Martin Marietta is evaluating potential aggregates sales yard and asphalt/ready-mix concrete production sites along railroads in Weld County that meet specific transportation and production criteria. One of the locations under consideration is the “Highway 34” site, located at 27486 Weld County Road 13, one-half mile south of Highway 34 in Weld County. The proposed site is made up of two parcels, totaling 133 acres. The western parcel is currently developed and permitted in Weld County to allow for the operation of a construction business. The eastern parcel is currently agricultural farmland.
Martin Marietta submitted a Use by Special Review (USR) application for the Highway 34 Development in April. We developed a site plan that addresses the concerns of our neighbors.
Community members who participated in the neighborhood meeting in January 2015 will notice that the site plan presented in the neighborhood meeting is different that the site plan submitted to the County in the USR application. After the public involvement meetings, various studies were conducted to evaluate potential impacts to surrounding properties and land uses. These reports are included in the USR application and cover the topics of noise, traffic, health, air emissions, visibility, wildlife, water supply, and engineering review of existing irrigation ditches.
Findings in these studies led us to incorporate mitigation techniques into the USR site plan submitted to the County.
Some of these mitigation techniques include:
- Constructing earthen berms within the Highway 34 Development site, to address noise and visual concerns,
- Operational sound controls in the asphalt plant activities,
- Changes in the tank installation at the asphalt plant to address odor concerns,
- White noise back up alarms for noise mitigation, and
- Installing primary and secondary access is off Weld County Rd 13 to address employee safety.
Please review the USR application for the full inventory of mitigation strategies and to review the supplemental reports.
