The results of our exploration, laboratory testing and engineering evaluation indicate the soils underlying this site have low expansive characteristics. Potential vertical movement on the order of 1-2 inches was estimated at the existing grade level for average moisture conditions. The proposed structure may be supported by spread or strip footings bearing a minimum of three (3) feet below finished grade at the basement level, on compacted in-situ soils. Design parameters for the foundations are included in this report. Groundwater seepage was encountered in the borings at the time of our field exploration. Detailed descriptions of subsurface conditions, engineering analysis, and design recommendations are included in this report. Terradyne Engineering, Inc.

Colorado 1 1.0 INTRODUCTION This report presents the results of our subsurface exploration and foundation analysis for the proposed residence at 3205 Robb St in Wheat Ridge, Colorado. The object of this investigation was to evaluate the physical properties of the soils underlying the site in order to provide recommendations for foundation, and retaining wall design, slab support and related earthwork for the structures. This geotechnical investigation was authorized by Workshop Denver. 2.0 PROJECT DESCRIPTION Terradyne understands that the proposed Residence will be a one to two story structure with basement, with a footprint of not more than 4000 square feet. If the final construction plans vary from what has been assumed, please contact Terradyne for further evaluation as the revisions may affect the recommendations provided in this report. 3.0 PURPOSE AND SCOPE OF SERVICES The purpose of our geotechnical investigation was to evaluate the subsurface and groundwater conditions of the site and provide geotechnical engineering recommendations for the design and construction of the residence. Our scope of services includes the following: 1) Drilling and sampling of one boring 13-1 to a depth of 25 feet; 2) Evaluation of the in-place conditions of the subsurface soils through field penetration tests; 3) Observation of the groundwater conditions during drilling operations; 4) Performing laboratory tests such as Atterberg limits, moisture content tests, free swell/consolidation tests; 5) Review and evaluation of field and laboratory tests; 6) Compilation, generalization and analysis of the field and laboratory data according to the project requirements; 7) Estimation of potential vertical heave; 8) Preparation of recommendations for the design and construction of the structures; 9) Consultations with Prime Professionals and members of the design team on findings and recommendations and the preparation of a written geotechnical engineering report for their use in the preparation of design and construction documents. The Scope of Services does not include an environmental assessment of the presence or absence of wetlands and/or hazardous or toxic materials in the soil, surface water, groundwater, or air, in the proximity of this site. Any statements in this report or on the boring logs regarding odors, colors or unusual or suspicious items or conditions are strictly for the information of the client. City of Wheat Ridge Building Division Terradyne Engineering, Inc. C201018-1 Proposed Residence at 3205 Robb St, neatRidze. Colorado 2 4.0 SITE CONDITIONS The site for the proposed residence is located at 3205 Robb St, in Wheat Ridge, Colorado. The site is generally flat and is located on a vacant lot within a developed area. The site is bordered by adjoining property to the west, adjoining lot on the north, W 32nd Ave to the south, and Robb St. is to the east of the property. The boring location was established in the field by information provided by the client. 5.0 GEOTECHNICAL INVESTIGATION The field exploration to determine the engineering characteristics of the subsurface materials included a reconnaissance of the project site, drilling the boring, performing standard penetration tests and obtaining samples using Modified California sampler. One (1) soil test boring was drilled at the site. Boring B-1 was drilled to a maximum depth of 25 feet. Boring location at the lot was selected based on information provided by the client and established in the field by the drilling crew. An approximate boring location plan is shown on Figure 1 in the Appendix. The boring was performed with a drilling rig equipped with a rotary head. Conventional solid stem augers were used to advance the hole and samples of the subsurface materials were obtained using a Modified California sampler and standard 4.0 -inch augers. The samples were identified according to boring number and depth, encased in polyethylene plastic wrapping to protect against moisture loss, and transported to our laboratory. 5.1 Field Tests and Measurements Penetration Tests: During the sampling procedures, standard penetration tests were performed in the boring in conjunction with split -barrel sampling (ASTM 1586). The standard penetration value (N) is defined as the number of blows of a 140 -pound hammer, falling thirty inches, required to advance the split -spoon sampler one foot into the soil. The sampler is lowered to the bottom of the drill hole and the number of blows recorded for each of the two successive increments of six inches penetration. The "N' value is obtained by adding the second and third incremental numbers. The results of the standard penetration tests indicate the relative density and comparative consistency of the soils, and thereby provide a basis for estimating the relative strength and compressibility of the soil profile components. Water Level Measurements: Water level was noticed in Terradyne's soil boring during and after completion of drilling operations and is noted on the boring log. hi relatively pervious soils, such as sandy soils, the indicated elevations are considered reliable groundwater levels. hi relatively impervious soils, an accurate determination of the groundwater elevation may not be possible even after several days of observation. Seasonal variations, temperature and recent rainfall conditions may influence the level of the groundwater table and the volume of water encountered will depend on the City of permeability of the soils.

The test boring log should be consulted for specific information at the boring locations. Groundwater was encountered in our boring during drilling operations at a depth of 15 ft below existing grade on boring 131. However, groundwater levels will fluctuate with seasonal climatic variations and changes in the land use. The low permeability of the soils may require several days for groundwater to enter and stabilize in the boreholes. It is not unusual to encounter shallow groundwater during or after periods of rainfall. Surface water tends to percolate through the surface until it encounters a relatively imperious layer. 6.0 FOUNDATIONS ON EXPANSIVE SOIL There are many plastic clays that swell when water is added to them and shrink when water is removed. Foundations constructed on these clays are subjected to large uplifting forces caused by the swelling. Two factors contribute to potential shrink -swell problems within a building site. Problems can arise if a) the soil has expansive or shrinkage properties or b) environmental conditions cause the moisture levels in the soil to change. Evaluation of the Shrink -Swell Potential of the Soils: Subsurface sampling, laboratory testing and data analysis is used to evaluate the shrink -swell potential of the soils under the foundations. The Mechanism of Swelling: The mechanism of swelling in expansive clays is influenced by a number of factors. The expansion in clays is a result of changes in the soil -water system that disturbs the internal stress equilibrium. Clay particles have negative electrical charges on their surfaces and positively charged ends. The negative charges are balanced by actions in the soil - water and give rise to an electrical interparticle force field. In addition, adsorptive forces exist between the clay crystals and water molecules, and Van Der Waals surface forces exist between particles. Thus, there exists an internal electro -chemical force system that must be in equilibriumcity of Wheat Ridge Terradyne Engineering, Inc. C201 MTIng Division Proposed Residence at 3205 Robb St, neatRidze. Colorado 6 with the externally applied stresses and capillary tension in the soil water. If the soil -water chemistry is altered, either by changing the amount of water or chemical composition in the soil, the inter -particle force field will change. If the change in internal forces is not balanced by a corresponding change in the state of stress, the particle spacing changes until equilibrium is reached. This change in particle spacing manifests itself as a shrinkage or swelling. Antecedent Rainfall Ratio: This is defined as the total monthly rainfall for the current and previous months prior to laying the slab, divided by twice the average monthly rate measured for the period. The intent of this ratio is to give a relative measure of ground moisture conditions at the time the slab is placed. Thus, if a slab is placed at the end of a wet period, the slab shall be expected to experience some loss of support around the perimeter as the wet soil begins to dry out and shrink. The opposite effect could be anticipated if the slab is placed at the end of an extended dry period; as the wet season occurs, uplift around the perimeter may occur as the soil at the edge of the slab gains in moisture content. Age of Slab: The length of time since the slab was cast provides an indication of the type of swelling the soil profile may have beneath the slab. Initial Moisture Condition and Moisture Variation: A volume change in an expansive soil mass is the result of increases or decreases in water content. The initial moisture content influences the swell and shrink potential of a soil. However, moisture content alone is useless as an indicator or predictor of shrink -swell potential. The relationship between moisture content and other soil characteristics, such as the Plastic Limit and Liquid Limit, must also be known. If the moisture content is below or near the Plastic Limit, the soils may have a high potential to swell. Expansive soils with Liquidity Index in the range of 0.20 to 0.40 tend to experience little additional swell. The availability of water in an expansive soil profile is influenced by many environmental and manmade factors. Generally, the upper few feet of the profile are subjected to the widest ranges of moisture variation, and are the least restrained from movement by overburden. This upper stratum of the profile is referred to as the active zone. Moisture variation in the active zone of a natural soil profile is affected by climatic cycles at the surface and fluctuating groundwater levels at the lower moisture boundary. The superficial boundary moisture conditions are changed by placing a barrier, such as a building floor slab or pavement, between the soil and atmospheric environment. Other causes of moisture variation result from altered drainage conditions or manmade sources of water, such as irrigation or leaky plumbing. The latter factors are difficult to quantify and incorporate into 2 LIQUIDITY INDEX— NATURAL WATER CONTENT —PLASTIC LIMIT LIQUID LIMIT — PLASTIC LIMIT Terradyne Engineering, Inc. City of Wheat Ridge Building Division C201018-1 Proposed Residence at 3205 Robb St, neatRidze. Colorado 7 the analysis but shall be controlled to the extent possible for each situation. For example, proper drainage and attention to landscaping are simple means of minimizing moisture fluctuations near structures and shall always be taken into consideration. Manmade Conditions That Can Be Altered: There are a number of factors that can influence whether a soil might shrink or swell and the magnitude of this movement. For the most part, the owner and/or designer have some control over whether these factors can be avoided, and if not avoided, the degree to which these factors may influence the shrink -swell process. Lot Drainage: How a lot is graded affects the accumulation of surface water around the slab. Most builders are aware of the importance of grading the soil away from the structure so that rainwater does not collect and pond adjacent to the foundation. If allowed to accumulate next to the foundation, water may infiltrate the expansive soils underlying the foundation, which could cause the foundation to settle. Similarly, runoff from surface water drainage patterns and swales must not collect adjacent to the foundation. Tonouaphy: As it swells, soil heaves perpendicularly to the ground surface or slope, but as it shrinks, it recedes in the direction of gravity and gradually moves downslope in a sawtooth fashion over a number of shrink -swell cycles. In addition to this shrink -swell influence, soil will exhibit viscoelastic properties and creep downhill under the steady influence of the weight of the soil. Therefore, to avoid a structure constructed on this slope from moving downhill with the soil, it must be designed to compensate for this lateral soil influence. Pre -Construction Vegetation: A large amount of vegetation, especially large trees, on a site prior to construction may have desiccation at the site. Constructing over a desiccated soil can produce some dramatic instances of heave and associated structural distress and damage as it becomes wet. Post -Construction Vegetation: The type, amount, and location of vegetation that has grown since construction can cause localized desiccation. Planting trees or large shrubs near a building can result in the loss of foundation support as the vegetation robs moisture from the foundation soil. Conversely, the opposite effect can occur ifflowerbeds or shrubs are planted next to the foundation and these beds are kept well -watered or flooded. This practice can result in swelling of the soil around the perimeter where the soil remains wet. Summation: It is beyond the scope of this investigation to do more than point out the factors that may influence the amount and type of swell a slab -on -grade foundation may be subjected to during its lifetime. The design engineer must be aware of these factors in developing his design, using his engineering experience and judgment as a guide. City of Wheat Ridge g Division Terradyne Engineering, Inc. C201018-1 Proposed Residence at 3205 Robb St, neatRidze. Colorado 8 7.0 DESIGN ENGINEERING ANALYSIS Foundation Design Considerations: Review of the boring and test data indicates that the factors presented on the following page will affect the foundation design and construction at this site: 1) The site is underlain by subsoils of low expansive potential at shallow depths. Structures supported at shallow depths will be subjected to potential vertical movements on the order of 1-2 inches. 2) The strengths of the underlying soils are adequate to support shallow or deep foundations. 3) Groundwater was encountered in our borings at the time of the subsurface exploration phase at a depth of 15 feet below existing grade on boring Bl. Structural Information: Based on the information provided, it is understood that the proposed structure will be a one to two story residence. These structures are expected to create moderately low loads to be carried by the foundation systems. These structures will utilize wood frame construction and brick or stucco exterior walls. It is assumed that the maximum column loads will not exceed 5 kips, while maximum exterior wall loading will be in the range of one kip per foot. Vertical Movements: The potential vertical heave for slab -on grade construction at the location has been estimated utilizing the liquid limits, plasticity indices, and in-situ moisture contents for soils in the seasonally active zone, estimated to be about twenty to twenty-five feet in the project area The estimated potential vertical heave value provided is based on the proposed floor system applying a sustained surcharge load of approximately one pound per square inch on the subgrade materials. Potential vertical movements on the order of 1-2 inches may be anticipated for average soil moisture conditions. The finish grade elevation was assumed to be '/2 to one foot above the existing grade level. Select structural fill shall be used to raise the elevation by'/2 to one foot. If the existing grade has to be raised to attain the finish grade elevation, select fill shall be placed, compacted and tested for compaction compliance by Terradyne 8.0 FOUNDATION RECOMMENDATIONS The type and depth of foundation suitable for a given structure primarily depends on several factors: the subsurface conditions, the function of the structure, the loads it may carry and the cost of the foundation. Additional considerations may include acceptable performance criteria set by the owner, architect, or structural designer with respect to vertical and differential movements that the structure can withstand without damage. Based on these conditions and the engineering design analysis spread or