On October 15, 2001, a representative from Terracon observed the foundation excavation for the
above referenced lot within the Waterglen Subdivision in north Fort Collins, Colorado, as requested.
The soil conditions exposed within the foundation area consisted of clayey sand fill material and sandy
lean clay. The soil encountered is similar to that described in our Geotechnical Engineering Report
prepared for the site and dated January 5, 1994 (please refer to our Project No. 20935286). Based on
our observations, it is recommended the structure be supported by a spread footing foundation system
designed in accordance with the recommendations set forth in the report.
At the time of the observation, no bedrock or free groundwater was encountered within 3-feet of the
foundation area. However, based on recommendations set forth in the Geotechnical Engineering
Report, as well as to minimize the potential for surface water infiltration or groundwater fluctuations
from entering the crawl space, it is our opinion a dewatering system should be placed around the lower
level of the structure. The drainage system should be installed and constructed in accordance with the
recommendations set forth in the geotechnical engineering report.
If you have any questions, or require further information, please feel free to contact us at your
convenience.
