Introduction A.1. Project Description A.1.a. Proposed Construction This Geotechnical Evaluation Report addresses the proposed Minnesota Autism Center(MAC) Building on the undeveloped property located at 2100 Silver Bell Drive in Eagan, Minnesota.The project will include a one-level building with supporting site improvements.Additional project details are listed below in Table 1. Ryan Companies US, Inc. (Ryan)is managing and building the project for MAC. Table 1. Project Details Feature Description Site area (acres) 3.9 acres Building(square feet) Approximately 18,680 square feet Above grade levels One Below grade levels None Elevations(ft) FFE—799.25 Columns—200 Maximum column and wall loads(kips) Walls-8 per lineal foot (assumed) Cuts or fills for building Fills 0 to 10 feet • Automobile parking lot with light duty pavement Pavement details • Drive lanes and truck areas with heavy duty pavement • Estimated ESALs 100,000(20-year design)for heavy duty and 30,000(20-year design)for light duty • New stormwater basin in east corner with bottom elevation near 780 Stormwater/utility details • New stormwater basin in southwest corner of site with bottom elevation near 785 • New below grade utilities up to 10 feet below grade • New modular block retaining wall along south side of site with Additional site details wall heights up to 10 feet • Non-paved playground area to be located on the south side of the building BRAUN INTERTEC Ryan Companies US, Inc. Project B1610208 February 13, 2017 Page 2 We have attempted to describe our understanding of the project to the extent it was reported to us by the design team. Depending on the extent of available information, assumptions may have been made based on our experiences with similar projects. If we have not correctly recorded or interpreted the project details,we should be notified. New or changed information could require additional evaluation, analyses and/or recommendations. A.1.b. Site Details The project site(Dakota County Property ID 101667501010) is currently an undeveloped parcel between Silver Bell Road and TH 13 in Eagan, Minnesota.The site is lightly to moderately vegetated. Overall site elevations range from approximately 800 (along Silver Bell Road)to near 780(along the TH 13 ROW), with elevations generally sloping down toward the south.Several small fill piles are also present along the western and eastern portions of the site. To our knowledge the site has not been historically developed; however,the historical area photographs and available site information indicate the site has been subject to past grading.The initial grading appears to have occurred in the 1950s and 1960s and has been primarily associated with sand and gravel mining. In the early 2000s additional grading occurred, likely related to initial development of a warehouse facility(that was not completed) as indicated by the previous geotechnical report and grading information referenced in Section A.3. A.2. Purpose The purpose of this geotechnical evaluation was to characterize subsurface geologic conditions at selected exploration locations,evaluate their impact and provide recommendations for the design and construction of the proposed MAC facility. A.3. Background Information and Reference Documents To facilitate our evaluation,we were provided with or reviewed the following information or documents: • Site,grading and utility plans provided by Ryan Companies.An electronic copy of this grading plan file was used to prepare the attached Soil Boring Location Sketch. • Historic site survey, dated October 15, 1996, and a Grading, Drainage and Erosion Control Plan (not dated) prepared by Schoell and Madson, Inc. BRAUN INTERTEC 1 Ryan Companies US, Inc. Project B1610208 February 13, 2017 Page 3 • A Report of Geotechnical Exploration and Review dated October 15, 1996, prepared by American Engineering and Testing, Inc.The report included 9 standard penetration borings performed as part of the site development and grading in the 2000s. • Phase I ESA prepared for the project by Braun Intertec(Project B1610458). A.4. Scope of Services Our scope of services for this project was performed in accordance with the Project Agreement between Ryan Companies US, Inc. and Braun Intertec, signed and dated October 26, 2016.Tasks completed in accordance with our authorized scope of services are described below. • Reviewing previous available geotechnical information. • Selecting and staking the soil boring locations and determining ground surface elevations at these locations.The surface elevations and locations for the borings and test pits were acquired with GPS technology through the use of the State of Minnesota's permanent GPS base station network.The approximate locations are shown on the Soil Boring Location Sketch included in the Appendix. • Coordinating the locating of underground public utilities near the boring locations. • Performing 15 standard penetration test(SPT) borings(denoted as ST-1 to ST-15)with an off- road vehicle-mounted drill rig to depths of 10 to 20 feet below grade. • Classifying the recovered samples and preparing boring logs. • Conducting a limited laboratory testing program to aid in soil classification and evaluation of engineering properties. • Performing engineering analysis,formulating recommendations,and submitting a geotechnical evaluation report containing logs of the borings, laboratory tests, and recommendations for design of foundations, interior and exterior slabs on grade, utilities, site improvements and pavements. Several test pits were also later excavated as part of the Phase II ESA performed for Ryan Companies.The test pits denoted as TP-2 to TP-4,TP-6 and TP-7 were located near the proposed building pad and were observed and documented by a geotechnical engineer.The results of the test pit observations are included within the Appendix and are referenced within this report. BRAUN INTERTEC Ryan Companies US, Inc. Project B1610208 February 13, 2017 Page 4 B. Results B.1. Geologic Overview We based the geologic origins used in this report on the soil types, in-situ and laboratory testing,and available common knowledge of the geological history of the site. Because of the complex depositional history,geologic origins can be difficult to ascertain. We did not perform a detailed investigation of the geologic history for the site. B.2. Boring Results B.2.a. Soil Profile The general soil profile encountered at the exploration locations consisted of a variable layer of fill over glacial deposits.Table 2 provides a summary of the boring results. Please refer to the Log of Boring sheets in the Appendix for additional details. Table 2.Soil Profile Summary Range of Soil Type- Penetration Strata ASTM Classification Resistances Details Silty Sand(SM) • Dark brown to black Topsoil fill Clayey Sand (SC) NA • 1/2 to 4 feet thick,typically less than 1 1/2 feet Lean Clay(CL) • Present to depths of 4 to 11 feet below grade at Poorly Graded Sand with 4 to 58 BPF* all locations Silt(SP-SM) (BPF exceeded • Fill was mixed,but primarily SM Fill Silty Sand(SM) 8 for all tests • Brown to dark brown,moist to wet Clayey Sand(SC) below 2 1/2 • Variable gravel,cobbles and boulders Sandy Silt(ML) feet) • Typically non-organic Lean Clay(CL) • Debris not observed within borings or test pits; some concrete visible at ground surface Poorly Graded Sand (SP) • Primarily glacial till and outwash Glacial Poorly Graded Sand with 5 to 41 BPF* • Brown to reddish