Data Dictionary, Shared Account Relate Document, Related DocumentThe Parcels data set is a thematic layer depicting current real property parcel boundaries within Snohomish County, Washington based on the legal descriptions contained in the assessment roll. Parcels in this data set are defined as real property entities that can be valued for the purpose of collecting taxes. Parcels include, but are not limited to land, buildings on leased land, mobile homes and condominium units. Parcels may overlap. Parcels such as condominium units and mobile homes that may occupy a single polygon are represented as non-planar features (regions) of the same geographic extent. The Parcels data set does not depict legal ownership boundaries nor does it represent legal building lots. Snohomish County does not maintain parcels for the complete geographic coverage of the county. There is no parcel fabric in much of the eastern mountainous area.

This polygon dataset is a compilation of all the townships in Snohomish County derived from the Public Land Survey System (PLSS) grid dataset. The PLSS grid is the master coverage of the PLSS maintained by the Assessor's Office. It contains linework and attribute information for townships and ranges. It is compiled from recorded surveys and plats, coordinates and linework supplied by private surveyors, Snohomish County Public Works Survey, cities, Washington State Department Of Natural Resources (DNR) and the United States Department of the Interior - Bureau of Land Management (BLM). Standard BLM methods are used to construct the aliquot grid. In coastal areas, the aliquot grid may not apply for many of the coastal sections, it has been constructed for the purposes of land title and defining map extents for automated routines.

description: Preliminary report on the geology of southern Snohomish County, Open File Report 73-1. The map area includes eighty-five square miles in South Snohomish County southeast of Everett, bounded on the west by Interstate 5, on the south by Highway 405 and the Snohomish-King County boundary, on the east and north by the Snohomish River floodplain. The purpose of the project is to provide a geologic map of the area at a scale which can be useful as a tool in urban planning. Since the project has been done in conjunction with the Snohomish County Planning Commission, hopefully, it will provide geologic data that will be useful to them in planning for future metropolitan and industrial growth. The geologic map will provide a basis for applying groundwater, seismic response, slope stability and engineering property studies to the area, all of which are important factors in today's urban and regional planning.; abstract: Preliminary report on the geology of southern Snohomish County, Open File Report 73-1.

Data DictionaryThe Lots data set is a thematic layer depicting legal lot boundaries such as formal plats, condominiums, short plats, etc. Lots are defined as real property entities that have gone through a formal review process through a county or city regulatory agency for the purpose of subdividing land into smaller legal building lots. Lots may overlap completely or partially. The Lots layer is not complete for any category of subdivision type as some lots may no longer have any relevance and are therefore not included in the data set.

Snohomish County adopted a Mineral Resource Lands (MRL) in Map 2 of the Future Land Use Map on February 1, 2006, designating and protecting land containing mineral resources of long-term significance. The MRL designation overlays other land use designations, and is intended to (1) limit mineral activity to areas within the MRL, and (2) restrict intense rural land uses within the MRL to preserve future access to the mineral resources. A 1999 mineral lands inventory identified 177,000 acres of mineral resources in Snohomish County. Of the 177,000 acres identified in the inventory, 131,000 acres are designated in the MRL. The MRL represents all of the mineral resource deposits in the county which meet the criteria for volume, quality, and extractability; are under county jurisdiction and are not slated for more intensive urban development; and are located in predominantly undeveloped, low density rural or forest areas where land use and environmental incompatibility issues have been addressed at a countywide level. Some of SCC 30.32C was amended by Amended Ord. 21-060 on 10/6/2021.

PSRC utilizes assessor data extracts for King, Kitsap, Pierce, and Snohomish counties to estimate housing development at the parcel level for each year in this time series. The methodology utilizes variables that identify Residential Uses, Number of Units, and Number of Buildings together with a Year Built variable to estimate new housing units built annually by structure type. The most current vintage of residential assessor records are then related back to a base year record set to determine what type of development took place on a given parcel. Development activity types tracked are: 'New Development', 'Redevelopment', and 'Rebuild/Remodels'. For Redevelopment and Rebuild/Remodels, base year unit counts are categorized as 'Demolitions' and subtracted from the inventory to calculate net change. The annual net housing unit estimates are summarized by county, jurisdiction, and census tract. The starting year in the time series will vary by county due to base year datasets differing from county to county. The time series for each county is as follows: King County: 2010-2023 Kitsap County: 2010-2023 Pierce County: 2012-2023 Snohomish County: 2011-2023
A new time series will be processed and published each year. Please note the estimates may shift from version to version due to updates in the data inputs and methodology refinements. Group Quarter Facilities are omitted from the final estimates. Unit counts for Mobile Home Parks are held constant except when an existing park is closed or redeveloped or a new park is opened. The 'Single-Family Attached' structure type category is defined in each county by the following: King: 'Townhouse Plat' present use category in the parcel table Kitsap: House type code '146 Townhouse' in the dwellings table Pierce: Built-As IDs 61, 65, and 68 in the improvements built-as table Snohomish: Property Class Codes 116 and 142 in the master table Missing Unit/Building Counts Housing unit and building counts are not available in the Snohomish County assessor datasets. Unit counts for single family parcels were assumed to = 1. Unit counts for multi-family parcels were populated by using utility hookup counts from the Snohomish County Public Utilities District (PUD). Building counts were populated by using a mix of utility customer property data and structure type information. Kitsap: Unit counts are accessed through a supplemental data request to the Kitsap County Department of Community Development
