This NATURAL HERITAGE REVIEW is not a site clearance letter. Rather, it identifies public lands and sensitive resources known to have been located close to and/or potentially affected by the proposed project On-site verification is the responsibility of the project. Heritage records were identified at some date and location.

This report considers records near but not necessarily at the project site. Animals move and, over time, so do plant communities.

To say "there is a record" does not mean the species/habitat is still there. To say that "there is no record" does not mean a protected species will not be encountered.

These records only provide one reference and other information (e.g. wetland or soils maps, on-site inspections or sulveys) should be considered.

Look for additional information about the biological and habitat needs of records listed in order to avoid or minimize impacts. More information is at http://mdc.mo,,gov/discover-nature/places-, o/natural-areas and mdc4.mdc.mo.gov/applications/mofwis/mofwis searchl1.aspx.

Activities that alter, destablie or destroy stream bottoms or banks should be avidd from March 15 to June 15 in order not to dsrupt spawning (laying and fertilizing fish eggs!,-At all times, avoid habitat destruction or introducingheavy sediment loads, chemical or organi po:!llutants.

Within its premises are records of of conseration concern, including bot ray (2002 and (2007) bat records. *..Gray bats (Myotis federally and state listed "endangered")

are likely to occur in the project area, as thy oag ver streams, rivers, and in thi part of Missouri.

Avoid entry or disturbac of any cave inhabited by gray bats an he osible retain forest vegetation along the stream and from the gray bat cave opening to the stream. See http://mdc.mo..qov/1 04 for best management recommendations.

>' Indiana bats (Myotis sodalis, federally ad s tat e lite 'endangered")

may occur in this area.These mammals hibernate durin wntermothsincavesl in issouri primarily in the southern half of the state. They are found in summer months, primarily north of the Missouri River, roosting and raising young under the bark of trees in riparian forests and upland forests near perennial streams.During project activities, avoid degrading stream quality and where possible leave snags standing and preserve mature forest canopy. If large trees with nesting cavities or loose bark need to be removed by your project, that should be done between November and March. Additional information to incorporate in planning documents is available at http://mdc.mo..qov/1 10.> Topeka shiners (Notropis Topeka, federal- and state-listed "endangered")

are recorded (1997) om Bonne Femme Creek to the south. Historically, they probably used Gans Creek as well. These fish typically occupy permanent pools of small, clear, high quality streams draining upland areas, usually on substrates of gravel, rubble, sand or bedrock.

doc, page 1 of 2 shiners may be found at http://mdc.mo.qiov/1 37*General recommendations related to this project or site, or based on information about the historic range of species (unrelated to any specific heritage records):

in the area should be protected from soil erosion, water pollution and in-stream activities that modify or diminish aquatic habitats*

Best management recommendations relating to streams and rivers may be found at http://mdc.mo.qov/79.

Minimize erosion and sedimentation/runoff to nearby streams and lakes, including adherence to any "Clean Water Permit" conditions.

Revegetate areas in which the natural cover is disturbed to minimize erosion using native plant species compatible with the local landscape and wildlife needs. Pollutants, including sediment, can have significant impacts far downstream.

Use silt fences and/or vegetative filter strips to buffer streams and drainages, and monitor those after rain events and until a well-rooted ground cover is reestablished.This county has known karst geologic eatures (e.g. caves, springs, and sinkholes, all characterized by subterranean watermovement).

Few karst features are recorded in heritage records, and ones not noted her my be encountered atteproject site or affected by the project. Cave fauna (many of wchare species of conserain concern) are influenced by changes to water quality, so check your project site for any as features and make every effort to protect groundwater in the project area.

Populations§ have been in serious decline for decades, and have reched a point where greater prairie chickens could be gone from Missouri within a few yers. The dominant.

factor in their decline is of. native prairie habitats to other uses. Other praire dependent species are also in seriu decline for the same reason.