brown deposits Silt(SP SM) • Variable amounts of gravel,cobbles and boulders Silty Sand (SM) *BPF—Blows per foot. BRAUN INTERTEC Ryan Companies US, Inc. Project B1610208 February 13, 2017 Page 5 B.2.b. Groundwater Table 3 summarizes the depths where we observed groundwater;the attached Log of Boring sheets in the Appendix also include this information and additional details. Table 3.Groundwater Summary Measured or Estimated Corresponding Surface Depth to Groundwater Groundwater Elevation Location Elevation (ft) (ft) ST-11 776.9 7 770 ST-12 783.1 17 766 ST-14 778.7 7 771 1/2 ST-15 777.3 9 768 1/2 Groundwater was generally observed within the southeastern portion of the site,where surface elevations are lower.At the time of our observation,the groundwater surface elevation appeared to be near elevation 770. Project planning should expect groundwater will fluctuate in relation to annual and seasonal conditions. B.3. Laboratory Test Results Laboratory tests performed on recovered samples included moisture content and sieve analysis. Laboratory test results are included on the log of boring sheets, across from the associated sample. Of note, moisture content test results indicate the on-site sands are generally near to below their estimated optimum moisture contents,while the clayey soils ranged from below to slightly above their estimated moisture contents. C. Recommendations C.1. Design and Construction Discussion C.1.a. Building Support The soil profile below the proposed building consisted of about 4 to 11 feet of previously placed fill over glacial soils. Below the topsoil and several soil stockpiles (near Borings ST-1 and ST-2),the fill is relatively uniform,generally does not contain organic material or debris, and appears to be moderately to well compacted. Based on the available information, it appears the original mining in the 1950s and 1960s BRAUN INTERTEC ■ Ryan Companies US, Inc. Project B1610208 February 13,2017 Page 6 generally consisted of borrow or removal operations(of sand and gravel)with limited replacement of removed material.Then in the late 1990s or early 2000s, a large portion of the middle of the site was graded to near elevation 790 for a warehouse facility that subsequently was not constructed.The proposed MAC building generally appears to be located within this graded area. Overall the fill generally appears to have been placed in a controlled manner suitable for support of the proposed MAC building, with the exception of soil stockpiles along the western edge of the site (near ST-1, ST-2,TP-2 and TP-3). However, since the fill is undocumented to our knowledge,there is a risk of settlement associated with supporting the proposed structure on the fill due to the unknown nature of the fill placement.As discussed with Ryan, it is our opinion this risk appears limited and reasonable to be assumed and outweighs the cost of removing the fill. If the owner is unwilling to assume this risk,the fill should be removed down to the glacial soils and replaced with documented engineered fill. On-site observations and evaluation by the geotechnical engineer during mass grading and construction can help further reduce this risk.As discussed with Ryan,we understand the fill will generally be evaluated in the field and left in place and the recommendations provided within the remainder of this report support this option.The test pit observations indicated the fill was similar in content and consistency as indicated by the soil borings. C.1.b. Building Pad Preparation For building pad preparation,we recommend stripping of the topsoil fill and areas of soft/loose fill soils. Based on the borings and test pits, it appears some of the fill within the upper 2 to 3 feet was disturbed by freeze/thaw action since placement or was placed after the initial mass grading and was not adequately compacted. Fill stripping should include removal of topsoil and on-site stockpiles.After stripping,the exposed surface should be surface compacted and proofrolled to identify any additional areas of beyond those identified at borings. After subgrade excavation,engineered fill can be placed as needed to establish building subgrades. We understand the site will require imported soils to achieve site grades. We recommend imported soils for the building pad consist of relatively clean sands for uniformity with on-site soils material and design and construction benefits. C.1.c. Reuse of On-Site soils The on-site soils generally consisted of mixed sands, including poorly graded sand, silty sand and clayey sand.The on-site soils can be considered for reuse assuming they can be properly compacted; the on-site sands will likely require moisture conditioning by the contractor to achieve the recommended compaction levels.We recommend against reusing lean clay and silt soils as structural fill below the proposed building due to difficulty in moisture conditioning and recompaction. BRAUN INTERTEC Ryan Companies US, Inc. Project B1610208 February 13, 2017 Page 7 C.1.d. Disturbance of On-Site Soils Near surface soils generally consist of silty or clayey sand;the project team should note these soils are susceptible to disturbance due to repeated construction traffic. Disturbance of these soils may cause areas that were previously prepared or suitable for pavement or structure support to become unstable and require addition moisture conditioning, compaction, and/or subcutting. Care should be taken to avoid disturbing the soils. C.1.e. Groundwater Impacts We anticipate groundwater will generally not building or site improvement construction.The potential exception would be if stormwater improvements or utilities extend near elevation 770. C.2. Site Grading and Subgrade Preparation C.2.a. Building Pad Excavation and Subgrade Evaluation For building pad preparation, we recommend removing the topsoil, other organic soils,and loose/soft/disturbed fill from below the proposed building pad and oversize area. After removing the unsuitable soils and prior to placing fill materials necessary to achieve finished grades, we recommend the exposed subgrade should be scarified to a minimum depth of 8 inches, moisture conditioned to within 1 percent below to 3 percent above their optimum moisture content and compacted with a self-propelled vibratory compactor to at least 98 percent of the standard Proctor maximum dry density(ASTM International 698). A geotechnical engineer should observe all excavation subgrades and surface compaction activities to help evaluate the suitability of the exposed subgrades and the need for further stabilization prior to placing fill needed to achieve finished elevations. If present,we also recommend removal of any existing utilities and associated trench fill from below the proposed building pad. Table 4 provides the anticipated soil correction depths at the soil boring and test pit locations within or near the proposed building. Please note that the excavation depths in this table are based on removing only topsoil fill and existing fill identified by our borings to be poorly compacted,and does not include removal of all existing fill, as discussed in Section C.1.a of this report. Excavation depths will vary between the boring and test pit locations. Portions of the excavations may also be deeper than indicated by the borings. Contractors should also be prepared to extend excavations if unstable or additional fill soils are encountered. BRAUN INTERTEC Ryan Companies US, Inc.

