In early 2010 a multi-year planimetric data collection project was completed and the data incorporated into the Village of Riverside GIS (Geographic Information System) database. Information collected in this process included features such as roadways, sidewalks, driveways, recreation areas, curbs, retention walls, among many other things.

This new information provides a great resource of real world features to incorporate into existing and future map products. Another advantage of having this much new GIS data is the ability to perform analysis. And one of the first analysis projects was to determine impervious surfaces throughout the village. The evaluation consisted of comparing all impervious surfaces such as driveways, buildings, etc. against the existing parcel information and then calculating the percentage of each property that was improved. Looking at the final map output one can quickly understand where the most improved areas are in the village and this information can support decisions such as evaluating who would be most affected by initiation of a storm water fee.
