Re: Exterior Perimeter Drain Observation,
Ridgewood Hills 3`d Filing
709 Keenesburg Court - Lot 303
Fort Collins, Colorado
Terracon Project No. 20005162
A representative of Terracon observed the perimeter drain at the above referenced address on July
14, 2004, as requested. A four -inch diameter perforated PVC pipe had been placed around the
exterior perimeter of the basement and crawl -space foundations with an impervious PVC membrane
beneath the drainage system. The drainage pipe appeared to exhibit positive drainage toward the
sump pit located within the basement area. We also observed 1 to 1-1/2-inch washed gravel placed
above and below the pipe and drainage filter fabric above the gravel. The waterproof dampening
was also observed and in our opinion was uniformly applied to the exterior foundations.
In our opinion the exterior perimeter drain was constructed in general accordance with the plans and
specifications for this project.
Sincerely,
TERRACON Reviewed By'
