i Abstract This project provided the Greater Wellington Regional Council with community-input based recommendations for improving their current flood warning system on the Waiwhetu stream to promote a more people-based warning system. We achieved this by researching their current warning system, developing preparedness materials, and investigating the community’s perceptions of preparedness, awareness, and the current system. We recommended implementing tiered, redundant early warning media including Emergency Mobile Alerts and voice sirens, a flood preparedness campaign, and an all- stakeholder “one-stop shop” website. ii Executive Summary Introduction Natural disasters have killed nearly three million people in the last 20 years, and the United Nations predicts disasters will become more lethal (United Nations International Strategy for Disaster Reduction [UN/ISDR], 2015). Warning systems decrease risk from these disasters by allowing robust community action before disasters occur. These systems tie together strategies for early detection, communication, and public preparedness as community preference and the expected severity of disasters require. In the Lower Hutt region of New Zealand, the implementation of these strategies for flooding do not meet the standards necessitated by the severity of flooding in the region or the preferences of the community, requiring the Greater Wellington Regional Council (GWRC) to revamp their systems in an effort called the ‘Flood Warning Improvement Project.’ Our role within this project is to collect feedback from the community on communication preferences and public preparedness as a pilot program for the wider project. Background In the last 20 years, 4.4 billion people have been affected by disasters at the cost of US$4.8 trillion, mainly affecting lower- income communities without resources to protect themselves.
