GENERAL NOTES: 1. Tidal datums are referenced to NGVD of 1929. 2. Source of information Bureau of Survey and Mapping. Division of State Lands. Florida Department of Environmental Protection, for the National Tidal Datum Epoch of 1960-1978. 3. MLLW = mean lower low water MLW = mean low water MTL = mean tide level, which along the open coast = MSL = mean sea level; MHW = mean high water: MHHW = mean higher high water; MTR = mean range of tide (i'e.. MTR = MHW MLW). 30
