(gjkoch@acewater.com) Re: Subsurface Exploration Report Proposed City of Fort Collins’ - Poudre River Whitewater Park and Vine Drive Roadway Improvements Fort Collins, Colorado EC Project No. 1132044 Mr. Koch: Enclosed, herewith, are the results of the geotechnical subsurface exploration completed by Earth Engineering Consultants, LLC (EEC) personnel for the proposed City of Fort Collins’ Poudre River Whitewater Park project planned for construction north of the existing Colorado State University’s Engines and Energy Conservation Laboratory (EECL) facility, and south of Vine Drive in north Fort Collins, Colorado. As we understand, this project involves the design and construction of a new pedestrian bridge structure spanning the Poudre River, a retaining wall along the Poudre River Trail north of the CSU-EECL facility and south of the Poudre River, a storm sewer junction box, various meandering concrete trails, and widening/improvements to Vine Drive to accommodate the planned development as depicted on the enclosed Figure 1 – Test Boring Location Diagram. An existing Google Earth image diagram is also included as Figure 2, which depicts the current site condition for comparison purposes. This study was completed in general accordance with our proposal dated July 2, 2015, (revised from May 10, 2013). The southern portion of the planned development on the north side of the CSU-EECL facility and south of the Poudre River is known to be a former landfill, with fill and landfill materials extending to the native sand and gravel strata. Clearance was provided by the City of Fort Collins to allow EEC access to the proposed boring locations on the south side of the Poudre River, and a “soil-spotter,” as part of the potential environmental related concerns under the “Soil Characterization Management Plan” (SCMP) was not required during the geotechnical subsurface exploration drilling operations. Landfill debris was noted in Boring Nos. 1 and 2; however was not observed in Boring Nos. 3 through 8 north of the Poudre River. Addendum 1 - 8468 CM/GC for Poudre River Whitewater Park Page 7 of 441 Earth Engineering Consultants, LLC City of Fort Collins – Poudre River Whitewater Park Fort Collins, Colorado EEC Project No. 1132044 December 8, 2016 Page 2 In summary, the subsurface materials encountered in the two (2) southern borings, (i.e., Boring Nos. 1 and 2) consisted of approximately 12 to 16 feet of existing fill material/landfill and/or construction debris overlying native sand, gravel and intermittent cobbles. The native silty sand with gravel and intermittent cobbles extended to the bedrock formation below. The granular stratum was moist to saturated, and medium dense to dense to very dense with increased depths. The underlying siltstone/sandstone bedrock formation was encountered at an approximate depth of 23 feet below existing site grades in Boring No. 1 and extended to the depths explored, approximately 35 feet. Groundwater was encountered in Boring No. 1 at an approximate depth of 16 feet below site grades. The subsurface materials encountered in the borings north of the Poudre River and south of Vine Drive, (i.e., Boring Nos. 3 through 6) consisted of approximately 1 to 3 feet of apparent fill material, generally classified as silty, clayey sand and/or silty sand with gravel, overlying a native sand, gravel and intermittent cobbles strata. The native silty sand with gravel and intermittent cobbles extended to the bedrock formation below in Boring Nos. 3 and 4 and to the depths explored in Boring Nos. 5 and 6, approximately 10 feet. The granular stratum was moist to saturated, and medium dense to dense to very dense with increased depths. The underlying siltstone/sandstone bedrock formation was encountered at approximate depths of 14-1/2 to 15 feet below existing site grades in Boring Nos. 3 and 4 and extended to the depths explored, approximately 20 to 25 feet. Groundwater was encountered in Boring Nos. 3, 5, and 6 at approximate depths of 3 to 5-1/2 feet below site grades. The borings were backfilled upon completion of the drilling operations; therefore subsequent groundwater measurements were not obtained. The subsurface materials encountered in the pavement related borings along Vine Drive, (i.e., Boring Nos. 7 and 8) consisted of an approximate 7 to 10-inch layer of existing asphaltic concrete/bituminous pavement underlain by approximately 5 inches of existing aggregate base course (ABC) in Boring No. 8. Due to existing utility conflicts in the general location of Boring No. 7, only the existing pavement thickness was evaluated. Boring No. 8 was extended to an approximate depth of 10 feet below site grades and beneath the existing pavement section the subsoils in general consisted of silty sand transitioning to silty sand with gravel with increased depths. The granular stratum was moist to saturated, and medium dense to dense to very dense with increased depths and extended to the depths explored. Groundwater was encountered in Boring No. 8 at an approximate depth of 4-1/2 feet below site grade.

As requested, a total of eight (8) soil borings extending to depths of approximately 10 to 35 feet below present site grades were advanced on the south and north banks the of the Poudre River at the planned pedestrian bridge, retaining wall, and storm sewer junction box structure locations, as well at within the planned on and off-site pavement improvement areas to obtain information on existing subsurface conditions. Individual boring logs and a diagram indicating the planned development and approximate boring locations are included with this report. As we understand, this project involves the design and construction of a new pedestrian bridge structure spanning the Poudre River, a retaining wall along the Poudre River Trail north of the CSU-EECL facility and south of the Poudre River, a storm sewer junction box, various meandering concrete trails, and widening/improvements to Vine Drive to accommodate the planned development as depicted on the enclosed Figure 1 – Test Boring Location Diagram. Based on the information provided to us prior to performing the subsurface exploration, we understand the pedestrian bridge structure was expected to be supported by a drilled pier/caisson foundation system extending into the underlying bedrock formation; while the retaining wall and storm junction box structures would probably be founded on conventional spread footing bearing on approved native subsoils and/or engineered controlled fill material. The southern portion of the planned development on the north side of the CSU-EECL facility and south of the Poudre River is known to be a former landfill, with fill and landfill materials extending to the native sand and gravel strata. Clearance was provided by the City of Fort Collins to allow EEC access to the proposed boring locations on the south side of the Poudre River, and a “soil- spotter,” as part of the potential environmental related concerns under the “Soil Characterization Management Plan” (SCMP), was not required during the geotechnical subsurface exploration drilling operations. Addendum 1 - 8468 CM/GC for Poudre River Whitewater Park Page 10 of 441 Earth Engineering Consultants, LLC EEC Project No. 1132044 December 8, 2016 Page 2 The purpose of this report is to describe the subsurface conditions encountered in the requested borings, analyze and evaluate the test data and provide geotechnical recommendations concerning design and construction of foundations for support of the new structures as well as pavement design and construction recommendations for the planned on-site parking area and proposed widening improvement along Vine Drive. EXPLORATION AND TESTING PROCEDURES To develop subsurface information in the immediate areas of the proposed structures and planned pavement improvement areas, Earth Engineering Consultants, LLC (EEC) personnel advanced a total of eight (8) soil borings at pre-selected locations as determined by the project’s civil engineering consultants, Anderson Consulting Engineers, Inc. The boring locations were established in the field by EEC personnel by estimating angles and distances from identifiable site features. The locations of the borings should be considered accurate only to the degree implied by the methods used to make the field measurements. Site diagrams showing the approximate boring locations are attached with this report. The borings were performed using a truck mounted, CME-75 drill rig equipped with a hydraulic head employed in drilling and sampling operations. The boreholes were advanced using 4-inch nominal diameter solid stem flight and 6-inch nominal inside diameter hollow stem augers, as appropriate. Samples of the subsurface materials encountered were obtained using split barrel and California barrel sampling procedures in general accordance with ASTM Specifications D1586 and D3550, respectively. In the split barrel and California barrel sampling procedures, standard sampling spoons are driven into the ground by means of a 140-pound hammer falling a distance of 30 inches. The number of blows required to advance the split barrel and California barrel samplers is recorded and is used to estimate the in-situ relative density of cohesionless soils and, to a lesser degree of accuracy, the consistency of cohesive soils and hardness of weathered bedrock. In the California barrel sampling procedure, relatively intact samples are recovered in removable brass liners. All samples obtained in the field were sealed and returned to our laboratory for further examination, classification and testing. Addendum 1 - 8468 CM/GC for Poudre River Whitewater Park Page 11 of 441 Earth Engineering Consultants, LLC EEC Project No. 1132044 December 8, 2016 Page 3 Laboratory moisture content tests were completed on each of the recovered samples. Atterberg limits and washed sieve analysis tests were completed on selected samples to evaluate the quantity and plasticity of fines in the subgrade. Swell/consolidation tests were completed on selected samples to evaluate the potential for the subgrade materials to change volume with variation in moisture content and load. In addition, water soluble sulfate (SO4) testing was completed on select overburden and underlying bedrock samples to evaluate potential for sulfate attack on Portland cement concrete. Results of the field borings and laboratory testing are indicated on the attached boring logs and summary sheets. As part of the testing program, all samples were examined in the laboratory and classified in general accordance with the attached General Notes and the Unified Soil Classification System, based on the soil’s texture, plasticity and grain size distribution. The estimated group symbol for the Unified Soil Classification System is indicated on the boring logs and a brief description of that classification system is included with this report. Classification of the bedrock was based on visual and tactual observation of disturbed samples and auger cuttings. Coring and/or petrographic analysis may reveal other rock types. SUBSURFACE CONDITIONS Subsurface Description An EEC field engineer was on-site during drilling to direct the drilling activities and evaluate the subsurface materials encountered. Field descriptions of the materials encountered were based on visual and tactual observation of disturbed samples and auger cuttings. The boring logs included with this report may contain modifications to the field logs based on results of laboratory testing and engineering evaluation. The stratification boundaries indicated on the boring logs represent the approximate locations of changes in soil and bedrock types. In-situ, the transition of materials may be gradual and indistinct. Based on results of field and laboratory evaluation, subsurface conditions can be generalized as follows. In summary, the subsurface materials encountered in the two (2) southern borings, (i.e., Boring Nos. 1 and 2) consisted of approximately 12 to 16 feet of existing fill material/landfill and/or construction debris overlying native sand, gravel and intermittent cobbles. The native silty sand with gravel and intermittent cobbles extended to the bedrock formation below. The granular Addendum 1 - 8468 CM/GC for Poudre River Whitewater Park Page 12 of 441 Earth Engineering Consultants, LLC EEC Project No. 1132044 December 8, 2016 Page 4 stratum was moist to saturated, and medium dense to dense to very dense with increased depths. The underlying siltstone/sandstone bedrock formation was encountered at an approximate depth of 23 feet below existing site grades in Boring No. 1 and extended to the depths explored, approximately 35 feet. The subsurface conditions encountered in the borings north of the Poudre River and south of Vine Drive, (i.e., Boring Nos. 3 through 6) consisted of approximately 1 to 3 feet of apparent fill material, generally classified as silty, clayey sand and/or silty sand with gravel, overlying the native sand, gravel and intermittent cobbles strata. The native silty sand with gravel and intermittent cobbles extended to the bedrock formation below in Boring Nos. 3 and 4 and to the depths explored in Boring Nos. 5 and 6, approximately 10 feet. The granular stratum was moist to saturated, and medium dense to dense to very dense with increased depths. The underlying siltstone/sandstone bedrock formation was encountered at approximate depths of 14-1/2 to 15 feet below existing site grades in Boring Nos. 3 and 4 and extended to the depths explored, approximately 20 to 25 feet. The subsurface materials encountered in the pavement related borings along Vine Drive, (i.e., Boring Nos. 7 and 8) consisted of an approximate 7 to 10 inch layer of existing asphaltic concrete/bituminous pavement underlain by approximately 5 inches of existing aggregate base course (ABC) in Boring No. 8. Due to existing utility conflicts in the general location of Boring No. 7, only the existing pavement thickness was evaluated. Boring No. 8 was extended to an approximate depth of 10 feet below site grades and beneath the existing pavement section, the subsoils in general consisted of silty sand transitioning to silty sand with gravel with increased depths. The granular stratum was moist to saturated, and medium dense to dense to very dense with increased depths and extended to the depths explored. Groundwater Observations Observations were made while drilling and after completion of the borings to detect the presence and depth to hydrostatic groundwater. Groundwater measurements are shown on the upper right- hand corner of the attached boring logs. Groundwater was encountered during drilling operations in Boring Nos. 1, 3, 5, 6, and 8 at depths of approximately 3 to 16 feet below ground surface. Groundwater was not encountered in the remaining borings to maximum depths of exploration. The borings were backfilled upon Addendum 1 - 8468 CM/GC for Poudre River Whitewater Park Page 13 of 441 Earth Engineering Consultants, LLC EEC Project No. 1132044 December 8, 2016 Page 5 completion of the drilling operations; therefore subsequent groundwater measurements were not obtained. Fluctuations in groundwater levels can occur over time depending on variations in hydrologic conditions and other conditions not apparent at the time of this report. Long-term monitoring of water levels in the cased monitoring wells, sealed from the influence of surface water, would be required to more accurately evaluate the depth and fluctuations in groundwater levels. We expect piezometric elevations within the subgrades would follow the water level elevations of the river. ANALYSIS AND RECOMMENDATIONS Swell – Consolidation Test Results The swell-consolidation test is performed to evaluate the swell or consolidation potential of soils to assist in determining foundation and pavement design criteria. In this test, relatively intact samples obtained directly from the California ring barrel sampling device are placed in a laboratory apparatus and inundated with water under a predetermined load. The swell-index is the resulting amount of swell or collapse, expressed as a percent of the sample’s initial thickness, after the inundation period. Samples obtained at or near anticipated foundation bearing intervals are generally pre-loaded and inundated with water at approximately 500 to 1000 pounds per square foot (psf) increments to simulate the overburden pressures; while samples obtained at the approximate 1 or 2-foot intervals are generally pre-loaded and inundated with water at an approximate 150 pounds per square foot (psf) increment to simulate the pavement loading conditions in general accordance with Larimer County Urban Area Street Standards (LCUASS) Pavement Design criteria. After the inundation period additional incremental loads are applied to evaluate consolidation response. For this assessment, we conducted a total of five (5) swell-consolidation tests on subgrade and/or foundation related samples collected during our subsurface exploration. The swell index values for the soil samples tested at the 150-psf, 500-psf and 1,000 psf inundation pressures revealed low swell characteristics on the order of (+) 0.0 to (+) 0.3%. The average swell-index result for the pavement/roadway subsoils analyzed herein revealed swell- index values less than the LCUASS 2% criteria for requiring a swell-mitigation plan. However a fly ash treatment approach could be considered for the pavement improvements as a long-term stabilization/subgrade enhancement approach. Addendum 1 - 8468 CM/GC for Poudre River Whitewater Park Page 14 of 441 Earth Engineering Consultants, LLC EEC Project No. 1132044 December 8, 2016 Page 6 Fly ash treatment, if selected, would involve incorporating Class C fly ash within the upper 12- inches of the pavement subgrade sections prior to construction of the overlying pavement structure. Stabilization would consist of blending 12% by dry weight of Class C fly ash in the top 12 inches of the subgrades. The blended materials should be adjusted in moisture content to slightly dry of standard Proctor optimum moisture content and compacted to at least 95% of the materials maximum dry density as determined in accordance with the standard Proctor procedure. Compaction of the subgrade should be completed within two hours after initial blending of the Class C fly ash. Subgrade stabilization of the proposed on and/or off-site pavement sections should be completed in general accordance with the recommendations presented in the LCUASS Pavement Design Manual – Chapter 22. Hveem Stabilometer (R-Value) One (1) composite sample of subgrade materials from the upper 4 feet below pavement grades was obtained during the field exploration for laboratory Hveem Stabilometer/R-Value, (ASTM Specification D2844) analyses to determine the subgrade strength characteristics of the in-place subgrade materials. A summary of those test results is provided in the table below and graphical results are presented in the Appendix of this report. As presented in the Pavement Design and Construction section of this report, a conservative R-Value of 25 was used to determine the design structural number (SN) for the on and off-site pavement improvements.

