Westfield -- 07090 -- is a destination community, a wonderful suburb; however, it is more like 30 miles from the Hudson. Summit NJ is 24 miles from the Hudson. In terms of a stellar community in Central NJ, these are 2 of the best. Millburn is another wonderful town, about 26 miles.
Frankly, to be in a good community only 20 miles from the Hudson, you might need to look in Bergen County -- north Jersey.
If you would like to discuss, feel free to call me on 732-423-2792.
