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.

Waukesha County ArcGIS Online OrganizationWaukesha County AGOL is a mapping platform which allows residents, County employees, and the public display county data through maps. Certain functions are accessible only with authorized credentials.

This site allows for browsing, querying and downloading Waukesha County GIS data.

If you are interested in building a new home, please use the New Home Checklist to help you identify the zoning provisions that apply to your property, including dimensional standards, site limitations and other considerations. The checklist will direct you to a new home mapping tool. See planning and zoning resources for actual check list. https://www.waukeshacounty.gov/landandparks/planning-and-zoning/new-home-zoning-resources/

The Waukesha County Park and Open Space Plan was adopted by the County Board on March 27, 2018 and is intended to act as a guide for the acquisition, preservation, development and management of park, recreation and open space lands in the County.

For the full plan text, see https://www.waukeshacounty.gov/globalassets/parks--land-use/park-system/park-and-open-space-plan/2018-final-pos-plan-update-final.pdf for more information.

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.

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.

1. Description

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.

Percent Slope

1. Description

   Soil polygons displayed, by color, according to the SLOPE_PERCENT value field of the soils database. Slope percentages were combined to create a range.

Stormwater Infiltration Potential

1. Description

   Stormwater Infiltration Potential within Waukesha County.

Land Capability Class

1. Description

   Soil polygons displayed according to the LAND_CAPABILITY_CLASS value field of the soils database. Capability classes were then grouped and color coded.

Soils Parent Material

1. Description

   This layer shows generalized soil composition groups based on parent material

Surface Textures

1. Description

   Soil polygons displayed, by color, according to the SURFACE_TEXTURE value field of the soils database. Sandy Soils = Course Sand, Fine Sand, Fine Sandy Loam, Gravelly Sand and Loamy Sand. Loamy Soils = Loam and Sandy Loam. Silty Loam Soils = Silt Loam. Clayey Soils = Clay, Silty Clay and Silty Clay Loam. Muck Soils = Muck.

This map shows lakes, rivers, and streams for Waukesha County as acquired from year 2000 aerial photography. Also available for display are WI DNR hydro layers as well as some Waukesha County Land Resource layers.

This data set consists of digital aerial photo images obtained from 1"=1667' scale black and-white negatives aquired in the spring of 1980. The pixel resolution of the 400-scale imagery is one foot on the ground. The images are in a single county-wide file in MrSID compressed format with the accompanying sid "world" (sdw) files.

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.
