Job No. 4 405 92 Dear Mr. Van Portfliet: As requested, we have conducted a subsoil study at the subject site. The study consisted of observing and sampling several backhoe pits in the proposed building areas, performing laboratory testing and providing a report summarizing the data and providing foundation design recommendations. Subsurface conditions encountered in the exploratory pits excavated in the proposed building areas cons ist of a variable depth of fine- grained silty clays, some of which is fill, underlain by relatively dense coarse gravel alluvium. Groundwater was not encountered in the pits at the time of observation. The proposed residence and barn should be founded on spread footings placed entirely on the underlying coarse gravel subsoils and designed for an allowable bearing pressure of 3000 psf. The report which follows describes our investigation, summarizes our findings, and presents our recommendations. It is important that we provide consultation during design, and field services during construction to review and monitor the implementation of the geotechnical recommendations. If you have any questions regarding this report, please contact us. Sincerely, C ORTHERN, INC. David A. Young . DAY /ec Rev.

The project site is shown on Fig. 1. The purpose of the study was to develop recommendations for the foundation design. The study was conducted in accordance with our agreement for geotechnical engineering services to Matt Van Portfliet, dated June 30, 1992. Subsequent to the agreement letter, Mr. Van Portfliet requested that we perform percolation testing at an additional cost of about $200. Chen - Northern previously evaluated the geologic hazards at the proposed subdivision, submitting our findings under Job No. 4 338 90 in 1990. A field exploration program consisting of observing several exploratory backhoe pits previously excavated at the site was done to obtain information on subsurface conditions. Samples obtained during the field exploration were tested in the laboratory to determine compressibility and other engineering characteristics of the on -site soils. 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 foundations. The results of the field exploration and laboratory testing are presented in the report. This report has been prepared to summarize the data obtained during this study and to present our conclusions and recommendations based on the proposed construction and the subsoil conditions encountered. Design parameters and a discussion of geotechnical engineering considerations related to construction of the proposed residence and barn are included in the report. Chen @Northern, Inc.oo s 2 PROPOSED CONSTRUCTION The locations of the proposed residence and barn are shown on Fig. 1. The residence will be a two -story wood frame structure. The lower level will be a garden level basement. The barn will be a two -story wood frame structure with the lower floor constructed near the existing ground surface. Ground floors will be a combination of structurally supported over crawl space in the residence and slab -on -grade and dirt in the barn. Grading for the construction is assumed to be relatively minor with cut depths between about 2 to 5 feet. A wood foundation system is proposed to support the buildings. We assume relatively light foundation loadings, typical of the proposed type of construction. A conventional leach field septic system located north of the barn is planned to dispose of on -site sewage. If building loadings, location or grading plans change significantly from those described above, we should be notified to reevaluate the recommendations contained in this report. SITE CONDITIONS The site is a vacant lot within the Teller Springs Subdivision. The ground surface slopes strongly down to the east from County Road 109 to the edge of a high bluff which then slopes very steeply down to the floodplain of the Roaring Fork River. There has been some fill placed on the lot, apparently due to utility relocation, along the west side of the building sites. Vegetation consists of scattered grass and weeds. There are several springs Chen @Northern, Inc. 3 at the base of the bluff about 30 feet in elevation below the building sites. Lot 14 is the only other lot currently developed in the subdivision. FIELD EXPLORATION The field exploration for the project was conducted on July 2, 1992: Six exploratory pits were excavated at the locations shown on Fig. 1 to evaluate subsurface conditions. The pits were dug with a rubber -tired backhoe by the client prior to our arrival on -site. The pits were logged by a representative of Chen - Northern, 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, Fig. 2. The samples were returned to our laboratory for review by the project engineer and testing. We returned to the site on July 10, 1992 to perform percolation testing to evaluate infiltration characteristics of the coarse granular soils. The percolation testing was done in hand dug pits in the bottom of about 3 -feet deep backhoe pits after soaking the previous day. Results of the percolation tests are provided in Table I. SUBSURFACE CONDITIONS The subsoil conditions encountered at the site are shown graphically on Fig. 2. The subsoils consist of a few inches of organic topsoil, and up to about 2 1/2 feet of man- placed fill overlying medium stiff, sandy clay -silt soils. At depths of 2 1/2 to greater than 4 feet in Chen @Northern, Inc. 4 - the pits, relatively dense, sandy gravel alluvium containing cobbles and boulders was encountered. Laboratory testing performed on samples obtained from the pits included natural moisture content and dry density and gradation analyses. Results of consolidation testing performed on a relatively undisturbed drive sample of the sandy clay -silt soils, presented on Fig. 4, indicate moderate to high compressibility under conditions of loading and wetting. Results of gradation analyses performed on a disturbed bulk sample (minus 5 -inch fraction) of the natural coarse granular soils are shown on Fig. 5. No free water was observed in the pits and the subsoils were slightly moist. DESIGN RECOMMENDATIONS FOUNDATIONS Considering the subsoil conditions encountered in the exploratory pits and the nature of the proposed construction, we recommend the buildings be founded with spread footings bearing on the natural coarse granular soils below all fill and fine- grained clay -silt soils. The design and construction criteria presented below should be observed for a spread footing foundation system. The construction criteria should be considered when preparing project documents. 