C.2.b. Retaining Wall Subgrade Preparation We recommend the subgrade for the proposed modular block retaining wall be prepared in accordance with Section C.2.a and the retaining wall specifications. For walls with reinforced fill,we recommend the lateral oversizing extend outward and downward from the back of the fill reinforcement. C.2.c. Pavement and Exterior Slab Subgrade Preparation We recommend the following general steps for pavement and exterior slab subgrade preparation. Note that project planning may need to require additional subcuts to limit frost heave. 1. Prior to placing fill to attain proposed pavement subgrades, strip unsuitable soils consisting of topsoil,organic soils,vegetation,existing structures and pavements from the area. 2. Have a geotechnical representative observe the excavated subgrade to evaluate if additional subgrade improvements are necessary. 3. Slope subgrade soils to areas of sand or drain tile where accumulating water can be removed. BRAUN I NTE BTEC Ryan Companies US, Inc. Project B1610208 February 13,2017 Page 9 4. Scarify, moisture condition and surface compact the subgrade with at least four passes of a large roller with a minimum drum diameter of 3 1/2 feet or as recommended by the geotechnical representative in the field. 5. Place pavement fill to grade and compact in accordance with Section C.2.g.to bottom of pavement and exterior slab section. 6. Proofroll the pavement or exterior slab subgrade as described below. After preparing the subgrade as described above and prior to the placement of the aggregate base,we recommend proofrolling the subgrade soils with a fully loaded tandem-axle truck. We also recommend having a geotechnical representative observe the proofroll.Areas that fail the proofroll likely indicate soft or weak areas that will require additional soil correction work to support pavements. The contractor should correct areas that display excessive yielding or rutting in excess of 1 to 2 inches during the proofroll. Possible options for subgrade correction include moisture conditioning and recompaction, subcutting and replacement with soil or crushed aggregate, chemical stabilization and/or geotextiles. We recommend performing a second proofroll after the aggregate base material is in place, and prior to placing bituminous or concrete pavement. To provide lateral support to replacement backfill, additional required fill and the structural loads they will support,we recommend oversizing(widening)the excavations 1 foot horizontally beyond the outer edges of the building perimeter footings,or pavement limits,for each foot the excavations extend below bottom-of-footing or pavement subgrade elevations(1H:1V oversizing). C.2.d. Excavation Oversizing When removing unsuitable materials below structures or pavements,we recommend the excavation extend outward and downward at a slope of 1H:1V(horizontal:vertical) or flatter. See Figure 1 for an illustration of excavation oversizing. BRAUN I NTE RTEC Ryan Companies US, Inc. Project B1610208 February 13,2017 Page 10 Figure 1.

Excavated Slopes Based on the borings,we anticipate on-site soils in excavations will consist primarily of sandy soils.These soils are typically considered Type C Soil under OSHA(Occupational Safety and Health Administration) guidelines. OSHA guidelines indicate unsupported excavations in Type C soils should have a gradient no steeper than 1 1/2H:1V.Slopes constructed in this manner may still exhibit surface sloughing. OSHA requires an engineer to evaluate slopes or excavations over 20 feet in depth. An OSHA-approved qualified person should review the soil classification in the field. Excavations must comply with the requirements of OSHA 29 CFR, Part 1926, Subpart P, "Excavations and Trenches."This document states excavation safety is the responsibility of the contractor.The project specifications should reference these OSHA requirements. BRAUN INTERTEC Ryan Companies US, Inc. Project B1610208 February 13,2017 Page 11 C.2.f. Excavation Dewatering We do not anticipate groundwater will generally be encountered during on-site excavations; however, if present we recommend removing groundwater from the excavations. Dewatering within the high permeability soils(e.g., sands)from within the excavation with conventional pumps has the potential to loosen the soils, due to upward flow. If dewatering is required, a well contractor should develop a dewatering plan;the design team should review this plan. C.2.g. Compaction and Fill Materials Table 5 below contains our recommendations for fill materials. Table 5.

We recommend spreading fill in loose lifts no thicker than 12 inches. Smaller equipment may require thinner lifts to meet specified density.We recommend compacting fill in accordance with the criteria presented below in Table 6.The relative compaction of utility fill should be evaluated based on the requirements of the structures or pavement above the utility line, and vertical proximity to that structure. BRAUN INTERTEC Ryan Companies US, Inc. Project B1610208 February 13,2017 Page 12 If site grading and construction is anticipated during cold weather,snow and ice should be removed from cut and fill areas prior to additional grading. No fill should be placed on frozen subgrades. No frozen soils should be used as fill. Frost should not be allowed to penetrate below the footings.

