3/10/2017 | A traffic impact study (TIS) was not required as part of the Weld County USR application, but a traffic narrative was submitted. Per the narrative, the operator is committed to using a local water source or temporary pipeline to deliver water to location for completion operations in an effort to reduce truck traffic. Although the initial haul route approved by Weld County would utilize Cherry Avenue (County Road 43) and 24th Street, this haul route has since been eliminated.
The Board of County Commissioners added a condition of approval to the Use by Special Review that stated that Extraction shall attempt to obtain an access permit through CDOT for an access onto Business Highway 34. As of 9/15/2016, the CDOT Access Permit for access onto Business Highway 34 was approved. The haul route will now be that all traffic will be on Business Highway 34 and turn onto the access to the Vetting pad and facility from the highway. No truck traffic will be on Cherry Creek Ave nor will pass the Bella Romero School. The updated haul route will be provided to all operator personnel and contractors working on location.
Extraction agreed to an additional condition of approval through the USR that truck traffic will avoid school pick up and drop hours. |
