Job No. 165766 July 1, 2019 Journey Homes, LLC 7251 W. 20th St., L-200 Greeley, CO 80634 Attn: Larry Buckendorf Attn: Joe Schumacher Re: Addendum to the Soils Report – Lateral Earth Pressures Severance Shores Sec 34, T 7 N, R67W of the 6th P.M. Severance, Colorado Larry, As requested, RMG – Rocky Mountain Group performed a subsurface soils investigation (SSI) for all lots located at the above referenced site and provided our findings and recommendations in a report last dated March 20, 2019. The recommendations for lateral earth pressures included in the original soils report were listed for “Active” and “At-Rest” conditions. Upon submitting the soils report, the client has requested that RMG provide this addendum to clarify the lateral earth pressures and the applicable situations to use “Active” versus “At-Rest”. The International Building Code (IBC 2015) 1610.1 says,
“Foundation walls and other walls in which horizontal movement is restricted at top shall be designed for “At-Rest” pressure. Exception: Foundation walls extending not more than 8 feet below grade and laterally supported at the top by flexible diaphragms shall be permitted to be designed for active pressure.”
Therefore, the “Active” earth pressure recommendation of 50 pcf may be used for foundation walls that do not extend farther than 8 feet below grade and that are supported at the top by flexible diaphragms. Additionally, walls in which the top is not restricted at top at the time of backfill may also be designed using the “Active” earth pressure to allow for slight movement in the foundation walls due to backfilling practices.
Sec 34, T 7 N, R67W of the 6th P.M. Severance, Colorado
RMG – Rocky Mountain Group 2 RMG Job No. 165766
For lots where the foundation walls will be horizontally restricted at top prior to backfill and/or the walls extend deeper than 8 feet below grade, the 70 pcf “At-Rest” pressure may be used for design purposes. Should you have questions, please feel free to contact our office. Cordially, RMG – Rocky Mountain Group Lauren Caruso, P.E. Geotechnical Project Engineer

Job No. 165766 May 3, 2019 Journey Homes, LLC 7251 W. 20th St., L-200 Greeley, CO 80634 Attn: Larry Buckendorf Attn: Joe Schumacher Re: Subsurface Soils Investigation Addendum #2 Severance Shores Sec 34, T 7 N, R67W of the 6th P.M. Severance, Colorado Larry: As requested, RMG – Rocky Mountain Group performed a subsurface soils investigation (SSI) for all lots located at the above referenced site and provided our findings and recommendations in a report last dated March 20, 2019. The soils investigation consisted of drilling approximately 136 bores, one test boring per every other lot. Samples were obtained from each boring at specific depths and select soil samples were tested for soil classification and swell potential. The site consisted of sandy clay fill, native sandy clay and siltstone bedrock. The swell test results indicated that the clay soils encountered at the site exhibited low to very high swell potential and the swelling soils were located sporadically across the subdivision. The highest concentration of swelling soils was encountered in the northern half of the subdivision with isolated pockets of high swelling soils identified in the southern portion. Groundwater was encountered within three feet (3’) of anticipated foundation depths in the south - southeastern test borings. The geotechnical considerations provided in the original SSI report were separated by lot location and anticipated soil treatment i.e. depth of overexcavation and appropriate replacement material and impact of groundwater. After reviewing the swell test results, field logs, cut/fill diagram, and evaluating the soils encountered in four excavations on-site, RMG amended the SSI report which reduced the required overexcavations and submitted an addendum last dated April 3, 2019. After the addendum was submitted, members from RMG and Journey Homes met to discuss the soil treatment recommendations at Severance Shores. It was discussed that the northern lots (lots located adjacent to and north of Kit Street) would be either be overexcavated to a depth of 4 feet and replaced with imported granular structural fill or to a depth of 14 feet below grade which is approximately 8 feet below basement grade and replaced with moisture conditioned on-site soils, as recommended in our first addendum. The on-site clay soils would be moisture conditioned to -1 to +3 percent above optimum moisture content and recompacted to 95% compaction as determined by the Standard Proctor Test (ASTM D698). It was also determined that RMG would investigate 25 additional lots in the southern portion of the subdivision and conduct a swell test from each of these borings to identify if the lots
Sec 34, T 7 N, R67W of the 6th P.M. Severance, Colorado
RMG – Rocky Mountain Group 2 RMG Job No. 165766
would require soil treatment prior to construction. The Swell Summary Plan is presented in Figure 1 and depicts which lots were included in this investigation. The Test Boring Logs for the additional test borings are presented in Figures 2 through 14. An Explanation of Test Boring Logs is presented in Figure 15. The moisture content for the additional samples was obtained in the laboratory. Swell/consolidation tests were performed on selected samples from each test boring. A Summary of Laboratory Test Results is presented in Figure 16. Swell/Consolidation results are presented in Figures 17 through 29. Our findings and recommendations are presented below. Northern Lots The swells in this area were highly variable ranging from 0.2% up to 6.7% with a 1000 psf initial load prior to adding water. Per our first addendum, we recommend an overexcavation and replacement with non-expansive, granular structural fill to a depth which results in at least 4 feet of compacted granular structural fill below foundation components and floor slabs. The structural fill should be observed and tested during placement as indicated under the Structural Fill section of the original SSI report, to ensure proper compaction. The zone of overexcavation and replacement should extend beyond the building perimeter a minimum of 4 feet for granular, non-expansive structural fill. An alternative stabilization method for the northern lots would be removal and replacement (overexcavation) with 8 feet of moisture-conditioned of on-site clay soils in general accordance with the Moisture-Conditioned Structural Fill section of the original SSI report. As such, the on-site soils should be moisture conditioned -1 to +3 percent of optimum moisture and recompacted to 95% compaction as determined by the Standard Proctor Test (ASTM D698). It must be understood that moisture conditioning expansive soils does not entirely remove swell potential. It is recommended that each lot be drilled following the completion of the soil reconditioning to verify swell potential and bearing capacity recommendations. If the builder choses to forego drilling each lot after the soils have been reconditioned, it is recommended that additional swell samples be collected during the Open Excavation Observation and tested prior to forming the footings. This additional testing may slow the construction process by a few days while the swell tests are completed; however, it will be imperative that the soils be tested prior to construction to verify swell potential has been reduced. Maintaining the moisture of the clay soils at or above optimum is critical to reduce swell potential in expansive soils. It must be understood that if an excavation is left open for an extended period of time and/or the soils lose moisture, the swell potential will increase. Southern Lots During the first investigation, these lots generally exhibited swells of less than 2%, however, moderate to high swells were encountered in this area, specifically Lots 20 and 91. During the second investigation the additional lots generally exhibited swells less than 2% with the exception of Lot 99 which swelled 3.7%. After reviewing the lab results from both investigations, we feel it acceptable to remove the overexcavation and replacement recommendation for the southern lots. This amendment is valid unless, during the Open Excavation Observation, dry and/or expansive soils are encountered. At that time, additional swell samples should be tested to determine if an overexcavation, meeting the requirements for these lots in the original SSI report, is necessary. This additional testing may slow the construction
Sec 34, T 7 N, R67W of the 6th P.M. Severance, Colorado
RMG – Rocky Mountain Group 3 RMG Job No. 165766
process by a few days while the swell tests are completed; however, it will be imperative that the soils be tested prior to construction to identify swell potential and provide the appropriate recommendation. Please note, due to the identified moderate to high swell potential, Lots 20, 91 and 99 will require the original overexcavation and replacement recommendations from the original SSI report. Lots with Groundwater or Soft/loose Soils Seven of the additional lots were drilled in the area of shallow groundwater. Groundwater was encountered within 2 feet of anticipated foundation depths in Lots 122, 126 and 142. Recommendations for lots where saturated soils or groundwater is encountered near foundation elevations remain valid from the original SSI report and are not being amended in this addendum. Similarly, the recommendations for lots where soft/loose soils are encountered during the Open Excavation Observation remain valid from the original SSI report. Should you have questions, please feel free to contact our office. Cordially, RMG – Rocky Mountain Group Lauren Caruso, P.E. Geotechnical Project Engineer

