CONCRETE & ASPHALT
IN LEAVENWORTH, KS.

Max Paving is the prime contractor on the City of Leavenworth's 2027 CCLIP project on 4th Street, and our crews started the concrete work in October 2026. The city's notice to contractors, Project No. 2025-007, titles that work 4th Street Curb and Sidewalks, Seneca to Cheyenne, and calls for reconstruction of curb and gutter, concrete sidewalk, ADA compliant sidewalk ramps at multiple intersections, and an 8-inch concrete alley. For everyday driveway and sidewalk work in the right-of-way, the city points to its Manual of Infrastructure Standards, which asks for at least 6 inches of concrete where a walk crosses a driveway or meets the street at an access ramp. Curb that gets cut for a new driveway or ramp is replaced between the nearest construction joints, and ramps are built at the maximum allowable grade so water stays in the gutter line. Walks and curbs also call for the city's standard 4K Kansas City Metropolitan Materials Board mix with granite or trap rock aggregate, and the city inspects sidewalk work before anything is placed.

Colonel Henry Leavenworth founded the fort in 1827 on the bluffs of the Missouri River, according to the city's history page, and the Kansas Geological Survey says loess, a wind-blown silt, lies mainly along those bluffs in Leavenworth County in deposits from a few feet to 60 feet thick. A USDA soil query at a downtown point comes back as Knox silt loam, a well drained loess soil of strongly dissected hills and bluffs where the USDA lists slopes anywhere from 2 to 35 percent. Points we checked west and south of downtown come back as Sharpsburg silty clay loam, which the USDA puts at 36 to 42 percent clay in its control section. Census estimates show more than a quarter of the city's housing was built in 1939 or earlier, so plenty of driveways and walks sit on lots laid out generations before the current manual was written. We check the base and the drainage on every job, and on a sloped lot we set the grade so runoff moves past a new slab instead of working its way under it.

On the industrial side, the city's 80-acre Business and Technology Park opened in 2018 near the older business park along Eisenhower Road. In June 2026 the Leavenworth County Development Corporation announced that a Texas-based machinery company had bought a five-acre site in the Gary Carlson Business Center, which the county port authority developed in 1989, for a planned 20,000-square-foot facility. Sites like those need truck lanes and dock aprons that hold up under loaded trucks, and heavy-duty concrete for that work typically runs 8 to 10 inches thick depending on the loads, the ground, and other factors. We do the excavation and base work under that concrete ourselves, drainage included, with our own equipment. The crews on the 4th Street job are the same crews that pour our residential driveways and commercial lots. There is no single minimum job size because it depends on the type of work, and Wendell or Daniel can look at your site and put together a free written proposal.
