Fundamentals of Surveying (FS) Practice Exam

In most states, the boundary between navigable tidal waters and bordering uplands is the line of the:

1. Mean sea level

2. Highest tide in the winter

3. Mean high water

4. Mean low water

The correct answer is: Mean high water

The boundary between navigable tidal waters and the bordering uplands is established at the line of mean high water. This point is important in property law and environmental regulations, as it delineates the ownership and rights between private landowners and public entities regarding tidal water usage. Mean high water is defined as the average height of the high waters over a specific time period, often taking into account variations due to weather conditions and seasonal changes. This line helps to identify the area that is subject to tidal influence and is significant for determining where public rights may apply, especially concerning access to waterways and conservation efforts. In contrast, mean sea level serves as a baseline for measuring elevations but does not accurately represent the specific boundary needed in this context. The highest tide in the winter is not a standard reference for establishing a consistent boundary, as tidal heights can fluctuate seasonally. Similarly, mean low water provides a different point of reference that would not delineate the boundary appropriately in terms of uplands in relation to navigable waters. Thus, mean high water is the most suitable choice for defining this boundary.
