The deadly Texas floods have brought the state's approach to land approvals, especially in flood-prone areas, under more scrutiny.
Kerr County had discussed buying such things as water gauges and sirens after previous flood disasters. But as with many rural Texas counties, cost was an issue.
The data also highlights critical risks in other areas along the Guadalupe River in Kerr County, revealing more than twice as many Americans live in flood prone areas than FEMA's maps show.
The risk of the catastrophic flooding that struck Texas Hill Country as people slept on July 4 and left at least 120 dead was potentially underestimated by federal authorities, according to an ABC News analysis of Federal Emergency Management Agency data, satellite imagery and risk modeling.
Kerr County repeatedly failed to secure a warning system, even as local officials remained aware of the risks and as billions of dollars were available for similar projects.
