California State Senate district boundaries intended for the NEVI map.Data downloaded in October 2024 from https://gis.data.ca.gov/maps/b31d93f08c074753b89f8cbb0b8beed9/about.

The legislative districts contain the geographically defined territories used for representation in the California State Assembly, California State Senate and the U.S. House of Representatives from California. These three boundary layers were approved by the California Citizens Redistricting Commission in 2021 following the completion of the 2020 United States Census.

Final approved map by the 2020 California Citizens Redistricting Commission for the California State Senate.

Final approved map by the 2020 California Citizens Redistricting Commission for the California State Senate; the authoritative and official delineations of the California State Senate drawn during the 2020 redistricting cycle. The Citizens Redistricting Commission for the State of California has created statewide district maps for the State Assembly, State Senate, State Board of Equalization, and United States Congress in accordance, with the provisions of Article XXI of the California Constitution. The Commission has approved the final maps and certified them to the Secretary of State.

Line drawing criteria included population equality as required by the U.S. Constitution, the Federal Voting Rights Act, geographic contiguity, geographic integrity, geographic compactness, and nesting. Geography was defined by U.S. Census Block geometry.

Each of the 40 Senate districts has an ideal population of nearly one million people and represents the largest state legislative districts in the nation. In consideration of population equality, the Commission chose to limit the population deviation as close to zero percent as practicable. Per the California Constitution, the Commission strived to nest two Assembly districts where practicable. However, higher ranking criteria made this difficult in practice. While the size of the Senate districts allowed the Commission to recognize broadly shared interests, these interests did not always overlap exactly with the interests of smaller communities recognized in the related Assembly districts. Based on the large number of people in each district, there were a variety of different interests that were balanced and included.

This is the last boundary change until the next redistricting following the 2030 Census. All of the districts now reflect the 2021 Citizens Redistricting Commission(CRC) plan. The only thing that will change is the members' names and parties as elections are held, appointments are made, or party affiliations change.Senate Districts feature layer is updated as-needed and we expect to update it more regularly in the future.Schema:F2020_POP: The 2020 population of the district as reported by the census.F2020_HU: Number of housing units in the district in 2020 as reported by the census.CRC_POP: Citizen's Redistricting Commission population.District: The District is the district number.Party: The Party is the party represented.last_name: The last name is the last name of the representative.first_name: The first name is the first name of the representative.district_website: The district website is the link to the district website.For more information about the F2020_Pop and the F2020_HU visit: https://www.census.gov/programs-surveys/decennial-census/about/rdo/summary-files.html

This web map of California legislative districts includes the geographically defined territories used for representation in the California State Assembly, California State Senate and the US House of Representatives from California. These three boundary layers are derived from the US Census Bureau's 2018 TIGER/Line database and are designed to overlay with the California Department of Education’s (CDE) education related GIS content.

The 80 California State Assembly Districts represent the geographically defined territories used for electing members to the lower (house) chamber of the California State Legislature. The current state assembly boundaries were determined by the California Citizens Redistricting Commission following the completion of the 2010 United States Census and will remain valid until 2020.

The 40 state senate districts represent the geographically defined territories used for electing members to the upper (senate) chamber of the California State Legislature. The current state senate boundaries were determined by the California Citizens Redistricting Commission following the completion of the 2010 United States Census and will remain valid until 2020.

The 53 congressional districts within the State of California represent the geographically defined territories used for electing members to the U.S. House of Representatives. The current U.S. Congressional boundaries in California were determined by the California Citizens Redistricting Commission following the completion of the 2010 United States Census and will remain valid until 2020

The 2023 cartographic boundary KMLs are simplified representations of selected geographic areas from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). These boundary files are specifically designed for small-scale thematic mapping. When possible, generalization is performed with the intent to maintain the hierarchical relationships among geographies and to maintain the alignment of geographies within a file set for a given year. Geographic areas may not align with the same areas from another year. Some geographies are available as nation-based files while others are available only as state-based files. State Legislative Districts (SLDs) are the areas from which members are elected to state legislatures. The SLDs embody the upper (senate) and lower (house) chambers of the state legislature. Nebraska has a unicameral legislature and the District of Columbia has a single council, both of which the Census Bureau treats as upper-chamber legislative areas for the purpose of data presentation; there are no data by SLDL for either Nebraska or the District of Columbia. A unique three-character census code, identified by state participants, is assigned to each SLD within a state. In Connecticut, Illinois, Louisiana, New Hampshire, Wisconsin, and Puerto Rico, the Redistricting Data Program (RDP) participant did not define the SLDs to cover all of the state or state equivalent area. In these areas with no SLDs defined, the code "ZZZ" has been assigned, which is treated as a single SLD for purposes of data presentation. The generarlized boundaries in this file are based on the most recent state legislative district boundaries collected by the Census Bureau for the 2022 election year and provided by state-level participants through the RDP.

