The remnants of old creosote-treated piers and dilapidated maritime facilities are common sights along intertidal and subtidal shorelines. Removal of these structures has been proposed as a possible restoration focus for San Francisco Bay. Removal of dilapidated pilings could mitigate the adverse effects of other environmental threats and advance long-term goals for management and restoration of subtidal habitats in San Francisco Bay.
This project included four main tasks:
- Map abandoned creosote-treated pilings throughout San Francisco Bay.
- Assess the potential impacts and benefits of creosote-treated pilings.
- Develop methods for determining potential historic significance, or lack of significance, that might assist in prioritizing structures for removal.
- Assess the methods and actions that would be needed to remove or treat the structures.
The report summarizes the findings of those tasks and also presents a section about the broader picture for artificial substrates in San Francisco Bay.
