Box 771865 Steamboat Springs, CO 80477 Job No. 95-2125 As requested, NWCC, Inc. (Northwest Colorado Consultants, Inc.) visited the project site on November 20, 1998 to inspect the on -site sewage disposal system addition being constructed for the Schmoyer Residence & Barn located in a parcel of land in the NE 1/4 of Section 20, Township 6 North, Range 84 West in Eagle County, Colorado. Northwest Colorado Consultants, Inc. previously designed the addition for the existing septic system for the residence and barn under this job number dated May 12, 1998. The system design incorporates infiltration chambers placed in the near surface overburden soils. At the time of our visit, the client had installed a 1,000 gallon septic tank approximately 35 feet west of the west side of the barn. The effluent inlet and outlet pipes to the tank were installed and were checked for minimum grade. A 4-inch wye tap was installed into the existing effluent line directly west of the tank. The inlet and outlet pipes consisted of 4-inch pvc pipe meeting ASTM 3034 SDR35 requirements and was checked for minimum grade. The addition to the existing absorption system was also in place. Field measurements of the system indicate that the required number of chambers had been installed in the configuration indicated in the design. All infiltrators were installed in the natural overburden soils between approximately 8 to 12 inches below the original ground surface. Measurements indicate that the new chamber run was also installed at least the required 9-foot minimum separation distance. The client indicated that the new chamber run was installed fairly level. We did not observe final grading of the surfaces of the absorption bed or the new piping. We advised the client that the system should be covered by at least 18-inches of topsoil and extreme care should be taken not to disturb or crush any portion of the system during backfilling. This includes properly bedding and shading all piping with suitable fine grained soils to prevent breakage by larger rock. The owner should be aware that some settlement of the fill placed over the surfaces of the system can be expected, (970) 879.7888 • Fax (970) 879-7891 2063 Snow Bowl Plaza, P.O. Box 775226 • Steamboat Springs, CO 80477 therefore, we recommend that the owner observe the area for fill settlement. If excessive differential settlement occurs with time, ponding of surface runoff may become a problem and additional fill or grading may be required to maintain positive drainage away from the system. All disturbed areas around the field should be heavily seeded to promote revegetation. It appeared that the addition to the existing system was constructed in general accordance with the plans and specifications. If you have any questions regarding this letter, our observations or recommendations or if we may be of further service, please contact this office. Sincerely, NORTHWEST COLORAD C., Harold N.

Geotechnical / Environmental Engineering - Materials Testing Subject: On -Site Sewage Disposal System Addition, Schmoyer Residence & Barn, A Tract in NE 1/4, Section 20, T6S, R84W, Eagle County, Colorado. / Ladies & Gentlemen: RECEIVED MAY 15 1998 EAGLE COUNTY OMMUNItY QWW&©PMENT May 12, 1998 Charlie & Norma Schmoyer c/o Montana Log Homes of Colorado P.O. Box 771865 Steamboat Springs, CO 80477 Job Number 95-2125 6010-j)- PhOUL� This report presents the results of a design addition to the existing on -site sewage disposal system for the Schmoyer Residence and Barn under construction within a tract of land located in the NE 1/4 of Section 20, T6S, R84W located in Eagle County, Colorado. The original septic system design was completed under this job number and dated January 22, 1996. Proposed Construction: As we understand it, the owner is finishing living space in the barn structure and the barn will be constructed with hW-tooms�<`-and 1 bathroom. No clothes washer or food preparation facilities are planned for the structure. Site Conditions: The project site is located approximately one-half mile north of County Road 41 in Eagle County, Colorado. The site of the proposed sewage disposal system addition is located within vacant land along the west side of the existing leach field. The site was generally vegetated with sparse grasses, sage brush and pinon trees. The