Help us restore the beauty of these historic natural spaces.
Because we’re all in this together.


The 1960s were a time of transformation, enlightenment — and revolution. Out with the old, in with the new. During this time of rapid change, leaders in Portland were looking for ways to bring nature back to the heart of the city. Enter Lawrence Halprin – a renowned landscape architect with profound new ideas about how people and parks come together. This revolutionary approach gave life to an urban oasis of interconnected downtown blocks and plazas.

Today, these visionary parks are in disrepair and need your help. As we close in on the 50th anniversary of these heritage spaces, we need your help to restore them to their former glory.

Learn more about the Portland Open Space Sequence, its significance and how you can be part of the future.
