SGV Greenway Network: Creating an Active Transportation Superhighway by 2030

A map of the San Gabriel Valley showing the "Plan Study Area" for the SGV Greenway Network. Dark blue lines trace major waterways including the San Gabriel River, Rio Hondo, and various washes (Eaton, Santa Anita, Big Dalton, San Jose Creek, and others), surrounded by a blue cross-hatched buffer zone indicating the study area. Pink lines delineate Los Angeles County Supervisorial District boundaries overlaid on the regional street and freeway grid.
A map of the proposed San Gabriel Valley (SGV) Greenway Network, illustrating the extensive system of waterways—such as the San Gabriel River, Rio Hondo, and their tributaries—targeted for regional connectivity and improvement. The full Strategic Implementation Plan and the Program Environmental Impact Report (PEIR) are available here.

The San Gabriel Valley is crisscrossed with storm channels, washes and creeks that feed into the San Gabriel and Rio Hondo Rivers. Flanked by gravel service roads, most of these tributaries are ideally suited for Class I Multi-Use Bicycle and Pedestrian Paths, providing a golden opportunity to develop a regional network of protected bicycle and pedestrian infrastructure.

A few of these waterways such as the Eaton Wash, San Jose Creek and Big Dalton Creek have already been identified by County and City officials for such infrastructure. But many others exist! Each would connect new neighborhoods, schools and entire communities to a regional network of protected pathways for safe recreation and healthy, active transportation. 

Driven by the input of community members and stakeholders like you, ActiveSGV launched the 2030 SGV Greenway Network initiative in 2014, setting a goal of 50 miles of new #SGVgreenways and green streets in a decade. 

Please join us in championing a healthier, greener, and more livable San Gabriel Valley by formally endorsing the San Gabriel Valley Regional Greenway Network Initiative!

Existing Waterway Paths

In the foreground, a smiling woman wears a helmet and rides a white electric bike with a front basket labeled "ActiveSGV." Behind her, a man in a blue jersey rides a road bike, followed by several other cyclists in the distance. To the left, high-voltage power lines run parallel to the path, and in the background, snow-capped mountains rise behind a row of industrial buildings.
