Welcome to Survey Division's Bench Mark Retrieval System

We would appreciate your participation in our five-question survey on our Bench Mark system.
The Department of Public Works level net is composed of more than 1,700 miles (2,720 kilometers) of level circuits supporting in excess of 9,000 bench marks. To facilitate the adjustment, indexing and distribution of adjusted values to the network, the county territory was divided into 33 areas or "quads". For identification purposes each quad was given a name, for example , "Rosemead", "La Mirada", "Santa Fe", etc. Each quad's content includes index maps, county maps, abbreviation listings, etc. for each specific quad selected. The bench data provided is derived from the latest adjustments to date. NO historical data is provided.

Historical (archival) data can be acquired in two ways. By requesting "in person" from our Public Records Counter or via our fee based Optional Technical Research (OTR) program. Contact information is provided below.

To download a quad, just "hover" or move the cursor over the index map below and the various quad names will appear. Simply click on the desired quad to start the download automatically. The quads are provided individually in Adobe Acrobat (PDF) format. A version of Adobe Acrobat Reader appropriate for your system must be installed to view the files.
