This handbook documents Catholic Relief Service's experience in planning and implementing its urban transitional shelter response in Port-au-Prince, Haiti. The handbook highlights challenges, successes and key aspects that could be useful in future responses to urban disasters. This publication is a result of site visits, studies of internal and external documentation and interviews with beneficiaries and community members during the 2010“2012 post-earthquake period. CRS is currently planning for permanent reconstruction programs in Haiti and is scheduled to pilot such a program in May 2012.
