This layer represents the geographic areas 4 below. Category 1-3, census tracts, are in the other layer.In this designation, CalEPA formally designated four categories of geographic areas as disadvantaged:Census tracts receiving the highest 25 percent of overall scores in CalEnviroScreen 4.0 (1,984 tracts).Census tracts lacking overall scores in CalEnviroScreen 4.0 due to data gaps, but receiving the highest 5 percent of CalEnviroScreen 4.0 cumulative pollution burden scores (19 tracts).Census tracts identified in the 2017 DAC designation as disadvantaged, regardless of their scores in CalEnviroScreen 4.0 (305 tracts).Lands under the control of federally recognized Tribes. For purposes of this designation, a Tribe may establish that a particular area of land is under its control even if not represented as such on CalEPA’s DAC map and therefore should be considered a DAC by requesting a consultation with the CalEPA Deputy Secretary for Environmental Justice, Tribal Affairs and Border Relations at TribalAffairs@calepa.ca.gov. This file contains legal AIANNH entities for which the Census Bureau publishes data. The legal entities consist of federally recognized American Indian Reservations (AIRs) and Off-Reservation Trust Lands (ORTL).

Administrative Boundaries

This dataset contains the boundaries for the Native American Reservations in the six counties in the Southern California Association of Governments (SCAG) region, as defined by the United States Census Bureau.

This polygon feature class contains exterior reservation boundaries of Native American Indian Reservations and Rancherias in U.S. EPA Region 9. The primary data is administered by the Bureau of Indian Affairs (BIA) Pacific Region Office and the AZ/NV BLM Surface Management office. Within the U.S. Department of the Interior (DOI), BIA provides the list of federally recognized tribes and only provides legal boundary information when the tribes need supporting records, if a boundary is based on treaty or another document that is historical or open to legal interpretation, or when another tribal, state, or local government challenges the depiction of a reservation or off-reservation trust land.

The BIA/BLM data has been appended by the addition of office locations for tribal consortia and landless tribes. Attributes derive from the Indian Nations Database maintained by the EPA Region 9 Tribal, Intergovernmental and Policy Division.

This map shows the 2022 disadvantaged communities designated by CalEPA for the purpose of SB 535. These areas represent:Highest scoring 25% of census tracts from CalEnviroScreen 4.0, along with census tracts scoring in the top 5% of the Pollution Burden indicator but without an overall CalEnviroScreen score due to due to unavailable or unreliable Population Characteristics indicator data and score.All census tracts currently identified as disadvantaged but not in the highest scoring 25% census tracts in version 4.0 (i.e., the highest scoring 25% of census tracts in CalEnviroScreen 3.0 along with the census tracts with the highest 5% Pollution Burden scores, but without an overall CalEnviroScreen score).

ObjectivesTo describe the food environments experienced by American Indians living on tribal lands in California.MethodsGeocoded statewide food business data were used to define and categorize existing food vendors into healthy, unhealthy, and intermediate composite categories. Distance to and density of each of the composite food vendor categories for tribal lands and nontribal lands were compared using multivariate linear regression. Quantitative results were concurrently triangulated with qualitative data from in-depth interviews with tribal members (n = 24).ResultsAfter adjusting for census tract-level urbanicity and per capita income, results indicate there were significantly fewer healthy food outlets per square mile for tribal areas compared to non-tribal areas. Density of unhealthy outlets was not significantly different for tribal versus non-tribal areas. Tribal members perceived their food environment negatively and reported barriers to the acquisition of healthy food.ConclusionsUrbanicity and per capita income do not completely account for disparities in food environments among American Indians tribal lands compared to nontribal lands. This disparity in access to healthy food may present a barrier to acting on the intention to consume healthy food.

This map shows the 2022 disadvantaged communities designated by CalEPA for the purpose of SB 535. These areas represent:

• Highest scoring 25% of census tracts from CalEnviroScreen 4.0, along with census tracts scoring in the top 5% of the Pollution Burden indicator but without an overall CalEnviroScreen score due to due to unavailable or unreliable Population Characteristics indicator data and score.
• All census tracts currently identified as disadvantaged but not in the highest scoring 25% census tracts in version 4.0 (i.e., the highest scoring 25% of census tracts in CalEnviroScreen 3.0 along with the census tracts with the highest 5% Pollution Burden scores, but without an overall CalEnviroScreen score). See the Disadvantaged Communities 2017 map here.

This polygon shapefile represents tribal areas in Inyo County, Califorina. This layer is a part of a collection of data obtained from Inyo County Information Services Department.

This project examines the intergovernmental relationship between San Diego County Tribal Nations and the San Diego Association of Governments (SANDAG) and its development of relationship and practices to prioritize Tribal transportation and mobility needs within the larger regional planning process. SANDAG and Southern California Tribal Chairmen’s Association (SCTCA) established a formal relationship with Tribal leadership and representation on several key regional committees that provide a platform for Tribal issues to be included in the regional planning process. While this relationship is groundbreaking, this research assesses the collaboration and examines the practices that are most effective to potentially replicate these Native-Local practices in other regions in the Southwest. SANDAG and SCTCA have a viable working relationship, however, we want to know how this relationship can be improved and expanded to support long-term sustainability and resiliency for Tribes in San Diego County. The research is grounded in a place-based, oral history format that supports Indigenous traditional knowledge formation and current practices within the discipline of American Indian Studies to blend cultural studies methodologies with transportation policy analysis of the overall regional history of transportation development to examine relevant social, political, and cultural issues impacting the lives of First Peoples. Data collection included: 1) Tribal interviews and transcriptions to develop the oral history, 2) Critical review of the history of Southern California Tribal transportation and mobility, and 3) Development of a GIS Story Map of the territory described with transportation corridors, Tribal roads, and other relevant data provided in the oral histories.

