San Antonio River Basin LID Technical Guidance manual
The San Antonio River Basin Regional Modeling Standards for Hydrology and Hydraulic Modeling
was developed in 2006 in support of regional flood studies that were prepared as part of the
Federal Emergency Management Agency’s (FEMA) Flood Map Modernization (Map Mod) program.
The San Antonio River Authority promotes programs and activities that proactively inform residents and property owners of their potential risk for flooding. By providing the most accurate and up-to-date information on flood risk, the River Authority enhances the ability for governments, businesses and individuals to make informed decisions to manage flood risk and protect life, property and infrastructure from flooding.
