Work History

Mr. Raabe has thirty-eight years of project management, water resources planning and engineering experience for the San Antonio River Authority and private consulting engineering companies. Mr. Raabe has developed and facilitated multi-entity water resources and environmental projects, scientific studies and inter-local agreements that emphasize regional cooperation and sharing of governmental resources.

Mr. Raabe has been the administrator since 1998 for the Region L Water Planning Group, a 32 member body responsible for developing a 50-year regional water plan for 21 counties in south central Texas. He managed the creation of the Regional Water Resources Development Group, a cooperative purchasing program comprised of thirteen water utilities, that purchases and leases Edwards Aquifer groundwater rights. Mr. Raabe facilitated the creation of the Regional Water Alliance, comprised of 22 water utilities, to implement the water projects in the Region L water plan.

Mr. Raabe managed the development of an ecological dynamic simulation model by Texas Tech University to simulate the response of marsh vegetation in San Antonio Bay to variations in freshwater inflow and salinity. He managed a comprehensive instream flow study of the San Antonio River in conjunction with the Texas Water Development Board, Texas Parks and Wildlife Department and Texas Commission on Environmental Quality that resulted in the establishment of environmental flow standards by the TCEQ. He also managed a study by Texas A&M University on the effect of freshwater inflows on whooping cranes. He initiated a groundwater – surface water interaction study of the lower San Antonio River with the US Geologic Survey and two groundwater districts that provided critical information for the groundwater availability models of the Carrizo-Wilcox and Gulf Coast Aquifers.

Mr. Raabe served as secretary and chair of the Edwards Aquifer Habitat Conservation Plan (HCP) Stakeholder Committee which oversees the implementation of the HCP for the protection of the federally-listed spring species potentially affected by the management of the Edwards Aquifer.

Mr. Raabe led the San Antonio River Authority’s efforts to increase collaboration with the soil and water conservation districts and the agricultural community within the River Authorities jurisdiction.