strip type footings bearing on undisturbed in-situ soils at a minimum depth of 3 feet below finished grade at the basement level can be used. Either a slab on grade or a structurally suspended slab 919 of Wheat Ridge Terradyne Engineering, Inc. CA'U�q Division Proposed Residence at 3205 Robb St, neatRidze. Colorado be used. 8.1 Spread-Tvpe Footings 9 Spread or strip type footings at a minimum depth of three (3) feet below finished grade at the basement level bearing on compacted in situ soils can be used to support the structure. An allowable soil bearing pressure of 2,000 pounds per square foot is recommended for the design of spread or strip type footings at the basement level. In order to minimize the sensitivity of the structure to differential movement, the footings and walls should be reinforced to allow for a degree of load re -distribution should a localized zone of the supporting soils become saturated. Stem walls should either be positively separated from the floor slabs or reinforced to prevent cracking at the slab stem wall interface. Uplift resistance of shallow foundations formed in an open excavation should be taken as the weight of the foundation and soil above it. For design purposes, the uplift resistance should be based on total unit weights of 110 and 150 lbs. per cubic foot (pcf) for soil and concrete respectively. In areas where ground water is anticipated or in areas prone to flooding, the uplift resistance should be based on submerged unit weights of 57 and 87.5 pounds per cubic foot (pcf) for soil and concrete respectively. A factor of safety of 2 is recommended for sustained loading conditions, and 1.5 for transient loading conditions. 8.2 Foundation Construction Guidelines Significant moisture increase in the in-situ soils could create additional and/or excessive movements in the site. Accordingly, the site drainage and moisture protection provisions, recommended in this report are critical design considerations. Prior to placing concrete, all bearing surfaces must be cleared of all loose material. Disturbed material may only be re -compacted with guidance from, and after contacting Terradyne. To verify the soil conditions and soil bearing capacity, it is required that an open hole observation be performed. The entire excavation must be dug down to final grade prior to the observation. If potentially expansive clay, deleterious material, or other unsuitable conditions are found, additional over -excavation of some or the entire site may be required — replacing inadequate soils with acceptable materials. Revised foundation recommendations such as the use of drilled piers may also be required at that time. We recommend the foundation subgrade be inspected for adequacy before concrete placement. Ensure that the requirements contained herein are reflected in any construction plans developed for this site. Floor Slabs: Should the owner choose to use a structurally suspended slab, a positive void space of at least 6 inches shall be provided beneath the floor slab. The basement shall be designed with a positive drainage flow so that water will not accumulate in the basement. Excavated on-site mat&ivlof Wheat Ridge Terradyne Engineering, Inc. C21WMWgbivision Proposed Residence at 3205 Robb St, neatRidze. Colorado 10 that is free of deleterious material may be used to raise the grade in the basement area. This material shall be compacted to at least 95 percent of the ASTM D 698 maximum dry density at moisture contents that range from optimum to four (4) percent above the optimum, and the compacted soil should be tested by Terradyne to verify the moisture content and density for each compacted six (6) inch lift of material. 8.3 Slab -on -Grade Construction The Slab Performance Risk at this site is judged to be low. However, it must be understood, that changes in the water content of these soils may cause the soil to swell or shrink, which may cause movement or cracking of slabs. Potential vertical movement on the order of 1-2 inches is anticipated at the project site. Slabs should bear on proof -rolled and re -compacted materials. A proof -roll of the subgrade shall be observed by the geotechnical engineer's representative. They must not bear on gravel or other materials which may allow the migration of water below the slabs. If the on-site soils are not acceptable, it is preferable to bear slabs on non -expansive imported materials. This will minimize the transfer and retention of water below the slab. Materials with a Liquid Limit below 30 and a Plasticity Index between 10 and 15 are preferred. Slabs shall be isolated from foundation components by slip joints constructed to allow the independent movement of the slab. Slabs shall also be separated from any utility components by isolation joints. Mechanical equipment resting on slabs must be fitted with expandable/collapsible sections in order to allow movement of the slab without damage to the equipment or to the structure. Non-bearing partition walls must be constructed with a minimum of 2 inches of float to allow for movement of the slab without damaging any part of the structure. All doors shall be constructed with at least 1 -inch gap at floor level. It is the owner's responsibility to monitor and maintain all floats and gaps as necessary. If additional information on float is needed, please contact Terradyne. Slabs must be appropriately reinforced to resist the anticipated loads as well as the effects of the supporting soils. Floor slabs must also be scored in accordance with the American Concrete Institute (ACI) recommendations in order to control cracking of the slab due to shrinkage or other factors. These scores should be a maximum of 12 feet apart. 8.4 Utilities Utilities that project through slab -on -grade floors shall be designed with either some degree of flexibility or with sleeves in order to prevent damage to these lines should vertical movements occur. City of Wheat Ridge Terradyne Engineering, Inc. C20JWWidg Division Proposed Residence at 3205 Robb St, neatRidze. Colorado 11 8.5 Contraction, Control and/or Expansion Joints Contraction, control and/or expansion joints shall be designed and placed in various portions of the structure. Properly planned placement of these joints will assist in controlling the degree and location of material cracking that occurs due to soil movements, material shrinkage, thermal affects and other related structural conditions. 8.6 Lateral Earth Pressure Some retaining walls may be needed at this site. The equivalent fluid density values were evaluated for various backfill materials. These values are presented in Table No. 4. Table No. 4 Backfill Material Equivalent Fluid Density, PCF Active Condition At Rest Condition Passive Condition a. Crushed Limestone 40 60 530 b. Clean Sand 40 60 360 c. Select Fill (PI < 15) 65 85 265 These equivalent fluid densities do not include the effect of seepage pressures, surcharge loads such as construction equipment, vehicular loads or future storage near the walls. If a cantilever retaining wall can tilt forward to generate "active earth pressure" condition, the values under active condition shall be used. For rigid non -yielding walls which are part of the building, the values" at rest condition" shall be used. The compactive effort shall be controlled during backfill operations. Over compaction can produce lateral earth pressures in excess of at rest magnitudes. Compaction levels adjacent to below -grade walls shall be maintained between 95 and 98 percent of standard Proctor (ASTM D698) maximum dry density. The backfill behind the wall shall be drained properly. The simplest drainage system consists of a drain located near the bottom of the wall. The drain collects the water that enters the backfill and this may be disposed of through outlets along the base of the wall. To insure that the drains are not clogged by fine particles, they shall be surrounded by a granular filter. In spite of a well - constructed toe drain, substantial water pressure may develop behind the wall if the backfill consists of clays or silts. A more satisfactory drainage system, consisting of a back drain of 12 inches to 24 inches width gravel may be provided behind the wall to facilitate to drainage. The maximum toe pressure for wall footings founded a minimum depth of 36 inches into the clay soils shall not exceed 1,200 pounds per square foot. An adhesion value of 320 pounds per square foot should be used to check against sliding for wall footings bearing on clay. City of Ulk-Pidge Terradyne Engineering, Inc.

