the effort

What is the One Arroyo effort?

The Arroyo Seco is Pasadena's great outdoor space, used by millions each year for recreation and enjoyment.  Even though the Arroyo itself has seldom been conceived or designed as one continuous space, from the headwaters in the North to the tributary waters in the South, its natural habitats, resources and historic sites are unlike any other and enthusiastically enjoyed by those who live, work and visit the city.

The One Arroyo effort endeavors to bring awareness to the work by the Arroyo Advisory Group (AAG), and others, to restore the legacy of Pasadena's historic Arroyo Seco and unite all three areas of the Arroyo- Hahamongna, Central Arroyo and Lower Arroyo under a singular vision.
