Despite the shortened Labor Day work week, Washington Gas installed 100 linear feet of gas line. Subsurface conditions changed from the difficult solid rock encountered last week to softer, easier to excavate soils. DDOT and Washington Gas continued to work together this week to adjust the gas line as needed to avoid the maze of existing underground storm drains and utility pipes.
For those who were wondering, the KVT project was not affected by the mineral oil spill that was discovered along Klingle Road NW over the Labor Day weekend. The damaged PEPCO pipe was east of Rock Creek, and contamination was limited to Rock Creek and areas downstream of Klingle Creek. The steep grade of the Klingle Valley also prevents any upflow from Rock Creek. Over the weekend emergency environmental remediation crews installed two temporary dams just east of the project limits in Rock Creek to contain the mineral oil contamination.
