Texas county commissioners previously suggested "river calling," an informal phone chain used by summer camps, would be better than installing new flood sirens.

Kerr County and the Upper Guadalupe River Authority have tried several times to get funding to upgrade flood alerts on the river, dating back to 2016.

A former official from Kerr County Texas, said that the community was not in favour of putting up outdoor emergency sirens in 2017 and that the federal grant for them failed to be approved due to a lack of funding.
