May 4, 2017 ARCWEST Architects Attn: Robin Adams 2406 West 32cd Avenue, Suite A Denver, Colorado 80211 Re: Subsurface Investigation and Geotechnical Engineering Recommendations Proposed Additions to Existing Single -Family Residence, 3990 Brentwood Street Wheat Ridge, Colorado Job No. 17-142 Mr. Adams, As requested, KC Hamilton Engineering, Inc. (Hamilton) has prepared geotechnical engineering recommendations for the planned additions to the existing residential structure at the referenced site. REPORT SUMMARY AND SPECIAL CONDITIONS The site is underlain by a thin layer of topsoil and sod and by clayey sands and sandy clays to a depth of 30 feet, the maximum depth explored. Ground water was encountered in the boring at depth during drilling and at a depth of about 23 feet when check 8 days after drilling as discussed herein. The swell -consolidation testing indicated the potential for foundation and slab -on -grade heave of less than an inch. The foundation of the existing house is assumed to be conventional spread footings. This should be confirmed during construction. The foundation of the existing and new structure should be similar so the entire structure will generally behave in similar ways. Conventional spread footings can be considered for the planned additions, provided you a designers accept the risk of some potential foundation and/or slab -on -grade movell discussed herein. Wheat Ridge SCOPE OF WORK The scope included drilling two exploratory borings, obtaining soils and/or bedrock sample as intervals in the bore holes, and subjecting the samples to various tests as outlined herein to determine the sample engineering properties. The scope of work does not include an environmental assessment with respect to assessing potentially chemically impacted soils PO Box 300626 Denver Colorado 80203 Phone: 720-261-9358 KC Hamilton Engineering, Inc. Geotechnical Engineering Report 3990 Brentwood Street, Wheat Ridge Job No.: 17-142, May 4, 2017 Page 2 and/or ground water, nor did it include any geologic or mining hazards evaluation for the site or site vicinity. These types of work should be performed by others, if required. Limitations Inherent to the Scope of Work and Reporting; The recommendations presented herein are based on the subsurface conditions observed in the boring(s) and the testing results. Additional subsurface exploration may result in recommendations that may differ in some degree than those presented herein. There is no guarantee or warranty to the uniformity of subsurface materials and conditions at the subject site nor should these be implied by the reader of this report. SITE CONDITIONS The site consists of an existing single-family residence. The site is vegetated with sod, landscape plants and scattered to grouped trees. Site drainage appears to be fair to poor, and the site appears to have little slope down to the west. A site plan is presented on Figure 1.0. Existing Structure: It is understood that the existing structure is in relatively good condition with no significant problems due to settlement or heaving soils such as cracked floors, cracked masonry, and racking of door and window openings. Hamilton is unaware of any moisture issues with the existing structure. If there have been issues in the past with respect to the assumptions presented herein, Hamilton should be notified to re-evaluate the recommendations provided in this report, if necessary. PROPOSED CONSTRUCTION Additions to the front and rear of the existing residence are proposed. No basements are planned. Reinforced concrete foundations supporting a wood -framed structure are planned. Structural loading will be relatively light consistent with residential construction. Excavations will be in the range of 3 to 6 feet deep. Site grading will be minimal with cut and/or fill slopes less than 4 feet in height. If the proposed construction varies from that described above or herein, Hamilton should be notified to re-evaluate the recommendations provided in this report, if necessary. , CRY of SUBSURFACE INVESTIGATION (ab&g heat Ridge The subsurface investigation was performed by drilling one boring (B-1) on the sitthe �IVISO� approximate location shown on Figure 1.0. The boring was drilled on 04-25-2017 using mounted CME 45 drilling rig. Samples were obtained by driving a "modified California" sampler into the subsurface materials at selected depths during drilling as noted on the boring log(s). The modified California sampler is a steel barrel sampler with a 2 -inch inside diameter (ID) and a 2.5 inch outside diameter (OD) that is fitted with 4 -inch long brass liners. The liners facilitate retrieval and transport of relatively undisturbed finer -grained