This area is underlain by expansive soil and Rock Unit RU-302, which consists of over- consolidated high-liquid-limit clay. As a result, the foundation of the strucrure to be built onLotl , , should be designed for highly expansive material. 00 Lots 2 and 3, structures can be placed within - Design Area 3. DA-2 includes the lower-sloping northern and eastern portions of the site, and is underlain by RU- 101, a fme-grained dark gray igneous rock ("basalt"), which is decomposed to depths varying. between 5 and 10 feet. ' DA-3 includes the western and central portions of the site and is underlain by RU-101. In this design area, partly decomposed to nearly fresh state fractured in-place rock is located at shallow depth, potentially requiring larger equipment or hydraulic hammers for deeper excavations. ' No evidence of slope movement was noted on the site, and there is no indication that the proposed development will result in slope stability is~ues, as long as grading recommendations in this report are followed. ' '. Rocky Road Subdivision, Springfield Geotechnical/Soils Assessment, GeoScience. Inc. 8-6-03 11 :. INTRODUCTION This report presents the results of a geotechnical assessment to determine soil and ;ock cOllditions at a proposed subdivision located northeast and east of the current north end of S 47th Street off Jasper Road (Figure 1 ).' The assessment was conducted for:Mi. David Nichols; FE, of Pacific West Engineering. A total of five test pits had been excavated in August of 2002 under direction of Mr. Nichols, and.copies of color photos of these test pets were available for review. The site was re- visited with Mr. Nichols on June 18, 2003,and the older test pit sites were re-examined for evidence of the materials encountered at that time. Based on. these observations, the site appeared to be underlain by two rock units with significantly different characteristics. The distribution of the two units appeared to be well-defmed by the site topography, with the higher and steeper portions, underlain by, competent fme-grained igneous rock ("basalt") and the low-lying portion in the northwest comer underlain by completely decomposed state pyroclastic or contact metamorphic rock. However, additional explorationwas required todeliheate the 'boundary between the two rock units in the west-northwest part of the site. GEOLOGY AND SOILS (Published Information) The geologic map included in Ground Water in ihe Eugene-Springfield Area, Southern Willamette Vally, Oregon (USGS Water Supply Paper 2018, 1973) indicates that the entire site is underlain by , the Tertiary Little Butte V o1canics, which are also known as the Post-Eugene Volcanics in this area According to the ,Water Resources Paper, the Little Butte Volcanics consist of a sequence of , predominantly dacitic and andesitic flows and tuffs and olivine basalt flows with some scoriaceaous ' , material. ' The Soil Survey of Lane County Area, Oregon (USDA Soil Conservation Service, 1987) indicates that the northern portions of the site are underlain by Hazelair silty clay loam, whereas the southern two thirds of the area are ,underlain by Nelda silty clay loam. The Hazelair soil is classified according to the Unified Soil Classification System as a CL soil (upper 15 inches) over a CH soil to 3 feet, with weathered rock below 36 inches. The Nelda soil is classified as an ML soil in the, upper 10 inches over a CL or GC soil; with weathered rock reported at a depth of 35 inches. FIEJ)) ~SrIGATION Methods , The site was originally visited with Mr. Nichols on June 18, 2003. At that time, the material backfilled into the previous test pit locations was observed. The site was re-visited on J~ly 31,2003 and two test pits were excavated using a rubber-tired 4-wheel drive Case 580 backhoe with a 2-foot toothed bucket. Soils encountered in the test pits (and backfilled test pits) were classified according to the Unified Soil Classification System using ASTM Method D-2488 (Visual-Manual Procedure). Distances from known landmarks to the test pits were determined using a Wheel-a- Tape device.