site in the vicinity of the proposed septic system slopes gently down to the west on the order of 3 to 5 percent. Subsurface Conditions: To investigate the subsurface conditions at the site, a test pit was excavated in the vicinity of the septic site and percolation tests were completed in the upper 30 inches of overburden soil. The subsoil conditions in the test pit consist of natural sands overlying sandstone bedrock to the maximum depth explored, 6.5 feet. The natural sands were silty with sandstone gravels and cobbles, nonplastic, medium dense, fine to medium grained, slightly moist to dry and light brown in color. Sandstone bedrock was encountered beneath the sands at a depth of approximately 6 feet. The sandstone was silty, nonplastic, very hard, fine grained, dry and light brown in color. Free groundwater was not encountered in the test pit at the time of the investigation. (970) 879-7888 • Fax (970) 879.7891 2068 Snow Bowl Plaza, Box 775226 • Steamboat Springs, CO 80477 A The percolation tests completed by our firm indicate that the overburden sands exhibit an average percolation rate of 1alwmmrates> per inch in the vicinity of the existing septic system and proposed addition. System Design: The results of the field investigation and percolation testing indicate that the site is suitable for a conventional trench absorption system. The existing system consists of 1?.9minnf_ ltrator - y chambers placed in a serial configuration and the proposed addition will lengthen,, l�run�.,and, add;l addnalunrofchambers. ,to thefield. The system design is based on the residence and barn containing five bedrooms, a clotheswasher and a garbage disposal. Using these facts we have calculated a maximum peak effluent flow o - &9alYl s per day (gpd) for the system. An average percolation rate of 11 minutes per inch and a maximum loading rate oi?pgpdhft2 for the natural overburden soils was used to calculate t e required absorption area. Using these values we have calculated a total required absorption area of 938 P. _'btracting the existing field area leaves a deficiency aft I ambers required for the total system. A septic tank with a minimum capacity oA,`'N ga dons is also required for the barn residence. The septic system design is shown in Figures #1 and #2 and the design calculations and specifications are given in Appendices A and B, respectively. The procedures and design criteria used in this design were obtained from the EPA "Design Manual - On -site Wastewater Treatment and Disposal Systems", 1980, the Colorado Department of Health "Guidelines on Individual Sewage Disposal Systems", revised September, 1993 and the Eagle County Environmental Health Department guidelines. Please be advised that Colorado law requires that a permit must be obtained prior to the construction, alteration or use of an on -site sewage disposal system. Limitations: The sewage disposal system design presented is based on currently accepted design procedures and the proposed construction. If the proposed construction changes or if there are additions of new facilities to those currently planned or in use, the septic system design will also most likely change. It should also be noted that all on -site sewage disposal system require periodic maintenance. The failure of the owner to provide periodic inspection and maintenance of the system can be the major cause of system failure.

The Environmental Health Division discontinued percolation tests on November 15, 1995 and.final inspections on December 2, 1995 due to climatic conditions. ISDS permits are active for 120 days after the date of issue if no Building Permit has been issued for the same property. If a Building Permit has been issued for the same property the ISDS will expire at the same time as the building permit. If you still plan to apply for a Building Permit this year or in the early months of 1996 you will need to have a percolation test conducted before your Building Permit will be released. You will have to contact a Registered Professional Engineering(RPE) firm to conduct your percolation test. If you have had your permit issued and have not had your final inspection completed, but plan on constructing the system in the next few weeks, please give our office a call and we will evaluate your permit on a case by case situation.

