Climate Change and Water Resources Planning

This document explores the impacts of climate change on water resources planning, focusing on rising seas, changing precipitation patterns, and increasing temperatures. It discusses vulnerabilities in flood control, water supply, and natural systems, offering adaptation strategies and recommendations for action. The paper highlights the importance of regional coordination and information sharing for effective planning and management.

Presentation Transcript

  1. Climate Change and Water Resources Planning Kim Shugar Department Director Intergovernmental Programs City of West Palm Beach 5/06/10

  2. Climate Change & Sea Level Rise • A global phenomenon • Impacts & actions are local • SFWMD’s primary focus is on regional water management issues and coordination with federal/state/local governments • Affected Mission Elements • Flood Control • Water Supply • Natural Systems • Water Quality • Climate Change Stressors • Rising Seas • Increasing Temperature • Changing Precipitation • Changing Tropical • Storms and Hurricanes

  3. SFWMD White Paper Conclusions • Current Climate Change Projections for SFWMD planning: • 5 to 20 inches of sea level rise by 2060; need regional information and coordination with other agencies

  4. Vulnerability & Adaptation

  5. Stormwater and Flood Control • Potential limitations on discharges • Future options: • Potential need for additional storage in basin • Potential need for additional on-site retention • for new development or re-development • Pumps

  6. Preliminary Assessment of Vulnerable Structures • Palm Beach County structures all have > 5.0 feet difference between headwater and tailwater • Need to evaluate secondary drainage system and locally permitted stormwater systems

  7. Area Surrounding S-27 Structure

  8. Rising Seas - Water Supply Impacts Saltwater Intrusion

  9. Water Supply • Evaluate opportunities and technologies to reduce additional saltwater intrusion (using reuse as a hydraulic barrier) • Implement water conservation measures • Develop water supply options • Develop appropriate treatment technologies

  10. Adaptation Planning Review state of the science Assess climate vulnerability Identify critical information gaps Consider & prioritize key issues of concern Explore potential adaptation strategies Identify opportunities & mechanisms to affect change Recommend action strategies (short, medium, long-term)

  11. Data and Modeling Needs (To be jointly developed by Federal/State/Local Agencies)
