This bill proposes an amendment to the Long-Term Leasing Act of 1955 , specifically targeting land within the Mashpee Wampanoag Tribe Reservation and land held in trust for the Wampanoag Tribe of Gay Head (Aquinnah) . The primary objective is to authorize these tribal entities to enter into leases for their lands for a duration of up to 99 years . This legislative change would integrate these specific tribal lands into the existing framework that permits extended leasing periods. Currently, the Long-Term Leasing Act allows for leases of varying durations, but extending the maximum term to 99 years provides significant benefits. Such extended lease terms can facilitate more substantial economic development, housing projects, and infrastructure investments on tribal lands. By granting this authority, the bill aims to empower these tribes with greater control and flexibility over the long-term planning and utilization of their trust lands.
