Brooklyn Township and the potato years.
The first white settlers arrived in 1852, after the federal government opened the territory. Washington Getchell and his son Winslow staked claim to what is still called Getchell Prairie in the southern part of the township. Ezra Hanscom, from Maine, built nearby. By 1853 the area had been named Brooklyn Township after the settlers' previous home in Brooklyn, Michigan. On May 11, 1858 — the same day Minnesota became a state — the first town meeting was held at Hanscom's house and the first township officers were elected.
For the next ninety years almost nothing changed. Brooklyn was farm country. Potatoes especially — the crop did so well in the local soil that the annual Tator Daze festival still survives as a civic ritual. The 1950 census put the township at 1,694 people. That is one of the smallest populations of any city WPNE services. Brooklyn was still, by every honest measure, a small agricultural village ninety-eight years after it was named.
The Mississippi River boundary.
Brooklyn Park's eastern boundary is the Mississippi River. Across the water sit Coon Rapids and Fridleyin Anoka County. That river is more than a property line — it's a geological border. Brooklyn Park is on the Hennepin County side of the channel, where the surficial geology is dominated by glacial till deposits left by the retreating Wisconsin glacier. The other bank, across the water, is the start of the Anoka Sand Plain.
That matters because the cities feel similar but their basements behave very differently. The same rambler built in 1958 will fail in different ways on each side of the river. Brooklyn Park homes are far more often dealing with clay-content till and the “clay bowl” effect against the foundation. Across the river, those same homes are dealing with sand transmitting water fast and shallow water tables. We work both sides regularly, and the right answer is rarely the same.
Glacial till and what it does to basements.
Glacial till is the unsorted mix of clay, silt, sand, and gravel that an advancing ice sheet bulldozes ahead of itself and dumps when the ice retreats. Most of Brooklyn Park sits on it. Till is structurally fine for building on, but it's difficult for water management because it's neither one thing nor the other — the clay content holds water against the foundation, and the embedded sand and gravel pockets transmit water in unpredictable directions.
The clay bowl effectis the most relevant failure mode here. When a basement was excavated and the foundation poured or stacked, the contractor backfilled with the looser material from the dig. That loose backfill is more permeable than the undisturbed clay-rich till around it. Water entering the loose backfill — from rain, snowmelt, a leaking downspout — has nowhere to drain through the surrounding dense till, so it sits in the trench around the foundation and pressurizes the wall. In Brooklyn Park, almost every basement we've diagnosed has some version of this happening.
From 1,694 to 20,640 in twenty years.
The first housing developments appeared in the 1940s in the southern part of town. After that, the curve bent steeply. Population: 1,694 in 1950, then 20,640 by 1970. The Township incorporated as the Village of Brooklyn Park in 1954 to handle the growth. In 1969 it became a city. Across those two decades, the southern half of Brooklyn Park filled in with the same product Bloomington and Blaine got — small ramblers and minimal-traditional starter homes, mostly on cinder block foundations, mostly with single perimeter drain tile and thin tar dampproofing.
Those 1950s and 1960s homes are now sixty to seventy years into a useful life that was designed assuming twenty. They are the densest concentration of our service calls in the city.
The poured-concrete buildout.
Brooklyn Park kept growing well past its first boom. The northern half of the city — beyond Highway 610 and into the area that had still been farmland in the 1980s — filled in with poured-concrete homes through the 1980s, 1990s, and 2000s. Today the city has around 80,000 residents, making it the sixth-largest city in Minnesota and a city built from two different construction eras living next to each other.
The poured-concrete walls are structurally superior to the cinder block of the 1950s blocks — monolithic, no mortar joints, no hollow cells. The dirt underneath them is the same glacial till, and the surface water plan still depends on grading, downspouts, and a working sump. When those go out of tune, the wall is fine and the basement still gets wet.
Why Brooklyn Park basements leak today.
A Brooklyn Park leak is almost always one of two stories:
- The 1950s–60s cinder block rambler in the southern half. Wall has hundreds of mortar joints. Original drain tile has silted up. Grading has been re-graded by every owner since the original sod. Clay bowl effect pressurizes every spring.
- The 1980s–2000s poured-concrete home in the northern half. Wall is fine. Surface drainage has fallen out of tune over twenty or thirty years. Downspouts now drop water at the foundation. Drain tile has silted. Cove joint cracks open under hydrostatic pressure.
What this means for your home.
The 1950s and 1960s blocks south of 85th are at the point in their lifecycle where the original drainage system is fully expended. For most of those homes, an interior drain tile system with a modern sump is the honest answer. We'll quote that work directly and back it with a lifetime transferable warranty.
Newer homes in the northern half are a different conversation. The high-leverage opening move is usually a sump replacement, a downspout and grading correction, and a flush of the existing tile. Those are obvious contributors worth investigating first — addressing them often keeps the basement dry for another fifteen or twenty years and, depending on what you want from the space, can save thousands. We'll walk through what we see and lay out the options. That's the job.
