' Our work was completed in general accordance with the authorized subcontract dated December I, 2011. The site location is indicated on attached Figure 1. The existing Jack Park occupies the north side of Krueger Creek. Recent property acquisition will , expand the park to the south side of the creek. The Jack Park Improvements project involves the aforementioned bridge as well as associated pathways and other landscape improvements. A recently ' completed Tualatin Valley Fire and Rescue (TVF&R) facility borders the south side of the side,just upslope from the proposed bridge. Explorations for this fire station project were presented in a 2007 geotechnical report by Carlson Geotechnical and were used to supplement the current study. The , following report provides our geotechnical evaluation of the bridge site, including our findings, conclusions, and geotechnical engineering design recommendations. SITE AND PROJECT DESCRIPTION The proposed pedestrian bridge will span Krueger Creek and its associated wetlands. We understand a prefabricated bridge will be placed with a single span on the order of 100 feet in length. Bridge width will be approximately 6 feet. We understand axial loads at each abutment will be on the order of 40 kips. Tension and lateral forces are anticipated to be very minimal. The approximate proposed bridge alignment is shown on the attached Site Plan, Figure 2. Krueger Creek flows northeast within a well-defined, approximately 6-to 8-foot wide incised channel. The base of the creek is about 4 vertical feet from the top of the bank, and at the time of our ' reconnaissance(December 12), water depth was 6 to 12 inches. Above the bank is a broad floodplain with elevation generally between 211 and 212 feet. The floodplain is approximately 90 feet in width with about two-thirds of this width on the north side of the creek. The floodplain is bordered on the ' south by an approximately 2.5H:1 V (horizontal:vertical) slope and on the north by an approximately 5H:I V slope. The bridge foundations will be built into these slopes. Jack Park Bridge, Tigard, OR GEOTECHNICS LLC DOCUMENT REVIEW GEOLOGIC AND SOILS MAPPING ' The site geology is mapped in the Oregon Department of Geology and Mineral Industries (DOGAMI) Bulletin 60 (Schlicker and Deacon, 1967). The map shows the site area underlain by Quaternary-age ' Willamette Silt. These soils are described as unconsolidated beds and lenses of fine sand, silt, and clay. Geologic mapping of the area is also presented in DOGAMI Open File Report 0-90-2 (Madin, 1990). Madin maps site soils as fine grained flood deposits with a thickness of greater than 40 feet. Madin describes these soils as "tine grained sediments deposited by late Quaternary catastrophic floods". Soils at the site are mapped by the United States Natural Resources Conservation Service Soil Survey of Washington County, Oregon(Green, 1982). The soils mapped on site are Delena silt loam, 3 to 12 percent slopes (Unit 16C). Unit 16C soils tend to be silty to clayey, with very slow permeability, and are reported to display slow to medium runoff and slight to moderate erosion hazard. We additionally reviewed Landslide lnventoty Mugs of the Becmerion Quadrangle (Burns et. al, 2011). These recent maps use LIDAR (Light Detection and Ranging) imagery to map landslides throughout the Beaverton Quadrangle. This mapping shows no landslides on the property or within the near vicinity of the site. TVF$R GEOTECHNICAL REPORT We requested and received the geotechnical report prepared for the new fire station bordering the site ' to the south of the proposed bridge (Carlson, 2007). Their exploration program included 3 hollow- stem-auger borings and one Cone Penetrometer sounding(CPT). Maximum boring depth(boring B-1) was 51.5 feet and the depth of CPT-1 was 71 feet. Laboratory testing was performed on samples from boring B-1 and included Atterberg Limits and Percent Fines testing. ' Near surface soils encountered were described as soft to medium stiff sandy silt. Groundwater was encountered at a depth of 12 to 13 feet below ground surface (bgs). We have attached copies of the logs for B-1 and CPT-1 which we selected to supplement our own data. Approximate locations of these explorations are shown on Figure 2. Among the Carlson conclusions was that near surface soft to medium stiff silt soils could support an allowable bearing pressure of 2,000 psf with resulting settlement of less than one inch provided the upper 16 inches is removed and replaced with compacted crushed rock Carlson also evaluated liquefaction and concluded that approximately 3 inches of liquefaction-induced ground surface settlement could result from a Magnitude 7 earthquake having a peak horizontal ground acceleration of 0.33g. ' EXPLORATIONS We completed field explorations at the site on January 4, 2012. Our explorations consisted of two hand auger borings to depths of 11 and 12 feet bgs and two dynamic cone penetrometers (DCP) to depths of 15'/2 and 16'/i feet bgs. The dynamic cone provides an equivalent blow count, or `N-value', ' for estimation of consistency and pile penetration resistance. The explorations were completed at the proposed north and south bridge abutments and the approximate locations are shown on Figure 2. The logs of the explorations are included as Figures Al through A4. Samples .were collected