samples of the subsurface materials. The degree of sample PO Box 300626 Denver Colorado 80203 Phone: 720-261-9358 KC Hamilton Engineering, Inc. Geotechnical Engineering Report 3990 Brentwood Street, Wheat Ridge Job No.: 17-142, May 4, 2017 Page 3 disturbance is dependent on the soil and bedrock type and the in-situ moisture content and density conditions of the materials sampled. Hard and dry samples tend to be disturbed regardless of the sampling technique. The sampler was driven into the subsurface materials using a 140 -pound hammer falling through a height of 30 inches. The number of blows (blow count) required to drive the samplers 12 inches is recorded and provides an indication of the relative density of granular materials or and relative consistency of cohesive, fine grained soils. SUBSURFACE CONDITIONS The site is underlain by a thin layer of topsoil and sod and by clayey sands and sandy clays to a depth of 30 feet, the maximum depth explored. A log of the boring is presented on Figure 2.0. Selected soil and bedrock samples were tested for natural moisture content and dry density, percentage passing the No. 200 sieve, and swell -consolidation potential. The lab results are presented next to the log on Figure 2.0, and on Figures 3.0 and 3.1. Ground Water: Ground water was noticed seeping into the boring at depth during drilling, and at a depth of about 23 feet when checked 8 days after drilling. The depth to ground water may vary seasonally with higher groundwater levels in the spring as opposed to drier months, and may vary by several feet from the measurements presented in this report. Ground water can also flow through cracks and fissures in soils and bedrock, and may also perch' on the surface of bedrock, in pervious layers of bedrock, or on layers of impervious or low -permeable soil or bedrock. Construction may disrupt the natural or developed surface and/or subsurface flows of water thus allowing 'perched' conditions to develop. The clayey soils may allow for seasonal perched water to develop; therefore, good surface drainage should be incorporated into the site planning. Refer to the Subsurface Drainage section of this report for crawl space, void space, and basement slab protection recommendations.

Geotechnical Engineering Report 3990 Brentwood Street, Wheat Ridge Job No.: 17-142, May 4, 2017 Page 5 SITE PREPARATION, EARTHWORK, AND EXCAVATIONS The following should be incorporated into the site grading plans and excavation planning: 1. Areas to be graded should be stripped of surface vegetation, topsoil, wood, root zones, debris, existing manmade fills, and other deleterious (degradable) material. Stripped and degradable materials should be wasted off site in accordance with applicable regulations. 2. Clean soils free from debris and organic materials may be usable as fill once these materials are better exposed and observed by the engineer, and as discussed below. 3. All existing foundation structures, uncontrolled fills, or other manmade objects within the proposed footprints of new structures and flatwork should be removed down and laterally to natural materials, and replaced with properly compacted fills as recommended herein. 4. Topsoil, frozen materials, ice, snow, cobbles and boulders larger than 3 inches, debris and other deleterious material should be excluded from materials being considered for reuse on site. S. Hamilton should be contacted to review proposed backfill materials and to observe all excavation bottoms prior to backfill. Foundation and Floor Slab Subgrade Preparation: Soft or disturbed soils observed in the foundation and floor slab excavations should be compacted in place or removed and replaced with structural fill as directed by the Engineer. Any fill placed below foundations should consist of granular, non -expansive soil compacted to at least 95% of the standard Proctor maximum dry density (ASTM D 698) and as outlined in the Site Preparation section of this report. Reuse of On -Site Materials: The clayey sands are not suitable for reused as structure backfill below foundations or slabs -on -grade. These soils can be reused as wall backfill in landscape areas. Structural Fill Material: Imported structure backfill material, if necessary, should be non - expansive at its recommended placement moisture content and density, classify as a coarse- grained material (sand or gravel) by the Unified Soil Classification (USC) system, and have a liquid limit (LL) less than 40 and a plasticity index (PI) of 10 or less. Suitable imported structural materials would be: CDOT Class 5 or 6 aggregate road base, materials meeting the CDOT Class 1 Structure Backfill, or a manufactured 'crusher fines' materials.

