The claimants objective is a forced purchase of the affected property. SeeDukeminier & Krier, supra note 12, at 1168. 82 There are two types of nuisance: public nuisance and private nuisance. See id. at 74546. A private nuisance arises when ones actions result in an unreasonable interference with the use and enjoyment of anothers land. See id. at 745. A public nuisance is an act which interferes with the interests of the public at large. See id. at 74546. 83See Baker, 220 Cal.

It should be noted that the establishment of the element of adversity is independent of the stability of the operations of the airport (i.e., the use is adverse whether there is one flight per day or 100 flights per day). 217See Westchester II, 629 A.2d at 108788; Shipp, 431 S.W.2d at 86970.
