This report was produced in partnership with the Association of State Floodplain Managers, with funding from FEMA, which makes it available for free to all.
A lot has changed since APA released its first PAS Report on Subdivision Design and Flood Hazard Areas in 1997. Today sustainability, resilience, and climate change are top of mind for planners and floodplain managers.
But for subdivision design, those ideas haven’t yet hit home. The results? Untold damage from Hurricanes Sandy and Katrina as well as floods in places like Colorado and Atlanta.
This updated report is out to end the cycle of build-damage-rebuild. Editor James C. Schwab, FAICP, manager of APA’s Hazards Planning Center, gives communities sound guidance to bring subdivision design into line with the best of floodplain planning.
Six planning and design principles help put subdivisions on the right footing. Standards for review, inspection, and maintenance cover all types of terrain and infrastructure. And nine concrete recommendations lay out steps to keep subdivisions safe and dry. Readers will get the tools they need to save lives, protect property, and build a better future.