Geotechnical Engineering Report 3990 Brentwood Street, Wheat Ridge Job No.: 17-142, May 4, 2017 Page 6 Structure Backfill Placement: For fill thicknesses of less than 8 feet, the structural backfill should be placed in maximum loose lifts of 8 inches; moisture conditioned as necessary, and compacted to 95 percent or more of the standard Proctor Maximum Dry Density (MDD): ASTM D 698. Fill which classifies as silt, sand or gravel by the USC system should be moisture conditioned to within 2 percentage points of Optimum Moisture Content (OMC). Fills which classifies as clay by the USC system should be moisture conditioned to within OMC to 3 percentage points above OMC. General fills in non-structural areas and with thicknesses of less than 8 feet should be compacted to at least 90 percent of the MDD, and to the moisture contents outlined above. If fill thicknesses will exceed 8 feet, greater degrees of compaction may be recommended. Recycled Concrete: Recycled concrete products are less expensive than crushed stone or mountain rock, and readily available. However, recycled concrete will leach calcite and other minerals that can potentially clog and/or reduce the effectiveness of an underdrain system. Backfill Testing and Monitoring: The areas and excavations receiving structural fills should be observed by the Engineer prior to fill placement. In addition, testing of the backfill materials during placement should occur to insure the recommended moisture contents and degrees of compaction have been achieved. Typical testing frequencies should be observed with compaction testing at depth, mid -depth and near the surface of backfill zones. General Site Excavations: The upper sandy soils classifies as Type C soils per the OSHA Excavation Guide. The excavation slope in these materials should be laid back per as per the OSHA Excavation Guide for Type C soils 1.5:1 (H:V) or 34 degrees. OSHA excavation guidelines are for excavations not exceeding a depth of 20 feet. Excavation Safety; Site excavations should be performed under the supervision of the contractors 'Competent Person' per the OSHA Excavation Guide. The slopes may require to be further laid back if seepage is observed in the excavations. The contractor should manage construction traffic and the placement of excavation spoils to maintain excavation slope stability. All on-site drainage and adjacent drainage should be managed and be diverted away from the excavation cuts. The on-site soils are easily eroded. FOUNDATION RECOMMENDATIONS Conventional spread footings can be considered for the planned structure provided you, the owner(s), and the designers accept the risk of some potential foundation and/or slab-rstable movement. The swell -consolidation testing indicated the potential for foundation heav than an inch. of Conventional Spread Footing Foundation Design: Spread footings bearing o natural soils or improved subgrades should be designed based on a maximum allowabhe `9-61V Divison bearing pressure (Qa) of 1,500 psf with at least 12 inches of embedment, and a_ minimum dead load of 500 psf. If the minimum dead load cannot be achieved, the designer PO Box 300626 Denver Colorado 80203 Phone: 720-261-9358 KC Hamilton Engineering, Inc. Geotechnical Engineering Report 3990 Brentwood Street, Wheat Ridge Job No.: 17-142, May 4, 2017 Page 7 should consider using 'interrupted footings' or a pad and beam foundation system with 4 -inch void spaces. Additional Foundation Design Criteria: The following should also be considered for the design and construction of a spread footing foundation system. 1. The total and differential settlements across the building footprint(s) are estimated to be approximately 1 inch or less based on typical geotechnical engineering design methods. If lesser degrees of settlement are preferred, Hamilton should be contacted. 2. Spread footings should have a minimum width of 16 inches for continuous footings and 24 inches for isolated pads. 3. Footings placed beneath unheated areas should have at least 36 inches of covering soils to protect from frost. This depth should be verified with the local building department. 4. Lateral resistance to of the spread footings is based on both friction between the footing and its subsoils and passive earth pressures of the soils on the side of the footing. A coefficient of friction of 0.35, and a passive pressure based on an equivalent fluid weight of 200 pcf are recommended for the onsite sandy soils. These values should be considered working values with a safety factor of 1.5 included for the passive earth pressure value. 5. Continuous footing should be reinforced to and bottom to span an unsupported length of 10 feet. 6. A representative of the Engineer should observe to foundation excavation prior to foundation construction and/or fill placement. 7. The foundation excavation should be protected from runoff, and multiple wetting and drying cycles. Runoff into the foundation excavations should be avoided. Foundation excavations should not be left open for extended periods of time. Foundation subgrades can be degraded and weaken after repeated wetting and drying cycles. Foundation Subgrade Preparation; Soft or disturbed soils observed in the foundation excavations should be compacted in place or removed and replaced with structural fill as directed by the Engineer. Any fill placed below foundations should consist of granular, non - expansive soil compacted to at least 95% of the standard Proctor maximum dry density (ASTM D 698) and as outlined in the Site Preparation section of this report. INTERIOR FLOOR SLABS The onsite soils are suitable to support slab -on -ground construction with a low risk of slab heave due to potentially expansive soils. Heave estimates are estimated to be less than an inch based on the testing presented herein. Settlements, if these occur, are also anticipated to be less than an inch. Structural floors over a crawlspace (or minimum 6 -inch void space) are recommended. or ah0YOf finished living space if the risk of movement for slab on grade construction is not acre , f. ftt Ridge Home warranty policy companies involved with the project should also be consQ;lted, as applicable, for their potential floor slab heave limits. `��uiidjnq Divin, ,.

