Local Health Boards.
Local boards of health (boards) are county-level organizations with a wide remit over matters of public health. Boards enforce state public health statutes and rules through a local health officer, control and prevent infectious diseases, and prevent, control, or abate public health nuisances.
The board membership requirements for home rule charter and noncharter counties are similar in that each is comprised of three parts. First, the board must include county commissioners or representatives from the county legislative authority. Second, members who are not elected officials must be selected who represent:
Third, the board must include a tribal representative selected by the American Indian Health Commission if a federally recognized Indian tribe holds reservation, trust lands, or usual and accustomed areas within the county, or a charitable organization registered in Washington serves American Indian or Alaska Native people and provides services within the county.
The legislative authority or board of county commissioners may, in its discretion, increase by ordinance the size and composition of a board to include additional members, including elected officials from cities and towns, as long as the number of members from the three categories above is equal to the number of elected officials on the board.
District Health Boards.
Each county has a board that is coextensive with the county, unless the county has opted to create a health district (district) on its own or in conjunction with one or more other counties. A single-county or multi-county district board of health operates in a similar manner and has a similar governing and membership structure to a local board of health.
Modifications are made to tribal representative membership on district and local boards of health (Board). A Board must allow a tribal representative from each of the following, and notify the American Indian Health Commission:
The tribal representative must be selected by the tribe or organization. If a tribal representative is added to a Board as provided above, the county commissioners or county legislative authority must modify the membership of the Board to comply with applicable Board membership requirements:
The State Board of Health must adopt rules establishing timelines for modifying the membership of a Board as required by state statute. The rules must go into effect no later than 1 year after the effective date of the bill.
