Class 5 is the base gravel most of this county is built on, and it is the material to know first. Around the Devils Lake Basin, ground that holds water makes what goes under a drive matter as much as the gravel on top.

Ground Conditions Across Benson County

The working season here runs from the end of the spring thaw into late fall. Frozen ground stops compaction through the winter, and spring load restrictions slow hauling while the frost comes out.

Across the Devils Lake Basin, runoff collects rather than drains because the basin has no natural outlet at normal lake levels. Since the wet cycle that began in 1993, the lake has risen more than 26 feet and flooded roads, approaches and farmland.

That history changes what a base course has to do. Ground that sat dry a generation ago can be saturated now, so a drive, pad or approach needs a clean stone layer under it to move water away from the fines.

Erosion follows the same pattern. Wave action works on a shoreline that keeps shifting, road shoulders and embankments stay saturated, and runoff cuts gullies where it drops into the basin.

Winters are long and severe, with deep ground frost and a hard thaw that heaves and softens gravel drives, approaches and township roads. Frost depth is set by the city or county rather than by a statewide table.

Materials Delivered in Benson County

Section 816, Table 816-01 sets the gradations for Classes 2, 3, 3M, 4, 5, 7, 8 and 13, and Section 302 names Class 5 as the traffic service aggregate.

Class 5 is crushed gravel base, and it is the one to start with on a driveway, parking pad or building pad. It is specified by class number on plans and ordered by that same number at the yard.

Below the base, drainage stone does the quiet work. Washed rock and 3/4 inch crushed rock both stay open, so water reaching them keeps moving instead of sitting against a foundation or under a slab.

For finish work, stone screenings bed pavers and flagstone and pack into a walking surface. Pea rock and river rock cover beds and paths, and black dirt or garden soil goes on top where something has to grow.

Choosing the Right Material

Benson County sits in the Devils Lake Basin, on rolling glacial till around a closed basin, with lake silt and clay and salt-affected ground on shorelines that have moved a long way in living memory. That ground is the starting point for any base or drainage choice.

Pierce County, in the Souris Basin, is a different story. Its ground is the flat to gently sloping bed of glacial Lake Souris, with clay and silt near the middle, wave-washed till around the rim, and wind-blown delta sand over much of the southern half of the old lake plain.

That difference matters at the base. Delta sand and lake-bed silt drain and compact differently from the till here, so a base that works on one side of the line is not automatically right on the other.

Wells County and Nelson County both sit in the Drift Prairie, on rolling glacial till with stone and boulders through it, washboard moraine and ice-thrust hills, and bands of sand and gravel in old meltwater channels. That is the same ground region as Benson County, so the base and drainage choices carry over.

Match the material to the job rather than to the county line. Clean stone for water, Class 5 where a compacted base is wanted, and riprap where moving water is the problem.

For a drive, pad or approach, have the grade ready before the truck arrives. A load tipped on soft, saturated ground is harder to work than one placed on a prepared surface.
