arcgis 10.1 - Create a single connected polygon from multiple polygons

I am trying to create a single continuous (neighborhood) polygon from many tax block parcels. The Multipart to Singlepart GP tool does not accomplish the task since I need the polygon to be complete; i.e., without the spatial gaps between the parcels (see image). Any ideas of a quick and dirty way to accomplish this?

Answer

You could use the Aggregate Polygon GP Tool. You'll need an Advanced license though.
