BROOKLYN - It's decision day for the future of the old Domino Sugar factory site. 

The City Council approved a deal that will allow developer Two Trees Management to construct residential towers as high as 55 stories in place of the former Williamsburg refinery. 

The buildings would be 15 stories higher than any others along the Brooklyn waterfront, and the developer would agree to certain requirements to include affordable units. 

Construction is expected to take between six and eight years, and Two Trees Management says it’s hired the same architects who designed the Barclays Center. 

The city's land use committee has already signed off on the deal, making the City Council vote the final hurdle before work can get underway.
