Alpine Landscape Materials in Alpine stocks decorative rock, gravel, topsoil, compost, and natural stone from its Tavern Road yard, serving both retail customers and licensed contractors since current ownership took over the facility in 2013. Hardscape supply orders for retaining walls and property-line projects pair with the post-and-rail installation services offered by Alpine Fence Inc. on Alpine Blvd, creating a single-corridor sourcing loop for East County build-outs. The retail yard functions as the public-facing arm of Mountain Materials Inc., which runs a separate wholesale trucking operation with a fleet ranging from ten-wheelers to truck-and-transfer rigs delivering aggregate across San Diego County. Fire-safe landscaping material for properties along the Cleveland National Forest interface includes Class A-rated decomposed granite and non-combustible river rock, sourced through the same supply chain that feeds Bob Wining Tree Service brush-clearance projects on Carveacre Road. Bulk bin inventory includes 3/4-inch gold decomposed granite, 1.5-inch Apache Brown river rock, premium planting mix blended at a 60/40 soil-to-compost ratio, and Class II road base delivered in quantities from half-yard scoops to 10-ton hauls.