The test 'pits excavated on August 21, 2002, under supervision of Mr. Nichols were designed, primarily to determine excavation conditions at the site. Copies of photos of the test pits are included in Appendix A. Assessment of the soil/rock materials in these pits was conducted by GeoScience primarily based on the materials still expos~d in the backfilled test pits and also based on color photos provided by Mr. Nichols. In addition, on August4, 2003 hand auger holes were, advanced in the area immediately surrounding TH-1, between TH-1 and TH-2, and at TH-2. Hand auger logs are included in Appendix B. 2003 Test Pits , ' On July 31, 2003, two additional test pits were excavated alorig the existing driveway. The main , , focus of this exploration was to more closely define the location of the contact between the two major rock units at this site. Testpit logs are included in Appendix B and photos in Appendix C. Results . Soil Units , .. , ., Three soil units were identified at the site, which were designated SU-B, SU-C, and SU-D for purposes of this report. SU-B is present approximately in the area outlined as Nekia soil on the Soil , Survey and SU-C.is presellt in the area outlined as Hazelair soil., SU~D is presentbeneathSU-B/C in the northwest portion of the site. , 'SU-B consists of dark brown to brown. clayey or silty sand with angular stained-state (STS) to Visually Fresh State (VFS) igneous rock fragments (see RU-IOI, below). Rock fragment content varies from-70 to 80,% by volume, the fragments are angular, and range in size from a: few inches to four feet in diameter. The fmer~grained matrix is estimated to consist of75 % fine- to medium- grained, sand arid 25 % fines. The matrix has low dry strength, m~dhlIn toughness, and slow dilatancy. As a result, the matrix is classified as a silty SAND (SM) according to the USCS' and the , fines are probably either MH or CL. The soil appears to be partly matrix-supported and partly clast- supported and ranged 'in thickness from 2 to 4 feet. At the time of test pit excavation, SU-A was dry and below the plastic limit (BPL). The unit is interpreted as a top-soil/colluvial deposit derived from weathering ofRU-IOI on steeper slopes. SU-C consists of dark brown silty sand (70 S, 30 F) with igneous rock fragments. The rock fragment content is lower than inSU-B, ranging from 5 to 20 %. In addition, rock fragments are smaller, ranging in size from 2 to 8 inches. SU-C has low dry strength, low toughness, and rapid dilatancy. ''As a result, SU-C is classified as a silty SAND (SM) according to th~ USCS. SU-C was 'approximately 1.5 to 225 feet thick in the hand auger holes, and was dry and BPL at the time of the site visit. The unit is interpreted as a top-soil/colluvial deposit derived from weathering ofRU-1 0 1 on lower slopes. Rocky Road Subdivision, Springfield . Geotechnical/Soils Assessment, GeoScience, Inc. 8-6-03 2 --.., -'--'-."." -,- ......:.-.. .' ~ ... SU-D consists of gi-ay to light gray sandy clay. TheestiImited gradation is 30 llIo medium-grained sand and 70 % fmes. The unit has very high dry strength; high toughness and no dilatap.cy. As a . result it is classified as a sandy fat CLAY (CH). SU-D wasO.S feet thick inHAH-ID, a:f1d was not encountered in HAH-3. The unit is interpreted as a colluvial deposit derived fi:om weathering of RU-302. Rock Units Two rock units were identified. Rock unit RU-I0l is present beneath the eastern, central, and southwestern portion of the site. RU-302 is present beneath the low-sloping area in the northwest comer of the site.. In visually fresh state (VFS), RU-IOI consists of a. dark gray very fine-grained igneous rock ("basalt"). It was not determined if the unit is intrusive or extrusive. RU~IOI is the source of the igneous rock fragments in SU-B and -C. The depth of weathering of the unit is dependent on ' location. At most locations~ the unit is either completely decomposed or partlY decomposed to depths of five feet or more. Completely decomposed state (CDS) RU-l 0 1 i~ light brown to tan and " remolds with finger pressure to a sandy silt, which is APL when moist. The resulting "soil" has low to medium dry strength, low touglmess, and rapid dilatancy. Partly decomposed state (PDS) RU-l 01 is tan to light gray with rust-brown spots and contains more than 50 % material which cannot be ' remolded with fmger pressure. The depth to partly decomposed RU-l 0 1 appears to be variable from "approximately 2 to 5 feet. The miniinum depths to PDS RU-IOl,appear to be present along the steeper slope in the southwestern portion of the site. The unconfined compressive strength (UCS) of CDS RU-I01 was measured in TP-2, using a pocket penetrometer. The DCS of the material exceeded the range of the instrument (9,000 pst). Rock Unit RU-302 underlies the northwestern part of the site. The unit is present only in completely decomposed state (CDS). In "unweathered" state, the unit consists of a maroon to brick-red to whitish-tan over-consolidated clay, which decrepitates rapidly upon exposure to moisture. In the , presence of mo{sture, the unit can be completely remolded to fines which have very high dry strength, high toughness and no dilatancy. Where re-weathered, the unit is rust brown, but retains its other characteristics. The unit is interpreted"as either a contact-metamorphic zone at the base of the RU-l 01, or a pyro-clastic rock unit which was deeply weathered shortly after deposition, and then consolidated bi burial' under several thousand feet of rock which has subsequently been removed by erosion. ' Rocky Road Subdivision, Springfield Geotechnical/Soils Assessment, GeoScience, Inc, 8-6-03 3 DISCUSSION Based on the observations and subsurface exploratlon;.the site