So LocsIc September 20, 2021 Lawrence Walker 9712 Sierra Vista Road Longmont, Colorado 80501 Re: Geotechnical Subsurface Exploration Report Proposed Addition to Existing Residence Lot 1, Block 3, Casagrande Estates 9712 Sierra Vista Road Weld County (Longmont), Colorado Soilogic Project # 21-1287 Mr. Walker: Soilogic, Inc. (Soilogic) personnel have completed the geotechnical subsurface exploration you requested for the proposed addition to your existing residence located on Lot 1 of Block 3 in the Casagrande Estates residential development near Firestone, in unincorporated Weld County, Colorado. The results of our subsurface exploration and pertinent geotechnical engineering recommendations are included with this report. We understand the proposed addition will be a single -story wood -frame garage constructed as slab -on -grade with approximate dimensions of 36 feet by 42 feet and will be connected to the existing residence via a breezeway. The addition will be constructed on the south side of the residence adjacent to a basement area of the existing residence. Foundation loads for the addition are expected to be relatively light, with continuous wall loads less than 3 kips per lineal foot and individual column loads (if any) less than 50 kips. Small grade changes are anticipated to develop finish site grades in the area of the proposed addition. The purpose of our exploration was to describe the subsurface conditions encountered in the completed site boring and develop the test data necessary to provide recommendations concerning design and construction of the addition foundations and support of floor slabs. The conclusions and recommendations outlined in this report are based on results of the completed field and laboratory testing and our experience with subsurface conditions in this area. Soilogic, Inc. 3522 Draft Horse Court • Loveland, CO 80538 • (970) 535-6144 Geotechnical Subsurface Exploration Report Proposed Addition to Existing Residence (Lot 1, Block 3, Casagrande Estates) 9712 Sierra Vista Road, Longmont, Colorado Soilogic # 21-1287 2 SITE DESCRIPTION The proposed addition will be constructed on the south side of the existing residence situated on Lot 1 of Block 3 in the Casagrande Estates residential development, located at 9712 Sierra Vista Road near Firestone (but has a Longmont mailing address), in unincorporated Weld County, Colorado. We understand the existing residence is a single - story wood frame structure constructed over a full basement and we anticipate it is supported by a spread footing foundation system. At the time of our site exploration, the proposed construction area was being used as a horse pen and the ground surface was generally devoid of vegetation or contained a very sparse growth of native weed and grass vegetation and was relatively level. The maximum difference in ground surface elevation across the addition footprint was estimated to be on the order of two (2) feet or less. EXPLORATION AND TESTING PROCEDURES To develop subsurface information in the area of the proposed addition, one (1) soil boring was extended to a depth of approximately 15 feet below present site grade at the approximate center of the addition footprint. The boring location was established in the field by Soilogic personnel by referencing approximate addition corner stakes which had been placed by the client and by pacing and estimating angles and distances from these references. A diagram indicating the approximate boring location is included with this report. The boring location indicated on this diagram should be considered accurate only to the degree implied by the methods used by the client and Soilogic personnel to make the field measurements. A graphic log of the auger boring is also included. The test hole was advanced using 4 -inch diameter, continuous -flight auger powered by a truck -mounted CME-45 drill rig. Samples of the subsurface materials were obtained at regular intervals using California barrel sampling procedures in general accordance with ASTM specification D-1586. Penetration resistance measurements were obtained by driving the standard sampling barrel into the substrata using a 140 -pound hammer falling a distance of 30 inches. The number of blows required to advance the sampler a distance of 12 inches is recorded and helpful in estimating the consistency or relative density of the soils encountered. In the California barrel sampling procedure, lesser disturbed samples are obtained in removable brass liners. Samples of the subsurface materials obtained in the Geotechnical Subsurface Exploration Report Proposed Addition to Existing Residence (Lot 1, Block 3, Casagrande Estates) 9712 Sierra Vista Road, Longmont, Colorado Soilogic # 21-1287 3 field were sealed and returned to the laboratory for further evaluation, classification and testing. The samples collected were tested in the laboratory to measure natural moisture content and were visually and/or manually classified in accordance with the Unified Soil Classification System (USCS). The USCS group symbols are indicated on the attached boring log. An outline of the USCS classification system is included with this report. As part of the laboratory testing, a calibrated hand penetrometer (CHP) was used to estimate the unconfined compressive strength of essentially -cohesive specimens. The CHP also provides a more