The study was conducted in accordance with our agreement for geotechnical engineering services to Crawford Design Build, LLC dated May 7, 2007. The data obtained and our recommendations based on the proposed construction and subsurface conditions encountered are presented in this report. Proposed Construction: The proposed residence will be two story wood frame construction above a crawlspace with an attached garage. The site is shown on Figure I. Garage floor will be slab-on-grade. Cut depths are expected to range between about 2 to 4 feeL Foundation loadings for this type of construction are assumed to be relatively light and typical of the proposed type of construction. If building conditions or foundation loadings are significantly different from those described above, we should be notified to re-evaluate the recommendations presented in this report. Site Conditions: The site is located on Diamond A Ranch Road, bordered by the 18 1h tee box to the north and vacant of structures. Vegetation consists of grass and weeds. The ground surface is relatively flat with a slight slope down to the southwest. Parker 303-841-7119 • Color~ldo Springs 719-6:13-5562 •. Silverthorne 970-468-1989 -2- Subsidence Potential: The Aspen Glen Subdivision is underlain by Pennsylvania Age Eagle Valley Evaporite bedrock. The evaporite contains gypsum deposits. Dissolution of the gypsum under certain conditions can cause sinkholes to develop and can produce areas of localized subsidence. During previous studies in the area, several broad subsidence areas and smaller size sinkhole areas were observed scattered throughout the Aspen Glen development, predominantly on the east side of the Roaring Fork River (Chen-Northern, Inc., 1993). Lot F-18 is mapped as being on the western side of a broad depression. A sinkhole was mapped about I 00 feet east of the subject lot. Based on our present knowledge of the site, it cannot be said for certain that sinkholes will not develop. In our opinion, the risk of ground subsidence at Lot F-18 is low and similar to other lots in the area but the owner should be aware of the potential for sinkhole development. We have in the attached appendix the Chen-Northern recommendations for building in a broad surface impression area. We believe these recommendations are conservative but will reduce structural distress in the event of future ground movement and should be considered in the design. Subsurface Conditions: The subsurface conditions at the site were evaluated by excavating two exploratory pits at the approximate locations shown on Figure I. The Jogs of the pits are presented on Figure 2. The subsoils encountered, below about 6 inches of topsoil, consist of sandy silty clay to about 3 feet overlying silty sandy gravel with cobbles and small boulders. No free water was observed in the pits at the time of excavation and the soils were slightly moist to moist. Foundation Recommendations: Considering the subsoil conditions encountered in the exploratory pits and the nature of the proposed construction, we recommend spread footings placed on the undisturbed natural granular soil designed for an allowable soil bearing pressure of2,500 psf for support of the proposed residence. The upper sandy clay soils tend to compress after wetting and should be removed from beneath footing areas. Footings should be a minimum width of 16 inches for continuous walls and 2 feet for columns. Loose and disturbed soils encountered at the foundation bearing level within the excavation should be removed and the footing bearing level extended down to the undisturbed natural granular soils. Exterior footings should be provided with adequate JobNo.I070367 ~tech -3- cover above their bearing elevations for frost protection. Placement of footings at least 36 inches below the exterior grade is typically used in this area. Continuous foundation walls should be reinforced top and bottom to span local anomalies such as by assuming an unsupported length of at least I 0 feet. Foundation walls acting as retaining structures should be designed to resist a lateral earth pressure based on an equivalent fluid unit weight of at least 50 pcf for the on-site soil as backfill. Floor Slabs: The natural on-site soils, exclusive of topsoil, are suitable to support lightly loaded slab-on-grade construction. To reduce the effects of some differential movement, 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 less than 50% passing the No. 4 sieve and less than 2% passing the No. 200 sieve. 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 crawlspace areas, be protected from wetting and hydrostatic pressure buildup by an underdrain system. A shallow crawlspace (less than 3 feet) should not require an underdrain system provided the exterior backfill is properly placed and compacted. If drains are installed, they should consist of drainpipe placed in the bottom of the wall backfill surrounded above the invert level with free-draining granular material. The drain Job No.l07 0367 -4- should be placed at each level of excavation and at least 1 foot below lowest adjacent finish grade and sloped at a minimum 1% to a suitable gravity outlet, drywell 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 Yz feet deep. Surface Drainage: The following drainage precautions should be observed during construction and maintained at all times after the residence has been completed: 1) Inundation 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. Free-draining wall backfill should be capped with about 2 feet of the on-site, finer graded soils to reduce surface water infiltration. 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 6 inches in the first 10 feet in unpaved areas and a minimum slope of 3 inches in the first 1 0 feet in pavement and walkway areas. 4) Roof downspouts and drains should discharge well beyond the limits of all backfill. 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 and recommendations submitted in this report are based upon the data obtained from the exploratory pits excavated at the locations indicated on Figure I and to the depths shown on Figure 2, the proposed type of construction, and our experience in the area. Our services do not include determining the presence, prevention or possibility of mold or other biological contaminants (MOBC) JobNo.I070367 - 5 - developing in the future. If the client is concerned about MOBC, then a professional in this special field of practice should be consulted. Our findings include interpolation and extrapolation of the subsurface conditions identified at the exploratory pits and variations in the subsurface conditions may not become evident until excavation is performed. If conditions encountered during construction appear different from those described in this report, we should be notified at once so re-evaluation of the recommendations may be made. This report has been prepared for the exclusive use by our client for design purposes. We are not responsible for technical interpretations by others of our information. As the project evolves, we should provide continued consultation and field services during construction to review and monitor the implementation of our recommendations, and to verify that the recommendations have been appropriately interpreted. Significant design changes may require additional analysis or modifications to the recommendations presented herein. We recommend on-site observation of excavations and foundation bearing strata and testing of structural fill by a representative of the geotechnical engineer. If you have any questions or if we may be of further assistance, please let us know.