Colorado 12 9.0 CONSTRUCTION GUIDELINES 9.1 Construction Monitoring As Geotechnical Engineer of Record for this proiect, Terradvne, shall be involved in monitoring the foundation installation and earthwork activities. The performance of anv foundation system is not only dependent on the foundation design, but is strongly influenced by the quality of construction. Prior to construction, please contact our office so that a Foundation and Earthwork Monitoring Plan can be incorporated into the Proiect Quality Control Program. 9.2 Site Preparation In any areas where soil -supported floor slabs or pavement are to be constructed, vegetation and all loose or organic material shall be stripped and removed from the site. Subsequent to stripping operations, the subgrade shall be proofrolled to identify soft zones. Any soft zone detected shall be removed to afirm subgrade soils and replaced with compacted suitable soils to reach subgrade level. Upon the acceptance of proofrolling operations the subgrade shall be scarified to a minimum depth of 8 inches, moisture conditioned and compacted to a 95 percent of maximum dry density as determined by ASTM D 698, between optimum and 4 percentage points above of optimum moisture content The exposed subgrade shall not be allowed to dry out prior to placing structural fill. Select fill material used at this site shall be clayey sand (SC), lean clay with gravel (CL) or clayey gravel (GC) with maximum liquid limit of 35 percent and plasticity index (Pl) between 5 and 20. The fill shall be compacted to at least 95 percent of the maximum dry density as determined by ASTM D 698, within f 2 percentage points of optimum moisture content 9.3 Drainage Groundwater seepage was encountered in our boring during drilling operations. However, minor groundwater seepage may be encountered within the proposed building foundation and grading excavations at the time of construction, especially after periods of heavy precipitation. Small quantities of seepage may be removed by conventional sump and pump methods of dewatering. 9.4 Temporary Drainage Measures Temporary drainage provisions shall be established to minimize water runoff into construction areas. If standing water does accumulate, it shall be removed by pumping as soon as possible. Adequate protection against sloughing of soils shall be provided for workers and inspectors entering the excavations. This protection shall meet OSHA and other applicable building codes. 9.5 Groundwater In areas where significant cuts (2 -feet or more) are made to establish final grades for building pads, attention shall be given to possible seasonal water seepage that could occur through natural cracks City of Terradyne Engineering, Inc. C201018-1 idge Building Division Proposed Residence at 3205 Robb St, neatRidze. Colorado 13 and fissures in the newly exposed stratigraphy. Subsurface drains may be required to intercept seasonal groundwater seepage. The need for these, or other dewatering devices, on building pads shall be carefully addressed during construction. Our office could be contacted to visually inspect final pads to evaluate the need for such drains. Groundwater seepage may occur several years after construction if the rainfall rate or drainage changes in the vicinity of the project site. If seepage runoff occurs towards the building, an engineer shall be contacted to evaluate its' effect and determine whether French drains are required at the location. 9.6 Control Testing and Field Observation Subgrade preparation and select structural fill placement shall be monitored by the project geotechnical engineer or his representative. As a guideline, at least one in-place density test shall be performed for each 2,500 square feet of compacted surface lift. A minimum of two density tests shall be performed on the subgrade or per lift of compaction. Any areas not meeting the required compaction shall be re -compacted and retested until compliance is met. 9.7 Earthwork and Foundation Acceptance Exposure to the environment may weaken the soils at the foundation bearing level if the excavation remains open for long periods of time. Therefore, it is recommended that all foundation excavations be extended to final grade and the footings constructed as soon as possible to minimize potential damage to bearing soils. The foundation bearing level shall be free of loose soil, ponded water or debris sand, and shall be inspected and approved by the geotechnical engineer or his representative prior to concreting. Foundation concrete shall not be placed on soils that have been disturbed by rainfall or seepage. If the bearing soils are softened by surface water intrusion during exposure or by desiccation, the unsuitable soils must be removed from the foundation excavation and replaced prior to placement of concrete. Subgrade preparation and fill placement operations shall be monitored by the geotechnical engineer or his representative. As a guideline, at least one in-place density test shall be performed for each 2,500 square feet of compacted surface lift. Any areas not meeting the required compaction shall be recompacted and retested until compliance is met. 10.0 DRAINAGE AND MAINTENANCE Final drainage is important for the performance of the proposed structures and pavement. Landscaping, plumbing, and downspout drainage is also important It is vital that all roof draialf of e idge Terradyne Engineering, Inc. Ci01l �I8 �i. si wmg vion Proposed Residence at 3205 Robb St, neatRidze. Colorado 14 be transported away from the building so that water does not pond around it, which can result in a soil volume change underneath the building. Plumbing leaks shall be repaired as soon as possible in order to minimize the magnitude of a moisture change under the slab. Large trees and shrubs shall not be planted in the immediate vicinity of the structures, since root systems can cause a substantial reduction in soil volume in the vicinity of the trees during dry periods. Adequate drainage shall be provided to reduce seasonal variations in moisture content of foundation soils. All pavement and sidewalks within 10 -feet of the structures shall be sloped away from the structures to prevent ponding of water around the foundations. Final grades within 10 -feet of the structure shall be adjusted to slope away from structures preferably at a minimum slope of 3 percent. Maintaining positive surface drainage throughout the life of the structure is essential. In areas with pavement or sidewalks adjacent to the new structure, a positive seal must be provided and maintained between the structures and the pavement or sidewalk to minimize seepage of water into the underlying supporting soils. Post -construction movement of pavement and flat -work is not uncommon. Maximum grades practical shall be used for paving and flatwork to prevent areas where water can pond. In addition, allowances in final grades shall take into consideration post construction movement of flatwork, particularly if such movement would be critical. Normal maintenance shall include inspection of all joints in paving and sidewalks, etc. as well as re -sealing where necessary. There are several factors related to civil and architectural design and/or maintenance that can significantly affect future movements of the foundation and floor slab systems. 1. Where positive surface drainage cannot be achieved by grading the ground surface adjacent to the buildings, a complete system of gutters and downspouts shall carry runoff water a minimum of 10 -feet from the completed structures. 2. Planters located adjacent to the structures shall preferably be self-contained. Sprinkler mains shall be located a minimum of five feet from the building line. 3. Planter box structures placed adjacent to the building shall be provided with a means to assure concentrations of water do not infiltrate the subsoils stratigraphy. 4. Large trees and shrubs shall not be planted closer to the foundations than a horizontal distance equal to roughly their mature height due to their significant moisture demand upon maturing. 5. Moisture conditions shall be maintained "constant' around the edge of the slabs. Ponding of water in planters, in unpaved areas, and around joints in paving and sidewalks can cause slab movements beyond those predicted in this report.

Roof drains shall discharge on pavement or be extended away from the structures. Ideally, roof drains shall discharge to storm sewers by closed pipe.

