This NATURAL HERITAGE REVIEW is not a site clearance letter. Rather, it identifies public lands and sensitive resources known to have beenlocated close to and/or potentially affected by the proposed project On-site verification is the responsibility of the project.

Heritage records wereidentified at some date and location.

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

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 specieswill not be encountered.

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

Look for additional information about the biological and habitat needs of records listed in order to avoid or minimize impacts.

Moreinformation is at http://mdc.mo,,gov/discover-nature/places-,

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

..Gray bats (Myotis federally and state listed "endangered")

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

Avoidentry 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 04for 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 halfof the state. They are found in summer months, primarily north of the Missouri River, roosting andraising 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 standingand preserve mature forest canopy. If large trees with nesting cavities or loose bark need to beremoved 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) omBonne Femme Creek to the south. Historically, they probably used Gans Creek as well. Thesefish typically occupy permanent pools of small, clear, high quality streams draining upland areas,usually on substrates of gravel, rubble, sand or bedrock.

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 streamsand rivers may be found at http://mdc.mo.qov/79.

Minimize erosion and sedimentation/runoff tonearby 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 plantspecies 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 tobuffer streams and drainages, and monitor those after rain events and until a well-rooted groundcover is reestablished.This county has known karst geologic eatures (e.g. caves, springs, and sinkholes, allcharacterized by subterranean watermovement).

Few karst features are recorded in heritagerecords, and ones not noted her my be encountered atteproject site or affected by theproject.

Cave fauna (many of wchare species of conserain concern) are influenced bychanges to water quality, so check your project site for any as features and make every effort toprotect groundwater in the project area. See http://mdc.

Based on this review, we have made the following determination:

] After review of initial submission, the project area has a low potential for the occurrence of culturalresources.

A cultural resource survey, therefore, is not warranted.

[] Adequate documentation has been provided (36 CFR Section 800.1 1). There will be "no historicproperties affected" by the current project.~An adequate cultural resource survey of the project area has been previously conducted.

It hasE~] been determined that for the proposed undertaking there will be "no historic properties affected".

For the above checked reason, the State Historic Preservation Office has no objection to the initiation of projectactivities.

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 thesubject site.Based on the information obtained from our subsurface exploration, the site can be developed forfuture construction.

The following geotechnical considerations were identified:

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

Existing fill was encountered in Borings B-3 and B-4, however we understand that thismaterial 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 ofengineered fill material.

Based on the USGS map, it appears that a pond may have been located in the vicinity oflot 16 and that the existing pond located north of the Radii Facility previously extended westonto a portion of Lot 2. We recommend these areas be thoroughly investigated during thefinal geotechnical investigation for each respective lot.* The near-surface soils are active and prone to volume change with variations in moisturecontent.

For this reason, a low volume change zone (LVC) is typically constructed beneathat-grade, grade-supported floor slabs. Depending on final grading plans, construction ofthe LVC may require overexcavation within future building pads.* On-site soils appear suitable for use as compacted structural fill; however, if they do notmeet the low plasticity fill criteria, they should not be utilized for LVC material.

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 projectsite.It is difficult to predict future sinkhole activity.

Sinkholes and caves in this area are in variousstages of development and can appear at any time. Site grading and drainage may alter siteconditions and could possibly cause sinkholes in areas that have no history of this activity.

Details for each of theborings 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 ofgroundwater.

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 theshort 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 BoringsB-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 timemay 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 surfacewater 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 inthe vicinity of the referenced project.

These sand pockets are normally discontinuous and oftencontain water of variable quality and quantity.

These sand pockets may be encountered duringfoundation excavation.

This possibility should be considered when developing design andconstruction 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 wereperformed.

