Asphalt Paving in Grand Mound, WA

Asphalt paving in Grand Mound serves a community that blends rural homes with freeway businesses. Jotham Weeks Goodell named and founded Grand Mound in 1851 after a 125-foot tree-covered hill nearby. It has been a census-designated place since 1990, and it counted 3,301 residents in 2020 on about 3.9 square miles at 167 feet. Prairie Creek, the only stream in the community, flows to the Chehalis River, and Scatter Creek runs just to the north.

Traffic from the freeway

Grand Mound sits along Interstate 5, and Great Wolf Lodge, a 398-room resort with an indoor waterpark, opened here in March 2008. Commercial lots, gas stations and travel businesses along the corridor see heavy traffic and delivery trucks. Those lots need thicker sections at entrances and truck routes, good drainage to catch basins, and regular crack sealing and restriping. We patch, overlay and rebuild commercial lots and phase the work to keep businesses open.

Rural and residential driveways

Away from the freeway, many homes have longer driveways, and plenty are gravel. Converting to asphalt starts with grading and compacting the existing rock, adding crushed rock where it is thin, and paving to a thickness that fits the vehicles. Near creeks and low ground, we expect wetter soils and plan for extra excavation.

Prairie soils

South Sound prairies formed on glacial outwash of sand and rounded gravel. It drains quickly, which helps pavement, but it can be loose, so careful compaction and edge support matter. In the low areas along Prairie Creek, finer soils can hold water through the winter.

County permits

Grand Mound is unincorporated, so road work generally falls under Thurston County. The county calls a new or relocated driveway connecting to a county road an encroachment and requires a permit for it. Highway frontage may involve the state. We sort out which agency applies before scheduling any work at the road.

Upkeep that pays off

Whether it is a home driveway or a commercial lot, sealing cracks before the fall rains and sealcoating every few years in dry weather are the cheapest ways to make pavement last longer here.
