This is a layer of water service boundaries for 45,973 community water systems that deliver tap water to 307.7 million people in the US. This amounts to 97% of the population reportedly served by active community water systems and 93% of active community water systems. The layer is based on multiple data sources and a methodology developed by SimpleLab and collaborators called a Tiered, Explicit, Match, and Model approach–or TEMM, for short. The name of the approach reflects exactly how the nationwide data layer was developed. The TEMM is composed of three hierarchical tiers, arranged by data and model fidelity. First, we use explicit water service boundaries provided by states. These are spatial polygon data, typically provided at the state-level. We call systems with explicit boundaries Tier 1. In the absence of explicit water service boundary data, we use a matching algorithm to match water systems to the boundary of a town or city (Census Place TIGER polygons). When multiple water systems match to the same TIGER boundary, we employ a "best match" algorithm that assigns one water system to one TIGER place based on features like population served and other locational information about the water system. Finally, in the absence of an explicit water service boundary (Tier 1) or a TIGER place polygon match (Tier 2), a statistical model trained on explicit water service boundary data (Tier 1) is used to estimate a reasonable radius at provided water system centroids, and model a spherical water system boundary (Tier 3). Water system centroids are taken from the ECHO database; however, where a system centroid is labeled as a county or state centroid, we take several steps to assign a better centroid (using sources like UCMR or TIGER). A summary of the systems and population assigned to different tiers is as follows:

Population coverage rates per Tier, for systems with population reported: - Tier 1: 49.3% population covered (155,869,771 people) - Tier 2: 35.13% population covered (111,074,087 people) - Tier 3: 12.9% population covered (40,771,645 people)

Active community water systems coverage rates per Tier: - Tier 1: 35.7% system covered (17645 systems) - Tier 2: 22.42% system covered (11079 systems) - Tier 3: 34.9% system covered (17249 systems) - No Tier/Geometry: 6.98% system covered (3451 systems)

Several limitations to this data exist–and the layer should be used with these in mind. The case of assigning a Census Place TIGER polygon to the "best match" water system first introduced in v2.0.0 requires further validation. Tier 3 boundaries have modeled radii stemming from a lat/long centroid of a water system facility; but the underlying lat/long centroids for water system facilities are of variable quality. It is critical to evaluate the "geometry quality" column (included from the EPA ECHO data source) when looking at Tier 3 boundaries; fidelity is very low when geometry quality is a county or state centroid– but we did not exclude the data from the layer. Since v 2.0.0 we have improved the percentage of Tier 3 geometries with state centroids and county centroids from 50% of Tier 3 boundaries to 30% of Tier 3 boundaries. Missing water systems are typically those without a centroid, in a U.S. territory, or missing population and connection data. Finally, Tier 1 systems are assumed to be high fidelity, but rely on the accuracy of state data collection and maintenance.

Changelog:

3.0.0 (2022-10-31)

• Adding manually-contributed systems from the Internet of Water's Github: https://github.com/cgs-earth/ref_pws/raw/main/02_output/contributed_pws.gpkg
• Refactored to use geopackage through most of pipeline instead of geojson
• Added geometry_source_detail column to, where possible, include notes provided by the data sources themselves about how the geometry was sourced

Map of Chicago community areas.

The Communities Boundary File (CMN) represents community boundaries within Canada.

Presently Neighbourhood Boundaries are only available in urban areas and Community Boundaries are available in both urban and rural areas.

Definition of Community: a geographically defined area identified in part by a group of interacting people living in a common location. In addition to a common location, the community may be re-enforced by similarities shared within a location that include shared cultural, ethnic, or moral characteristics.

Note: In 2012, there was a datum change from NAD83 to WGS84.

This EnviroAtlas dataset shows the boundaries of all EnviroAtlas Communities. It represents the outside edge of all the block groups included in each EnviroAtlas community. This dataset was produced by the US EPA to support research and online mapping activities related to EnviroAtlas. EnviroAtlas (https://www.epa.gov/enviroatlas) allows the user to interact with a web-based, easy-to-use, mapping application to view and analyze multiple ecosystem services for the contiguous United States. The dataset is available as downloadable data (https://edg.epa.gov/data/Public/ORD/EnviroAtlas) or as an EnviroAtlas map service. Additional descriptive information about each attribute in this dataset can be found in its associated EnviroAtlas Fact Sheet (https://www.epa.gov/enviroatlas/enviroatlas-fact-sheets).

The data contains Multipolygon information for the Boroughs of Chicago used for geospatial analysis. The Coordinate Reference System is EPSG:4326 (WGS84). The file is compressed with xz.

The Neighbourhood Boundary File (NBH) represents neighbourhood boundaries within Canadian communities. Neighbourhoods are a geographically localized area within a larger city, town or suburb. Neighbourhoods are often social communities with considerable face-to-face interaction among members. Neighbourhoods can be used to refer to the small group of houses with similar housing types and market values. Neighbourhoods can also describe an area surrounding a local institution patronized by residents, such as a church, school, or social agency. The concept of neighborhood includes both geographic (place-oriented) and social (people-oriented) components.

This layer shows all incorporated and unincorporated areas of Los Angeles County. The incorporated city boundaries are maintained by the Department of Public Works as part of the cadastral landbase, and reflects the most current annexations as of the date listed below. The unincorporated areas are maintained by the Department of Regional Planning (aka LA County Planning) for land use planning efforts. This is especially important as it relates to the County's General Plan and various area, community, and neighborhood plan updates. Please see relevant links below for more related information:Department of Regional Planning (LA County Planning) - About page.Link to official Public Works City boundary layer (shows all cities and unincorporated area, but not the individual unincorporated communities as recognized by LA County Planning).Link to official Public Works City Annexations layer and web application.Link to Countywide Statistical Areas layer (jurisdictions broken down by neighborhood boundaries for the purpose of reporting statistics)LAST UPDATED: 9/1/25 for an annexation to the City of San Gabriel, from the unincorporated community of East Pasadena - East San Gabriel (APN 5374027005).

Boundaries of Registered Community Organizations (RCO) as established under the City of Philadelphia Zoning Code enacted December 15, 2011 and made effective August 22, 2012.

This shapefile includes neighborhoods boundaries from Community Foundation, Innovate Memphis, neighborhood CDCs, and other civic groups for use on the map tools "Public Safety" and "Open311." It is not an exhaustive list. If you'd like add your group's boundaries, please contact Sarah Harris at sarah.harris@memphistn.gov.

On January 13, 2014, the Ministry of Children and Youth Services created a new regional boundary structure. It combined the previous 9 Service Delivery Division regions and 4 Youth Justice Services Division regions. The result is 5 new Ministry of Children and Youth Services regions. These new regional boundaries are integrated with the Ministry of Community and Social Services' 5 regional boundaries.
