(2) The department shall not acquire, through the exercise of the power of eminent domain, scenic easements in any lands situated within the boundaries of the Willamette River Greenway that are devoted to farm use on October 5, 1973, while such lands remain devoted to farm use. Upon a change in the use of any such lands from farm use, the department may acquire scenic easements in such lands as provided in subsection (1) of this section. Nothing in this subsection is intended to limit the power of the department to acquire, by any means other than the exercise of the power of eminent domain, a scenic easement on lands described in this subsection while such lands are devoted to such farm use. For the purpose of this subsection, "farm use" has the meaning given that term in ORS 215.203 (2).

(3) Each scenic easement acquired under subsection (1) of this section shall:

(a) Specify the use of the land existing on the date of the acquisition of the easement and permit the continuation of such use while the land is subject to such easement.

(b) With respect to scenic easements acquired through the exercise of the power of eminent domain, not provide for any rights of public access to or use of such lands under such easements.

(c) Provide that any subsequent farm use, as defined in ORS 215.203 (2), of the land subject to such easement is compatible with the purposes of the Willamette River Greenway and that any restrictions on the use of the land under such easement are suspended while such land is devoted to such farm use.

(d) Prevent the change in use of the lands subject to such easements except with the consent of the department and in accordance with the conditions imposed with such consent. The consent of the department and the conditions imposed therewith shall be in accordance with the intent and purposes of the Willamette River Greenway.

(4) In addition to a scenic easement acquired by the department under this section, the department may acquire, by any means other than the exercise of the power of eminent domain, a public easement providing for public access and use of such lands.

(5) At any time after the approval of the plan for the Willamette River Greenway or any segment thereof under ORS 390.322, the department may acquire, by any means other than the exercise of the power of eminent domain, lands or interests therein that are situated outside the boundaries of the Willamette River Greenway or the segment thereof as approved. Each such acquisition shall be designed to preserve the natural or scenic character of such lands in conjunction with the lands within the boundaries of the Willamette River Greenway. [1973 c.558 §6]