Critical habitat in freshwater riverine areas includes the stream channels and a lateral extent as defined by the ordinary high-water line (33 CFR 329.11). In areas for which the ordinary high-water line has not been defined pursuant to 33 CFR 329.11, the lateral extent is defined by the bankfull elevation. Bankfull elevation is the level at which water begins to leave the channel and move into the floodplain and is reached at a discharge which generally has a recurrence interval of 1 to 2 years on the annual flood series. Critical habitat in bays and estuaries includes tidally influenced areas as defined by the elevation of mean higher high water (MHHW).No areas were deemed ineligible for designation. No unoccupied areas were designated. 14 areas based on economic impacts and 5 areas based on national security impacts were excluded from this critical habitat designation and clipped out of the data. The following tribal lands were excluded from this designation, but were not clipped out of the data:(1) Cachil DeHe Band of Wintun Indians of the Colusa Indian Community, California(2) Cher-Ae Heights Trinidad Rancheria, California(3) Confederated Tribes of the Coos, Lower Umpqua, and Siuslaw, Oregon(4) Coquille Indian Tribe, Oregon(5) Hoh Tribe, Washington(6) Jamestown S'Klallam Tribe, Washington(7) Lower Elwha Tribe, Washington(8) Makah Tribe, Washington(9) Quileute Tribe, Washington(10) Quinault Tribe, Washington(11) Shoalwater Bay Tribe, Washington(12) Wiyot Tribe, California(13) Yurok Tribe, California

Critical habitat in bays and estuaries includes tidally influenced areas as defined by the elevation of mean higher high water (MHHW). The boundary between coastal marine areas and bays and estuaries is delineated by the COLREGS lines (33 CFR 80). Critical habitat in coastal marine areas is defined by the zone between the 60 fathom (fm) depth bathymetry line and the line on shore reached by mean lower low water (MLLW), or to the COLREGS lines.No areas were deemed ineligible for designation. No unoccupied areas were designated. 14 areas based on economic impacts and 5 areas based on national security impacts were excluded from this critical habitat designation and clipped out of the data. The following tribal lands were excluded from this designation, but were not clipped out of the data:(1) Cachil DeHe Band of Wintun Indians of the Colusa Indian Community, California(2) Cher-Ae Heights Trinidad Rancheria, California(3) Confederated Tribes of the Coos, Lower Umpqua, and Siuslaw, Oregon(4) Coquille Indian Tribe, Oregon(5) Hoh Tribe, Washington(6) Jamestown S'Klallam Tribe, Washington(7) Lower Elwha Tribe, Washington(8) Makah Tribe, Washington(9) Quileute Tribe, Washington(10) Quinault Tribe, Washington(11) Shoalwater Bay Tribe, Washington(12) Wiyot Tribe, California(13) Yurok Tribe, California

Shapefile contains census tracts and polygons of Tribal Lands identified as Disadvantaged Communities per SB 535 for the five counties that are included in the Bay Area Regional Climate Action Planning Initiative Frontline Communities Map.

The original shapefile was downloaded from the Office of Environmental Health Hazard Assessment (OEHHA), SB 535 Disadvantaged Communities webpage. The “Clip” tool in ArcMap was used to select only those features which are located within the boundaries of the five Bay Area counties included in the Frontline Communities Map. No display filters were used to visualize the features in the final map. To learn more about the methodology behind the original dataset, please visit: https://oehha.ca.gov/calenviroscreen/sb535

The Frontline Communities Map is meant to help identify communities that are considered frontline communities for the purpose of the USEPA’s Climate Pollution Reduction Grant (CPRG) program’s planning effort, which is a five-county climate action planning process led by the Air District. USEPA refers to these communities as low-income and disadvantaged communities (LIDACs).

Senate Bill (SB) 535 (De León) mandates that California use certain Cap-and-Trade auction proceeds to fund investments in “disadvantaged communities” (DACs). It charges the California Environmental Protection Agency (CalEPA) with the responsibility to designate DACs.

In issuing previous designations, CalEPA relied upon the California Communities Environmental Health Screening Tool (CalEnviroScreen), a mapping tool developed by the Office of Environmental Health Hazard Assessment (OEHHA). On October 13, 2021, OEHHA released a new final version of CalEnviroScreen, Version 4.0. CalEPA determined that the improvements and updates in Version 4.0 were sufficiently material to warrant new designations of disadvantaged communities, pursuant to SB 535 (DAC designations).

After receiving public input at workshops and in written comments, in May 2022, CalEPA released its updated designation of disadvantaged communities for the purpose of SB 535. In this designation, CalEPA formally designated four categories of geographic areas as disadvantaged: 1. Census tracts receiving the highest 25 percent of overall scores in CalEnviroScreen 4.0 (1,984 tracts). 2. Census tracts lacking overall scores in CalEnviroScreen 4.0 due to data gaps, but receiving the highest 5 percent of CalEnviroScreen 4.0 cumulative pollution burden scores (19 tracts). 3. Census tracts identified in the 2017 DAC designation as disadvantaged, regardless of their scores in CalEnviroScreen 4.0 (307 tracts). 4. Lands under the control of federally recognized Tribes.
