The project site is shown on Figure l. The purpose of the study was to evaluate the geologic and subsurface conditions and their impact on the project. The study was conducted in accordance with our proposal for geotechnical engineering services to Mamm Creek Commons, LLC, dated November 20, 2003. A field exploration program consisting of a geologic reconnaissance and excavation of exploratory pits was conducted on February 17 and 18, 2004 to obtain infonnation on the site and subsurface conditions. Samples of the subsoils and bedrock obtained during the field exploration were tested in the laboratory to detennine their classification, compressibility or swell and other engineering characteristics. The results of the field exploration and laboratory testing were analyzed to develop recommendations for project planning and preliminary design. We have also reviewed pnblished geologic literature and previous geologic mapping in the area. This report summarizes the data obtained during this study and presents our conclusions and recommendations based on the proposed development and subsurface conditions encountered. PROPOSED DEVELOPMENT The proposed Mamm Creek Subdivision consists of24 single family residential lots on about 47 acres as shown on Figure 1. The subdivision will be serviced by a private water system and central storage tank. Infiltration septic disposal systems are proposed at the individual home sites. If infiltration systems are not feasible on some of the lots, a combined septic disposal system may be considered. Access from the county road to the home sites will generally be by common driveways. lr-1~ Nn 104 150 ~tech -. -2- If development plans change significantly Jimn those described, we should be notified to re-evaluate the recommendations presented in this report. SITE CONDITIONS The proposed Mamm Creek Commons subdivision is located in the southwest Y. of Section 23 and the northwest '14 of section 26, T6S, R93W about one mile south of the Garfield County Airport in Garfield County, Colorado. Lots 1-12 are proposed to be located along the north and south sides of Grass Mesa Road near the intersection with County Road 319. The terrain north of Grass Mesa Road (Lots 1-8) is gently sloping down to the southeast from the base of steep cliffs located north of the project site. The slopes on the north side of Grass Mesa Road range from about 10% in the northeast part of the property to about 40% in the northwest part of the prope1iy. The ten-ain south of Grass Mesa Road (Lots 9 -12) is steeper with slopes up to 50%. The valley bottom on the north side of Grass Mesa Road is vegetated with native grass and weeds and the hillsides on the south side of Grass Mesa Road are heavily vegetated with pinon pine and scattered brush. Drainages run northeast and southeast through the project site into the main drainage adjacent to Grass Mesa Road. The main drainage runs northeast into Dry Creek. The drainages in the project area are ephemeral and only have surface flow during periods of intense precipitation. Wasatch Formation sandstone crops out on the cliffs to the north of the site as well as on the hillside to the south. Rough graded roads access most of the proposed home sites and preliminary site grading and utility installation are in progress. Lots 13-24 are proposed to be located on a bluff to the south of Grass Mesa Road and to tl1e west of County Road 319. The terrain in this development area is generally steep and irregular. Maximum slopes in tl1e southern part of the prope1iy are greater than J 00% above proposed Lot 24 in the southeast partofthe prope1iy where Wasatch Formation sandstone crops out along the rim of the bluff. The slopes on the proposed building sites range from about J 0% on proposed Lot 23 to about 40% on proposed Lots 17 and J 8. A , ,_.,_,_ lf\;11'\(1 ~tech -' 0 -.') - rough graded road currently accesses several of the home sites from County Road 319. Drainage in the project area is generally down to the northeast and no1thwest. The drainages are ephemeral and their chmmels are poorly defined. These ephemeral chmmels only have surface flow associated with heavy thunderstorm precipitation. Elevations on the property range from a maximum of about 5880 feet in the southwest part of the project area to about 5630 feet in the northeast part of the project area. The overall drainage from the project area is down to the northeast into Dry Creek. GEOLOGIC SETTING The project area is located on the eastern side of the Piceance Basin about six miles south of the Grand Hogback Monocline that defines the bounda1y between the Piceance Basin and the White River Uplift to the northeast. These regional geologic structures were formed during the Laramide Orogeny about 40 to 70 million years ago. The project area is underlain by the Paleocene-age Wasatch Formation (Shroba and Others, 1994). The strike of sedime,ntary