Geotechnical Engineering Report 3990 Brentwood Street, Wheat Ridge Job No.: 17-142, May 4, 2017 Page 8 Slab -On -Grade Design: If selected, the following should be incorporated into the slab -on - grade design: 1. To reduce the effects of differential movement, floor slabs on grade should be separated from all bearing walls and columns with expansion joints that allow for unrestrained vertical movement. 2. Partition walls should not be designed or constructed to bear on slabs supported on grade. 3. A 1.5 -inch void should be established below or above partitions during construction and monitored and maintained by the owner after construction. The void space can be covered with a molding strip that is not attached to the partition. 4. Joint spacing should be determined on floor thickness, nominal aggregate size, slump, and be consistent with the recognized guidelines such as the Portland Cement Association and the American Concrete Institute (ACI). Slab Subgrade Preparation: Some areas of soft soils may be encountered in the floor slab areas. Soft or disturbed soils observed in the foundation excavation should be compacted on grade or removed and replaced with structural fill. Any fill placed below foundations should consist of granular, non -expansive soil compacted to at least 95% of the standard Proctor maximum dry density (ASTM D 698) as outlined in the Site Preparation section of this report. Plastic Moisture Barrier and Sub -Floor Gravel Layer: Based on the subsurface information obtained in the borings, a sub -floor filter fabric blanket, sub -floor gravel layer, and plastic moisture barrier appear to optional for this project. If installed, you and the designers should consider a Stego° Wrap or other similar products as the moisture vapor barrier. Interior Plumbing: All plumbing lines should be testing for leaks. Where plumbing lines enter through the slab, positive breaks should be provided. Connections to mechanical equipment should be flexible. Floor Coverings: Cracks and movement of the slabs supported on grade can be transmitted through rigid floor coverings, such as tile or even decorative concrete. Performance expectations should be taken into consideration in the selection of floor slab coverings. Slab Cracking and Materials Testing: There are various causes for concrete slabs to crack including but not limited to: poor subgrade support, expansive soils, frost heave, insufficient quantity and spacing of control joints, in adequate reinforcement, excessive water being added to the concrete during placement, and improper curing methods. The designers should incorporate into the project specifications typical concrete construction and material requirements to reduce the potential for slab cracking. Applicable ACI guidelines should be followed for design, construction and materials handling. Testing of the concrete for slump, entrained air, and temperature, and collecting sales fo strength testing are suggested. city Of Wheat Ridge Widing PO Box 300626 Denver Colorado 80203 -Phone: 720-261-9358 KC Hamilton Engineering, Inc. Geotechnical Engineering Report 3990 Brentwood Street, Wheat Ridge Job No.: 17-142, May 4, 2017 Page 9 RADON, MOLD, AND CRAWLSPACES Radon: Radon may be a potential concern in Colorado. If a crawl space is constructed it should be well ventilated. If a gravel layer is placed beneath the floor slab it can be incorporated into a radon abatement system if this becomes necessary in the future. The local building department should be contacted regarding any radon problems with other residences in the vicinity of the existing residence. Radon Prevention methods should conform to EPA Radon Mitigation Standards: EPA 402-R-93-078, October 1993 and revised April 1994. Mold: Mold can develop in crawl spaces that become damp under certain conditions. If a crawlspace is constructed, it should be well ventilated. A vapor barrier should be placed on exposed soil to help control indoor moisture levels. A professional hygienist should be contacted to address any potential mold concerns and mitigation methods. Refer to the EPA Home Buyer's and Seller's Guide to Mold for additional information: EPA 402-K-02-003, dated September 2010, for more information. Crawlspaces: A health and safety professional with experience in the design of crawlspaces can be