Environmental Quality / Emergency Management
• Water Quality – Water Quantity Concerns
• Not usually grouped together in organizational framework
• Not always funded or managed together
• Consider: Organizational / Financial / Regulatory
• Temporal and Spatial – Flooding events big and fast
• Water Quality - big or small and fast or slow
• Mitigation, Response, Recovery and Preparedness