can be divided into three design areas, , which are based on soil/rock unit distributio~ and slope. These areas .are shovm on Figure 3. Design area DA-1 is located in the northwest portion of the site, including Lot 1 and parts of Lots 2 and 3. This area is characterized by the presence ofSU-B/C over SU-D and RU-302. Of these units, SU-D and RU-302 are probably highly expansive. Based on experience with similar or identical rock units in the Eugene/Springfield metro area, only the near~surface portions of RU-302 are subject to ' seasonal moisture changes because swelled portions isolate the deeper portions from water' infiltration. The unit is hard when dry and in-place but decrepitates rapidly upon exposure to moisture and loses significant strength. The swell pressures developed during this hydration process exceed typical residential bearing pressures, and result in distress to structures due to differential up- lift. This issue has been successfully mitigated by deep foundation designs consisting of drilled piers and above-grade concrete beams. It may also be possible to mitigate the condition by flooding of the building pad to expand the foundation material and construction of post-tensioned slabs. 'In the Rocky Road Subdivision, only the northwestern comer of the site is affected and only one lot (L6t 1) is situated such .that the residence will need to be co~structed within DA-l.. Seasonal shallow perched groundwater is expected in DA-1 within SU-B/C. Therefore, it is recommended to install up-slope and side-slope cut-off dIains into SU-D around the residence on Lot 1. For road construction in this area, it is recommended to place geo-fabric on the native sub grade to prevent, mixing of the overlying road base with softened SU-D,or RU-101 during the wet season. Shallow groundwater may be present seasonally, perched on PDS RU-IOl. Therefore, it is , recommended to install foundation drains on the up- and side-slope sides of residence inDA-2. Such drains should extend into native material at least 6 inches below the base of the adjacent footing, should be lined with filter fabric and backfilled with open drain rock after placement of a perforated rigid pipe with glued joints. DA-3 includes all or parts of Lots 2 through 8. DA-3 is characterized by the presence ofSU-B over RU-I 0 I. Deep excavations for foundations and/or underground utilities in this area may require use of a large trackhoe, and, in some cases, a hydraulic hammer. Excavations are likely to produce large fragments ofVFS RU-101 (from both SU-B and in-place PDS-VFS'RU-IOI). }toc!':y Road Subdivision, Springfield .

None of the design'areas show evidence of previous slope movement. 'The steeper portions o(the , subdivision are underlain by competent in-place RU-I01. Slopes in the area undeilaiii.~t shallow depths by RU-302 are sufficiently gentle to preclude deep-seated slope movement. - Due to the content of expansive clay minerals it is not recommended to use excavated SU-D or RU- 302 as structural fill. SU-B, -C,and CDS RU-I0l can be used as structural fill after removal of oversize material, which may not be cost-effective. Pennanent cut banks in SU-B and SU-C should be sloped at no steeper than 2H : IV. In CDS to PDS RU-I0l such cut banks can be sloped at 1.75 : 1. Stained-state (STS) to VFS RU-I0l can be sloped near-vertical, although rock falls cJ.ueto freeze-thaw may be expected after the bank has been in place for several years. CONCLUSIONS, Surficial observations' and subsurface exploration of the proposed Rocky Road subdivision in Springfield indicates that the site is underlain by two rock units with widely differing characteristics. The northwest portion of the site is underlain in the shallow subsurface by RU-302,which originated either as a contact metamorphic at the lower margin of, RU-l 01, or is the product of weathering and subsequent over-consolidation of a pyroclastic deposit. RU-302 is maroon to brick-red to whitish tan and consists entirely of high..,Jiquid-limit clay which, in-place, is over-consolidated. When , weathered, the color is rust-brown. In-place material decrepitates rapidly in the presence of water, , softening to a material whith can be remolded to APL with finger pressure. Once completely hydrated and remolded, the material has very high dry strength, high toughness, and no dilatancy. As'a result, it.is likely that RU,.302 is expansive. , , RU-IO 1 consists (in fresh state) of a dark gray very fme-grained igneous rock. In' CDS, the unit is tan and can be completdy remolded (when moist) to a san<;iy (very fine-grained) silt with low dry strength, low toughness, and rapid dilatancy. These characteristics are not consistent with expansive soil. 1bree soil units were identified at the site. The steeper slopes in thewestern portion are underlain by SU-B, which consists of angular fragments ofRU-10l up to 4 feet or more in diameter, in a dark brown to brown matrix of silty sand (SM), with low dry strength, low toughness and slow dilatancy. Rock fragments constitute from 70 to 80 % (by volume) of SU-B. Rock fragment frequency decreases with distance from the steeper slope, and much fewer rock fragments ~e present in the lower-sloping northeastern and eastern portion of the site. The soil in that vicinity contains between 10 to 20 % rock fragments in a dark ,brown silty sand matrix equivalent to that ofSU-B. This soil, was designated SU-C. In the northwest portion of the site, SU-D is found under SU-B/C, overlying RU-302. SU-D consists ofa gray to light gray fat clay (CH), which, appears to have been derived from weathering of RU-302. No evidence of previous slope movement was noted at the site.' , Rock')' Road Subdivision, Springfield