New condominium towers in Kaka­ako would be spaced farther apart and be built no higher than existing towers under bills that were advanced Tuesday by the House Committee on Water and Land.  But the committee deferred a one-year moratorium on development in the area. The committee revised and passed four of seven bills affecting the Hawaii Community Development Authority, the state agency governing development in Kaka­ako, after a Saturday hearing that attracted nearly seven hours of public testimony. HCDA has defended its procedures and decisions, after much criticism. The most drastic of the HCDA reform bills would have killed the agency, but that was deferred.    The HCDA-related bills now head to the House Finance Committee. No hearing has been scheduled yet.  If the bills pass that committee, they would cross over to the Senate.
