Start with 3/4 minus for a driveway, pad or shed base. It is crushed rock graded down to fines, so it compacts and locks up under a vehicle.

Materials for Pleasant Hill Projects

Water is the thing that moves ground around here. Winter rain sheets off bare silt, cuts into banks and pulls at swale edges and culvert outlets.

Coarse, open stone is what holds those places together.

RipRap is the heavy end of that work. It armors stream banks, culvert outlets, pond edges and cut slopes against winter runoff, and it is specified by class from Class 50 up to Class 2000.

Large River Rock suits dry creek beds, splash pads under downspouts and bank work where small stone would wash out. It is rounded, water-worn stone rather than crushed quarry rock.

Drain Rock is washed and open so water moves through it instead of sitting. Use it in French drains, curtain drains, footing drains, drywells and downspout runs.

3/4" Crushed Stone, often called 3/4 clean, is angular rock with the fines screened out. It goes in drainage trenches, retaining wall backfill and construction entrances, and it bridges soft wet ground.

For a compacted surface, 3/4 Minus is the standard base under driveways, parking pads, shop floors and shed bases. 1/4 Minus beds pavers and flagstone and tops a compacted base.

Ground and Conditions in Pleasant Hill

Across the Willamette Valley and Portland Basin, the ground is tight. Deep slackwater silt sits on the valley floor, with red clay and silty clay loam in the foothills and river gravel along the waterways.

That ground sheds water slowly. With 35 to 45 inches of rain a year falling almost entirely between November and March, a seasonal high water table shows up in the lowlands and soft subgrade follows.

Timing matters as much as material. Portland treats October 1 to April 30 as the wet weather season and requires bare ground to be stabilized within two days, against seven days from May 1 to September 30.

Base and paving work concentrates in the dry season for that reason. Plan your delivery around the window you are actually building in, and let the ground dry before you place a compacted base on it.
