Materials for Descanso Projects

Coarse stone does the heavy work on slopes and banks. Work from the biggest rock down to the fines, and match the size to the job.

Rip rap for slope and bank protection

Rip rap, also called rock slope protection, armors slopes, creek banks and culvert outlets against winter storm runoff. Caltrans specifies placed rock on slopes as rock slope protection. Use it where water leaves a pipe or cuts a bank. RipRap

Cobble for swales and dry creek beds

Cobble, or large river rock, slows runoff in dry creek beds and swales. It also handles heavier decorative and erosion work. Large River Rock sits well at the bottom of a drainage swale.

Drain rock for trenches and retaining walls

Drain rock is clean stone with no fines, so water moves through it. Use it in French drains, drywells, downspout runs and behind retaining walls. Drain Rock keeps a wet slope from pushing on a wall.

3/4 inch drain rock for drainage layers

3/4 inch drain rock, also called #57 stone, suits French drains, drainage trenches and drainage layers. It is washed clean, so it drains instead of holding water. 3/4" Drain Rock

Class 2 base for drives and pads

Class 2 base, also called Class II base rock or Class 2 aggregate base, is the standard California base material. Caltrans specifies it as Class 2 aggregate base. It goes under driveways, parking pads, pavers and slabs. Class 2 Base compacts hard and sheds water off the surface.

Finer material for paths and beds

Stone Screenings, or DG, packs firm for paths, patios and low-water ground cover. Lay it over a compacted base. Stone Screenings needs that base to stay put. Top Soil rebuilds planting areas over thin rocky ground.

Ground and Conditions in Descanso

Timing decides the schedule here. The working window runs late spring to fall. Snow and frozen or saturated ground stop most base and excavation work in winter at the higher towns, and the spring thaw leaves unpaved ground soft.

Book base and excavation work inside that window. A pad cut in wet ground will not compact, and it will move once traffic hits it.

Freeze-thaw is a real design factor in these mountain towns. Freezing nights are routine through winter, and snow is heavy and lasting at the highest towns. Frost depth is set by the local building department, commonly 18 to 24 inches in mountain towns. That depth drives how far down you dig before base goes in.

The ground itself is mostly thin, rocky soil over granite, volcanic or metamorphic rock. Coarse and sandy where granite has weathered. Water runs fast off rock and thin soil on slopes, then collects where drives and pads cut across it. Plan a drainage layer and an armored outlet before the first storm, not after.

Questions About Stone in Descanso

What stone should I use for drainage in Descanso?

Start with clean stone that has no fines. Drain rock and 3/4 inch drain rock, also called #57 stone, suit French drains, drywells and drainage layers because water passes straight through. For slope and bank protection, use rip rap, which Caltrans specifies as rock slope protection. Cobble slows runoff in swales and dry creek beds.

What should I have ready when the truck arrives?

Clear the access route and mark the dump spot. The ground needs to hold a loaded truck, so check for soft or saturated areas first. Know where you want the pile, since bulk loads drop where the driver can reach. Have someone on site to direct placement, and keep the delivery window open.
