  1. Stormwater Management - TBD Precipitation - TBD

  2. Rainfall Future projections Topics for Stationarity Today ' s Design Storm Frequencies Multiple design storms Discussion Drainage area Project type Criticality Tailwater Elevations Sea level rise Levels for individual water bodies Compound Flooding Joint probability pairs

  3. Should we use observational Questions for data only or use climate projections ? Precipitation Levels What time horizon should we apply to stormwater management ? What emissions scenario should we use ?

  4. Should we require larger or Questions for more important projects to perform better ? Design Storm Frequencies Should different standards be based on drainage area ? Criticality ? Something else ?

  5. Should we establish Questions for elevations for individual water bodies ? Design Tailwater Should design tidal elevations factor in sea level Elevations rise ? How much ?

  6. Should we use joint Questions for probability events ? Compound Flooding How many combinations should include ? Which ones ?
