1.7. Partial Acquisitions. There are many situations in which a client agency is only acquiring a part of a larger parcel. This can occur when the client agency is acquiring an interest less than the fee simple, such as an easement, water rights, subsurface rights, or air rights. This can also occur when the agency is acquiring the fee interest in only a portion of a larger parcel. This section of the Standards addresses the appraisal requirements under these circumstances.