bedding in this part of the Picem1ce Basin varies and dips are generally less than 10° NW. Surficial deposits aloqg the Colorado River valley near the project area include alluvial fans, slopewash deposits and debris flow deposits near drainages and along lower valley sides and colluvium below steeper valley sides. Landslides are locally present on steep mesa flanks in the region, but have not been mapped in close proximity to the project area (Shroba and Others, 1994). Major faults have not been mapped near the property (Shroba and Others, 1994 ). The closest fault zones to the project area with known or suspected post-glacial activity, movement within about the past 15,000 years, are the Williams Fork Mountain fault zone located about 80 miles to the northeast and the southern section of the Sa watch fault zone located about 95 miles to the southeast (Widmmm and Others, 1998). Job No. 104 !50 G~ech ~· . -4- SITE GEOLOGY Surficial soil deposits in the project area (shown on Figure 1) consist of stream chmmel alluvium, terrace alluvium, alluvial aprons, alluvial fans and colluvium overlying Wasatch Formation bedrock. STREAM CHANNEL ALLUVIUM Stream channel alluvium (Qal-1) is present in creeks and drainages in the northem patt of the project area. Stream cham1el alluvium locally consists of slightly bouldery, cobble to pebble gravel in a clayey sand matrix and may be up to 3 feet deep in stream beds. Cobbles and boulders in the alluvium are subangular to subrounded Wasatch Formation derived Satldstone and basalt derived from Miocene basalt flows located on mesas to the south and west. TERRACE ALLUVIUM Terrace alluvium (Qal-2) is present throughout the no1ihern and southeastern parts of the project area and may be up to 20 feet thick in these areas. The terrace alluvium consists of slightly bouldery, slightly cobbly sandy clay to clayey sand. Cobbles and boulders in the terrace alluvium are mainly subrounded Miocene basalt and Wasatch Formation derived sandstone and are up to 2.5 feet in diameter. These deposits are moistllre sensitive atld samples from these areas showed compression upon wetting in laboratory tests. ALLUVIAL APRONS Alluvial aprons (Qaa) are present below outcrops and at the mouths of ephemeral drainages tlu·oughout the project area. The alluvial aprons may be up to 15 feet thick in some parts of the project area. Materials in these deposits consist of poorly sorted clast- and matrix-supported, slightly bouldery, cobbly pebble gravel in a sandy clay to clayey sand matrix. Clasts are mainly angular to subangular Wasatch Formation derived 1~1~ 'l\.ln 10tl1')0 ~tech - 5 - sandstone. Alluvial apron materials are moisture sensitive tlu·oughout the project area. Laboratory testing of alluvial apron samples showed some areas to have hydrocompressive soils while other samples tested were expansive when wetted. ALLUVIAL FANS A relatively young alluvial fan (Qaf) is present near proposed Lots 14 and 15 in the southeast part of the project area. The alluvial fan materials consist of slightly bouldery, slightly cobbly, sandy clay to clayey sand and may be up to 15 feet thick. Laboratory testing of samples taken in this area showed the subsoils to have hydrocompressive potential. COLLUVIUM Colluvium (Qc) is present on hillsides throughout the project area and varies in thickness. The colluvium in the project area consists mainly of ru1gular to subangular cobbles and boulders in a sandy clay matrix. The cobbles and boulders in the colluvium are derived from Wasatch Formation bedrock and are sandstone, siltstone and claystone. Samples of colluvium tested in the laboratory were expansive when wetted. WASATCH FORMATION The Wasatch Fmmation (Tw) consists of interbedded and lenticular tan, yellowish to reddish brown, and reddish purple claystone, siltstone, sandstone and conglomerate that unconformably overlie the Upper Cretaceous age Mesa Verde Group. The Wasatch Formation was deposited in non-marine lacustrine, flood-plain, and high energy fluvial envirmm1ents. Highly weathered Wasatch Fonnation bedrock can produce expansive clay soils. .lob No. 104 150 C"~tech -6 - FIELD EXPLORATION The field exploration for the project was conducted on February 17, 2004. Twelve exploratory pits were excavated at the locations shown on Figure 1 to evaluate the subsurface conditions. 