Due to the unconsolidated and uncontrolled characteristics of the fill material, in conjunction with the potential environmental Addendum 1 - 8468 CM/GC for Poudre River Whitewater Park Page 15 of 441 Earth Engineering Consultants, LLC EEC Project No. 1132044 December 8, 2016 Page 7 related concerns, the in-situ fill/landfill material should not be used for support of foundations. The consistency and composite of the fill/landfill material is unknown, therefore an estimation of short term and /or long-term settlement cannot be determined or a determination of the material’s lateral earth pressures or stability. The lateral earth pressures presented herein are for approved imported cohesive and/or non-cohesive materials placed and compacted in general accordance with the earthwork recommendations in this report. When more detailed plans for the proposed retaining wall are completed, we should be contacted to provide supplemental recommendations regarding backfill placement. The recommendations contained in this report assume that imported/approved fill material will be required, and will be placed according to the recommendations provided herein. If there are any significant deviations from the assumptions concerning fill placement when the final site plan is developed, the conclusions and recommendations of this report should be reviewed and confirmed/modified as necessary to reflect the final planned site configuration. General Considerations Precautions will be required in the design and construction of the pedestrian bridge and retaining wall structures to address the existing fill material with intermittent landfill debris, the removal/excavation of cobbles at increased depths, and penetration of the underlying well cemented sandstone bedrock lenses. It is anticipated that excavations for the proposed construction can be accomplished with conventional earthmoving equipment. However, if excavations penetrating the well-cemented sandstone bedrock are required, the use of specialized heavy-duty equipment such as a rock hammer or core barrel to achieve final design elevations may be necessary. Consideration should be given to obtaining a unit price for difficult excavation in the contract documents for the project. Site Preparation Based on our understanding of the proposed development, it appears small cuts and/or fills may be necessary to achieve design grades. Prior to completing any cuts, fills and/or site improvements, we recommend all existing surficial vegetation and topsoil be stripped from the site. Once the site is stripped of topsoil and vegetation, we recommend removal of any previously undocumented fill Addendum 1 - 8468 CM/GC for Poudre River Whitewater Park Page 16 of 441 Earth Engineering Consultants, LLC EEC Project No. 1132044 December 8, 2016 Page 8 materials and additional cuts be completed. Following stripping of the site, removal of previously placed fill, and after making all cuts, we recommend the exposed subsoils be scarified to a depth of 9 inches, adjusted in moisture content and compacted to at least 95% of standard Proctor (ASTM D698) maximum dry density. The moisture content of the scarified soils should be adjusted to be within ±2% of optimum moisture content at the time of compaction. Fill soils to develop the pavement/flatwork and site subgrades should consist of approved, low- volume-change materials, which are free from organic matter and debris. It is our opinion the on- site silty, clayey sand subsoils and/or approved equivalent borrow source material could be used as fill in these areas, provided adequate moisture treatment and compaction procedures are followed. We recommend the fill soils be placed in loose lifts not to exceed 9 inches thick and adjusted in moisture content and compacted as recommended for the scarified soils. If the site slightly cohesive silty, clayey sand soils are used as fill material, care will be needed to maintain the recommended moisture content prior to and during construction of overlying improvements. Care should be exercised after preparation of the subgrades to avoid disturbing the subgrade materials. Positive drainage should be developed away from the structures and pavements to void wetting of subgrade materials. Subgrade materials becoming wet subsequent to construction of the site improvements can result in unacceptable performance. As presented on the enclosed boring logs and laboratory test results, low swelling soils are present on this site. This report provides recommendations to help mitigate the effects of soil shrinkage or expansion. Even if these procedures are followed, some movement and at least minor cracking in the structures should be anticipated. The severity of cracking and other cosmetic damage such as uneven exterior flatwork will probably increase if any modification of the site results in excessive wetting or drying of the site soils. Eliminating the risk of movement and cosmetic distress may not be feasible, but it may be possible to further reduce the risk of movement if significantly more expensive measures are used during construction. We would be pleased to discuss other construction alternatives with you upon request. In areas where excavations will extend below existing groundwater table or the perched water surface level, such as utility excavation, placement of cleaner granular fill material would be desirable. Those materials should be placed in lifts and compacted to at least 70% relative density. Addendum 1 - 8468 CM/GC for Poudre River Whitewater Park Page 17 of 441 Earth Engineering Consultants, LLC EEC Project No. 1132044 December 8, 2016 Page 9 Areas of deeper fills may experience settlement from underlying native soils and within the placed fill materials. Settlement on the order of 1-inch or more per each 10 feet of fill depth would be estimated. The rate of settlement will be dependent on the type of fill material placed and construction methods. Granular soils will consolidate essentially immediately upon placement of overlying loads. Cohesive soils will consolidate at a slower rate. Foundation Systems – General Considerations The following foundation systems were evaluated for use on the site:  Pedestrian Bridge Structure – Drilled Piers/Caissons  Retaining Wall and Storm Sewer Junction Box Structures – Conventional Spread Footings Foundation Systems – Drilled Piers/Caissons Based on the type of proposed construction and location of the planned pedestrian bridge structure, as well as the subsurface conditions, (i.e., the unknown fill/landfill debris on the south side of the Poudre River), it is our opinion the proposed bridge could be supported by a grade beam and straight shaft drilled pier/caisson foundation system extending into the underlying sandstone bedrock formation. Particular attention will be required in the construction of drilled piers due to the presence of the known landfill debris/material, the depth of bedrock, and the presence of groundwater and the presence of cobbles in the natural granular strata over the bedrock. The disposal of the landfill debris/material excavated/exposed during the installation of the straight shaft drilled piers, if warranted, is beyond the scope of the report. For axial compression loads, the drilled piers could be designed using a maximum end bearing pressure of 40,000 pounds per square foot (psf), along with a skin-friction of 4,000 psf for the portion of the pier extended into the underlying firm and/or harder/cemented sandstone bedrock formation. Straight shaft piers should be drilled a minimum of 10-feet into competent or harder/cemented sandstone bedrock. To satisfy forces in the horizontal direction, piers may be designed for lateral loads using a modulus of 75 tons per cubic foot (tcf) for the portion of the pier within the native fine to course Addendum 1 - 8468 CM/GC for Poudre River Whitewater Park Page 18 of 441 Earth Engineering Consultants, LLC EEC Project No. 1132044 December 8, 2016 Page 10 granular subsoils, and 400 tcf in bedrock for a pier diameter of 12 inches. Due to the unknown characteristics of landfill zone, this zone should not be relied upon to provide any structural/lateral support in the drilled piers. The coefficient of subgrade reaction for varying pier diameters are as follow and generally conform to the formula of, (kh = 75/D, or 400/D respectively for granular sub-soils and bedrock, in which D=pier diameter): Table II - Coefficient of Subgrade Reaction (tons/ft3) Pier Diameter (inches) Landfill Zone Engineered Fill or Native Granular Subsoils Bedrock 18 N/A 50 267 24 N/A 38 200 30 N/A 30 160 36 N/A 25 133 When the lateral capacity of drilled piers is evaluated by the L-Pile computer programs, we recommend that internally generated load-deformation (P-Y) curves be used. To satisfy forces in the horizontal direction using L-piles computer programs, shafts/piers may be designed using the following lateral load criteria: Table III – L-Pile Design Parameters Parameters Native Granular Soils or Structural Fill Bedrock Unit Weight of Soil (pcf) 130 (1) 125 (1) Average Undrained Shear Strength (psf) 0 5,000 Angle of Internal Friction  (degrees) 35 25 Coefficient of Subgrade Reaction, ks & kc (pci) 800-static 500 – cyclic 2,000 – static 800 - cyclic Strain, 50 (%) (2) --- 0.004 *Notes: 1) Reduce by 62.4 PCF below the water table 2) The 50 values represent the strain corresponding to 50 percent of the maximum principal stress difference. The modulus of subgrade reaction for static (ks) and cyclical (kc) are used by the L- Pile computer programs to generate the slope of the initial portion of the “p-y curves.” Addendum 1 - 8468 CM/GC for Poudre River Whitewater Park Page 19 of 441 Earth Engineering Consultants, LLC EEC Project No. 1132044 December 8, 2016 Page 11 For axial loading, a minimum practical horizontal spacing between piers of at least 3 diameters should be maintained, and adjacent piers should bear at or near the same elevation. The capacity of individual piers must be reduced when considering the effects of group action. Capacity reduction is a function of pier spacing and the number of piers within a group. At one diameter, (essentially piers in contact with each other), the skin friction load reduction factor for each pier should be reduced by 50 percent. End bearing values would not be reduced provided the end-bearing stratum is essentially the same. Piers in-line with the direction of lateral loads should have a minimum spacing of at least 6 pier diameters, from the center to center, based upon the larger diameter pier. Due to the complexity of the project, if a closer pier spacing configuration is required, the modulus of subgrade reaction for the initial and trailing piers should be reduced. The effective modulus of subgrade reaction for the first pier, at a spacing of 3 pier diameters, should be calculated by multiplying the respective Kh, Ks, and Kc values by 0.6, while the trailing piers at a spacing of 3-pier diameters, the effective subgrade modulus would be calculated by multiplying the respective Kh, Ks, and Kc values by 0.40. Linear interpolation can be utilized for spacing between the 3 to 6 diameters as presented herein. As presented by others; “Reductions to the modulus of subgrade reaction can be accomplished in L-Pile by inputting the appropriate modification factors for p-y curves. Reducing the modulus of subgrade reaction in trailing piers will results in greater computed deflections on these piers. In practice, the grade beam can force deflections of all piers to be essentially equal. Load-deflection graphs can be generated for each pier using the appropriate p-y multiplier values. The sum of the pier lateral load resistance at selected deflections can be used to develop a total lateral load versus deflection graph for the system of piers.” For lateral loads perpendicular to the line of piers, a minimum spacing of 3 diameters can be used with no bearing capacity reduction. At one diameter, (essentially piers in contact with each other), the piers can be analyzed as one element. Interpolation can be used for intermediate pier spacing conditions. Drilling caissons to design depth should be possible with conventional heavy-duty single flight power augers equipped with rock teeth on the majority of the site. However, the presence of intermittent cobbles at increased depths and areas of well-cemented sandstone bedrock lenses may Addendum 1 - 8468 CM/GC for Poudre River Whitewater Park Page 20 of 441 Earth Engineering Consultants, LLC EEC Project No. 1132044 December 8, 2016 Page 12 be encountered throughout the site where specialized drilling equipment and/or rock excavating equipment may be required. Excavation penetrating the well-cemented sandstone bedrock may require the use of specialized heavy-duty equipment, together with rock augers and/or core barrels. Consideration should be given to obtaining a unit price for difficult caisson excavation in the contract documents for the project. Due to the known landfill debris within the upper, approximately 12 to 16 feet from near surface grades on the south side of the Poudre River, as well as the depth of granular soils with intermittent cobbles encountered below, and extending to the underlying bedrock formation, maintaining shafts may be difficult without stabilizing measures. Groundwater was also encountered at approximate depths of 5-1/2 to 16 feet below site grades in Boring Nos. 1 and 3, therefore we expect temporary casing will be required to adequately/properly drill and clean the drilled piers/caissons prior to concrete placement. Groundwater should be removed from each pier hole prior to concrete placement. Pier concrete should be placed immediately after completion of drilling and cleaning. A maximum 3-inch depth of groundwater is acceptable in each pier prior to concrete placement. If pier concrete cannot be placed in dry conditions, a tremie should be used for concrete placement. Due to potential sloughing and raveling, foundation concrete quantities may exceed calculated geometric volumes. Pier concrete with slump in the range of 6 to 8 inches is recommended. Casing used for pier construction should be withdrawn in a slow continuous manner maintaining a sufficient head of concrete to prevent infiltration of water or the creation of voids in pier concrete. Foundation excavations should be observed by the geotechnical engineer. A representative of the geotechnical engineer should inspect the bearing surface and pier configuration. If the soil conditions encountered differ from those presented in this report, supplemental recommendations may be required. Foundations – Conventional Type Spread Footings Based on results of field borings and laboratory testing as outlined in this report, it is our opinion the proposed retaining wall and storm sewer junction box structure could be supported on conventional type spread footing foundations bearing on the native granular subsoils or on a zone of engineered fill material which extends to the native granular subsoils. In no case should any foundation system be placed on the existing on-site fill/landfill debris material. Footings bearing Addendum 1 - 8468 CM/GC for Poudre River Whitewater Park Page 21 of 441 Earth Engineering Consultants, LLC EEC Project No. 1132044 December 8, 2016 Page 13 on approved native granular subsoils or on engineered fill material extended to the granular strata could be designed for a maximum net allowable bearing pressure of 2,500 psf. The coefficient of base friction, assuming a factor of safety of 2, for use with the on-site granular subsoils would be 0.30. If fill material is required to achieve foundation bearing elevations, the engineered fill material should consist of approved imported structural fill placed in uniform lifts; properly moisture conditioned, and mechanically compacted to at least 97% of standard Proctor density (ASTM D698). The net bearing pressure refers to the pressure at foundation bearing level in excess of the minimum surrounding overburden pressure. Overexcavation for placement of the structural fill should extend to the native granular subsoils, and should extend at least eight (8) inches beyond the edges of the foundations for each 12 inches of structural fill placed beneath the footing. We estimate the long-term settlement of footing foundations supported on suitable strength native granular subsoils or engineered fill material, and designed and constructed as outlined above would be about 1-inch or less. Care should be taken during construction to see that the footing foundations are supported on suitable strength native subsoils or approved fill material. If unacceptable materials are encountered at the time of construction, it may be necessary to extend the footing foundations to bear below the unacceptable materials or removal and replacement of the unacceptable materials may be required. Those conditions can best be evaluated in open excavations at the time of construction. No unusual problems, other than any potential environmentally related concerns of the landfill debris, are anticipated in completing the excavations required for construction of the anticipated foundations. Due to the presence of groundwater at varying depths, and depending upon final excavation grades, temporary dewatering may be necessary. Care should be taken during construction to avoid disturbing the foundation bearing materials. Materials which are loosened or disturbed by the construction activities or materials which become dry and desiccated or wet and softened should be removed and replaced prior to placement of foundation concrete. Addendum 1 - 8468 CM/GC for Poudre River Whitewater Park Page 22 of 441 Earth Engineering Consultants, LLC EEC Project No. 1132044 December 8, 2016 Page 14 Wing Wall and Abutment Backfill Backfill soils should consist of approved, low-volume change materials which are free from organic matter and debris. It is our opinion the overburden silty/clayey gravely sand or an essentially granular material such as a CDOT Class 5, 6 or 7 aggregate base course (ABC) could be considered. Backfill soils should be placed in loose lifts with a maximum thickness of 9 inches, adjusted in moisture content and compacted to at least 95% of the material’s standard Proctor maximum dry density. The moisture content of the backfill soils should be adjusted to a workable moisture content. Care should be taken to avoid placing excessive lateral forces immediately behind retaining walls during the compaction process. Lateral Earth Pressures Portions of the pedestrian bridge and retaining structures, including the abutments and wing walls, are anticipated to resist lateral earth pressures. In those areas, active lateral earth pressures would be developed where the foundation element is not restrained from lateral movement. Passive earth pressures are developed in areas where earth pressures are in compression and resisting lateral pressures. Soil parameters are provided below in Table IV for the retained soils consisting of the site silty/clayey gravelly sand. The soil parameters for the backfill material are based specifically for the materials outlined, placed and compacted as recommended in the section titled Wing Wall and Abutment Backfill. The soil parameters outlined below were obtained from general observation of the site soils and are based on the results of both field and laboratory testing completed. The outlined values do not include factors of safety nor allowances for hydrostatic loads and are based on assumed friction angles which should be verified during construction. The outlined soil parameters do not account for surcharges such as adjacent foundations or pavement loads. Care should be taken to develop appropriate drainage systems behind below grade walls to reduce the potential for hydrostatic loads developing behind the walls. Table IV also includes coefficient values for retained soils for calculation of active, at-rest and passive earth pressures. Active lateral earth pressures could be used for design where some movement of the retaining wall is anticipated. The total deflection of retaining wall for design with active earth pressure is estimated to be on the order of one half of one percent of the height Addendum 1 - 8468 CM/GC for Poudre River Whitewater Park Page 23 of 441 Earth Engineering Consultants, LLC EEC Project No. 1132044 December 8, 2016 Page 15 of the down slope side of the structure. We recommend at-rest pressures be used for design of structures where rotation of the walls is restrained from lateral movement. Passive pressures and friction between the footing and bearing soils could be used for design of resistance to movement of retaining walls. The coefficient values are based on horizontal backfill with backfill soils consisting of low volume change soils. Slopes down and away from the structure would result in reduced driving forces with slopes up and away from the structures resulting in greater forces on the walls. The passive resistance would be reduced with slopes away from the wall. Frictional resistance is equal to the tangent of the friction angle (or appropriate friction factor) times the normal force. Surcharge loads or point loads placed in the backfill or behind the retaining walls can also create additional loads on below grade walls. Those situations should be designed on an individual basis.

