Here is a useful document from the EPA titled FLOOD RESILIENCE; A Basic Guide for Water and Wastewater Utilities (Sept. 2014). This 48 page document is in an unusual, 4-part interactive format. Issued Sept. 2014.
The Diva is curious about how you like the format. Is it worth duplicating for other documents?
Thanks to Don Watson for the link. He describes the format as an instructional slide deck.
Update: thanks to reader John Plodinec for the addition of this related EPA resource: Infrastructure/Water Security Techtools.
