Why moisture builds up in Springfield homes

Water nearby: James River, Galloway Creek and Jordan Creek, plus Lake Springfield and Fellows Lake nearby.

Flood history: Jordan Creek floodwater reached the second story of buildings on Boonville in 1859, a flood in 1909 was one of the worst, and floodwater reached 4 feet on Jefferson Avenue in 2016.

Setting: The city sits on the Springfield Plateau in the Ozarks. It is mostly flat, with rolling hills and cliffs to the south, east and north.

Missouri summers are hot and humid. NOAA's 1991-2020 normals put average yearly precipitation at Springfield 44.7 inches, Poplar Bluff 50.8 inches. Warm, damp air is what lets mold take hold in attics, crawlspaces and bathrooms.

Housing age and hidden moisture in Springfield

Housing: The Walnut Street Historic District grew from about 1870 to 1940, with 21 surviving buildings from before 1900 and 59 from 1901 to 1910.

Questions

Common questions.

Why did Springfield bury part of Jordan Creek?

Floods hit the downtown creek every few years. It was moved into a box culvert between Boonville and Main in the late 1920s.

Where does the name Springfield come from?

The origin is unclear. One 1883 account credits a spring under the hill, but an 1881 editor disputed that.

Why is mold common in southern Missouri homes?

Southern Missouri has humid summers and about 45 to 50 inches of precipitation a year, based on NOAA normals for Springfield and West Plains. EPA advises keeping indoor humidity below 60 percent, ideally 30 to 50 percent. Basements, crawlspaces and bathrooms are where moisture tends to collect.

Why do crawlspaces and basements matter in Missouri houses?

EPA notes that crawl spaces with high humidity are common sites of hidden mold growth, especially over bare soil. Missouri summers are humid, so foundation moisture is a frequent buyer concern. EPA also advises grading the ground away from the foundation so it does not stay wet.
