The notice shall specify the type of tier emergency restriction and the duration of the restriction. Upon receipt of notice that an emergency restriction is in effect, the city shall provide notice in accordance with this section to limit or suspend the use of water within the city for the sprinkling or irrigation of lawns and gardens or for any other special purpose(s) under this code.
(3) Emergency lawn and outdoor use restrictions. The city may further limit or suspend the use of water for the sprinkling or irrigation of lawns and gardens, car washing, or for any other outdoor use whenever it is determined that the public exigencies require such action.