BRAUN I NTE BTEC Ryan Companies US, Inc. Project B1610208 February 13, 2017 Page 13 C.4. Interior Slabs C.4.a. Subgrade Support and Design The floor slab subgrades are anticipated to consist of engineering sand fill (SP,SP-SM and SM) suitable for slab support. We recommend using a modulus of subgrade reaction, k value, of 200 pounds per square inch per inch of deflection (pci)to design the slabs. We also recommend a minimum of 6 inches of compacted crushed gravel road base be placed immediately beneath the interior floor slabs. With the addition of the 6 inches of compacted crushed gravel, it is our opinion that the modulus may be increased by 50 pci. The aggregate base will help provide a stable working platform during construction. We recommend that the stabilizing aggregate consist of crushed rock meeting the requirements of MnDOT Specification 3138 for Class 5. No material containing recycled bituminous should be used under interior slabs.The crushed gravel base should be compacted to at least 98 percent of its Standard Proctor maximum dry density. C.4.b. Moisture Vapor Protection Excess transmission of water vapor could cause floor dampness,certain types of floor bonding agents to separate, or mold to form under floor coverings. If project planning includes using floor coverings or coatings,we recommend placing a vapor retarder or vapor barrier immediately beneath the slab.We also recommend consulting with floor covering manufacturers regarding the appropriate type, use and installation of the vapor retarder or barrier to preserve warranty assurances. C.S. Pavements and Exterior Slabs C.S.a. Design Sections After site grading, we anticipate the pavement subgrades will generally consist of poorly graded sand, silty sand and clayey sand. For pavement design,we recommend using an assumed R-value of 30. For concrete pavement design,we recommend a modulus of subgrade reaction (k)of 150 pci. Table 8 provides our recommendations for pavement design.The light duty pavement section is recommended for automobile parking areas and the heavy duty section is recommended for drive lanes and any truck parking areas.The concrete section is provided as an alternate for loading dock,truck parking or heavy duty pavement areas.The concrete section will provide greater resistance to static loading. BRAUN INTERTEC Ryan Companies US, Inc. Project B1610208 February 13, 2017 Page 14 Table 8. Recommended Bituminous(and Concrete)Pavement Sections Heavy Duty Use Light Duty Heavy Duty (concrete) Minimum asphalt 3 1/2 4 thickness(inches) Minimum concrete 6 thickness(inches) Minimum aggregate base 6 8 4 thickness(inches) These designs assume edge support. For concrete pavement,the aggregate base is to provide a constructible base for placement, reduces faulting, and helps dissipate loads.Appropriate mix designs, panel sizing,jointing, doweling and edge reinforcement are critical to performance of concrete pavements. For bituminous pavements, long-term performance will depend on appropriate materials selection and construction techniques. C.5.b. Materials and Compaction We recommend specifying crushed aggregate base meeting the requirements of MnDOT Specification 3138 for Class 5.We recommend the bituminous wear and base courses meet the requirements of Specifications 2360. For bituminous pavement design,we recommend the following mix designs for the wear and non-wear courses: SPWEB340E &SPNWB330B. We recommend that the aggregate base be compacted to a minimum of 100 percent of its maximum standard Proctor dry density. We recommend that the bituminous pavement be compacted to at least 92 percent of the maximum theoretical Rice density. We recommend specifying concrete for pavements that has a minimum 28-day compressive strength of 4,500 psi, and a modulus of rupture (Mr)of at least 600 psi. We also recommend Type I cement meeting the requirements of ASTM C 150.We recommend specifying 5 to 7 percent entrained air for exposed concrete to provide resistance to freeze-thaw deterioration. We also recommend using a water/cement ratio of 0.45 or less for concrete exposed to deicers. BRAUN INTERTEC Ryan Companies US, Inc. Project B1610208 February 13, 2017 Page 15 C.5.c. Subgrade Drainage We recommend installing perforated drainpipes throughout pavement areas (not below existing structures) at low points and about catch basins and along the perimeter of pavement areas where adjacent surface grades will promote drainage towards the pavement.The drainpipes should be placed in small trenches slightly below the bottom of the aggregate base material. C.5.d. Performance and Maintenance The above pavement designs are based upon a 20-year performance life and a 35-year life for concrete. This is the amount of time before major reconstruction is anticipated.This performance life assumes maintenance, such as seal coating and crack sealing, is routinely performed.The actual pavement life will vary depending on variations in weather,traffic conditions and maintenance. It is common to place the base course of bituminous and then delay placement of wear course. If this approach is taken,the base course should be evaluated to determine if the base course alone has sufficient capacity to support the construction traffic without reducing long-term capacity. The ongoing performance of pavements is impacted by conditions under which the pavement is asked to perform.These conditions include the environmental conditions,the actual use conditions and the level of ongoing maintenance performed.With regard to bituminous pavements in particular, because of normal thermal expansion and contraction, it is not unusual to have cracking develop within the first few years of placement and for the cracking to continue throughout the life of the pavement. A regular maintenance plan should be developed for filling cracks in bituminous pavements to lessen the potential impacts for cold weather distress due to frost heave or warm weather distress due to wetting and softening of the subgrade. It is also not unusual for bituminous pavements to require a seal coat within the first 5 to 10 years to increase the long-term performance. C.6. Frost Protection C.6.a. General Silty and clayey sands will be present across areas of the site and will underlie all or some of the exterior slabs, as well as pavements. We consider these soils moderately to highly frost susceptible. Soils of this type can retain moisture and heave upon freezing. In general,this characteristic is not an issue unless these soils become saturated, due to surface runoff or infiltration,or are excessively wet in situ. Once frozen, unfavorable amounts of general and isolated heaving of the soils and the surface structures supported on them could develop.This type of heaving could affect design drainage patterns and the performance of exterior slabs and pavements, as well as any isolated exterior footings and piers. BRAUN INTERTEC Ryan Companies US, Inc. Project B1610208 February 13, 2017 Page 16 Note that general runoff and infiltration from precipitation are not the only sources of water that can saturate subgrade soils and contribute to frost heave. Roof drainage and irrigation of landscaped areas in close proximity to exterior slabs, pavements, and isolated footings and piers,contribute as well. C.6.b. Frost Heave Mitigation To address most of the heave related issues,we recommend setting general site grades and grades for exterior surface features to direct surface drainage away from buildings, across large paved areas and away from walkways. Such grading will limit the potential for saturation of the subgrade and subsequent heaving. General grades should also have enough "slope"to tolerate potential larger areas of heave, which may not fully settle after thawing. Even small amounts of frost-related differential movement at walkway joints or cracks can create tripping hazards. Project planning can explore several subgrade improvement options to address this condition. One of the more conservative subgrade improvement options to mitigate potential heave is removing any frost-susceptible soils present below the exterior slab areas down to a minimum depth of 5 feet below subgrade elevations. We recommend filling the resulting excavation with non-frost-susceptible fill. We also recommend sloping the bottom of the excavation toward one or more collection points to remove any water entering the fill.This approach will not be effective in controlling frost heave without removing the water. An important geometric aspect of the excavation and replacement approach described above is sloping the banks of the excavations to create a more gradual transition between the unexcavated soils considered frost susceptible and the excavation fill,which is not frost susceptible.The slope allows attenuation of differential movement that may occur along the excavation boundary.We recommend slopes that are 3H:1V, or flatter, along transitions between frost-susceptible and non-frost-susceptible soils. Figure 2 shows an illustration summarizing some of the recommendations. BRAUN INTERTEC Ryan Companies US, Inc. Project B1610208 February 13, 2017 Page 17 Figure 2.

