In most cases, properties are bordered by both private or public property and one or more roadways, or even railroads.
However, the proximity of junctions, crossroads, junctions and intersections between several roads or railroads must be taken into consideration. The same applies to cable cars and ski lifts.
River, sea and air traffic routes are subject to their own easements.
The properties may be crossed by various energy and fluid transport facilities, or be adjacent to mines, quarries and military installations. They are therefore subject to special easements.
Areas protected against foreseeable natural hazards, such as floods and forest fires, also give rise to easements.
Plantations must not cause excessive disturbance. The spread of their roots can cause damage to neighbouring buildings and walls and hinder the proper development of plantations. Shading caused by branches must not be excessive, nor must the inconvenience of collecting leaves that have fallen on a neighbor's property.
Road safety must not be compromised by a lack of visibility caused by plantings that are too close or too high. Roots must not lift the road surface or its appurtenances.
Furthermore, vegetation must not encourage forest fires or impede the flow of water during floods.