consulted to provide recommendations to reduce moisture infiltration into crawlspaces. Such recommendations may include lining the crawlspace with polyethylene plastic that is sealed and mechanically attached to the foundation. Plastic should not be attached to the foundation within 6 inches of untreated wood members of the framing or flooring. Also, plastic should not be attached to metal framing members such as column posts, but can be attached to concrete foundations supporting column posts. Sealing products such as StegoCrawlT" Wrap or other similar products should be considered for crawl spaces if the owner would prefer to protect the crawlspace. FOUNDATION WALLS Foundation walls which are laterally supported and expected to undergo a minimal to moderate amount of movement should be designed with a lateral 'at -rest' earth pressure based on an equivalent fluid weight of 55 pcf if the onsite soils are used as backfill, excluding topsoil. The earth pressure can be reduced to 45 pcf for 'active' conditions where significant wall deflection can occur and as allowed by local building code, and for site retaining walls. Potentially expansive materials should not be used as wall backfill. These pressures assume drained conditions behind the foundation walls. The buildup of water behind a foundation wall will increase the lateral pressures on the wall. Lateral resistance to of the spread footings supporting foundation walls is based on both friction between the footing and the subsoils, and passive earth pressures of the soils or backfill on the side of the footings. A coefficient of friction of 0.35, and a passive pressure based on an equivalent fluid weight of 200 pcf are recommended for the onsite soils. These valu9s shou4cl be considered working values with a safety factor for the passive earth pressurg°"valuer,; ;ill foundation walls should be designed for appropriate hydrostatic and surcharge pressures such as: adjacent buildings, traffic, construction materials and equipment. i ',```Heat Ridge PO Box 300626 Denver Colorado 80203 Phone: 720-261-9358 KC Hamilton Engineering, Inc. Geotechnical Engineering Report 3990 Brentwood Street, Wheat Ridge Job No.: 17-142, May 4, 2017 Page 10 Foundation Wall Backfill Placement. In landscape areas, foundation wall backfill should be compacted to at least 90% percent of the standard proctor maximum dry density (ASTM D 698) near the optimum moisture content (OMC). In areas of external and interior flatwork (i.e. sidewalks, patio areas, driveways, garage slabs), foundation wall backfill should be compacted to at least 95% percent of the standard proctor maximum dry density (ASTM D 698) as outlined in the Site Preparation section of this report. SUBSURFACE DRAINAGE It is recommended that any below -grade, finished living spaces, mechanical or storage spaces be protected from surface water infiltration with a perimeter drain system. A detail of typical drainage system is presented in Attachment B. Any construction warranty companies involved applicable, for their subsurface drain policies. requirements other than that presented herein. SURFACE DRAINAGE with the project should also be consulted, as These polices may require additional drainage The following drainage recommendations and precautions should be observed for the site planning phase of the project, and maintained at all times during and after construction: 1. Excessive wetting of the foundation excavations, sub -floor soils, pavements subgrades, and exterior flatwork subgrades, should be avoided during and after construction. Excessive wetting of open foundation excavations may degrade and soften subgrade materials and may require additional excavation and/or subgrade stabilization. 2. Exterior foundation wall backfill should be placed and compacted, and graded as recommended herein. 3. The ground surface around the structure should be sloped away from the building. A minimum slope of 12 inches in the first 10 feet (10%) in landscaped areas and 2.5 inches in 10 feet (2%) in paved ADA areas and 3% in other paved areas. 4. Lesser slopes in the landscaped areas can be created provided runoff is adequately diverted off site with swales, catch basins and pipes, 'French' drains, etc. A qualified designer should be consulted to develop an adequate drainage plan for the site. 5.

