Clarion County spans two ground zones. Clarion, Rimersburg, East Brady and Knox sit on shale, siltstone and clay-rich soils cut by steep valleys, much of it over old underground coal mines. Vowinckel and Fryburg sit higher, on stony uplands with deep, steep-sided valleys.
Ground Conditions Across Clarion County
Start with water. Rain and snowmelt run hard down steep hillsides here, and where that water goes decides whether a base holds or breaks up.
In the plateau hills around Clarion, Rimersburg, East Brady and Knox, water soaks into clay layers on slopes. That is the main landslide trigger in the region, so roof and drive runoff needs a controlled path on hillside lots.
Higher ground near Vowinckel and Fryburg sheds runoff fast off steep valley sides. Concentrated flow hits roadside ditches, culverts and low drives, and can set off debris slides on mountainsides after extreme rain or rain on snow.
Winter brings repeated freeze-thaw cycles in both zones. Wet, clay-rich soils soften and heave, so a thin or poorly drained base breaks up. Frost depth runs about 36 inches in the plateau hills and 36 to 42 inches in the mountains, set by each municipality.
Time the work around the season. Base, driveway and paver work runs from spring, once ground thaws and dries, into late fall in the plateau hills. On the higher ground, keep base stone off frozen or muddy ground.
Materials Delivered in Clarion County
Local yards still sell by the older Pennsylvania names: 2B for #57 and 1B for #8.
2A Modified: the Pennsylvania base stone
2A modified is the trade name for a 2A-type base with extra fines added.
The fines are the point. They let the stone compact into a hard, tight surface that sheds water instead of shifting under tires. That matters on the clay-rich slopes around Clarion and Rimersburg.
Top a compacted 2A modified base with driveway gravel for a finished drive surface. For a walkable path, use walkway gravel over the same base.
Washed stone, sand, soil and decorative rock
Washed stone drains. Use #67 stone where a slightly smaller clean stone than #57 is wanted, and #89 crushed stone for joints and tight bedding. Drain Rock handles french drains and downspout runs, and local yards usually sell clean stone such as 2B for that job.
For bedding and mixes, Mason Sand goes into brick and block mortar, paver joints and play areas. Washed Sand serves concrete, leveling and bedding under pavers and slabs.
Decorative options include River Rock and Large River Rock for dry creek beds and erosion work. 3/8" Natural Pea Gravel is rounded, so it stays loose underfoot on walkways and play areas.
Delivery Across Clarion County
Bulk material arrives by dump truck and is tipped at the site. Clear the drop area first. Keep overhead lines, parked cars and low branches out of the way.
Order online. Choose the material, enter a quantity by the ton or the yard, then confirm a delivery date at checkout. Not sure how much you need? Use the calculator to size the load before you order.
Delivery covers Clarion, Rimersburg, East Brady, Knox, New Bethlehem, Sligo, Shippenville, Strattanville, Vowinckel, Leeper, Fairmount City, Fryburg, Kossuth and Lickingville.
On hillside lots, plan where the truck can turn around and where the pile should sit. Steep drives and soft spring ground are worth checking before the drop.
Choosing the Right Material
Start with the ground under the job. Base choice follows drainage, slope and season more than it follows preference.
Venango County to the west spans the plateau hills and the high plateau. It shares Clarion County's zones, so the ground is similar. Expect the same 2A modified base for drives and the same clean stone for drainage.
Forest County to the north sits on the high plateau, with stony soils on broad uplands cut by steep valleys. That ground drains differently from the clay-rich slopes around Clarion, so plan on more clean stone for culverts and ditch outlets.
Butler County to the south spans the plateau hills and glaciated ground. Where it shares this county's zone, the base and drainage choices match. Typical projects there lean toward drive and pad work on the same 2A modified base.
Pick by job: 2A modified for anything that carries weight, 2B or #57 for water, screenings for bedding, topsoil for the finish. Match the stone to the water first.