The California Citizens Redistricting Commission (Commissioner) was established pursuant to the procedures set forth by Proposition 11, the Voters First Act, and Proposition 20, the Voters First Act for Congress, the provisions of which are now found in Section 2 of Article XXI of the California Constitution and at Government Code Section 8252. These constitutional and statutory provisions set forth the Commission’s responsibilities with respect to drawing the boundary lines for the California Assembly, Senate, Board of Equalization and Congressional districts (the Maps).Resolution of August 15, 2011 certifying the statewide California Congressional districts were approved by the Commission in the manner required by Section 2 of Article XXI of the California Constitution; a copy of the statewide Congressional map; copies of the 53 individual Congressional districts; and a “disc” labeled crc_20110815_congress_certified_statewide.zip SHA-1: 1893c0695a42454a202f5b1ef433abff6b491db9 containing the unique data files for the Congressional districts from which the statewide and individual district maps are created.Commission Background:In accordance with the Voters FIRST Act (Act), the California State Auditor randomly selected the first eight members of the first Citizens Redistricting Commission (Commission) on November 18, 2010. These first eight commissioners—three who are Democrats, three who are Republican, and two who are either Decline-to-State or are registered with another party—were part of the 36 eligible applicants that remained in the sub-pools after the legislative leaders, exercised their authority to make strikes and eliminated the names of 24 applicants from the pool of 60 of the most qualified applicants identified on September 23, 2010 by the Auditor’s Applicant Review Panel (Panel). The Panel reviewed and evaluated the applicants based on criteria set forth by the Act approved by voters in November 2008; including relevant analytical skills, the ability to be impartial; and a demonstrated appreciation for California’s diverse demographics and geography.

The State Senate Districts layer contains polygons for California State Senate Districts. The source for the information in this layer is the Los Angeles Registrar/Recorder's Precinct Information File (PIF), which is designed to match the Thomas Brothers TRNL (road network) layer. Where boundaries are defined by streets, water, city boundaries, or other features, those arc segments are copied to the districts layer, so that the boundaries and other layer features match perfectly.

The California Department of Transportation (Caltrans) and the California Energy Commission (CEC) are partnering to implement the federal National Electric Vehicle Infrastructure (NEVI) Program, which allocates $5 billion to the states to create a nationwide, interconnected network of DC fast chargers along the National Highway Systems. California's share will be $384 million over 5 years. This map was developed to help prospective applicants and interested parties identify eligible areas for infrastructure deployment.InstructionsViewers can display corridor groups, corridor segments, electric vehicle (EV) charging stations, Justice40 disadvantaged communities, Tribal lands, California-designated low-income or disadvantaged communities, metropolitan planning organizations, regional transportation planning agencies, California state legislative districts, counties, Caltrans districts, utility districts, and congressional districts in this interactive map. The map initially displays corridor groups and their corridor segments included in the Round 2 NEVI solicitation. Viewers can toggle individual layers on and off using the map layers menu located to the right of the map. Some layers are organized into groups; viewers can toggle all layers within a group or select specific ones. The legend to the left of the map will show the layers that have been turned on. There is a search tool to the right of the map that enables viewers to type in an address and locate the address on the map. A basemap selector allows viewers to view road detail. Additional information on the map can be found under the information icon. Viewers can download the map files by clicking on the Data and Supplemental Links icon. Map layers include:A Corridor groups layer that shows designated corridor groups for California's NEVI funding program. Users can click on a corridor segment to view the start and end of each segment within a corridor group. When selected, a pop-up window will appear that identifies the corridor group number, corridor segment, corridor name, minimum number of charging stations required, minimum number of ports required, and needed locations, if applicable, for the corridor segment. Corridor group labels for enhanced accessibility. Note that labels are only visible at certain ranges (zoom in and out to view labels).

EV charging stations layers (existing DC fast charging stations that are located within one mile of a NEVI-eligible corridor offramp). One layer shows locations of EV charging stations with DC fast charging capabilities that meet the NEVI power level and four-port minimum requirement and could likely become part of the NEVI network if these stations became compliant with other NEVI program requirements such as data reporting. The other layer shows DC fast charging stations that do not meet NEVI power-level or port count requirements but could be upgraded to be NEVI-compliant. Users can click on EV charging stations and a pop-up window will appear with more information on the station (i.e., station address, total port count, minimum NEVI standard, etc.). These data were last updated in March 2024. Please refer to the Department of Energy's Alternative Fuels Data Center and PlugShare for up-to-date existing and planned DC fast charger site information. A layer showing Caltrans Districts.

BackgroundThe $5 billion NEVI Program is part of the $1.2 trillion Infrastructure Investment and Jobs Act (IIJA) signed into law by President Biden in November 2021. IIJA commits significant federal funding to clean transportation and energy programs throughout the U.S. to reduce climate changing greenhouse gas emissions. Caltrans is the designated lead agency for NEVI. The CEC is their designated state energy partner. Caltrans and the CEC have partnered to create California's Deployment Plan for the National Electric Vehicle Infrastructure Program that describes how the state plans to allocate its $384 million share of federal NEVI funds to build out a network of modern, high-powered DC fast chargers along federally designated Alternative Fuel Corridors throughout California. California's latest NEVI Deployment Plan was submitted to the Joint Office of Energy and Transportation on August 1, 2023 and approved on September 29, 2023. The Plans must be updated each year over 5 years.NEVI funds must be used initially on federally-designated Alternative Fuel Corridors (shown on the map).Each NEVI-funded DC fast charge station will have a minimum of four 150 kW Combined Charging System (CCS) connectors. Stations will be located no more than 50 miles apart along freeways and highways and no more than 1 mile from a freeway exit or highway roadway. States are required to emphasize equity, with at least 40 percent of NEVI benefits going to disadvantaged, low income, rural and Tribal communities.Data SourcesData are from the Federal Highway Administration's Alternative Fuel Corridors website, the U.S. Department of Energy's Alternative Fuels Data Center Station Data for Alternative Fuel Corridors (as of September 2022), Argonne National Laboratory's Electric Vehicle Charging Justice40 Map, and the California Air Resources Board's Map of California Climate Investments Priority Populations 2022 CES 4.0.
