The Tidelands claims line depicts areas now or formerly flowed at or below mean high tide. Since the mean high water line may change because of rises in sea level, the line does not represent the current mean high water line. Rather it depicts the mean high water line at the time of mapping and the historic mean high water line predating artificial alterations. The Tidelands claim line was originally mapped and promulgated on 1628 individual maps produced at a scale of 1:2400. The individual maps were subsequently merged together to produce the tidelands region shapefiles presented here. These region files were created to be used only as resource data sets to more easily identify those areas claimed under the tidelands program. They are not to be considered the official tidelands claim lines. Only the actual promulgated tidelands maps, at the production scale of 1:2400, can be used to locate the legally valid tidelands riparian claim line.
