Clark County Running Out of Aggregate

Construction groups such as the Southwest Washington Contractors Association are calling out Clark County for their dwindling supply of aggregate, used for road maintenance, industrial construction, residential construction, and the manufacturing of concrete, asphalt, and other products. With 955 permitted mines in 2010, you would think that there would be plenty of rock to go around, but, according to the contractors, this is not the case.

A reserve study conducted on Clark County shows that there is only 7 years of reserves, while the demand for aggregate continues to grow. Of the 25 “active” Clark County mines, only 12 are active with permitted reserves, and only 9 are producing aggregate material for construction, to be used on projects such as houses, hospitals, roads, bridges, etc. The reserve study also showed that 99% of permitted reserves are sourced from only 6 mines.

“Clark county is behind on assuring a sufficient two decade local supply of aggregate rock, which is a condition of the Growth Management Act,” said Ron Arp, President of Identity Clark County,” We’ll need to access everything that is accessible today and pursue additional capacity soon to meet our forecast needs for construction and infrastructure.”

With 93% if all national aggregate being transported via truck, Clark County may soon have to venture hours or more away in order to get the supplies they need. If it were to come to this, consumers could see higher costs, potentially even double the cost of their original bid, something that some contractors are already seeing locally.

How do you think Clark County will or should address the depleting aggregate supply?
