EXECUTIVE SUMMARY

A geotechnical exploration has been conducted for the proposed Iowa National Guard Field

Maintenance Shop site located at 3200 Remington Avenue in Sioux City. Nine borings were conducted at this site to depths between 10 and 20 feet below existing grades to evaluate subsurface conditions and provide geotechnical recommendations for design and construction of the proposed building, parking lots, and access drives. The new slab-on-grade building will be approximately

22,000 square feet and will have a finish floor elevation near 1093.5 feet. Nathan Kress, P.E. with

KPFF indicated the new building will generate maximum continuous wall loads of 4.5 kips per lineal foot and maximum isolated column loads of 90 kips.

The following executive summary is provided for overview and omits details which are necessary for proper implementation of our geotechnical engineering recommendations. We recommend the report be read in its entirety for comprehensive understanding of the items contained herein.

Test borings encountered stiff fat clay (CH) cohesive alluvium overlying medium stiff to stiff and moist lean clay (CL) cohesive alluvium soils. The cohesive alluvium soils are underlain by granular alluvium consisting of loose to medium dense silty fine sand (SM).

With the exception of Boring No. 2 which encountered saturated sand near a depth of 9.5 feet, all borings were dry. At the time of the field exploration the stage level of the Missouri

River at Sioux City was 20 feet or more below existing grades at this site.

The fat clay (CH) cohesive alluvium soils encountered in the borings are moderately to highly expansive and can cause movements to lightly loaded footings, floor slabs, and pavements. Based on the prevalence of expansive soils at the site, the near surface moderately expansive fat clay (CH) cohesive alluvium soils will likely be present below the building floor slab and pavements placed as fill during proposed site grading and will likely require remediation. Typical remediation techniques include providing a low plasticity soil buffer a minimum of 2 feet thick below slabs and 1 foot below pavements or chemically stabilizing the on-site plastic soils by incorporating Portland cement, Class C fly ash, or quicklime.

The on-site lean clay (CL) and sandy silt (ML) cohesive alluvium and deeper silty sand

(SM) soils would be suitable for use directly below the floor slab as part of the recommended low plasticity soil buffer. However, the low clay content silt and sand will be easily disturbed by construction traffic and could warrant chemical stabilization to support construction traffic.

The on-site cohesive and underlying granular soils would provide adequate support for light to moderately loaded structures. In our opinion, the on-site soils or new engineered compacted fill would be capable of supporting a maximum net allowable bearing pressure of 2,000 pounds per square foot.

PROJECT INFORMATION

The Iowa Army National Guard (IANG), with design assistance from Farnsworth Group

(Farnsworth), Bishop Engineering Company (BEC), KPFF Consulting Engineers (KPFF) and others, is planning the construction of a new field maintenance shop to be located near 3200

Remington Avenue in Sioux City at the site depicted in the following Figure No. 1.

Figure No. 1 – Preliminary Grading Plan (BEC)

Project information was provided by the design team. The new slab-on-grade building will be approximately 22,000 square feet and will have a finish floor near elevation 1093.5 feet. Nathan

Kress, P.E. with KPFF indicated the new building will generate maximum continuous wall loads of 4.5 kips per lineal foot and maximum isolated column loads of 90 kips. Supporting facilities include pavement for parking of military and privately owned vehicles, access roads and sidewalks, a loading ramp, storm water management facilities, and required site utilities.

The site is located in an agricultural field south of the existing IANG facility between South

Bridge Road and Harbor Drive. The site is located within the former floodplain of the Missouri

River and existing grades vary between 1088 and 1092 feet. The area near the proposed building appears to have been used as a borrow site in the past. Topographic site plans indicate the upper 3 to 4 feet of the soils in this area have been removed. Based on the proposed grading plan we interpret cut and fill depths of 5 feet or less are expected at this site including new fill thicknesses on the order of 4 feet below the building.

FIELD EXPLORATION

Nine borings were conducted at this site to depths between 10 and 20 feet below existing grades on July 19, 2023. Approximate locations of the borings are shown on the enclosed Site Plan and were measured in the field from existing landmarks. The actual boring locations and surface elevations, indicated on the enclosed Boring Logs, were determined and provided by BEC after completion of the field exploration. Methods of drilling, sampling, standard laboratory testing, and classifying of subsurface materials are discussed in the Boring Log Description/Legend pages of the Appendix.

SUBSURFACE CONDITIONS

Soil Profile

Detailed descriptions of soils encountered by this exploration are provided on the Boring

Logs enclosed in the Appendix. The Profile of Borings (Plates A-1 and A-2) depicts the relative deposit elevations in the borings below the building (Plate A-1) and other areas of the site (Plate

A-2). Following is a discussion of the subsurface materials encountered in the borings. Unless otherwise indicated, the depths of soil stratum and groundwater levels are referenced from below existing grade at the individual boring locations at the time of drilling.

Dark brown to brown fat clay (CH) cohesive alluvium was present at the ground surface in all borings. The damp cohesive alluvium extended to depths between 3.5 and 7 feet. Brown sandy silt (ML) and brown lean clay (CL) cohesive alluvium underlaid the fat clay (CH) alluvium in

Boring Nos. 1, 2, 3, and 4. The cohesive alluvium extended to depths between 7 and 8.3 feet in Boring Nos. 1, 2, and 3. Boring Nos. 4 and 8 terminated in medium stiff cohesive alluvium near depths of 10 and 15 feet, respectively.

Silty fine sand (SM) granular alluvium underlaid the upper cohesive alluvium in all borings. In general, sand was encountered between below depths of 3.5 to 8.3 feet in the borings.

Cohesive alluvium layers consisting of lean to fat clay (CL-CH) and lean clay (CL) were encountered within the granular alluvium with varying depths and thicknesses. Boring Nos. 1, 2, 3, 5, 6, 7, and 9 terminated in loose to medium dense granular alluvium between depths of 10 and

20 feet.

Groundwater Level Observations

The borings were monitored during and shortly after drilling operations to detect moisture seepage and groundwater accumulation. The results of our groundwater level observations are noted on the Boring Logs enclosed in the Appendix.

During drilling operations, saturated sand was observed near a depth of 9.5 feet in Boring

No. 2. No moisture seepage or groundwater accumulation was observed in any of the remaining borings. These short-term groundwater levels are not necessarily a true indication of the groundwater table. Long-term observations would be necessary to accurately define the groundwater variations at this site.

Fluctuation of groundwater levels can occur due to seasonal variations in the amount of rainfall, surface drainage, subsurface drainage, site topography, irrigation practices, ground cover, and stage level of the nearby Missouri River. At the time of this field exploration the stage level of the Missouri River at Gauge No. 06486000 at Sioux City approximately 8 miles upriver was about 20 feet or more below existing grade at the site or approximately elevation 1070 feet.

ANALYSIS AND RECOMMENDATIONS

Expansive Soils

The fat clay (CH) cohesive alluvium soils encountered in the upper 3.5 to 7 feet of the borings are moderately to highly plastic (Liquid Limit (LL) of 59 and Plasticity Index (PI) of 40 and considered expansive. These soils are subject to volumetric change with changes in soil moisture content which can cause movement and distress to lightly loaded footings, floor slabs, and pavements. The most severe problems occur where higher clay content soils are in a natural state of low moisture or are highly compacted at moisture contents near or below optimum moisture content on a relatively incompressible base. Subsequent moisture content increases below the floor slab or pavement after construction then cause the moderately expansive soils to swell appreciably. If the moisture content does not fluctuate much, then the soil swelling and heave will be minor.

Existing grades within the footprint of the proposed building area are near elevations 1089 feet and will require approximately 4 feet of new engineered fill to achieve the desired finish floor elevation near 1093.5 feet. Therefore, we anticipate exterior foundations may bear near or slightly above existing grades on or slightly above the damp fat clay (CH) cohesive alluvium. The highly desiccated (dry) soils are 3 to 9 percent below optimum moisture content and, in our opinion, would have a higher risk for swelling post-construction. To reduce the risk of swelling post-construction, we recommend after site stripping the upper 1 foot of fat clay (CH) cohesive alluvium soils below the building footprint be moisture conditioned to +1 to +4 percent of optimum moisture content and recompacted to a minimum of 95% maximum dry density (ASTM D698) in order to reduce the swell potential of these soils below the building.

To reduce the potential for future floor slab movement due to moderately expansive soils, we recommend floor slabs bear on 2 feet or more of low plasticity cohesive (Liquid Limit of 45 or less and Plasticity Index of 23 or less) or cohesionless soils. Based on a finish floor near elevation

1093.5 feet we assume floor slabs will bear on 2 feet of new low plasticity engineered compacted fill placed coincidental to site grading. Low plasticity cohesive soils (LL≤45 and PI≤23) or cohesionless soils should be specified for use as fill within 2 feet below the building floor slab.

Anticipated shallow cuts in most areas of the site and low availability of on-site low plasticity cohesive soils within in the upper 6 to 8 feet, we expect it may be necessary to import suitable low plasticity fill. We recommend ABE test and approve the fill prior to importing to the site.

As an alternative to importing low plasticity soils, the on-site plastic soils could be chemically stabilized using Class C fly ash, Portland cement, or dolomitic quicklime and used directly below the building footings and floor slab.
