There's a big park included in the new downtown (old mall) area.  I'm starting to sense that you really don't know what is going on in the new area.  It's progress, it's inevitable and it looks like it's going to be great!  Check it out http://www.downtownwestminster.us

As well as other projects going on in Westminster:
