About the Preservation Ordinance
Rock Island City Council adopted the Rock Island Preservation Ordinance in 1984 and amended it in 1986. The ordinance established the Rock Island Preservation Commission
and the procedure by which to designate buildings and areas as Rock Island Landmarks or Historic Districts. It also set in place a review process in which landmark owners need a Certificate of Appropriateness
to alter the exterior of the landmark building or site. This process ensures that landmark properties maintain the integrity that enabled them to achieve designation.
