FEMA Mitigation Best Practices: Expansive Flood Control Project Safeguards Austin Texas Neighborhood [open pdf - 362KB]
While much of Texas was overwhelmed by torrential rains over the Memorial Day weekend of 2015, residents of an Austin subdivision were spared thanks to a flood mitigation project completed in 2004. [...] The solution consisted of a two-phase project. Phase I focused on improving the drain system, while phase II involved the installation of a levee/floodwall system to protect the neighborhood from creek overflows. The levee/floodwall system incorporated Loyola Lane to create a flood barrier on the southern boundary of the neighborhood. Prior to the improvements, Loyola Lane was five feet below the base flood elevation and could not be reconstructed without the integration of a flood control project."
