2025 Spring Flood Update  for levee elevations and historical flood levels.

South St. Paul Riverfront

South St. Paul is situated along the Mississippi River, which rises and recedes regularly based on rainfall, snowfall, and the rate of spring snowmelt. Due to the potential for flooding of properties adjacent to the river, a permanent levee or flood wall was constructed:

Property Protection Flood Walls

• Properties near the river from approximately I-494 to just north of Wentworth Avenue are protected by a permanent levee or flood wall with an average elevation of 710.0. See Map of Levee Protected Area.
• Properties near the river and north of Wentworth Avenue are not protected by the permanent levee. The contours vary in height. See Map of Area North of Levee.
• Properties near the river and south of I-494 are not protected by the permanent levee. The contours vary in height. See Map of Area South of Levee.

Protective Measures

If the City anticipates flooding, properties east of Concord Street should prepare for possible flooding. Protective measures include:

• Move valuable items to a higher elevation or alternate location.
• Move hazardous items to a higher elevation or alternate location.
• Prepare for evacuation.
• Secure or disconnect electrical service (contact Xcel Energy for guidance).
• Sign up for emergency notifications through the Everbridge System:
  • Landline numbers are automatically notified.
  • Wireless numbers must be registered.
• For flood preparation resources, visit North Dakota State University’s flood preparation publications.

Sandbagging for Flood Protection

• A sandbag dike must be built properly to prevent or reduce flood damage.  The NDSU website provides guidance on constructing a sandbag dike.
