The evaluation was conducted in accordance with our agreement for geotechnical engineering services to Ironbridge Homes, LLC dated January 21, 2005. The data obtained and our current findings of future subsidence potential are presented in this report. Previous Geotechnical Stndy: Hepworth-Pawlak Geotechnical previously conducted subsurface exploration for the subdivision development and the foundation bearing conditions on Lot 147, and presented our findings in reports dated September 10, 1998, Job No. 197 327, and October 11,2004, Job No. 101196-1. The exploration identified the shallow subsurface conditions for foundation design in the area of Lot 14 7. The current study was performed to evaluate the deeper subsurface materials for future subsidence potential related to the underlying Eagle Valley Evaporite. Subsurface Conditions: One exploratory boring was drilled on the lot as shown on Figure 1. The log of the boring is presented on Figure 2. The subsoils below about 62 feet of debris fan soils consist of dense, river gravel alluvium to a depth of 73 feet overlying claystone/siltstone of the Eagle Valley Evaporite. The drilling conditions indicate that the subsurface materials are competent for the residence support and no voids were encountered to the drilled depth of 96 feet. Future Subsidence Potential: Eagle Valley Evaporite underlies the Ironbridge Development and is known to be associated with sinkholes and localized ground subsidence in the Roaring Fork River valley. A sinkhole vyas identified during our previous study for the subdivision development that is located within a fairway about 750 feet to the northeast of the subject lot. Indications of ground subsidence were not identified prior to development in the area of the lot, and voids that could indicate a ris)c of future ground subsidence were not encountered in the boring drilled on the lot. In our opinion, the risk of future ground subsidence on Lot 147 tbroughout the service life of the residence is low and similar to other areas of the Roaring Fork River valley where there have not been indications of ground subsidence. Parker 303-841-7119 • Colorado Springs 719-633-5562 • Silverthorne 970-468-1989 -2- Limitations: This study has been conducted in accordance with generally accepted geotechnical engineering principles and practices in this area at this time. We make no warranty either express or implied. The conclusions submitted in this report are based upon the data obtained from the subsurface exploration, the proposed type of construction, and our experience in the area. Our fmdings include extrapolation of the subsurface conditions identified at the exploratory boring and there could be variations in the subsurface conditions. This report has been prepared for the use by our client for subsidence potential evaluation. We are not responsible for technical interpretations by others of our infonnati.on.

The project site is shown on Figure 1. The purpose of the study was to develop recommendations for the foundation design. The study was conducted as a supplement to our agreement for geotechnical engineering services to L.B. Rose Ranch, LLC dated July 24, 2003. We previously conducted subsurface exploration to evaluate the collapse potential for the non-irrigated debris fan areas within the development and presented our findings in a report dated September 10, 1998, Job No. 197 327. An exploratory boring was drilled on the lot to obtain information on the general subsurface conditions. Samples of the subsoils obtained during the field exploration were tested in the laboratory to determine their classification, compressibility or swell and other engineering characteristics. The results of the field exploration and laboratory testing were analyzed to develop recommendations for foundation types, depths and allowable pressures for the proposed building foundation. This report summarizes the data obtained during this study and presents our conclusions, design recommendations and other geotechnical engineering considerations based on the proposed construction and the subsurface conditions encountered. PROPOSED CONSTRUCTION The specific building plan for the lot had not been determined at the time of our study. The proposed residence will generally be a one and two story wood fi-ame structure between about 2,500 and 3,000 square feet in size. Ground floor will be slab-on-grade and/or structural above crawlspace. A partial basement level may be provided. Grading for the structure is assumed to be relatively minor with cut depths between about 3 to 6 feet. We assume relatively light foundation loadings, typical of the proposed type of construction. Job No. 101 196-1 ~h -2- If building loadings, location or grading plans change