Over the life of slabs and pavements,cracks will develop and joints will open up,which will expose the subgrade and allow water to enter from the surface and either saturate or perch atop the subgrade soils. This water intrusion increases the potential for frost heave or moisture-related distress near the crack or joint.Therefore,we recommend implementing a detailed maintenance program to seal and/or fill any cracks and joints.The maintenance program should give special attention to areas where dissimilar materials abut one another,where construction joints occur and where shrinkage cracks develop. C.7. Retaining Walls The following comments and recommendations may be used in retaining wall design and construction, however,final design responsibility will rest with the wall design engineer. Retaining wall designers should be informed of site features and utilities that would influence their design. Our scope of services did not include global stability analysis. If desired,we can provide global stability analysis of the proposed walls. C.7.a. Drainage Drainage behind the walls is critical. Unless a drainage composite is placed against the backs of the retaining walls,we recommend that fill placed within 2 horizontal feet of the walls consist of free BRAUN INTERTEC Ryan Companies US, Inc. Project B1610208 February 13,2017 Page 18 draining material in accordance with Table 5, Section C.2.g. If"clear"gravel only is used for drainage, a fabric separator may be needed to keep sand from washing into the gravel. Water within this zone should be removed and routed away from the wall and its foundation zone. Wall fill not capped with slabs or pavement should be capped with a low-permeability soil to limit the infiltration of surface drainage into the fill.Grades should also be sloped to divert water away from the walls and the reinforced zone. We recommend the wall designer be consulted if water is introduced to the area of the wall. C.7.b. Net Allowable Bearing Pressure We anticipate foundations for the proposed retaining wall will bear on engineered fill,or native glacial soils. For wall design purposes,we recommend foundations bearing on these materials be designed to exert a maximum soil bearing pressure of 2,500 pounds per square foot(psf).All foundation subgrades should be reviewed by a geotechnical engineer. We anticipate total settlement of the wall will not exceed 1 inch; however, we recommend additional settlement analysis be performed as part of final wall design. C.7.c. Selection, Placement and Compaction of Fill We recommend wall fill below the wall and in the reinforced zone behind the wall be selected, placed and compacted in accordance with Section C.2.g. We recommend fill be placed on level surfaces. Therefore, any fill placed on or against sloping ground should begin from the bottom of the slope where a level surface can be established and properly'keyed' into the slope. Keys should consist of a level bench excavated to a convenient width for the equipment used.This will provide a more stable fill condition and reduce the potential for slip surface to occur along the existing soil/new fill interface. We recommend a walk-behind compactor be used to compact the backfill placed within about 5 feet of the retaining walls. Further away than that,a self-propelled compactor can be used. C.7.d. Design Parameters We recommend stand-alone retaining walls be designed for the parameters provided in Table 9.We assumed stand-alone retaining wall will be allowed to rotate slightly and will be designed for active earth pressures. Assumed wet unit backfill weights,and internal friction angles are also provided. Consideration needs to be given for sloping backfill or other dead or live loads that are placed within a horizontal distance behind the walls that is equal to the height of the walls. Our design values also assume that the walls are drained so that water cannot accumulate behind the walls.The construction documents should clearly state what soils should be used for fill behind the walls. BRAUN INTERTEC Ryan Companies US, Inc. Project B1610208 February 13, 2017 Page 19 Table 9. Recommended Below-Grade Wall Design Parameters Equivalent Fluid Pressure, Wet Unit Weight Friction Angle Active Case* Retained Soil (pcf) (deg) (pcf) SP,SP SM 120 32 37 (Imported) SM,SC 125 28 45 (On-site Soils) *Based on Rankine model for soils in a region behind the wall extending at least 2 horizontal feet beyond the bottom outer edges of the wall footings and then rising up and away from the wall at an angle no steeper than 60 degrees from horizontal. Resistance to lateral earth pressures will be provided by passive resistance against the retaining wall footing, and by sliding resistance along the bottoms of the wall footing. We recommend assuming a passive pressure equal to 350 pcf and a sliding coefficient equal to 0.45.These values are un-factored. C.7.e. Global Factor of Safety In addition to other applicable stability and performance demonstrations,we recommend retaining wall design documents or submittals contain demonstrations of global stability with a minimum factor of safety against global failure of 1.5 or greater. C.B. Utilities C.8.a. Subgrade Stabilization Earthwork activities associated with utility installations located inside the building footprint should adhere to the recommendations in Section C.2.a. For exterior utilities,we anticipate the soils at typical invert elevations will be suitable for utility support. However, if construction encounters unfavorable conditions such as soft clay, organic soils or perched water at invert grades,the unsuitable soils may require some additional subcutting and replacement with sand or crushed rock to prepare a proper subgrade for pipe support. Project design and construction should not place utilities within the 1H:1V oversizing of foundations. C.8.b. Corrosion Potential A majority of the soil borings indicated the site predominantly consists of sandy soils. We consider these soils non-to slightly-corrosive to metallic conduits. If utilities extend through clay soils,we recommend bedding the utilities in sandy soil free of any clay lumps or constructing the utilities with non-corrosive materials. BRAUN INTERTEC Ryan Companies US, Inc. Project B1610208 February 13,2017 Page 20 C.9. Stormwater Improvements Based on the results of our borings,Table 10 below provides infiltration rates in accordance with the Minnesota Stormwater Manual for the two proposed stormwater basins. Higher infiltration rates may be determined based on field testing with Double Ring lnfiltrometer testing(ASTM D3385), however,these rates should be adjusted by the appropriate correction factor as provided for within the Minnesota Stormwater Manual or as allowed by the local watershed. We recommend the Minnesota Stormwater Manual should be consulted for further design best practices. Table 10. Recommended Design Infiltration Rates Basin Bottom Elevation Soil Type* Infiltration Rate* Southwest Basin 785 SM 0.45 CL/SM 0.06 East Basin 780 (SP/SP-SM soils present if (0.8 if SP/SP-SM soils overlying CL/SM removed) exposed) *In