This document summarizes David Waggoner's work on integrated resilience projects in New Orleans. It discusses New Orleans' coastal conditions, high-low landscape, impacts from Hurricane Katrina, and international case studies from places like Jakarta and Japan that informed New Orleans projects. It then outlines Waggoner's proposals for New Orleans including developing living lines of defense, interceptor streets, and improving drainage systems through strategies like detention, retention, and slowing water flows. The proposals aim to reduce flooding and subsidence risks while creating economic and environmental benefits.

At the core of our project is a three-part
collaboration between teachers, design experts
and water experts.
- Teachers contribute knowledge of curriculum
design and implementation.
- Design professionals and educators
contribute knowledge of visual, hands-on,
and experiential learning.
- Water experts contribute content expertise in
international and local water issues.