For those site conditions, the 2015 International Building Code indicates a Seismic Site Classification of D. Addendum 1 - 8468 CM/GC for Poudre River Whitewater Park Page 24 of 441 Earth Engineering Consultants, LLC EEC Project No. 1132044 December 8, 2016 Page 16 Pavement Subgrades Pavement subgrades should be prepared as outlined in the section titled Site Preparation. However, if construction occurs during a wet time of year, it is possible that the site’s silty, clayey sand soils could become wet prior to surfacing. If the silty, clayey sand subsoils become wet, they would be subject to strength loss and instability. To increase the subgrade’s support capacity and stability, consideration could be given to stabilizing the silty, clayey sand subgrades with the addition of Class C fly ash. We estimate stabilization could be accomplished by incorporating at least 12% Class C fly ash (by dry unit weight) into the upper 12 inches of the subgrade. Pavement Sections A Hveem Stabilometer / R-value of 30 was determined for a representative sample of the subgrade silty, clayey sand with trace gravel subsoils. For design purposes we are using an R-Value of 25 to determine the on and off-site pavement thicknesses. The Hveem R-value of 25 correlates to a resilient modulus value of 5816 psi based on the Colorado Department of Transportation (CDOT) correlation. For the on-site pavement improvements we expect the site pavements will include areas designated for low volumes of light weight automobiles (light duty) and areas of light volumes of light delivery and/or garbage trucks (heavy duty). For design purposes we are assuming 18 kip equivalent daily load application (EDLA values of 7 and 15 respectively for the light and heavy duty pavement sections. The Larimer County Urban Area Street Standards (LCUASS) default traffic value of 100 EDLA for a 2-lane industrial/commercial collector (Table 10-1) was used for the pavement design for Vine Drive. A 20-year equivalent single axle load (ESAL) value of 730,000 correlates to an EDLA of 100. Based on the outlined subgrade and traffic inputs, a design weighted structural number (DWSN) of 2.08 and 2.35 were calculated for the pavement design sections for the on-site pavement improvements and a DWSN of 3.32 was calculated for the Vine Drive widening/roadway improvement sections. Alternative pavement designs are indicated below in Tables V and VI.

