Interstate 70 r ' t Published maps, e.g. Van Horn (1972'), depict the site as underlain by Upper Pleistocene Louviers Alluvium. Louviers Alluvium typically consists of silty sand with occasional gravel. Subsequent weathering commonly results in alteration of feldspars in these materials to clays. The surficial soils are mapped as underlain by interbedded strata of the upper Cretaceous / lower Tertiary Denver and Arapahoe Formations. In the northwest Denver metropolitan area, the Denver and Arapahoe Formations consist largely of claystones and sandstones interbedded on various scales with local lignite beds. The claystones typically are moderately to highly expansive. Well cemented, resistant sandstones are encountered locally, as well as over - consolidated, but uncemented and friable sandstones.

A total of two (2) test holes were drilled with a truck - mounted, continuous flight auger rig within the proposed platform footprint to evaluate the subsurface conditions as well as to retrieve soil and bedrock samples for laboratory testing and analysis. The test holes were advanced to depths ranging from approximately 35 to 40 feet. Remaining test holes could not be drilled due to unavailable property access. A representative of GROUND directed the subsurface exploration, logged the test holes in the field, and prepared the soil and bedrock samples for transport to our laboratory. In addition, borings from previous studies provided in the project documents were also reviewed, specifically; boring logs S -1 and S -2. These boring logs were provided from a previous study by RockSol and are attached in Appendix D. Samples of the subsurface materials were retrieved with a 2 -inch I.D. California liner sampler. The sampler was driven into the substrata with blows from a 140 -pound hammer falling 30 inches. This procedure is similar to the Standard Penetration Test described by ASTM Method D1586. Penetration resistance values, when properly evaluated, indicate the relative density or consistency of soils. Depths at which the samples were obtained and associated penetration resistance values are shown on the test hole logs. The approximate locations of the test holes are shown in Figures 1, 2 and 3. Logs, explanatory notes, and a legend of the exploratory test holes are presented in Appendix A. LABORATORY TESTING Samples retrieved from our test holes were examined and visually classified in the laboratory by the project engineer. Laboratory testing of soil and bedrock samples obtained from the subject site included standard property tests, such as natural moisture contents, dry unit weights, grain size analyses, and liquid and plastic limits. Swell - consolidation potential, water - soluble sulfate and corrosivity tests were completed on select samples as well. Laboratory tests were performed in general accordance with applicable ASTM and AASHTO protocols. Results of the laboratory testing program are summarized on Tables 1 and 2, and in Appendix B.

These materials were underlain by sands and gravels that extended to depths of approximately 32 to 33 feet below existing grades. These were underlain by claystone bedrock, which extended to the test hole termination depths of approximately 35 to 40 feet below existing grades. Although fill materials were not recognized in GROUND's test holes, they exist on site and were encountered in Rocksol Test Holes S -1 and S -2. The exact extents, limits, and composition of any man -made fill were not determined as part of the scope of work addressed by this study, and should be expected to exist at varying depths and locations across the site. Graphic logs, legend, and location summary of the test holes are included in Appendix A. Sand and Clay was low to medium plastic, fine to coarse grained, very soft or very loose to stiff or medium dense, moist to wet, and pale brown to brown in color. Shallow man -made fill of similar consistency is also likely present near the surface. Sand and Gravel was occasionally clayey, non to low plastic, fine to coarse grained with gravels and cobbles, loose to very dense, moist to wet, and brown to gray to yellow to red to tan to black in color. Claystone Bedrock was highly plastic, fine grained, hard, dry to moist, and blue -gray in color. Groundwater was observed in both test holes at depths of 15 to 16 feet below existing grades at the time of drilling. Groundwater levels can fluctuate, however, in response to annual and longer -term cycles of precipitation, irrigation, surface drainage and land use, and the development and drainage of transient, perched water conditions. Swell- Consolidation Testing of samples of the overburden materials encountered in the project test holes indicated no potential for heave. Consolidation values ranging from 0.3 to 0.9 percent were measured against a 1,000 -psf surcharge pressure. GROUND Job No. 10 -9300 Ground Engineering Consultants, Inc.

