Gravel, Rock and Sand Delivery in Lake Havasu City, AZ

Desert soils on sloping ground

The USDA survey maps the Chuckawalla-Riverbend families complex, 2 to 15 percent slopes, at the ZIP's center point. A families complex groups related desert soils that are mixed too closely to map apart. Slopes of 2 to 15 percent run from gentle to fairly steep, so many lots have some fall to them.^[1]

The geologic map shows Quaternary surficial deposits, undivided, made of sand, silt and clay. These are young layers laid down by water and wind. They dig easily in most places, though loose layers can cave in a deep trench. The ground at the center point stands 550 feet above sea level.^[2],[3]

Ground of sand, silt and clay on a slope can wash when a storm finally hits. Fine material moves first, so bare soil on a sloped lot may lose its surface in one heavy rain. Rock cover and planned drainage keep it in place.^[1],[2]

A very dry climate at the local station

The NOAA normals station at Lake Havasu City, AZ, about 2 miles away, averages 4.2 inches of precipitation a year and 0.0 inches of snow. That is very little water. Plants live on irrigation, and lawns are rare. When rain does come, it can arrive as a short, heavy storm that the dry ground cannot soak up fast enough.^[4]

The station counts just 1 day a year with a low of 32 F or colder. Frost damage is not a concern for gravel here. Heat, sun and wind are what a desert yard has to handle, and the right stone choice helps with all three.^[4]

Rock yards that look good and last

A full rock yard starts with clearing weeds and grading the ground so it falls away from the house. Lay a woven landscape fabric to block weeds, cut openings for each plant, and spread the rock in an even layer. On a sloped lot, place larger rock at the downhill edge first so smaller stone does not creep down.^[1]

River Rock gives a smooth, rounded look and comes in mixed colors. 1-1/2" Crushed Gravel and #57 Crushed Stone give an angular texture that stays in place better on a slope. Decomposed Granite packs into a firm surface for paths and patios. 3/8" Crushed Stone and Pea Gravel make softer, smaller cover around plants.^[1]

Light-colored stone reflects heat and keeps a patio cooler underfoot. Dark rock holds heat and can warm the air near a wall. Many yards use pale Decomposed Granite where people walk and darker River Rock in planted areas for contrast.^[4]

Handling a desert storm

With only 4.2 inches of yearly precipitation at the station, storms are rare, but they matter. Water runs off rock roofs, driveways and patios fast. A dry wash lined with River Rock and edged with Riprap carries that water across the yard and looks natural the rest of the year.^[4]

Plan the wash before any rock goes down. Follow the path water already takes across the lot, since a storm will find its old route even under fresh stone. Dig the wash a little lower than the ground beside it, lay fabric, and place the largest rock along the outside of each bend, where the flow pushes hardest. Fill the floor with River Rock and tuck smaller stone between the big pieces so the bed locks together.^[1],[4]

On slopes in the 2 to 15 percent range, set a few low checks of Riprap across any line where water gathers. They slow the flow and catch fine soil. Under downspouts, a small pit of Drain Rock gives water a place to soak in rather than cut a groove.^[1]

Keep fine materials such as Stone Dust Screenings and Decomposed Granite out of a wash, since fast water carries them away. Use them on paths that sit above the flow line, with a slight cross slope to shed rain.^[2]

Choosing between Decomposed Granite and Pea Gravel for a patio

Decomposed Granite is the firm option. Spread over a compacted base, wetted and rolled, it sets into a tan surface that chairs, tables and grills can stand on. It drains across the top rather than through, so it needs a slight slope.^[4]

Pea Gravel is the soft option. It drains straight down, stays cool in color and feels good underfoot, but chairs sink and it rolls. It suits a fire pit area or a quiet corner more than a dining patio. Edge either one with steel or set stone so it stays in place.^[4]

Drives, RV pads and beds

Many lots here park a boat, a trailer or an RV. A pad for heavy loads needs fabric, a thick compacted layer of Road Base or Crushed Concrete, and a top of 3/4" Crushed Stone or Driveway Gravel. Railroad Ballast makes a strong bottom course for the heaviest pads. Asphalt Millings pack into a firm, dark surface.^[1]

Garden beds in dry ground need help holding water. Garden Soil in planting holes and raised beds gives roots a better start. Topsoil fills low spots. Wood Chips break down slowly and hold moisture under shrubs. Brown Shredded Mulch, Black Shredded Mulch and Red Mulch suit shaded beds near the house.^[4]

Pools, side yards and upkeep

Many backyards here are built around a pool. Stone near a pool should be clean and heavy enough that wind does not blow it into the water. River Rock and 1-1/2" Crushed Gravel stay put, while fine Decomposed Granite and Stone Dust Screenings can track onto wet feet and into the pool. Keep those finer materials farther from the deck.^[4]

Side yards between houses are often long, narrow and hot. A cover of 3/8" Crushed Stone or #57 Crushed Stone over fabric makes them easy to keep and gives a firm path to a pool pump or an air conditioner. Walkway Gravel packs a bit smoother if the side yard is a main route to the back.^[4]

A rock yard still needs a little care. Blow leaves and dust off the rock a few times a year, pull the odd weed that roots in blown-in soil, and rake stone back into place after a storm. A thin top-up of the same rock every few years keeps the color fresh and covers fabric that has worked its way up.^[4]