Ladies & Gentlemen: This report presents the results of an on -site sewage disposal system design for the Schmoyer Residence under construction within a tract of land located in the NE 1/4 of Section 20, T6S, R84W located in Eagle County, Colorado. Northwest Colorado Consultants, In(F reviously presented a mounded septic design under this job number and dated September 29, 1995. A mounded septic system design was implemented because of a lack of suitable overburden soils over the underlying bedrock surface. An additional subsurface investigation at the site indicates that a suitable site for a conventional trench �.:.� absorption system exists several hundre_d_feet southwest of the home site. The results of the subsurface investigation and septic design are presented below. s , Proposed Construction: As we understand it, the residence to be constructed will have 3 bedrooms, a 9 v�l clothes washer and a garbage disposal when completed. Site Conditions: The project site is located approximately one-half mile north of County Road 41 in Eagle County, Colorado. The site of the proposed sewage disposal is located within vacant land approximately 300 feet southwest of the building site. The site was generally vegetated with sparse grasses, sage brush and pinon trees. The site in the vicinity of the proposed septic system slopes gently down to the west on the order of 3 to 5 percent. Subsurface Conditions: To investigate the subsurface conditions at the site, a test pit was excavated in the vicinity of the site and percolation tests were completed in the upper 30 inches of overburden soil. The subsoil conditions in the test pit consist of(natural sands overlying sandstone bedrock to the maximum depth explored, 4gJee4) The natural sands were silty with sandstone gravels and cobbles, nonplastic, medium dense, fine to medium grained, slightly moist to dry and light brown in color. Sandstone bedrock was encountered beneath the sands at a depth of approximately 6 feet.

Free groundwater was not encountered in the test pit at the time of the investigation. pe-rc The percolation tests completed by our firm indicate that the overburden sands exhibit an average I t percolation rate 11 ' utes per inch in the vicinity of the proposed septic system. 1. �, ...ter.,,.. System Design: The results of the field investigation and percolation testing indicate that the site is suitable for a conventional trench absorption system. We have incorporated infiltrator chambers 1p aced in a serial configuration in the system design to reduce the disturbance to the site and maximize the effectiveness of the system. The system design is based on the residence containing three bedrooms, a clotheswasher and a garbage disposal. Using these facts we have calculated a maximum peak effluent flow of 67LgaLlons Rgr (gpd) for the system. An average percolation rate of 11 minutes per inch and a maximum loading rate of 1.2 gpd/ft2 for the natural overburden soils was to calculate the required absorption area. Using these values we have calculated a minimum required absorption area of 562.5 ft2. A septic tank with a minimum capacity of 1,000 gallons is also required. The septic system design is shown in Figures #1 and #2 and the design calculations and specifications are given in Appendices A and B, respectively. The procedures and design criteria used in this design were obtained from the EPA "Design Manual - On -site Wastewater Treatment and Disposal Systems", 1980, the Colorado Department of Health "Guidelines on Individual Sewage Disposal Systems", revised September, 1993 and the Eagle County Environmental Health Department guidelines. Please be advised that Colorado law requires that a permit must be obtained prior to the construction, alteration or use of an on -site sewage disposal system. Limitations: The sewage disposal system design presented is based on currently accepted design procedures and the proposed construction. If the proposed construction changes or if there are additions of new facilities to those currently planned, the septic system design will also most likely change. It should also be noted that all on -site sewage disposal system require periodic maintenance. The failure of the owner to provide periodic inspection and maintenance of the system can be, the major cause of system failure.

Gentlemen: As requested, Northwest Colorado Consultants, Inc. is currently designing an on -site sewage disposal system for the Schmoyer Residence to be constructed within a tract of land located in the NE 1/4 of Section 20, T6N, R84W located in Eagle County, Colorado. Northwest Colorado Consultants, Inc. V/ previously conducted a subsoil investigation for the residence under this job number and dated April 17, r� 1995. The subsoil conditions at the site generally consisted of a thin layer of natural sands overlying sandstone bedrock. The overburden sands ranged in thickness from approximately 1 to 1.5 feet in thickness. Due to the shallow depth to bedrock, we recommend that the on -site sewage disposal system be constructed as a mounded absorption system utilizing a minimum of three (3) feet of imported sand and gravel fill under the absorption bed. We are currently proceeding with the design and accompanying report and expect to have the final report available within one week.