Excessive runoff from adjacent properties onto the site may adversely impact site excavations and shoring, and potentially shallow unprotected crawl spaces. Establishing good site drainage is the responsibility of the developer, site designers and general contractor, and final grading plans should reflect the recommendations presented herein. Maintaining good site drainage after construction is the responsibility of the owner. Drainage Limitations: The recommendations, presented herein and associated with site drainage, are not based on providing protecting against any one major storm event (e.g. the 100 -year storm) or localized street flooding, but what are typically recommended by geotechnical engineers in area. Once the site design nears completion, and particularly if site drainage appears to be problematic with respect to the lack of adequate site slopes, or lack of pathways to provide routes to public storm water collection systems, or the potential to adversely impact adjacent properties, a qualified site designer should be consulted to develop a site specific drainage plan. DRIVEWAY AND EXTERIOR FLATWORK RECOMMENDATIONS Areas receiving new flatwork should be prepared as outlined in the Site Preparation section of this report. The subgrade soils should be scarified and compacted to at least 95% of the standard Proctor maximum dry density near the optimum moisture content in areas of driveway pavement or approach apron for a garage, if constructed. Proof -rolling of these areas is recommended. Soft and deflecting areas should be removed and replaced with properly compacted fill. LIMITATIONS AND EXCLUSIONS This study has been conducted in accordance with generally accepted geotechnical engineering practices in this area and for use by the client for design purposes. An additional discussion of the limitations of geotechnical engineering practices is presented in Attachment A. An environmental site assessment (ESA Phase I or II) was not a part of the proposed scope of work for this reporting, and should be performed by others if required by you. Any obvious chemical or petroleum odors or staining are noted in the Subsurface Conditions section of this report. This report should also not be considered as an indication of the absence of or as an evaluation of any potential environmental, geologic or mining hazards for the subject site. The conclusions and recommendations presented in this report are based on the data obtained from the exploratory boring(s) drilled at the approximate location presented on Figure 1.0, and-°� the proposed construction. If during construction, fill, soil or groundwater conditions appear to ©f be different than that presented in this report, Hamilton should be contacted to reevaluate the recommendations presented herein, if necessary.

ATTACHMENT A Important Aspects of Geotechnical Engineering, And Risks Associated with Building on Expansive Soil -Bedrock Sites Subsurface Data: The data collected by KC Hamilton Engineering, Inc. (Hamilton) and presented herein was used to provide geotechnical information and recommendations for the planned structure(s) and/or construction. These recommendations include the potential effects of the subsurface conditions on the proposed structures and the recommended foundation type for the proposed structure(s). Additional information from additional borings will provide for a better understanding of the subsurface conditions at the site and the potential impact to the planned structures. The stratification lines shown on the boring log(s) are approximate and actual transitions between materials may be more gradual or more definitive than indicated on the log(s). Drilling equipment is not sensitive to gradual changes in subsurface conditions. It should be understood that natural soil and bedrock conditions are variable, and the actual subsurface conditions encountered during construction may differ to some degree from the subsurface conditions presented herein. The material characteristics and engineering properties of soil and bedrock may also vary between samples and between borings. The actual material characteristics and engineering properties of the soil or bedrock may differ from location to location and from the depths the samples are obtained, and differ from the information presented in this reporting. Quantitative (and/or absolute) conclusions regarding the geotechnical performance of a structure are not possible due to the potential variability of subsurface conditions and the small number of borings typically drilled for this type of study. The anticipated performance of a structure, as discussed in the body of the report, is an estimation only, and the actual performance may vary. Engineering judgment and experience are used to evaluate the most likely geotechnical performance of the structure and provide geotechnical recommendations for the structure. The site owner, and project designers and contractors should not assume that guaranties or warranties are implied or expressed with respect to the future performance of the structure. The risks associated with building on the subject site of this report are the site owner and theirs alone. Report Expiration: The report should not be used more than three years after issuance unless reviewed, and revised if necessary, by HAMILTON. Risk Description: The site owner, Hamilton's direct client, and the project designers must understand that there are uncertainties associated with geotechnical engineering and they must determine the level of risk they are willing to accept for the proposed construction. The level of risk can be reduced, but not eliminated by more extensive exploration and sampling of the site and additional laboratory testing, which would be more costly and time consuming. To reduce the level of uncertainty, the report should only be used by the owner, designers, and contractors for the referenced site and project, and the proposed construction as described in the report. Any changes in the planned construction after this report has been issued should be brought to the attention of Hamilton and this report revised, if necessary.

