a historic map with historic water features labelled
and a present day map with current water features
and infrastructure labelled.
The LOS and flood resilience framework call for
the integration of grey infrastructure (e.g. upsized
pipes and pumps) with green infrastructure (e.g. rain
gardens, permeable pavement, detention basins) to
address the aforementioned improvements, where
feasible. Watershed Storytellers – Features video interviews
of San Franciscans in their watersheds, sharing their
watershed story. Interviewees share their community
perspective on the unique characteristics of their
watershed, how it has changed over the years

stormwater management.
In 2018 the San Francisco Discover Your Watershed
Project was launched for the public to learn about
San Francisco’s historic watersheds and waterways,
the eight urban watersheds of today, and existing
infrastructure that moves sewage and stormwater
throughout the City. The project
includes place making signage in each
watershed, online interactive maps
and the watershed storytellers video
series. The project helps educate the
public on the historic water features of
San Francisco and how they connect
to our combined sewer system today.
The public can also learn about their
watershed and see how improvement
projects help protect public health
and the environment through green
and grey infrastructure. Visit sfwater.
