The Society of Professional Journalists announced today that ProPublica’s “After the Flood” project was a winner in the informational graphics category of its 2013 Sigma Delta Chi Awards for excellence in journalism.

Reported in the wake of Hurricane Sandy, “After the Flood” used stories, interactive maps and news applications to show how Congress and the Federal Emergency Management Agency have fallen catastrophically short in safeguarding the public from rising waters. The winning graphics, by ProPublica’s Al Shaw and Jeff Larson and WNYC’s Robert Lewis, included a map allowing readers to compare New York City’s old and revised flood-risk maps and see how well each predicted the extent and depth of flooding from Hurricane Sandy. The entry won in the category for smaller and online-only publications.
