Renew SF Bay plans to create a sustainable habitat for native oysters and eelgrass on Operational Landscape Unit 28 (OLU28) focusing on three areas of the shoreline that work together to create a suitable environment for the restoration process. The subtidal, intertidal, and upland zones each have unique attributes that need to be considered in the restoration process. Sierra Point Shell Beach is the initial target site for restoration located East of Rt 101 near the Brisbane Lagoon.

OPERATIONAL LANDSCAPE UNITS

​In California, Operational Landscape Units (OLUs) are mapped to represent distinct coastal and estuarine landscapes that share common physical, ecological, and management characteristics. These units help guide regional planning and restoration efforts by organizing the coastline into manageable, place-based segments. The map we are showing highlights the boundaries and distribution of these OLUs, with particular attention to OLU 28. This unit is significant because it is the location of our current project, aligning with regional landscape characteristics and offering a strategic setting for focused planning and implementation.

​YOSEMITE-VISITACION OLU28

Renew SF Bay aims to restore a shoreline in Brisbane California at Sierra Point Shell Beach, within OLU28. We aim to restore the beach's rich biodiversity, which is habitated by many different species in its three marine ecological zones.

The key difference between subtidal, intertidal and upland zones lies in their exposure to air and water. Intertidal zones are periodically exposed by the tides, meaning they alternate between being underwater and above the water line. Subtidal zones, on the other hand, are always submerged and rarely exposed, even during very low tides. And, the upland zone lies above the ordinary high tide line.
