Old Marengo Park

A dirt lot that sat barren for 42 years is now a community pocket park, thanks to a collaborative effort spearheaded by the Arroyos & Foothills Conservancy.

Nestled in a residential neighborhood at the intersection of Marengo Avenue and Woodbury Road in Altadena, Old Marengo Park is a community beautification project that demonstrates water-wise gardening techniques. Completed in 2008, the park features native plants and low-water plants, as well as a system that collects and percolates rainwater to replenish the aquifer.

In 2011, Altadena Heritage designated the park an Altadena Heritage Area.


The park’s development was a collaborative effort between a number of community groups, with community members volunteering their time and services. AFC worked with the Altadena Watershed Committee and several other partners to build the park.