Appendix A - Geotechnical Engineering Last Revised 07-25-2014 Page 2 HAMILTON should be consulted to review any changes to the proposed construction such as the nature, size, configuration, orientation, location or weight (loading) of proposed improvements. Additionally, the practice of geotechnical engineering is continually developing knowledge and experience, and it must be understood that recommendations are based on the state of the practice at the time the report was prepared. The geotechnical engineering practice in the Colorado Front Range area uses a relative classification to evaluate the expansive potential of soils and bedrock. The expansive potential is categorized as low, medium, high or very high based on the swell potential. The following table presents the relative classifications. Summary of Risk Categories Slab Performance Risk Category Representative Percent Swell (500 sf Surcharge) Representative Percent Swell (1000 sf Surcharge) Low 0 to< 3 0 to< 2 Moderate 3 to < 5 2 to < 4 High 5to<8 4to<6 Very High 8 or greater 6 or greater Source: coiorado Association of ueotecnnical Lnglneers, "Guideline for Slab Performance Risk Evaluation and Residential Basement Floor System Recommendations (Denver Metropolitan Area), December 1996 Potential Structure Damage: The slab performance generally associated with the slab performance risk categories are as follows: Heave Risk Category Potential Slab Performance Issues Low: slab cracking, differential movement and heave Moderate: slab cracking, differential movement and heave, partial framing void and furnace plenum closure, some structural element separation High to Very High: large slab cracking, differential movement and heave, closed framing void and furnace plenum, structural element separation Note; More or less damage can occur in any risk category due to the variable nature of soil and bedrock. Other Factors Considered for the Reoorting: It is important to note that measured swell or expansion in the samples obtained for this project, is not the only criteria used in developing foundation and floor recommendations. Other factors considered in the development of foundation and floor recommendations are: a. Soil and bedrock variability, b. Stratigraphy, c. Groundwater depth during field activities and potential groundwater depth after construction, d. Surface water features and site drainage, e.

Appendix A - Geotechnical Engineering Last Revised 07-25-2014 Page 3 f. Construction details and proposed use, and g. Local experience. Risk Comparison between Expansive Soil and Expansive Bedrock. It should be noted that expansive bedrock, is typically and potentially more problematic with respect to heave than expansive soils during the life of the structure. The expansive bedrocks are typically the parent material' of the expansive over -lying soils, are less weathered, and possess the capacity to induce higher swell pressures on slabs and foundations than soil. Depth of Wetting and Heave Estimates: The assumed depth of wetting and swell -consolidation potential are a part of the heave estimates presented in this report. For this report, the depth of wetting is assumed to be about 20 feet below the existing grades, or down to the depth of ground water, whichever is greater. This depth of wetting is typical for engineering practices along the Colorado Front Range. However, if there are significant variations in in-situ moisture contents of subsurface materials below the water table from what would be expected, the depth for wetting may be greater than the depth to the water table. In some areas, recent development may have created shallower water tables than the originally conditions prior to development. For example, the assumed depth of wetting is sometimes reduced if ground water is encountered within 20 feet of the surface and depending on whether or not the materials below the water level appear to have been wetted (i.e. elevated moisture contents.) Soils are generally wet below the surface of the water table. Bedrock may not be wetted below the water level depending on the type of the bedrock and the degree of jointing and/or fracturing. Sandstones may transmit water and be more easily wetted, but claystone may not transmit water very well and may be only partially wetted at or near fractures and joints. The assumed depth of wetting by engineers has increased over the years along the Denver Front Range as more structures have been built, and more research and observations have been made. Shrink - Swell.