SUMMARY

A preliminary geotechnical investigation has been performed for the proposed certified site which consists of Lots 2, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17 and 18 of the Discovery Ridge Research Park in southeastern Columbia, Missouri.

Nine (9) borings, designated B-I through B-9, were performed to depths of approximately 13 to 20 feet below the existing ground surface at the subject site.Based on the information obtained from our subsurface exploration, the site can be developed for future construction.

The following geotechnical considerations were identified:

Typical lightly loaded commercial buildings may be supported on shallow footings bearing on stiff to very stiff native clay or on compacted structural fill.* Assuming proper site preparation and any necessary subgrade repair, total and differential settlement should be within anticipated client/owner specifications.

Existing fill was encountered in Borings B-3 and B-4, however we understand that this material was placed as part of mass grading during mid to late 2008. At that time, Terracon was onsite to observe and test the density and moisture during placement of engineered fill material.* Based on the USGS map, it appears that a pond may have been located in the vicinity of lot 16 and that the existing pond located north of the Radii Facility previously extended west onto a portion of Lot 2. We recommend these areas be thoroughly investigated during the final geotechnical investigation for each respective lot.* The near-surface soils are active and prone to volume change with variations in moisture content. For this reason, a low volume change zone (LVC) is typically constructed beneath at-grade, grade-supported floor slabs. Depending on final grading plans, construction of the LVC may require overexcavation within future building pads.* On-site soils appear suitable for use as compacted structural fill; however, if they do not meet the low plasticity fill criteria, they should not be utilized for LVC material.* The 2006/2009 International Building Code (IBC), Table 1613.5.2 seismic site classification for this site is C* The Modified Mercalli Intensity Scale for seismic events for Boone County is VII.Reliable m Responsive

Highly plastic clays that exhibit volume change with variations in moisture are commonly encountered near the ground surface.Based on the 2003 Geologic Map of Missouri, Missouri Department of Natural Resources, bedrock at this site consists primarily of the Pennsylvanian aged Cherokee Group (Pc), the Pennsylvanian aged Marmaton Group (Pm), and the Mississippian aged Burlington formation (Mo). The Cherokee Group is predominantly shale with minor amounts of carbonates and sandstone.

This group contains most of the mineable coal beds in Missouri.

The Marmaton Group consists of a succession of shale, limestone, clay, and coal beds.Reliable

Solution features, including caves and sinkholes, are commonly present in this formation.

No caves or sinkholes are known to exist, or are published to exist, within approximately 1 mile of this project site.However several areas of known karst activity are present west and southwest of the project site.It is difficult to predict future sinkhole activity.

Sinkholes and caves in this area are in various stages of development and can appear at any time. Site grading and drainage may alter site conditions and could possibly cause sinkholes in areas that have no history of this activity.3.2 Typical Profile Based on the results of the borings, as follows: subsurface conditions on the project site can be generalized Stratum Approximate Depth to Mtra ecito ossec/est Stratum Bottom of Stratum (feet) Mtra ecito ossec/est Surface 0.2 to 0.5 Topsoil: brown, friable and contained N/A significant organic matter 3 to 12 Existing Fill ' consisting of lean clay 1 and lean to fat clay with Very stiff to hard (Borings B-3 & B-4 only) varying amounts of sand and gravel 2 3 to 12 Lean clay, lean to fat clay and fat clay Stiff to very stiff Undeermned BorngsB-i Lean to fat clay and fat clay with through B-5, B-B and B-9 varying amounts of sand, gravel andStftohr 3 teminaed wthi thi strtum possible cobbles (visually classified as at the planned depth of glacial drift)approximately 20 feet __________________________

Details for each of the borings can be found on the boring logs in Appendix A of this report.3.3 Groundwater The boreholes were observed while drilling and after completion for the presence and level of groundwater.

Groundwater was observed at in Borings B-5 and B-6 at depths of approximately 12 to 18.5 feet. Groundwater was not observed in the remaining borings during drilling or for the short amount of time the borings were allowed to remain open following drilling completion.

