Process description:
Created from lat/long table supplied from rating sheets that are in binders in the Napa County Conservation Department.  Other bridges were added from a list from the Office of Historic Preservation and a list from Trish Hornisher in Napa County Planning who said her list is supplied from CalTrans.  Locations were looked up either by lat/long or by creek/road intersection.  2005 aerial photos were used to visually put the bridge location in.