The seismic design category for a structure is permitted to be determined in accordance with Section 1613 (2006/2009 IBC) or ASCE 7." Exceptions to this are further noted in Section 1613. Utilizing the USGS's Earthquake Ground Motion Tool v.5.0.9a and site latitude /longitude coordinates of 39.787859 and — 105.133263 (obtained from Google Earth) respectively, the project area is indicated to possess an SDs value of 0.245 and an SDi value of 0.093. In accordance with the 2006/2009 International Building Code, it is GROUND's opinion that Seismic Design Category B would be applicable for seismic foundation design, based on an Occupancy Category of I, II, or III. For Occupancy Category IV, a Seismic Design Category C would be applicable. The Project Structural Engineer should ultimately determine the Seismic Design Category. Compared with other regions of the Western United States, recorded earthquake frequency in the project vicinity is relatively low. Per 2006/2009 IBC, Section 1613.5.2 Site class definitions, `Based on the site soil properties, the site shall be classified as either Site Class A, B, C, D, E or F in accordance with Table 1613.5.2. When the soil properties are not known in sufficient detail to determine the site class, Site Class D shall be used unless the building official or geotechnical data determines that Site Class E or F soil is likely to be present at the site ". Based on the soil conditions encountered in the test holes drilled on the site, our review of applicable geologic maps, as well as our experience within the Project site vicinity, a Site Class D according to the 2006/2009 IBC classification (Table 1613.5.2) is anticipated for seismic foundation design. This parameter was estimated utilizing the above - referenced table as well as extrapolation of data beyond the deepest depth explored. GROUND Job No. 10 -9300 Ground Engineering Consultants, Inc. Page 6 RTD Eagle P3 Project - Gold Line - Ward Road Station (Platform Only) Document No. GL0- GEO -RP01 Rev 1 FINAL (100% submittal) 7/19/11 FOUNDATION SYSTEM OVERVIEW Based on our field and laboratory analysis within the footprint limits of the proposed platform, the materials in the upper 9 to 11 feet consist of relatively loose soils. Shallow foundations placed directly on soils, such as those encountered at the project site, could experience post- construction structural movements as a result of settlement. In order to reduce the potential for post- construction movement, sub - excavation /overexcavation is often used in the Denver area to reduce potential post- construction movements and allow the use of a shallow foundation system. The proposed platform may be founded on a shallow foundation system consisting of spread footings or a reinforced mat foundation bearing on a minimum depth of 5 feet of properly moisture - density treated on -site generated soils and /or approved import fill material. Given that the allowable differential movement between the tracks and the platform is low, the fill prism should be uniform in depth beneath the platform and the rail lines and extend at least 5 feet beyond the foundations of the platform. At the approaches to the platform, the over- excavation and re- compaction zone should be tapered from the 5 -foot depth within 5 feet of the platform a distance of 25 feet to the standard subgrade preparation depth for the track. To reduce differential movements, two (2) layers of geogrid reinforcement should be incorporated within the fill prism below the spread footing foundation and rail areas as described below. Final grading plans were not available at the time this report was prepared. The overexcavation recommendations provided within this report are based on a finish grade elevation of approximately 5466 feet in the platform area. If final finish grade elevation is at a variance from this assumption, GROUND should be contacted to re- evaluate the provided recommendations. STATION PLATFORM / RAIL / BALLAST FOUNDATION SYSTEM The design and construction criteria presented below should be observed for a spread footing foundation system. The construction details should be considered when preparing project documents. The precautions and recommendations provided below will not prevent movement of the footings if the underlying materials are subjected to alternate wetting and drying cycles. However, the recommended measures will tend to GROUND Job No 10 -9300 Ground Engineering Consultants, Inc.

The fill material could be generated from the on- site derived granular overburden soils and /or approved imported granular fill material. All fill should be placed in accordance with the criteria provided in the Project Earthwork section of this report. Excavation and replacement of the fill prism should take place directly beneath the platform footings and rail sub - ballast as well as at least 5 feet beyond the platform foundations. At the approaches to the platform, the over - excavation and re- compaction zone should be tapered from the 5 -foot depth, beneath the footings, within 5 feet of the platform a distance of 25 feet to the standard subgrade preparation depth for the track. The bottom of the excavation prism should be at a uniform elevation. It may be necessary to improve the fill platform base of the overexcavation area (5 to 6 feet below subballast elevation) by densification and /or other means to increase the stability of the overlying backfill zone. The recommendations in the Soft and Wet Subgrade Conditions subsection should be considered, as necessary. 2) Two layers of geogrid (TenCate Mirafi® and /or Tensar(D products or equivalent) should be placed within the fill prism. These layers should be placed at elevations coinciding with 0 feet and 2.5 feet above the bottom of the overexcavation elevation. Geogrid reinforcement is not required in the tapered zones at each platform approach outside the platform area. The subgrade should be leveled prior to the placement of the geogrid. Geogrid placement should be performed according to the manufacturers' recommendations. Geogrid should be overlapped in accordance with manufacturers' recommendations. Geogrid may be disturbed under the wheel loads of heavy construction equipment, especially track type vehicles, therefore no vehicle traffic should be GROUND Job No. 10 -9300 Ground Engineering Consultants, Inc.

