Altadena Triangle Park

A park re-made by community

Altadena Triangle Park truly represents the Emerald Necklace Group|AMIGOS vision for sustainable park design that celebrates our cultural heritage and greens our communities. The project is the first in a suite we hope to see come to life for Altadena. It is the result of funding from the Los Angeles County and Open Space District.

A sense of history

” Many working on the $1 million park renovation — reborn as Altadena Triangle Park and located on the southwest corner of Lake Avenue and Altadena Drive — call the unusual memorial a celebration of the community’s inclusive spirit, as well as an homage to both Altadena and Pasadena’s strong abolitionist stands dating back to pre- and post-Civil War times. “ –Pasadena Star News

Storm Water Management 

Bioswales are landscape elements designed to remove debris and pollution out of surface runoff water. They consist of a swaled drainage course with gently sloped sides  and filled with vegetation, compost. Bio swales were included in the park to absorb storm water into the soil and help direct water flow maximizing the time water spends in the swale, which aids the collection and removal of pollutants, silt and debris, and is beneficial in groundwater recharge.
