Sixty percent of every house here was built in nine years.

The Minneapolis & St. Louis Railway and the 1886 Village.

The name “St. Louis Park” comes from the Minneapolis and St. Louis Railwaythat ran through the area; the “Park” was added to avoid confusion with St. Louis, Missouri. In August 1886, 31 people signed a petition asking the county commissioners to incorporate the Village of St. Louis Park. The petition was registered on November 19, 1886. At incorporation the village was a handful of separate neighborhoods, not a cohesive community — a scattering of small settlements around the railway tracks and the area's lakes.

Thomas Barlow Walker and industrial St. Louis Park.

In 1892, lumber baron Thomas Barlow Walker and a group of wealthy Minneapolis industrialists incorporated the Minneapolis Land and Investment Companywith the express purpose of concentrating industrial development in the village. Walker's company began developing St. Louis Park for industrial, commercial, and residential use, with development radiating outward from the original village center at the intersection of the M&StL Railway and Wooddale Avenue.

The Moline Plow Company era.

By 1893, downtown St. Louis Park — then along Broadway, which is now Walker Street, near Lake Street — had three hotels and several fraternal meeting halls. Around 1890, the village had more than 600 industrial jobs, mostly tied to the massive Moline Plow Company factory just south of downtown. That made St. Louis Park an industrial worker town. The houses that went up to house those workers were small bungalows, four-squares, and craftsman homes on fieldstone, brick, and early concrete block foundations. Many of them still survive in the older blocks near the railroad corridor.

Bass Lake and Hennepin County till.

St. Louis Park sits on glacial till — the mix of clay, silt, sand, and gravel left by the retreating Wisconsin glacier. The clay content holds water against foundations, and the embedded sand and gravel pockets transmit it unpredictably. The clay-bowl effect is the most common failure mode here.

Bass Lake, which in the 19th century covered roughly 80 acres reaching as far north as Minnetonka Boulevard, was one of several lakes and wetlands that defined the original landscape. Much of that wetland area has been filled or drained over the past 120 years, but the high water table beneath those filled lots is still there. Properties on or near the historic wetland margins are some of the most challenging basements we work on in St. Louis Park.

1,122 building permits in 1950.

The post-war boom hit St. Louis Park harder than almost any other Minnesota suburb. In 1950 alone, the village issued 1,122 building permits — the third-most of any municipality in the state, behind only Minneapolis and Saint Paul. Between 1950 and 1956, 66 new subdivisions were recorded and 2,700 new homes were built. Sixty percent of St. Louis Park's homes were built between 1946 and 1954.

Major post-war builders here included Adolph Fine (an estimated 2,000 homes), Ecklund & Swedlund (3,500+ projects), Bruce Construction, S&H Construction, Westwood Hills Construction, and Sam Segal. The product was almost universally the same: small ramblers and minimal-traditional starter homes on cinder block foundations, priced for veterans on $25-a-month payments under VA-spec construction standards. Drain tile was a single perforated pipe at the footing. Exterior dampproofing was a thin tar coat. Grading was whatever the bulldozer left.

That is the housing stock under most of St. Louis Park today.

Why St. Louis Park basements leak today.

A St. Louis Park leak is almost always one of three stories:

1. The 1900s–1930s worker bungalow. Stone or early-block foundation. Mortar crumbling. Century of freeze-thaw. Modern finished basements have made the moisture problem worse.
2. The 1946–1954 cinder-block rambler. By a wide margin the most common. Wall has hundreds of failing mortar joints. Drain tile silted. Grading shifted. Clay-bowl pressurization every spring.
3. The lakeshore or filled-wetland property. Whatever the foundation is, the water table sits at slab elevation in spring. Hydrostatic pressure at the cove joint is the typical failure mode.

What this means for your home.

If you live in a 1950s St. Louis Park rambler — and most homeowners here do — the honest answer is usually a full interior drain tile system with a modern sump and proper vapor management. The original 1950s drainage has run out its useful life. The wall has run out its mortar. The yard has been re-graded by every owner since the original sod. We'll quote that work directly and back it with our lifetime transferable warranty.

For the rare St. Louis Park home that isn't a 1950s rambler — older bungalows near the rail corridor, or the small slice of newer infill — we look first at the surface water plan. Often the high-leverage opening move is a sump replacement, a downspout and grading correction, and a flush of the existing tile. Those are obvious contributors worth investigating first — addressing them, depending on your goals for the space, can save thousands and extend the time before a full system is necessary. We'll tell you which.
