In a corporative effort the Contra Costa County Surveyor Section and the Mount Diablo Surveyors Historical Society have mounted a joint display case for public viewing of historicl surveying equipment. The display case is in the front lobby of the Contra Costa County Public Works Department building. As you enter through the front doors, the case is on your left, before the lobby widens out. MDSHS members Keith Nofield, PLS and Ray Zwemmer, PLS set up this display some years ago. The items in the case on the left is entirely County items, while the case on the right is MDSHS property.

The County Surveyor Section includes Surveys, Right of Way Engineering, and Map Checking. The Survey Section provides field and office support including topographic and property surveys, data reduction, surface generation, and construction staking on projects. The Right of Way Engineering Section prepares right of way maps and legal descriptions for property acquisitions. The Map Checking Section reviews Final Maps, Parcel Maps, Records of Survey and Corner Records for compliance with appropriate laws pertaining to each map.

The Records Section staff indexes and maintains records for the Public Works Department. They also compile and update road logs by adding mileage of newly accepted roads and deleting mileage removed from County control. The staff also provides assistance by researching and answering questions regarding County roads and surveys, and researching records and drawings.
