Natural boundaries are those presented by nature. The types most commonly used for parcel definition are:
The banks of rivers and streams.
The edges of lakes, lagoons and the coastline.
Rarely are other natural features e.g. the edge of a swamp, the crest of a ridge or the edge or foot of a cliff, used to define boundaries
Survey definition of natural boundaries a boundary formed by a natural features must be surveyed in accordance with the provisions set out in the Surveying and Spatial Information Regulation 2012.Accretion and erosion the doctrine of accretion and erosion applies to boundaries of tidal lakes and both tidal and non-tidal streams and waterways. Tidal boundaries (MHWM) the position of the MHWM should be shown on the plan in the usual manner in accordance with provisons in Surveying and Spatial Information Regulation 2012. Non-tidal boundaries when a plan of survey includes a boundary fronting non-tidal lake or lagoon waters, the line of the bank that constitutes that boundary should be examined by the surveyor by comparing it by plot with the boundary as defined by the Crown survey. Landward boundaries of roads and reserves abutting waterways the boundary does not move parallel with any subsequent movement of the bank through accretion and/or erosion. Rivers forming NSW state boundaries special provisions apply when re-defining rivers that comprise part of the state border. Consents to natural boundaries most alterations to the position of the MHWM or the original definition of the bank of a non-tidal stream will require the consent of the relevant authority.
