New Stormwater Improvements Protect Harry S. Truman Farm Home

The historic farm home of Harry S. Truman had significant foundation issues, including water infiltration and settlement/movement. The National Park Service needed to remove and replace the majority of it, while preserving the site. This posed a unique design challenge.

STRATA Architecture + Preservation was selected to lead the effort. They chose our firm to provide the civil engineering and survey services. To begin, we conducted a topographic survey. Our engineers also walked the site, making recommendations on changes that could improve drainage and protect the foundation.

One of our primary objectives was to keep water away from the foundation. This was addressed in two ways. First, where foundation repairs took place, the new surface elevation was graded to provide positive drainage away from the building. Second, as part of the foundation repairs, granular backfill and perforated pipe was installed to help collect and remove groundwater adjacent to the foundation. This water was then piped underground to an outfall away from the building.

Preserving the site and its historical significance was a top priority for the National Park Service. Existing plants adjacent to the house were removed before any foundation work began. These plants were relocated to a designated storage area on site for protection. Upon completion of construction, they will be returned to their original locations.

Currently under construction, the completed improvements will help protect a piece of American history. By thinking outside of the box, we were able to protect the home’s foundations and preserve its unique characteristics. Striking this balance means residents and visitors can enjoy this landmark for years to come.
