This Section of the County Website represents the ongoing work of the Calaveras County GIS Committee to develop a more efficient and user friendly system for accessing and distributing County information. The GIS Project was started through the cooperative effort of The City of Angels Camp, The Calaveras County Water District, The Calaveras Council of Governments, and the County of Calaveras. This joint effort has been formalized in the form of a Memorandum of Understanding (MOU), signed by each of these four participants. The MOU outlines an agreement between the participants to share GIS data openly.

Virtually all of the information gathered and used by the county can benefit by being linked to spatial data. The GIS will further be used to distribute the county datasets to the general public within the constructs of the MOU.

Frequently Asked Questions

Parcel Information Retrieval

This is the primary GIS tool.  It should provide most of the functions the tools below can provide.

Calaveras Co. Flood Zone Locator (larger viewing tool)

This application provides information to determine if a parcel is in, or near, a flood plain. In using this application it is important to keep in mind the accuracy of the data. The FEMA Flood Plain layer is only accurate to +/- 50 ft or so, and our Parcel layer varies in accuracy from +/- 10 ft to +/- 700 ft. This means, for example, that if you find a parcel is in, or out, of a flood plain by a few hundred feet you can not say for sure if it really is in or out of the flood plain.

You must contact the local Building Department before basing any legal decision on this information. We will be improving the Parcel layer over time, but there will always be some factor of uncertainty.

Aerial Imagery (includes B/W and Topos) (larger viewing tool)

Provides Aerial Imagery of Calaveras County (includes road and parcel layers which can be disabled). The imagery consists of 1998, 2002, 2004 and 2006 aerial image tiles which have been joined to form a complete image of the county. The Aerial photos do not become visible (turn on) until you have zoomed in.

1998 USGS B&W are black and white, and are at a lower resolution.

Also available here are the USGS Topo Maps of Calaveras County. The layer has been developed from scanned paper Topo maps which have been joined to form a complete topo map of the county.

Uncheck the aerials layers and check the topo layer to view topos.

If selected, the parcel layer does not become visible (turn on) until you zoom in.