GeotechnicallSoils Assessment, GeoScience, Inc. 8-6-03 5 RECOMMENDATIONS The proposed subdivision can be divided into, three design areas based, on geotechnical considerations. The pertinent recommendations for each design area are summ~zed below: DA-l Foundations It is recommended to design foundations for structures in DA-I to rrutigate the effects of the presence of highly exp~sive RU-302 and SU-D. This can be achieved by construction of deep foundations (e.g.. drilled piers) and above-grade concrete beams. Piers should be installed to at least five feet below the top of in-place RU-302, and, in that case, may be designed for allowable bearing pressures of 9,000 psf. If slabs are to be constructed for garages, it is recoInmended to either construct a slab:-on-joist system or to avoid tying slabs to the perimeter foundation. Alternatively, foundation maybe constructed by inundation of the building pad and placement of a post-tensioned slab foundation. In the latter case, it is possible that the slabs may be somewhat out of level after , differential shrinking or swelling. For road construction it is recommended to place Geo-fabric . (woven, e.g. Amoco 2002) on the native subgrade to prevent mixing of softened SU-D or RU-302 with the road base material. Wet weather construction in DA-I may present significant challenges due to loss of strength of the native subgrade when exposed to moisture. ' Excavation and Grading All materials within DA-I can be excavated by conventional means. Permanent cut slopes in SU-D through RU-302 should be retained. Fill slopes in this area should not exceed four feet in depth without further engineering design and should be sloped at no more than 3H : "1 V. Slope Stability No slope stability issues are anticipated if recommendations regarding grading are followed. Use of Materials It is not recommended to use any materials excavated from DA-I as structural fill. Whereas SU-B/C may be suited for use as structural fill, the thickness of these units and close association with underlying expansive SU-D and RU-302 makes it difficult to completely separate the units. Drainage Areas around strUctures should be sloped to.drain away from the buildings. It is recommended to install a shallow cut-off drain around the up-slope and side-slope perimeter of structures in this area in order to intercept groundwater which is probably seasonally perched on SU-D and/or RU-302. Rocky Road Subdivision, Springfield Geotechnical/Soils Assessment, GeoScience. Inc. 8-6-03 6 DA-2 Foundations '. Foundations in DA-2 can be constructed as conventional spread-footings on CDS to PDS or less weatheredRU-101. If foundations are to be constructed on CDS RU-101, the bearing capacity should be verified, by a qualified professional prior to placement of rock or concrete forms. Excavation and Grading Excavation is anticipated to be possible with conventional methods to depths up to 5 feet or deeper. Cut banks in CDS/PDS RU-1 0 1 will be temporarily stable at near-vertical angles unless construction is conducted during wet weather. Permanent cut banks in CDS/PDS RU-IOl should be'sloped at no steeper than 2: 1 and the tops should be rounded to preclude sloughing of SU-BIC. Fill slopes should be constructed no steeper than 2 : 1. ' Slope Stability There is no evidence of slope stability issues in this area. , Use of Materials . . . . SU-C and CDS-PDS RU~101 may be utilized as structural fill provided over-size materiaI is removed prior to compaction. Verification of compaction may be difficult unless pr90f-rolling is used, or if sufficient Proctor testing is conducted to provide for mixing-curves of the materials. Drainage Because shallow groundwater is expected to be perched on PDS RU-101 seasonally, it is recommended to installfoundation drainage at structures within DA-2. These drains should ~onsist ofa trenchexcavated into native,CDS/PDS RU-101 on theup- and side-slope sides of structures to , a depth of at least 6 inches below adjacent base of footing grade. The trenches should ,be sloped to drain, lined with filter fabric, and backfilled wi~ drain rock after placement of a perforated rigid pipe with glued joints. Drain rock should be extended to within 12 inches of the surface, and covered with filter fabric priotto placement of other material (top soil, crushed rock, etc.). Rocky Road Subdivision, Springfield Geotechnical/Soils Assessment, GeoScience, Inc. 8-6-03 7 ' '. DA-3 Foundations Foundations in DA-3 can be placed on CDS to VFS RU-l 0 1 and can consist ofconventional spread footings. Due to potential differential settlement, foundations should not be placed partly on SU-B ' and partly on in-place RU-IOl. For foundations placed on CDS RU-IOl bearing capacity should be verified by a qualified professional prior to placement of a leveling course 'or concrete forms. Excavation and Grading Excavation within DA-3 may require use of a large excavator or a hydra~ic hammer. However, with the information presently available it is not possible to identify areas or depths where such measures may become necessary. ' , Permanent cut banks in CDS/PDS RU-I01 should be sloped at no steeper than 1.75H : IV. Cut .banks in VFS RU-IOI may be sloped near-vertical but, in that case, maybe subjectto rock falls due to freeze-thaw after several years. Fill slopes in this area should not exceed 2 : 1. Slope Stability There is no evidence of previous slope movement in this area. The area is underlain at shallow depth by competent RU-IOI and no deep-seated failures are anticipated. Drainage Seeps may occur from fractures in PDS to.VFS RU-lOl during the wet season. Therefore, it is recommended to install foundation drainage at structures with daylight basements in DA-3.

