Materials for Half Moon Bay Projects

Start with grade. Raise a low pad with Fill Dirt before anything compacted goes down. Fill Dirt builds up the subgrade so your base has something solid to sit on.

Then cap it with Class 2 Base, also called Class II base rock. This is the California base material, specified by Caltrans as Class 2 aggregate base. Recycled Class 2 base from Road Base or asphalt does the same job under drives, patios and slabs.

For drainage work, Drain Rock goes in French drains, drywells and behind retaining walls. It is clean stone with no fines, so water moves through it instead of pooling.

Finish paths and patios with Stone Screenings, or DG, laid over a compacted base. For planting areas, Top Soil rebuilds beds over heavy clay or sandy native ground.

Ground and Conditions in Half Moon Bay

Soils here change over short distances. Sandy dune and beach ground sits along parts of the shoreline, while heavy clay spreads through the Coast Range valleys and hills. That clay cracks when dry and swells when wet, which is what breaks an under-built base.

Rain falls from late fall to spring, much of it in a few large winter storms. Sandy ground takes it fast. Clay holds it or sheds it downhill, and that runoff reaches slopes, creek banks and culvert outlets.

Armor those spots with RipRap, called rock slope protection when it is placed on a slope. The dry season from late spring into fall is your window for base, driveway and paver work. Summer fog near the shore is fine to work in; saturated clay is not.
