Progress on redevelopment was slow, but in early 2006, Governor George Pataki and Mayor Michael Bloomberg launched a competition for ideas to preserve Governors Island. During this period, the National Park Service and GIPEC began conducting restorations on parts of Governors Island. Major construction was necessary to convert the island for public use, such as repairs to the seawall and removal of asbestos. By 2006, the GIPEC had awarded leases to its first two tenants. The public was first allowed to visit the island in 2005, and eight thousand visitors came that year. At first, Governors Island was only open during summer weekends, except for a few concerts. Bikes and ferry services were made free in order to attract visitors. Art exhibits were later added.
