Sunset Rain Gardens
The Sunset rain gardens were
constructed as part of the City’s
mission to transform San Francisco’s
hardscape into planted and permeable
landscape. The rain gardens divert
stormwater from the street into
landscaped areas in order to reduce the
amount of water going to treatment
plants. Rainwater is collected from the
street via catch basins and piped into
garden areas that have been lined with
a special soil mix, allowing water to
percolate at a predetermined flow rate.
