to be impractical because of the size, shape, location, access, topography,
drainage, or other physical features of the land and that such dedication
would adversely affect the subdivision and land development and its
future residents or occupants or that there is no land area within
the proposed subdivision which is practical for dedication to the
public because of size, access, topography, or other physical characteristics.
