Welcome to Survey Division's Benchmark Retrieval 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 benchmarks. 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.

Historical (archival) additional county benchmarks (County Engineer & Flood Control). These benchmarks can be researched if the benchmark number is known. Contact the Public Records Counter, contact information provided below.

To download a quad, just hover 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.
