Mapping and Geographic Information Services


The Department of Public Works (DPW) has a Geographic Information System (GIS) function for collecting and maintaining geographic data. The term GIS is applied loosely to a large group of interrelated technologies. For local governments, GIS is computer technology that associates geographic data (locations of man-made and natural features) and attribute data (names, addresses, classifications, and other values stored in databases) to generate visual maps and reports. GIS allows the user to interact with multiple layers of data within a map. A series of e-books about GIS can be found here.

Public Maps & Data

All available GIS data for download or use can be accessed from our Open Maps page. To access the city’s web mapping applications please visit our Map Gallery page. 

Impervious Surface Mapping

The utility fee is based on the amount of impervious surface (e.g. roof, driveway, walkway, patio, etc.) your site has. For each 200 square feet of impervious surface the cost is $18.36.

To view your property's impervious surface please visit the impervious surface mapping application.

If you believe your property's impervious surface has been mapped incorrectly please submit a Stormwater Utility Fee Adjustment form.
