Description: Original data downloaded from http://www.fws.gov/wetlands/Data/DataDownload.html#Stateon March 22, 2011. See "ESRI Fields and Subtypes" and "Data Quality" in this metadata document for more detail on how the dataset was constructed. Information from original NWI metadata:"This data set represents the extent, approximate location and type of wetlands and deepwater habitats in the conterminous United States. These data delineate the areal extent of wetlands and surface waters as defined by Cowardin et al. (1979). Certain wetland habitats are excluded from the National mapping program because of the limitations of aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and near shore coastal waters. Some deepwater reef communities (coral or tuberficid worm reefs) have also been excluded from the inventory. These habitats, because of their depth, go undetected by aerial imagery. By policy, the Service also excludes certain types of "farmed wetlands" as may be defined by the Food Security Act or that do not coincide with the Cowardin et al. definition. Contact the Service's Regional Wetland Coordinator for additional information on what types of farmed wetlands are included on wetland maps.The wetland maps were produced as topical overlays using U.S. Geological Survey topographic maps as the base. The hard copy product is a composite map showing topographic and planimetric features from the USGS map base and wetlands and deepwater habitats from the Service's topical overlay. Thus, the data are intended for use in publications, at a scale of 1:24,000 or smaller. Due to the scale, the primary intended use is for regional and watershed data display and analysis, rather than specific project data analysis. The map products were neither designed or intended to represent legal or regulatory products.Questions or comments regarding the interpretation or classification of wetlands or deepwater habitats can be addressed by visiting http://www.fws.gov/wetlands/FAQs.htmlThese data were developed in conjunction with the publication Cowardin, L.M., V. Carter, F.C. Golet, and E.T. LaRoe. 1979. Classification of Wetlands and Deepwater Habitats of the United States. U.S. Department of the Interior, Fish and Wildlife Service, Washington, DC. FWS/OBS-79/31. Alpha-numeric map codes have been developed to correspond to the wetland and deepwater classifications described.These spatial data are not designed to stand alone. They form topical overlays to the U.S. Geological Survey 1:24,000 or 1:25,000 scale topographic quadrangles. Note that coastline delineations were drawn to follow the extent of wetland or deepwater features as described by this project and may not match the coastline shown in other base maps.Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government.Although this Federal Geographic Data Committee-compliant metadata file is intended to document the data set in nonproprietary form, as well as in Arc/INFO format, this metadata file may include some Arc/INFO-specific terminology."

Description: Phase 1 Data: Created by buffering NHD rivers to 500m and removing any non-natural land cover FMMP or more detailed veg data if available. The Active River Area (ARA) conservation framework provides a conceptual and spatially explicit basis for the assessment, protection, management, and restoration of freshwater and riparian ecosystems. The ARA framework is based upon dominant processes and disturbance regimes to identify areas within which important physical and ecological processes of the river or stream occur. The framework identifies five key subcomponents of the active river area: 1) material contribution zones, 2) meander belts, 3) riparian wetlands, 4) floodplains, and 5) terraces. These areas are defined by the major physical and ecological processes associated and explained in the context of the continuum from the upper, mid and lower watershed in the ARA framework paper (Smith et al. 2008). The framework provides a spatially explicit manner for accommodating the natural ranges of variability to system hydrology, sediment transport, processing and transport of organic materials, and key biotic interactions. - See more at: https://www.conservationgateway.org/ConservationByGeography/NorthAmerica/UnitedStates/edc/reportsdata/freshwater/floodplains/Pages/default.aspx#sthash.Oc74BvF5.dpuf
Description: Hydrogeologically Vulnerable Areas Map:
Background: In response to Executive Order D-5-99, State Water Board staff created a map wherepublished hydrogeologic information indicates soil or rock conditions that may be morevulnerable (or susceptible) to groundwater contamination: ”HydrogeologicallyVulnerable Areas.” The map was created due to groundwater concerns over releases ofMTBE, primarily from leaking underground storage tank sites. However, areas that arevulnerable to MTBE may also be vulnerable to other contaminants released at thesurface.The map was created in 2000 using Department of Water Resources (DWR) and USGeological Survey publications. Data from these publications were used to identifyareas where geologic conditions are more likely to allow recharge at rates substantiallyhigher than in lower permeability or confined areas of the same groundwater basin.The identified areas are associated by a metadata table (in the following pages) whichidentifies (1) DWR basin name and number, (2) published source of information (i.e.,title, date, author, and appropriate page, figure, table, or plate number), and (3) specificcriteria upon which the vulnerability category is based.Groundwater resources underlying designated (i.e., published) recharge, rapidinfiltration, or unconfined areas were considered categorically more vulnerable topotential contaminant releases than groundwater underlying areas of slower recharge,lower infiltration rates, or intervening low permeability deposits (i.e., confining layers).

The CASGEM Groundwater Basin Prioritization (Basin Prioritization) is a statewide ranking of groundwater basin importance that incorporates groundwater reliance and focuses on basins producing greater than 90% of California’s annual groundwater.
