This new West Allis GeoWeb site is a complete redesign from the City's old GIS site and was designed to provide faster and easier access to City Parcel Information, as well as additional features that provide a rich Web Mapping experience. This site was developed using ESRI’s ArcGIS Server 9.3.1 and .NET Technology by City of West Allis staff. This site provides information regarding property values, ground features, land divisions, links to property taxes, and other data to the general public as well as the GIS professional community.

Help Documents: There is a link to documentation in each map that provides basic information on how to identify features, navigate the site using the specific tools offered, search for features, measure distances or areas, working with layers and map contents, along with information on retrieving and printing detailed data.
