7.040 Standard for Determining Elevations – Vertical Datum Defined.

The word Datum wherever used in the City of Manitowoc shall mean “North American Vertical Datum of 1988” (NAVD88).

The NAVD88 elevation of 578.0 equals the low water datum for Lake Michigan of elevation 577.5 International Great Lakes Datum (IGLD85).

This NAVD88 replaces the United States Coastal and Geodetic Survey Datum of 1929 originally adopted by the City in 1969. Prior to that a local City datum was in use, referencing Lake Michigan low water datum – elevation 100.0.

This section shall not govern the meaning of the expression Datum wherever any other meaning is by the context clearly expressed, nor shall this section effect a change or alteration in the established grade of any street in said City.
