Floodplain Compliance
CSU reduces flood risk through updated planning, flood mitigation projects, and review of construction that occurs in or near the floodplain.
100-Year Floodplain Map
This map shows modeled 100-year floodplain conditions for Colorado State University, including floodplain boundaries, shallow flooding areas, major basin boundaries, inflow and outflow locations, water surface elevations, and flow rates.
The map is provided as a visual reference. Users who need assistance interpreting the floodplain map or who need the information in another format should contact Facilities Management.
What Floodplain Compliance Supports
Since the 1997 flood event, CSU has continued improving floodplain management, stormwater infrastructure, and campus resiliency efforts. Floodplain reviews help guide campus projects and support safer long-term development decisions throughout the university.
Flood Mitigation
CSU coordinates flood mitigation efforts to reduce risk to buildings, utilities, infrastructure, and surrounding waterways.
Construction Review
Projects near floodplain areas are reviewed to ensure compliance with FEMA and local floodplain requirements.
Campus Planning
Floodplain data supports long-term campus development, resiliency planning, and environmental stewardship.
How CSU Reduces Flood Risk
Infrastructure Improvements
Stormwater systems, detention areas, and drainage improvements help reduce flood impacts across campus.
Planning Coordination
CSU integrates floodplain review into project planning and campus development decisions.
Regulatory Compliance
Floodplain compliance efforts align with FEMA requirements and local floodplain regulations.
Does Your Project Impact the Floodplain?
