Inland Infrastructure LLC.

The public-works record runs from 2021 into 2026 and covers a long list of local agencies: the City of Spokane, Spokane County Public Works, the City of Spokane Valley, Cheney, Airway Heights, Millwood, Deer Park, the Spokane Transit Authority, Whitworth Water District #2, Spokane County Water District #3 and Consolidated Irrigation District #19. On most of that work the firm held the prime contract, and its filings show apprentices on the job. The state insures its crews under classes for site work, concrete and underground utilities, which is a closer description of the work than its general contractor registration. The state lists Marshall Sampson and Walker Construction, Inc. as principals since 2021. This is a civil and infrastructure outfit. It fits municipal road and utility projects that carry prevailing-wage requirements, water district upgrades, and site preparation or concrete packages on commercial developments. A homeowner planning a kitchen remodel or a job that hinges on a manufacturer-backed residential warranty will find it a closer fit to look elsewhere. Property owners and builders with larger dirt, concrete or utility scopes, on either side of the state line, are the more natural match. Spokane's housing stock spans early-1900s neighborhoods on the South Hill and in the older parts of the city alongside newer subdivisions in Spokane Valley, Liberty Lake and the north side. On older lots, site and utility work often runs into aging clay or cast-iron sewer laterals, shallow or undocumented lines, and tight access between houses. Newer developments bring a different set of questions about grading, drainage and connections to district water systems. Before hiring for excavation or concrete, find out who owns the line you're working on, the city or a water district, and get utilities located first.