1l1e pits were dug with a CASE 888 trackhoe. The pits were logged by a representative of Hepworth-Pawlak Geotechnical, Inc. Samples of the subsoils were taken with relatively undisturbed and disturbed sampling methods. Depths at which the samples were taken are shown on the Logs of Exploratory Pits, Figure 2. The samples were returned to our laboratory for review by the project engineer and testing. Radiometric readings were also taken at each pit location in order to determine the gamma radiation level throughout the site. SUBSURFACE CONDITIONS Graphic logs of the subsurface conditions encountered at the site are shown on Figure 2. The subsoils in the lower elevation areas of the project site generally consist of about 1 foot of topsoil overlying sandy, slightly silty clay alluvium with occasional cobbles and boulders. The subsoils encountered at higher elevations of the project site consist of6 inches to 1 foot of topsoil overlying medium hard Wasatch Formation claystone and sandstone bedrock. Digging in the bedrock was difficult due to its hardness and practical bacld1oe refusal resulted after relatively shallow depth into the rock. Laboratory testing performed on samples obtained from the pits included natural moisture content and density, finer than sand size gradation analyses and liquid and plastic limits. The results of swell-consolidation testing performed on relatively undist<Jrbed samples, presented on Figures 4 to 8, typically indicate the silty clay soils encountered in the lower lying areas of the project site are compressible under conditions of loading and wetting. Testing of the colluvial clay soils and weathered claystone encountered in the higher Job No. 104 150 ~tech -., .-·· -7- southern elevation area of the project site typically showed a low to moderate expansion potential when wened. The laboratory testing is summarized in Table 1. No free water was encountered in the pits at the time of excavation. The subsoils were slightly moist to moist and the bedrock was slightly moist. GEOLOGIC ASSESSMENT Geologic conditions that should be considered in project plmming and design include potential flooding, moisture sensitive soils, construction related slope instability, rockfall hazards, radiation and earthquakes. FLASH FLOODING Several relatively large drainage basins are tributary to the project site and have ephemeral channels (Qal-1) that run tlu·ough the property. These chmmels are the potential site of high sediment concentration flash floods associated with runoff from unusually intense thunderstorms. The drainage design for the subdivision should include evaluation of the ephemeral cham1els on the site to determine if they have the capacity to convey the appropriate design runoff and if the chmmel will be stable during the design runoff. Without long-tenn observations, that are not available, it is not possible to estimate statistical recunence probabilities for thunderstorm related flash flood at the project site with a high level of confidence. In our opinion, the infrequent flash flood risk for the project cm1 be evaluated by sediment bulking for the 1 00-year design thunderstorm hydro graphs for the large drainage basins upslope of the project area. Design sediment bulking factors should be based on drainage basin specific evaluations. Runoff curve numbers typically used in estimating direct runoff for the 24-hour general storm are not appropriate for estimating design thunderstorm runoff. Guidance in selecting appropriate direct runoff curve numbers for design thunderstorms can be found in USBR (1977). Job No. 104150 --- -8 - ALLUVIAL FAN FLOODING The alluvial fan located below ephemeral drainages in the southeastern part of the project area near Lots 14 and 15 could be a potential source of flash flooding. Alluvial fans t)1)ically have poorly defined drainage channels and are subject to flash flooding during periods of intense thunderstorm activity. The potential for flash flood impacts to Lots 14 and 15 near ephemeral drainages should be evaluated as part of the drainage design for the subdivision. MOISTURE SENSITIVE SOILS Results from laboratory testing of samples taken at the site indicate that the clayey alluvial soils found at lower elevations throughout the project area are hydrocompressive. The laboratory test results also indicate that colluvial clay soils and weathered claystone at higher elevations in the project area are expansive when wetted. Hydrocompressive soils and expansive soils, when dry, provide acceptable foundation support. However, post-construction wetting ofhydrocompressive soils can result in relatively large differential settlement and similar wetting of expansive soils can result in relatively large differential heaving. Site specific soil and foundation studies on proposed lots will be needed to evaluate the hydrocompressive or expansive potential of the foundation soils and to develop appropriate foundation designs. Preliminary foundation design recommendations are presented in the Preliminary Design Recommendations section of this report. CONSTRUCTION RELATED SLOPE INSTABILITY We do not anticipate construction related slope instability problems at the project site for grading typically associated with residential construction of the type proposed. When building sites have been determined, it is recommended that the home owners have a Job No. 104 150 c~tech -9 - geoteclmical engineer evaluate the proposed grading and develop appropriate design