"We don’t have to wait for people to call and tell us there’s a problem. We’ll know there’s water over the roadway. We can react. We can issue advisories from the EM center, public works, all the things that need to happen when that occurs."​

​

June 4, 2025

"The path forward is clear. Public-private partnerships, local knowledge and initiatives, and improved sensor networks will provide the data we need to better predict, prepare for, and respond to storms. By working together, we can build stronger, more resilient communities that are equipped to face the challenges ahead."​

​

"Our fundamental dependence on water in a changing climate has made managing water resources—both too much and too little of it—increasingly difficult. Flood risks are the undisputed headliner here. Companies like Fathom and First Street are rolling out solutions for better flood prediction, and Floodbase and Hohonu are among those working on flood monitoring."​

​

August 15, 2024

"Hohonu has launched dozens of community projects proving this model with emergency management professionals in Maine, Washington, Hawaii, Florida, North Carolina and Texas, to name a few."​

​

August 13, 2024

"That fundamental catch-22 — that the infrastructure designed to mitigate climate change is itself vulnerable to the extreme weather events that a changing climate makes worse — is at the root of the philosophy of adaptation technology. And at long last, that tech is having a moment."​

​

August 8, 2024

"The move to bring data to the public and communities marks a significant step towards better flood preparedness and resilience. As coastal communities continue to face the challenges of rising sea levels and more frequent storms, the real-time data provided by these sensors will be invaluable in informing strategies and protecting vulnerable areas."

“What this provides for our first responders is more accessibility and ability to actually respond in real time, as opposed to waiting for the problem to reach the point where our residents are saying, ‘Look, we can’t even get out of our homes, or we can’t get back in our homes,'” Collins said. “We see this directly. We see the impact of what climate change is actually doing to our community.”​

Being on a barrier island and susceptible to tidal flooding and storm surges places the residents, businesses, and property in Fernandina Beach at great risk to the danger of rising ocean waters.

​

March 4, 2022

Dr. Brian Glazer explains that extreme weather events are generally forecast for large areas, sometimes multiple states and regions. Many small municipalities don’t have access to updated emergency flood zone mapping or effective monitoring of levies, waterways and drainage systems.

​

March 1, 2022

We can’t afford to continue working with the regional level of detail we have now. For us to have locally accurate storm surge and tidal flooding models that are meaningful to everyone in the Tampa Bay area, we need more data at greater resolution.

​

January 20, 2022

Coastal communities need accurate, reliable, and accessible information on tides, particularly as they confront rising sea levels and need to adapt to flooding events. But federal gauges are spread out on the U.S. coastline, which leaves extensive areas in between without precise predictions and real-world tracking of tides.