April 17,1995 Charlie & Norma Schmoyer 175 Henderson Road Stockholm, NJ 07460 Job Number 95-2125 Subject: Subsoil Investigation, Proposed Schmoyer Residence, A Tract of Land in Sec. 20, T6S, R84W, Eagle County, Colorado. Ladies & Gentlemen: This report presents the result of a subsoil investigation and geotechnical evaluation for the proposed Schmoyer residence to be constructed within a tract of land located in the NE 1/4 of Section 20, T6S, R84W in Eagle County, Colorado. The approximate location of the project site is shown on Figure #1. The scope of our work included obtaining data from a visual inspection of the site, the drilling of two test holes, the sampling of the probable foundation soils and the laboratory testing of the samples obtained. The contents of this report present recommendations for economically feasible and safe type foundations, as well as allowable soil pressures and other design and construction considerations that are advisable, but not necessarily routine to quality design and building practices. Proposed Construction: It is our understanding that the owner proposes to construct a two story log framed structure over a full depth walkout basement. The lower level of the structure will be constructed with a slab -on -grade floor system placed 6 to 8 feet below the existing ground surface. For design purposes, we have assumed that the building loads will be light to moderate, typical of residential construction. If loadings or conditions are significantly different from those above, we should be notified to reevaluate the recommendations in this report. Site Conditions: The project site is located approximately one-half mile north of County Road 41 in Eagle County, Colorado. At the time of this investigation the building site was vacant and sparsely vegetated with grasses, sage brush and pinon trees. It appears that the area has generally been used for agricultural purposes in the past. The topography of the building site is fairly consistent and generally slopes gently down to the west on the order of five percent. It appeared that a maximum elevation difference of approximately 2 feet exists across the proposed building site. Subsurface Conditions: To investigate the subsurface conditions at the site two (2) test holes were advanced on March 21, 1995 with a track -mounted drill rig. The approximate test hole locations are shown on Figure #2. The subsoils encountered were consistent and generally consisted of a thin layer of natural sands overlying natural sandstone bedrock that extended to the maximum depth investigated, 9 feet where rig refusal was encountered on highly cemented sandstone. Graphic logs of the exploratory test hole are presented in Figure #3'and the associated legend and notes are presented in Figure #4. Natural sands were encountered at the ground surface in both test holes and extended to depths of approximately 1 to 1.5 feet. The sands were silty with sandstone pieces, nonplastic, loose, fine grained, slightly moist and light brown in color. Natural sandstone bedrock was encountered beneath the sands in both test holes. The sandstone was silty, nonplastic, very hard, fine grained, well to highly cemented, fractured, dry and light brown in color. A sample of the sandstone classified as an SM soil in accordance with the Unified Soil Classification System. The laboratory test results are summarized in Table 1. Free ground water was not encountered in the test holes at the time of this investigation. It should be noted that groundwater conditions can be expected to fluctuate with changes in precipitation and runoff. Foundation Recommendations: Based on the soils encountered in the test holes, the results of the field and laboratory investigations and the proposed construction, we believe an economically feasible and safe type of foundation system is spread footings or individual pads with grade beams founded on the natural sandstone bedrock. Foundation movement should be within tolerable limits if the following design and construction precautions are observed. 1) The footings placed on the undisturbed, natural sandstone should be designed for an allowable soil bearing pressure of 5,000 psf. 2) All footings or pad sizes should be computed based on the above soil pressures and placed on the natural sandstone found beneath the topsoil. 3) Any topsoil or loose natural soils encountered within the foundation excavations, should be removed and the footings extended down to more competent natural soils prior to concrete placement. 4) All foundation walls should be designed and reinforced to span an unsupported distance of 10 feet or the length between pads, whichever is greater. Job No. 95-2125 Northwest Colorado Consultants, Inc. Page 2 le 5) Due to the very hard bedrock conditions encountered in the test holes difficult excavating conditions should be expected. Layers of highly cemented, unfractured sandstone which could require blasting or other rock breaking techniques may be encountered. 