Stone, Gravel and Topsoil Delivery in Elizabeth, NJ

Wet Ground Near Sea Level

Udorthents, organic substratum, 0 to 8 percent slopes, is the map unit the USDA survey shows at the center point of ZIP 07201. Udorthents are reworked soils, moved and graded by people, and an organic layer underneath means soft ground that compresses under load. A heavy pad or a stack of pavers laid on it without preparation can sink slowly at one corner.^[1]

Pawcatuck, a wet soil series, accounts for 5 percent of that map unit, and another 5 percent is mapped as urban land. Those small shares hint at how mixed the ground is from one yard to the next.^[1]

The survey rates the soil very poorly drained and places it in hydrologic group D, with very slow infiltration and high runoff. Water sits on ground like this after every storm. Any patio, path or parking spot needs a planned way to move water off and away, and a hard surface alone does not provide it.^[1]

Loamy sand is the texture listed, and shrink-swell is low, 0 percent. The trouble on this ground is water and softness, not swelling clay.^[1]

Deeper down, the USGS state geologic map puts the Passaic Formation at the ZIP's center point, Early Jurassic siltstone and shale. Weathered shale under wet fill can stay damp for a long time after rain, which is one more reason the base on top needs to drain on its own.^[2]

The USGS elevation service reads just 10 feet above sea level for the ground at the mapped center of the ZIP.^[3]

A Parking Pad That Does Not Sink

Start by digging out the organic, spongy top layer as deep as you reasonably can. Lay a heavy woven geotextile across the bottom and up the sides so the base cannot push down into the soft ground below.^[1]

Build the base from Road Base or Crushed Concrete, spread in thin lifts and compacted each time. On very poorly drained ground, a perforated pipe wrapped in Drain Rock along the low edge of the pad gives water a path to a drain or a lower spot in the yard. Check the fall with a level before you backfill, because a pipe that runs uphill holds water instead of moving it.^[1]

Top the pad with #57 Crushed Stone or 3/4" Crushed Stone, which stays open enough to let rain through to the drained layer beneath. Asphalt Millings make a firmer, darker surface that packs in warm weather and resists ruts from a parked car.^[1]

Plan the pad a few inches higher than the lawn around it. On soft, low ground, a raised pad with a gentle slope away from the house stays dry when the yard is wet, and the edge stone has room to drain.^[1]

Snow, Rain and Freeze at the Newark Gauge

Weather here is read at the NOAA normals station at Newark Intl AP, NJ, about 1 mile away, which averages 46.6 inches of precipitation a year. On group D soil much of that runs off instead of soaking in, so every downspout needs a planned exit.^[4]

The Newark airport station averages 31.5 inches of snow a year. Snow piled on a gravel pad melts into the base, and an open, clean stone such as #57 Crushed Stone lets that meltwater drain rather than freeze inside the surface. Pick one corner of the pad for the shovel pile, ideally the corner nearest the drain.^[4]

Newark Intl AP records a low of 32 F or colder on 80 days in a typical year. A base that holds water heaves on freezing nights, which is one more reason to keep fines out of the top layer on wet ground.^[4]

The median last spring freeze at Newark falls on April 2, and the median first fall freeze on November 10. Base work goes best in the drier weeks of late spring or early fall, when the ground is firm enough to compact.^[4]

Small Yards and Raised Beds

ZIP 07201 holds 10,404 housing units, and 7 percent of them are detached single-family houses. Elizabeth counts 48,976 housing units in all, with 14 percent detached.^[5]

The median home in the ZIP was built in 1961, against a median year of 1957 for the city. Owners live in 20 percent of occupied homes in ZIP 07201.^[5]

Planting straight into very poorly drained soil drowns most roots. Raised beds filled with Garden Soil or a blend of Topsoil and Compost lift roots above the wet layer. A few inches of Black Shredded Mulch or Brown Shredded Mulch on top keeps weeds down and holds moisture in the bed, not the ground below.^[1]

For a side passage or a narrow back yard, River Rock or Pea Gravel over fabric gives a clean, low-care surface that never turns to mud. Slope it slightly toward the street or a drain. A row of planters filled with Garden Soil along a fence adds green without digging into the wet ground at all.^[1]

Drain Rock or River Rock for a Soggy Corner

Drain Rock is the working choice for a soggy corner. It is clean, sized stone with open gaps, so it fills a trench or a dry well and lets water move through. Wrap it in fabric so silt does not clog it.^[1]

River Rock looks better on top. A shallow channel lined with fabric, filled with Drain Rock and capped with River Rock, carries water across a yard on group D ground and still reads as a garden feature. Lay the channel along the path water already takes after a storm, then deepen and widen that path rather than inventing a new one.^[1]

A dry well works where there is no lower spot to drain to. Dig a pit, line it with fabric, fill it with Drain Rock and cap it with soil or stone. On ground this wet it fills during a long storm, but it buys time for the water to leave slowly instead of standing on the lawn.^[1]

Narrow Walks and Side Passages

A side passage between two buildings rarely sees sun, and on very poorly drained ground it can stay damp for days. Moss and mud take over bare soil there, and a concrete walk laid on soft fill tends to crack and tilt as the ground beneath it settles.^[1]

A gravel walk handles that better. Dig out a few inches, lay fabric, compact a thin layer of Road Base, and finish with 3/8" Crushed Stone or Pea Gravel. The small stone is comfortable underfoot, drains at once, and can be raked level again after a hard winter instead of being broken out and poured anew. Stone Dust Screenings pack firmer for a wheeled trash bin, though they hold more water on the surface.^[1],[4]
