Whitham Farms Property aka Bloom Development
Fort Collins, Colorado
CTL|T Project Number: FC08020-115 L1
CTL|Thompson, Inc. previously provided a Preliminary Geotechnical
Investigation for the Whitham Farms property in Fort Collins, Colorado. The
investigation was performed under CTL|T Project No. FC08020-115, report dated
January 22, 2018. We were provided with cut/fill plans as well as updated site plans and
were requested to review our report to verify that the recommendations contained within
are still appropriate at this time.
Development plans created by Galloway project No. HFH000022.10 dated
August 17, 2021, Norris Design, project No. SP100, recorded November 7, 2022, and a
cut/fill map provided by a subcontractor at the site were reviewed to prepare this letter.
Currently, the site grading is underway over most of the subdivision. Portions of the
sanitary sewer have been installed below the proposed Greenfields Drive, between
Mulberry Frontage Road and International Boulevard. S torm sewer installation is
underway. Cuts on the order of ½-foot to 6 feet are planned, with most of the cut greater
than ½-foot expected in areas where there are to be detention ponds. Fill on the order
of ½-foot to 7½ feet are planned over much of the site.
The material encountered during excavations at the site, that have been
observed by CTL|Thompson, appeared to be consistent with that found in our borings.
Shallow groundwater and possibly expansive soils were the primary geotechnical
concerns at this site. Groundwater was measured at depths of 7 to 23 feet in our
borings and is assumed to have remained unchanged. The installation of utilities may
result in a change in the groundwater levels. The presence of expansive soils will be
further explored during future investigations at the site. The recommendations
presented in the preliminary investigation report remain valid.
