  • Carol & Pete’s slides
  • Background, NL - US
  • My first project, design and engineering of Wadi in 1998 in Dutch countryside including “community outreach”. GI did not exist those days, but common sense did
  • 1. Netherlands in 1stcenture, unlivable, mud, water, fully exposed … farmers starting to organize in 800, waterboards start, collective responsibility, start shaping the landscape, integrating water questions in settlments, polders and terpen, first “urban areas” ---- more images / extra slide (rural development, water management 18th century)2. What if statistics proof right, sealevel goes up and rivers reach peak levels – are we going back to 1st century? How do we manage. 2 examples, city of Zutphen and City of Rotterdam. ADD animation
