This application is intended for users who need a lot of information about a parcel or area in Waukesha County. It is heavily focused on land use, zoning, and property ownership. Check the Metadata button for more information on each individual layer. For information on the website tools or troubleshooting, choose one of the topics on the Help ribbon to the right. For specific property assessment information, please contact the local municipality that covers your area of interest.

Open-file report; contains unpublished data that has not yet been peer-reviewed.

The Color Parcel Basemap provides a consumer representation of parcel information that can be used without the aerial photo. The layers in the map provide context for multiple workflows, such as editing data or producing web maps and include roads, major facilities and landmarks, water features, parcels, and boundaries. It is compiled from mapping activities performed in Waukesha County as well as the Cities of Brookfield, Muskego, New Berlin, and Waukesha. Parcel discrepancies from the four municipalities should be directed to City staff for correction.

Allows for querying a quarter section and downloading a black and white quarter-section parcel map in PDF format.

This data set is a digital soil survey and generally is the most detailed level of soil geographic data developed by the National Cooperative Soil Survey. The information was prepared by digitizing maps, by compiling information onto a planimetric correct base and digitizing, or by revising digitized maps using remotely sensed and other information.

This data set consists of georeferenced digital map data and computerized attribute data. The map data are in a soil survey area extent format and include a detailed, field verified inventory of soils and miscellaneous areas that normally occur in a repeatable pattern on the landscape and that can be cartographically shown at the scale mapped. A special soil features layer (point and line features) is optional. This layer displays the location of features too small to delineate at the mapping scale, but they are large enough and contrasting enough to significantly influence use and management. The soil map units are linked to attributes in the National Soil Information System relational database, which gives the proportionate extent of the component soils and their properties.

Building Limitations

1. Description

   A definition query was performed on each of the limitations using the soils database. In order to avoid duplication of features from three soil types (Pm, RkE & RlA), the erase function was used from ArcToolbox. By erasing the Depth to Bedrock from the the <1 Foot to Water Table, the result of that process erased from the <3 Feet to Water Table and finally that result erased from the Percent Slope, a heirarchy was established. In order of priority: <1 Foot to Water Table, <3 Feet to Water Table, Shallow Bedrock and Slopes >12%.

Depth to Seasonal High Water Table

1. Description

   Soil polygons displayed, by color, according to the DEPTH_TO_WATER_TABLE value field of the soils database. Depths were combined to create a specific range.

Hydric Classification

1. Description

   Soil polygons displayed according to the HYDRIC_CODE value field of the soils database. Hydric and Hydric Inclusions were then color coded.

Hydrologic Soil Group (Native Condition)

1. Description

   Soil polygons displayed according to the HYDRIC_SOIL_GROUP value field of the soils database. The different soil groups were then color coded. Dual Hydrologic Groups (A/D, B/D & C/D) represent drained and undrained conditions. D was designated for these groups to represent the native condition of the soil.

Application allows the DNR to view current and past permits for their proximity to sensitive lands. It has a couple of tools that assist, such as turning all the DNR layers on/off and one that finds the nearest sensitive areas to a given permit.

Waukesha County Public Land Survey System PLSS
