§ 13.3.2.2. Design Frequencies

Latest version.

The City of San Antonio restricts the outflow rates to the undeveloped or existing five (5) year, twenty-five (25) year, and one hundred (100) year frequencies, 24 hour storm. The designed basin should not increase flood elevations upstream of the new development. See Chapter 5 "Hydrology" for approved methods of developing flows for the needed frequencies.