1)Footings placed on the undisturbed natural coarse granular soils should be designed for an allowable soil bearing pressure of 3000 psf. Based on experience, we expect settlement of footings designed and constructed as discussed in this section will be about 1 inch or less. Chen @Northern,Inc.Eng. ,=a S: st 5 2)The footings should have a minimum width of 16 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)Continuous foundation walls should be reinforced to span local anomalies such as by assuming an unsupported length of at least 10 feet. Foundation walls acting as retaining structures should also be designed to resist a lateral earth pressure corresponding to an equivalent fluid unit weight of 40 pcf for an imported crushed rock backfill. 5)All existing fill, topsoil and any loose or disturbed soils should be removed and the footing bearing level extended down to relatively dense natural coarse granular soils. 6)A representative of the soil engineer should observe all footing excavations prior to concrete placement to evaluate bearing conditions. FLOOR SLABS The natural on -site soils, exclusive of topsoil, are suitable to support lightly loaded slab -on -grade construction. For slabs bearing on the compressible clay -silt soils, there is a risk of slab settlement and distress if these soils become wetted. 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 Chen @Northern, Inc. 6 based on experience and the intended slab use. A minimum 4 -inch layer of gravel can be placed beneath slabs to facilitate drainage and act as a leveling course. This material should consist of minus 2 -inch aggregate with less than 50% passing the No. 4 sieve and less than 12% 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 gravels devoid of vegetation, topsoil and oversized rock. Removal of the compressible clay -silt soils below slab areas and replacing with a granular fill material should reduce the risk of slab distress. SURFACE DRAINAGE A perimeter underdrain system around the residence basement level does not appear necessary with proper wall backfill and surface drainage. The following drainage precautions should be observed during construction and maintained at all times after the residence and barn have 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. 3)The ground surface surrounding the exterior of the buildings 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 Chen @Northern, Inc.Ming E and Sc on; st, 7 the first 10 feet in paved areas. Granular wall backfill should be capped with about 2 feet of the on -site fine - grained soils to reduce surface water infiltration. 4)Roof downspouts and drains should discharge well beyond the limits of all backfill. PERCOLATION TESTING Results of the percolation testing of the coarse gravel soils at the site indicate average infiltration rates ranging from about 5 minutes per inch to 20 minutes per inch. A profile pit near the percolation tests did not encounter bedrock or groundwater to a depth of 7 feet. We believe the coarse gravel soils extend a considerable depth below the site. Based on these considerations, it appears feasible for a conventional leach field disposal system based in the coarse gravels to dispose of septic water. We have not evaluated the possible effect of the septic water on the springs that underlie the site. Due to the variations of the percolation rates, we recommend the system be oversized and based on a percolation rate of 30 minutes per inch. LIMITATIONS This report has been prepared in accordance with generally accepted soil and foundation engineering practices in this area for use by the client for design purposes. The conclusions and recommendations submitted in this report are based upon the data obtained from the exploratory pits excavated at the locations indicated on Fig. 1 and the proposed type of construction. The nature and extent of subsurface variations across the site may not Chen @Northern, Inc. 8 become evident until excavation is performed. If during construction, fill, soil, rock or water conditions appear to be different from those described herein, this office should be advised at once so reevaluation of the recommendations may be made. We recommend on -site observation of excavations and foundation bearing strata and testing of structural fill by a representative of the soil engineer.

GARFIELD COUNTY BUILDING AND PLANNING December 14, 1993 RETURN RECEIPT CERTIFIED Matthew Van Portfliet 2074 County Road 109 Glenwood Springs, CO 81601 Dear Mr. Van Portfliet: After our discussion during the 12/13/93 Board of County Commissioners meeting, I felt it was important that we clarify this issue regarding your "caretaker's" house. Enclosed for your review are copies of your Certificate of Occupancy and the application of a building permit. It is apparent that the building department did not read my comments under special conditions, on the permit application. As you can see, under the section "special conditions ", it is noted that "this permit is approved as a Single Family dwelling, not as a guest house or a caretaker unit ". This comment was placed on the application by me, as a part of the Planning Department sign off on the permit. This is a sign off on the zoning requirements, which the Building Department does not have the authority to override. While the Certificate of Occupancy says caretaker, it was a matter of incorrectly noting that on the permit, when in fact the permit was approved from a zoning perspective as a single family dwelling. The classification on the Certificate of Occupancy was a scrivener's error, because there are no provisions for a "caretaker's apartment" in the County zoning resolution. It is still possible to permit the unit as a "guest house" under the present provisions of the zoning resolution. This would have to occur prior to the issuance of a building permit for your other planned residence. Or, as we discussed, you and /or the homeowner's association for the subdivision could ask for a zone district text amendment that would affect all property in the County zoned A/R/RD. If you have any additional questions, you may call or write to me at this office. Sincerely, Mark L. Bean, Director Building and Planning MLB /sa Enclosures 109 8TH STREET, SUITE 303 94 § - 8212/625 - 5571/285 GLENWOOD SPRINGS, COLORADO 81601 GARFIELII COUN'T'Y APPLICATION FOR BUILDING PERMIT 7PERMITNUMBER7so / nn n please print or type DATE 1 - VP.-- 1LISsessr,S Three! k TO BE FILLED OUT BY APPLICANT PLOT PLAN ADDRESS 7,074..
