Floodplain Regulations

In general, the City's Floodplain Regulations (PDF 14.2MB) are stricter for new structures and residential buildings than for existing structures and commercial buildings. Contact Utilities before undertaking any construction (new development, additions, remodels, filling, grading, etc.) on a building or property located in a regulatory floodplain to determine specific flooplain requirements.

Different floodplains have different regulations. A floodplain use permit is required for all construction in the floodplain.

The regulations are designed to:

• protect the health and safety of citizens;
• minimize property damage when a flood occurs; and
• ensure new development does not make flooding problem worse.

Two guides help explain portions of the regulations:

• Poudre River Quick Guide (PDF 1.5MB)
• Quick Guide (PDF 1.7MB)
