What We Are Planning

We are moving our existing facility in Covington to Maple Valley, along State Route 169, where we’ll produce high-quality asphalt used for local roads, highways, schools, businesses and residences. Once we are permitted, construction will take about 6-8 months. We will use only one-third of the property, currently occupied by another industrial company. Our new facility will help us respond to the needs of our local customers while we protect local air and water quality using industry-leading environmental technology. Download our FAQ

Why We Chose This Location

The Lakeside property on State Route 169 is already zoned for Industrial Uses, and our asphalt plant is an expressly permitted use, so it was attractive when the owner of our Covington site decided to develop the property. Like others, Lakeside strongly believes that everyone should be able to rely on zoning. Furthermore, the Maple Valley site is ideal as it gives us convenient access to customers who need asphalt to create projects for families, companies, the community, and many others.

How We’ll Support the Local Economy

Our plant in Maple Valley, when fully operational, will create approximately 25 to 30 well-paying, full-time jobs. Lakeside’s plant will also generate significant tax revenues for local schools, first responders, public parks and other critical community needs. Asphalt is used everywhere – in businesses, residential communities, and transportation infrastructure – and by locating our plant near these uses, Lakeside supports the companies that drive everyday commerce and community improvements.

How We Will Protect Local Water Quality

Asphalt is an inert material and does not harm people or fish. In fact, asphalt liners are used in drinking water reservoirs and in rearing ponds in fish hatcheries. Lakeside operates many asphalt plants across the region, in both rural and urban locations. Our Maple Valley facility will be highly sustainable, featuring the latest industry technology to ensure clean stormwater run-off to protect salmon and other fish that rely on clean water. Lakeside will meet or exceed the rigorous regulations established by state and local environmental agencies.

How We Will Protect Local Air Quality

Asphalt plants do not emit harmful pollutants according to studies conducted by the U.S. EPA and other air quality regulators. Our stack in Maple Valley, like all our asphalt plants, will emit steam, the result of drying the rock used to produce the asphalt. Our industry-leading technology and best management practices will enable us to protect local air quality in a way that meets or exceeds the rigorous regulations established by state and local environmental agencies. Our asphalt plant will produce less emissions over a year’s time than a typical commercial bakery produces in a month.

How You Can Support Us

The King County Council has just passed a Moratorium on new applications for industrial uses on Industrial Zoned Properties within a quarter mile of the Cedar River in the Maple Valley area of South King County. Without warning or notice to Lakeside Industries, the Moratorium was clearly aimed at the Lakeside proposal to relocate its Covington Asphalt Plant to a large Industrial Zoned property along State Highway 169. While there are no immediate neighbors at the site, some protested loudly and generated a large, uninformed social media response from people all over the region
and the country.
