Identification Information

Originator Washington County Survey and Land Management Division
Title County and Municipal boundary data set, Washington County, Minnesota
Abstract This data set contains exterior boundary lines for each minor civil division (MCD) within Washington County. The exterior boundary for each MCD was derived from the compilation of all annexations. The exterior boundary lines for each MCD were individually joined to form a single MCD coverage. Each MCD polygon contains attribute information about the MCD.
Purpose To provide accurate boundaries for each municipality within Washington County.
Time Period of Content Date
Currentness Reference MCD exterior boundaries and similar recorded information is current to 30 days from recording or official entry in county record system.
Progress Complete
Maintenance and Update Frequency Monthly
Spatial Extent of Data MCD boundaries are shown for the entire area of Washington County.
Bounding Coordinates -93.017

Access Constraints The data set is available to anyone.
Use Constraints The digital map is furnished on an AS IS basis, without any support whatsoever, and without representation or warranty, including but not in any manner limited to fitness, merchantability and completeness. The information is neither a legally recorded map nor a survey and is not intended to be used as one. The information is a compilation of records, information, and data from various City, County and State offices and other sources and should be used for reference only. No representation is made that the features presented accurately reflect true locations. Washington County or any other entity from which data was obtained assumes no liability for any errors or omissions herein. If discrepancies are found, contact the Washington County Surveyor's Office.

Data Quality Information - - - - - - Go back to top

Attribute Accuracy Attribute information is tested by manual comparison with the source document.
Logical Consistency Exterior boundary, Annexation boundary, and County boundary coverages are examined to remove all overshoots, unwanted intersections; insure polygons are closed; and to see that there are no missing or duplicate polygon labels. Each symbolic layer is individually examined for completeness. There is no line duplication in exterior or annexation coverages. MCD's with detached or non-contiguous units (polygons) have the same polygon link/label code in each of their units.
Completeness Completeness in the checking process is examined through the examination and comparison of all detail collected by County Staff. Sources used included: City Clerks, County Auditor's Office, Washington County Historical Courthouse, MN State Historical Society, Secretary of State, Minnesota Municipal Board, and MNDOT.
Horizontal Positional Accuracy Boundaries shown that coincide with hydrological features or those that have generalized definitions with little supporting detail of their location are digitized from digital aerial orthophotos. Boundaries defined as center of main channel on Mississippi and St. Croix Rivers are approximations only (source U.S.G.S. quadrangle maps). All other boundary segments are generated by coordinate geometry based on a framework of accurately located PLSS corner positions. Legal boundary definitions were interpreted and analyzed according to records available and are not based on field survey. The nature of these definitions present situations where documents of record may not coincide with known ground position or that their ambiguity makes it difficult to identify precise ground location. As a result, caution is necessary in use of the municipal boundary data when using it in site specific applications. For more information see the report noted in Lineage below or contact the Washington County Survey and Land Management Division.
Vertical Positional Accuracy N/A
Lineage MCD boundary locations are derived from interpreting legal descriptions of incorporations, annexations and other various orders and ordinances. These documents range in date from 1840's through the present. The boundaries were derived using coordinate geometry software whenever possible and drawn with AutoCAD/ArcGIS software to create the line, polygons and attribute information. The boundary line location process used information available from the parcel database. Upon completing the drawing of all features, a thorough check was made using a prescribed checklist. The limits of each MCD were compared with adjoining MCD boundaries for discrepancies. Any discrepancies found were noted and indexed by MCD.
