Michigan – China Clean Tech SymposiumTimothy J. Dekker, Ph.D., P.E.
Cities worldwide have interrelated issues of water sustainability and market opportunity• Environmental/water resource issues:– Watershed alteration and hydrology– Water quality impacts– Water supply limitations– Altered rivers: dams, levees, sediment dredging– Land development conflict with river
• Market Issues:– Development / regulatory interactions– Obstacles to value creation
Donlands Economics• 275 acres• $140M base development cost (+?)• Area to accommodate --------- annual tax revenue
– 25,000 population– 10,000 jobs $100M– 12M sf residential $25M– 16 M sf commercial $100M
• Increased property value• Increased economic activity• Parkland and waterfront – increased value as destination
Implications for China• Significant water resources issues in China
– Songhua River toxics spill– Lake Tai algal issues and drinking water source pollution– Jiaozhou Bay – algal blooms– Water supply – dams and interbasin transfers
• Past environmental and economic damage• Future development:
– Environmental regulations that focus on sustainability– Move from mitigation to planning – Development entities that make sustainable development
