The road to the South of this address actually continues upward to this address (which should be listed as 1005 Westside Rd, Healdsburg, CA 95448).  I entered some rough averaged GPX data here and some photos here (https://www.google.com/maps/d/u/1/edit?mid=1SXoSf8oAlIb6l7EpU2-24VKNfk5j2if1&usp=sharing) but my cell phone GPS isn't super accurate so I wasn't sure how to update the boundaries of the road taking that into account.
