Notice Benchmark Data as of: April 25, 2012
DuPage County has upgraded its benchmark system from the North American Geodetic Vertical Datum of 1929 (NGVD29) to the North American Vertical Datum of 1988 (NAVD88).  Benchmarks in NGVD29 are no longer available.

Additional information / Benchmark Questions:

If you locate a benchmark in the field and it is not shown in the new NAVD88 benchmark web mapping application, it’s either an old NGVD29 benchmark (which is no longer supported or available from the County of DuPage) or it may be a local village benchmark.

If you find a disturbed or destroyed DuPage County benchmark in the field or have any questions please submit an email to benchmarks@dupageco.org
