These holes are in addition to the holes drilled on the Spring Hills Estates before this area was excluded. The new soils logs are attached. Our findings indicate that this addition will support on,site sewer systems. It may be necessary to spot the houses so that the higher areas are used for waste disposal systems. ' The Creek setback will generally force sewer systems into the higher area. We had problems in drilling to 14 feet on Lot 2 because of the dense gravel strata at about 9 feet deep. We experienced a similar problem along the same elevation on the up stream part of the original subdivision. When we used a hack hoe to excavate those original holes we found very large cobbles and boulders which.rejected our drilling efforts. I believe .this lot can best be developed using a shallow bed or 5 feet wide drainfield. The soils encountered, should not cause foundation problems if the houses are kept toward the higher grounds and away from the creek. If shallow ground water is encountered a foundation drain should be used to keep the crawl space dry. As this is an environmentally sensitive area, the potential buyers should be alerted to our recc~mendations. If you have any ~estions, please let me know.
