The Public Land Survey System (PLSS) Grid - Line is linework derived from the master coverage of the PLSS maintained by the Assessor's Office. This dataset only contains linework and attribute information for townships, ranges, sections, quarter sections and quarter quarter sections and government lot lines. 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.
