Vertical datum definition

Vertical datum means either a fixed benchmark such as NAVD 88 or a site specific tidal datum such as mean high water, mean low water and mean sea level. NGVD 29 is based on the local mean sea level in 1929, which has changed over time. NAVD 88 is the official civilian vertical datum for surveying and mapping activities in the United States. Tidal datum, such as mean sea level (MSL) or mean high water (MHW), vary according to the specific location, and represent the mean heights observed over the national tidal datum epoch.
Vertical datum means the base elevation used for measuring height. It is calculated by adding the lowest elevation within five feet of an exterior wall to the highest elevation within five feet of an exterior wall on the same building, then dividing the result by two. The highest and lowest points shall be located on the historical or original grade, as determined by the building official.
Vertical datum means either a fixed benchmark such as NAVD 88
