SANTA YNEZ, Calif. -

The Chumash reservation has been approved to expand by 7 acres for a museum and cultural center.

The ruling by the Indian board of Indian appeals is a momentous win in the tribe's 9 year battle against opposing organizations.

They bought the land right across Highway 246 from the casino 2005. But opponents prevented it from becoming federally recognized as part of the reservation.

The land now becomes Chumash reservation in less than 30 days but tribal chairman Vincent Armenta says he is still prepared to fight.

Our reporter contacted the opposition groups like Preservation of Los Olivos and the Santa Ynez valley Concerned Citizens and they did not return her calls.
