The goal of this project is to quantify, at the National scale, the relative susceptibility of the Nation's coast to sea- level rise through the use of a coastal vulnerability index (CVI). This initial classification is based upon the variables coastal geomorphology, regional coastal slope, tidal range, wave height, historical rates of relative sea-level rise and shoreline erosion and accretion rates. The combination of these variables furnishes a broad overview of regions where physical changes are likely to occur due to sea-level rise. Data downloads available at http://pubs.usgs.gov/dds/dds68/
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...
The points depicted are attributed the highest estimated 100-year tide elevation for locations surrounding the San Francisco Bay.
Sandy ocean beaches are a popular recreational destination, often surrounded by communities containing valuable real estate. Development is on the rise despite the fact that coastal infrastructure is subjected to flooding and erosion. As a result, there is an increased demand for accurate information regarding past and present shoreline changes. To meet these national needs, the Coastal and Marine Geology Program of the U.S. Geological Survey (USGS) is compiling existing reliable historical shoreline data along open-ocean sandy shores of the conterminous United States and parts of Alaska and Hawaii under the National Assessment of Shoreline Change project.There is no widely accepted standard for analyzing shoreline...

The polygon represents the extent of inundation due to Mean Higher High Water (MHHW) under current conditions (year 2000) based on NOAA tide stations tide elevation data.
The Base Flood Elevation, representing the elevation of the 100-year coastal flood, is derived for the entire California coastline. Data is in NAVD88, rounded to the nearest half foot.
This dataset shows police stations that are vulnerable to a 100-year coastal flood event with a 1.4 meter sea-level rise in California (year 2100 scenario). The police station data was extracted from the FEMA HAZUS model and was intersected with the flooding layers created by the Pacific Institute and USGS/SCRIPPS.
This file includes only healthcare facilities in California which are located within the areas that would be inundated by a 100-year coastal flood. The metadata from the Heathcare Facilities shapefile is also included here. The Licensed Healthcare Facilities point layer represents the locations of all healthcare facilities licensed by the State of California, Department of Health Services (DHS), as of the publication date. Facility address information is maintained and provided by the Office of Statewide Health Planning and Development (OSHPD). Facility types include hospitals, nursing homes, clinics, etc.
This dataset provides an estimate of the lengths of levees and seawalls that would need to built or fortified to protect development along the California coast from a 100-year coastal flood event with a 1.4 meter sea-level rise.
The Base Flood Elevation, representing the elevation of the 100-year coastal flood, is derived for the entire California coastline. Elevation data is in NAVD88, rounded to the nearest half foot. Euclidean Allocation was used to extrapolate the elevations from the BFE line 10 kilometers inland from the coast. The extent of this dataset covers fthe California coast from the Oregon border south to Monterey Bay.
This dataset shows the footprints of wastewater treatment plants (WWTP's) in the San Francisco Bay that are potentially vulnerable to a 100-year coastal flood with a 1.4 meter sea level rise.
The Erosion hazard zone dataset for the year 2100 represents the areas vulnerable to erosion with a sea-level rise of 1.4 meters. This dataset is a merge of the Dune and Bluff hazard datasets created by Philip Williams and Associates
This dataset shows schools that are vulnerable to a 100-year coastal flood event under current conditions in California. The school data was extracted from the FEMA HAZUS model and was intersected with the flooding layers created by the Pacific Institute and USGS/SCRIPPS.
The polygon represents the 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).
The Base Flood Elevation, representing the elevation of the 100-year coastal flood, is derived for the entire California coastline. Elevation data is in NAVD88, rounded to the nearest half foot. Euclidean Allocation was used to extrapolate the elevations from the BFE line 10 kilometers inland from the coast. This dataset covers the California coastline from Monterey Bay south to the Mexico border.
This is a small subset of 12 long-term tide stations on the California Coast. The elevations of Mean Lower Low Water (MLLW), Mean Low Water (MLW), Mean Sea Level (MSL), Mean High Water (MHW), and Mean Higher High Water (MHHW) are given fore each station. Each station has at least 30 years of records, sufficient for some trend analysis and for performing a frequency analysis on the tide elevations.
The bluff hazard zone dataset for the year 2100 represents the areas on the northern and central California coast (from Santa Barbara to the Oregon border) vulnerable to erosion with a sea-level rise of 1.4 meters.

The bay area levees map depicts the locations of levees around the San Francisco Bay Area. It was created using a combination of the Digital Flood Insurance Rate Maps (DFIRM) data from FEMA and digitized lines from USGS 7.5 minute Topo maps and Google Earth aerial imagery. The data source for each feature is described in the Source attribute field as derived from either FEMA or from the Pacific Institute.
This dataset shows police stations that are vulnerable to a 100-year coastal flood event under current conditions in California. The police station data was extracted from the FEMA HAZUS model and was intersected with the flooding layers created by the Pacific Institute and USGS/SCRIPPS.
This data layer is a compilation of all of the coastal flood elevation data available from the published Flood Insurance Studies for the California coast.