The grouting procedure should help reduce the settlement risk but not totally eliminate it. Therefore, we believe that avoiding the sinkholes by building setback is the lower risk and the more appropriate approach that should be taken. Development in Surface Depression Areas: Based on our findings, development within the ground surface depression areas (shown on Fig. I) should be feasible provided appropriate mitigative designs are implemented for the residential buildings, utilities and roadways as described below. The appropriate level of the mitigative designs depend on the potential ground deformation, the building type, location and configuration and level of tolerable maintenance (mainly for roadways and utilities). Building design considerations include use of a relatively rigid foundation, (such as a stiffened slab or raft) and a simply shaped building footprint to reduce potential damage in the event of differential movement. These design concepts would be included in the engineered foundations for residences located in the depression areas. Utilities should be designed and constructed to be relatively flexible and allow for differential movement without rupturing. Where possible, settlement sensitive main utility lines should be routed outside of the ground surface depression areas. Roadways can be conventionally designed and constructed with provisions for maintenance if subsidence related distress is experienced. There are several geotechnical design concepts which can be used to mitigate potential subsidence damage to residential buildings and underground utilities. Special mitigative designs for a specific lot should be developed by the owner's architect and structural engineer and should be based on the type of building proposed and the site specific foundation conditions. The following design concepts are presented to assist in evaluating design options prior to site ChenONorthem,lnc. • • • I • • • I I I I I I I I I I I 9 specific investigations for an individual building site. The concept for underground utilities should be incorporated into the utility design by the developer. Building Configurations: The extent of damage to a building subjected to the surface effects of subsidence may be reduced by implementing several architectural measures in the building design. These measures would include the following: * * * * * * * Relatively flexible structural systems such as wood frame construction, flexible exterior siding, and dry wall interior partitions are preferable to less flexible masonry structural system and exterior sidings. Interior non-bearing partitions resting on the floor slab should be provided with slip joints so that slab movements are not transmitted to the upper structure. The building should be a low structure preferably limited to one or two stories. The building should have relatively small plan dimensions of 60 feet or less. If this is not practical then the building should be divided into independent modules. The building configuration should be a simple rectangular configuration with straight foundation walls and a minimum of side projections from the main building. The ground floor should be on a single level rather than using a split level design. Basements are particularly susceptible to subsidence damage and are not recommended unless the entire foundation is at basement level and designed for lateral earth loading. Chen~Northem, Inc.

Typical shallow spread footings would be a relatively flexible system and a rigid system is preferable for the larger magnitude deformations. Foundation system considerations are outlined below: * A raft foundation system is the preferable system and should be designed according to the site specific soil bearing conditions. * * * * The bottom surface of the raft should be smooth and free of vertical projections. The raft should be separated from the bearing soils by placing the raft on a minimum 4-inch thick compacted, clean sand. A polyethylene sheet should be placed between the raft and the sand layer. The use of deep foundation walls should be minimized to the extent practical. The soil pressure equal to at least twice the "at rest" earth pressure (on the order of 80 to I 00 pcf equivalent fluid unit weight) should be assumed to act on all vertical surfaces in contact with the foundation soils. The bearing elevation of the raft should be placed below frost depth or sufficient soil cover should be provided for frost protection. Underground Utilities: Underground utilities are susceptible to the affects of area subsidence. As outlined below there are several mitigative design concepts which can be used to reduce the potential for damage. In our opinion the mitigation measures should be used where underground utilities are located in the ground surface depression areas shown on Fig 1. Chen ~Nonhem,lnc.

Positive restraints should be provided in pressure lines to prevent pipe separation. A flexible joint should be provided as close as practical to any building, manhole, or other rigid structural connection. A soil cushion in the immediate vicinity of the pipe should be provided by not over-compacting the backfill soils close to the pipe. Check valves should be placed at appropriate locations on all gas and water mains to permit interruption of flow in case of subsidence distress. DEBRlS FLOW RlSK AND MITIGATION Hazard Evaluation: This study shows that the alluvial and debris fans along the western side of the development are potential sites of water flooding and debris flows. The area evaluated is shown on the attached Fig IA. A summary of the basins and fans evaluated is presented on the attached Table IL The calculated flow depths and volumes are based on hydrological data provided by Schmueser Gordon Meyer, Inc. Potential water floods, with high sediment concentrations, should be considered for all of the basins upslope of the fans. Appropriate surface water hydrologic methods should be used to evaluate the flood hazards on all fans. Fans 1 and 2 in the southern part of the area are not subject to debris flows, but debris flows should be considered on Fans 3 through 25 and the area to the north (see Fig. !A). Based on numerical debris flow modeling, we have designated three potential hazard Chen ONorthem, Inc.
