A Kerrville-area river authority executed a contract last month for a flood warning system that would’ve been used to help with emergency response, local government officials said in response to a request by ABC News.

"An initial kickoff meeting was scheduled for mid-July," an unidentified spokesperson for the area’s Joint Information Center wrote.

A review of minutes of local government meetings shows that some county commissioners, sheriffs and other leaders have urged improved flood warning systems in the area for decades.

During a meeting on April 17, the Upper Guadalupe River Authority’s Board of Directors unanimously voted to select a company to develop a flood warning system in Kerr County.

The contract was for “a centralized dashboard to support local flood monitoring and emergency response,” which would allow emergency managers to view real-time streamflow and rainfall data all on one platform, according to local officials.

The system would not issue public alerts, but would serve as "a decision-support resource intended to complement existing infrastructure," officials said.

The spokesperson for the Joint Information Center told ABC News, "In light of recent events the timeline [of the new system] will be reevaluated."
