp. is advancing an effort to develop a new $22 million headquarters by handing off planning and design work to another state agency that has agreed to provide land in Kakaako for the building.

The Hawaii Community Development Authority has accepted the planning role for the project envisioned to be part of a technology and innovation complex on a 6-acre site just Ewa of the University of Hawaii John A. Burns School of Medicine.

HCDA owns the parcel and had previously committed to lease it to UH for a cancer research center that was instead developed on an adjacent parcel and opened last year.

A new master plan for the vacant site envisions a regional parking structure with up to 900 stalls, 150,000 square feet of building space for UH, 50,000 square feet for the technology agency and other uses.

The technology agency, which works to grow the high-tech industry in Hawaii, is currently based in Manoa.

In 2012, the Legislature appropriated $3 million for the agency to plan for and design a new facility. The agency spent $275,000 to determine a suitable site and agreed to move to the HCDA property in Kakaako.

On Wednesday, HCDA’s board agreed to accept the balance of the appropriated money to continue design and planning work.

The technology agency plans to request an estimated $22 million for construction during this year’s legislative session.
