New Technical Preservation Services Websites

October 25, 2022

Technical Preservation Services is pleased to announce the launch of our new websites.

The National Park Service web presence ( is presented through a content management system that provides a consistent appearance and features across all park, program, and office websites. The TPS web content has now been moved to the content management system and into two new websites,

There are several navigation aids throughout each site; the photo grid on the home page echoes the items in the black navigation bar, and the system automatically generates a site index of first- and second-level pages at the bottom of every page. Preservation by Topic has been updated to help you find information.

Compare the first- and second-level navigation of the old and new websites.

You will notice two changes in the websites' content. The first is that the information formerly found under "The Standards" tab has been split between the two new sites. The Secretary of the Interior’s Standards for the Treatment of Historic Properties with Guidelines for Preserving, Rehabilitating, Restoring & Reconstructing Historic Buildings are located in the Technical Preservation Services site. The Secretary of the Interior's Standards for Rehabilitation (regulatory for the tax incentives program) are located in the Historic Preservation Tax Incentives site, along with the guidance on applying the Standards that has been developed in the context of the tax incentives program.

The second change is that the Preservation Briefs are presented only as pdfs while we evaluate how to present them online.

All pages in the old website are permanently redirected to the home page of Technical Preservation Services, and bookmarks to pages on the old site will go to this page until updated.

Flood Adaptation Guidelines Now Available in Print

October 3, 2022

Technical Preservation Services is pleased to announce that the Guidelines on Flood Adaptation for Rehabilitating Historic Buildings are now available in printed format. Copies of the printed publication can be purchased from the U.S. Government Bookstore. Alternatively, you can go to the GPO Bookstore and enter the search term “flood.”

The Guidelines on Flood Adaptation are designed to provide information on adapting historic buildings to be more resilient to flooding in a manner that will preserve their historic character and meet The Secretary of the Interior’s Standards for Rehabilitation. These Guidelines outline adaptation methods that lower the flood risk of a property. The goal of this document is to achieve greater resilience while minimizing the impacts to the historic character of a building. The Guidelines provide information concerning professional flood adaptation methods and techniques along with preservation considerations and strategies for successfully planning such a project.

This publication was developed with support from subject matter experts representing Federal Preservation Officers, State Historic Preservation Offices, Tribal Historic Preservation Offices, Certified Local Governments, and non-profit preservation organizations.

The Guidelines on Flood Adaptation for Rehabilitating Historic Buildings are also available online along with frequently asked questions and a recorded introductory webinar.

Updated March 29, 2022

The Technical Preservation Services (TPS) office continues to be open and operating normally. Following an extended period of operating largely remotely in response to Covid-19, TPS staff are now generally working on a hybrid basis with both in-office and telework days.
