Adams County Board of Health Members Appointed

On Tuesday, Aug. 16, the Adams County Board of Commissioners (BoCC) approved resolutions appointing five inaugural members to the new Adams County Board of Health (BOH). The BOH is structured with five members. Initial terms are two- and three-year appointments for purposes of establishing staggered terms going forward. After the initial term, BOH members will serve five-year terms.

The BOH will hold its first meeting in late August to begin planning for the new Adams County Health Department (ACHD), and they will hit the ground running. Next steps for the BOH include hiring an executive director, appointing officers, and creating bylaws as progress continues toward standing up the county’s first public health department on Jan. 1, 2023.

“With this morning’s action approving these resolutions, we have completed a critical step in setting up the new health department,” said Lynn Baca, Chair of the Adams County Board of Commissioners. “While we had many qualified applicants, we believe this five-member board brings the varied expertise and perspective that is representative of our diverse county.”

Board of Health Basics:

  • State law requires the BoCC to appoint BOH members for the county. 
  • The BOH will be the governing body of the department and is the entity under which the entire agency will be formed and operate.
  • Many BOH responsibilities are set by state law and include: 
    • Developing and promoting public policies to support a healthy community
    • Approving the local public health plan completed by the agency
    • Selecting, supervising, and advising the agency’s executive director and medical officer
    • Issuing orders and adopting rules necessary to carry out public health duties
    • Fee setting
  • Once formed, the BOH will decide how they will operate their board through the creation of board bylaws, the appointment of board officers, and the creation of policies and procedures for board and agency operations.  
  • Boards of health can play many different roles based on the needs of the agency and the communities they serve. Adams County’s BOH will be informed by local assessments and plans, national guidance, and agency staff as it considers how best to support public health.
