How do I map my own data?

Using the San Antonio River Authority Internet Mapping Service, anyone can print out a map containing aerial photographs, watersheds, streets, etc. As the user zooms into an area of interest, more data layers become available for viewing.

How can I view assessor records online?

Assessor records are available at the Bexar County Tax Assessor.

Do I live in a FEMA (Federal Emergency Management Agency) Flood Zone?

Using the San Antonio River Authority Internet Mapping Service, anyone in the Authority District can zoom into their neighborhood and display FEMA Flood Zones. By identifying the flood zone, one can determine if they are in the 100 year flood. Users must understand that the flood maps were derived from national data sources at very small map scales. Thus, actual flood zone boundaries can only be determined through approved site surveys. http://cip.sara-tx.org/website/cip
