Who We Are
Formed in 1986, the Astoria Downtown Historic District Association (ADHDA) is a non-profit organization whose mission is to preserve and advance historic downtown Astoria’s culture and character through inspired partnerships and community engagement to support a vibrant and resilient economic future for all Astorians.
ADHDA is a Nationally Accredited, Performing Main Street Community, as recognized by the National Main Street and Oregon Main Street Programs. With a dedicated 12-member board and 4 hard working committees, ADHDA implements the 4-Point Main Street Approach throughout the downtown district, which is primarily comprised of 38 blocks: from 5th to 17th Streets to the west and east and from Exchange Street to the Columbia River to the south and the north.
