The City of Snoqualmie is faced with several challenges relating to the environmental forces affecting various parts of the city. Much of the Snoqualmie Valley has very poor soil bearing capacity. In many areas, liquefaction potential is moderate to high. As the elevation changes, soil conditions generally improve. However, snow loads and wind exposure factors can also increase.