The recommended allowable bearing pressure was based on an assumption of drained conditions and a potential total settlement of 1 inch or less. If foundation materials are subjected to an increase /fluctuation in moisture content, the effective bearing capacity will be reduced and greater post- construction movements than those estimated above may result. 4) Footing excavation bottoms may expose loose, organic or otherwise deleterious materials, including debris. Firm materials may become disturbed by the excavation process. All such unsuitable materials should be excavated and replaced with properly compacted fill. 5) In order to reduce differential settlements between footings or along continuous footings, footing loads should be as uniform as possible. Differentially loaded footings will settle differentially. Similarly, differential fill thicknesses beneath footings will result in increased differential settlements. 5) Spread footings should have a minimum footing dimension of 16 or more inches. Actual footing dimensions, however, should be determined by the Structural Engineer, based on the design loads. 6) Footings should be provided with adequate soil cover above their bearing elevation for frost protection. Footings should be placed at a bearing elevation 3 or more feet below the lowest adjacent exterior finish grades. 7) Continuous foundation walls should be reinforced top and bottom to span an unsupported length of at least 10 feet. 8) The lateral resistance of spread footings will be developed as sliding resistance of the footing bottoms on the foundation materials and by passive soil pressure GROUND Job No 10 -9300 Ground Engineering Consultants, Inc. Page 9 RTD Eagle P3 Project — Gold Line — Ward Road Station (Platform Only) Document No. GLO- GEO -RP01 Rev 1 FINAL (100% submittal) 7/19/11 against the sides of the footings. Sliding friction at the bottom of footings may be taken as 0.33 times the vertical dead load. 9) Compacted fill placed against the sides of the footings should be compacted in accordance with the recommendations in the Project Earthwork section of this report. 10) Care should be taken when excavating the foundations to avoid disturbing the supporting materials. Hand excavation or careful backhoe soil removal may be required in excavating the last few inches. 11) Foundation soils may be disturbed or deform excessively under the wheel loads of heavy construction vehicles as the excavations approach footing levels. Construction equipment should be as light as possible to limit development of this condition. The use of track - mounted vehicles is recommended since they exert lower contact pressures. The movement of vehicles over proposed foundation areas should be restricted. 12) All footing areas should be compacted with a vibratory plate compactor prior to placement of concrete. 13) A Geotechnical Engineer should be retained to observe and test (if necessary) footing bearing areas prior to placement of reinforcing steel or concrete. EXTERIOR FLATWORK Exterior flatwork and other hardscaping placed on the soils encountered on -site may experience post- construction movements due to volume change of the subsurface soils. Both vertical and lateral soil movements can be anticipated as the soils experience volume change as the moisture content varies. Distress to rigid hardscaping likely will result. The following measures will help to reduce damages to these improvements. Subgrade under exterior flatwork or other (non building or station platform) site improvements should be excavated and /or processed to a minimum depth of 24 or more inches. The excavated soil should be replaced as properly moisture - conditioned and compacted fill as outlined in the Project Earthwork section of this report. It may be GROUND Job No 10 -9300 Ground Engineering Consultants, Inc. Page 10 RTD Eagle P3 Project - Gold Line - Ward Road Station (Platform Only) Document No. GLO- GEO -RP01 Rev 1 FINAL (100% submittal) 7/19/11 necessary to increase the depth of subgrade preparation in localized areas depending on the conditions encountered. Prior to placement of flatwork, a proof roll should be performed to identify areas that exhibit instability and deflection. The soils in these areas should be removed and replaced with properly compacted fill or stabilized. Flatwork should be provided with effective control joints. Increasing the frequency of joints may improve performance. ACI recommendations should be followed regarding construction and /or control joints. Exterior flatwork should not extend to under any portion a structure where there is less than 2 inches of clearance between the flatwork and any element of the structure. Exterior flatwork in contact with brick, rock facades, or any other element of the structure can cause damage to the structure if the flatwork or building move differentially with respect to each other. As discussed in the Surface Drainage section of this report, proper drainage also should be maintained after completion of the project, and re- established as necessary. Water should not be allowed to pond on or near any of the site improvements. Concrete Scaling: Climatic conditions in the project area including relatively low humidity, large temperature changes and repeated freeze — thaw cycles, make it likely that project sidewalks and other exterior concrete will experience surficial scaling or spalling. The likelihood of concrete scaling can be increased by poor workmanship during construction such as 'over- finishing' the surfaces. In addition, the use of de -icing salts on exterior concrete