Climate change may induce increases in precipitation magnitude, storm surge, and/or sea level rise, resulting in increased Pacific Ocean and San Francisco Bay water levels. These three variables, individually or in combination, may cause stormwater systems to not perform up to levels of service standard.
Larger magnitude rainfall, in concert with higher Pacific Ocean and San Francisco Bay water levels, has the potential to constrain the ability of systems to discharge through outfalls, resulting in upstream flooding. Furthermore, building or increasing the presence of shoreline flood protection structures along the City’s periphery to protect near shore areas against rising water levels may exacerbate the severity of inland flooding.