significantly from those described above, we should be notified to re-evaluate the recorrunendations contained in tllis report. SITE CONDITIONS The lot is located in the up !rill, southwestern part of the development and was vacant at the time of our field exploration. The Jot location is shown on Figure 1. The roadway and underground utility construction to the lot are complete. Shallow cuts and fill were observed on the lot from overlot grading as part of the subdivision development. The ground surface is relatively flat with a gentle slope down to the southeast with about 2 feet of elevation difference across the building area. The native vegetation had been stripped during the previous overlot grading. GEOLOGY The geologic conditions were descn"bed in our previous report conducted for planning and preliminary design of the subdivision development, dated October 29, 1997, Job No. 197 327. The southwest part of the subdivision is located above the historically irrigated area on a relatively large debris fan that has been shown to be hydro compressive (settlement potential when wetted). A boring drilled in tllis general area encountered · hydro compressive soils to a depth of about 75 feet where dense river gravels were encountered. The underlying bedrock consists of the Eagle Valley Evaporite which contains gypsum and is generally associated with scattered sinkhole development in the Roaring Fork River valley. The potential for subsidence due to dissolution of the evaporite throughout the service life of the residence, in our opinion, is low. If further evaluation of the sinkhole potential on the lot is desired, we should be contacted. Job No. 10\ \96-\ ~tech -3- FIELD EXPLORATION The field exploration for the project was conducted on October 1, 2004. One exploratory boring was drilled at the location shown on Figure 1 to evaluate the subsurface conditions. The boring was advanced with 4 inch diameter continuous flight augers powered by a truck-mounted CME-45B drill rig. The boring was logged by a representative of Hepworth-Pawlak Geotechnical, Inc. Samples of the subsoils were taken with 1 inch and 2 inch I.D. spoon samplers. The samplers were driven into the subsoils at various depths with blows from a 140 pound hammer falling 30 inches. This test is similar to the standard penetration test described by ASTM Method D-1586. The penetration resistance values are an indication of the relative density or consistency of the subsoils. Depths at which the samples were taken and the penetration resistance values are shown on the Log of Exploratory Boring, Figure 2. The samples were returned to our laboratory for review by the project engineer and testing. SUBSURFACE CONDITIONS A graphic log ofthe subsurface conditions encountered at the site is shown on Figure 2. The subsoils consist of about Yz foot of granular fill and 7 feet of medium stiff, sandy silt and clay overlying medium dense/stiff to very stiff, clayey sand and silt with scattered rock fragments to the boring depth of26 feet. Laboratory testing performed on samples obtained from the boring included natural moisture content, density and finer than ·sand size gradation analyses. Results of swell- consolidation testing perfonned on a relatively undisturbed drive sample of silt, presented on Figure 4, indicate low compressibility under existing dry moisture conditions and light loading and a minor collapse potential (settlement under const<l!lt load) when wetted. The sample showed moderate compressibility upon increased loading after wetting. The laboratory testing is summarized in Table 1. Job No. JOJ l96-l -4- No :free water was encountered in the boring at the time of drilling and the subsoils were slightly moist. FOUNDATION BEARING CONDITIONS The collapse potential of the subsoils encountered at the site appears consistent with our previous findings for the non-irrigated areas of the development. The subsurface conditions and laboratory test result.~ indicate that the debris fan soils generally have lot to moderate collapse potential. There is a risk of settlement and distress to the building, driveway and utilities founded on the relatively dry debris fan deposits if the subsoils were to become wetted. The magnitude of settlement will depend on the depth and extent of wetting and structural loading. Lightly loaded spread footings placed on the natural soils should be suitable for support of the residence with a risk of settlement and distress if the bearing soils become wetted. Precautions to prevent wetting of the bearing soils need to be taken. These include: l) proper placement and compaction of backfill; 2) positive backfill slopes next to foundations; 3) restricted landscape irrigation and/or use ofxeriscape; and 4) gutters to prevent