Eugene, OR 97401 RE: 6357 Femhill Ct. - Site/Soils/Compaction Investigation- Job #264-05 As you requested, a site soils investigation was performed at the above address, Site visits were performed on July 19,20,21,2005 to supervise the excavation of the site for the proposed construction. All unsuitable fills, organics and other unsuitable material has been removed to suitable grade, The excavation required the removal ofunsuitabJe landslide and expansive soils to a depth of approximately 6'.8' on the south portion of the site, to suitable decomposed sandstone. The ' sandstone has a Unified Classification ofML-SM and a plasticity index of less than 20. This soil is not considered expansive (after Holtz 1959). Imported compacted crushed 3" open was placed and compacted in lifts of 6'~_8" at the base of the excavation to within 24" of the desired footing elevation for the placement of the stepped foundation walls. 1 W' minus crushed rock was placed at the top 12" to 24" of the excavated site placed and compacted in 6"-8" lifts. A compaction inspection on the gravel fill was performed on 07/25/05. The compacted surface of the I W' minus crushed rock is adequate for the proposed foundation and has a minimum bearing capacity of 1500 psf, The compaction of the gravel surface is greater than 95% of a standard proctor per ASTM D698. Perforated drainlines were placed at the Jow point of the excavation, as directed by this office, and are to be tied to the approved outlet for this subdivision's storm water system. Drainlines as specified on the site plan at the back of the lot are not feasible, due to the possible damage to existing vegetation root system for vegetation that is to remain, The drain line has been installed at the edge and base oft1~e engineered fill in open rock at the back of the structure excavation and is to be tied to the approved outlet for storm water, This has been placed in addition to the perimeter footing drains that are to be installed at the back of the structure as per plan. '", Jul 28 05 03:52p Walter Custom Homes 541-683-3373 p.8 It is recommended that the back patio is to be installed as a concrete slab that will be sloped to provide that the runoffwi1l be directed to the back of the slab drainage systems as described above. A pervious paver system for the slab is not recommended, as the footing drains are to the back of the patio, and surface water from the patio would be allowed to build up against the house foundation, which may cause damage to 'the structure foundation in this area. This report is limited to the site soils investigation related to soils and fill in regard to soil conditions at the excavated structure site at the above address only. Thank you for this opportunity to be of service, If you have questions regarding this report, . contact me at 868-0667. ' Sincerely, Pamela S. Hillstrom, P.E.
