Materials for Baldwin Park Projects

Start with the coarsest stone and work down to the fines. Heavy drainage gets big open stone; bedding and joints get small washed sizes.

• Drain Rock for French drains, drywells, downspout runs and the drainage layer behind a retaining wall. That is the material most Baldwin Park drainage jobs are built on.
• 3/4" Drain Rock, also called #57 stone, for drainage trenches. It is clean stone with no fines, so water moves through it instead of sitting on top.
• #4 Crushed Stone for trench bottoms and heavy drainage where a bigger void space is wanted.
• RipRap, also called rock slope protection, for armoring slopes and culvert outlets against winter storm runoff.
• Stone Screenings, or DG, for paths and patio surfaces laid over a compacted base.

Under all of it sits Class 2 base, the standard California base material. Caltrans specifies it as Class 2 aggregate base, and it is what you compact under pavers, slabs and driveways. Some crews order recycled base rock for the same job; processed reclaimed concrete and asphalt are allowed in aggregate base. Others ask for crusher run when they want a binding mix, though Class 2 base is the usual call here.

Ground and Conditions in Baldwin Park

The long, warm, dry season here suits base and paver work for most of the year. Winter storm days are the main interruption, so timing a delivery around the forecast saves a wasted load.

Soils across these valleys run from Top Soil to clay, and expansive clay is common. Clay swells when it gets wet and shrinks and cracks when it dries, which moves anything sitting on top of it. That is why a compacted Class 2 base matters under paving, and why drainage matters even more.

Rain arrives in a few winter storms after a long dry season. It runs off hardscape, hard dry ground and clay fast, so downspout runs, French drains and drywells need clean washed stone that will not clog. Where slopes and canyon edges shed water, rip rap holds the soil in place. Get the drainage layer right and the base above it stays put.
