This data set is an aggregation of data from multiple Environmental Sensitivity Index (ESI) maps published by the National Oceanic and Atmospheric Administration (NOAA) which cover the entire shoreline of California. The ESI data were collected, mapped, and digitized to provide environmental data for oil spill planning and response and characterizes coastal environments and wildlife by their sensitivity to spilled oil. This feature includes additional coding to simplify mapping of intertidal classification which was completed in support of Marine Protected Area planning during implementation of the California Marine Life Protection Act. This version includes the most recent ESI versions as of 2023. The last update in source map data was in southern California in 2010.
This feature contains vector lines representing the shoreline and coastal habitats of California. Line segments are classified according to the Environmental Sensitivity Index (ESI) classification system and are a compilation of the ESI data from the most recent ESI atlas publications. The ESI data includes information for three main components: shoreline habitats, sensitive biological resources, and human-use resources. This California dataset contains only the ESI shoreline data layer and is a merged set of individual ESI data sets to cover the entire California coast. For many parts of the California shoreline, the NOAA-ESI database lists several shoreline types present at a given location, described from landward to seaward. A simplified singular classification [Map_Class] was created to generalize the most dominant features of the multiple shore type attributes present in the raw data.

Attributes:
Line: Type of geographic feature (H: Hydrography, P: Pier, S: Shoreline)
Most_sensitive: If multiple shoreline types appear in ESI classification, this field represents the highest value (most sensitive type); otherwise it is the same value as the ESI field.
Shore_code: The ESI shoreline type. In many cases shorelines are ranked with multiple codes, such as "6B/3A" (listed landward to seaward).
Source: Original year of ESI data.
Esi_description: Concatenation of shore type descriptions (listed landward to seaward)
Shoretype_1: Numeric classification for the first (most landward) ESI type.
Shoretype_1_name: Physical description for the first ESI type.
Shoretype_2: Numeric classification for the second ESI type.
Shoretype_2_name: Physical description for the second ESI type
Shoretype_3: Numeric classification for the third (most seaward) ESI type.
Shoretype_3_name: Physical description for the third ESI type.
Map_class: Generalized ESI shoreline type for simplified symbolization.
