The Cibolo Creek study area is approximately 854 square miles. This Risk MAP project will leverage previously developed DFIRM hydraulic models, 2009/2010 LiDAR data, and 2013 LiDAR data to produce additional flood risk data products for an estimated 350 stream miles. This study area extends from Bandera County down into Bexar County where it confluences with the San Antonio River. The Medina River study area is approximately 1,348 square miles and is comprised of 2 major sub-watersheds, the Medina River Watershed and the Leon Creek Watershed. This Risk MAP project will seek to leverage previously developed DFIRM hydraulic models and 2009/2010 LiDAR data to produce additional flood depth and flood risk data products for approximately 250 stream miles. Both of these major sub-watersheds are predominately located within Bexar County. The Upper San Antonio study area is approximately 507 square miles and is comprised of 2 major sub-watersheds, the Upper San Antonio River Watershed and the Salado Creek Watershed. Each project includes three phases: “Discovery,” “Risk Identification and Assessment,” and “Regulatory Product Update.” These projects are supported by a combination of FEMA grant funding and SARA local match dollars and in-kind services. These are the Upper San Antonio River, the Medina River, Cibolo Creek, and Lower San Antonio River. Projects are underway in each of the four major watersheds in the San Antonio River Basin.
