Codornices Creek

Codornices Creek is a perennial stream that flows from the headwaters in the Berkeley Hills west to the San Francisco Bay. The creek is an important fish run, providing habitat for native Steelhead Trout, as it is one of the most open creek tributaries to the San Francisco Bay. The Codornices Watershed encompasses about 700 acres, extending east to the ridge of the Berkeley Hills. Thirty acres (or about 4%) of the watershed are within Albany.

East of Highway 80, Codornices Creek forms the boundary between the cities of Berkeley and Albany.

History

Albany's five creeks are an important feature of the City's natural landscape. Planning efforts for creek restoration and habitat repair in Albany date to the 1990's. In 1998, Albany completed a Watershed Management Plan, which identified opportunities for creek restoration in Albany.

Concurrent with the development of this Management Plan, the City of Albany, the City of Berkeley, and the University of California began planning for the multi-faceted restoration of Lower Codornices Creek. This creek segment runs from San Pablo Ave west to the Union Pacific Railroad tracks and flows through land belonging to all three agencies.

In 2001, the Lower Codornices Creek Improvement Plan was prepared, which included proposed methods for habitat restoration and construction of trail along this reach of the creek. In 2004, Albany, Berkeley and the UC entered into a Memorandum of Understanding (MOU), which would move forward implementation of improvement measures and establish ongoing maintenance practices along Lower Codornices Creek.

Four phases of the Lower Codornices Creek Restoration Project have been completed to date, including a bicycle-pedestrian shared use trail. Restoration projects provide recreational, educational and stewardship opportunities, as well as restoring habitat to native Steelhead Trout, and improving community resilience by reducing exposure to flooding at UC Village student housing. In 2010, the first phases of restoration of Codornices Creek won the ABAG Growing Smarter Together Award in the category of "Protecting and Preserving the Environment" for advancing smart or "focused" growth in the Bay Area.

Restoration Plans

The Phase 4 Project, completed in 2024, included a bicycle and pedestrian shared-use path from 8th to 10th Streets, a crossing at 8th street to link to the Phase 3 project, and minor vegetation improvements. Phase 4 was funded as part of Alameda County Transportation Commission's 2022 Capital Investment Plan, and was the recipient of $826,000 in Measure B and TFCA grant funding. Matching funds for the grant were provided from local Measure R funding for creek restoration. The Phase 4 project was completed in 2024.

Future Phases of the Lower Codornices Creek Restoration Project address the remaining unrestored sections of the creek. The conceptual plan for Phase 5, between San Pablo and 10^th Street, includes removal of a culvert underneath 10^th Street, construction of a pedestrian bridge to maintain pedestrian and bicycle access from Albany to Berkeley on 10^th Street, and a full ecological creek restoration project in the creek channel. The planning effort required for the Phase 5 project is currently in process.

Codornices Creek Maintenance

Staff from Albany, Berkeley, and UC Berkeley meet on a regular basis to review and implement the maintenance requirements of the MOU. These requirements include creek monitoring, trail and landscape maintenance, and culvert and bridge maintenance. The MOU also established a Creek Maintenance Account, administered by Albany, usage of which is restricted to maintenance activities such as vegetation management, improving signage, and monitoring ecological activity. Per the MOU, all three agencies are assigned maintenance responsibilities and contribute to the Creek Maintenance Account.
