Street Springfield, Oregon 97448 RE: 845 So. 67lt1 Street Springfield - Site/Soils Investigation. W.O # 14503-ROR As you requested, a site/soils investigatIon was perfonned on these three adjacent lots on April 11, 2002. Design for the site is as follows: All unsuitable fill, vegetation, and un buildable material have been removed to native grade. The native soil consists of approximately 4 feet of brown clayey loam top soil over 2 feet of expansive clay over a decomposed sandstone/ash. The site is to be excavated thru the clay layer where feasible and if not feasible a minimum of 12 inches of compacted crushed rock Installed with tracked excavation equipment. The crushed rock i$ to be '[hen compacted with either a Vibratory drum or plate compaction equipment. On April 22, 2002, a compaction inspection was preformed after fill placement. The compacted surface of the 1 1h .. minus crushed rock is adequate for a foundation bearing capacity of 1500 psf, which is adequate to support the proposed conventional wood frame residence. The compaction of the gravel surface is greater than 95% of a standard proctor per ASTM 0698-91. Thank you for this opportunity to be of service.
