Subject: Engineering Evaluation of Buried Data Lines
Introduction
A segment of underground communications and data lines run along the frontage of the Hitch Rack Ranch
and are considered existing structures located within 200 feet of the proposed Hitch Rack Ranch Quarry
permit boundary. These locations along Highway 115 are shown on Figure 1. This engineering evaluation
discusses the structure locations and components before evaluating potential impacts quarry development
could have on the structure. It also presents what measures will be taken to minimize these impacts.
Structure Description
Communications and data lines transmit information and are frequently buried along roadways. In this
instance they are buried along the west side of Highway 115 corridor and marked with delineator posts
notifying the public of a buried utility. There are no buried utility lines in the mining area. Work activities
in the vicinity of these buried utility lines will only occur during construction of the access road.
Potential Impacts and Mitigation
Potential Problem: Construction of the access road could damage the buried lines.
Solution: Construction crews routinely work around utilities and have standard operating procedures for
not impacting or damaging the utility lines. As part of these procedures, Transit Mix will call 811 for an
underground utility locate prior to construction to identify the exact location of the buried lines. The
standard operating procedures also typically include signage on each side of the utility to remind operators
of the hazard and require digging alongside of the utility and then extending the excavation laterally or using
water or air jetting excavation techniques. Transit Mix will ensure that these practices are followed when
working near utility lines. Transit Mix will also work with CenturyLink to ensure that the construction
occurs without incident.
Conclusions
Buried communications and data lines exist within 200 feet ofthe proposed Hitch Rack Ranch Quarry permit
boundary. These utilities are only located along Highway 115 and are not present in the proposed mining
areas. Construction around buried lines is extremely common, and the construction crews will follow
