The hamlet is a key point on the Cattaraugus Indian Reservation; the Seneca nation's governmental headquarters for the reservation are located in Irving. Irving rotates as the capital of the Seneca nation with Jimerson Town on the Allegany Reservation every two years; its current run as capital will end in November 2014. Several tax-free gasoline stations and smoke shops are located in the hamlet, as is Seneca Gaming and Entertainment, a Seneca-owned bingo hall.
Another small community, Sunset Bay, is located near Irving. Sunset Bay frequently floods during unseasonably warm winter days because of ice jams that form in the nearby Cattaraugus Creek as a result of melting water in the stream.
