The U.S. is nominating the San Antonio Missions, as well as the Alamo, for inclusion on the World Heritage List, Secretary of the Interior Sally Jewell announced Friday afternoon.

The nomination will be considered for inscription on the World Heritage List by the United Nations Educational Scientific Cultural Organizations in 2015.

"I was very excited and pleased to hear this news. This is huge step forward," said Judge Nelson Wolff. "The San Antonio Missions anchor community events, offer a connected experience for out-of-town visitors and bring an important chapter of our American history to life."

If approved, the San Antonio Missions would join 21 other United States sites already inscribed on the World Heritage List.

U.S. sites include Yellowstone National Park in Wyoming, the Statue of Liberty in New York, Everglades National Park in Florida and the Grand Canyon in Arizona, officials said.

"World Heritage Sites draw visitors from around the world, providing not only prestige to local communities but also a boost to their economies," Jewell said in a statement.

A 2012 Bexar County study found that the designation could provide more than $100 million in additional economic impact, more than 1,000 new jobs and more than $2 million in new hotel tax revenue.

Additionally, officials said Congress recently approved funding for the San Antonio Missions to acquire 40 acres of land that would comprise the last remaining piece of the Mission San Juan farmlands that contain remnants of the San Juan Acequia.