Re: Subsurface Soils Investigation Addendum #1 Severance Shores Sec 34, T 7 N, R67W of the 6th P.M. Severance, Colorado
Larry:
As requested, RMG – Rocky Mountain Group performed a subsurface soils investigation (SSI) for the above referenced site and provided our findings and recommendations in a report last dated March 20, 2019. The soils investigation consisted of drilling approximately 136 bores, one test boring per every other lot to maximum depths of 25 feet below existing grade. Samples were obtained from each boring at specific depths and select soil samples were tested for soil classification and swell potential. The site consisted of sandy clay fill, native sandy clay and siltstone bedrock. The swell test results indicated that the clay soils encountered at the site exhibited low to very high swell potential. The highest concentration of swelling soils was encountered in the northern half of the subdivision with isolated pockets of high swelling soils identified in the southern portion. Groundwater was encountered within three feet (3’) of anticipated foundation depths in the south - southeastern test borings.
The geotechnical considerations provided in the original SSI report were separated by lot location and anticipated soil treatment i.e. depth of overexcavation and appropriate replacement material and impact of groundwater.
After reviewing the swell test results, field logs, cut/fill diagram of the site and visiting the site to evaluate four excavations, it was determined the original overexcavations and replacement recommendation can be amended as follows:
Northern Lots
The swells in this area were highly variable ranging from 0.2% up to 6.7% with a 1000 psf initial load prior to adding water. We recommend each lot be drilled and evaluated to determine if soil modifications will be necessary or to what extent the soils will require to be modified to meet a spread footing foundation system.
Addedum #1 – Subsurface Soils Investigation Sec 34, T 7 N, R67W of the 6th P.M.
Severance, Colorado
RMG – Rocky Mountain Group 2 RMG Job No. 165766
In lieu of drilling each lot to determine the extent of the swelling soil, the following recommendations are made:
We recommend removal (overexcavation) and replacement with non-expansive, granular structural fill to a depth which results in at least 4 feet of compacted granular structural fill below foundation components and floor slabs. The structural fill should be observed and tested during placement as indicated under the Structural Fill section of the original SSI report, to ensure proper compaction. The zone of overexcavation and replacement should extend beyond the building perimeter a minimum of 4 feet for granular, non-expansive structural fill.
An alternative stabilization method for the northern lots would be removal and replacement (overexcavation) with 8 feet of moisture-conditioned of on-site clay soils in accordance with the Moisture-Conditioned Structural Fill section of the original SSI report. The zone of overexcavation and replacement should extend beyond the building perimeter a minimum of 4 feet for moisture-conditioned onsite soils, including beyond the perimeter of counterforts and "T" wall footings.
Southern Lots
These lots generally exhibited swells of less than 2%; however, moderate to high swells were encountered in this area, specifically Lots 20 and 91. Due to the sporadic locations of the swelling soils, it was originally recommended to remove the soils or moisture condition the soils to specific depths to reduce the potential for expansive soils that were previously untested from damaging foundations and slabs.
However, after reviewing the lab data, visiting the site and reviewing the cut/fill diagram, the amended recommendation is to remove the overexcavation and replacement recommendation for the lots located in the southern area. This amendment is valid unless, during the Open Excavation Observation, dry and/or expansive soils are encountered. At that time, additional swell samples should be tested to determine if an overexcavation, meeting the requirements for these lots in the original SSI report, is necessary. This additional testing may slow the construction process by a few days while the swell tests are completed; however, it will be imperative that the soils be tested prior to construction to identify swell potential and provide the appropriate recommendation.
Please note, due to the previously identified swell potential, Lots 20 and 91 will require the original overexcavation and replacement recommendations from the original SSI report. Additionally, surrounding lots will be required to be tested for swell potential and therefore may also require soil treatment prior to construction.
Lots with Groundwater or Soft/loose Soils
Recommendations for lots where groundwater was encountered near foundation elevations remain valid from the original SSI report and are not included in this addendum. Similarly, the recommendations for lots where soft/loose soils are encountered during the Open Excavation Observation remain valid from the original SSI report.
Finally, during the review of the logs, it became apparent that the depth to groundwater was entered incorrectly on several bore logs. Please find attached the corrected logs reflecting the appropriate depth to groundwater.

PROJECT DESCRIPTION AND SCOPE
Project Location
The project lies in part of the northeast quarter of Section 34, Township 7 North, Range 67 West of the 6th Principal Meridian. The site is generally located to the west of the Town of Severance in Weld County, Colorado. The site is located north of County Road 74, west of County Road 21 and east of the Windsor Reservoir. The approximate location of the site is shown in the Site Vicinity Map on Figure 1.
Project Description
The project is to consist of the development of a parcel of vacant, semi-developed property for residential use. It is our understanding that this development will be occupied by single family residences with no multifamily units planned at this time. RMG was retained to evaluate the subsurface conditions for the 267 lots within the proposed Severance Shores Subdivision.
Scope of Work
RMG was retained to assess the soil conditions and develop geotechnical engineering recommendations to support the residential land development for the proposed project. Our scope of services consisted of a field investigation, laboratory testing, engineering analysis, and report preparation. This report presents geotechnical engineering recommendations for the design of foundations for the single family residences located on the lots listed above. The recommendations in this report are also contingent upon completion of an Open Excavation Observation by RMG, prior to construction of the foundations in order to verify subsurface conditions for the specific excavated site. The following is excluded from the scope of this report including but not limited to geologic, natural and environmental hazards such as landslides, unstable slopes, seismicity, snow avalanches, water flooding, corrosive soils, erosion, radon, wild fire protection, hazardous waste and natural resources.
Existing Site Conditions
Prior to our investigation, clayey fill material was placed across a significant portion of the site predominately in the northern portion and western portion of the proposed subdivision. RMG was not provided with information regarding the compaction results and moisture conditioning of the fill material. At the time of our field exploration the subdivision was semi-vacant property with the fill placed. Overlot grading had been completed prior to our investigation. Water and sewer connections were being installed during our investigation in the northern portion of the site. Sewer connections had been installed in the southern portion of the subdivision during out investigation but water had not been. Curb and gutter had not been installed and the roads had not been paved. Topography of the site generally sloped gently down from the northeast to the southwest portion of the site. Vegetation was not present at the site due to the overlot grading. The surrounding areas consisted of residential properties to the east and the Windsor Reservoir to the west of the subdivision.
RMG – Rocky Mountain Group 4 RMG Job No. 165766
FIELD INVESTIGATION AND LABORATORY TESTING
The information included in this report has been compiled from field reconnaissance, exploratory soil borings and soil laboratory testing. Monitoring programs, which typically include instrumentation and/or observations for surface water flows, slope stability, subsidence, and similar conditions, are not known to exist and were not considered applicable for the scope of this report.
Subsurface Investigation
The subsurface conditions on the site were investigated by drilling 136 exploratory test borings, approximately one bore advanced per every other lot in this investigation. The bores were placed near the center of each lot. The approximate locations of the test borings are presented in the Boring Location Plan on Figure 2a.
The test borings were advanced with a truck-mounted, continuous-flight auger drill rig to depths of about 20 feet below the existing ground surface (bgs). Soil samples were obtained from the test borings in general accordance with ASTM D-3550 utilizing a 2½-inch OD modified California sampler. The approximate depth of groundwater was investigated in each of the test borings at the time of drilling. The static groundwater levels were measured following the completion of drilling. The Test Boring Logs are presented in Figures 3 through 70. An Explanation of Test Boring Logs is presented in Figure 71.