Since granular bedding backfill is used for most utility lines, the backfilled trench shall be prevented from becoming a conduit and allowing an access for surface or subsurface water to travel toward the new structures. Concrete cut-off collars or clay plugs shall be provided where utility lines cross building lines to prevent water from traveling in the trench backfill and entering beneath the structures. The potential vertical heave values estimated and stated under "Vertical Movements" are based on the provision that positive drainage shall be maintained to divert water away from the building and adjacent pavement. If this drainage is not maintained, the wetted front may occur below the assumed fifteen feet depth, and the resulting vertical heave may be 2 to 3 times greater than the stated values shown in this report. Utility leaks may also cause similar high movements to occur. 11.0 LIMITATIONS The analysis and recommendations submitted in this report are based upon the data obtained from the one (1)boring drilled at the site. This report may not reflect the exact variations of the soil conditions across the site. The nature and extent of variations across the site may not become evident until construction commences. If variations appear evident, it will be necessary to re- evaluate our recommendations after performing on-site observations and tests to establish the engineering significance of any variations. The project geotechnical engineer should review the final plan for the proposed building so that he may determine if changes in the foundation recommendations are required. The project geotechnical engineer declares that the findings, recommendations or professional advice contained herein have been made and this report prepared in accordance with generally accepted professional engineering practice in the fields of geotechnical engineering and engineering geology. No other warranties are implied or expressed. This report is valid until site conditions change due to disturbance (cut and fill grading) or changes to nearby drainage conditions or for 3 years from the date of this report, whichever occurs first. Beyond this expiration date, Terradyne shall not accept any liability associated with the engineering recommendations in the report, particularly if the site conditions have changed. If this report is desired for use for design purposes beyond this expiration date, we highly recommend drilling additional borings so that we can verify the subsurface conditions and validate the recommendations in this report.

E 44 E D This letter is in reference to the retaining wall constructed by Thoutt Brothers at the above- mentioned location. Installation of the retaining wall was observed by a representative of our office during and upon completion of construction. A summary of critical items observed is listed below: 1) The leveling pad consisted of gravel material approximately 6" thick. 2) All segmental retaining wall units used to construct the mechanically stabilized earth retaining wall were Allan Block Classic units. 3) The required burial depth of the bottom of the wall appeared to be met. 4) The maximum constructed height of the retaining wall did not exceed the retaining wall design height shown on our plans. 5) Geogrid reinforcement was the correct type and appeared to have been installed correctly. 6) All reinforced backfill and block unit -fill material was found to be recycled concrete per plan. 7) The drain behind the wall was in place. Following the observations, the retaining wall appeared to be in general conformance with the Retaining Wall Design prepared by this office, project number FC08589.000, revised May 1, 2019. Final grading around the wall has not been completed. Final grading should be verified by the Civil Engineer according to the plans by TJC Limited, dated March 12, 2019, upon completion. Finishing soil or vegetation should be placed as soon as possible to protect and avoid erosion around the wall. Thank you for selecting CTLITHOMPSON for your engineering needs.

West 32nd Avenue is classified as a minor arterial in the City's Streetscape Design Manual. The Streetscape Design Manual is a document adopted by the City of Wheat Ridge, which dictates what physical improvements are required for different street classifications in conjunction with property development and the installation of curb, gutter and sidewalk. The streetscape adjacent to a development important because it defines the quality of the adjacent development and provides a pleasant pedestrian experience for residents and visitors coming to and from the future homes built there. The classification of minor arterial would usually require the following public improvements: a 6' detached sidewalk with a 6' wide amenity zone, the installation of pedestrian lights 80' on - center, street trees planted at 35' intervals, or four street trees for the frontage length of this property. Street trees must be 2.5 inches in caliper and have a branching height of no less than 8'. Streetscape trees in a planted amenity zone must be irrigated with an automatic sprinkler system; the cost of maintenance and watering would be a responsibility of the Homeowners' Association (HOA). The planting of groundcover and shrubs is required as well to soften the street edge and to add interest. It is my understanding that the installation of the required retaining wall adjacent to West 32nd Avenue complicates the prescribed installation of some of these (improvements) plant materials particularly street trees. In order for us to adequately evaluate the improvements between the existing curb face for W. 32nd Avenue and the prospective homeowner's yard, please provide a landscape plan showing the proposed improvements to this area. The proposed plantings shall be compatible with the wall design and be composed of live, drought -tolerant material. Also, please provide a "to - scale" cross section view from the curb face to the proposed south wall of the new residence. If you have any questions, please let me know. I can be reached at 303-235-2848 or mreckert(d,ci.wheatrid eg co.us. Mark Van Nattan From: Steve Nguyen Sent: Wednesday, October 17, 2018 5:06 PM To: Brian Stamm Cc: Perry Cadman; Dave Brossman; Russ Higgins; Mark Van Nattan; Tom Gray Subject: RE: Merkwood Estates Brian, As promised in getting back with you, we have assessed the curb, gutter and sidewalk and also the proposed W. 32nd Avenue retaining wall as we discussed at our meeting last week. Robb St. curb, gutter and sidewalk Staff further conducted a field visit shortly after the meeting to verify the Robb St. curb, gutter and sidewalk on the west side. This visit not only confirmed the installed type of gutter is different from the approved plans but that the sidewalk is not as wide as originally thought. The resultant product is in violation of American Disability Act (ADA) criteria, that prescribes the sidewalk be 5 feet wide for continuous runs of sidewalk as shown in the approved plans. As a result, leaving the sidewalk as is would be in violation of the ADA criteria and the City potentially subject to adverse legal action. W. 32"d Avenue Retaining wall (Lot 1) With relation to the proposed retaining wall plans, comments from a detail review will be forwarded to you and/or your staff shortly as City staff is finalizing them. Specifically for this email, I want to discuss this from a perspective of the area of disturbance along W. 32"d Avenue in the northerly right-of-way and behind the existing sidewalk. It was evident from the meeting that this is an area which both the Merkwood Estates owner and design/build staff and the City of Wheat Ridge staff are not clear on roles and responsibilities of each party. Base on the submitted plan the area of disturbance to construct the wall will be at least partially in the existing right of way, and as a result the backfill necessary to complete the structure/soil system will need to be done in accordance with City standard. With respect to the existing timber retaining wall, at least two or three top courses of timbers need to be removed for the aforementioned backfilling and installation of the approved surface material. W. 32"d Avenue — northerly sidewalk and driveway cuts The two existing drive cuts in the northern portion of the W. 32"d Avenue sidewalk will need to be converted to curb, gutter and sidewalk as these were originally there to serve the property prior to the development. Now that the site condition has changed due to new development, the drive cuts have no further purpose as there will be no roadway access from W. 32"d Avenue and, therefore, need to be closed. The City has decided to collect fees in lieu from the developer for the replacement of the drive cuts (based on Municipal Code Sec. 26-417 C & E). As the intervening segments of sidewalk between the sidewalk replacing the cuts also needs to be adjusted to the ADA mandated width, the City intends to perform this work in the coming construction season. Please let me know of any follow up questions. Thanks Steve Nguyen, P.E.

I have a few questions from your responses. Can you please review and respond. 1. We will adjust the west side of the wall accordingly. 2. We will get info from the manufacturer regarding any spacing required for proximity of fencing and submit. 3. We will adjust the notes on the plans accordingly to state the 2' clearance from top of old wall to finished grade. 4. With the change in height of the wall we are s saying in the Allen Block wall manufacturer but we will be able to change the specific product. We will submit all product info with our final submittal. 5. We will submit with a stamp. 6. Can you please clarify this last item. Are you looking to be sure that the wall is installed in the proper location per the new site plans? Jut want to be sure I am getting proper info. Yes, fees have been paid. I am confused as to the comment regarding the engineer of record. CTL Thompson is a soils engineer and TJC is a civil engineer. They do different things. What exactly are you looking for in regards to "The Engineer -of - Record also needs to be clarified..." We will await comments from Forestry before we make any changes to the landscape plans. Any idea on timing of this? I assume that the HOA documents are being reviewed by the proper powers that be and there will be comments coming from them, correct? Again, thanks for your repossess and let me know any further info from my responses.

