In its latest estimate of Civic Center construction costs, Newport Beach expects to spend as much as $12.5 million more than planned when it approved bonds to cover the project in November.
According to estimates released Monday afternoon, Newport will spend between $124.9 million and $135.5 million — up from $123 million in November.
The final cost will depend on if the City Council approves some options Tuesday, like a bridge connecting two sections of the Civic Center, and if the design and construction teams cut their own spending.
"We're always looking to reduce costs," Public Works Director Steve Badum said on Friday.
The city had already identified more than $4 million in potential savings, according to construction documents, by using less expensive materials and better technologies.
How much could be saved by using solar energy technology is one question the council will consider Tuesday. A solar installation company estimated that the city would reduce its total electricity costs by 25% and the system would pay back costs within about 11 years.
But the initial $750,000 investment in photovoltaic roof panels may be too much, some council members said Monday.
"I'd like to see us do it," said Councilwoman Nancy Gardner, but the building is already very energy-efficient, she added, and the money might be better spent elsewhere.
Another, more expensive, question the council will address is whether a bridge should span San Miguel Drive, linking the City Hall with the dog park and other open space planned for the area near the Newport Transportation Center.
Its price tag: $2 million.
"I'm not leaning in favor of those two items," said Mayor Mike Henn. "They need to be considered in the context of the total spending allowance."
Indeed, the project's total spending is expected to grow when the City Council makes a nearly $90-million appropriation to the budget at Tuesday night's meeting.