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 72. Soil Classification and Atterberg Test Results are presented in Figures 73 through 79. Swell/Consolidation Test Results are presented in Figures 80 through 100.
SUBSURFACE CONDITIONS
Soil and Bedrock Profile
The subsurface materials encountered in the test borings were classified using the Unified Soils Classification System (USCS). The subsurface materials encountered in the test borings generally consisted of an upper fill material comprised of medium stiff to very stiff sandy silty clay. Underlying the fill material, native stiff sandy clay and medium dense clayey to silty sand was encountered predominately in the northern and western portion of the site. Underlying the upper soils in the south and southeastern portion of the subdivision, siltstone bedrock was encountered beneath the clay fill material. The siltstone bedrock was encountered in 47 of the test borings at depths ranging from approximately 7 feet to 18 feet below existing grade. The siltstone was encountered near anticipated foundation depths in the southeastern lots of the subdivision. 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
RMG – Rocky Mountain Group 5 RMG Job No. 165766
on the logs represent the approximate boundaries between material types and the actual transitions may be gradual and vary with location. Groundwater
Groundwater was encountered in 35 of the test bores at the time of drilling at depths ranging from 8 feet bgs to 18.5 feet bgs. When checked following the completion of drilling, static groundwater was observed in each of the 35 test bores at depths ranging from 6 to 17.5 feet bgs. Groundwater was encountered at depths of 10 feet or less below existing grade in 20 of the test bores. Of those 20 test borings, groundwater was encountered within two feet of anticipated foundation elevations in 11 of the lots. Groundwater was encountered in the south and southeastern portions of the subdivision. The Recommendations Summary Plan, Figure 2b depicts the areas where groundwater was encountered within 10 feet of existing grade. 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.
CONCLUSIONS
The following discussion is based on the subsurface conditions encountered in the test borings and on the project characteristics previously described. If conditions are different from those described in this report or the project characteristics change, RMG should be retained to review our recommendations and adjust them, if necessary. The results of this investigation indicate that the site is suitable for the proposed project provided the recommendations presented herein are implemented. As previously discussed the site is underlain primarily by an upper fill material comprised of medium stiff to very stiff sandy silty clay, native soils consisting of medium dense clayey to silty sand and stiff sandy clay and weathered to very hard siltstone bedrock. The clay fill samples tested generally exhibited no consolidation and up to 6.7% swell. The majority of the fill samples tested exhibited swells greater than 1.5%. Samples from lots located north of Kit Street generally exhibited the highest swell potential although swell results from samples tested on Lot 20, Lot 91and Lot 151 also exhibited moderate to high swell potential. The siltstone bedrock samples tested generally exhibited less than 0.3% swell and less than 0.5% consolidation. Swell/consolidation tests for this investigation were performed by wetting the samples against 1,000 psf surcharge pressures. Geotechnical recommendations based on 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
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. In areas to receive structural fill,
RMG – Rocky Mountain Group 6 RMG Job No. 165766
the exposed subgrade should be scarified, moisture conditioned, and compacted per the recommendations set forth in this report. Excavations
The on-site surface and near surface soils may generally be excavated with heavy-duty earthmoving or excavation equipment in good operating condition. In the areas where auger refusal was encountered due to the sandstone bedrock, heavier equipment may be required to break through the sandstone. 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. Geotechnical Considerations
