The Historic Resources Committee was originally established in 1982 as the Archives Committee. In 1994, the name was changed to the Historic Resources Committee when the Historic Element was added to the General Plan. In 2024, this Committee was converted to a Working Group.
The chief purpose of the Historic Resources Working Group is to maintain an archive of historic documents, maps and photographs for the residents of the Portola Valley region to enjoy (one may visit the archive at the Portola Valley Library).