flatwork, particularly during the first winter after construction, will increase the likelihood of scaling. Even use of de -icing salts on nearby roadways, from where vehicle traffic can transfer them to newly placed concrete, can be sufficient to induce scaling. Typical quality control / quality assurance tests that are performed during construction for concrete strength, air content, etc., do not provide information with regard to the properties and conditions that give rise to scaling. In GROUND's experience the measures below can be beneficial for reducing the likelihood of concrete scaling. It must be understood, however, that because of the GROUND Job No. 10 -9300 Ground Engineering Consultants, Inc. Page 11 RTD Eagle P3 Project — Gold Line — Ward Road Station (Platform Only) Document No. GL0- GEO -RP01 Rev 1 FINAL (100% submittal) 7/19/11 other factors involved, including weather conditions and workmanship, surface damage to concrete can develop, even where all of these measures were followed. 1) Maintaining a maximum water /cement ratio of 0.45 by weight for exterior concrete mixes. 2) Include Type F fly ash in exterior concrete mixes as 20 percent of the cementitious material. 3) Specify a minimum, 28 -day, compressive strength of 4,200 psi for all exterior concrete. 4) Including 'fibermesh' in the concrete mix may be beneficial for reducing surficial scaling. RTD design guidelines require fibermesh in exterior walkways. 5) Cure the concrete effectively at uniform temperature and humidity. This commonly will require fogging, blanketing and /or tenting, depending on the weather conditions. 6) Avoid placement of concrete during cold weather so that it is not exposed to freeze -thaw cycling before it is fully cured. 7) Avoid the use of de -icing salts on given reaches of flatwork through the first winter after construction. We understand that commonly it may not be practical to implement some of these measures for reducing scaling due to safety considerations, project scheduling, etc. In such cases, additional costs for flatwork maintenance or reconstruction should be considered in project budgets. WATER - SOLUBLE SULFATES The concentration of water - soluble sulfates measured in a selected sample obtained from the test holes was 0.02 percent (see Table 2). This concentration of water - soluble sulfates represents a negligible degree of sulfate attack on concrete exposed to these materials. Degrees of attack are based on the scale of 'negligible,' 'moderate,' 'severe' and 'very severe' as described in the "Design and Control of Concrete Mixtures," GROUND Job No. 10 -9300 Ground Engineering Consultants, Inc. Page 12 RTD Eagle P3 Project - Gold Line - Ward Road Station (Platform Only) Document No. GL0- GEO -RP01 Rev 1 FINAL (100% submittal) 7/19/11 published by the Portland Cement Association. Based on these data GROUND, makes no recommendation for use of a special, sulfate- resistant cement in project concrete. SOIL CORROSIVITY The degree of risk for corrosion of metals in soils commonly is considered to be in two categories: corrosion in undisturbed soils and corrosion in disturbed soils. The potential for corrosion in undisturbed soil is generally low, regardless of soil types and conditions, because it is limited by the amount of oxygen that is available to create an electrolytic cell. In disturbed soils, the potential for corrosion typically is higher, but is strongly affected by soil conditions for a variety of reasons but primarily soil chemistry. A corrosivity analysis was performed to provide a general assessment of the potential for corrosion of ferrous metals installed in contact with earth materials at the site, based on the conditions existing at the time of GROUND's evaluation. Soil chemistry and physical property data including pH, oxidation - reduction (redox) potential, sulfides, and moisture content were obtained. Test results are summarized on Table 2. Reduction - Oxidation: testing indicated a red -ox potential of 18 millivolts. A low potential typically creates a more corrosive environment. Sulfide Reactivity: testing indicated a result of "positive" in the soil tested. The presence of sulfides in the alignment soils suggests a more corrosive environment. Soil Resistivity: In order to assess the "worst case" for mitigation planning, samples of materials retrieved from the test holes were tested for resistivity in the laboratory, after being saturated with water, rather than in the field. Resistivity also varies inversely with temperature. Therefore, the laboratory measurement was made at a controlled temperature. Measurement of electrical resistivity indicated a value of approximately 3,120 ohm - centimeters in a selected sample of retrieved soil. The following table presents the relationship between resistivity and a qualitative corrosivity rating': 2 ASM International, 2003, Corrosion: Fundamentals, Testing and Protection, ASM Handbook, Volume 13A.

In the pH range above 8.5, soils are generally high in dissolved salts, yielding a low soil resistivity Testing indicated a pH value of approximately 7.3. The American Water Works Association (AWWA) has developed a point system scale used to predict corrosivity. The scale is intended for protection of ductile iron pipe but is valuable for project steel selection. When the scale equals 10 points or higher, protective measures for ductile iron pipe are recommended. The AWWA scale is presented below. The soil characteristics refer to the conditions at and above pipe installation depth. 3 American Water Works Association ANSI /AWWA C105/A21.5 -05 Standard.