accordance with the Minnesota Stormwater Manual C.10. Equipment Support The recommendations included in the report may not be applicable to equipment used for the construction and maintenance of this project. Subgrade conditions in areas where it is intended to support shoring, scaffolding, cranes, pumps, lifts and other construction equipment should be evaluated prior to mobilization to determine if the exposed materials are suitable for equipment support,or if some form of subgrade improvement should first be performed. Consideration should be given to the effect that loads applied by such equipment may have on structures they bear on or surcharge- including pavements, buried utilities, below-grade walls, etc. We would be pleased to assist you in this evaluation. C.11. Construction Quality Control We recommend having the excavation and placement of fill within the building pad be placed under the direction of Special Inspections as provided in Chapter 17,Section 1704.7 of the International Building Code.This requires the observation of soil or bedrock conditions below fill or footings,to evaluate if excavations extend to the anticipated soils and if fill material meets requirements for type of fill and compaction condition of fill.This work should include evaluation of the subgrade, note the preparation of the subgrade such as surface compaction, excavation oversizing, placement procedures and materials used for fill, and compaction testing of the fill. BRAUN INTERTEC Ryan Companies US, Inc. Project B1610208 February 13,2017 Page 21 This work should be carried out under the direction of a licensed geotechnical engineer.The purpose of these special inspections is to evaluate whether the work is being carried out in accordance with the approved Geotechnical Report for the project. D. Procedures D.1. Penetration Test Borings The penetration test borings were drilled with an off-road vehicle-mounted core and auger drill equipped with hollow-stem auger.The borings were performed in accordance with ASTM D 1586. Penetration test samples were taken at 2 1/2-or 5-foot intervals.Actual sample intervals and corresponding depths are shown on the boring logs. D.2. Exploration Logs D.2.a. Log of Boring and Test Pit Sheets Log of Boring sheets for our penetration test and borings and auger borings are included in the Appendix. The logs identify and describe the geologic materials that were penetrated, and present the results of penetration resistance tests performed within them, laboratory tests performed on penetration test samples retrieved from them, and groundwater measurements. Strata boundaries were inferred from changes in the penetration test samples and the auger cuttings. The strata boundary depths are only approximate. The boundary depths likely vary away from the boring locations, and the boundaries themselves may also occur as gradual rather than abrupt transitions. The Appendix also includes Log of Test Pit sheets.The logs classify and describe the geologic materials exposed in the sidewalls and bottoms of the pits and depict groundwater measurements. D.2.b. Geologic Origins Geologic origins assigned to the materials shown on the logs and referenced within this report were based on: (1) a review of the background information and reference documents cited above, (2)visual classification of the various geologic material samples retrieved during the course of our subsurface exploration, (3) penetration resistance and other in-situ testing performed for the project, (4) laboratory test results, and (5) available common knowledge of the geologic processes and environments that have impacted the site and surrounding area in the past. BRAUN INTERTEC Ryan Companies US, Inc. Project B1610208 February 13, 2017 Page 22 D.3. Material Classification and Testing D.3.a. Visual and Manual Classification The geologic materials encountered were visually and manually classified in accordance with ASTM Standard Practice D 2488.A chart explaining the classification system is attached.Samples were placed in jars and returned to our facility for review and storage. D.3.b. Laboratory Testing The results of the laboratory tests performed on geologic material samples are noted on or follow the appropriate attached exploration logs.The tests were performed in accordance with ASTM procedures. D.4. Groundwater Measurements The drillers checked for groundwater as the penetration test borings were advanced, and again after auger withdrawal.The boreholes were then backfilled and patched with blacktop as noted on the boring logs. E. Qualifications E.1. Variations in Subsurface Conditions E.1.a. Material Strata Our evaluation,analyses and recommendations were developed from a limited amount of site and subsurface information. It is not standard engineering practice to retrieve material samples from exploration locations continuously with depth,and therefore strata boundaries and thicknesses must be inferred to some extent. Strata boundaries may also be gradual transitions, and can be expected to vary in depth, elevation and thickness away from the exploration locations. Variations in subsurface conditions present between exploration locations may not be revealed until additional exploration work is completed, or construction commences. If any such variations are revealed,our recommendations should be re-evaluated. Such variations could increase construction costs, and a contingency should be provided to accommodate them. BRAUN INTERTEC Ryan Companies US, Inc. Project B1610208 February 13, 2017 Page 23 E.1.b. Groundwater Levels Groundwater measurements were made under the conditions reported herein and shown on the exploration logs, and interpreted in the text of this report. It should be noted that the observation periods were relatively short, and groundwater can be expected to fluctuate in response to rainfall, flooding, irrigation,seasonal freezing and thawing, surface drainage modifications and other seasonal and annual factors. E.2. Continuity of Professional Responsibility E.2.a. Plan Review This report is based on a limited amount of information,and a number of assumptions were necessary to help us develop our recommendations. It is recommended that our firm review the geotechnical aspects of the designs and specifications, and evaluate whether the design is as expected, if any design changes have affected the validity of our recommendations, and if our recommendations have been correctly interpreted and implemented in the designs and specifications. E.2.b. Construction Observations and Testing It is recommended that we be retained to perform observations and tests during construction.This will allow correlation of the subsurface conditions encountered during construction with those encountered by the borings, and provide continuity of professional responsibility. E.3. Use of Report This report is for the exclusive use of the parties to which it has been addressed.Without written approval,we assume no responsibility to other parties regarding this report. Our evaluation, analyses and recommendations may not be appropriate for other parties or projects. E.4.

