Local risk profile
About 35,815 people live in Geary County, 385 square miles in northeast Kansas, in roughly 15,939 homes. Junction City is the county seat; Grandview Plaza and Milford are the next largest communities. Much of its housing is recent, with a median build year of 1987.
41/100 Water Damage Risk Index: Moderate Geary County ranks 85 of 105 Kansas counties. See the statewide ranking and method.The three factors where Geary County ranks highest compared with other Kansas counties.
Pipe-freeze risk in Geary County sits near the middle of the state. In the 2015–2024 record the county logged about 35 nights a year at or below 20°F (63rd of 105) and 108 below freezing. Twenty degrees is roughly where uninsulated pipes start to freeze.
The longest cold spell was straight 13 days without the temperature rising above freezing, ending in February 2021. The coldest night reached about -18°F on February 16, 2021. Burst pipes usually show up when a spell like that breaks and the ice thaws.
Most freezing nights fall from November to February, peaking in January. Disconnect garden hoses and shut off outdoor spigots before the first hard frost, and keep the heat at 55°F or higher if you'll be away.
Freezing nights typically start around Oct 26 and end around Apr 9.
Heavy rain is a bigger factor here than in most of Kansas. The county gets about 33.7 inches of rain and melted snow a year, with 8.9 days of an inch or more (28th of 105). Those downpours cluster in May, June and July, when sump pumps and gutters are tested hardest. The wettest day on record brought 2.55 inches on June 23, 2019. The worst three-day stretch dropped 4.2 inches, ending May 9, 2019, the kind of soaking that overwhelms sump pumps and storm sewers.
Freeze-thaw days, below freezing overnight and above it by afternoon, come about 89 times a year here. They're the main driver of ice dams and of water working its way through foundation cracks in late winter.
Housing
42% of homes in Geary County predate 1980, below the Kansas county median of 73.7%, which ranks 103rd of Kansas's 105 counties.
Growth since 2000 added 40% of today's homes. In houses that new, the weak points are washing machine hoses, ice maker lines, water heaters and sump pumps rather than the pipes in the walls.
Renters occupy 57% of homes. If you rent, the building is usually the landlord's to repair, but your belongings are only covered by renters insurance.
Beyond water
Geary County averages 70 warm, muggy nights a year (lows of 65°F or more) and gets the most rain in May. Keep indoor humidity under 60%, as the EPA advises, and dry any leak within 24 to 48 hours; in a humid month a wet basement left alone won't dry by itself.
Mold remediation: what to expectHeating fuel matters for fire risk. In Geary County it's 50% utility gas, 41% electric, 6% propane and under 1% wood. Heating equipment, cooking and electrical failures cause most home fires nationally. Even a small kitchen fire can leave soot through the whole house, because smoke follows air currents into closets, ducts and attic space.