Based on the values obtained for the soil parameters, the overburden soils appear to comprise a moderately corrosive environment for metals. If additional information or recommendations are needed regarding soil corrosivity, GROUND recommends contacting the American Water Works Association or a Corrosion Engineer. It should be noted, however, that changes to the site conditions GROUND Job No. 10 -9300 Ground Engineering Consultants, Inc. Page 15 RTD Eagle P3 Project — Gold Line — Ward Road Station (Platform Only) Document No. GL0- GEO -RP01 Rev 1 FINAL (100% submittal) 7/19/11 during construction, such as the import of other soils, or the intended or unintended introduction of off -site water, may alter corrosion potentials significantly. PROJECT EARTHWORK The following information is provided for private (RTD station) improvements; public roadways or utilities should be constructed in accordance with applicable municipal / agency standards. General Considerations: Site grading should be performed as early as possible in the construction sequence to allow settlement of fills and surcharged ground to be realized to the extent practical prior to subsequent construction. Prior to earthwork construction, existing structures. vegetation and other deleterious materials should be removed and disposed of off -site. Relic underground utilities should be abandoned in accordance with applicable regulations, removed as necessary, and properly capped. Where newly proposed structures will be constructed within the limits of the demolition of existing structures, care should be taken ensure that all remaining foundation elements and associated structures are entirely removed and a properly placed fill of uniform depth is placed beneath the proposed structure. Topsoil present on -site should not be incorporated into ordinary fills. Instead, topsoil should be stockpiled during initial grading operations for placement in areas to be landscaped or for other approved uses. Existing Fill Soils: Existing fill soils may be present on -site. Although some fill soils may be suitable for replacement as backfill, many may not. In any case, the Geotechnical Engineer should observe the excavated fill materials and provide recommendations for its suitability for reuse. Use of Existing Native Soils: Overburden soils that are free of trash, organic material, construction debris, and other deleterious materials are suitable, in general, for placement as compacted fill. Organic materials should not be incorporated into project fills. On site granular materials are suitable for use in the fill prism beneath the platform. GROUND Job No. 10 -9300 Ground Engineering Consultants, Inc. Page 16 RTD Eagle P3 Project - Gold Line - Ward Road Station (Platform Only) Document No. GLO- GEO -RP01 Rev 1 FINAL (100% submittal) 7/19/11 Fragments of rock, cobbles, and inert construction debris (e.g., concrete or asphalt) larger than 3 inches in maximum dimension will require special handling and /or placement to be incorporated into project fills. In general, such materials should be placed as deeply as possible in the project fills. The Geotechnical Engineer should be consulted regarding appropriate recommendations for usage of such materials on a case -by -case basis when such materials have been identified during earthwork. Standard recommendations that will be generally applicable can be found in Section 203 of the current CDOT Standard Specifications for Road and Bridge Construction. Imported Fill Materials: If it is necessary to import material to the site, the imported soils should be free of organic material, and other deleterious materials. Imported material should consist of soils that have less than 70 percent passing the No. 200 Sieve and should have a plasticity index of less than 15. Representative samples of the materials proposed for import should be tested and approved by the Geotechnical Engineer prior to transport to the site. Fill Platform Preparation: Prior to filling, the top 8 to 12 inches of in -place materials on which fill soils will be placed should be scarified, moisture conditioned and properly compacted in accordance with the recommendations below to provide a uniform base for fill placement. If over - excavation is to be performed, then these recommendations for subgrade preparation are for the subgrade below the bottom of the recommended over - excavation depth. If surfaces to receive fill expose loose, wet, soft or otherwise deleterious material, additional material should be excavated, or other measures taken to establish a firm platform for filling. The surfaces to receive fill must be effectively stable prior to placement of fill. Fill Placement: Fill materials should be thoroughly mixed to achieve a uniform moisture content, placed in uniform lifts not exceeding 8 inches in loose thickness, and properly compacted. Soils that classify as A -1, A -3 A -2 -4 or A -2 -5 in accordance with the AASHTO classification system (granular materials) should be compacted to 95 or more percent of the maximum modified Proctor dry density at moisture contents within 2 percent of optimum moisture content as determined by ASTM D1557, or 100 or more percent of GROUND Job No. 10 -9300 Ground Engineering Consultants, Inc. Page 17 RTD Eagle P3 Project — Gold Line — Ward Road Station (Platform Only) Document No. GL0- GEO -RP01 Rev 1 FINAL (100% submittal) 7/19/11 the maximum standard Proctor dry density at moisture contents within 2 percent of optimum moisture as determined by ASTM D698. Soils that classify as A -2 -6, A -2 -7, A -4, and A -6 through A -7 should be compacted to 95 or more percent of the maximum standard Proctor density at moisture contents from 1 percent below to 3 percent above the optimum moisture content as determined by ASTM D698. Where these soil types are approved for use beneath building, platform, or other foundation elements (excluding flatwork, pavements, curbs), the minimum compaction level should be increased to 98 percent of the maximum standard Proctor density as determined by ASTM D698. No fill materials should be placed, worked, or rolled while they are frozen, thawing, or during poor /inclement weather conditions that adversely affect the placement and compaction effort. Care should be taken with regard to achieving and maintaining proper moisture contents during placement and compaction. Materials that are not properly moisture conditioned may exhibit significant pumping, rutting, and deflection at moisture contents near optimum and above, particularly for silty soils. Settlements: Settlements will occur in filled ground, typically on the order of 1 to 2 percent of the fill depth. If fill placement is performed properly and is tightly controlled, in GROUND's experience the majority of that settlement will typically take place during earthwork construction, provided the contractor achieves the compaction levels recommended herein. The remaining potential settlements likely will take several months or longer to be realized. Cut and Filled Slopes: Permanent site slopes supported by on -site soils up to 10 feet in height may be constructed no steeper than 2.5 : 1 (horizontal : vertical). Minor raveling or surficial sloughing should be anticipated on slopes cut at this angle until vegetation is well re- established. Surface drainage should be designed to direct water away from slope faces. Soft and Wet Subgrade Conditions: The following recommendations should be considered where soft, wet, and unstable subgrade conditions are encountered: GROUND Job No. 10 -9300 Ground Engineering Consultants, Inc.

