OCEAN MASK
<DIV STYLE="text-align:Left;"><DIV><P><SPAN>This dataset represents the ocean mask polygon feature class used to define the marine boundary area adjacent to the City of San Marcos region. The layer delineates open ocean areas excluded from terrestrial hydrologic and watershed analyses, providing spatial context for hydrologic modeling, mapping, and visualization.</SPAN></P></DIV></DIV>
The purpose of the ocean mask dataset is to provide a spatial reference boundary for coastal hydrology and watershed modeling. It defines the extent of non-land (oceanic) areas to support hydrologic and geospatial analyses conducted by the City of San Marcos.

Summary: The Ocean Mask dataset defines the open ocean area along the San Marcos coastal boundary, serving as an exclusion zone for hydrologic modeling. It helps differentiate terrestrial hydrology features from marine extents, ensuring accurate coastal watershed delineations.
Description: The Ocean Mask feature class was created for hydrologic, watershed, and stormwater analyses. It is used in conjunction with watershed, drainage, and stream datasets to support spatial modeling and map production. Projection: NAD83 / StatePlane California VI (EPSG:2230).