The HMA should be compacted to be within the range of 92% to 96% of maximum theoretical specific gravity (Rice value) at the time of placement. Aggregate base course should be either Class 5 or Class 6 aggregate base and should be compacted to at least 95% of the materials standard Proctor maximum dry density at the time of placement. Pavement design methods are intended to provide structural sections with adequate thickness over a particular subgrade such that wheel loads are reduced to a level the subgrade can support. The support characteristics of the subgrade for pavement design do not account for shrink/swell movements of either expansive or compressible subgrades. The pavement may be adequate from a structural standpoint, yet still experience cracking and deformation due to shrink/swell related movement of the subgrade. It is, therefore, important to minimize moisture changes in the subgrade to reduce shrink/swell movements. Water Soluble Sulfates – (SO4) The water soluble sulfate (SO4) testing of the on-site overburden subsoils and underlying bedrock revealed approximately 0.02 to 0.08%. Based on the result as presented above, ACI 318, Section 4.2 indicates the site overburden subsoils materials have a low risk of sulfate attack on Portland cement concrete. Based on a low risk criteria, ACI 318 suggests site concrete be developed using a Type I Portland cement. However, if there is no or minimal cost differential, use of ASTM Type II or I/II Portland cement is recommended for additional sulfate resistance of construction concrete. Foundation concrete should be designed in accordance with the provisions of the ACI Design Manual, Section 318, Chapter 4. Other Considerations Positive drainage should be developed across and away from pavement edges to avoid wetting of the pavement subgrades. Subgrade soils allowed to become wetted subsequent to construction can result in poor pavement performance. Addendum 1 - 8468 CM/GC for Poudre River Whitewater Park Page 27 of 441 Earth Engineering Consultants, LLC EEC Project No. 1132044 December 8, 2016 Page 19 High silt content soils can be problematic and certain precautions will be necessary during the design and construction phases of the site to minimize or reduce the potential impact/movement these soils may have. The silt soils and the cohesive materials with elevated silt content are generally unstable at elevated moisture contents, susceptible to frost heave, (especially in areas where shallow groundwater is present) and silts are easily erode able. Frost heave can be completed by using non-frost susceptible soils, removing the water source or reducing the exposure to freezing temperatures. Ground modification procedures as previously discussed herein will be required to enhance the stability and structural integrity of these soils.

DESCRIPTIVE SOIL CLASSIFICATION Soil Classification is based on the Unified Soil Classification system and the ASTM Designations D‐2488. Coarse Grained Soils have move than 50% of their dry weight retained on a #200 sieve; they are described as: boulders, cobbles, gravel or sand. Fine Grained Soils have less than 50% of their dry weight retained on a #200 sieve; they are described as : clays, if they are plastic, and silts if they are slightly plastic or non‐plastic. Major constituents may be added as modifiers and minor constituents may be added according to the relative proportions based on grain size. In addition to gradation, coarse grained soils are defined on the basis of their relative in‐ place density and fine grained soils on the basis of their consistency. Example: Lean clay with sand, trace gravel, stiff (CL); silty sand, trace gravel, medium dense (SM).