In areas where apparently stable conditions are found, the subgrade should be proof - rolled or evaluated by a Geotechnical Engineer. b. Pockets of weak or pumping soils or fill should be excavated to a depth of 2 or more feet, as necessary, below culvert bottom and to at least 2 feet beyond its lateral limits. The excavated soil should be replaced with open graded material such as 1 -inch crushed rock up to foundation grade. A geotextile separator fabric should be placed between the crushed rock and native soils. The use of recycled concrete aggregate may be a cost effective alternative in this application. C. In cases where placement of coarse aggregate fill does not result in stable conditions, it will be necessary to place a woven geotextile, Mirafi` HP370 or equivalent fabric placed below the coarse aggregate fill. d. The surface of the subgrade should be leveled prior to geosynthetic reinforcement placement. Very weak or pumping soils should be excavated and replaced with granular fill or road base for best performance. The geosynthetic reinforcement should be placed directly on the prepared subgrade. Placement should be performed according to manufacturer's recommendations. e. Rolls should be overlapped according to the manufacturers' recommendations. f. Geosythetic reinforcement will be disturbed under the wheel loads of heavy construction vehicles, especially track type vehicles, therefore no vehicle traffic should be allowed over the geosynthetic reinforcement until 8 or more inches of soil has been placed over. Fill materials should be thoroughly mixed to achieve a uniform moisture content, placed in uniform lifts not exceeding 8 inches in loose thickness, and properly compacted. (For very weak subgrades, an 18- to 24 -inch "pioneer" or 'first" lift may be required to stabilize the subgrade.) GROUND Job No. 10 -9300 Ground Engineering Consultants, Inc. Page 19 RTD Eagle P3 Project - Gold Line - Ward Road Station (Platform Only) Document No. GL0- GEO -RP01 Rev 1 FINAL (100% submittal) 7/19/11 EXCAVATION CONSIDERATIONS The test holes for the subsurface exploration were excavated to the depths indicated by means of truck - mounted, continuous flight auger drilling equipment. Based on assumed relatively shallow excavations, we anticipate no significant excavation difficulties in the majority of the site with conventional heavy -duty excavation equipment in good working condition. We recommend that temporary, un- shored excavation slopes up to 10 feet in height be cut no steeper than 1.5 : 1 (horizontal : vertical) in the site soils in the absence of seepage. Sloughing on the slope faces should be anticipated at this angle. Local conditions encountered during construction, such as groundwater seepage and loose sand, will require flatter slopes. Stockpiling of materials should not be permitted closer to the tops of temporary slopes than 5 feet or a distance equal to the depth of the excavation, which ever is greater. Should site constraints prohibit the use of the recommended temporary slope angles, temporary shoring should be used. The shoring should be designed to resist the lateral earth pressure exerted by building, traffic, equipment, and stockpiles. GROUND can provide shoring design upon request. Groundwater was encountered in the test holes within the depths explored below existing grades at the time of drilling. However, based on the likely depths of earthwork construction, groundwater is not anticipated to be a factor for shallow earthworks during construction of this project. If seepage or groundwater is encountered in shallow project excavations, the Geotechnical Engineer should evaluate the conditions and provided additional recommendations, as appropriate. Good surface drainage should be provided around temporary excavation slopes to direct surface runoff away from the slope faces. A properly designed drainage swale should be provided at the top of the excavations. In no case should water be allowed to pond at the site. Slopes should also be protected against erosion. Erosion along the slopes will result in sloughing and could lead to a slope failure. GROUND Job No. 10 -9300 Ground Engineering Consultants, Inc. Page 20 RTD Eagle P3 Project - Gold Line - Ward Road Station (Platform Only) Document No. GL0- GEO -RP01 Rev 1 FINAL (100% submittal) 7/19/11 Excavations in which personnel will be working must comply with all OSHA Standards and Regulations. The Contractor's "responsible person" should evaluate the soil exposed in the excavations as part of the Contractor's safety procedures. UTILITY PIPE INSTALLATION AND BACKFILLING Pipe Support: The bearing capacity of the site soils appeared adequate, in general, for support of the proposed utility lines. The pipe + water are less dense than the soils which will be displaced for installation. Therefore, GROUND anticipates no significant pipe settlements in these materials where properly bedded. Excavation bottoms may expose soft, loose or otherwise deleterious materials, including debris. Firm materials may be disturbed by the excavation process. All such unsuitable materials should be excavated and replaced with properly compacted fill. Areas allowed to pond water will require excavation and replacement with properly compacted fill. The contractor should take particular care to ensure adequate support near pipe joints which are less tolerant of extensional strains. Where thrust blocks are needed, they may be designed for an allowable passive soil pressure of 310 psf per foot of embedment