This layer represents the tax parcels in King County. This layer also includes place-holder polygons which do not represent tax parcels but are included to identify platted and unplatted land descriptions. The layer includes stacked polygon geometry for undivided interest and vertical parcels. King County parcel numbers may include leading zeros in PIN, Major or Minor. The data is created for Assessment purposes and is not guaranteed to represent accurate measurements or to reflect salability or buildability of a tax parcel. These tax parcel boundaries represent general location only, and they should not be considered or used as the exact legal parcel boundary location. Do not use for survey purposes.

Here you will find a selection of maps that have been produced by various King County departments and divisions and are hosted on the KCGIS Center website.

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.

A parcel based layer providing an address based on spatial overlay where available, and a range of other property related attributes. To produce PARCEL_ADDRESS_AREA , PARCEL_AREA is spatially joined to ADDRESS_POINT to obtain address attributes, KROLLIDX_AREA to obtain a Kroll page reference, INTRMPAA_AREA to obtain potential annexation area attributes, and PLSS_AREA to obtain section-township-range. It is also joined on PIN to RPACCT_EXTR, PARCEL_EXTR, CONDOCOMPLEX_EXTR, and CONDOUNIT_EXTR to obtain property and assessment related attributes from the KC Assessor office. In many cases multiple addresses are spatially coincident with one parcel, and in those cases only one arbitrarily selected address is used to populate the address attribute information.

The purpose of this project is to find, count and map onsite septic system (OSS) served parcels in King County. Additionally, sewer connected parcels were also identified to exclude them from expected OSS parcels. The starting base layer was a parcel layer for all of King County (Plibrary.PROPERTY.parcel_area) from about September of 2015. The parcel base layer was updated in 2020. Project staff used various means to identify and catalogue sewer connected, OSS served, vacant and other identified parcels for all of King County.

KC streets derived from the cadastral database where lines represent the mid-point of the parcel right-of-way. Because it's parcel based, lines will not always align with the ortho photos. A feature in ST_ADDRESS should exist if there is a property with a valid address. A property such as an apartment or condo complex may have many streets within the property but only one street will be shown in ST_ADDRESS, containing the site address. Use TRANS_NETWORK when the lines should more closely match the ortho photos.

This map shows participating parcels for current use taxation programs in King County, WA that offer an incentive (a property tax reduction) to landowner to voluntarily preserve open space, farmland or forestland on their property.

Together with partners and willing landowners, the Land Conservation Initiative aims to protect 65,000 acres of land in King County before 2050, of which 45,000 acres are targeted for easement or fee acquisition. This layer tracks parcels acquired either by King County or with grant funding assistance from King County. This layer does not indicate properties available for public access. Many conservation easements are recorded on private property and are not open to the public but instead are protected to support environmental, resiliency, or health goals. Properties available for recreation can be viewed in the layer park_area which is available in the recreation category.

Dashboard showing the residential housing unit characteristics across the City of Seattle. Data is from the King County Assessor Office and is compiled by the City of Seattle planning office.King County Assessor (KCA) data has been compiled to create a dataset of unit types and sizes by tax parcel identification number (PIN). City of Seattle spatial overlay data has been assigned through geographic overlay processes. This data is updated periodically and is used to support the analytical and reporting functions of the City of Seattle long-range and policy planning office.The map includes attribute data from the King County Assessor tables that characterize the use, number of units, number of bedrooms and building square footage (net) for all buildings that indicate a residential use. Due to the way KCA reports the data, some records are for all units within individual buildings (residential and commercial building records), while other records are for the combination of unit type and number of bedrooms (apartment and condominium records) on a particular property (called complex in the table). Therefore there may be many records for any given PIN.Some unit counts and type assignments have been imputed based on other data to allow characterization of the complete data set. Other fields have been added to aid in classification for planning purposes such as the complex category. Every effort is made to characterize the data accurately. Spatial overlay data for various City of Seattle reporting geographies are assigned as "majority rules" by land area in cases where multiple geographies span a single tax parcel.KCA tax parcels are created by King County for property tax assessment and collection and may not match development sites as defined by the City of Seattle (single buildings may span multiple tax parcels), may be stacked on top of each other to represent undivided interest and vertical parcels, or may be made up of several sites that are not contiguous. Attributes include parcel centroid locations in latitude/longitude and Washington State Plane X,Y. To get polygon representation of the data please see King County's open data page for parcels and join this table through the PIN field. Please be aware that the King County Assessor site address is not a postal address and may not match other address sources for the same property such as postal, utility billing, and permitting.See the detailed data dictionary for more information.