Overexcavations: The non-expansive siltstone bedrock encountered is suitable for the direct bearing of shallow foundations. The silty to sandy clay fill throughout the site possesses moderate to high swell potential and is not suitable for direct support of shallow foundations for any lot within the subdivision. The lots located along Kit Street and to the north of Kit Street exhibited the highest swell potential. Kit Street divides the subdivision in half, therefore the recommendations for overexcavations for the lots in the northern half of the subdivision differ from the overexcavation recommendations for the southern half. Northern Lots: Due to the high expansion potential of the clay fill placed predominately across the northern lots, the existing fill material will be required to be removed and replaced with granular structural fill. These lots will require removal (overexcavation) and replacement with non-expansive, granular structural fill to a depth which results in at least 6 feet of compacted granular structural fill below foundation components and floor slabs. The structural fill should be observed and tested during placement as indicated under the Structural Fill section of this report, to ensure proper compaction. The zone of overexcavation and replacement should extend beyond the building perimeter a minimum of 4 feet for granular, non-expansive structural fill. For lots where native soils are encountered within 6 feet of the bottom of the foundations, it is permissible to remove the expansive fill to the native soils and backfill with granular structural fill. Southern Lots: Due to the low to moderate expansion potential of the clay fill placed the southern lots, the existing fill material will be required to be removed and replaced with granular structural fill. These lots will require removal (overexcavation) and replacement with non-expansive, granular structural fill to a depth which results in at least 3 feet of compacted granular structural fill below foundation components and floor slabs. The structural fill should be observed and tested during placement as indicated under the Structural Fill section of this report, to ensure proper compaction. The zone of
RMG – Rocky Mountain Group 7 RMG Job No. 165766
overexcavation and replacement should extend beyond the building perimeter a minimum of 3 feet for granular, non-expansive structural fill An alternative stabilization method for the southern lots would be removal and replacement (overexcavation) with 5 feet of moisture-conditioned of on-site clay soils in accordance with the Moisture-Conditioned Structural Fill section of this report. The zone of overexcavation and replacement should extend beyond the building perimeter a minimum of 4 feet for moisture-conditioned onsite soils, including beyond the perimeter of counterforts and "T" wall footings. Groundwater: Groundwater was found near the vicinity of anticipated foundation depths in 20 test bores located in the south and southeastern portion of the subdivision. A minimum 3 foot separation is recommended between the bottom of the foundation components and the estimated seasonal high water table levels. A 3 foot layer of ¾” to 1.5” diameter washed rock or ¾” to 3.0” diameter crushed concrete with both of these options containing less than 5% passing the #200 sieve is recommended directly beneath the footings and slabs if the groundwater is identified to be within 3 feet of the bottom of the foundation or if saturated soft soils are encountered at foundation bearing depths during the Open Hole Observation. Soft/Loose Soils: Soft/loose soils were encountered at anticipated foundation depths throughout the subdivision. Soft/loose soils under foundation components should have the top 6 inches scarified, moisture-conditioned to within -1% to +3% of optimum moisture content, and compacted to a minimum of 95% maximum dry density as determined by the Standard Proctor (ASTM-698) and in accordance with the Moisture-Conditioned Structural Fill section of this report. Isolated pockets of loose soils may be encountered in the excavations, even on lots where none are indicated on the test borings. If soft/loose soils are encountered, they may also require additional compaction and/or stabilization as previously mentioned to achieve the allowable bearing pressure indicated in this report. All Lots: The Recommendations Summary Plan, Figure 2b, depicts the anticipated soil treatment recommendations for all lots in the subdivision. These recommendations are dependent on RMG conducting the Open Excavation Observations for each lot. During the Open Excavation Observation, the soils and bedrock in each lot will be evaluated for the relative compaction and swell potential of the soils within and beneath the excavation. Following the Open Excavation Observation, RMG will recommend the depth of overexcavation and replacement in the areas of expansive soils, depth of crushed concrete or washed rock in the presence of saturated soils or groundwater and possibly request additional swell testing be conducted prior to placing granular structural fill. Please note, the Recommendations Summary Plan is NOT considered final. Lots in the southern portion of the site may still require a minimum 6 foot overexcavation and replacement with granular structural fill if the soils are deemed to be similarly expansive as the soils in the northern portion during the Open Excavation Observation. Additionally, saturated soils or groundwater may be encountered in areas not shown on the Recommendations Summary Plan and these lots will require the appropriate soil treatment prior to construction.