to a maximum of 3,100 psf. Sliding friction at the bottom of thrust blocks may be taken as 0.33 times the vertical dead load. Trench Backfilling: Some settlement of compacted soil trench backfill materials should be anticipated, even where all the backfill is placed and compacted correctly. Typical settlements are on the order of 1 to 2 percent of fill thickness. However, the need to compact to the lowest portion of the backfill must be balanced against the need to protect the pipe from damage from the compaction process. Some thickness of backfill may need to be placed at compaction levels lower than recommended or specified (or smaller compaction equipment used together with thinner lifts) to avoid damaging the pipe. Protecting the pipe in this manner can result in somewhat greater surface settlements. Therefore, although other alternatives may be available, the following options are presented for consideration: Controlled Low Strength Material: Because of these limitations, backfilling the entire depth of the trench (both bedding and common backfill zones) with 'controlled low strength material" (CLSM), i.e., a lean, sand - cement slurry, "flowable fill," or similar GROUND Job No. 10 -9300 Ground Engineering Consultants, Inc. Page 21 RTD Eagle P3 Project — Gold Line — Ward Road Station (Platform Only) Document No. GL0- GEO -RP01 Rev 1 FINAL (100% submittal) 7/19/11 material along all trench alignment reaches with low tolerances for surface settlements will provide the most positive means of limiting post- construction settlements in trench backfill materials. If utilized, we recommend that CLSM used as pipe bedding and trench backfill exhibit a 28 -day unconfined compressive strength between 50 to 200 psi so that re- excavation is not unusually difficult. Placement of the CLSM in several lifts or other measures likely will be necessary to avoid `floating' the pipe. Measures also should be taken to maintain pipe alignment during CLSM placement. Compacted Soil Backfillinq: Where compacted soil backfilling is employed, we anticipate that the on -site soils excavated from trenches will be suitable, in general, for use as common trench backfill within the above - described limitations. Backfill soils should be free of vegetation, organic debris and other deleterious materials. Fragments of rock, cobbles, and inert construction debris (e.g., concrete or asphalt) coarser than 3 inches in maximum dimension should not be incorporated into trench backfills. If it is necessary to import material for use as backfill, the imported soils should be free of vegetation, organic debris, and other deleterious materials. Representative samples of the materials proposed for import should be tested and approved prior to transport to the site. Soils placed for compaction as trench backfill should be conditioned to a relatively uniform moisture content, placed and compacted in accordance with the recommendations in the Project Earthwork section of this report. Again, care must be taken to avoid damage to the pipe while achieving recommended compaction levels in the lower portions of the trench. Pipe Bedding: Pipe bedding materials, placement and compaction should meet the specifications of the pipe manufacturer and applicable municipal standards. Bedding should be brought up uniformly on both sides of the pipe to reduce differential loadings. As discussed above, the use of CLSM or similar material in lieu of granular bedding and compacted soil backfill where the tolerance for surface settlement is low should be considered. (Placement of CLSM as bedding to at least 12 inches above the pipe can GROUND Job No 10 -9300 Ground Engineering Consultants, Inc. Page 22 RTD Eagle P3 Project - Gold Line - Ward Road Station (Platform Only) Document No. GLO- GEO -RP01 Rev 1 FINAL (100% submittal) 7/19/11 protect the pipe and assist construction of a well- compacted conventional backfill, although possibly at an increased cost relative to the use of conventional bedding.) If a granular bedding material is specified, GROUND recommends that with regard to potential migration of fines into the pipe bedding, design and installation follow ASTM D2321. If the granular bedding does not meet filter criteria for the enclosing soils, then non -woven filter fabric (e.g., MiraWi 140N, or the equivalent) should be placed around the bedding to reduce migration of fines into the bedding which can result in severe, local surface settlements. Where this protection is not provided, settlements can develop /continue several months or years after completion of the project. In addition, clay or concrete cut -off walls should be installed to interrupt the granular bedding section to reduce the rates and volumes of water transmitted along the sewer alignment which can contribute to migration of fines. If granular bedding is specified, the contractor should not anticipate that significant volumes of on -site soils will be suitable for that use. Materials proposed for use as pipe bedding should be tested by a geotechnical engineer for suitability prior to use. Imported materials should be tested and approved by a geotechnical engineer prior to transport to the site. SURFACE DRAINAGE The following drainage measures are recommended for design, construction, and should be maintained at all times after the project has been completed: 1) Wetting or drying of the foundation excavations should be avoided during and after construction as well as throughout the improvements' design life of the improvements. Permitting increases /variations in moisture to the adjacent or supporting soils may result in a decrease in bearing capacity and an increase in volume change of the underlying soils and /or differential movement. 