Excavation & Grading

Expert mass excavation and precision grading are the cornerstones of any successful construction project. For our clients in Washougal, we provide meticulous sitework for projects of any scale, from sprawling commercial centers to multi-lot residential subdivisions. Our skilled operators use state-of-the-art equipment to create stable, perfectly graded building pads and expansive parking lots. We understand the unique topography and soil conditions of Clark County, ensuring that every site has proper drainage and a flawless base ready for vertical construction.

Preparing a site for new development often requires clearing away the old. Our professional demolition services in Washougal safely and efficiently handle every aspect of site preparation, including full structural teardowns, concrete removal, and the proper abandonment of old septic systems and wells. We meticulously clear land of trees, brush, and unwanted debris, transforming overgrown or previously used parcels into clean slates. Every step is performed in strict adherence to safety protocols and environmental standards, ensuring your Washougal site is ready for its next chapter.

Reliable infrastructure begins below the surface. Legacy 6 Inc. specializes in the new installation, repair, and maintenance of essential underground utilities for projects throughout Washougal, WA. Our experienced crews are proficient in laying complex networks of water lines, sewer mains, and storm drainage systems. Whether for a large commercial development requiring significant capacity or a new residential subdivision needing community-wide infrastructure, we ensure every connection is sound and every system is built for long-term, trouble-free service.

The varied terrain of the Pacific Northwest makes engineered retaining walls a critical component for maximizing land use and ensuring site stability. We design and construct robust retaining walls that effectively manage soil erosion, prevent landslides, and create level, functional spaces on sloped properties. Our expertise allows developers and property owners in Washougal to overcome challenging landscapes, turning previously unusable inclines into valuable areas for buildings, parking, or amenities.

Road & Subdivision Construction

Legacy 6 Inc. is a trusted partner for residential developers building the communities of tomorrow. We have the capacity and experience to build the complete foundational infrastructure for new subdivisions, from intimate 10-lot developments to large-scale 100-lot communities. Our services include initial land clearing, mass grading for roadways, installation of all underground utilities, and construction of curbs, gutters, and sidewalks. We deliver a site that is fully prepared for homebuilders to begin their work.

The success of any major construction project hinges on logistics. Our internal fleet of over 150 units, including super solos, truck and pups, transfers, side dumps, and lowboys, is a significant asset for our Washougal clients. By managing our own trucking and material hauling, we eliminate dependence on third-party schedules and ensure that soil, aggregate, materials, and heavy equipment are moved efficiently. This control over logistics keeps your project on schedule and minimizes the delays that can impact your bottom line.
