FEMA Mitigation Best Practices: When it Rains, it Pours: Blocking Rainwater and Preventing Sewer Backup   [open pdf - 30KB]

This document is part of the Federal Emergency Management Agency (FEMA) Best Practices Portfolio. The Best Practices Portfolio is a collection of true stories about people and communities who have experienced disasters, and what mitigation they used to survive, rebuild, and prepare for disasters. From the document: "With an abundance of buildings, streets and parking lots, urban areas have very little green space to absorb or slow down the onslaught of water in a heavy rain. It's especially a problem in the City of Chicago, a city built on a swamp. The high water table contributes to slower absorption rates and more water flowing overland to fill the city's sewers - an interconnected system carrying both storm runoff and sanitary sewer waste. A $7.8 million grant from the Federal Emergency Management Agency Hazard Mitigation Grant Program (HMGP) jumpstarted the Chicago project in 1998 by funding a pilot program in three areas of the city that were repetitively hit with basement flooding." This and other individual FEMA Best Practices documents are also combined in "Mitigation Best Practices: Public and Private Sector Best Practice Stories for All Activity/Project Types in All States and Territories Relating to All Hazards [August 10, 2011]," which can be accessed at the following link: [https://www.hsdl.org/?abstract&did=683132]
