The City and County of Honolulu’s Resilience Strategy is forthcoming in 2019. As part of the Rockefeller Foundation’s 100 Resilient Cities process, over a period of seven months, Honolulu’s resilience team conducted an intensive public engagement and fact finding effort, during which we engaged some 219 organizations across the island, all 33 neighborhood boards. Throughout this engagement process we conducted an 11 question survey via three formats:  live, interactive polling; hard copy paper surveys, and an on-line survey tool. In total the Resilience Officer received survey input from more than 2,200 individuals representing the range of Honolulu’s geographical, ethnic, gender, and age diversity. This initial research concluded in March, 2018. The results of this survey are captured in the City’s Preliminary Resilience Assessment, and will be published in Honolulu’s Resilience Strategy.