reliable estimate of soil consistency than tactual observation alone. Dry density, Atterberg limits, -200 wash and swell/consolidation tests were completed on selected samples to help establish specific soil characteristics. Atterberg limits tests are used to determine soil plasticity. The percent passing the #200 size sieve (-200 wash) test is used to determine the percentage of fine-grained materials (clay and silt) in a sample. Swell/consolidation tests are performed to evaluate soil volume change potential with variation in moisture content. The results of the completed laboratory tests are outlined on the attached boring log and swell/consolidation test summary. SUBSURFACE CONDITIONS The materials encountered in the completed site boring can be summarized as follows. Brown/rust silty sand was encountered at the surface at the boring location. The silty sand varied to clayey silt with increasing depth, varied from loose to medium dense in terms of relative density, exhibited no swell potential at current moisture and density conditions and extended to the bottom of boring at a depth of approximately 15 feet below present site grade. The stratigraphy indicated on the included boring log represents the approximate location of changes in soil types. Actual changes may be more gradual than those indicated. Groundwater was not encountered in the test boring to the depth explored (approximately 15 feet below ground surface) when checked immediately after completion of drilling. Groundwater levels will vary seasonally and over time based on weather conditions, site Geotechnical Subsurface Exploration Report Proposed Addition to Existing Residence (Lot 1, Block 3, Casagrande Estates) 9712 Sierra Vista Road, Longmont, Colorado Soilogic # 21-1287 4 development, irrigation practices and other hydrologic conditions. Perched and/or trapped groundwater conditions may also be encountered at times throughout the year. Perched water is commonly encountered in soils overlying less permeable soil layers and/or bedrock. Trapped water is commonly encountered within more permeable zones of layered soil and bedrock systems. The location and amount of perched and/or trapped water can also vary over time. ANALYSIS AND RECOMMENDATIONS General Careful observation of the exposed foundation bearing materials should be completed at the time of construction to ensure all footing foundations will be supported on materials with suitable strength and low volume change potential. If more extensive zones of very loose/disturbed clayey/silty sands or otherwise unsuitable soils are encountered at that time, some overexcavation/backfill or other approved stabilization procedures may be required. Care should be taken during excavation to avoid disturbing those soils providing support to the existing residence spread footing foundations (extending down at a 1:1 slope from the bottom edges of the foundations). As the breezeway addition foundation is expected to bear at comparatively shallow depth, disturbance of the adjacent basement foundation bearing soils would not be expected. Undocumented fill soils are expected to exist adjacent to the residence basement foundation wall in the breezeway addition area. Undocumented fill soils would not be considered suitable for support of any site improvements. Designing the breezeway addition foundation walls to span the existing backfill zone, extending footing foundations to bear on natural, undisturbed silty sand with low volume change potential at/near basement foundation bearing depth, or performing overexcavation/backfill procedures to redevelop controlled and compacted fill beneath new footing foundations in this area could be considered. Geotechnical Subsurface Exploration Report Proposed Addition to Existing Residence (Lot 1, Block 3, Casagrande Estates) 9712 Sierra Vista Road, Longmont, Colorado Soilogic # 21-1287 5 Site Development Within the proposed addition areas, any existing foundations, floor slabs and any other site improvements should be completely removed. Care will be needed to ensure all in -place fill/backfill materials associated with the existing residence are also completely removed at this time (unless the breezeway addition foundations are designed to span these zones). In addition, all tree root systems and dry and desiccated soils associated with the tree root systems should be completely removed from within the area of the proposed addition. The depth and extent of required removal can best be established at the time of excavation through openhole observation. If/where required, the excavated/removed materials should be replaced as controlled and compacted fill as outlined below. After stripping and completing all cuts and removal procedures and prior to placement of any fill/removal area backfill, we recommend the exposed subgrade soils be scarified to a depth of 9 inches, adjusted in moisture content and compacted to at least 95% of the materials standard Proctor maximum dry density. The moisture content of the scarified soils should be adjusted to be within the range of ±2% of standard Proctor optimum moisture content at the time of compaction. Fill and removal area backfill soils required to develop the site should consist of approved, low -volume -change (LVC) soils free from organic matter, debris and other objectionable materials. Based on results of the