from the File 11-031-1 January 24, 2012 Page 2 of 9 Jack Park Bridge,Tigard, OR GEOTECHNICS LLC , hand-auger borings and returned to our soils laboratory for further examination and testing. The ' results of our laboratory tests are included on the boring logs and on Figure A5. In general, our findings were consistent with the conditions described by the geologic mapping. Soft ' to medium stiff silt and clay were encountered in both borings. On the south side, these materials were very similar silts to those encountered by Carlson Geotechnical on the neighboring site. On the north side, materials were clavier and a hard layer, 2%2 to 3 ft thick, was encountered at about 7'/z ft ' bgs. On the south side, a 4%2-foot layer of soft silt fill was encountered overlying the native silt deposits. Equivalent N-values from the DCP's within the primary footing-influence zone on the south were 4 blows per foot(bpt)and on the north 6 bpf. Shallow groundwater was encountered in both hand auger borings at a depth of about 3'/2 to 4 ft bgs, corresponding to Elevation 211 ft. Based on findings from the Carlson study as v cell as review of well ' logs from the surrounding area, this level likely represents the regional water table. This water table can be expected to vary seasonally and may rise higher than Elevation 211 during prolonged wet periods. Our explorations were performed during the rainy season but not during a prolonged wet ' period. Logs of prior Carlson explorations are included as Figures A6 and A7 and their locations are also ' shown on Figure 2. Carlson's Atterberg Limits test results are shown graphically on Figure A5. CONCLUSIONS AND RECOMMENDATIONS , FOUNDATION SUPPORT Shallow Foundations: The bridge foundations can be supported on spread footings embedded a , minimum of 3 feet below ground surface. Due to the soft soils encountered and based on our settlement estimates, overexcavation of 18 inches will be required to mitigate settlement. Thus, foundation excavations should extend to 4'/2 feet below grade. These excavations should also extend ' outward 6 inches beyond the footing edge on all sides. The slope-side bottom edge of abutment footings should have a minimum horizontal offset of 5 feet from the slope face. Overexcavated soils should be replaced with compacted crushed rock. Crushed rock material and compaction requirements are specified below in the Earthivorkv section of this report. Replacement crushed rock should be underlain by a geotextile separator consisting of a medium strength woven fabric such as Mimfi 50OX or approved equivalent. Foundations as described above should be proportioned for a maximum allowable bearing pressure of ' 1,250 pounds per square foot (psf). This bearing pressure applies to the total of dead and long-term live loads and may be increased by one-third when considering earthquake or wind loads. This is a net bearing pressure. The weight of the footing and overlying backfill can be ignored in calculating ' footing sizes. We expect that spread foundations designed and constructed as recommended will experience ' settlements of less than 1-inch. Differential settlements of up to one-half of the total settlement magnitude can be expected. Lateral loads on footings can be resisted by passive earth pressure on the sides of footings and by ' friction on the bearing surface. We recommend that passive earth pressures be calculated using an equivalent unit weight of 300 pounds per cubic foot(pcf). We recommend using a friction coefficient , File 11-031-1 January 24,2012 Page 3 of 9 ' Jack Park Bridge, Tigard, OR GEOTECHNICS LLC ' of 0.5 between the base of the footing and the compacted crushed rock. The passive earth pressure and friction components may be combined provided that the passive component does not exceed two- thirds of the total. Passive resistance should be reduced by the following factors on the downslope ' side based on slope inclination: • 3H:1 V: 44% ' • 411:1 V: 35% • 511:1 V: 28% ' Helical Anchor Foundations: If the required size and depth of shallow foundations are too great, bridge abutments can alternatively consist of a pile cap supported by helical anchors. Pile caps should ' have a minimum depth of 2 feet bgs and a minimum width oft feet. Based on the anticipated abutment load of approximately 40 kips and foundation length of about 8 feet, a single row of two to four anchors will be possible. Our analyses indicate a required minimum embedment of 15 feet below the base of the pile cap. Multiple helices will be required to resist the anticipated loading. We recommend any of the following helix configurations and allowable loads: ' Helical Anchor Design Recommendations Helix Configuration Allowable Load(kips) Minimum Spacing(ft) 8"/10" 8 2.5 8"110'/12" 14 3.0 ' 10"/12"/14" 20 3.5 We expect that helical anchor foundations designed and constructed as recommended will experience settlements of less than 1-inch. Differential settlements of up to one-half of the total settlement magnitude can be expected. ' Lateral loading should be accommodated by passive resistance as specified above for shallow foundations. Alternatively, battered anchors could be installed to resist lateral loads. For helical anchor supported foundations, we cannot rely on any lateral resistance from friction between the base of the pile cap and the underlying soil. ' Load testing should be performed, with one test at each abutment. Helical anchor installation should be observed by the geotechnical engineer to confirm required levels of torque. Geotechnics LLC should also be retained to review specifications related to anchor installation and testing. ' Slope Stability: We analyzed slope stability using the modeling program Slope/W by Geo-Slope International, Ltd. The abutment foundations will be built into ascending slopes having inclinations of 5H:1 V to 2.5H:1 V (approximately 1 I to 22 degrees from horizontal). Our analyses indicate that slopes in the vicinity of proposed foundations are stable for both static and seismic conditions. Since foundation support will be at or very near the base of the slopes, the proposed improvements will have ' no adverse effect on slope stability. File 11-031-1 January 24, 2012 Page 4 of 9 Jack Park Bridge, Tigard, OR GEOTECHNICS LLC ' Our conclusions regarding stability and passive resistance are based on the assumption that foundation , embedment will be maintained throughout the life of the project. We assume the bridge abutments will not be subject to scour. If the bridge. will be subject to scour, scour protection such as,slope armoring will be specified by others. Evaluation of scour is beyond the scope of our study but, upon ' request we.can provide soil parameters for scour analyses. RETAINING WALLS ' We understand the pedestrian path in the vicinity of abutments may require retaining walls. For low- height walls retaining cul slopes, gravity wails will be the most economically feasible choice. These would include rockery walls or other.gravity systems such as ecology block or Ultrablodk@ systems. ' We recommend such walls be limited in height to 8 feet and be designed with a batter no steeper than 1H:4V. To retain fills on the descending slope;MSE (Mechanically Stabilized Earth) walls will be the ' logical choice with facing usually consisting of concrete modular units such as Keystoneg blocks. UltrablockV systems, can also be designed as MSE walls. Conventional concrete cantilever walls cannot be ruled out, but in this, environment are less desirable due to their rigidity and relative ' sensitivity to soil settlement. Design details ++•ill depend on the wall system selected. For use in wall design, we recommend the , following soil parameters for in-place site soils: • Angle of internal friction, 9:28' • Cohesion, c: 0 ' • Wet unit weight,1,: 115 pcf • Active pressure, equiv. fluid wt.: 40 pcf. ' Note that the above recommendations assume level backfill behind the wall and a drainage system to prevent the buildup of hydrostatic pressures. ' Geotechnics LLC is available to perform design of MSE or gravity retaining walls. If designed by others, Geotechnics should be provided the opportunity to review calculations and dra+vings to verify , that valid assumptions were made relative to material properties and other factors. SEISMIC HAZARDS ' Liquefaction: As noted, Carlson Geotechnical predicted approximately 3 inches of liquefaction induced ground surface settlement from the design earthquake (Magnitude 7 earthquake with peak horizontal ground acceleration of 0.338). The settlement is attributed to non-plastic or low plasticity ' sandy silts below the water table. We concur that this is a reasonable settlement estimate given the available data and this amount of settlement can be extrapolated to the bridge site, whether shallow foundations or helical anchors are used. The bridge should be designed to accommodate 3 inches of ' differential settlement between the two abutments without collapse. In our experience, design to prevent all damage caused by liquefaction-induced settlement of this magnitude is rarely cost effective ' for this size project and where temporary disruption of service(for repairs) is feasible. In our opinion, the cost of mitigating against liquefaction (possibly 50-foot deep driven piles) would far outweigh the cost of required foundation repairs following the earthquake. ' Slope Stability and Lateral Spreading: The potential for seismic slope instability has been addressed above. Based on our seismic limit-equilibrium analyses, the site slopes in the vicinity of the bridge File 11-031-1 January 24, 2012 Page 5 of 9 ' Jack Park Bridge, Tigard,OR GEOTECHNICS LLC ' will remain stable under the design earthquake. Liquefaction-induced lateral spreading occurs on slopes underlain generally by loose sands and shallow groundwater. Based on the silty and clayey materials encountered near surface, and the level of the groundwater table with respect to the free face t (creek bank), we consider the potential for lateral spreading at this site to be minimal to none. Fault Surface Rupture: Faults have not been mapped within the boundaries of the site or adjacent ' properties (USGS, 2006). No indications of the presence of faulting were noted during our field investigation. We consider the possibility of fault rupture and displacement at this site to be remote. ' Ground Shaking: We assume seismic design of bridges will be performed in accordance with the 2009 International Building Code and/or AASHTO I_RFD Bridge Design Specifications. Appropriate levels of ground acceleration and other parameters for the basis of design can be taken from the USGS ' Earthquake Hazards website using a Site Class of D. EARTHWORKS Wet Weather Construction: The silty soils at the site can be expected to become easily disturbed during periods of wet weather or ' when the moisture content of the material is more than a few percentage points above optimum. This will likely be the case in all but mid-summer through early fall. When wet, the on-site soils are susceptible to disturbance and generally will provide inadequate support for construction equipment. ' We recommend earthwork be scheduled for dry summer months, if possible. If earthwork is scheduled for the wet season or significant precipitation occurs during construction, special techniques ' may be needed to minimize disturbance to the subgrade from construction traffic when wet. A temporary working pad constructed of 12 to 24 inches or more of crushed rock over a geotextile fabric might be needed where traffic occurs. Slopes should be protected and stability under wet conditions ' should be verified. Excavation: Site soils within expected excavation depths should consist predominantly of soft to medium stiff silt to clay. It is our opinion that conventional earthmoving equipment in proper working condition should be capable of making necessary general excavations for footings and other earthwork, although low ' impact tracked equipment may be required to minimize site disturbance. The earthwork contractor is responsible to provide equipment and procedures to excavate the site soils described in the exploration logs and text of this report. Dewatering: ' Groundwater is not likely to occur within the depths of expected excavations during the dry season. During the wet season, groundwater seepage is possible. Excavations that extend into saturated soils should be dewatered. If groundwater is encountered, sump pumps placed in the excavations should be sufficient for dewatering the silty and clayey soils. In addition to groundwater seepage, surface water inflow to the excavations during the wet season could be problematic. Provisions for temporary surface water control should be included in the project ' plans and should be installed prior to commencing work. ' File 11-031-1 January 24, 2012 Page 6 of 9 Jack Park Bridge, Tigard, OR GEOTECHNICS LLC Temporary Excavations: ' Excavation sidewalls should stand near-vertical to a depth of at least 4 feet, provided perched or near-surface groundwater seepage does not affect the sidewalls. Excavations made to construct ' footings or other structural elements should be laid back at the surface as necessary to prevent soil from falling into excavations. All excavations should be made in accordance with applicable Occupational Safety and Health Administration(OSHA) and state regulations. Site soils are generally t OSHA Type B. Fill Materials and Compaction: ' Imported structural fill materials will be required as replacement material for foundation overexcavations. Structural fill should consist of clean, durable, crushed angular rock. Such rock ' should be well-graded and have a maximum particle size of 1'/z inches, and less than 5 percent passing the U.S. No. 200 Sieve. The material should be placed and compacted in lifts not exceeding 9 inches in uncompacted thicknesses and to a minimum of 95 percent of maximum dry density, as determined ' by ASTM D1557. Surface Drainage and Erosion Control: Surface runoff can be controlled during construction by careful grading practices. Typically, these ' include the construction of shallow, upgrade perimeter ditches or low earthen berms and the use of temporary sumps to collect runoff and prevent water from damaging exposed subgrades. Also, ' measures should be taken to avoid ponding of surface water during construction. Permanent control of surface water should be incorporated in the final grading design. Adequate , surface gradients and drainage systems should be incorporated into the design such that surface runoff is directed away from structures and into swales or other controlled drainage devices. Some site soils may present a moderate erosion hazard. In our opinion, erosion at the site during construction can be minimized by judicious use of straw bales, silt fences and plastic sheets. The erosion control devices should be in place and remain in place throughout site preparation and ' construction. Maintaining appropriate erosion control is the responsibility of the contractor and should be carried out in accordance with the project plans and specifications and applicable regulations. CONSTRUCTION OBSERVATIONS ' Satisfactory foundation and earthwork performance depends to a large degree on quality of construction. Sufficient monitoring of the contractor's activities is a key part of determining that the , work is completed in accordance with the construction drawings and specifications. Subsurface conditions observed during construction should be compared with those encountered during the exploration program. Recognition of changed conditions often requires experience; therefore, the ' project geotechnical engineer or their representative should visit the site with sufficient frequency to detect whether subsurface conditions change significantly from those anticipated. The geotechnical engineer of record should be retained to evaluate footing excavations and, if helical anchors are used, ' should provide oversight of installation and load testing.