2) Positive surface drainage measures should be provided and maintained to reduce water infiltration into foundation soils. The ground surface surrounding the exterior of each structure should be sloped to drain away from the foundation in all directions. We recommend a minimum slope of 12 inches in the first 10 feet in the areas not covered with pavement or concrete slabs, or a minimum 3 GROUND Job No. 10 -9300 Ground Engineering Consultants, Inc. Page 23 RTD Eagle P3 Project — Gold Line — Ward Road Station (Platform Only) Document No. GL0- GEO -RP01 Rev 1 FINAL (100% submittal) 7/19/11 percent in the first 10 feet in the areas covered with pavement or concrete slabs. Reducing the slopes to comply with ADA requirements will be necessary but may result in an increased potential for moisture infiltration and subsequent volume change of the underling soils. In no case should water be allowed to pond near or adjacent to foundation elements. However, if positive surface drainage is implemented and maintained directing moisture away from the structures, lesser slopes can be utilized. 3) Where the final site configuration includes graded or retained slopes descending toward the structures or flatwork, interceptor drains may be necessary between the structure and the slope. In addition, where irrigation is applied on or above slopes, drainage improvements commonly are needed near the toe -of -slope to prevent on -going or recurrent wet conditions. The need for edge and interceptor drains should be reviewed once site grades and landscaping plans are developed. 4) Water should not be permitted to pond adjacent to or on sidewalks, hardscaping, or other improvements as well as utility trench alignments, which are likely to be adversely affected by moisture - volume changes in the underlying soils or flow of infiltrating water. 5) Roof /Canopy downspouts and drains should discharge well beyond the perimeters of the structure foundations, or be provided with positive conveyance off -site for collected waters. 6) Vegetation that may require watering should ideally be located 10 or more feet from structure perimeters, flatwork, or other site improvements. As a minimum, vegetation requiring irrigation should not be located within 10 -feet of structure perimeters. However, we understand that local municipalities often require landscaping within 10 feet of structure perimeters. As a result, we recommend that landscape irrigation should be kept to a minimum and surface drainage should be directed away from structure perimeters. Ideally, drip irrigation and water -tight planters should be utilized. In no case should water be introduced into the foundation elements. Irrigation sprinkler heads should be deployed so that applied water is not introduced near or into foundation /subgrade soils. The GROUND Job No. 10 -9300 Ground Engineering Consultants, Inc. Page 24 RTD Eagle P3 Project — Gold Line — Ward Road Station (Platform Only) Document No, GLO- GEO -RP01 Rev 1 FINAL (100% submittal) 7/19111 risk of post- construction movement increases should landscape irrigation be located within 10 feet of structure perimeters 7) Use of drip irrigation systems can be beneficial for reducing over -spray beyond planters. Drip irrigation can also be beneficial for reducing the amounts of water introduced to foundation /subgrade soils, but only if the total volumes of applied water are controlled with regard to limiting that introduction. Controlling rates of moisture increase in foundation /subgrade soils should take higher priority than minimizing landscape plant losses. 8) Where plantings are desired within 10 feet of a structure, ideally GROUND recommends that the plants be placed in water -tight planters, constructed either in- ground or above - grade, to reduce moisture infiltration in the surrounding subgrade soils. Planters should be provided with positive drainage away from structures. 9) Plastic membranes should not be used to cover the ground surface adjacent to foundation walls. Perforated "weed barrier' membranes that allow ready evaporation from the underlying soils may be used.

It may not contain sufficient information for other parties or other purposes. The geotechnical conclusions and recommendations in this report relied upon subsurface exploration at a limited number of exploration points, as shown in Figures 1 through 3 as well as the means and methods described herein. Subsurface conditions were interpolated between and extrapolated beyond these locations. It is not possible to guarantee the subsurface conditions are as indicated in this report. Actual conditions exposed during construction may differ from those encountered during site exploration. If during construction, surface, soil. bedrock, or groundwater conditions appear to be at variance with those described herein, the Geotechnical Engineer should be advised, so that re- evaluation of the recommendations may be made in a timely manner.

Performance of the proposed structures and pavement will depend on implementation of the recommendations in this report and on proper maintenance after construction is completed. Because water is a significant cause of volume change in soils and rock, allowing moisture infiltration may result in movements, some of which will exceed estimates provided herein. Todd Roberts.
