Building in a floodplain is like pitching a tent on a highway when there are no cars coming.

Protect Property from Flood Damage

The most effective way to protect your property from flood damage is to choose a location outside of the floodplain that is not susceptible to flooding or drainage problems. But what about buildings and other development that are already located in high risk areas?

Floodproof Existing Buildings

Techniques for floodproofing (retrofitting) existing flood-prone development include:

  • Elevation of the building above the anticipated height of floodwaters.
  • Relocation to a new site outside of the floodplain.
  • Levees and floodwalls can be built around at-risk areas.
  • Dry floodproofing involves sealing building walls with waterproof compounds so that the structure is watertight.
  • A variety of wet floodproofing techniques allow the structure to flood, but reduce the resulting damage to the building and its contents.
  • Temporary barriers, such as sandbags, can be installed when flooding is anticipated.


Consult with your municipal building official for information and assistance with floodproofing techniques.

Floodproofing Information Sheets

STC developed a series of floodproofing information sheets with basic information about different floodproofing techniques and how to evaluate the options. FEMA also developed fact sheets about “Protecting Your Property from Flooding.”

Consider Purchasing Flood Insurance

Insurance doesn’t prevent flood damage, but it can be a valuable tool for protecting the financial investment in buildings and contents. Flood losses are not covered by most insurance policies.

Flood Insurance

Make informed decisions about whether you need flood insurance to protect your financial investment.

Flood Resilience Planning

Flood resilience and hazard mitigation planning are critical steps toward coordinated implementation of activities that will reduce future damages from events that we hope will never occur. The planning process enables a community to develop a program of activities that can be implemented now, before a disaster strikes. After evaluating the problems and considering potential solutions, the community identifies the most appropriate and efficient actions for reducing future damages.
