The Problem

Sunny-day tidal flooding in Charleston is predicted to occur up to 180 days a year by 2040 and 75 percent of residents live in a designated flood zone, making it essential that the city learn to adapt to and coexist with water.

The Idea

The City of Charleston will develop a first-ever emergency alert system to prepare residents, businesses, and first responders with specifically tailored information about increasingly routine coastal floods.


What Mayor John Tecklenburg is saying:

The concept of a flood-notification system fits squarely within our ongoing flooding and drainage improvement efforts—and could be an invaluable tool for communicating risk with our citizens moving forward.

Our Prototyping Journey

    Let's Go

  • How we are testing our idea

    Charleston is testing the information and interface that residents will use by creating a clickable “app” that simulates their alert system, engaging residents along the way through user group events and surveys.

  • Ideas into action

  • One thing we’re discovering through testing

    The Charleston team has learned the value of immersing residents in the appropriate frame of mind in order to gain richer insights. Since testing is taking place during the City’s dry season, the team has found it difficult to engage residents to test the flood alert system. To counter this, they have been asking residents to recount their most recent flood situations to ground them in the problem and get them in the right mindset for the rest of the interview.