roofrunoffnearthe building. Extensive wetting such as from water line leaks and heavy irrigation could result in excessive settlements and distress. The settlement potential and risk of distress can be reduced by supporting the building on a stiffened slab (mat) foundation, or ground improvements, such as removal and replacement of native soils compacted to at least 95% of standard Proctor density at a moisture content at to 2% above optimum. We expect that ground modifications would be limited to the upper 5 to 10 feet. Recommendations for spread footings are presented below. If other foundation types and subgrade treatment methods are proposed, we should be contacted. Job No. 101 196·1 -5- DESIGN RECOMMENDATIONS FOUNDATIONS Considering the subsurface conditions encountered in the exploratory boring and the nature of the proposed construction, we believe the residence can be founded with spread footings bearing on the natural subsoils with some risk of settlement and distress if the bearing soils become welted. The design and construction criteria presented below should be observed for a spread footing foundation system. 1) Footings placed on the undisturbed natural subsoils should be designed for an allowable bearing pressure of 1,000 psf. Based on experience, we expect initial settlement offootings designed and constructed as discussed in tl:ris section will be less than 1 inch. Additional settlement of about 2 inches or more could occur if the subsoils become wetted. 2) The footings should have a minimum width of 20 inches for continuous walls and 2 feet for isolated pads. 3) Exterior footings and footings beneath unheated areas should be provided with adequate soil cover above their bearing elevation for frost protection. Placement of foundations at least 36 inches below exterior grade is typically used in this area. 4) The foundation should be constructed in a "box like" configuration rather than isolated spread footings. The foundation walls should be heavily· reinforced top and bottom and designed to span local anomalies such as by assuming an unsupported length of at least 15 feet. Foundation walls acting as retaining structures should also be designed to resist lateral earth pressures as discussed in the "Foundation and Retaining Walls" section of this report. Job No.I OJ 196·1 ~tech -6- 5) The existing fill and any loose disturbed soils should be removed and the footing bearing level extended down to the undisturbed natural soils. The exposed soils in footing area should then be moistened and compacted. 6) A representative of the geotechnical engineer should observe all footing excavations prior to concrete placement to evaluate bearing conditions. FOUNDATION AND RETAINJNG WALLS Foundation walls and retaining structures which are laterally supported and can be expected to undergo only a slight amount of deflection should be designed for a lateral earth pressure computed on the basis of an equivalent fluid unit weight of at least 55 pcf for backf!ll consisting of tl1e on-site soils. Cantilevered retaining structures which are separate from the residence and can be expected to deflect sufficiently to mobilize the full active earth pressure condition should be designed for a lateral earth pressure computed on fue basis of an equivalent fluid unit weight of at least 50 pcf for backfill consisting of the on-site soils. All foundation and retaining structures should be designed for appropriate hydrostatic and surcharge pressures such as adjacent footings, traffic, construction materials and equipment. The pressures recommended above assume drained conditions behind the walls and a horizontal backfill surface. The buildup of water behind a wall or an upward sloping backfill surface will increase the lateral pressure imposed on a foundation wall or retaining structure. An underdrain should be provided to prevent hydrostatic pressure buildup behind walls. Backfill should be placed in unifonn lifts and compacted to at least 90% of the maximum standard Proctor density at a moisture content near optimum. Backfill in pavement and walkway areas should be compacted to at least 95% of the maximum standard Proctor density. Care should be taken not to overcompact the backfill or use large equipment near the wall, since this could cause excessive lateral pressure on tl1e wall. Some Job No. !0\ \96-\ -7- settlement of deep foundation wall backfill should be expected, even if the material is placed correctly, and could result in distress to facilities constructed on the backfill. The lateral resistance of foundation or retaining wall footings will be a combination of the sliding resistance of the footing on the foundation materials and passive earth pressure against the side of the footing. Resistance to sliding at