Polk City, IA lies about 14 miles north-northwest of downtown Des Moines, along Saylorville Lake and near Big Creek State Park. It is its own city in Polk County, with its own public works and permits. The 2025 Census estimate counts 6,630 residents, about 20% more than in 2020 and nearly double the 3,418 of 2010.
Newer Basements in Polk City, IA
Polk City, IA was settled in 1846 and incorporated on March 13, 1875. It took the name of President James K. Polk and once vied to become the county seat before Des Moines was picked. It keeps Polk County's only "town square"; its motto is "A City For All Seasons."
Census survey data place the typical home at about 2004; only about 7% predate 1960, and more than a third went up since 2010. Of 2,231 homes, about 79% are detached and about 89% owner-occupied. The $414,800 median value tops the five towns here.
Many were built with drain tile, a sump and, often, poured walls. That isn't watertight: tile silts up, pumps wear out and backfill settles. This page is for homes that have a basement, which not all do.

How Each Service Fits Polk City, IA
- Capacity and backup. After July's rains, owners often ask about a second pump, battery backup and an alarm; see sump pump installation.
- Backfill that sank. Settled soil can slope a yard toward the walls; see basement drainage.
- Window wells. A well with no working drain can fill and leak at the frame.
- Shrinkage cracks. Thin cracks in young poured walls usually take injection; see foundation crack repair.
Nine-Plus Inches and the Lake Next Door
The storm came in two waves over July 2 to 4, 2026; the National Weather Service called 5-to-10-inch totals common across the county's north. Preliminary reports from Polk City, IA showed more than 9 inches in 24 hours. On July 20 the metro took 4 to 6 inches more. No count of wet basements exists.
Saylorville Lake is a federal reservoir that holds back the Des Moines River upstream. Much of the metro sits on dense Des Moines Lobe till, and soils formed in it can stay wet a few feet down through spring.

One Office for Polk City, IA Sewers and Permits
The City's Public Works crew maintains the sanitary and storm sewers: 65 miles of sanitary sewer main and two lift stations, alongside 54 miles of water main. For a wastewater emergency, such as water rising from a floor drain, the City says to contact City Hall at 515-984-6233, which can also say which part of the line is yours.
The same number reaches Community Development, City Hall, 200 S. 4th St., whose permits cover "new construction, remodels, additions, alterations, repairs," with separate trade permits for plumbing, mechanical and electrical work, and the City's FAQ adds: "Building permits are required for all new construction projects and renovations." A drain-and-sump job may or may not count, so ask that office; any sewer tie-in needs a state-licensed plumber, and the contractor confirms the permits.

One Request for Polk City, IA Homes
One form replaces tracking down firms one by one. The site does no waterproofing or plumbing, is no contractor and sells no home improvements, and holds neither an Iowa contractor registration nor an Iowa plumbing license. Whoever receives the request may pay a flat fee to advertise, waived during a current trial; homeowners pay nothing and receive nothing.
- Itemize before signing. The contract should list work, materials, price and payments tied to progress, never everything up front.
- Plumbing goes to a plumber. A backwater valve or a pump tied into any drain needs a state-licensed plumber and a plumbing permit.
- Check the registration. Iowa licenses no waterproofers, but construction businesses above $2,000 a year file with the state; search DIAL's public portal yourself.

Quick Answers for Polk City, IA
Our house is barely ten years old. Why is there water downstairs?
Young basements have weak points too. A sump pump can quit or fall behind in a heavy rain, drain tile can clog with silt, and settling backfill can tip the yard toward the walls. A visit can narrow it down.
Does living near Saylorville Lake affect my basement?
The lake controls the Des Moines River, so its job is river flooding. It doesn't stop spring seepage through a wall or a backup through a floor drain. For a single house, the yard's slope, the drain tile and the pump matter far more.
What should I look at on my sump pump after July 2026?
Pour a bucket of water into the pit; the pump should empty it. Check that the discharge line runs outdoors, well away from the foundation. Ask about an alarm or battery backup, and a licensed electrician about any new circuit.
What if the water rose through a floor drain instead?
That suggests a sewer problem rather than seepage, and waterproofing won't cure it. The City says to contact City Hall at 515-984-6233 for wastewater emergencies. A state-licensed plumber can say whether a backwater valve fits your house; it needs a plumbing permit.