These activities were conducted on the north and south banks of the Cache la Poudre River (Poudre River) near North College Avenue and the BNSF Railway trestle bridge in Fort Collins, Colorado. Select site assessment activities were conducted on the Colorado State University Powerhouse Energy Campus located at 430 North College Avenue. This project was conducted for the City of Fort Collins under the General Environmental Services Contract Number 7436 and an executed City of Fort Collins Work Order Form dated April 3, 2014. The Site and properties located adjacent to or near the Site have historically been used for a variety of industrial operations including power generation, research and development, manufactured gas generation, petroleum storage and distribution, landfill, vehicle maintenance, as well as other commercial activities. Previous investigations by various researchers have documented the presence of soil, groundwater, and soil vapor contamination in the vicinity of the Site. 2 PURPOSE AND SCOPE OF THE SITE INVESTIGATION The proposed activities are based on conceptual plans for the Poudre River Downtown Project provided by Anderson Consulting Engineers, Inc., a review of available historic and recent environmental information related to the Site and nearby properties, and information conveyed in meetings/interviews/telephone conversations/email correspondence with City of Fort Collins, Colorado State University, and Anderson Consulting Engineers, Inc. representatives and their subcontractors/subconsultants. Walsh understands that principal proposed construction activities in the immediate vicinity of the Site will include removal or reconfiguring of the Coy Diversion and Boat Chute structures, re- grading (lowering) the channel bed, installation of fish passage structures, and in-stream habitat improvements. To complete these activities, conceptual design plans anticipate the removal of existing in-stream unconsolidated alluvium (sediment) and up to approximately two feet of underlying bedrock in select portions of the Poudre River. Re-configuring the banks adjacent to the Poudre River is also planned. The principal objective of this project was to determine if non-aqueous phase liquid (NAPL) contamination from the nearby Poudre River/Aztlan Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) Removal Action Site is present and could be Addendum 1 - 8468 CM/GC for Poudre River Whitewater Park Page 63 of 441 Environmental Scientists and Engineers, LLC WA-002011-0024-10TTO Poudre River Downtown Project Phase II ESA Report.docx 2 encountered in the vicinity of the proposed construction area near the Poudre River. In addition, the project also assessed the presence and potential to encounter contaminants from other sources in the vicinity of the Site which may affect proposed construction activities. The chemicals of concern identified for this project included volatile organic compounds, polycyclic aromatic hydrocarbons, eight Resource Conservation and Recovery Act metals, total recoverable petroleum hydrocarbons (as oil and grease), and asbestos. Investigation derived waste required classification for ignitability, corrosivity, and reactivity (cyanide and sulfide). This was a targeted assessment so only select samples were analyzed for these analytical parameters. To achieve the stated objectives as part of the project scope, the following activities were performed:  Advanced three (3) soil borings and installed three (3) temporary monitoring wells to determine presence of potential soil and shallow alluvial groundwater contamination. Collected representative subsurface soil and groundwater samples from each boring/well.  Advanced six (6) soil borings and installed six (6) permanent monitoring wells to determine presence of potential soil and bedrock aquifer groundwater contamination. Collected representative subsurface soil and groundwater samples from each boring/well.  Collected representative groundwater samples from three (3) existing wells to determine presence of potential bedrock aquifer groundwater contamination.  Collected ten (10) area equivalent air monitoring samples for asbestos/fibers.  Collected representative samples of investigation derived waste (soil and water) for waste determination and disposal purposes.  Submitted representative samples collected at the Site for laboratory analyses.  Reviewed and assessed field and analytical data generated during the assessment, compared analytical results to current Federal and State environmental regulations/guidelines, and compiled information into comprehensive report. All figures referenced in the text of this report are included in Appendix A. Tables are included in Appendix B, soil boring logs/monitoring well construction details are included in Appendix C, and groundwater sampling field data sheets are included in Appendix D. Laboratory data and associated chain-of-custody forms are included in Appendix E. Asbestos air monitoring field data sheets are included in Appendix F of this report. 3 SITE INVESTIGATION ACTIVITIES 3.1 Investigation of Utilities Walsh performed an underground utilities investigation in the vicinity of the proposed soil boring/monitoring well locations at the Site on April 10, 2014. This investigation included field reconnaissance in the vicinity of the Site and location of utilities by various utility company representatives. The locations of the utilities were marked with spray paint and flagging by utility company representatives. The final locations of select borings were modified based on the presence of buried utilities, other restrictive site conditions, and private landowners not granting access to their property. Addendum 1 - 8468 CM/GC for Poudre River Whitewater Park Page 64 of 441 Environmental Scientists and Engineers, LLC WA-002011-0024-10TTO Poudre River Downtown Project Phase II ESA Report.docx 3 3.2 Soil Boring and Subsurface Soil Sampling The proposed soil boring locations were selected based on a review of historic documentation related to the Site and on observations made during preliminary site visits. The proposed soil boring locations were also selected based on the understanding of the regional and local groundwater gradient. A total of nine soil borings were advanced at the Site (FC-MW-15 to FC-MW-23). Figure 1 in Appendix A depicts the locations of the soil boring locations. Boring depths ranged from 12.0 to approximately 40.0 feet below ground surface. The borings were used to investigate potential soil and/or groundwater contamination, as well as for temporary and permanent monitoring well installation purposes. All soil borings were advanced using a Central Mine Equipment-75 drill rig equipped with 4.25-inch inside diameter and 8.25-inch outside diameter hollow stem augers. A 5-foot long continuous core barrel sampler was used on the majority of borings, when feasible. Difficult drilling conditions encountered during the advancement of soil borings FC-MW-17, and FC-MW-21 to FC-MW-23 required the use of a center plug instead of the continuous samples for select subsurface intervals. All soil borings were advanced from the existing ground surface to desired drilling depth (or until equipment refusal). Continuous soil cores obtained from borings were visually inspected for unusual staining and each interval was screened for the presence of volatile organic compounds (VOCs) using a hand- held Rae Systems® photoionization detector (PID). Soil cores displaying strong, pungent or noticeable odors were also noted. The lithology of the soil core samples was described by Walsh personnel using the Unified Soil Classification System (USCS). Soils encountered in the borings generally consisted of brown to dark-brown silty clays at the surface. In many of the borings, this material was underlain by tan to dark-brown very fine to fine grained silty sands. This material was typically underlain by brown clayey gravels and/or tan, gray, and dark-brown gravelly sands. In the deeper (bedrock) borings, an olive-tan colored weathered fine grained sandstone was encountered. The weathered sandstone interval was underlain by a light-gray to light-blue fine grained sandstone. In select borings, the sandstone contained thin light-green to green, dark-gray, and brownish-black intervals. Soil lithology details and PID readings recorded for the soil core samples are included in Appendix C. Landfill debris consisting of brick, ceramics, cinders, coal, glass, metal, wire, and/or wood were present in borings FC-MW-15 to FC-MW-20. No suspect asbestos-containing building debris was observed in any of the soil borings. Soil intervals from borings FC-MW-17 to FC-MW-20 displayed visible dark-gray to black staining at depths between approximately 8 and 11 feet below ground surface. A moderate petroleum odor was observed from the stained interval in boring FC-MW-18. In the majority of the borings where staining was present, elevated PID readings were not observed. The PID reading from boring FC-MW-18 where the staining was present was recorded at a relatively low concentration of 1.9 parts per million (ppm). It is likely that these stained intervals are related to historic petroleum contaminant migration from either the Site or off-Site source(s). A soil interval from boring FC-MW-23 displayed visible brownish-black staining at a depth of approximately 17.5 to 18 feet below ground surface. No odor was noted and a relatively low PID reading of 3.7 ppm was recorded from this stained Addendum 1 - 8468 CM/GC for Poudre River Whitewater Park Page 65 of 441 Environmental Scientists and Engineers, LLC WA-002011-0024-10TTO Poudre River Downtown Project Phase II ESA Report.docx 4 interval. Due to the proximity to the NAPL contamination from the nearby Poudre River/Aztlan CERCLA Removal Action Site an opportunity sample (FC-MW-23A) was collected from this stained interval. Recorded PID readings collected from soil samples during the investigation ranged from 0.2 to 8.1 ppm. In general, subsurface soil samples were collected from visibly stained intervals and/or the interval which displayed the highest elevated reading on the PID instrument. If staining or detectable volatile organic concentrations were not present in a particular boring, the soil sample was collected from the interval located directly above the presumed water table interface. For select deep bedrock wells, representative subsurface soil/bedrock samples were collected at depths below the shallow alluvial aquifer. Subsurface soil samples were immediately placed in laboratory supplied pre-labeled sample jars, stored within an ice-filled cooler and chilled to approximately four degrees Celsius, and subsequently hand delivered to the laboratory under appropriate chain-of-custody protocols. Figure 1 in Appendix A depicts the subsurface soil sample locations. Select subsurface soil samples were submitted to the laboratory for volatile organic compounds (VOCs), polycyclic aromatic hydrocarbons (PAHs), total recoverable petroleum hydrocarbons [as oil and grease (O&G)], and eight Resource Conservation and Recovery Act (RCRA) total metals analyses. Detected subsurface soil sample results are summarized in Table 1 in Appendix B, and the complete laboratory analytical reports indicating all analytical parameters are included in Appendix E. 3.3 Groundwater Monitoring Well Installation and Sampling 3.3.1 Temporary Monitoring Wells Three temporary monitoring wells (FC-MW-18 to FC-MW-20) were installed for shallow alluvial aquifer monitoring purposes. These wells were constructed in the borings as “open hole” completions to total depths ranging from approximately 10.5 to 13.5 feet below ground surface. The temporary monitoring wells were constructed of 2-inch outside diameter threaded Schedule 40 polyvinyl chloride (PVC) pipe. A threaded PVC end (bottom) cap was installed to the base of each well. Screened PVC sections (10-foot lengths, 0.010-inch slots) were installed to the base of each borehole. Solid PVC riser sections were used to extend the well casing to a level above grade. Locking caps were installed at the top of each well. When the augers were removed from the borings, native silty sands and gravelly sands collapsed around the well screen and provided a natural gravel pack. Monitoring wells were constructed to total depths of approximately 10.5 to 12 feet below ground surface. Groundwater was then allowed to infiltrate the temporary wells. Temporary monitoring well construction details are included in Appendix C. Figure 1 in Appendix A depicts the locations of the temporary monitoring wells. Walsh collected grab groundwater samples from the temporary monitoring wells on April 18, 2014. All temporary monitoring wells were sampled using dedicated polyethylene bailers. Temperature, specific conductivity, and pH were measured and recorded on groundwater field forms for each temporary monitoring well sample. Samples collected for dissolved metals Addendum 1 - 8468 CM/GC for Poudre River Whitewater Park Page 66 of 441 Environmental Scientists and Engineers, LLC WA-002011-0024-10TTO Poudre River Downtown Project Phase II ESA Report.docx 5 analyses were filtered in the field using a peristaltic pump, dedicated polyethylene tubing, and disposable 0.45 micron filters. Copies of groundwater sampling field forms are included in Appendix D. All groundwater samples were immediately placed in laboratory supplied pre-labeled sample bottles, stored within an ice-filled cooler and chilled to approximately four degrees Celsius, and subsequently hand delivered to the laboratory under appropriate chain-of-custody protocols. Groundwater samples from the temporary wells were submitted to the laboratory for VOCs and eight RCRA dissolved metal analyses. Detected groundwater sample results are summarized in Table 2 in Appendix B, and laboratory analytical reports are included in Appendix E. The temporary monitoring wells were abandoned on April 18, 2014 in accordance with Colorado Water Well Construction Rules (CDWR, 2005). 3.3.2 Permanent Monitoring Wells Six permanent monitoring wells (FC-MW-13 to FC-MW-15 and FC-MW-21 to FC-MW-23) were installed for bedrock aquifer monitoring purposes and were constructed according to Colorado Division of Water Resources (CDWR) Colorado Water Well Construction Rules (CDWR, 2005). These wells were constructed within the borings to total depths ranging from approximately 30 to 39.5 feet below ground surface. The permanent monitoring wells were constructed of 2-inch outside diameter, Schedule 40 threaded PVC pipe equipped with threaded bottom caps. Screened PVC sections (10-foot lengths, 0.010-inch slots) were installed from total boring depth to a depth below the top of bedrock. Solid 2-inch PVC riser sections were used to extend the well casing to approximately 0.3- to 0.5 feet below ground surface. Silica sand (10 x 20 mesh) was poured into the annulus surrounding the PVC to approximately 2 feet above the screened interval, slow release bentonite pellets (two foot thickness) were added onto the top of the sand, and granular bentonite chips were added from the top of the bentonite pellets to approximately 0.75 feet below the surface to seal the annular space. The bentonite was hydrated with a limited quantity (1 to 1.5 gallons) of distilled water. The wells were sealed with locking caps and covered with flush-mounted 9.25-inch diameter well protectors equipped with 12-inch skirts that were set into concrete pads measuring 2-feet by 2-feet. Permanent monitoring well construction details are included in Appendix C. Figure 1 in Appendix A depicts the locations of the permanent monitoring wells. Permanent monitoring wells were developed on April 21 and 22, 2014. Development activities included purging/removing approximately ten gallons of groundwater with disposable polyethylene bailers. The objective of well development activities was to decrease turbidity and the amount of fine sediments present and to remove disturbed and stagnant water from drilling operations to ensure that groundwater was representative of the formation when sampled. Walsh collected groundwater samples from the six permanent monitoring wells (FC-MW-15 to FC-MW-17 and FC-MW-21 to FC-MW-23) on April 22, 2014. All wells were purged prior to sample collection. During well purging and prior to sample collection, the water was field tested Addendum 1 - 8468 CM/GC for Poudre River Whitewater Park Page 67 of 441 Environmental Scientists and Engineers, LLC WA-002011-0024-10TTO Poudre River Downtown Project Phase II ESA Report.docx 6 for temperature, specific conductivity, and pH. The stabilization of these field measurements and the total volume of water purged assured that the groundwater sample was representative of the formation. Samples collected for dissolved metals analyses were filtered in the field using a peristaltic pump, dedicated polyethylene tubing, and disposable 0.45 micron filters. Completed field groundwater sampling forms are included in Appendix D. All groundwater samples were immediately placed in laboratory