Urban Service Areas are areas in and around existing communities that have the capacity to provide a full range of urban services, making them most suitable for development. USA boundaries represent the outer limits of planned urban growth over a long-term planning period. Amendments to the original areas expand services as communities grow. Service area boundaries are available to view and download on our Open Data Portal.
Urban and Limited Service Area Amendment Reviews
The Capital Area Regional Planning Commission and the Wisconsin Department of Natural Resources approve sewer extensions and sewage treatment facilities based on USA boundaries. USAs are also included in area plans so that local, regional, and state agency decisions can be coordinated, consistent and capable of achieving desired growth and development patterns.
Limited Service Areas are served with fewer or limited urban services, such as sanitary sewer. LSAs are intended for special or unique areas, or areas of existing development experiencing sewage disposal problems.
