Click here to access the Interactive Data Viewer for the preliminary Adelaida study area. This is an interactive mapping system to help you navigate around the study area by panning, zooming, or searching for a specific parcel or street address that you would like to locate. There are different map layers that can be shown and superimposed in this interactive mapping system such as boundaries of groundwater basins, cities, roads, or other entities by checking the layer names indicated on the left panel layer menu.

To search and locate a specific APN or street address on the map:

  1. Enter either the nine-digit parcel number (APN) including hyphens or the complete street address in the “Search...” bar on the upper right-hand corner of the map screen and then click on the search button to locate it. The APN or street address that you just entered will appear on the left panel and a location marker will show up on the map to identify the location.
