The council shall determine how adequate moisture is to be measured under this subsection. Landscape irrigation systems do not include irrigation systems installed for the commercial production of agricultural crops nor irrigation systems installed for agricultural or silvicultural research plots of state institutions of higher education.
NEW SECTION. Sec. 2. This act is necessary for the immediate preservation of the public peace, health, or safety, or support of the state government and its existing public institutions, and takes effect immediately.
