Description: The 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.

Description: This data set is a compilation of tax code area boundaries in Snohomish County, Washington. Tax code areas are formed from a composite of special purpose district boundaries such as cities, fire districts, school districts, etc. Tax code areas represent areas with a uniform tax (levy) rate for that area. The boundaries of the present data set are compiled from data sets for many of the taxing districts that were compiled from legal descriptions for each annexation from the original incorporation onward. Legal descriptions were interpreted without assumption of intent or bias from any pre-existing maps. Spatial registration conforms to features in the Snohomish County parcel data set. For areas where special purpose district boundaries have not been converted, the boundaries were taken from a manually maintained atlas.

The original Wetlands information was compiled in 8-86 from field studies conducted by Snohomish County Biologists. These polygons were created through Heads-up digitizing a scanned image of the original hard-copy (Mylar) maps. The sections were registered to the survey control points used in the Integrated Land Records database. Stream information was not included at this time, as funding was provided only for wetland conversion. Original scanned images exist as well as the initial registered images, which may be used for future conversion of the non-converted data.</SPAN></P><P><SPAN>QAQC standards were developed to meet designations defined by the Buildable Lands Fund.

Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This data set represents the extent, approximate location and type of wetlands and deepwater habitats in the United States and its Territories. These data delineate the areal extent of wetlands and surface waters as defined by Cowardin et al. (1979). The National Wetlands Inventory - Version 2, Surface Waters and Wetlands Inventory was derived by retaining the wetland and deepwater polygons that compose the NWI digital wetlands spatial data layer and reintroducing any linear wetland or surface water features that were orphaned from the original NWI hard copy maps by converting them to narrow polygonal features. Additionally, the data are supplemented with hydrography data, buffered to become polygonal features, as a secondary source for any single-line stream features not mapped by the NWI and to complete segmented connections. Wetland mapping conducted in WA, OR, CA, NV and ID after 2012 and most other projects mapped after 2015 were mapped to include all surface water features and are not derived data. The linear hydrography dataset used to derive Version 2 was the U.S. Geological Survey's National Hydrography Dataset (NHD). Specific information on the NHD version used to derive Version 2 and where Version 2 was mapped can be found in the 'comments' field of the Wetlands_Project_Metadata feature class. Certain wetland habitats are excluded from the National mapping program because of the limitations of aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and near shore coastal waters. Some deepwater reef communities (coral or tuberficid worm reefs) have also been excluded from the inventory. These habitats, because of their depth, go undetected by aerial imagery. By policy, the Service also excludes certain types of "farmed wetlands" as may be defined by the Food Security Act or that do not coincide with the Cowardin et al. definition. Contact the Service's Regional Wetland Coordinator for additional information on what types of farmed wetlands are included on wetland maps. This dataset should be used in conjunction with the Wetlands_Project_Metadata layer, which contains project specific wetlands mapping procedures and information on dates, scales and emulsion of imagery used to map the wetlands within specific project boundaries.</SPAN></P></DIV></DIV></DIV>
