 Idlewild became a lesser-known family vacation and retirement community, primarily attracting retirees who remembered it from its boom period.In the 1970s township officials organized a planning commission, zoning board, and other initiatives as a way to encourage community input and to offer specific practical solutions to improve the community.Community Development Block Grants (CDBG) were obtained for demolition, additional roadwork, and other structural changes, which resulted in a complete makeover of the island, renamed "Williams Island" in honor of early community leader Dr. Daniel Hale Williams.