completed laboratory testing, it is our opinion the natural site silty sand could be used as fill and backfill provided the proper moisture content is developed in those materials at the time of placement and compaction. If required, imported soils should consist of approved LVC and relatively impervious soils free from organic matter and debris. Site fill and backfill should contain a minimum of 25% fines in order to reduce the ability of those materials to pond and transmit water. Suitable fill and backfill soils should be placed in loose lifts not to exceed 9 inches thick, adjusted in moisture content and compacted as recommended for the scarified soils above. Care should be taken to avoid disturbing all subgrade soils prior to placement of any overlying improvements. Soils which are allowed to dry out or become wet and softened or disturbed by the construction activities should be removed and replaced or reworked in place prior to concrete placement. Geotechnical Subsurface Exploration Report Proposed Addition to Existing Residence (Lot 1, Block 3, Casagrande Estates) 9712 Sierra Vista Road, Longmont, Colorado Soilogic # 21-1287 6 Foundations Based on the materials encountered in the completed site boring and results of laboratory testing, it is our opinion the proposed lightly -loaded garage/breezeway addition could be supported by a continuous spread footing and isolated pad and/or a monolithic/thickened- edge slab foundation system bearing on loose to medium dense silty sand with no to low swell potential or properly placed and compacted fill developed as outlined above. For design of footing foundations bearing on natural, undisturbed silty sand or suitable fill compacted to at least 95% of the materials standard Proctor maximum dry density, we recommend using a maximum net allowable soil bearing pressure of 1,500 psf. Exterior footings shall be placed a minimum of 30 inches below finished adjacent exterior grade to provide frost protection. We recommend formed strip footings have a minimum width of 12 inches and isolated pad foundations have a minimum width of 24 inches in order to facilitate construction and reduce the potential for development of eccentrically loaded footings. Actual footing widths should be designed by a structural engineer. Backfill placed adjacent to foundation walls should consist of approved LVC soils free from organic matter, debris and other objectionable materials. The site silty sand and/or similar approved LVC import materials could be used as foundation wall backfill. Foundation wall backfill soils should be placed in loose lifts not to exceed 9 inches thick, adjusted in moisture and compacted as previously outlined in the "Site Development" section of this report. Excessive lateral stresses can be imposed on foundation walls when using heavier mechanical compaction equipment. We recommend compaction of unbalanced foundation wall backfill soils be completed using light mechanical or hand compaction equipment. For design of footing foundations and foundation walls to resist lateral movement, a passive equivalent fluid pressure value of 275 pcf could be used. The top 30 inches of subgrade could be considered a surcharge load but should not be used in the passive resistance calculations. A coefficient of friction of 0.45 could be used between foundation and floor slab concrete and the bearing soils to resist sliding. The recommended passive equivalent fluid pressure value and coefficient of friction do not include a factor of safety. Geotechnical Subsurface Exploration Report Proposed Addition to Existing Residence (Lot 1, Block 3, Casagrande Estates) 9712 Sierra Vista Road, Longmont, Colorado Soilogic # 21-1287 7 Care should be taken to ensure the addition foundations will not be supported on any disturbed or previously placed backfill soils associated with construction of the existing residence. If/where encountered, extending footing foundations through existing fill to bear on natural soils at greater depth or overexcavation/backfill procedures would be required in these areas to develop suitable foundation bearing. Structurally spanning the existing residence backfill zone could also be considered. Soilogic estimates settlement of new spread footing or monolithic/thickened-edge slab foundation systems designed and constructed as outlined above and resulting from the assumed structural loads would be less than 1 inch. If/where additional loads are imposed on existing footing foundations, some additional settlement of those footings will occur subsequent to construction of the addition. Assuming typical residential construction footing widths, we estimate additional settlement of the existing footing foundations of 1/2 inch or less will occur subsequent to construction as a result of the additionally -imposed loads. Some differential settlement should be anticipated between the existing and any newly -constructed footings. An allowance for some differential movement should be included in the design. Similarly, some differential settlement should be expected between existing footing foundations not subjected to additionally -imposed loads and those that are subjected to additionally -imposed loads. Based on the subsurface conditions encountered and uniform loading anticipated, we expect differential settlement across the existing structure would be limited to 