Foundation Wall Backfill
Backfill should be placed in loose lifts not exceeding 8 to 12 inches with material no greater than 4 inches in diameter, 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 +/- 2 percent optimum moisture content compacted to 95 percent of the maximum dry density as determined by the Standard Proctor test, ASTM D-698. 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. Expansive bedrock should not be used as backfill materials. The backfill should not be placed on frozen subgrade or allowed to freeze during moisture conditioning and placement. Backfill should be compacted by mechanical means, and foundation walls should be braced during backfilling and compaction. Structural Fill
Areas to receive structural fill should have topsoil, organic material, or debris removed. The upper 6 inches of the exposed surface soils should be scarified and moisture conditioned to facilitate compaction (usually within 2 percent of the optimum moisture content) and compacted to a minimum of 95 percent of the maximum dry density as determined by the Standard Proctor test (ASTM D-698) prior to placing structural fill.
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 shall consist of granular, non-expansive material, and it 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 a minimum of 95 percent of the maximum dry density as determined by the Standard Proctor test, ASTM D-698. The materials should be compacted by mechanical means.
Materials used for structural fill should be approved by RMG prior to use. Structural fill should not be placed on frozen subgrade or allowed to freeze during moisture conditioning and placement.
To verify the condition of the compacted soils, density tests should be performed during placement. The first density tests should be conducted when 24 inches of fill have been placed. Moisture-Conditioned Structural Fill
Areas to receive moisture-conditioned structural fill should have topsoil, organic material, or debris removed. The upper 6 inches of the exposed surface soils should be scarified and moisture conditioned to -1 to +3 percent optimum moisture content and compacted to a minimum of 95 percent of the maximum dry density as determined by the Standard Proctor test (ASTM D-698) or to a minimum of 92 percent of the maximum dry density as determined by the Modified Proctor test (ASTM D-1557) prior to placing structural fill.
RMG – Rocky Mountain Group 9 RMG Job No. 165766
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.
Moisture conditioned structural fill shall consist of a moisture-conditioned, on-site cohesive fill material. The fill material shall be moisture conditioned and replaced as follows:
• Fill shall be free of deleterious material and shall not contain rocks or cobbles greater than 6
inches in diameter. • Claystone fill shall be thoroughly "pulverized" and shall not contain claystone chunks greater
than 1 1/2 inches in diameter. • When claystone is to be incorporated, the fill materials shall be processed in a stockpile
(processing these materials in the excavations will not be permitted). These stockpiled fill materials shall be moisture-conditioned to -1 to +3 percent optimum moisture content (as determined by the Standard Proctor test, ASTM D-698), with an average of not less than optimum moisture content. These materials, once moisture conditioned and thoroughly mixed, should rest in the stockpile a minimum of 24 hours to ensure proper distribution of the moisture through the material. After resting, the materials should be re-wet and re-mixed to replace the surficial moisture lost to evaporation during the resting period.
• Fill materials not containing claystone do not require processing in a stockpile, but shall be moisture-conditioned to -1 to +3 percent optimum moisture content (as determined by the Standard Proctor test, ASTM D-698), with an average of not less than optimum moisture content.
• The moisture-conditioned materials should be placed in maximum 6" compacted lifts. 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.
Materials used for moisture-conditioned structural fill should be approved by RMG prior to use. Moisture-conditioned structural fill should not be placed on frozen subgrade or allowed to freeze during moisture conditioning and placement.
To verify the condition of the compacted soils, density tests should be performed during placement. The first density tests should be conducted when 24 inches of fill have been placed.
FOUNDATION OPTIONS
Anticipated Foundation Systems
A spread footing foundation system may be utilized at this site bearing on the appropriate material as determined during the Open Hole Excavation. A maximum allowable bearing pressure of 2,000 psf with a minimum dead load of 500 psf may be used for design purposes. Foundation components must be below all organic material and should extend 30 inches or more below the lowest exterior finished grade for frost 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.
