We arrived at the request of the client to observe receptor soil conditions for the site infiltration facilities. A summary of
our observations and recommendations is presented below.
Northeast Infiltration Facility
Upon arrival, we observed the contractor completing excavation of the NE facility. We observed that the SE trench had
beencompletely backfilled, with silty sand visible at the surface and inlet #3 had been installed. The approximate extent
of the excavation is shown on the attached site plan. The excavation was about 5 feet wide and we were told by the
contractor that the bottom of the trench was at approximately 20 feet elevation.
The 6 inch layer of low permeability silt observed in our exploratory test pit had been excavated and removed in general
accordance with our recommendations. The floor of the trench generally consisted of brown fine sand with some silt,
which is consistent with the design receptor soils and project plans and is adequate for the infiltration facility subgrade,
in our opinion.
