Community Street Safety Project

Altadena Town Trail & Greenway Initiative (ATTGI)

What would make your street feel safer to walk or bike on?

Through walks, runs, and bike rides, we’re paying attention to what people experience, what feels unsafe, and what’s missing, and beginning to test small improvements along a pilot corridor in Altadena.


In partnership with Altadena Bicycle Club & Altadena CoLab • Community rides and walks underway • Supported by a national grant

what’s going on?

why this started

Altadena has lost community members, including Tarnie Fulloon Israelsson and Kent Pulver, in pedestrian-vehicle collisions.

In many areas, especially west of Lake Avenue, streets are not safe for walking or biking.

what we’re doing

We’re hosting:

  • community bike rides

  • neighborhood walks

  • local movement-based events

This gives people a chance to notice what feels unsafe and what’s missing.

what this leads to

This can grow into a network of safer,
more connected routes across Altadena - connecting neighborhoods, schools, local businesses, and the foothills.

We’re beginning to test small improvements, such as shade, seating, and wayfinding, along a pilot corridor.

where is this happening?

We’re focusing on areas west of Lake Avenue, where safety concerns are
highest and many streets were not designed with people in mind.

who’s behind this?

Other cities have made changes to their streets that led to measurable improvements in safety.

Safer streets start with what we notice together.
