LOCKPORT – Ground will be broken about Dec. 1 for the next phase of Yahoo’s Lockport data center after the final approval of the site plan Tuesday by the Town of Lockport Planning Board.

Paul Bonaro, director of the facility in the town industrial park off Junction Road, said the second phase will be constructed with an occupancy capacity of 300, although the company is committing to provide only 115 jobs. The existing data center employs about 90 people.

The next phase will take about a year to build, Bonaro said. There will be a second portion of the expansion at a future date, including half of the planned administration and call center, and a second computer pod.

However, the project beginning in December will include all the drainage ponds needed for both halves of the expansion. Only the emergency generators for the first half will be installed, Bonaro said.

Town Economic Development Director David R. Kinyon said Yahoo won’t need a new tax abatement for the second half of the expansion, but it may need to renegotiate its state incentive package.
