Tulsa's Greenwood District is applying for a place on the National Register of Historic Places.
Preservationists say honoring the site of the 1921 race riot with the listing will teach future generations about the riot and the lessons learned since then.
The Greenwood District encompasses about 36 blocks in north Tulsa.
The state's Historic Preservation Office plans to send the application to the National Park Service in October.
The government will have 45 days to consider the nomination.
The public can learn more about the effort at a public meeting at the Greenwood Cultural Center Tuesday evening at 6:00.
