Dozens of people packed the Hawaii Community Development Authority's office in Kaka'ako to find out the fate of a proposed second high-rise at 801 South Street.
The agency's executive director began the meeting by defending the project.
"Give the importance of the comments, I will go through each one of these concerns," said HCDA Executive Director Anthony Ching.
One of the concerns is the affordability of Tower B. Its 410 units are expected to cost from $329,000 to $692,000.
Many of the project's opponents live in neighboring Royal Capitol Plaza, including Ariel Salinas.
"I've gone through the numbers and I can conclusively demonstrate that the numbers that the HCDA using, are using, are factually wrong," said Salinas. "They are simply incorrect."
Critics say the condos at 801 South Street will be too expensive for working-class people, even though the development is billed as workforce housing.
Realtor Jason Nishikawa says workforce housing is for families making between 100 and 140 percent of a community's median income.
"I think he has some of his numbers confused and I think if you look at the incomes that are used, that are allowed to be used under the formula, you will see that it all fits right into this price range that this building is priced at," said Nishikawa.
"If you do an honest analysis and uyou use the, the subject at hands, Tower B, the prices that are listed in the developer's sales packet and their permit packet, you'll see that the sales price is, virtually the entire building, none of it's affordable for any families making up to 140 percent of the area median income," said Salinas.
The HCDA approved construction on the 46-story tower with a 10-story parking garage on Wednesday. The vote was six in favor of the proposal and one abstention.
Construciton on Tower A is already underway. Construction on Tower B is scheduled to begin in 2015.
