Move the cursor and click on Planning & Environmental Resources. Move the cursor to the GIS box, another drop-down box will appear – click on GIS Web Map Application. Bookmark page for future use.

When a map appears, click inside the search box on the top left corner of the screen. Enter RE Number format: 00000000-000000 or AK Number format: 0000000) and click the “search" button or hit the “Enter” key on your keyboard.

*To find the RE Number or AK Number: Search the Monroe County Property Appraiser website with a property address or a name.


An aerial view of the property will appear along with an Info Window containing basic information about the property. On the right side of the page, in the box labeled GIS Layers under “Operational Layers” is a box labeled “Planning_Env.” Click on the small gray arrow to the left of the box, see the example below, to enable the Map Layers.


Below the ‘Planning_Env’ box is the list of available Map Layers. All map layers are ‘Scale-Dependent’ – they are disabled (grayed-out) beyond a certain map scale. ‘Zooming-in’ (use + or – signs at the top left corner of the screen) on the map frame will enable/activate the layers. Each layer can be individually toggled (checking the layer’s box) to display in the map frame.


Clicking on the small gray arrow will expand that layer’s legend (color-coded symbols).
