For driveways, 3/4u0022 crushed rock or crushed stone with a compacted base gives stability and good drainage. Decomposed granite (DG) is attractive for paths and low-traffic driveways if stabilized, while pea gravel is better for decorative front yards and low-traffic areas because it shifts under vehicle loads. River rock looks nice but is not recommended for driveways since it rolls and moves easily.

A 20x40 ft area at 3 inches deep is about 200 cubic feet, which is roughly 10 tons of aggregate (using the common rule of thumb that 1 ton ≈ 20 cubic feet). We recommend ordering 5% to 10% extra to allow for compaction, grading, and small waste, so plan on about 10.5 to 11 tons and round up to the next half or full ton to match delivery minimums.

Requirements vary by neighborhood; many homeowners can resurface a driveway without a building permit, but changes to curb cuts, drive apron size, or drainage can trigger city permits. HOA rules commonly restrict front-yard material changes or require design approval, so check Redwood City Planning Division and your HOA before starting. When in doubt, contact the city or your HOA to avoid costly rework.

Wet winters can cause washing, rutting, and settling if drainage and base are inadequate, while dry summers increase dust and weed growth. Properly sloped grading, a compacted base, and good edge restraint reduce washouts and settlement in winter storms. Because local soils and street runoff vary across Redwood City, address site-specific drainage to keep gravel stable year-round.

Expect light maintenance: remove weeds, rake to level high- and low-spots, and top up material as needed to restore depth (often every 1 to 3 years depending on traffic and erosion). Check edging and compacted areas after winter storms, and consider applying a pre-emergent or spot-treating weeds to cut down on growth. For driveways, occasional re-grading and minor additions of gravel keep the surface functional and attractive.

Gravel is usually less expensive upfront and naturally permeable, but it can shift, compact, and require periodic top-ups and more maintenance. Permeable pavers have higher upfront costs but provide durable, controlled infiltration with lower ongoing material replacement and can perform better on slopes or high-traffic areas. Choose based on your budget, desired look, expected traffic, and any local stormwater requirements; a mixed approach (stabilized gravel in low-traffic areas, pavers for driveways) is common.

Yes — local contractors and landscapers commonly offer full gravel installation including excavation, compacted subbase, geotextile fabric, and edging. Installed prices in the Bay Area vary with scope and site conditions; a typical installed gravel driveway range is roughly $4 to $12 per square foot depending on site prep and materials, so a 20x40 driveway could run several thousand dollars. Get 2 to 3 local bids and ask for itemized quotes listing base depth, fabric, edging, and material type.

Recycled crushed concrete is cost-effective for base layers: it compacts well and resists movement on slopes, making it a good choice under driveways or paths. Natural gravel or crushed stone is usually preferred as a top layer for appearance, drainage, and a cleaner finish. For many Redwood City sites, a crushed concrete base with a natural gravel wearing course blends performance and value.