We understand the City of Eagan code requires the building to meet certain noise reduction levels based on the "Aircraft Noise Zone" established in the Metropolitan Council's 2040 Transportation Policy Plan. The noise reduction requirements apply to the roof, walls, windows and doors, as well as the mechanical systems that could allow noise to propagate to the interior. To demonstrate that the design meets the City requirements, project documentation must be reviewed to assure that the "plans and specifications adequately document the use of construction assemblies that meet or exceed the STC ratings required." ESI Engineering has been asked to evaluate the building design to determine if the code STC requirements are being met and provide recommendations to meet requirements if necessary. } > s—NeefoRd" 5 � Syed — ¢ g'••• ",,, f"7M w _..s 0 r Cy ' " * .r * a+'4 " 2100SINecBd Road' :`o Minnesota Autis -r , ,. * ".vb ty = r t1"1:.,,W° e riot �� *, a .n� •,_,, . � ��"� fie, «N - PROJECT SITIlk E r�`e� ..r '` N „...' „Crew Factory -' °. / ',...re\'' :It: -,-„1„4„..-'4; ,, . ,,,,::,6 '4.4511-i:e.C4.

The following lists the steps and logic used to determine the ratings and other requirements. 1 . Regulations that affect this project include the following: a. City of Eagan Code, Sec. 11.64 —ANZ —Aircraft Noise Zone Overlay District. b. Metropolitan Council 2040 Transportation Policy Plan, Appendix L: Aviation Land Use Compatibility Guidelines (Adopted January 14, 2015). c. Metropolitan Council Builders Guide: Mitigating Aircraft Noise in New Residential Construction (Dated March 2016). 2. The project site is located at 2100 Silver Bell Road, Eagan, Minnesota. According to Figure L-1 in the Metropolitan Council 2040 Transportation Policy Plan (2040 Plan), the site is located within the 60 DNL contour for the Minneapolis — Saint Paul International Airport (MSP). Figure 1 shows the project site location on the MSP noise contour map. 4r, 1, s - , 1Inn r G .... ....... „ , s .dim. , 4 " WI , i T. aA u'ATui .v.:, his ii re„, ... ,o.' %.• n». fxYf ` Olil 5.... ° l F 7S CAL y� r I J ' M • • •.. .... 70 DNL . a te , r 66 DNI_.- awmn .„,,„_, ;7,,,,' f' - • ' i ,,,t, 1110- ,-, 0 — ,..4 i • : 60DNL Project Site ln 11111 _. parr e a_—_L_�_.._ Uldlik — • ,.�,• Minneapolis - St Paul International Airport (MSP) 3 6 Mites I I I Figure 1 —MSP noise contours map showing project site location. 3. The City of Eagan Code, "Sec. 11.64 — ANZ — Aircraft Noise Zone Overlay District", has requirements for land uses affected by aircraft noise. "Subd. 6. Establishment of aircraft noise zones", states that land in a DNL 64-60 zone is an aircraft noise zone 4. Mr. Forsberg July 14, 2017 RSP Architects Page 3 4. In Table 1 of the Eagan code section, school land use categories in aircraft noise zone 4 have a "Conditional" land use compatibility. The Code defines conditional use as, "A use that is not permitted, unless it meets the structural performance standards as set forth in Table L-4, and the factors set forth in Table L-5 of the Metropolitan Council 2030 Transportation Plan, Appendix L — Land Use Compatibility Guidelines for Aircraft Noise." While the code references the 2030 Plan, the 2040 Plan is actually the correct reference. 5. According to the 2040 Plan, the project development type is an "Infill Development", which is defined as the following: pertains to an undeveloped parcel or parcels of land proposed for development, similar to or less noise-sensitive than the developed parcels surrounding it. 6. Table L-3 of the 2040 Plan provides land use compatibility guidelines for aircraft noise. According to the table, educational land use categories for infill development projects within a noise exposure zone of 64-60 DNL are considered a "Provisional" compatibility. 7. The 2040 Plan defines a provisional compatible land use as, "uses that should be discouraged if at all feasible; if allowed, must meet certain structural performance standards to be acceptable according to MS473.192 (Metropolitan Area Aircraft Noise Attenuation Act). Structures built after December 1983 shall be acoustically constructed so as to achieve the interior sound levels described in Table L-4. Each local governmental unit having land within the airport noise zones is responsible for implementing and enforcing the structure performance standards in its jurisdiction." 8. Table L-4 of the 2040 Plan states that aircraft sound level inside educational structures should not exceed 45 dBA. 9. Table 2 in the Eagan Code section 11.64 states that school buildings in aircraft noise zone 4 need to provide at least 19 dBA of noise reduction for compatibility. 