About Us

The Hilo Downtown Improvement Association (DIA) is a 501 (c) 6 non-profit organization established in 1962 to preserve and revitalize Hilo’s historic district. The DIA serves as a collaborative, community voice that works to promote, support, and sustain the history, culture, environment, and economy of the area.

The DIA is contracted by the County of Hawaii Mass Transit Agency to manage the HILO INFORMATION CENTER located at the MOOHEAU BUS STATION, 329 Kamehameha Avenue. The DIA is funded by a combination of sources including membership dues, grants, donations, fund raising and through the Mass Transit contract.

In addition to managing the information center, the DIA is an active partner with county police, fire and civil defense to insure a safe and secure community, and county planning and public works agencies to avoid unnecessary building code and other restrictions.

Programs and current events of the DIA include:
“Revitalization: One Wall at a Time” mural project
