There is still debris on the edges of the construction zone and some old sewer pipes that must be removed. But, Sacramento Kings President Chris Granger says the building site is clear.

The City of Sacramento says the project will have created 11-thousand jobs by the time it is complete.
Jonathan Padron with Turner Construction says he's excited to be a part of it.
"It's something actually to be proud of, to be a part of. It's actually something that I've been looking for for awhile. Our company's been talking about it, and we had our doubts as to if it was actually going to happen. I'm actually glad it actually came all together."
The City says the project will cost $477 million to build.
The City of Sacramento will pay $223 million up front by issuing bonds for the project.
Financing and the California Environmental Quality Act were used by opponents this summer as the basis for lawsuits against the project. All have failed to achieve the delays opponents had sought.
Developers plan to begin renovating the remaining portion of the Downtown Plaza once the existing tenants have left. The Kings declined to renew their leases.
Tonight, the Kings open the 2014-15 NBA season at Sleep Train Arena against the Golden State Warriors.