the bottoms of the footings can be calculated based on a coefficient of fiiction of.0.35. Passive pressure of compacted backfill against the sides of the footings can be calculated using an equivalent fluid unit weight of 300 pcf. The coefficient of fiiction and passive pressure values recommended above assume ultimate soil strength. Suitable factors of safety should be included in the design to limit the strain which will occur at the ultimate strength, particularly in the case of passive resistance. Fill placed against the sides of the foot1ngs to resist lateral loads should be compacted to at least 95% of the maximum standard Proctor density at a moisture content near optimum. FLOOR SLABS The natural on-site soils, exclusive of topsoil, are suitable to support lightly loaded slab- on-grade construction. The soils are compressible when welted under load and there could be some post-construction slab settlement and distress if the sub grade soils become wet. To reduce the effects of some differential movement, non-structural floor slabs should be separated from all bearing walls and columns with expansion joints which allow unrestrained vertical movement. Floor slab control joints should be used to reduce damage due to shrinkage cracking. The requirements for joint spacing and slab reinforcement should be established by the designer based on experience and the intended slab use. A minimum 4 inch layer of free-draining gravel should be placed beneath basement level slabs to facilitate drainage. This material should consist of minus 2 inch aggregate with at least 50% retained on the No.4 sieve and less than 2% passing the No. 200 sieve. Job No. 101196-l -8- All fill materials for support of floor slabs should be compacted to at least 95% of maximum standard Proctor density at a moisture content near optimum. Required fill can consist of the on-site soils devoid of vegetation, topsoil and oversized rock. UNDERDRAIN SYSTEM Although free water was not encountered during our exploration, it has been our experience in the area that local perched groundwater can develop during times of heavy precipitation or seasonal runoff. Frozen ground during spring runoff can create a perched condition. We recommend below-grade construction, such as retaining walls and basement areas, be protected from wetting and hydrostatic pressure buildup by an underdrain system. An underdrain should not be provided around shallow foundations such as crawlspace and garage areas. The drains should consist of drainpipe placed in the bottom of the wall backfill surrounded above the invert level with free-draining granular material. The drain should be placed at each level of excavation and at least 1 foot below lowest adjacent :frnish grade and sloped at a minimum 1% to a suitable gravity outlet or sump and pump. Free- draining granular material used in the underdrain system should contain less than 2% passing the No. 200 sieve, less than 50% passing the No. 4 sieve and have a maximum size of 2 inches. The drain gravel backfill should be at least 1 Y, feet deep. An i.mpervions membrane such as 20 mil PVC shonld be placed beneath the drain gravel in a trough shape and attached to tlie foundation wall with mastic to prevent wetting of the bearing soils. SURF ACE DRAINAGE Developing and maintaining positive drainage throughout the life of the residence is critical to limiting potential settlement and distress to the building. The following drainage precautions should be observed during construction and maintained at all times after the residence has been completed: Job No. 101196-1 -9- I) Uncontrolled wetting of the foundation excavations and underslab areas should be avoided during construction. 2) Exterior backfill should be adjusted to near optimum moisture and compacted to at least 95% of the maximum standard Proctor density in pavement and slab areas and to at least 90% of the maximum standard Proctor density in landscape areas. 3) The ground surface surrounding the exterior of the building should be sloped to drain away from the foundation in all directions. We recommend a minimum slope of 12 inches in the first 10 feet in unpaved areas and a minimum slope of 3 inches in the first 10 feet in paved areas. Free-draining wall backfill should be capped with about 2 feet of the on- site, fine-grained soils to reduce smface water infiltration. 4) Roof gutters should be provided with downspouts that discharge well beyond the limits of all backfill. 5) Irrigation sprinkler heads and landscaping which requires regular heavy irrigation, such as sod, should be located at least 10 feet from foundation walls. Consideration should be given to use of xeriscape to reduce the potential for wetting of soils below the building caused by irrigation.

