Transforming Shorelines Project

About Transforming Shorelines

Funded by EPA Region 9 Water Quality Improvement Fund, the Transforming Shorelines Project is supporting collaborative engagement on nature-based solutions.

Transforming Shorelines will (1) build regional capacity for nature-based solutions through technical support and analyses; (2) advance a suite of NBS projects through design, permitting and implementation, and; (3) advance state of the art water quality improvement approaches at the Oro Loma Horizontal Levee site.

The Transforming Shorelines Collaborative is a hands-on forum for wastewater treatment managers, planners, regulators, designers, and engineers to discuss best practices for nature-based shoreline infrastructure projects that incorporate treated wastewater. 

This next Collaborative workshop will be focused on the ongoing San Leandro Treatment Wetland Project that aims to restore a 4.3- acre wastewater storage basin to create a multi-benefit treatment wetland at the City of San Leandro’s Water Pollution Control Plant (WPCP), and develop a community-based shoreline resiliency and tidal marsh restoration vision for the surrounding area. It will advance the reduction of wastewater-borne contamination and eutrophication via development of new forms of green infrastructure. The San Leandro team will bring their regulatory and design ideas to a panel of experts and hope for an interesting conversation with participants. Join us and bring your ideas!
