Howes • P.O. Box 503 Fort Collins, Colorado 80521-0503 (970)484-0359 Fax:(970) 484-0454 A representative of Terracon observed the perimeter drain construction at the referenced site on July 22, 2002, as requested. A four -inch diameter perforated PVC pipe underlain by a PVC impervious liner material had been placed around the exterior perimeter of the basement foundation. The drainage pipe appeared to exhibit positive drainage toward the sump pump located within the basement area. We also observed 3/-inch washed gravel placed above and below the pipe and drainage filter fabric placed above the gravel. The waterproof dampening of the foundation system was also observed and in our opinion was completed in general accordance with standard residential practices. In our opinion the exterior perimeter drain was constructed in general accordance with the plans and specifications for this project. Sincerely, TERRACON yo)v, Gary L. Wilson, E.I.T.