RMG – Rocky Mountain Group 10 RMG Job No. 165766
Open Excavation Observations
During construction, foundation excavations should be observed by RMG prior to placing structural fill, forms or concrete to verify the foundation bearing conditions for each structure.
INTERIOR FLOOR SYSTEMS
Interior Floor Slabs
Vertical slab movement of one to two inches is considered possible for slabs bearing on reconditioned soils of low to high swell potential. 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. 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 1-1/2 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.
LATERAL EARTH PRESSURES
Foundation walls should be designed to resist lateral earth pressures. For the cohesive on-site moisture conditioned backfill materials, we recommend an active equivalent fluid pressure of 50 pcf and an “at-rest” equivalent fluid pressure of 70 pcf be used for design purposes. 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 GRADING AND DRAINAGE
Grading and Irrigation
The ground surface should be sloped from the building with a minimum gradient of 5 percent for the first 10 feet. This is equivalent to 6 inches of fall across this 10-foot zone. If a 10-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
RMG – Rocky Mountain Group 11 RMG Job No. 165766
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. Irrigation should be limited to the amount sufficient to maintain vegetation. Application of more water will increase the likelihood of slab and foundation movements.
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.
Perimeter Drain
A subsurface perimeter drain is recommended around portions of the structure which will have habitable or storage space located below the finished ground surface. This includes crawlspace areas but not the walkout trench, if applicable.
The perimeter drain can be installed as an interior (if a minimum of six inches of free draining aggregate is placed beneath the slab) or exterior perimeter drain system. The perforated drainage pipe should be installed so the top of the pipe is not above the top of the footing and should be surrounded by material to reduce the infiltration of silt into the drainage pipe. The pipe should be installed in one of the following manners:
1) The pipe may be installed as level as possible as long as the pipe is placed in a minimum of six inches of gravel or crushed stone and exits into a sump pit with mechanical means to remove the water. Or
2) The pipe may be installed as a gravity system with a minimum 1/8 inch fall per 1 foot length surrounded by a minimum six inches of gravel or crushed stone that either daylights to allow free flow drainage or exits into a sump pit with mechanical means to remove the water.
RMG – Rocky Mountain Group 12 RMG Job No. 165766
A subsurface perimeter drain is designed to intercept some types of subsurface moisture and not others. Therefore, the drain could operate properly and not mitigate all moisture problems relating to foundation performance or moisture intrusion into the basement area.
CONCRETE
Sulfate testing was performed on selected samples based on ASTM C1580. Test results yielded 0.0% and 2.16% sulfate by weight, indicating the soils present high sulfate exposure. Based on these results Type V 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. Recommendations for exterior concrete slabs, such as patios, driveways, and sidewalks, are not included in this report.
CLOSING
This report has been prepared for the exclusive purpose of providing geotechnical engineering information and recommendations for development described in this report. RMG should be retained to review the final construction documents prior to construction to verify our findings, conclusions and recommendations have been appropriately implemented. This report has been prepared for the exclusive use by Journey Homes for application as an aid in the design and construction of the proposed development in accordance with generally accepted geotechnical engineering practices. The analyses and recommendations in this report are based in part upon data obtained from test borings and site observations. The nature and extent of variations may not become evident until construction. If variations then become evident, RMG should be retained to review the recommendations presented in this report considering the varied condition, and either verify or modify them in writing. Our professional services were performed using that degree of care and skill ordinarily exercised, under similar circumstances, by geotechnical engineers practicing in this or similar localities. RMG does not warrant the work of regulatory agencies or other third parties supplying information which may have been used during the preparation of this report. No warranty, express or implied is made by the preparation of this report. Third parties reviewing this report should draw their own conclusions regarding site conditions and specific construction techniques to be used on this project. The scope of services for this project does not include, either specifically or by implication, environmental assessment of the site or identification of contaminated or hazardous materials or conditions. Development of recommendations for the mitigation of environmentally related conditions, including but not limited to biological or toxicological issues, are beyond the scope of this report.
