The goal of the Guidelines on Flood Adaptation for Rehabilitating Historic Buildings is to provide information about how to adapt historic buildings to be more resilient to flooding risk in a manner that will preserve their historic character and that will meet The Secretary of the Interior’s Standards for Rehabilitation. These guidelines should be used in conjunction with the Guidelines for Rehabilitating Historic Buildings that are part of The Secretary of the Interior’s Standards for the Treatment of Historic Properties with Guidelines for Preserving, Rehabilitating, Restoring & Reconstructing Historic Buildings. Like the Guidelines for Rehabilitating Historic Buildings , these guidelines are intended to focus primarily on historic buildings and their site and setting.
The treatments described in the Guidelines may be considered as means for preserving historic properties located in floodplains and making them more resilient to flooding hazards. While many of these treatments can be undertaken with minimal effects on the historic character of a property, some may require more change than would normally be acceptable in other contexts. Consequently, only buildings with a demonstrable risk of flooding should be using the adaptive treatments described in the Guidelines. Adaptation treatments should reduce the risk of flood damage as much as possible, but should do so without destroying significant historic materials, features, or spaces.
