Weld County Commissioners Approve Rezoning

On July 22, 2020, the Weld County Board of County Commissioners granted Rock and Rail’s application for rezoning the land on which it is operating from agricultural to heavy industrial.

BOCC Resolution Granting Rezoning

Rezoning Application

In late March 2020, Rock and Rail submitted an application to Weld County to rezone the land at the intersection of Hwy 34 and CR 13 where they are currently operating an aggregate processing and concrete manufacturing plant. They applied for rezoning of the land from Agricultural to I-3, Heavy Industrial.


If approved, this change in zoning would allow Rock and Rail (Martin Marietta Materials) to use the land for many heavy industrial operations as a use by right (with no public input or consideration of compatibility with adjacent residential parcels). The county code details the uses by right in the I-3 Heavy Industrial zone:
