GIS Data for Pierce County

The Pierce County WA Open GeoSpatial Data Portal (v2.1) offers free public access to a comprehensive collection of GIS data sets and mapping resources maintained by Pierce County. Visitors can expect to find detailed “Data” covering geographic, land use, environmental, and infrastructure themes available for download or direct use, all provided on an “AS IS” basis without warranty of accuracy or fitness for a particular purpose. The portal enables users to explore spatial data using interactive mapping tools hosted by Esri, but users must independently verify data quality and accept terms that prohibit representing the data as official County business or agency work. While the site facilitates easy access to updated geospatial information, it explicitly disclaims liability for data errors or service interruptions and restricts unauthorized reproduction or branding of Pierce County materials. In sum, this trusted portal is ideal for professionals, researchers, and the public seeking up-to-date, government-sourced GIS data to support planning, analysis, and decision-making in Pierce County, Washington.