February 19,2004 Mr. David Nichols, PE ,Pacific West Engineering 3610 Goodpasture Loop , Eugene OR 97401 ' RE: ' GEOTECHNICAL MEETING ITEMS RELATING TO ROCKY ROAD, SUBDIVISION Dear Mr. Nichols: , " , ' I am 'writing this letter per the discussion on February 17, 2004 at the meeting regarding the proposed, Rocky Road subdivision. Comments had been received from City of Springfield staff regarding the' ,subdivision application documents, and the meeting had been called to clarify these comments and determine the responses required to satisfy the requirements.. Specifically, City staffnoted that the original GeoScience geotechnical report (dated August 6, 2003) , ' ' did not contain recoinmendations regarding construction of public improvements (e.g. streets arid . public utilities) fot Design Areas 2 and 3. These areas are underlain by RU-l 01 (as described in the , original report)at depths varying from a few inches to 2 feet. RU-10l is present in completely decomposed state (CDS) to partly decomposed state (PDS) to depths of 1 0 feet or greater. The rock , unit is overlain by SU-C a brov.n cIay~y sand (SC) "\\ith low dIy strength, low toughness and slow dilatancy. Neither SU-C, nor CDS RU-I0l have characteristics consistent with the presence of expansive clay. Therefore, no special measures are required for road construction in this area. The , , uppermost, organic-rich portion ofSU-C should be removed prior to placement offill. During wet weather construction, SU-C and the upper po.rtions' of CDS RU-l 0 l' should be protected from softening under traffic loads by placement of at least six inches of inches of base rock. . Excavation for underground utilities will not present aproblem in Design Area 2, because ,all units can be excavated to the required depths using conventional means. In Design Area 3, road base rock can be placed on CDS to 't7isually fresh s:tate(VFS) RU-! 01. Grading in SU-B may result in ripping up of larger rock fragments, and the resulting holes will need to be filled.' However, no other special measures are required for road,construction in this area. Public utility trenches (e.g. sanitary and stonn sewers) in DA-3 may encounter areas where a large , trackhoe or hydraulic hammer is required for excavation. Limiting trench depths to the minimum required will minimize this possibility. ' ~ 1"\ 0_....

Specifically, the three lots at the northwest corner of the subdivision (Lots 7, 1, and 2) are bisected by the boundary between DA-l and DA-3. Of these, the corner lot (Lot 1) is located mostly withinDA-l, and will require a foundation designed to mitigate for the presence of expansive soil and RU-302. On Lots 2 and 7; it is possible to place the building envelope within either DA-l or'DA-3,or over the boundary. It is recommended to leave the determination of where to place the house up to the future owner or builder. If the residence is proposed to be placed entirely or partly , within DA-l it is recommended to require a foundation which mitigates the expansive material in the subsurface (e.g. drilled pier foundation with above-grade beams)~ lfthe residence is proposed. . to be constructed entirely within DA-3, it is recommended to require inspection of the foundation excavation by a qualified geotechnical professional prior to placement of a leveling course or foundation forms. In this manner, it is possible to verify the presence of RU-l 01 as the foundation subgrade. If you have any questions regarding this matter, please do not hesitate to contact me at 607-5700.