Project Location The project is located in the northwest quarter of Section 28, Township 3 South, Range 68 West of the 6th P.M. The site is generally located in the western portion of the City of Wheat Ridge, Colorado, west of the intersection of West 32nd Ave and Quail St. The approximate location of the site is shown in the Site Vicinity Map on Figure 1. Existing Site Conditions At the time of our field exploration, the majority of the site was vacant and undeveloped. A vacant, existing single family residential structure was observed on the southern portion of the site. Several small accessory structures had been previously demolished. A review of aerial photographs and observations of site surface conditions indicate little to no development or activity has occurred at the site. At the time of this investigation, no overlot grading had not been completed. Topography of the site generally slopes down gradually toward the north. Vegetation generally consisted of sparse to moderate stands of grasses and weeds; several deciduous trees are located on the southern portion of the site in the area of the existing single family residential structure. Project Description Based on conversations with the client, the proposed project is to consist of the development of an approximately 5 acre parcel of vacant, mostly undeveloped property for residential development. It is our understanding the project will consist of the design and construction of seven single family residences. The homes may be constructed with or without basements. Scope of Work RMG was retained to assess the soil conditions and develop preliminary geotechnical engineering recommendations to support the residential land development for the proposed project. The scope of our services generally included the following. • Review of readily available aerial photographs and published geologic literature, including maps and reports pertaining to the project site and vicinity. • Notifying Utility Notification Center of Colorado (UNCC) of the soil sampling prior to drilling. • Drilling, logging, and sampling four exploratory borings within the project site to depths between approximately 20 and 30 feet below ground surface (bgs). heot Rgd�e o1'0; J RMG — Rocky Mountain Group 3 RMG Job No. 15 7169 • Performance of laboratory tests on selected samples obtained from the borings to evaluate engineering properties including in-situ moisture content and dry density, Atterberg limits, No. 200 sieve, swell/consolidation potential, and water soluble sulfates. • Preparation of this report presenting our findings, conclusions, and recommendations regarding the design and construction of the project. This report presents preliminary geotechnical engineering recommendations for the remediation of subsurface conditions and for design of foundations. This report does not constitute final construction recommendations. A site specific subsurface soil investigation should be performed for actual proposed structures prior to construction. FIELD INVESTIGATION AND LABORATORY TESTING The information included in this report has been compiled from field reconnaissance, maps of the site, exploratory soil borings and soil laboratory testing. Subsurface Investigation The subsurface conditions on the site were investigated by drilling four exploratory test borings. The approximate locations of the test borings are presented in the "Test Boring Location Plan on Figure 1. The test borings were advanced with a power -driven, continuous -flight auger drill rig to depths of about 20 to 30 feet below the existing ground surface (bgs). Samples were obtained in general accordance with ASTM D-1586 utilizing a 2 -inch OD split -barrel sampler or in general accordance with ASTM D-3550 utilizing a 2% -inch OD modified California sampler. An Explanation of Test Boring Logs is presented in Figure 2. The Test Boring Logs are presented in Figures 3 and 4. Laboratory Testing The moisture content for the recovered samples was obtained in the laboratory. Grain -size analysis, Atterberg Limits, and swell/consolidation tests were performed on selected samples for purposes of classification and to develop pertinent engineering properties. A Summary of Laboratory Test Results is presented in Figure 5. Soil Classification Test Results are presented in Figures 6. Swell/Consolidation Test Results are presented in Figures 7 through 9. GEOLOGY AND SUBSURFACE CONDITIONS Geologic Setting 'The project site is located approximately 6 miles east of the Rocky Mountains, within the Colorado Piedmont section of the Great Plains Physiographic Province. The City of Wheat Ridge is located within a large north -south trending structural basin called the Denver Basin RMG— Rock.v Mountain Group 4 RMGJob No. 1-57169 which consists of an asymmetric syncline of Paleozoic, Mesozoic, and Cenozoic sedimentary rock layers. The Denver Basin formed during the Laramide Orogeny that uplifted the Rocky Mountains during the late Cretaceous and early 'Tertiary (Trimble, 1980). The surficial geology of the site is mapped by Trimble and Machette (1979) as Holocene to late .Pleistocene -age Piney Creek Alluvium and Colluvium deposits. 'The underlying formational bedrock unit is snapped as the Denver Formation which consists of claystone, siltstone, sandstone, and conglomerate. Claystone and siltstone contain partially altered montmorillonitic clay. These clays expand when wet. Volumetric change of expansive soil may cause excessive cracking and heaving of structures with shallow foundations, concrete slabs -on -grade, or pavements supported on these materials. A review of a Colorado Geological Survey map delineating areas based on their relative potential for swelling in the Denver area by Hart (1973-4) indicates soil and bedrock materials in the project vicinity have high swell potential. Construction on soils known to be potentially expansive will have a significant impact to the project. Faulting and Seismicity Historically, several minor earthquakes have been recorded around the Denver metropolitan area. Based on our field observations and our review of readily available published geological maps and literature there are no known active faults underlying or adjacent to the subject site. The closest Quaternary -age fault is the Golden Fault, which lies approximately 6 miles west of the site. The fault has not shown recent displacement, as Pleistocene deposits overlie the fault. Therefore, the probability of damage at the site from seismically induced ground surface rupture is considered to be low. Based on the findings of our subsurface exploration program and the International Building Code developed by the International Code Council (ICC, 2012), a site specific Seismic Site Class D is appropriate for the project site. Soil and Bedrock Profile The subsurface materials encountered in the test borings were classified using the Unified Soils Classification System (USCS). No significant soils containing organics (topsoil) or non - engineered fills were encountered or observed at the site surface. Native soils were encountered at the surface in each of our borings and extended to depths ranging between approximately 19 feet below the existing ground surface (bgs) to the termination depth of the bore holes at 20 to 30 feet bgs. Native soils generally consisted of brown to dark brown, medium stiff to hard, sandy lean clay and fat clay. Silty sand was also encountered in test boring B-3 at a depth of 28 feet. Claystone bedrock was encountered in test boring B-1 starting at a depth of 19 feet and extending to the termination dept f the test boring. The claystone bedrock was light olive brown and bluish gray and /56T in ha> ess from firm to hard. Y 01 V'Vhoat Ridge „a:.,n Qi�I150r1 RMG — Rockv MOUntain Group 5 RMG Joh No. 157169 Additional descriptions and the interpreted distribution (approximate depths) of the subsurface materials are presented on the Test Boring Logs. The classifications shown on the logs are based upon the engineer's classification of the samples at the depths indicated. Stratification lines shown on the logs represent the approximate boundaries between material types and the actual transitions may be gradual and vary with location. Groundwater Ground water was not encountered in borings B-1 and B-2, but was encountered at a depth of 8 feet in boring B-3 and 9 feet in boring B-4 at the time of drilling. When checked on April 20, 2017, groundwater was observed in the test borings B-2, B-3, and B-4 at depths of ranging from 6 to 8 feet bgs, test boring B-1 had collapsed and groundwater was not observed. Fluctuations in groundwater and subsurface moisture conditions may occur due to variations in rainfall and other factors not readily apparent at this time. Development of the property and adjacent properties may also affect groundwater levels. Ground