Bobcat Drill

We’re getting our ducks in row to begin construction of the Burke-Gilman Trail connection at Hartmann this summer. As we get ready for permitting and final design of this project, our geo-technical engineers will drill three soil samples during the week of March 25. We expect this work will take about two days to complete.

On the first day, the crew will take a sample of the soil in the area adjacent to the Burke-Gilman trail. They will access the location via the trail accompanied by two flaggers to alert walkers and cyclists. On the second day, workers will drill two core samples on the parking lot of the Hartmann building. The equipment will be unloaded at 7 a.m.; work will begin at 8 a.m. and finish by 4 p.m. on both days.

The Bobcat utility vehicle used for this work is relatively light and equipped with rubber treads so there should be no damage to the trail surface. Our engineers are also coordinating with arborists to make sure that the drilling locations will not compromise the roots of the Sequoia tree(s). We expect minimal noise (about 75 decibels) from the Bobcat’s engine, and some periodic hammering noise (between 90 and 100 decibels).

Improving access to the Burke-Gilman Trail is a key goal of our Livable Streets Initiative, if you have any comments or concerns, please contact Todd Johnson at
