    This is a map of 1:24,000 scale roads in the Santa Rosa sub-basin, displayed with sub-basins and a grayscale hillshade.  The central portion of the sub-basin is urbanized, 
with extremely high road densities.  The actual number of roads is under-represented in this map because the roads layer is based primarily on 1:24,000 scale topographic 
maps, which may be out-dated and tend to underestimate forest and ranch roads.  Highways 101 and 12 cross the sub-basin.  Data were provided by Legacy - The 
Landscape Connection.