The study was conducted as verbally authorized by Dave Ockers. The data obtained and our findings based on the subsurface conditions encountered are presented inthis report. . . Existing Construction: The residenc~.(show home and offices). on Lot 166 has experienced settlement and distress mainly on the west side. Surface drauiage is relatively poor in a flat graded swale and next to the garage where roof runoff has been blocked by a sidewalk. The north part of the crawlspace ofthe residence on Lot 165 has experienced recurring water buildup below the radon mell1brane. It has been speculated that the water is from irrigation seepage through the sewer line trench but could also be from roofdownspout pipe leakage. We understand that the residence on Lot 147 has experienced settlement and distress in the north and west parts. The west end of Lot 166 residence has apparently settled 3 to 4 inches and ground stabilization with compaction grouting has been proposed. It is also required that surface drainage be improved to effectively drain the perimeter slopes and drainage swale. The residence on Lot 165 reportedly has not experienced excessive settlements. Remedial repair plan for the residence on Lot 14 7 has not been developed. Parker 303-841-7119 • Colorado Springs 719-633-5562 • Silverthorne 970-468-1989 · -2- Subsurface Conditions: The subsurface conditions at the site were evaluated by drilling five exploratory borings at the approximate locations shown on Figure 1. The logs of the borings are presented on Figure 2. The subsoils encountered, typically below about 5 to I 0 feet ofbackfill, consist of sandy silt to silty sand with scattered gravel to depths of 67 and 68 feet on Lot 166 and 72 feet in the roadway, overlying dense river gravel alluvium. Previous drilling encountered river gravel alluvium at a depth of about 60 feet on Lot 165 and 62 feet on Lot 147. Results of laboratory testiog performed on samples taken from the borings are presented on Figure 2 and summarized in Table 1. No free water was encountered in the borings at the time of drilling. The depth of wetting appeared to be on the order of 35 to 40 feet at Boring 1, 15 to 20 feet at Boring 2, about I 0 feet at Boring 3, :about 25 feet at Boring 4 and about 35 feet at Boring 5. The soils encountered at greater depth were slightly moist and no free water was encountered. Preliminary Findings: The soils encountered below the western part of the residence on Lot 166 and at Lot 147 appear to have been deep wetted resulting inthe building settlement. Compaction grouting to the full depth of the debris fan soils can be used to · mitigate the bmidirig ·settlement .. The grouting could be terminated at the botto~ of current wettillg with a risk of :future settlement if the subsurface wetting continues. The ' drainage swale ~hOuld be sloped as steep as practical or lined with an impel."Vious membrane to limit surface water infiltration. Surface grates that connect to a solid drain pipe and a swale grade of5% are suggested fur the drainage improvements. Roof runoff needs to be piped to the swale or into a separate drainage pipe sloped. to daylight. •' . . ·Additional investigation of the water problem needs to be made at Lot 165 tci prevent leakage into the crawlspace. This could require video taping and/or excavating the roof · drain piping to verify it is water tight. Backfill sho~ld be compacted to at least 90% of standard Proctor density and should be, a clayey fine-graded soil that will limit moisture infiltration. Limitations: This study has been conducted in accordance with generally accepted geotechnical engineering principles and practices in this area at this time. We make no warranty either express or implied.

Sand and Silt (SM-ML); slightly sandy to very sandy, scattered gravel to gravelly zones, soft to medium stiff and moist to very moist to very stiff and slightly moist with depth, light brown. (Debris Fan Deposits) SAND (SM); silty, gravelly, loose to medium dense, very mois~ brown. (Debris fan Deposits). Gravel, Cobbles and Boulders (GM-GP); dense, slightly moist, broWn, rounded rock. (River Alluvium) Relatively undisturbed drive sample; 2-inch LD. California liner sample. Drive sample blow count; indicates that 9 blows of a 140 pound hammer falling 30 inches were required to drive the California sampler 12 inches. Caved depth following drilling. Practical drilling refusal in dense gravel alluvium. 1. Borings 1,2 and 3 were drilled on October 31, 2007, Boring 4 was drilled on November 26, 2007, and Boring 5 was drilled on December 12, 2007 with 4-inch diameter continuous flight power auger. 2. Locations of exploratory borings were measured approximately by pacing from features shown on the subdivision plat plan: · · 3. Elevations of exploratory borings were not measured and the Jogs of exploratory borings are drawn to depth. 4. The exploratory boring locations and elevations should be conside(ed accurate only to the degree implied by the method used. 5. The lines betweeri rriaterials shown on the exploratory boring logs represent the approximate boundaries between · material types and transitions may be gradual. 6. No free water was: encountered in the· borings at the time of drilling. Fluctuation in water level may occur With time. 7.