However, this does not necessarily mean that stable groundwater levels were observed in Borings B-5 and B-6, or that the remaining borings were terminated above groundwater.

Due to the low permeability of the soils encountered in the borings, a relatively long period of time may be necessary for a groundwater level to develop and stabilize in a borehole in these materials.

Long term observations in piezometers or observation wells sealed from the influence of surface water are often required to define groundwater levels in materials of this type.Pockets, lenses, and stringers of sand are sometimes encountered in the glacial soils found in the vicinity of the referenced project. These sand pockets are normally discontinuous and often contain water of variable quality and quantity.

These sand pockets may be encountered during foundation excavation.

This possibility should be considered when developing design and construction plans and specifications for the project.Groundwater level fluctuations occur due to seasonal variations in the amount of rainfall, runoff, proximity to existing ponds, and other factors not evident at the time the borings were performed.

In addition, perched water can develop over low permeability soil strata. Therefore, groundwater levels during construction or at other times in the life of the structure may be higher or lower than the levels indicated on the boring logs. The possibility of groundwater level fluctuations should be considered when developing the design and construction plans for the project.Reliable u Responsive

Terracon Project No. 09105094.1.1 4.0 SITE SUITABILITY AND PRELIMINARY FINDINGS AND RECOMMENDATIONS 4.1 Geotechnical Considerations The borings performed for this project generally encountered native lean to fat clay and fat clay underlain by glacial drift. Existing fill was encountered in Borings B-3 and B-4 to depths of 3 to 12 feet, and limestone bedrock was encountered in Borings B-6 and B-7 at depths of approximately 17 and 12.5 feet, respectively.

Depending on final site grading plans, we anticipate that either the native clay or compacted structural fill will form the subgrade for future building foundations and floor slabs.Based on the USGS map, it appears that a pond may have been located in the vicinity of lot 16.Further, based on aerial photography the existing pond located north of the Radii Facility previously extended southwest onto a portion of Lot 2. We recommend these areas be thoroughly investigated during the final geotechnical investigation for each respective lot.Performance of foundations depends on many factors including, but not limited to, the depth of footings, amounts of cuts or fill, bearing material, and foundation loads. Structural loads, final grades, and other design details should be provided when available.

Although this report discusses design parameters, these parameters are preliminary.

This preliminary report is not intended to be relied upon for final design. We recommend a more detailed study be performed when specific project details are known, and/or possibly following completion of general site grading.Examination of the boring logs indicates a range of soil-moisture conditions are present at this site. At the time of drilling, some of the soils at various depths are at moisture levels above their measured plastic limit. Typically, soil with moisture levels above their measured plastic limit may be prone to rutting, pumping, and can develop into unstable subgrade conditions during general construction operations.

Moderately to highly plastic, lean to fat clay and fat clay soils were present on site. Such soils are commonly referred to as "expansive" or "swelling" soils because they expand or swell as their moisture contents increase.

However, these soils also "contract" or "shrink" as their moisture levels decrease.

Footings, floor slabs, and pavements supported on expansive soils will move upward and downward and such movements will result in distortion, possibly causing cracking or structural damage to structures.

For this reason, a low volume change zone will likely be required beneath at-grade floor slabs. We recommend that additional laboratory testing be performed during the final geotechnical exploration to better evaluate the expansive nature of these soils.Reliable

Terracon Project No. 09105094.1.1 We recommend that the exposed subgrade be thoroughly evaluated after stripping of any topsoil and creation of all cut areas, but prior to the start of any fill operations.

We recommend that the geotechnical engineer be retained to evaluate the bearing material for the foundations and floor slab subgrade soils. Subsurface conditions, as identified by the field and laboratory testing programs, have been reviewed and evaluated with respect to the proposed development plans known to us at this time.4.2 Earthwork The widely spaced preliminary borings typically encountered stiff to hard lean to fat clay and fat clay. Shallow bedrock, karst features, or extensive pervious deposits of water-bearing sand that could impact site development did not appear to be present based on the preliminary site and subsurface information gathered at this time.Based on the subsurface conditions encountered in the widely spaced borings, the site soils are suitable for future development.

