Topic	Sediment: Road Densities for Laguna Calwaters

 

Caption:  The chart above shows a summary of road densities in miles per square mile for the Laguna Calwater Planning Watersheds. All Calwater Planning Watersheds have road densities exceeding properly functioning condition according to the National Marine Fisheries Service (1996), which is less than 3 miles per square mile, a value shown for reference. Cedarholm, et. al. (1981) suggests that road densities should not exceed 1.6 mi/sq. mi. High road densities are mainly associated with urban areas. Road data originates from 1:24,000 scale topographic maps and under represent road densities, especially in urban and timber harvest areas. Roads densities are calculated by KRIS IFR staff in Arc Info. See Map for a map layer of basin wide roads. See InfoLinks for more information.