supplied pre-labeled sample bottles, stored within an ice-filled cooler and chilled to approximately four degrees Celsius, and subsequently hand delivered to the laboratory under appropriate chain-of-custody protocols. Groundwater samples were submitted to the laboratory for VOCs, PAHs, and eight RCRA dissolved metal analyses. Detected groundwater sample results are summarized in Table 2 in Appendix B, and laboratory analytical reports are included in Appendix E. 3.3.3 Existing Monitoring Well Sampling Walsh collected representative groundwater samples from three existing monitoring wells (FC- MW-13, FC-MW-14, and PRBB-22) at the Site for bedrock aquifer monitoring purposes on April 21, 2014. Figure 1 in Appendix A depicts the locations of the existing monitoring wells. All wells were purged prior to sample collection. Prior to sample collection, the purge water was field tested for temperature, specific conductivity, and pH. The stabilization of these field measurements and the total volume of water purged assured that the groundwater sample was representative of the formation. Completed field groundwater sampling forms are included in Appendix D. The groundwater samples were immediately placed in laboratory supplied pre-labeled sample bottles, stored within an ice-filled cooler and chilled to approximately four degrees Celsius, and subsequently hand delivered to the laboratory under appropriate chain-of-custody protocols. The groundwater samples were submitted to the laboratory for PAHs analyses. Detected groundwater sample results are summarized in Table 2 in Appendix B, and laboratory analytical reports are included in Appendix E. 3.4 Asbestos Sampling 3.4.1 Asbestos/Fibers Air Samples Portions of the Site are located within the boundaries of the Poudre River/Aztlan Site Soil Characterization and Management Plan (SCMP) which addresses characterization and management of potential asbestos-contaminated soil and asbestos-containing materials. While performing soil disturbing activities on the 430 North College Avenue portion of the Site, all field activities were performed in compliance with applicable requirements specified in the SCMP dated August 24, 2010 and the SCMP Addendum dated May 5, 2011 (Walsh, 2010 and Walsh, 2011). Area equivalent air monitoring was conducted in accordance with U.S. Environmental Protection Agency (USEPA) and Colorado Department of Public Health and Environment (CDPHE) requirements to determine ambient fiber concentrations. The air samples Addendum 1 - 8468 CM/GC for Poudre River Whitewater Park Page 68 of 441 Environmental Scientists and Engineers, LLC WA-002011-0024-10TTO Poudre River Downtown Project Phase II ESA Report.docx 7 were collected by a CDPHE certified air monitoring specialist (AMS) using 25 millimeter, 0.8 micron mixed cellulose filter cassettes using low-flow personal sampling pumps. Flow rates were set at approximately 2 liters per minute (LPM). The samples were collected at a breathing zone height (of approximately five feet) and the cassettes were positioned facing downward at a 45-degree angle. A minimum of two area equivalent ambient air samples were collected during all soil disturbing activities. Sample locations were determined by the AMS. One sample was collected on the drilling rig operator and one sample was collected on the drill rig helper. Additionally, with each round of air samples collected, a minimum of two unused samples were analyzed as blank correction factors. Field worksheets were completed for the air samples collected and are included in Attachment F. These sheets are designed to function as the primary working document, containing most information regarding the air sampling. The air samples were subsequently analyzed by phase contrast microscopy (PCM) techniques by Walsh personnel who participate in the National Institute for Occupational Safety and Health (NIOSH) Proficiency Analytical Testing program. Samples analyzed by PCM methods are reported as fibers per cubic centimeter (f/cc) of air sampled. Detected asbestos/fiber ambient air sample results are summarized in Table 3 in Appendix B and laboratory analytical data is included in Appendix E. Asbestos/fiber air monitoring field data sheets are included in Appendix F. 3.5 Groundwater Elevation Data Groundwater elevation data (water depth below ground surface and top of inner monitoring well casing) was obtained using a water level indicator. All permanent monitoring wells were surveyed by means of a Global Positioning System unit. Colorado State Plane coordinate system was used for the standard horizontal datum and North American Datum (NAD) 1983/2000 was used as the standard vertical datum system. The depth to groundwater at the Site ranged from 2.25 to 21.85 feet below ground surface. Based on surveyed monitoring well elevations and the observed groundwater elevations from the permanent monitoring wells, a relative groundwater elevation (potentiometric surface) map was prepared for the bedrock wells at the Site (Appendix A, Figure 2). Relative groundwater elevation contours at the Site indicate that in the areas sampled, the general groundwater flow direction in bedrock aquifer is to the east-southeast. 3.6 Boring Abandonment The temporary monitoring wells were abandoned in accordance with Colorado Water Well Construction Rules following the completion of the groundwater sample collection activities. A description of the well abandonment methods are summarized below:  The depth to groundwater was measured.  The temporary PVC well was pulled from the boring by hand.  The depth was measured again to determine if native materials (sands and gravels) had collapsed above the groundwater level. Addendum 1 - 8468 CM/GC for Poudre River Whitewater Park Page 69 of 441 Environmental Scientists and Engineers, LLC WA-002011-0024-10TTO Poudre River Downtown Project Phase II ESA Report.docx 8  If collapse had not occurred above groundwater level, the boring was filled with 10 x 20 mesh clean silica sand to a level approximately one foot above the groundwater level.  The boring was then filled with granular bentonite chips from the top of sand to approximately six inches below ground surface.  Surrounding surficial soils were used to fill the boring to the ground surface. 3.7 Investigation Derived Wastes Investigation derived waste (i.e., excess soil material from cores and drill cuttings, well development and purge water, and decontamination water) was stored in U.S Department of Transportation approved 55-gallon steel drums which are being temporarily staged at the Site. Representative samples of the investigation derived wastes (soil and water) were collected. Soil samples were analyzed for VOCs, PAHs, O&G, and eight RCRA toxicity characteristic leaching procedure (TCLP) metal analyses. Water samples were analyzed for ignitability, corrosivity (as pH), reactivity (cyanide and sulfide), VOCs, PAHs, and eight RCRA TCLP metal analyses. Laboratory results indicate the investigation derived wastes exhibit non-hazardous characteristics. The investigation derived wastes have been profiled and will subsequently be transported for off-site disposal. 4 LABORATORY ANALYSES Soil, groundwater, and investigation derived waste samples were submitted for laboratory analyses to ALS Environmental located in Fort Collins, Colorado. Detected subsurface soil sample results from the investigation are summarized in Appendix B, Table 1. Detected groundwater sample results are summarized in Appendix B, Table 2. Asbestos/Fibers (area equivalent ambient air) sample results are summarized in Appendix B, Table 3. Laboratory analytical reports and chain-of-custody documentation is included in Appendix E. 4.1 VOCs in Soils Select soil samples were analyzed for VOCs by USEPA Method 8260C. Soil sample results showed low detectable concentrations of VOCs in samples FC-MW-18 to FC-MW-20. VOCs detected include 2-butanone (also known as methyl ethyl ketone), acetone, and carbon disulfide. No VOCs were detected in soil at concentrations greater than USEPA Regional Screening Level (RSL) standards for industrial land use or CDPHE Groundwater Protection Values Soil Cleanup (GPVSC) standards (USEPA, 2013 and CDPHE, 2014). 4.2 PAHs in Soils Select soil samples were analyzed for PAHs by USEPA Method 8270D. Detectable concentrations of PAHs were reported in soil sample FC-MW-17A. Sample FC-MW-17A was collected from a visually stained (dark gray to black) soil interval present at a depth of 9 to 11 feet below ground surface. This sample was collected from a portion of the Site where landfill materials were present. The reported concentrations of benzo (a) anthracene, benzo (a) pyrene, Addendum 1 - 8468 CM/GC for Poudre River Whitewater Park Page 70 of 441 Environmental Scientists and Engineers, LLC WA-002011-0024-10TTO Poudre River Downtown Project Phase II ESA Report.docx 9 benzo (b) fluoranthene, dibenzo (a, h) anthracene, and indeo (1, 2, 3-cd) pyrene exceeded either the USEPA RSL standards for industrial land use, the CDPHE GPVSC standards, and/or the Colorado Department of Labor and Employment - Division of Oil and Public Safety (OPS) Risk Based Screening Level (RBSL) for subsurface soil at FC-MW-17A (OPS, 2005). These PAHs are a common byproduct of burning of fuel oil and coal and are often present in former industrial areas. No PAHs were detected in soil samples collected from deeper bedrock intervals (FC-MW-15B, FC-MW-16B, FC-MW-17B, and FC-MW-21 to FC-MW-23) which indicate that NAPL contamination from the nearby Poudre River/Aztlan CERCLA Removal Action Site was not present at these locations. 4.3 Metals in Soils Select soil samples were analyzed for the RCRA eight metals (arsenic, barium, cadmium, chromium, lead, mercury, selenium, and silver) by USEPA Method 6020 with the exception of mercury, which was analyzed by USEPA Method 7471A. With the exception of arsenic, detected concentrations of all other metals were below the applicable USEPA RSL standards for industrial land use. 4.3.2 Arsenic in Soils Detectable concentrations of arsenic were reported in soil samples FC-MW-15A, FC-MW-16A, FC-MW-17A, and FC-MW-18 to FC-MW-20. The arsenic concentrations at these locations exceeded the USEPA RSL of 2.4 milligrams per kilogram (mg/kg) for industrial land use. Arsenic concentrations ranged from 2.8 mg/kg to 6.7 mg/kg in soil samples collected at the Site. Arsenic occurs naturally at levels above USEPA RSL standard in soils and weathered bedrock in Colorado but also occurs as the result of anthropogenic activities. Therefore, arsenic concentrations were compared to the USEPA Region 8, 95% upper confidence limit of the mean background soil arsenic concentrations in Colorado (CDPHE, 2011). An average background soil arsenic concentration of 11 mg/kg has been established for all land use areas (including agricultural, mining, native grassland, rangeland, and urban mixed use) areas. A background soil arsenic concentration of 19 mg/kg has been established for urban mixed land use areas. Arsenic concentrations detected at the Site are below the established CDPHE average background soil concentration for all land use areas, as well as the background soil concentration established for urban mixed land use areas. 4.4 Total Recoverable Petroleum Hydrocarbons (O&G) in Soils Select soil samples were analyzed for total recoverable petroleum hydrocarbons (O&G) by USEPA Method 9071B. Detectable concentrations of O&G were reported in soil samples FC- MW-17A, and FC-MW-18 to FC-MW-20. Concentrations of O&G in soil samples FC-MW- 17A (2,500 mg/kg) and FC-MW-19 (530 mg/kg) exceeded the OPS threshold value of 500 mg/kg. Addendum 1 - 8468 CM/GC for Poudre River Whitewater Park Page 71 of 441 Environmental Scientists and Engineers, LLC WA-002011-0024-10TTO Poudre River Downtown Project Phase II ESA Report.docx 10 4.5 VOCs in Groundwater Select groundwater samples were analyzed for VOCs by USEPA Method 8260C. Groundwater sample results showed low detectable concentrations of VOCs in samples FC-MW-15, FC-MW- 17, FC-MW-19, and FC-MW-20. VOCs detected include 2-butanone (also known as methyl ethyl ketone), acetone, benzene, carbon disulfide, and toluene. Most of the VOCs were detected by the laboratory at estimated (J-flagged) concentrations. Detected concentrations of VOCs did not exceed the CDPHE Water Quality Control Commission water quality standards and/or maximum contaminant levels (MCLs), or the OPS RBSLs for groundwater ingestion (CDPHE, 2013 and OPS, 2005). 4.6 PAHs in Groundwater Select groundwater samples were analyzed for PAHs by USEPA Method 8270D. No PAHs were detected in the groundwater samples above the method detection limits. All groundwater PAH samples were collected from existing and new bedrock monitoring wells. The absence of detectable concentrations of PAH compounds in these wells indicates that NAPL contamination from the nearby Poudre River/Aztlan CERCLA Removal Action Site was not present at these locations. 4.7 Metals in Groundwater Select groundwater samples were analyzed for the RCRA eight metals by USEPA Method 6020 and USEPA Method 7471A. The detected concentration of arsenic in sample FC-MW-20 [18 micrograms per liter (µg/L)] exceeded the CDPHE water quality standard/MCL of 10 µg/L. Trace concentrations of other metals were detected in samples FC-MW-15 to FC-MW-20. Detected concentrations of all other metals were below the applicable CDPHE water quality standards. 4.8 Asbestos Sample Results 4.8.1 Asbestos/Fibers in Ambient Air The air samples were analyzed by PCM NIOSH Method 7400A, which is not asbestos specific. The PCM sample results are reported as fibers per cubic centimeter (f/cc) of air sampled. The SCMP for the Site establishes a limit of 0.010 f/cc when using PCM methods. Three of the air samples could not be analyzed due to excessive loading of the sampling media and were reported as “cannot be read” (CBR). Since these samples could not be analyzed they cannot be compared to the established limit. None of the air samples collected and analyzed exceeded the established limit. Addendum 1 - 8468 CM/GC for Poudre River Whitewater Park Page 72 of 441 Environmental Scientists and Engineers, LLC WA-002011-0024-10TTO Poudre River Downtown Project Phase II ESA Report.docx 11 5 CONCLUSIONS Contaminants of concern were found to be present in select subsurface soil and groundwater samples at concentrations exceeding USEPA RSL standards for industrial land use, CDPHE GPVSC standards, OPS RBSL standards/threshold values, and/or CDPHE water quality standards/MCLs. Results from this investigation are similar to findings obtained during a previous assessment performed on the Site and adjoining properties (WALSH, 2011a). In 2012, a No Action Determination was issued for the 430 North College Avenue portion of the Site by the CDPHE Voluntary Cleanup Program. This No Action Determination included findings that based on a review of environmental assessment data, no evidence of contamination was identified which exceeded applicable promulgated standards or posed an unacceptable risk to human health or the environment (CDPHE, 2012). Soils PAH compounds were detected at concentrations exceeding USEPA RSL standards for industrial land use, CDPHE GPVSC standards, and/or the OPS RBSL for subsurface soil at FC-MW-17A. These PAHs were present at a depth of 9 to 11 feet below ground surface from a portion of the Site where landfill materials were present. No PAHs were detected in soil samples collected from deep bedrock intervals which indicate that NAPL contamination from the nearby Poudre River/Aztlan CERCLA Removal Action Site was not present at these locations. Detectable concentrations of arsenic were reported in soil samples FC-MW-15A, FC-MW-16A, FC-MW-17A, and FC-MW-18 to FC-MW-20. The arsenic concentrations at these locations exceeded the USEPA RSL but are below the established CDPHE average background soil concentration for all land use areas, as well as the background soil concentration established for urban mixed land use areas. Detectable concentrations of O&G were reported in soil samples FC-MW-17A, and FC-MW-18 to FC-MW-20. The O&G concentrations at FC-MW-17A and FC-MW-19 exceeded the OPS threshold value. Visible staining was observed at these locations at depths between approximately 8 to 11 feet below ground surface and is likely a result of a historic petroleum release(s) from Site and/or off-Site source(s). Materials or debris suspected to contain asbestos were not identified while performing soil disturbing activities during this investigation. Due to presence and relatively heterogeneous nature of the landfill materials located at the 430 North College Avenue portion of the Site, there is a high potential of encountering asbestos-containing debris and/or asbestos-contaminated soil during future soil disturbing activities on this portion of the Site. Groundwater The detected concentration of arsenic at FC-MW-20 exceeded the CDPHE water quality standard/MCL. The shallow alluvial aquifer underlying the Site is not being used as a drinking water source.

