First Street Foundation, a nonprofit agency, is making accurate climate change-adjusted flood scores available for every property in the U.S. today. There are government-produced maps showing 8.7 million homes and properties at significant flood risk—and it turns out those may have underestimated the amount of real estate at risk by 67%. Or, in other words, an additional 6 million properties face a significant risk of flood.

Before these individual property scores were available, there was no easy way for your average homeowner or buyer to understand the flood risk associated with specific properties. That’s particularly problematic because climate change is causing flood risk to increase; there are more extreme rain events and coastal flooding than there used to be.

A California dam could fail during an extreme storm and send water flooding into Mojave Desert communities that are home to about 300,000 people, authorities said.

The U.S. Army Corps of Engineers announced that it has changed its risk characterization of the Mojave River Dam from low to high urgency of action.

(TNS) - In Congress, battles are raging over disaster relief spending. Who should get the help? Puerto Rico, still seeking emergency reconstruction money in the wake of 2017 Hurricane Maria (and yes, Puerto Rico is part of the United States and just as deserving of help as, say, North Carolina)? How about Hawaii, where volcanic eruptions have seen molten lava destroy homes, roads and other infrastructure? Nebraska and Iowa, which were inundated by some of the worst flooding in their history? California, trying to rebuild from the most widespread and deadly wildfires the state has ever seen? Or the Florida Panhandle and parts of Georgia, where homes and farms were wiped out by the violent Hurricane Michael last year?

(TNS) — The Warrenton, Ore., Commission plans to develop a new policy to address encroachments on the city's levee system.

A recent inspection of Warrenton's nearly 11 miles of levees revealed several issues. There are moles everywhere and, in several cases, there are structures built into levee slopes.

One example the U.S. Army Corps of Engineers has rated as "unacceptable" is a garage built into the levee right of way off Main Avenue near Fourth Street.

If the garage is not addressed, it could jeopardize the levee system's status within the federal Rehabilitation and Inspection Program, which provides rehabilitation assistance.

A Northern California river flooded 2,000 homes, businesses and other buildings and left two communities virtual islands after days of stormy weather, officials said Wednesday.

The towns of Guerneville and Monte Rio were hardest hit by water pouring from the Russian River, which topped 46 feet on Wednesday, said Briana Khan, a Sonoma County spokeswoman.

(TNS) - One of the winter’s strongest storms brought flooding across Northern California’s wine country Wednesday, with no region hit harder than the town of Guerneville and the Russian River Valley, which has been inundated repeatedly over the decades.

Some 3,600 people in about two dozen communities near the river were evacuated Wednesday by the flooding, which prompted the Sonoma County Board of Supervisors to declare a local emergency. Authorities warned that those who chose to stay in their homes could be stuck there for days.
