GIS Maps and Data

This page is where you will find links to view our many interactive and reference maps, and to download GIS (Geographic Information System) datasets. We provide many interactive maps, each having a specific function, to aid you in understanding both the County or a particular piece of real property. We also provide most of the data upon which these interactive maps are built, either as direct downloads to use in your own applications and/or as services, which you may utilize when building your own web-based applications.

Interactive Maps

Our interactive mapping apps are theme-based. Among them include apps that highlight Development Proposals, Flood and Geologic Hazards, and our all-inclusive Interactive Property Assessment app.

Reference Maps

Our reference maps are useful for many purposes; however, by their very nature, they are static, and are at risk of being outdated. These maps are refreshed periodically. Always confirm your understanding of any particular reference map by using either an interactive map, or checking in with the Planning Office.