water will likely affect site development on this site. CONCLUSIONS The following discussion is based on the subsurface conditions encountered in the test borings and on the project characteristics previously described. The results of this investigation indicate that the site is suitable for the proposed project, however the site contains swelling clay soils and high ground water levels which will complicate earthwork operations and depending on final site grades the high groundwater may preclude the construction of basements. Soft and/or saturated conditions may be present once earthwork begins. Rutting, pumping and other complications should be expected. Dewatering, stabilization as well as other measures may be necessary to during construction. Prelirninary recommendations based oil the field investigation and laboratory testing, are presented below. It must be understood that these recommendations should be verified after the excavation on each individual lot is completed. SITE DEVELOPMENT AND EARTHWORK The following sections present our preliminary recommendations for site development and earthwork. Demolition This project will include demolition of an existing residence. Demolition should include complete removal of the structure and all associated concrete elements including any basement walls and slabs. Remnants from demolition activities should be removed from the site. Holes or voids resulting from removal of buried obstructions that extend below finish grade should be backfilled with compacted structural fill. The structural fill should be observed and tested RMG— Rockv Mountain Group b RMG Job No. 157169 during placement as indicated under the Structural Fill section of this report, to ensure proper compaction. Site Preparation Prior to construction, the ground surface in proposed structure and improvement areas should be stripped of existing vegetation, debris, topsoil, undocumented fill, soft, loose, or disturbed native soils, and other deleterious material. Materials generated during clearing operations should be removed from the project site for disposal. Soft, loose, or yielding subgrade should be removed to a depth that exposes firm subgrade and replaced with structural fill and/or stabilized. Excavations The on-site surface and near surface soils may generally be excavated with heavy-duty earthmoving or excavation equipment in good operating condition. We do not anticipate excavations will extend into the Denver Formation bedrock. Excavators and backhoes with buckets having large claws to loosen the soil should be avoided when excavating the bottom 12 inches as such equipment may disturb the excavation bases. Trim the bottom of the excavation to the required lines and grades to leave a solid base to receive other work. Excavating below the groundwater (or perched water) table may require dewatering and additional consideration. Excavations below the groundwater can result in filling the bottom of the excavation with loose, flowing soils. Such material will subsequently consolidate under the load of the footings and result in excessive settlements of structures bearing on it. The use of light -weight or tracked equipment is highly recommended for conducting the site excavations and grading. In addition, construction dewatering may also be needed. During wet weather, earthen berms, swales, or other methods should be used where necessary to route water away from excavations. Water that accumulates in excavations should be promptly pumped out or otherwise removed and the area allowed to dry before resuming construction. High ground water at this site will further complicate the excavation process. Dewatering and stabilization may be required. Overexcavation and Replacement The clay soils found on this site are not suitable for direct bearing of shallow foundations or floor slabs in its present condition. At the east end of the site we preliminarily recommend the overexcavation of the onsite soils beneath foundations and floor slabs, moisture conditioning, and replacement as structural fill to a depth which results in 5 feet of structural fill below foundation components and floor slabs. The zone of overexcavation shall extend beyond the building perimeter a distance equal to the depth of structural fill. Structural till d ,be observed and tested during placement as indicated in the following section, t;'(epths ure prope� compaction. In Borings B-2 through B-4 we encountered groundwater at ranging between approximately 6 to 8 feet below the existing ground surface. The elevated moisture contents associated with shallow groundwater conditions generally impede t -potential for RMG — Rocky Mountain GrouP 7 RMG ,lob No. 157169 significant swell. Therefore, we preliminarily recommend overexcavations terminate 3 feet above the static groundwater table. Structural Fill Structural fill should consist of granular import material. Import material should be sampled at the borrow source and approved by this office prior to importation to the project site. The till material shall be moisture conditioned and replaced as follows: • Imported fill should be free of organic material, and other deleterious materials. Imported fill should preferably consist of relatively impervious material with 20 to 50 percent passing the No. 200 sieve and should exhibit a low swell potential (approximately 2 percent or less when wetted against a surcharge pressure of 200 psf) and shall not contain rocks or cobbles greater than 4 inches in diameter. • Structural fill materials should be placed in maximum 8" compacted lifts and moisture conditioned to within 2 percent of optimum moisture content. These materials should be compacted to a minimum of 95 percent of the maximum dry density as determined by the Standard Proctor test (ASTM D-698). Material not meeting the above requirements shall be reprocessed. • Moisture -conditioned structural fill placed on slopes should be benched into the slope. Maximum bench heights should not exceed 4 feet, and bench widths should be wide enough to accommodate compaction equipment. • Structural fill materials shall not be placed, moisture conditioned, or rolled while they are frozen. Earthwork operations should be observed and compaction of engineered till and backfill materials should be tested by the project's geotechnical consultant. Early testing is recommended to demonstrate that placement and compaction methods are achieving the required compaction for the entire depth of fill. Without a strict quality assurance program, the fill may not be of sufficient quality to achieved required performance. Foundation Wall Backfill Foundation wall backfill may consist of onsite material and should be placed in loose lifts not exceeding 8 to 12 inches, moisture conditioned to facilitate compaction (usually within 2 percent of the optimum moisture content) and compacted to 90 percent of the maximum dry density as determined by the standard Proctor test, ASTM D-698 on exterior sides of walls in landscaped areas. In areas where backfill supports pavement and concrete flatwork, the materials should be moisture conditioned to I percent to 4 percent above optimum moisture content compacted to 95 percent of the maximum dry density. Backfill placed against slopes should be benched into the slope. Maximum bench heights should not exceed 4 feet. and bench widths should be wide enough to accommodate compaction equipment. The backfill should not be placed on frozen subgrade or allowed to RM(.J— Rocky Mountain Group 8 RNIG Job No. 15716,) freeze during moisture conditioning and placement. Backfill should be compacted by mechanical means, and foundation walls should be braced during backfilling and compaction. Utilitv Construction The contractor should provide adequate mechanical compaction in the utility trench backfills. The contractor should take particular care in the lower portions of excavations and around manholes, valve risers and other vertical pipeline elements where settlements are commonly observed. Our experience indicates that significant settlement of backfill can occur in utility trenches, particularly when trenches are deep, when backfill materials are placed in thick lifts with insufficient compaction, and when water can access and infiltrate the trench backfill materials. Consideration should be given to use of "flowable fill," (e.g. a controlled low strength mix (CLSM), or a similar material) in lieu of compacted soil backfill in areas with low tolerances for surface settlements, in deep excavations, and areas with difficult access. Soils in utility excavations may encounter "Type A" or "Type B" soil according to OSHA regulations. Trench backfill should be compacted to City and/or County specifications and it is recommended that a representative of RMG provide full-time observation and compaction testing. Sandy pipe bedding