If you are developing in OpenLayers, you will want to use the OpenLayers ArcGIS93Rest class.

An example of your solution might look similar to the code below.

layer = new OpenLayers.Layer.ArcGIS93Rest(
    "Urban Growth Boundaries",
    "https://navigator.state.or.us/ArcGIS/rest/services/Framework/Admin_Bounds_WM/MapServer/export",
    {
        layers: "show:1",
        transparent: true
    },
    {
        isBaseLayer: false
    }
);
map.addLayer(layer);
