     (b) Consult with the local mosquito control district, where established, in the development of construction plans that include storm water retention ponds; and
     (c) Provide for maintenance and control of vegetation growth in storm water retention ponds to reduce mosquito habitat and inhibit mosquito propagation without compromising the intended function of a storm water retention pond.
     (2) A county, city, town, water-sewer district, or flood control zone district operating or maintaining storm water control facilities must, except where mosquito control districts are established, when notified by the department of health or a local health jurisdiction of the positive identification of west nile virus or other mosquito-borne human disease viruses in mosquitoes, birds, or mammals, including humans, consult with the department of health or a mosquito control district concerning which integrated pest management strategies, as defined under chapter 17.15 RCW, for mosquito control or abatement in storm water retention ponds would be most effective to prevent the spread of the disease.
     (3) Where a mosquito control district is established, when notified by the department of health or a local health jurisdiction of the positive identification of west nile virus or other mosquito-borne human disease viruses in mosquitoes, birds, or mammals, including humans, the mosquito control district is responsible for mosquito control or abatement in storm water retention ponds."
