From the Center for Disaster Philanthropy, this article on Long Term Recovery Groups. An excerpt:
The structure of an LTRG will vary depending upon impact of disasters, size of community, number of VOADs in the community, pre-existing strengths of community organizations, etc.; ideally, staff should be hired to run an LTRG or there here should be an organization dedicated to providing backbone support to help call meetings, form agendas, take minutes and enable communications. A fiscal sponsor is also needed to support fund development activities; this could be a community agency or a philanthropic partner.

Good article on a little known, but vital piece of the recovery process. As a FEMA Voluntary Agency Liaison for 15 of my twenty year career, I’ve watched amazing things happen when you put together the FEMA grant money, volunteers, donated materials and the knowledge needed. Millions of dollars, thousands of homes and tens of thousands of families have been assisted by LTRG over the last 20 years.
Thanks for sharing your experience.