criteria. ROCKFALL Wasatch Formation outcrops on the eastern side of the project area are a potential source of rockfall that could reach Lot 24. The apparent runout limit of rockfall extends into the no1thern part of the lot. It is our opinion that the likelihood that a rockfall will actually encounter a proposed residence on Lot 24 during a reasonable service life for a residential structure is low, but the Jot should not be considered risk free. If a rockfall were to hit a residential building it would likely result in severe damage and could ham1 the building's occupants. The prospective home owner should be informed of this condition and if this level of risk is not viewed as acceptable then further investigation and mitigation should be considered. Types of mitigation commonly used in rockfall areas consist of avoiding the hazard, catching structures located uphill of the home site, rock bolting and scaling or removal of overhanging rock outcrops above the site. GAMMA RADIATION The project site is not located on geologic deposits that would be expected to have high concentration of radioactive minerals. Gamma radiation readings of between 0.01 and 0.03 millirems per hour taken at the exploratory pit locations (shown on Figure 1) showed that near surface radiation levels throughout the project area are at or below average background levels for the region. However, there is a potential that radon gas could be present in the area. It is difficult to assess future radon gas concentrations in buildings before the buildings are constructed. Testing for radon gas levels could be done when the residences and other occupied structures have been completed. New buildings are often designed with provisions for ventilation of! ower enclosed qreas should post construction testing show unacceptable radon gas concentration. Job No. 10•1 150 ~ech -10- EARTHQUAKE CONSIDERATIONS The project area could experience earthquake related ground shaking. Historic earthquake ground shaking in the region has been moderately strong, but has not exceeded Modified Mercalli Intensity VI (Kirkham and Rogers, 1985). Modified Mercalli Intensity VI ground shaking should be expected during a reasonable exposure time for the proposed structures, but the probability for stronger ground shaking is low. Intensity \IJ ground shaking is felt by most people and causes general alann, but results in negligible damage to structures of good design and construction. Occupied structures should be designed to withstand moderately strong ground shaking with little or no damage and not to collapse under stronger ground shaking. The region is in the 1997 Unifom1 Building Code, Seismic Risk Zone 1. Based on our current understanding ofthe ea1ihquake potential in this part of Colorado, we see no reason to increase the previously accepted seismic risk zone for the region. PRELIMINARY DESIGN RECOMMENDATIONS The conclusions and recommendations presented below are based on the proposed development, subsurface conditions encountered in the exploratory pits, and our experience in the area. The rec01mnendations are suitable for planning and preliminary design but site specific studies should be conducted by the individual lot owners for their development. FOUNDATIONS Bearing conditions will vary depending on the specific location of the building on the property. Based on the nature of the proposed construction, spread footings bearing on the natural subsoils should typically be suitable at the building sites. We expect the footings can be sized for an allowable bearing pressure in the range of 1 000 psf co 2000 psf on clay subsoils in the lower elevations of the project area. Allowable bearing pressures on bedrock at higher elevations should be in the range of 3000 psf to 4000 psf. lohNo. 104150 ~tech -11 - Expansive clays and weathered claystone encountered in building areas may need to be removed or the footings designed to impose a minimum dead load pressure to limit potential heave. Foundation walls should be designed to span local anomalies and to resist lateral earth loadings when acting as retaining stmctures. Below grade areas and retaining walls should be protected from wetting and hydrostatic loading by use of an underdrain system. The footings should have a minimum depth of 36 inches for frost protection. FLOOR SLABS Slab-on-grade construction should be feasible for bearing on the natural soils or bedrock with low to no expansion potential when wetted. There could be some post construction slab movement at sites with collapsible or expansive soils and claystone. To reduce the effects of some differential movement, floor slabs should be separated from all bearing walls and colunms with expansion joints. Floor slab control joints should be used to reduce damage due to shrinkage cracking. A minimmn 4 inch thick layer offree-draining gravel should underlie basement level slabs to facilitate