Historical dataset of population level and growth rate for the Seattle metro area from 1950 to 2025.

These layers are used as part of the City of Seattle Zoned Development Capacity Model 2016. Includes all input and output layers..To estimate potential development, the City of Seattle maintains a zoned development capacity model that compares existing development to an estimate of what could be built under current zoning. The difference between existing and potential development yields the capacity for new residential and commercial development.There is a report of summary findings available as part of Seattle 2035 as well as resources for reports, methodologies and data.When downloading the data, please select a layer and then "GDB Download" under "Additional Resources" to preserve long field names. The associated file geodatabase contains all the feature classes for the 10 layers represented.

Displays Environmentally Critical Areas (ECA) in the City of Seattle. For more information about the definition of the ECA layers, see Seattle Municipal Code section 25.09.

Displays historic landfill locations.A polygon feature class showing landfill areas and former landfill sites. Used to implement and regulate the City of Seattle's Environmentally Critical Areas (ECA) policies. This layer was table digitized in 1996 using abandoned landfill information from King County Department of Public Health. For those abandoned landfills emitting methane, a 1,000 foot buffer was created and so indicated in the attribute table.For more information about the definition of landfill areas, see Seattle Municipal Code section 25.09.012, Environmentally Critical Areas (ECA) definitions.

This data represents police response activity. Each row is a record of a Call for Service (CfS) logged with the Seattle Police Department (SPD) Communications Center. Calls originated from the community and range from in progress or active emergencies to requests for problem solving. Additionally, officers will log calls from their observations of the field.

Previous versions of this data set have withheld approximately 40% of calls. This updated process will release more than 95% of all calls but we will no longer provide latitude and longitude specific location data. In an effort to safeguard the privacy of our community, calls will only be located to the “beat” level. Beats are the most granular unit of management used for patrol deployment. To learn more about patrol deployment, please visit: https://www.seattle.gov/police/about-us/about-policing/precinct-and-patrol-boundaries.

As with any data, certain conditions and qualifications apply:

1) These data are queried from the Data Analytics Platform (DAP), and updated incrementally on a daily basis. A full refresh will occur twice a year and is intended to reconcile minor changes.

2) This data set only contains records of police response. If a call is queued in the system but cleared before an officer can respond, it will not be included.

3) These data contain administrative call types. Use the “Initial” and “Final” call type to identify the calls you wish to include in your analysis.

We invite you to engage these data, ask questions and explore.

Seattle Home Price Index - Historical chart and current data through 2025.

CO-OPS has been involved with tsunami warning and mitigation since the Coast and Geodetic Survey started the Tsunami Warning System in 1948 to provide warnings to the Hawaiian Islands. After the December 2004 Indian Ocean tsunami, CO-OPS was tasked to coordinate with the NOAA Tsunami Warning Centers in upgrading existing stations with new Data Collection Platform (DCP) and communications technology and with expanding the tsunami warning capabilities of the National Water Level Observation Network (NWLON). Work began in 2005 to upgrade 33 existing water level stations and install 16 new stations from the Pacific Ocean to the Caribbean Sea by October 2006. As of September 2006, all 33 upgrades are complete, as well as 15 of the 16 new installations. As of October 2006, the NWLON consist of 196 long-term water level stations along all U.S. coasts, including the Great Lakes, Alaska, Hawaii, the Pacific Ocean Island Territories, Puerto Rico, and the U.S. Virgin Islands. The NOAA National Centers for Environmental Information (formerly National Geophysical Data Center) serves as the archive center for these data and provides the historical data to users.

Cedar River Watershed Cultural Landscape District boundary. Recognized by the Washington State Department of Archaeology and Historic Preservation (DAHP) this is the boundary of an 'Historic Site', described as 'a landscape significant for its association with a historic event, activity or person'. DAHP states: 'Cultural Landscapes provide a sense of place and identity; they map our relationship with the land over time; and they are part of our national heritage and each of our lives. They are sites associated with a significant event, activity, person or group of people and can range in size from thousands of acres of rural land to historic homesteads.' The Cultural Landscape District Boundary in the Cedar River Municipal Watershed was created in the early 2000's. It was informed in part by the location of known historic sites at the time.

This data included a variety of home attributes, geo-locational and property change data that I've collected this data over the past decade. The use of historical data together with current data in the cleaning and preparation allows for more precise identification of changes such as remodels, tear-down and new construction. For a more complete view of what the preparation process does see: https://github.com/andykrause/kingCoData.

These data are developed for the purpose of developing predictive home price models and housing price indexes.