- Expansive soils near the ground surface will be more subject to cyclical 'wetting' (moisture increases) due to seasonal precipitation, irrigation, site drainage, and also seasonal drying during the warmer and/or low -precipitation periods of the year. This may result in shrink -swell cycles for the materials. The cyclic shrink and swell actions of an underlying soil may induce some degree foundation and slab movement over time. Long -Term Wetting: The 'wetting' of subsoils below a structure can also occur from the gradual movement of moisture by the 'soil suction' properties of the underlying soils during the life of the structure. For example, the moisture content of dry clay below a structure may increase over time since the structure will essentially 'cap' the area and reduce or eliminate the natural evaporation of the moisture from the soil. Moisture is then slowly 'pulled' into the subsoils from the perimeter of a structure by the soil suction properties from subsoils. Some degree of movement is typically the result of this on expansive -soil sites. 'at Ridge Effects of Landscaping and Runoff: Landscaping of the site following construction and owner maintenance of it will greatly affect the performance of structures on sites with expansive soil or bedrock. Typically, moisture contents of subsurface soils and bedrock increase after construction due to surface irrigation and the cut off of evaporation that occurs when a slab or building is constructed. Poor PO Box 300626, Denver, Colorado 80203 Phone: 720-261-9358 KC Hamilton Engineering, Inc. Appendix A - Geotechnical Engineering Last Revised 07-25-2014 Page 4 owner maintenance, such as ground surfaces sloping towards foundations or slabs, and irrigated landscaping adjacent to buildings, will increase the potential for slab and foundation movement to occur by increasing the potential for moisture content changes in the subsurface soils. Conventional Foundations and Expansive Soil Sites: Depending on the degree of swell potential and the type of expansive materials at a site, conventional spread footings can sometimes be constructed provide the swell -consolidation testing indicates swell potentials of less than 2% and swell pressures of less than 3,000 pound per square foot (psf), and provided the owners and designers accept the potential for foundation and/or slab movement. The potential use of conventional foundations on the subject site is presented in the Foundations Recommendations section of this report. The potential for foundation movement can sometimes be reduced by increasing dead loading and depth of the foundations but will not eliminate the potential for movement. Slabs -On -Grade and Pavements: Slabs -on -grade, exterior flatwork, and pavements will be more susceptible to potential heave than foundations due to the low dead load these apply to the ground. These structures will exhibit more pronounced damage and movement than heavier loaded foundations. Structural Damage: Damage to structures with conventional foundations built on expansive soil sites may consist of minor cracking of masonry, drywall and plaster, stucco, etc., and the slight racking of window and door frames for sites with low -heave -potential soils. The damage may be relatively significant for sites with moderate- to very -high -heave -potential soils and bedrock. Deep foundations and structural flooring are typically selected to minimize the potential for heave and the associated damage to a structure. Acceptance of Risk: Any heave predictions discussed in the report are based on the swell - consolidation testing presented in the report. The actual heave potential may vary as discussed above. As mentioned, additional borings and swell -consolidation testing can refine any of the heave predictions presented herein. For expansive soil/bedrock sites, the selection of the foundation type for the proposed structure is essentially an acceptance of some level of risk by you and/or the owner, and designers. Deep foundations can be an expensive component to construct for any structure but will typically have the least amount of risk for movement, as well as structural floors when compared with slabs -on -grade. Conventional spread footing foundations are typically much less expensive to construct but may have a higher potential for heave depending on site soil and bedrock conditions, the low structural loading (as is the case for most residential construction), site drainage, and the long-term maintenance of the structure and site. The recommendations presented in the body of the report, are presented to reduce the risk of movement and damage from expansive soils and bedrock and should be considered very carefully, and weighted against the budget for the project, and what level of risk is acceptable to you and/or the' owner, and designers. Home warranty policies that will be issued by the developer and contractoridge should also be referenced for the levels of acceptable risk they will cover. wilding ❑ivison The property owner, and anyone they plan to sell the site to, must understand the risks associated wit construction in areas with expansive materials, and must assume the responsibility for maintenance of the structure and the site.