drainage. The expansion potential of the subsoils should be evaluated as part of the site specific geotechnical study for the residence design. UNDERDRAIN SYSTEM Although free water was not encountered in the exploratory pits, it has been our experience where there are clay soils and shallow bedrock that local perched groundwater can develop during times of heavy precipitation or seasonal runoff. An underdrain system should be provided to protect below-grade construction, such as retaining walls and basement areas from wetting and hydrostatic presswe buildup. The drains should consist of drainpipe surrounded above the inve1i level with free-draining granular material. The drain 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. lnh Nn. 1 04 150 c:;4;'J)tech -12- SlTE GRADING The risk of construction-induced slope instability at the site appears l0\7v. provided the buildings are located in the less steep parts of the property as planned and cut and fill depths are limited. Cut depths for the building pads and driveway access should not exceed about 10 feet. Fills should be limited to about 10 feet deep, especially where they encroach steep downhill sloping areas. Structural fills should be compacted to at least 95% of the maximum standard Proctor density at near optimum moisture content. Prior to fill placement, the subgrade should be carefully prepared by removing all vegetation and topsoil. The fill should be benched into the portions of the hillside exceeding 20% grade. The on-site soils excluding oversized rock and topsoil should be suitable for use in embankment fills. Pe1manent ulJJ'etained cut and fill slopes in clay soils should be graded at 2 horizontal to 1 vertical or flatter and protected against erosion by revegetation, rock riprap or other means. Oversized rock should be excluded from embankment fills. Steeper cut slopes may be feasible in bedrock, but this condition will need to be evaluated on a site specific basis. This ofiice should review site grading plans for the subdivision development prior to construction. SURFACE DRAINAGE The grading plan for the subdivision should consider runoff from steep uphill slopes, and drainages tlu·ough tl1e project and at individual sites. Water should not be allowed to pond which could impact slope stability and foundations. To limit infiltration into the bearing soils next to buildings, exterior backfill should be well compacted and have a positive slope away from the building for a distance of at least 10 feet. Roof downspouts and drains should discharge \Nell beyond the limits of all backfill and landscape irrigation should be restricted. ~tech --~-· -13- PER COLA T!ON TESTING Percolation tests were conducted on February !8 and !9, 2004 to evaluate the feasibility of infiltration septic disposal systems in the project area. One percolation hole was dug at each of the exploratory pit locations shown on Figure I. The test holes (nominal 12 inch diameter by 12 inch deep) were hand dug at the bottom of shallow backhoe pits and were soaked with water one day prior to testing. The soils exposed in the percolation holes are similar to those exposed in the exploratory pits shown on Figure 2 and typically consist of sandy silty clay with occasional cobbles at lower elevations of the project and weathered bedrock and sandy clay colluvium at higher elevations. The percolation test results are presented in Table 2. Based on the subsurface conditions encountered and the percolation test results, the lower elevation areas of the development (Lots 1-8) should be suitable for conventional infiltration septic disposal systems. The remaining lots located in higher elevation areas of the development area may require mounded or other engineered septic disposal systems due to the shallow bedrock and poor percolation soil conditions. Site specific percolation testing will be needed for the individual lot development. A civil engineer should design the infiltration septic disposal systems. LIMITATIONS This study has been conducted according to 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 repmt are based upon the data obtained from the field recmmaissance, review of published geologic reports, the exploratory pits located as shown on Figure 1, 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 (MOB C) developing in the future. .lob No. 104 150 ~ech -14- 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 so that re-evaluation of the recommendations may be made. This repmi has been prepared for the exclusive use by our client for plmming and preliminary design purposes. We are not responsible for teclmical interpretations by others of our infmmation. As the project evolves, we should provide continued consultation, conduct additional evaluations and review and monitor the implementation of our recommendations. 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 geoteclmical engineer.