1/2 inch or less. Even limited differential settlement can result in some cosmetic distress to existing residence finishes and some repair efforts may be required subsequent to improvement construction and loading. The existing basement foundation walls may be subjected to additional lateral earth pressure loads imposed by the breezeway addition footing foundations. Soilogic recommends the existing foundation system and basement walls be evaluated by a qualified structural engineer prior to design and construction of the addition to ensure the walls will be able to withstand additional surcharge loads. If it is determined the residence is not supported by conventional spread footing foundations after additional investigation, alternative foundation systems may be required. We would be happy to provide alternative foundation design criteria for support of the proposed addition should the residence be determined to be supported by some type of deep foundation system. Geotechnical Subsurface Exploration Report Proposed Addition to Existing Residence (Lot 1, Block 3, Casagrande Estates) 9712 Sierra Vista Road, Longmont, Colorado Soilogic # 21-1287 8 Crawl Space Construction As a precaution, we recommend a perimeter drain system or systems be constructed around the crawl space area (if any) to help reduce the potential for water infiltration into the crawl space area of the addition and/or the development of hydrostatic pressures behind the foundation walls. The perimeter drain system(s) should consist of a 4 -inch diameter perforated drain pipe surrounded by a minimum of six (6) inches of free -draining gravel. A filter fabric should be considered around the free -draining gravel or perforated pipe to reduce the potential for an influx of fine-grained soils into the system. The invert of the drain pipe, at its high point, should be placed at approximate foundation bearing level, run around the interior or exterior perimeter of the crawl space area with a minimum slope of '/8 -inch per foot to facilitate efficient water removal and should discharge to a sump pump and pit system. Care should be taken at the time of perimeter drain installation to avoid disturbing those soils providing support to the addition footing foundations (extending down at a 1:1 slope from the bottom edges of the footings). As an additional precaution, we recommend a vapor barrier be installed in crawl space area in order to help maintain in -situ soil moisture conditions and reduce the potential for migration of soil moisture into the crawl space area. Subgrades in the crawl space area should be sloped to drain to the perimeter drain system. The owner/client should consider consulting with a mold prevention specialist for additional precautions that could be implemented to reduce the potential for development of moist air conditions in the crawl space area of the addition. Floor Slabs At -grade floor slabs could be supported directly on reconditioned silty sand with no to low swell potential and/or properly moisture conditioned and compacted fill developed as outlined in the "Site Development" section of this report. Care should be taken to maintain the proper moisture content and avoid disturbing all floor slab subgrade soils prior to concrete placement. The exposed floor slab soils should not be left exposed for extended periods of time. In the event that the subgrade soils are allowed to dry out or if rain, snowmelt or water from any source is allowed to infiltrate those Geotechnical Subsurface Exploration Report Proposed Addition to Existing Residence (Lot 1, Block 3, Casagrande Estates) 9712 Sierra Vista Road, Longmont, Colorado Soilogic # 21-1287 9 materials, reworking of the subgrade soils or removal/replacement procedures may be required. If/where conventional spread footing construction is utilized, floor slabs should be designed and constructed as floating slabs, separated from foundation walls, columns and plumbing and mechanical penetrations by the use of block outs or appropriate isolation material. Additionally, we recommend any partition walls supported above slabs -on -grade be constructed as floating walls to help reduce the potential for differential slab -to - foundation movement causing distress in upper sections of the structure. A minimum 11/2 - inch void space is recommended beneath all partition walls. Special attention to door and stair framing, drywall installation and trim carpentry should be taken to isolate those elements from the floor slabs, allowing for some differential floor slab to foundation movement to occur without transmitting stresses to the overlying structure. If a monolithic/ thickened -edge slab -on -grade foundation system will be employed, floating wall construction would not be required. Depending on the type of floor covering and floor covering adhesive used in finished slab - on -grade areas, a vapor barrier may be required immediately beneath the floor slabs in order to maintain flooring product manufacturer warranties. A vapor barrier would help reduce the transmission of moisture through the floor slab. However, the unilateral moisture release caused by placing concrete on an impermeable surface can increase slab curl. The amount of slab curl can be reduced by careful selection of an appropriate concrete mix, however, slab curl cannot be eliminated. We recommend the owner, architect