Sea Level Rise Coastal Erosion Mapping

Data: Sea Level Rise Coastal Erosion Mapping

Abstract:

This dataset includes: The locations of EPA listed sites that are vulnerable to a 100-year coastal flood with a 1.4 meter sea-level rise. Extents of dune and bluff erosion given a 1.4 meter (approx. 55") sea-level rise for the entire California coast. Extent of a 100-year coastal flood, based on FEMA 100-year flood elevations, with a sea-level rise of 1.4 meters (55 inches) (year 2100). Extent of inundation due to Mean Higher High Water (MHHW), after a 1.4 meter sea-level rise (scenario for year 2100), for the California coast (excluding the San Francisco Bay). The current inundation due to MHHW was based on NOAA tide stations elevation data (mhhw_2000 raster), to which 140 centimeters were added to the Z-value to generate this data. For details concerning methods, see the OPC SEA LEVEL RISE COASTAL EROSION MAPPING document from Philip Williams and Associates, LTD, from December 18th, 2008.

Applying ecological principles

Ecological principles represent the core attributes of natural systems that must be maintained or restored in order to support healthy marine and coastal ecosystems, and include maintaining, restoring, or accounting for:

These principles are explained in a reference guide for agencies in California, called the Ecological Principles Guide . This guide also includes a series of case studies and checklists that demonstrate how the principles can be applied to day-to-day decision making.

State GeoPortal

The EcoPrinciples Connect tool links to data from the California Geoportal, which offers an easy and convenient way to search, discover and use authoritative geospatial data resources. This one-stop geospatial shop is helping to improve access to California’s geographic data portfolio and expand the use of those data resources in decision making processes.
