A foamy mixture of liquid soap, water, dirt and pulverized rock shoots from a nozzle on a drilling rig Monday in Columbia Point Marina Park in Richland.
It is part of a project to install four new light poles for a new sports field being developed at the park along the Columbia River, said Phil Pinard with the city of Richland.
Crews will be installing a 24-inch steel casing pipe for the concrete light pole bases that will be buried about 12 feet into the ground.
About 9 inches of fill dirt will then be applied and re-sodded to create the new playing field for soccer, football, lacrosse and other sports.
The project is expected to be done in early March.
