Soggy soil dampens Ninth Street extension project

Although Monday proved to be a typically warm, late June day, excess water was on the minds of officials at Colorado Northwestern Community Col­lege.

Added moisture on the site where the college plans to build a new campus west of Craig could add more costs to preparing the site for construction.

As the developer of the 100-acre parcel, CNCC is required to extend Ninth Street to the westernmost edge of the property, which was estimated to cost about $692,000.

Last week, however, crews discovered the soil beneath the road site was unstable, wrote Dan Giroux, a Diversified Consulting Solutions, Inc. consultant, in an e-mail to college officials last Tuesday.

The culprit: water in the soil.

“They (crews) knew would be some (water) over there,” said Gene Bilodeau, CNCC Craig campus dean, during the college’s monthly board meeting Monday night.

“In some of the initial testing (crews) did, they thought it was just spring runoff, or they thought it was isolated to certain pockets.”

However, further studies showed that additional actions would be necessary to shore up the soaked soil.

Twin Peaks Utilities and Infrastructure, a Lafayette-based company, has completed other infrastructure projects on the site under its $2.7 million contract with The Memorial Hospital.

The hospital is planning to build a new facility on the 100-acre parcel.

The hospital may have the same problem, Bilodeau said, adding that the hospital hasn’t encountered it yet because “they haven’t dug to the depth we have for Ninth Street.”

In a letter to Twin Peaks officials, a geotechnical specialist working with DCS recommended the firms’ crews remove at least 18 inches of the wet soil in the roadway.

The firm also suggested laying fabric where the proposed road would be built to prevent further destabilization.

As of Monday evening, the total cost of these projects still was unknown.

Representatives from DCS, the college’s owner’s representative, recently met with city officials to discuss the issue, Bilodeau said.

John Sattler, DCS president, said he could not yet estimate how much it would cost.

However, he added, fixing the problem likely would result in a change order, or supplemental funding.
