The comment period for the Arroyo Seco Water Reuse Project has closed, and the response has been overwhelming: more than 500 negative comments, over 4,000 petition signers, critical comments from organizations and responsible agencies, and a warning from a Los Angeles City Councilmember. Will Pasadena listen?

An Alternative Proposal from Berkeley

What would San Rafael and San Pascual look like if ecological restoration, cultural stewardship, and long-term watershed resilience became the primary design objectives?

Yuchen Xiong and Max Frieda, two graduate students from UC Berkeley, outlined a conceptual alternative for the San Rafael Confluence and San Pascual Park. Their proposal explores how these sites could shift away from facility-based treatment and toward nature-based hydrologic and ecological processes.

The alternative proposes restoring and naturalizing the San Rafael Confluence while maintaining San Pascual Park as open space for ecological stewardship and community engagement rather than stormwater treatment infrastructure.

Fish in the Arroyo Seco

In June, an angler spotted nine rainbow trout in the Arroyo near downtown Pasadena. And those little fish a bit farther south in the San Pascual wetland? An aquatic expert says they are Arroyo chub, a remarkable native minnow.

The Arroyo is alive!

Trout in the Arroyo — Episode 1

It's not too late to take a stand. Tell Pasadena officials to listen to nature and to community concerns.

We, the undersigned, urge the Pasadena City Council to reject the Arroyo Seco Water Reuse Project as currently proposed and to support only Arroyo Seco projects that meet all three of these standards:

• Nature-based
• Promote biodiversity
• Community-shaped
