The three principles of attenuation* protection, and planning are central to the design approach and methodology that define the Structures of Coastal Resilience project.
The implications for flood resistant design are
clear and can be surimarized in three
principles :
Attenuation and d issipation of wave
energy offshore to reduce the demands on
barriers and evees or wetlands where they
exist or to building and structures where they
do not;
Protection with both flood structures and
bui ld ing code requirements knowing that
some flooding w ill inevitably occur;
Planning for controlled flooding through
urban and landscape flood plain
management and design.

COASTAL CITY• (although it is 60 miles inland from the Atlantic Ocean)
• it sits within the Delaware Estuary
• it faces significant challenges from climate change
• the next 30 years: 10x tidal flooding events increase (19/yr to 200/yr)
Waterfront Development in a Changing Climate“Philadelphia is a Coastal City”, Tantala, 2017.06.20
• New Normals past designs were based on past climate conditions
• Changing Extremes more frequent and severe
snowiest winter, warmest summer, wettest day since 2010
• Rising Seas sea level rise raises levels in the Delaware & Schuylkill Rivers
increases depths and extent of flooding (storm surge)
sea level rise 0.11 in / yr since 1900, one foot in 100 years!
