Proposition O Water Quality Improvements Project

The Proposition O Water Quality Improvements Project (Project) will be completed concurrently with the Pase del Rio Project and is part of the first project of the newly constituted 100 Acre Partnership to be completed on Taylor Yard.

The Project will include on-site stormwater management by constructing a bioretention as a best management practice that will divert flow from surrounding storm drains and capture and filter stormwater runoff. This project also includes trails, restoration of native habitat, lighting, and interpretive signage.

The long-term goal of this Project is to provide a habitat-focused open space along the Los Angeles River.

Planning for the Proposition O Water Quality Improvements and Paseo del Rio projects, including community engagement, began in 2021.

The City of Los Angeles Bureau of Engineering has hired a design team consisting of Tetra Tech, Oyler Wu Collaborative, Hargreaves Jones, Sustainable Landesign, ProjectLine, Alliance Group Consulting, Calvada, FMF Pandion, and GPA.

MRCA is leading the community engagement process for the entire Paseo del Rio project and has hired Lee Andrews Group.
