Driveway gravel in Nampa handles winter and spring conditions
Nampa's climate and soils create distinct challenges for driveway construction. The city experiences mild winters but spring runoff and summer heat both stress unprepared surfaces. Driveway Gravel in Nampa works best when you match the material to the site and compact it properly. We offer two proven materials for Nampa: #57 Crushed Stone and Asphalt Millings. These products are sold by the ton with free delivery offered at 15 tons or more to Nampa addresses.
Choosing the material and size for your driveway
#57 Crushed Stone is a blend of angular pieces and stone dust that compacts firmly and sheds water quickly. The interlocking aggregate pieces resist displacement and settle minimally over time. Asphalt Millings, reclaimed from road resurfacing, bind together over time and create a smooth driving surface that resists displacement and maintains traction. Both options are available by the ton in Nampa. Start with 4 to 6 inches of base material, depending on your soil condition and expected traffic from trucks or equipment. Nampa's varied soils often benefit from the deeper application.
Calculating depth, base and how much to order
Measure your driveway length, width and desired depth in inches. The formula is straightforward: multiply length feet times width feet times depth inches, then divide by 324 to get cubic yards of space needed. A 20-foot driveway that is 12 feet wide and 4 inches deep equals about 3 cubic yards, or roughly 4.5 tons of aggregate material. At 6 inches deep, the same driveway requires approximately 7 tons.
Use the calculator to find your exact tonnage based on your dimensions. At 15 tons or more, delivery in Nampa includes free shipping included with your order. Smaller orders carry a location-based delivery fee and arrive in 1-2 business days. Confirm your delivered price when you enter your ZIP code at checkout.
Local conditions affect how your driveway performs
Nampa soil tends toward clay and silt, which hold moisture and cause settling under weight. Grade your driveway to slope away from structures so water drains naturally and quickly into surrounding soil. Compact each 2-inch layer of material before adding the next layer using a hand tamper or power roller to lock the pieces in place and prevent rutting under vehicle weight. In Nampa's spring, melting snow and rain add weight that unsettled material cannot support. Proper slope and compaction are the keys to a driveway that lasts 3-5 years before needing new material or topping.
Delivery and getting started with your driveway
Order your material online and we deliver to your Nampa address by truck. Unload happens on-site, positioned where you direct the driver for easiest spreading. Plan to finish compaction and edging the same day as delivery, while the weather is dry and the ground is workable. Avoid placing gravel during or immediately after rain, when compaction becomes difficult and uneven settling occurs across the surface. Weather coordination is essential in Nampa for the best installation results.

Is #57 Crushed Stone better than Asphalt Millings for a driveway?
Both work well in Nampa if compacted properly. Crushed stone costs less and stays loose longer, making it easier to rake and adjust. Millings bind together over time and create a firmer surface with less displacement.
How deep should my driveway gravel be?
Install 4 to 6 inches total depth. Apply base material in 2-inch layers, compacting each one before adding the next. Compact firmly to prevent the driveway from rutting under heavy vehicles or settling after rain.
Does Nampa weather affect gravel driveway longevity?
Spring runoff and summer heat do stress uncompacted driveways in Nampa. Slope your driveway away from buildings to shed water quickly. A well-built gravel driveway lasts 3-5 years before needing topping.
How much gravel do I need for a 20x12 driveway?
At 4 inches deep, a 20-by-12 driveway needs roughly 4.5 tons. At 6 inches, it needs about 7 tons. Use the calculator to confirm based on your exact dimensions.

Can I mix #57 Crushed Stone and Asphalt Millings?
Yes. Using a crushed stone base and millings on top works well. The stone provides drainage and stability while the millings create a finished, compacted surface. Compact each layer separately.
Do I need to prepare the soil before placing gravel?
Yes. Remove grass, weeds and debris. Level the ground and slope it away from buildings. For soft or muddy soil, add 2-3 inches of crusher run or base gravel first, then compact before applying your finished material.
