ONE ECOSYSTEM INTEGRATION The city will use floating foundations and porous sea walls that mimic the tangled root systems of Mangrove forests. These structures break wave energy and prevent erosion during coastal flooding. TWO CIRCULAR FLOW Implement a Greywater Cascade system where household water is filtered through artificial wetlands before being reused for urban farming. This meets the Net-Zero 2026 design standard. THREE IMPACT METRIC Carbon footprint reduction $C = \frac{500 - 150}{500} \times 100 = 70\%$. FOUR IMPLEMENTATION PHASES 1 Construct the bio-shield sea walls within 3 years. 2 Install the decentralized wetland filters by year 6. 3 Complete the 100 percent water recycle loop by year 10.