Additional borings should be completed so that each site can be adequately characterized and recommendations can be more fully developed to assist and guide future mass grading.Recommendations will need to be developed for site preparation and proof-rolling operations as well as construction of cut and structural fill operations.

In our opinion, full-time testing and observation should be employed during mass grading to evaluate compliance with project earthwork recommendations and requirements.

If site grading results in relatively thick structural fills, settlement and cut/fill slope stability may need to be evaluated.

4.3 Foundations

Shallow foundations could be used to support lightly loaded commercial structures provided the footings are supported by suitable material (stiff to hard native clay or compacted structural fill).Depending on the design footing elevation and bearing material (native clay or newly placed compacted structural fill), allowable bearing pressures would likely be in the range of 1,000 psf to 3,000 psf. Due to the presence of clay soils, shallow foundations are typically soil-formed in the general vicinity of this site. Further testing at the individual structure locations should be performed to determine the appropriate bearing capacity for structural support.Heavier loads, which could cause excessive settlement, are normally supported by shallow foundations which are supported, in turn, by aggregate-pier intermediate foundations or by drilled piers. Pier drilling through the native soils is not expected to become difficult based upon the material encountered within the borings; however, the drilled pier contractor should be prepared should sandy zones or large boulders be encountered.

The current scope requested does not include the required 100 foot soil profile determination.

Borings for this report extended to a maximum depth of approximately 20 feet and this seismic site class assignment considers that shale or limestone bedrock is present within approximately 30 feet of the ground surface and continues below the maximum depth of the subsurface exploration.

Additional exploration to greater depths could be considered to confirm the conditions below the current depth of exploration.

Altematively, a geophysical exploration could be utilized in order to attempt to justify a more favorable seismic site class.Reliable

Soil having high plasticity characteristics (i.e., fat clay) generally has a greater potential for moisture related volume change than less plastic materials such as lean clay. In addition, swell potential is generally greater in material with a high dry unit weight and low initial moisture content. However, even low plasticity soils can swell significantly if their moisture levels are initially low.Because of the moderate to high shrink-swell potential of the lean to fat clay and fat clay soil encountered in the borings, a low volume change layer will likely be required below at-grade floor slabs. This layer typically varies from 12 to 36 inches in thickness.

The on-site lean to fat clay and fat clay soils encountered in the borings performed for this report are typically not suitable for use as low volume change material; however, on-site materials may exist which would meet the low volume change material criteria.

Further testing at the individual structure locations should be performed to determine the required low volume change layer thickness.

4.6 Pavements On most project sites, the site grading is accomplished relatively early in the construction phase.Fills are placed and compacted in a uniform manner. However, as construction proceeds, excavations are made into these areas, rainfall and surface water saturates some areas, heavy traffic from concrete trucks and other delivery vehicles disturbs the subgrade and many surface irregularities are filled in with loose soils to improve trafficability temporarily.

As a result, the pavement subgrades, initially prepared early in the project, should be carefully evaluated as the time for pavement construction approaches.

Pavement thickness can be determined using AASHTO, Asphalt Institute and/or other methods if specific wheel loads, axle configurations, frequencies, and desired pavement life are provided.Pavement design methods are intended to provide structural sections with adequate thickness over a particular subgrade such that wheel loads are reduced to a level the subgrade can support.The support characteristics of the subgrade for pavement design do not account for shrink/swell movements of an expansive clay subgrade such as the soils encountered on this project. Thus, the pavement may be adequate from a structural standpoint, yet still experience cracking and deformation due to shrink/swell related movement of the subgrade.Expansive soils are present at this site. It is important to minimize moisture changes in the subgrade both during construction and during the life of the pavement to reduce shrink/swell movements.