materials can function as conduits for re -distribution of natural and applied waters in the subsurface. Development of site grading plans should consider the subsurface transfer of water in utility trenches and the pipe bedding in areas where the utility service trenches enter structures. Cut-off walls in utility trenches or other water -stopping measures may be implemented to reduce the rates and volumes of water transmitted along utility alignments toward structures, where wetting of the underlying soils increases the potential for soil movements, material degradation, or structural distress. PRELIMINARY FOUNDATION OPTIONS The foundation options below are based on the preliminary subsurface soil findings documented in this report. The recommendations for each individual lot will depend on the subsurface investigation for that specific lot to be conducted at a later time. RMG should be retained for each individual site for further soil exploration and will then provide specific foundation recommendations for each individual lot. Anticipated Foundation Systems Shallow Foundation Svstems We anticipate spread footing foundation systems may be utilized at this site, however the presence of expansive clay soil will necessitate overexcavation and replacement with structural fill on portions of the site. The actual overexcavation recommendations will be determined during the site specific subsurface soil investigation. A maximum allowable bearing pressure of approximately 1,500 to 2,500 psf may be used for pla mg pure es. Foundation components must be below all organic material and undoc. mented fill a should extend 36 inches or more below the lowest exterior finished grade . for fro. evilry;n �P RMG — Rocky Mountain Group 9 RMG ,lob No. 157169 protection. The foundation design should be prepared by a qualified Colorado Registered Professional Engineer using the recommendations presented in this report. This foundation system should be designed to span a minimum of 10 feet under the design loads. Drilled Pier Foundation Systems Drilled piers bearing in Denver Formation bedrock may be utilized at this site. However, it should be noted that bedrock was only encountered in Boring B-1 at a depth of approximately 19 feet bgs. Bedrock was not encountered in Borings B-2 through B-4 to the maximum depth explored. Therefore, piers may need to be designed to carry the majority of the loads in friction or may need to be extended beyond 30 feet in depth. If piers are the desired option a lot specific soils report with borings drilled to a minimum of 35 feet will provide final design criteria. Additional deeper drilling may be required to accurately map the depth to bedrock across the site. INTERIOR FLOOR SYSTEMS The following sections present our recommendations for floor systems and partition walls. Interior Floor Slabs Vertical slab movement of one to three inches is considered possible for slabs bearing on moisture conditioned structural till. In some cases, vertical movement may exceed this range. If movement and associated damage to floors and finishes cannot be tolerated, a structural floor system should be used. Floor slabs should be separated from structural components to allow for vertical movement. Control and construction joints should be placed in accordance with the latest guidelines and standards published by the American Concrete Institute (ACI) and applicable local Building Code requirements. Recommendations for exterior concrete slabs, such as patios, driveways, and sidewalks, are not included in this report. Structural Floor Systems If movement of a floor slab cannot be tolerated, a structural floor system (supported by the foundation independently of the subgrade soils) is recommended for the interior floor system of the proposed structures. This may include conventional floor framing or a structural concrete slab adequately voided from the soil below. Suspended slab systems include the Tella Firma concept, which uses a post -tensioned structural concrete slab poured on the ground and raised to create the required floor space. Garage floor slabs supported on moisture condition structural till may experience vertical movement of one to three inches, or more. If a non -concrete system is used, environmental health hazards associated with mold growth in crawlspaces must be reduced by utilizing "clean" construction methods. The floor should be RMG - Rocky Mountain Group 10 RMG Joh No. 157169 properly sealed and vented. A ventilation system activated by temperature and humidity levels may be required in the crawlspace. The entire floor system and ventilation system should be designed by a qualified professional. Interior Partitions Interior non-bearing partitions and attached furnishings (e.g., cabinets, shower stalls, etc.) on concrete slabs should be constructed with a void so that they do not transmit floor slab movement to the roof or overlying floor. A void of at least 2 inches is recommended beneath non-bearing partitions. The void may require reconstruction over the life of the structure to re- establish the void due to vertical slab movement. Interior non-bearing partitions and other attached finishes do not require isolation from floor slabs that comprise a stiffened slab -on -grade foundation system. LATERAL EARTH PRESSURES For on-site moisture conditioned backfill materials, the estimated range will likely be equivalent fluid densities of 60 pcf for Active conditions and 80 pcf for At -Rest conditions. The lateral pressure applies to level, drained backfill conditions. These values assume the backfill will not become saturated during the life of the structure, therefore positive surface drainage must be maintained. It is also assumed that compaction within approximately 5 feet of the walls will be accomplished with relatively light compaction equipment. Equivalent Fluid Pressures for sloping/undrained conditions should be determined on an individual basis. SURFACE DRAINAGE The ground surface should be sloped from the building with a minimum gradient of 10 percent for the first 10 feet. This is equivalent to 12 inches offal] across this 10 -foot zone. If a l 0 -foot zone is not possible on the upslope side of the structure, then a well-defined swale should be created a minimum 5 feet from the foundation and sloped parallel with the wall with a minimum slope of 2 percent to intercept the surface water and transport it around and away from the structure. Roof drains should extend across backfill zones and landscaped areas to a region that is graded to direct flow away from the structure. Homeowners should maintain the surface grading and drainage recommended in this report to help prevent water from being directed toward and/or ponding near the foundations. Landscaping should be selected to reduce irrigation requirements. Plants used close to foundation walls should be limited to those with low moisture requirements and irrigated grass should not be located within 5 feet of the foundation. To help control weed growth, geotextiles should be used below landscaped areas adjacent to foundations. Impervious plastic membranes are not recommended. Irrigation devices should not be placed within 5 feet of the foundation. I i anon should be limited to the amount sufficient to maintain vegetation. Application of mo water vNN increase the likelihood of slab and foundation movements. a eco RMC,— Rocky Mountain Group I 1 RMG Job No. 157169 The recommendations listed in this report are intended to address normal surface drainage conditions, assuming the presence of groundcover (established vegetation, paved surfaces, and/or structures) throughout the regions upslope from this structure. However, groundcover may not be present due to a variety of factors (ongoing construction/development, wildfires, etc.). During periods when groundcover is not present in the "upslope" regions, higher than normal surface drainage conditions may occur, resulting in perched water tables, excess runoff, flash floods, etc. In these cases, the surface drainage recommendations presented herein (even if' properly maintained) may not mitigate all groundwater problems or moisture intrusion into the structure. We recommend that the site plan be prepared with consideration of increased runoff during periods when groundcover is not present on the upslope areas. CONCRETE Type I/II cement is recommended for concrete in contact with the subsurface materials. Calcium chloride should be used with caution for soils with high sulfate contents. The concrete should not be placed on frozen ground. If placed during periods of cold temperatures, the concrete should be kept from freezing. This may require covering the concrete with insulated blankets and heating. Concrete work should be completed in accordance with the latest applicable guidelines and standards published by ACI.
