Map sites display properly at screen resolutions 1280 by 800 or higher.  If parts of the map are not displaying your screen resolution is probably too low e.g., 800 x 600.  Popup blockers must be turned off for the sites to function. 

The next three links below take you to the same website but with different "map services".  Once there you can toggle between the map services using the pull-down menu below the map.  Learn more here.

Critical Areas - View critical area (environmentally sensitive) layers along with base map data.   Note: Most of the environmental layers (e.g., wetlands, shoreline, FEMA, soils, etc.) were not produced by Jefferson County.  These layers are at a scale of 1:24,000 or less and can be off from 40 feet to a few hundred feet.  They should only be considered as a highly generalized reference when zoomed in closer than 1:24,000 or when viewed with the parcel layer.
