This layer is a compilation of city jurisdictional information from three counties: King, Pierce and Snohomish, plus the unincorporated areas in each of the three counties. Uses the best available information from each of the 3 counties to produce the composite product for the jurisdictional areas and assumes the areas outside of the jurisdictions to be unincorporated. Updated whenever changes are made to any one of the source data sets. For King County this will be whenever CITY_AREA (parent is CITY_ANNEX) is updated to Spatial Data Warehouse. Pierce and Snohomish updates are shared with King County on quarterly to semi-annual basis. Updates are made so that the King County portion of this composite is synchronous with the information in the master King County jurisdiction layer.

This layer is a component of Administrative Areas.

These administrative layers represent incorporated areas, zip codes for King, Snohomish and Pierce counties and tribal lands.

Derived from King County comprehensive plan data. The rural towns allow urban land uses in the rural area. They are historic communities that were not incorporated, and subsequent to the Washington State GMA, and the adoption of the King County Urban Growth Boundary, are not eligable to be incorporated.

With the new 2017 DFIRM map panels are not issued to individual National Flood Insurance Program - NFIP communities but the one seamless countywide map is apportioned based on area covered without consideration of corporate boundaries. The exception is along the King County border were portions of the cities of Pacific and Auburn are not shown in Pierce County but will be mapped in the King County countywide DFIRM as the majority of those cities lay in King County. The map panel starts with a new countywide identifier of “53053C” plus the four digit panel locator and the latest edited suffix, currently “E”. Each NFIP community has a unique number that is necessary to be shown on Elevation Certificates and for writing a flood insurance policy (e.g. Unincorporated Pierce County is 530138) in the past this community number was on the map panel issued to that community. Care must be taken to ensure the property community is identified on the appropriate documents. This number can be found on FEMA website: (https://www.fema.gov/national-flood-insurance-program-community-status-bookThe) FEMA map panels are derived from the USGS 7.5 Minute Quad grid. A FEMA 1"=2000' map covers the exact area at a 7.5 Minute Quadrangle. FEMA publishes maps at three scales, 1"=2000', 1"=1000' and 1"=500'. The map scale can be determined by the panel number of the map. The map numbering on a 1"=2000' series map is divisible by 25 (e.g. 0150, 0650). The 1"=2000' maps are quartered (by aliquot parts) to become the 1"=1000' map, the map numbering are divisible by 5 (e.g. 0140, 630). The 1"=1000' are sub-divided again to create the 1"=500' scale maps used in more populated areas (e.g.0137, 0626).

An application (https://maps.seattle.gov/ACS-Neighborhood-Profiles) that presents U.S. Census Bureau 5-year American Community Survey data for census tracts in King County, Washington. Presented in a dashboard format with selectors for different time periods and levels of geographies, these snapshots are a curated set of data grouped into 12 topical profiles. Data is pulled from the demographic profiles DP02-DP05 and several supplemental tables for multiple nonoverlapping vintages starting in 2006-2010 and shown by the corresponding census tract vintage. Also includes the most recent release annually (usually released in December for the previous year) with the vintage identified in the "ACS Vintage" field. Use caution when looking at the most recent year as some data in the sample are the same as in the five-year period just prior.Data is presented in charts and graphs for pre-defined geographies as well as custom selection of census tracts either from a list or by selecting tracts on the map (shift-click to select multiple tracts). The census tract boundaries match the vintage of the ACS data (currently 2010 and 2020) so please note the geographic changes between the decades. Charts allow downloading of the summarized data shown in the chart.The City of Seattle geography does not include the small portions of tracts 263, 264, 265, so city totals will vary slightly from published Census Bureau numbers.Tracts have been coded as being within the City of Seattle as well as assigned to neighborhood groups called "Community Reporting Areas". These areas were created after the 2000 census to provide geographically consistent neighborhoods through time for reporting U.S. Census Bureau data. This is not an attempt to identify neighborhood boundaries as defined by neighborhoods themselves. Get all the data for these profiles from SeattleGeoData. The full range of data products from the U.S. Census Bureau can be found by visiting the online data portal Explore Census Data.Interested in mapping the ACS? Check out this gallery for mapping apps and other census related dashboards.Important notes: ACS estimates are based on a survey mailed to a small percentage of houeholds and may carry substantial margins of error for small geographic areas or population groups. The margin of error (MOE) is an indicator of the reliability of the ACS estimate. Please see the Census Bureau guidance on calculating ....can't find something easy to link to....The 2010 and 2015 ACS vintages use the 2010 census tracts. The years 2020 and beyond use the 2020 census tracts. There were a significant number of new tracts created in 2020 so please use caution when comparing at the tract level between those time periods.Medians for aggregated areas are the weighted averages of the medians for the tracts selected.Monetary values are inflation-adjusted to the vintage year.Housing characteristics may not match other sources of housing data such as the King County Assessor or City of Seattle permit reports.Credits:Most icons sourced from the Noun Project.(Lars Meiertoberens, MRK, Gan Khoon Lay ....)

Description

This polygon feature contains geographic and attribute information for the purpose of depicting Zoning Areas within the City of SeaTac, Washington. The data was compiled from existing zoning information and King County parcel data.To implement the SeaTac Comprehensive Plan's policies and objectives and the goals of the State Growth Management Act (GMA); To protect health, safety, and general welfare; To provide for the economic, social, and aesthetic advantages of orderly development and redevelopment through harmonious groupings of compatible and complementary land uses and the application of appropriate development standards; To provide for adequate public facilities and services in conjunction with development; To ensure public safety by restricting development of lands containing physical hazards and to minimize the adverse environmental impacts of development; and To ensure that land use decisions are made in accordance with the public interest and applicable laws of the State of Washington, including the Growth Management Act and subsequent amendments (Ord. 92-1041 --1)Updates to Zoning were made per Ordinance 18-1005, data was updated 3/28/2018.Updates to the Zoning were made per ORD17-1022, data was updated December 2017.Last amended in December 2015.The change to Angle Lake District Area Boundary was adopted on July 9th, 2015 (Ord. 15-1010).UL-5000 was changed to High Density Single Family Overlay Zone (HDS-OZ) on Nov 10, 2015.Segale properties were rezoned to UH-900 on Dec 8, 2015.Pursuant to Article XI, Section 11 of Washington State Constitution (Ord. 92-1041 -- 1). Zoning boundaries have been adjusted to line up with King County Assessor parcel lines that were improved in 2006 and 2007. Slivers and gaps will appear if this zoning layer is overlaid with historical zoning layers. The geometry of this data derives from KC parcel data which is updated quarterly. Then it was intersected with the existing zoning data to trasfer the attribute.Incorporated in February 1990, the City of SeaTac is located in the Pacific Northwest, approximately midway between the cities of Seattle and Tacoma in the State of Washington. SeaTac is a vibrant community, economically strong, environmentally sensitive, and people-oriented. The City boundaries surround the Seattle-Tacoma International Airport, (approximately 3 square miles in area) which is owned and operated by the Port of Seattle.

A general-pupose basemap designed to support a wide variety of web-based mapping needs. Through its countywide display of highways and streets, waterbodies, incorporated cities, and parks, the map is suitable as a stand-alone, general-reference map and as a base for thematic data display using operational map overlays. The map was designed specifically for use in ArcGIS Server applications, with scale-dependent layers and label classes customized for the Google/Bing Web Mercator tiling scheme, but it is also useful as a "quick-and-dirty" basemap for other map projects (although as a cached map service the map content is unalterable).