10.Table 5 of the Eagan code section states that to achieve a noise level reduction of 20 dBA, the following STC ratings for building elements is required (the Table 5 footnote says the rating is actually 2 STC points less than the table values): a. Roof/Ceiling STC 38 b. Walls STC 38 c. Windows STC 28 d. Doors STC 18 These requirements match the ordinance recommendations in Appendix C of the Metropolitan Council Builders Guide. Mr. Forsberg July 14, 2017 RSP Architects Page 4 11.Along with the Table 5 STC requirements listed above, the City of Eagan Code Sec. 11.64.8.6.1.a. also requires the plans and specifications demonstrate compliance with the following to assure the elimination of sound leaks: a. All mechanical ventilation systems shall be installed that will provide the minimum air circulation and fresh air supply requirements as provided in the State and International Building Code for the proposed occupancy without the need to open any exterior doors or windows. b. The perimeter of all exterior windows and door frames shall be sealed airtight to the exterior wall construction. c. Fireplaces shall be equipped with well fitted chimney closing devices. d. All ventilation ducts, except range hoods, connection interior space to outdoors shall be provided with a bend such that no direct line of sight exists from the exterior to the interior through the vent duct. e. Doors and windows shall be constructed so that they are close fitting. Weather stripping seals shall be incorporated to eliminate all edge gaps. f. All penetrations through exterior walls by pipes, ducts, conduits, and the like shall be caulked airtight to the exterior construction. Building Element STC Review The MAC Skills Development Center building elements must meet the STC requirements listed in item 10 above. The following is a review of the STC ratings for each element: 1. The roof must have a minimum rating of STC 38. The building has two different roof types: a. A built up roof construction consisting of metal deck, cover board, vapor retarder, rigid insulation, EPDM membrane and minimum 9 psf ballast, as shown in Figure 2. Level 2 spaces below have either an ACT ceiling, gypsum board ceiling, or are open to the structure. Without a ceiling, the roof assembly has a rating of STC 46',which meets the STC 38 requirement. The ACT and gypsum board ceilings will only increase the roof assembly STC ratings further. STC laboratory test number TLF-99-015a by National Research Council Canada.

Mr. Forsberg July 14, 2017 RSP Architects Page 6 2. Exterior walls must have a minimum rating of STC 38. The exterior wall is a Fabcon precast concrete panel consisting of a 8 inch hollow-core concrete panel, 2-1/2 inch insulation, and 1-Y/2 inch finished concrete for the inner layer. By itself, 8 inch thick hollow-core concrete has a rating of STC 504,which meets the STC 38 requirement. 3. Windows must have a minimum rating of STC 28. The project has curtain wall (CMI 6600) and casement window (CMI 200T) systems from CMI Architectural that have ratings of STC 305 and STC 316, respectively, which meet the STC 28 requirement. 4. Doors must have a minimum rating of STC 18. Exterior door types include full glass aluminum double and single doors, and hollow metal double and roof hatch doors. All exterior doors will be tight fitting and have weather stripping seals to improve thermal energy conservation and sound isolation. All doors should have a rating of around STC 287, which meets the design goal. Sound Leak Prevention As listed in item 11 of the regulations discussion above, the Eagan Code requires the plans and specifications demonstrate compliance to assure the elimination of sound leaks. The following are our comments related to sound leaks through mechanical and other paths: 1. The building's HVAC system is designed to provide the minimum air circulation and fresh air supply requirements as provided in the State and International Building Code for the proposed occupancy without the need to open any exterior doors or windows. 2. The perimeter of all exterior windows and door frames will be caulked to create an airtight seal to the exterior wall construction. 3. The building does not have any fireplaces or chimneys, so this noise transmission path is not an issue. 4. All ventilation duct connecting interior space to the outdoors will have at least one bend, which prevents direct sound transmission from the exterior to the interior. All duct in the building is directly connected to equipment and there are no louvers open to the exterior of the building. 5. Doors and windows will be constructed so that they are close fitting, sealed, and caulked at the frame perimeter. Doors and operable windows will have weather stripping seals to eliminate all edge gaps. 4 STC laboratory test result listed in the Precast/Prestressed Concrete Institute Design Handbook. 5 In our opinion,STC laboratory test number RAL-TL10-380,by Architectural Testing for EFCO,is representative of a curtain wall type window system with 1/4"glass-1/2"airspace-'/4"glass. 6 In our opinion,STC laboratory test number RAL-TL10-380,by RAL for EFCO Corporation,is representative of a casement type window with 1/4"glass-1/2"airspace-1/4"glass. STC laboratory test number by the National Research Council Canada. Listed in Noise Control in Buildings by Cyril M. Harris, 1994. Mr. Forsberg July 14, 2017 RSP Architects Page 7 6. All penetrations through exterior walls by pipe, duct, conduit, and similar will be caulked to create an airtight seal to the building interior. Conclusions The City of Eagan and Metropolitan Council require new construction located within noise exposure zones to meet certain STC requirements for outdoor to indoor noise reduction. As designed, the new MAC Skills Development Center building meets these requirements. No modifications to the current design are required. We appreciate the opportunity to work with RSP on this project and remain available to assist in the resolution of these and any other matters. Please let us know if you have any questions or need more information. Sincerely, Andrew A.J. Schmitt Anthony J. Baxter, P.E. Consulting Engineer Principal ESI Engineering, Inc. ESI Engineering, Inc.