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 higheror lower than the levels indicated on the boring logs. The possibility of groundwater levelfluctuations should be considered when developing the design and construction plans for theproject.Reliable u Responsive

Terracon Project No. 09105094.1.1 4.0 SITE SUITABILITY AND PRELIMINARY FINDINGS ANDRECOMMENDATIONS 4.1 Geotechnical Considerations The borings performed for this project generally encountered native lean to fat clay and fat clayunderlain by glacial drift. Existing fill was encountered in Borings B-3 and B-4 to depths of 3 to 12feet, 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 thenative clay or compacted structural fill will form the subgrade for future building foundations andfloor 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 offootings, amounts of cuts or fill, bearing material, and foundation loads. Structural loads, finalgrades, and other design details should be provided when available.

Although this reportdiscusses design parameters, these parameters are preliminary.

This preliminary report is notintended 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 sitegrading.Examination of the boring logs indicates a range of soil-moisture conditions are present at thissite. At the time of drilling, some of the soils at various depths are at moisture levels above theirmeasured plastic limit. Typically, soil with moisture levels above their measured plastic limit maybe prone to rutting,

pumping, and can develop into unstable subgrade conditions during generalconstruction operations.

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

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

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

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

Terracon Project No. 09105094.1.1 We recommend that the exposed subgrade be thoroughly evaluated after stripping of anytopsoil 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 fatclay. Shallow bedrock, karst features, or extensive pervious deposits of water-bearing sand thatcould impact site development did not appear to be present based on the preliminary site andsubsurface information gathered at this time.Based on the subsurface conditions encountered in the widely spaced borings, the site soils aresuitable for future development.

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

In our opinion, full-time testing andobservation should be employed during mass grading to evaluate compliance with projectearthwork 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 thefootings 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 placedcompacted structural fill), allowable bearing pressures would likely be in the range of 1,000 psf to3,000 psf. Due to the presence of clay soils, shallow foundations are typically soil-formed in thegeneral vicinity of this site. Further testing at the individual structure locations should beperformed to determine the appropriate bearing capacity for structural support.Heavier loads, which could cause excessive settlement, are normally supported by shallowfoundations which are supported, in turn, by aggregate-pier intermediate foundations or by drilledpiers. Pier drilling through the native soils is not expected to become difficult based upon thematerial encountered within the borings;

however, the drilled pier contractor should be preparedshould sandy zones or large boulders be encountered.

The 2006/2009 Intemational Building Code requires a site soil profile determination extending adepth of 100 feet for seismic site classification.

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

Borings for this report extended to a maximum depth ofapproximately 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 themaximum depth of the subsurface exploration.

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

Soil having high plasticity characteristics (i.e., fat clay) generally has a greater potential for moisture related volume change than less plastic materials such aslean clay. In addition, swell potential is generally greater in material with a high dry unit weightand low initial moisture content.

However, even low plasticity soils can swell significantly if theirmoisture levels are initially low.Because of the moderate to high shrink-swell potential of the lean to fat clay and fat clay soilencountered in the borings, a low volume change layer will likely be required below at-gradefloor slabs. This layer typically varies from 12 to 36 inches in thickness.

The on-site lean to fatclay and fat clay soils encountered in the borings performed for this report are typically notsuitable for use as low volume change material;

however, on-site materials may exist whichwould 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, heavytraffic from concrete trucks and other delivery vehicles disturbs the subgrade and many surfaceirregularities are filled in with loose soils to improve trafficability temporarily.

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

Pavement thickness can be determined using AASHTO, Asphalt Institute and/or other methods ifspecific 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 anddeformation due to shrink/swell related movement of the subgrade.

Expansive soils are present at this site. It is important to minimize moisture changes in thesubgrade both during construction and during the life of the pavement to reduce shrink/swell movements.

This NATURAL HERITAGE REVIEW is not a site clearance letter. Rather, it identifies public lands and sensitive resources known to have beenlocated close to and/or potentially affected by the proposed project On-site verification is the responsibility of the project.

Heritage records wereidentified at some date and location.

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

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 specieswill not be encountered.

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

Look for additional information about the biological and habitat needs of records listed in order to avoid or minimize impacts.
