DATUM.--Land-surface datum is 1,463.83 ft above North American Vertical Datum of 1988. Measuring point: Top of casing, 2.23 ft above land-surface datum, Sep. 21, 2012 to present; File marks on 2" PVC pipe, 2.22 ft above land-surface datum, Mar. 6, 2018 to Oct. 15, 2020; File marks on 2" PVC pipe, 2.21 ft above land-surface datum, Oct. 15, 2020 to present.
