Martin Marietta gets OK for Colorado gravel plant

January 5, 2017

Colorado’s Boulder County commissioners yesterday approved Martin Marietta Materials' plan for constructing a processing plant and other structures on company's property southwest of Colo. 66 and North 61st Street.

The latest site plan — which revises a 1998 county-approved plan for the property — will allow Martin Marietta to process materials on a 5-acre area north of the St. Vrain River and south of the BNSF Railroad tracks, reports Times Call.

It is to include an employee building, a scale house, a motor control building, a machine shop, a quality control lab and five storage buildings as well as the processing plant.

Under the conditions the commissioners approved, Martin Marietta's can have up to 35-foot-tall lights mounted on the processing plant itself, but those lights would normally be used during daytime hours only.

Martin Marietta also had sought permission to install 15 25-foot-tall, pole-mounted lights on the property. Instead, the county Land Use Department staff recommended, and the commissioners approved, allowing eight 20-foot-tall pole-mounted light fixtures, provided those lights are turned off from the hours of 8 p.m. until 6 am.

Julie Mikulas, a Martin Marietta land manager, said after the meeting that there's no specific timetable for proceeding with getting building and floodplain permits for construction of the processing-plant facility but that it could come sometime later this year.
