County Maintained Road System

This webpage is devoted to historical documents of the County Maintained Road System. The County Maintained Road System includes all of the roads in the County that are maintained by the Department of Public Works. Roads not listed in most current version of the road log are maintained by either State of California (Caltrans), Bureau of Land Management, National Park Service, US Forest Service, an incorporated City (Arcata, Blue Lake, Eureka, Ferndale, Fortuna, Rio Dell, Trinidad), a Tribe, or are privately maintained pursuant to Civil Code 845.

Documents on this webpage fall into four (4) categories:

  1. Road Numbering System: In 1968 the current road numbering system was established. Documents establishing and explaining the current the road numbering system can be found here.  Information concerning the prior road numbering system is not available. 
  2. Road Logs: Scans were made of the various road logs that have been found in the Department of Public Works files.  It does not appear that road logs were published for every year.  The scans have been made from the best available copy.  Some scans may be difficult to read because the original document is difficult to read. The road logs are listed in chronological order from oldest to newest.
  3. Road Maps:  Scans were made of the various road maps that have been found in the Department of Public Works files.  Maps are known to have errors. The Department does not maintain a list of known errors. The maps have not been added to this webpage as of this date. Contact 707.445.7205 for the road maps.
  4. Board of Supervisors Agenda Items:  The County maintained road mileage is affected by actions of the Board of Supervisors to add or remove roads from the road system.  Scans were made of the various documents found in the Department of Public Works files.  The scans have been made from the best available copy. Some scans may be difficult to read because the original document is difficult to read. The agenda items have not been added to this webpage as of this date. Contact 707.445.7205 for agenda items.