Potentially contaminated soils at the Site should be characterized and managed in accordance with a Materials Management Plan which will limit exposures and ensure the proper disposal of all impacted materials in accordance with local, state, and federal environmental regulations. Due to the high potential to encounter asbestos-containing debris and/or asbestos-contaminated soil, all future soil disturbing activities on the 430 North College Avenue portion of the Site should be performed in accordance with the CDPHE approved Soil Characterization and Management Plan (SCMP) for the Site. 7 REFERENCES CDPHE. 2011.

This report consists of four water samples and seven soil samples. The samples were received intact at 8.2°C by ALS on 04/18/14. The water samples were free of headspace prior to analysis. Sample 1404340-15, provided for volatiles, had a pH > 2 at the time of analysis. All other water samples and had a pH < 2 at the time of analysis. 2. The sample was prepared according to SW-846, 3rd Edition procedures. Specifically: The water samples were prepared using purge and trap procedures based on Method 5030C. The soil samples were prepared using a heated purge based on Method 5035A. 3. The samples were analyzed using GC/MS with an RTX-624, RTX-VMS, or equivalent capillary column according to the current revision of SOP 525 based on SW-846 Method 8260. All positive results were quantitated against the initial calibration standards using the internal standard technique. The identification of positive results was achieved by a comparison of the retention time and mass spectrum of the sample versus the daily calibration standard. 4. All criteria for the initial calibration were met. 5. All initial calibrations are verified by comparing a second source standard calibration verification (ICV) against the calibration curve. All criteria for initial calibration verification were met. 6. All compounds in the continuing calibration verification had a %D of less than 20% with the following exceptions: Acetone was high on 04/22/14 HPV2. This compound was detected in the associated samples so the data were flagged. Acetone was high on 04/23/14 HPV2. This compound was not detected in the associated sample. Addendum 1 - 8468 CM/GC for Poudre River Whitewater Park Page 109 of 441 Addendum 1 - 8468 CM/GC for Poudre River Whitewater Park Page 110 of 441 ALS Data Qualifier Flags Chromatography and Mass Spectrometry U or ND: This flag indicates that the compound was analyzed for but not detected. J: This flag indicates an estimated value. This flag is used as follows : (1) when estimating a concentration for tentatively identified compounds (TICs) where a 1:1 response is assumed; (2) when the mass spectral and retention time data indicate the presence of a compound that meets the volatile and semivolatile GC/MS identification criteria, and the result is less than the reporting limit (RL) but greater than the method detection limit (MDL); (3) when the retention time data indicate the presence of a compound that meets the GC identification criteria, and the result is less than the RL but greater than the MDL; and (4) the reported value is estimated. B: This flag is used when the analyte is detected in the associated method blank as well as in the sample. It indicates probable blank contamination and warns the data user. This flag shall be used for a tentatively identified compound (TIC) as well as for a positively identified target compound. E: This flag identifies compounds whose concentration exceeds the upper level of the calibration range. A: This flag indicates that a tentatively identified compound is a suspected aldol- condensation product. X: This flag indicates that the analyte was diluted below an accurate quantitation level. *: This flag indicates that a spike recovery is equal to or outside the control criteria used. +: This flag indicates that the relative percent difference (RPD) equals or exceeds the control criteria. G: This flag indicates that a pattern resembling gasoline was detected in this sample. H: This flag indicates that the fuel pattern was in the heavier end of the retention time window for the analyte of interest. L: This flag indicates that the fuel pattern was in the lighter end of the retention time window for the analyte of interest. Z: This flag indicates that a significant fraction of the reported result did not resemble the patterns of any of the following petroleum hydrocarbon products: gasoline JP-8 diesel mineral spirits motor oil Stoddard solvent bunker C Addendum 1 -

This report consists of 11 soil samples. The samples were received intact at 8.2°C by ALS on 04/18/14. 2. These samples were prepared and analyzed according to SW-846, 3rd Edition procedures. Specifically, the soil samples were extracted using soxhlet procedures according to SW-846 Method 3540C, utilizing the current revision of SOP 625. These extracts were then processed using GPC cleanup according to the current revision of SOP 641 based on Method 3640A in an attempt to remove potential interferences. 3. The extracts were analyzed using GC/MS with a DB-5MS capillary column according to the current revision of SOP 506 based on SW-846 Method 8270D. All positive results were quantitated against the initial calibration standards using the internal standard technique. The identification of positive results was achieved by a comparison of the retention time and mass spectrum of the sample versus the daily calibration standard. 4. All initial calibration criteria were met. If average response factors were used in the initial calibration, %RSD was ≤20%. If linear or higher order regression calibrations were used in the initial calibration, the coefficient of determination (r2) ≥0.99. 5. All initial calibration standards are verified by comparing a second source standard initial calibration verification (ICV) against the calibration curve. All target compounds in the second source verification had a %D ≤30%. 6. All compounds in each of the daily (continuing) calibration verifications were within 20%D with the exception of dibenzo(a,h)anthracene which was high. This compound was not detected in the associated samples. 7. All method blank criteria were met. 8. All laboratory control sample recoveries were within the acceptance criteria. Addendum 1 - 8468 CM/GC for Poudre River Whitewater Park Page 166 of 441 9. Sample 1404340-18 was designated as the quality control sample for this analysis. Similarity of matrix and therefore relevance of the QC results should not be automatically inferred for any sample other than the native sample selected for QC. All matrix spike and matrix spike duplicate recoveries and RPDs were within acceptance criteria with the following exceptions: Spiked Compound QC Sample Direction Anthracene MS Low Indeno(1,2,3-cd)pyrene MS & MSD Low Dibenzo(a,h)anthracene MS & MSD Low Benzo(g,h,i)perylene MS & MSD Low The recoveries of these compounds in the laboratory control sample were within control limits, which suggest the outliers in the matrix spikes may have been due to matrix effects, so no further action was taken. 10. The samples were extracted and analyzed within the established holding times. 11. All surrogate recoveries were within acceptance criteria. Sample 1404340-2MS was mistakenly spiked with twice the amount of surrogate required. See NCR #14064 at the end of this report for further documentation. 12. All internal standard recoveries were within acceptance criteria with the following exception: Internal Standard Sample Direction Perylene-D12 1404340-5 Low Analysis of the sample at a dilution showed all internal standard recoveries passing. This suggests that the outliers were due to matrix effects. No further action was taken. 13. Due to the matrix, sample 1404340-5 had an elevated final volume. The reporting limits have been adjusted accordingly. 14. Manual integrations are performed when needed to provide consistent and defensible data following the guidelines in the current revision of SOP 939. Addendum 1 - 8468 CM/GC for Poudre River Whitewater Park Page 167 of 441 Addendum 1 - 8468 CM/GC for Poudre River Whitewater Park Page 168 of 441 ALS Data Qualifier Flags Chromatography and Mass Spectrometry U or ND: This flag indicates that the compound was analyzed for but not detected. J: This flag indicates an estimated value. This flag is used as follows: (1) when estimating a concentration for tentatively identified compounds (TICs) where a 1:1 response is assumed; (2) when the mass spectral and retention time data indicate the presence of a compound that meets the volatile and semivolatile GC/MS identification criteria, and the result is less than the reporting limit (RL) but greater than the method detection limit (MDL); (3) when the retention time data indicate the presence of a compound that meets the GC identification criteria, and the result is less than the RL but greater than the MDL; and (4) the reported value is estimated. B: This flag is used when the analyte is detected in the associated method blank as well as in the sample. It indicates probable blank contamination and warns the data user. This flag shall be used for a tentatively identified compound (TIC) as well as for a positively identified target compound. E: This flag identifies compounds whose concentration exceeds the upper level of the calibration range. A: This flag indicates that a tentatively identified compound is a suspected aldol-condensation product. X: This flag indicates that the analyte was diluted below an accurate quantitation level. *: This flag indicates that a spike recovery is equal to or outside the control criteria used. +: This flag indicates that the relative percent difference (RPD) equals or exceeds the control criteria.

This report consists of 1 TCLP sample, 6 soil samples, and 3 water samples. 2. The samples that were received by ALS on 04/18/14 were intact at 8.2°Celcius. The samples that were received by ALS on 04/21/14 were intact at 15.4°Celcius. 3. The water samples were to be analyzed for dissolved metals. The samples had been filtered prior to receipt. All samples a pH less than 2 upon receipt, with the exception of samples 1404340-12 and -13. The samples were preserved with nitric acid to a pH less than 2 upon receipt. 4. The samples were prepared and analyzed based on SW-846, 3rd Edition procedures. The sample for TCLP analysis was processed through the TCLP leaching procedure based on method 1311. The leachate was then digested at a ten-fold dilution. For analysis by ICP-MS, the water samples were digested following method 3005A and the current revision of SOP 806. The soil samples were digested following method 3050B and SOP 806 Rev. 15. The leachate was digested following method 3010A and the current revision of SOP 806. For analysis by Cold Vapor AA (CVAA), the leachate sample and the water samples were digested following method 7470A and the current revision of SOP 812. The soil samples were digested following method 7471A and the current revision of SOP 812. 5. Analysis by ICP-MS followed method 6020A and the current revision of SOP 827. Leachate and water analysis by CVAA followed method 7470A and the current revision of SOP 812. Soil analysis by CVAA followed method 7471A and the current revision of SOP 812. Addendum 1 - 8468 CM/GC for Poudre River Whitewater Park Page 196 of 441 6. All standards and solutions are NIST traceable and were used within their recommended shelf life. 7. The samples were prepared and analyzed within the established hold times. All in house quality control procedures were followed, as described below. 8. General quality control procedures. „ A preparation (method) blank and laboratory control sample were digested and analyzed with the samples in each digestion batch. „ The preparation (method) blank associated with each digestion batch was below the reporting limit for the requested analytes. „ All laboratory control sample criteria were met. „ All initial and continuing calibration blanks were below the reporting limit for the requested analytes. „ All initial and continuing calibration verifications were within the acceptance criteria for the requested analytes. „ The interference check samples associated with Method 6020A were analyzed. 9. Matrix specific quality control procedures. Sample 1404340-19 was designated as the quality control sample for the ICP-MS leachate analysis. Per method requirements, matrix QC was performed for the remaining analyses. Since a sample from this order number was not the selected quality control (QC) sample, matrix specific QC results are not included in this report. Similarity of matrix and therefore relevance of the QC results should not be automatically inferred for any sample other than the native sample selected for QC. „ A matrix spike and matrix spike duplicate were digested and analyzed with the ICP-MS leachate batch. All acceptance criteria for accuracy were met. „ A sample duplicate and matrix spike duplicate were digested and analyzed with the ICP- MS leachate batch. All acceptance criteria for precision were met. „ A serial dilution was analyzed with the ICP-MS leachate batch. All acceptance criteria were met. 10. It is a standard practice that samples for ICP-MS are analyzed at a dilution.

An explanatory note may be included in the narrative. M - Duplicate injection precision was not met. N - Spiked sample recovery not within control limits. A post spike is analyzed for all ICP analyses when the matrix spike and or spike duplicate fail and the native sample concentration is less than four times the spike added concentration. Z - Spiked recovery not within control limits. An explanatory note may be included in the narrative. * - Duplicate analysis (relative percent difference) not within control limits. S - SAR value is estimated as one or more analytes used in the calculation were not detected above the detection limit.

This report consists of 7 soil samples. The samples were received intact by ALS on 04/18/14 at 8.2o and 04/21/14 at 15.4o Celsius. 2. The samples were prepared and analyzed according to SW-846, 3rd Edition procedures based on Method SW-9071 and utilizing the current revision of SOP 640. 3. The samples were prepared and analyzed within the established hold times. 4. The method blank associated with this project was below the reporting limit for oil and grease. 5. All laboratory control sample and laboratory control sample duplicate recoveries and RPDs were within the acceptance criteria. 6. Sample 1404340-3 was designated as the quality control sample for this analysis. Similarity of matrix and therefore relevance of the QC results should not be automatically inferred for any sample other than the native sample selected for QC. A matrix spike and matrix spike duplicate were prepared and analyzed with this batch. All acceptance criteria for precision and accuracy were met. Addendum 1 - 8468 CM/GC for Poudre River Whitewater Park Page 231 of 441 Addendum 1 - 8468 CM/GC for Poudre River Whitewater Park Page 232 of 441 ALS Data Qualifier Flags Chromatography and Mass Spectrometry U or ND: This flag indicates that the compound was analyzed for but not detected. J: This flag indicates an estimated value. This flag is used as follows : (1) when estimating a concentration for tentatively identified compounds (TICs) where a 1:1 response is assumed; (2) when the mass spectral and retention time data indicate the presence of a compound that meets the volatile and semivolatile GC/MS identification criteria, and the result is less than the reporting limit (RL) but greater than the method detection limit (MDL); (3) when the data indicate the presence of a compound that meets the identification criteria, and the result is less than the RL but greater than the MDL; and (4) the reported value is estimated. B: This flag is used when the analyte is detected in the associated method blank as well as in the sample. It indicates probable blank contamination and warns the data user. This flag shall be used for a tentatively identified compound (TIC) as well as for a positively identified target compound. E: This flag identifies compounds whose concentration exceeds the upper level of the calibration range.

