The University of Georgia has published a toolkit for coastal communities to assess their public service outreach abilities in times of flooding. This 71-page step by step guide will allow towns and cities along the coast determine their vulnerabilities to coastal flooding from hurricanes and rising sea level and determine what methods of outreach are already in place to notify residents of those areas. You can download a copy of it at https://cviog.uga.edu/_resources/documents/publications/community-rating-system-publication.pdf.
