Greater Des Moines Habitat for Humanity is hosting a weeklong AmeriCorps Build-a-Thon this week. The May 19-23 event will bring 150 AmeriCorps workers and alumni to Des Moines. The local Habitat for Humanity was chosen to host the event as part of a national competition. Its team will work alongside Build-a-Thon participants to start building two new Habitat homes, as well as renovate a third. The team also will complete repair and maintenance projects on 17 existing homes and several community projects through Habitat's neighborhood revitalization program.
