A representative from Terracon observed the exterior perimeter drainage system at the referenced
address within the Richard's Lake Subdivision on November 20, 2002, as, requested. At the time of
our site visit, a 4-inch diameter, perforated PVC pipe had been placed around the exterior perimeter
of the basement foundation and was observed to exhibit positive gravity flow toward a sump pit
located in the lower level/basement portion of the residence. Washed gravel was observed below
and above 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 drainage system was constructed in general accordance with the plans
and specifications for the project.
