As the 10th anniversary of Hurricane Katrina draws near, the New Orleans community is focusing on the flooding that followed and rebuilding that continues today.

The Riverfront Alliance will host a free gathering where author Roberta Brandes Gratz will discuss her book, “We’re Still Here Ya Bastards: How the People of New Orleans Rebuilt Their City,” at 6:30 p.m. Thursday, Aug. 20, at All Soul’s Episcopal Church, 5500 St. Claude Ave.

Gratz combines journalism and storytelling skills to share stories often ignored by the mainstream media. An urbanist, she resides in New Orleans and New York, and her book focuses on the strength and resilience of the New Orleans community.

New Orleans has moved from recovery and rebuilding into a renaissance period of growth and expansion, Gratz said. Using keen insights and cautionary examples, she examines ways to avoid a fourth word beginning with “R” to the list: regret.

The Riverfront Alliance is a volunteer coalition representing eight neighborhood and community organizations in New Orleans: Algiers Point, French Quarter Citizens, Faubourg Marigny Improvement Association, Holy Cross, Neighbors First for Bywater, Vieux Carre Property Owners and Residents Association, Esplanade Ridge — Treme Civic Association and Louisiana Landmarks.

The organization advocates for preservation of architectural integrity and residential quality of life. For information visit www.riverfrontalliance.org.

Katrina quiz

Founded after Hurricane Katrina, Levees.org recently released a 10-question quiz called the Levee Challenge.

“It’s intended to answer any lingering questions still out there 10 years after Katrina,” said Levees.org founder Sandy Rosenthal. “The Levee Challenge separates the facts from the fairy tale relating to the flooding in New Orleans.”

The free quiz is on Surveymonkey, a cloud-based service company commonly used for surveys and polls but also as an educational tool.

The quiz is designed so that every question has a corresponding response with links to supporting data. The majority of the questions and answers were peer reviewed by four independent academic reviewers.

“Everyone deserves to know the facts about the worst civil engineering disaster in U.S. history,” said civil engineer H.J. Bosworth Jr., senior member of Levees.org. “The Levee Challenge is a great step in that direction.”
