Easements or rights-of-way operated, maintained, controlled or owned by irrigation districts, Carey act operating companies, nonprofit irrigation entities, lateral ditch associations, and drainage districts are essential for the operations of such irrigation and drainage entities. Accordingly, no person or entity shall cause or permit any encroachments onto the easements or rights-of-way, including any public or private roads, utilities, fences, gates, pipelines, structures, landscaping, trees, vegetation, or other construction or placement of objects, without the written permission of the irrigation district, Carey act operating company, nonprofit irrigation entity, lateral ditch association, or drainage district owning, operating, maintaining, or controlling the easement or right-of-way, in order to ensure that any such encroachments will not unreasonably or materially interfere with the use and enjoyment of the easement or right-of-way. Encroachments of any kind placed in such easement or right-of-way, without such express written permission, shall be removed at the expense of the person or entity causing or permitting such encroachments, upon the request of the persons operating, maintaining, or controlling the easement or right-of-way or the owner of the easement or right-of-way, in the event that any such encroachments unreasonably or materially interfere with the use and enjoyment of the easement or right-of-way. Nothing in this section shall in any way affect the exercise of the right of eminent domain for the public purposes set forth in section 7-701, Idaho Code.