This report consists of five water samples. The samples were received intact at 9.0°C by ALS on 04/22/14. The water samples were free of headspace prior to analysis. Samples 1404376-4, -6 and -11, provided for volatiles, had a pH > 2 at the time of analysis. All other water samples had a pH < 2 at the time of analysis. 2. The sample was prepared according to SW-846, 3rd Edition procedures. Specifically, the water samples were prepared using purge and trap procedures based on Method 5030C. 3. The samples were analyzed using GC/MS with an RTX-624, RTX-VMS, or equivalent capillary column according to the current revision of SOP 525 based on SW-846 Method 8260. All positive results were quantitated against the initial calibration standards using the internal standard technique. The identification of positive results was achieved by a comparison of the retention time and mass spectrum of the sample versus the daily calibration standard. 4. All criteria for the initial calibration were met. 5. All initial calibrations are verified by comparing a second source standard calibration verification (ICV) against the calibration curve. All criteria for initial calibration verification were met. 6. All compounds in the continuing calibration verification had a %D of less than 20% with the following exceptions: Bromomethane and chloroethane were high. These compounds were not detected in the associated samples. Bromoform and 1,2-dibromo-3-chloropropane were low. The daily reporting limit verification standard (RVS) indicates that there was adequate sensitivity to detect bromoform (1ppb= 102% recovery) and 1,2-dibromo-3-chloropropane (1ppb=152% recovery) at the applicable quantitation limit. These compounds were not detected in the associated samples.

J: This flag indicates an estimated value. This flag is used as follows : (1) when estimating a concentration for tentatively identified compounds (TICs) where a 1:1 response is assumed; (2) when the mass spectral and retention time data indicate the presence of a compound that meets the volatile and semivolatile GC/MS identification criteria, and the result is less than the reporting limit (RL) but greater than the method detection limit (MDL); (3) when the retention time data indicate the presence of a compound that meets the GC identification criteria, and the result is less than the RL but greater than the MDL; and (4) the reported value is estimated. B: This flag is used when the analyte is detected in the associated method blank as well as in the sample. It indicates probable blank contamination and warns the data user. This flag shall be used for a tentatively identified compound (TIC) as well as for a positively identified target compound. E: This flag identifies compounds whose concentration exceeds the upper level of the calibration range. A: This flag indicates that a tentatively identified compound is a suspected aldol- condensation product. X: This flag indicates that the analyte was diluted below an accurate quantitation level. *: This flag indicates that a spike recovery is equal to or outside the control criteria used. +: This flag indicates that the relative percent difference (RPD) equals or exceeds the control criteria. G: This flag indicates that a pattern resembling gasoline was detected in this sample. H: This flag indicates that the fuel pattern was in the heavier end of the retention time window for the analyte of interest. L: This flag indicates that the fuel pattern was in the lighter end of the retention time window for the analyte of interest. Z: This flag indicates that a significant fraction of the reported result did not resemble the patterns of any of the following petroleum hydrocarbon products: gasoline JP-8 diesel mineral spirits motor oil Stoddard solvent bunker C Addendum 1 -

This report consists of 10 water samples. The samples were received intact at 9.0°C by ALS on 04/22/14. 2. These samples were prepared and analyzed according to SW-846, 3rd Edition procedures. Specifically, the water samples were extracted using continuous liquid-liquid extractors, according to SW-846 Method 3520C, utilizing the current revision of SOP 617. 3. The extracts were analyzed using GC/MS with a DB-5MS capillary column according to the current revision of SOP 506 based on SW-846 Method 8270D. All positive results were quantitated against the initial calibration standards using the internal standard technique. The identification of positive results was achieved by a comparison of the retention time and mass spectrum of the sample versus the daily calibration standard. 4. All initial calibration criteria were met. If average response factors were used in the initial calibration, %RSD was ≤20%. If linear or higher order regression calibrations were used in the initial calibration, the coefficient of determination (r2) ≥0.99. 5. All initial calibration standards are verified by comparing a second source standard initial calibration verification (ICV) against the calibration curve. All target compounds in the second source verification had a %D ≤30%. 6. All compounds in each of the daily (continuing) calibration verifications were within 20%D with the exception of dibenzo(a,h)anthracene which was high. This compound was not detected in the associated samples. 7. All method blank criteria were met. 8. All laboratory control sample and laboratory control sample duplicate recoveries and RPDs were within the acceptance criteria.

J: This flag indicates an estimated value. This flag is used as follows: (1) when estimating a concentration for tentatively identified compounds (TICs) where a 1:1 response is assumed; (2) when the mass spectral and retention time data indicate the presence of a compound that meets the volatile and semivolatile GC/MS identification criteria, and the result is less than the reporting limit (RL) but greater than the method detection limit (MDL); (3) when the retention time data indicate the presence of a compound that meets the GC identification criteria, and the result is less than the RL but greater than the MDL; and (4) the reported value is estimated. B: This flag is used when the analyte is detected in the associated method blank as well as in the sample. It indicates probable blank contamination and warns the data user. This flag shall be used for a tentatively identified compound (TIC) as well as for a positively identified target compound. E: This flag identifies compounds whose concentration exceeds the upper level of the calibration range. A: This flag indicates that a tentatively identified compound is a suspected aldol-condensation product. X: This flag indicates that the analyte was diluted below an accurate quantitation level. *: This flag indicates that a spike recovery is equal to or outside the control criteria used. +: This flag indicates that the relative percent difference (RPD) equals or exceeds the control criteria.

This report consists of 1 TCLP sample and 3 water samples. 2. The samples were received intact at 9.0°C by ALS on 04/22/14. 3. The water samples were to be analyzed for dissolved metals. The samples had been filtered prior to receipt. All samples a pH less than 2 upon receipt, with the exception of sample 1404376-4. The sample was preserved with nitric acid to a pH less than 2 upon receipt. 4. The samples were prepared and analyzed based on SW-846, 3rd Edition procedures. The sample for TCLP analysis was processed through the TCLP leaching procedure based on method 1311. The leachate was then digested at a ten-fold dilution. For analysis by ICP-MS, the water samples were digested following method 3005A and the current revision of SOP 806. The leachate was digested following method 3010A and the current revision of SOP 806. For analysis by Cold Vapor AA (CVAA), the samples were digested following method 7470A and the current revision of SOP 812. 5. Analysis by ICP-MS followed method 6020A and the current revision of SOP 827. Analysis by CVAA followed method 7470A and the current revision of SOP 812. 6. All standards and solutions are NIST traceable and were used within their recommended shelf life. 7. The samples were prepared and analyzed within the established hold times. Addendum 1 - 8468 CM/GC for Poudre River Whitewater Park Page 295 of 441 All in house quality control procedures were followed, as described below. 8. General quality control procedures. „ A preparation (method) blank and laboratory control sample were digested and analyzed with the samples in each digestion batch. „ The preparation (method) blank associated with each digestion batch was below the reporting limit for the requested analytes. „ All laboratory control sample criteria were met. „ All initial and continuing calibration blanks were below the reporting limit for the requested analytes. „ All initial and continuing calibration verifications were within the acceptance criteria for the requested analytes. „ The interference check samples associated with Method 6020A were analyzed. 9. Matrix specific quality control procedures. Sample 1404376-12 was designated as the quality control sample for the ICP-MS leachate analysis. Sample 1404376-4 was designated as the quality control sample for the mercury water analysis. Per method requirements, matrix QC was performed for the ICP-MS water analysis and also the mercury leachate analysis. Since a sample from this order number was not the selected quality control (QC) sample, matrix specific QC results are not included in this report. Similarity of matrix and therefore relevance of the QC results should not be automatically inferred for any sample other than the native sample selected for QC. „ A matrix spike and matrix spike duplicate were digested and analyzed with each batch indicated above. All acceptance criteria for accuracy were met. „ A sample duplicate and matrix spike duplicate were digested and analyzed with each batch indicated above. All acceptance criteria for precision were met. „ A serial dilution was analyzed with the ICP-MS leachate batch. All acceptance criteria were met with the following exception: Analyte Sample ID Barium 1404376-12L The native sample result is flagged for serial dilution failure. 10. It is a standard practice that samples for ICP-MS are analyzed at a dilution. Addendum 1 - 8468 CM/GC for Poudre River Whitewater Park Page 296 of 441 Addendum 1 - 8468 CM/GC for Poudre River Whitewater Park Page 297 of 441 Inorganic Data Reporting Qualifiers The following qualifiers are used by the laboratory when reporting results of inorganic analyses. • Result qualifier -- If the analyte was analyzed for but not detected a “U” is entered. • QC qualifier -- Specified entries and their meanings are as follows: E - The reported value is estimated because of the presence of interference. An explanatory note may be included in the narrative. M - Duplicate injection precision was not met. N - Spiked sample recovery not within control limits. A post spike is analyzed for all ICP analyses when the matrix spike and or spike duplicate fail and the native sample concentration is less than four times the spike added concentration. Z - Spiked recovery not within control limits. An explanatory note may be included in the narrative. * - Duplicate analysis (relative percent difference) not within control limits. S - SAR value is estimated as one or more analytes used in the calculation were not detected above the detection limit.

J: This flag indicates an estimated value. This flag is used as follows : (1) when estimating a concentration for tentatively identified compounds (TICs) where a 1:1 response is assumed; (2) when the mass spectral and retention time data indicate the presence of a compound that meets the volatile and semivolatile GC/MS identification criteria, and the result is less than the reporting limit (RL) but greater than the method detection limit (MDL); (3) when the data indicate the presence of a compound that meets the identification criteria, and the result is less than the RL but greater than the MDL; and (4) the reported value is estimated. B: This flag is used when the analyte is detected in the associated method blank as well as in the sample. It indicates probable blank contamination and warns the data user. This flag shall be used for a tentatively identified compound (TIC) as well as for a positively identified target compound. E: This flag identifies compounds whose concentration exceeds the upper level of the calibration range. A: This flag indicates that a tentatively identified compound is a suspected aldol-condensation product. X: This flag indicates that the analyte was diluted below an accurate quantitation level. *: This flag indicates that a spike recovery is outside the control criteria. +: This flag indicates that the relative percent difference (RPD) exceeds the control criteria.

This report consists of 1 water sample. 2. The sample was received cool and intact by ALS on 04/22/14. 3. The sample was carried through the vapor generation procedure for reactive cyanide and reactive sulfide as described in chapter seven of USEPA SW-846 (July 1985). EPA has formally withdrawn their guidance for this method, as it is likely to underestimate the sample’s potential to liberate free cyanide and sulfide under waste management conditions. A copy of the EPA memo withdrawing the method guidance can be provided upon request. Released cyanide was determined colorimetrically according to Method 9014. Released sulfide was determined by iodometric titration according to Method 9030. 4. The sample was prepared for analysis based on SW-846, 3rd Edition procedures. 5. The sample was analyzed following SW-846 procedures for the current revisions of the following SOPs and methods: Analyte Method SOP # Reactive cyanide SW-846 Chap. 7, Sec. 3.1 1112 Reactive sulfide SW-846 Chap. 7, Sec. 3.2 1112 pH 9040C 1126 6. All standards and solutions were used within their recommended shelf life. 7. The sample was prepared and analyzed within the established hold time for each analysis. All in house quality control procedures were followed, as described below. 8. General quality control procedures.