and flooring contractor consider the performance of the slab, in conjunction with the proposed flooring products to help determine if a vapor barrier will be required and where best to position the vapor barrier in relation to the floor slab. Additional guidance and recommendations concerning slab -on -grade design can be found in American Concrete Institute (ACI) section 302. Drainage Positive drainage is imperative for satisfactory long-term performance of the residence, proposed addition and associated site improvements. We recommend positive drainage be developed away from the residence and residence addition during construction and Geotechnical Subsurface Exploration Report Proposed Addition to Existing Residence (Lot 1, Block 3, Casagrande Estates) 9712 Sierra Vista Road, Longmont, Colorado Soilogic # 21-1287 10 maintained throughout the life of the site improvements, with twelve (12) inches of fall in the first 10 feet away from the residence and addition. Shallower slopes could be considered in hardscape areas. In the event that poor or negative drainage develops adjacent to the residence and/or addition over time, the original grade and associated positive drainage outlined above should be immediately restored. Care should be taken in the planning of landscaping to avoid features which could result in the fluctuation of the moisture content of the foundation bearing and/or flatwork subgrade soils. We recommend watering systems be placed a minimum of 5 feet away from the perimeter of the site structure and be designed to discharge away from all site improvements. Gutter systems should be considered to help reduce the potential for water ponding adjacent to the building with the gutter downspouts, roof drains or scuppers extended to discharge a minimum of 5 feet away from structural, flatwork and pavement elements. Water which is allowed to pond adjacent to site improvements can result in unsatisfactory performance of those improvements over time. GENERAL COMMENTS This report was prepared based upon the data obtained from the completed site exploration, laboratory testing, engineering analysis and any other information discussed. The completed boring provides an indication of subsurface conditions at the boring location only. Variations in subsurface conditions can occur in relatively short distances away from the boring. This report does not reflect any variations which may occur across the site or away from the boring. If variations in the subsurface conditions anticipated become evident, the geotechnical engineer should be notified immediately so that further evaluation can be completed and when warranted, alternative recommendations provided. The scope of services for this project does not include either specifically or by implication any biological or environmental assessment of the site or identification or prevention of pollutants or hazardous materials or conditions. Other studies should be completed if concerns over the potential of such contamination or pollution exist. The geotechnical engineer should be retained to review the plans and specifications so that comments can be made regarding the interpretation and implementation of our Geotechnical Subsurface Exploration Report Proposed Addition to Existing Residence (Lot 1, Block 3, Casagrande Estates) 9712 Sierra Vista Road, Longmont, Colorado Soilogic # 21-1287 11 geotechnical recommendations in the design and specifications. The geotechnical engineer should also be retained to provide testing and observation services during construction to help determine that the design requirements are fulfilled. This report has been prepared for the exclusive use of our client for specific application to the project discussed and has been prepared in accordance with the generally accepted standard of care for the profession. No warranties express or implied, are made. The conclusions and recommendations contained in this report should not be considered valid in the event that any changes in the nature, design or location of the project as outlined in this report are planned, unless those changes are reviewed and the conclusions of this report modified and verified in writing by the geotechnical engineer. We appreciate the opportunity to be of service to you on this project. If you have any questions concerning the enclosed information or if we can be of further service to you in any way, please do not hesitate to contact us. Very Truly Yours, Soilogic, Inc.

In low permeability soils, the accurate determination of groundwater levels may not be possible with only short-term observations. DESCRIPTIVE SOIL CLASSIFICATION: Soil classification is based on the Unified Classification System. Coarse Grained Soils have more than 50% of their dry weight retained on a #200 sieve; their principal descriptors are: boulders, cobbles, gravel or sand. Fine Grained Soils have less than 50% of their dry weight retained on a #200 sieve; they are principally described as clays if they are plastic, and silts if they are slightly plastic or non -plastic. Major constituents may be added as modifiers and minor constituents may be added according to the relative proportions based on grain size. In addition to gradation, coarse -grained soils are defined on the basis of their in -place relative density and fine-grained soils on the basis of their consistency.
