House raising
House raising (house lifting, house jacking, barn jacking, building jacking) is the process of separating a building from its foundation and temporarily raising it with hydraulic screw jacks. The process is the first step in structure relocation in which the building is moved to a different location. House raising may also be a part of a renovation to build a foundation under an existing house or make a house larger by building a new floor level creating a two story house. Often employed in areas that are prone to flooding and storm damage, this process can be achieved through the use of either timber piles or helical piles. Once a house is raised and supported on cribbing, a new foundation can be constructed beneath it. After Hurricane Katrina and Hurricane Sandy large numbers of houses in parts of Louisiana, New York and New Jersey were raised to avoid future flooding.
Base fee
In law, a base fee is a freehold estate of inheritance which is limited or qualified by the existence of certain conditions. In modern property law the commonest example of a base fee is an estate created by a tenant in tail, not in possession, who bars the entail without the consent of the protector of the settlement. Any attempt to bar the entail without the consent of the Protector would only be partially successful. Though he bars his own issue (the rights of the future tenants in tail), he cannot bar any remainder or reversion, and the estate ("i.e." the "base fee") thus created is determinable on the failure of his issue in tail. The base fee can be defined as rights that would last for as long as the fee tail would have lasted, but which will end when the line of descent stipulated in the fee tail ran out.
