Representatives of dozens of groups working to improve the Arroyo Seco region have formed a important organizational forum — CASO, the Council of Arroyo Seco Organizations
CASO — the Council of Arroyo Seco Organizations — is a dynamic forum for organizations working to make a difference in the quality of life in the Arroyo Seco area through issues such as transportation, environment, outdoor recreation, historic preservation, education, and many more.
Many Arroyo Seco organizations have been working together for many years on improving the parkway, saving the Southwest Museum, and restoring the watershed. CASO held its first meeting in May 2004 and has been meeting quarterly since then. The meetings include featured presentations on key topics affecting the Arroyo Seco region and reports from participating organizations on their activities. The sessions are always informative and lively.
The purpose of the Council of Arroyo Seco Organizations is to promote communication and cooperation between community-based organizations working to improve and enhance the Arroyo Seco region from the San Gabriel Mountains to the confluence with the Los Angeles River. CASO aspires to cultivate a sense of place that defines this unique region by addressing such issues as the environment, transportation, history, recreation, culture and economic resources.
Hahamongna is the most precious water and environmental resource in our region. Located at the foot of the San Gabriel Mountains as the Arroyo Seco stream enters the urban plain of Southern California, Hahamongna contains five unique habitat zones and unmatched water resources. It's value to habitat, wildlife and people is unparalleled. It cannot be recreated.
