placing this signal light back in operation.
By virtue of this letter, the City of Coppell is requesting that a check in the amount of $5,032.18 be

RE: Signal Damage at Heartz Rd. & Sandy Lake Rd.
On 10/7/99 the traffic signal at Heartz & Sandy Lake received a voltage' surge at an estimated
voltage of 25KV. This surge, by witness accounts, was initiated by a piece of construction
equipment working on the sub-grade of the Sandy Lake Rd. Project. This piece of equipment
bumped into a TU transmission line pole that caused the power wires to sag onto our traffic signal
span wire. The short resulted in the destruction of many electronic components, and damage or
destruction of other components, all of which are listed below.
