The Waukesha County GIS Internet Mapping Site was developed to provide county departments, municipalities, and the public with geographic information for use in land use planning, zoning, and other activities. The site is periodically taken offline for data updates, software maintenance, etc. All attempts will be made to limit this downtime to off-business hours (8:00 AM-4:30 PM, Mon-Fri).