6) All footings or pads should be placed well enough below final backfill grades to protect them from frost heave. Forty eight (48) inches is typical for this location considering normal snow cover and other winter factors. 7) Based on experience, we estimate total settlement for footings and pads designed and constructed as discussed in this section will be approximately 1 inch. Additional bearing capacity values along with the associated settlements are presented in Figure #5. 8) We suggest a soils engineer be called to the site when the foundation excavation is near completion to identify the bearing soils and confirm the recommendations in this report. Floor Slabs: We understand that the proposed structure will be constructed with the lower level having a slab -on -grade floor system. The natural on -site soils and bedrock, exclusive of topsoil, are suitable to support lightly to moderately loaded slab -on -grade construction. Floor slabs should be provided with control joints to reduce damage due to shrinkage cracking, and the slabs should be adequately reinforced. We suggest that control joints be provided on the order of 12 feet on center. A minimum 6-inch layer of free draining gravel should be placed beneath floor slabs. This material should consist of aggregate with less than 10% passing the #200 sieve and more than 50% retained on the No. 4 sieve. The granular layer will help distribute floor slab loadings, ease construction, prevent capillary water rise and aid in drainage. Fill placed beneath floor slabs should be a nonexpansive, granular material approved by the soil engineer. Fill should be placed and compacted to at least 95% of the maximum standard Proctor density within 2% of optimum moisture content. The on -site sands encountered at the site are suitable for use in compacted fills beneath floor slabs. However, due to the dry condition of the materials, additional moisture may be required to attain adequate compaction with the on -site materials. Underdrain System: The lower level of the structure should be protected by an underdrain system to help reduce the problems associated with surface drainage during high runoff periods. Localized perched water or runoff can infiltrate the foundation at the footing levels. This water can be one of the primary causes of differential foundation and slab movement. The drain should be located around the entire perimeter of the building and should be located between the top and bottom of footings. We recommend the use of perforated PVC pipe for the drain tile, which meets ASTM D-2729 requirements, to minimize the potential for crushing the pipe during backfill operations. The drain tile should be surrounded by at least 6 inches of free draining gravel. Job No. 95-2125 Northwest Colorado Consultants, Inc. Page 3 P, The holes in the drain tile should be oriented down between 4 o'clock and 8 o'clock to promote rapid runoff of the water. The drain tile system should be protected from contamination by a filter covering of Mirafi 14ON subsurface drainage fabric or an equivalent product. The drain should have a minimum slope of 1/8 inch per foot and should be daylighted at a positive outfall protected from freezing, or be led to a sump from which the water can be pumped. Caution should be taken when backfilling so as not to damage or disturb the installed underdrain. We recommend the drainage system include at least one cleanout, be protected against intrusion by animals at the outfall and be tested prior to backfilling. A typical perimeter/underdrain detail is shown in Figure #6. Foundation and Retaining Walls: Foundation walls and retaining structures which are laterally supported and can be expected to undergo only a moderate amount of deflection may be designed for a lateral earth pressure computed on the basis of an equivalent fluid unit weight of 45 pcf for the on -site granular materials. Cantilevered retaining structures on the site can be expected to deflect sufficiently to mobilize the full active earth pressure condition. Therefore, cantilevered structures may be designed for a lateral earth pressure computed on the basis of an equivalent fluid unit weight of 35 pcf for the on -site granular materials. All foundation and retaining structures should be designed for appropriate hydrostatic and surcharge pressures such as adjacent buildings, traffic and construction materials. An upward sloping backfill also increases the earth pressures on foundation walls and retaining structures. The lateral resistance of retaining wall foundations placed on undisturbed natural soils and/or properly compacted fill material at the site will be a combination of the sliding resistance of the footing on the foundation materials and the passive pressure against the side of the footing. Sliding friction can be taken as 0.4 times the vertical dead load. Passive pressure against the sides of the footing can be calculated using an equivalent fluid pressure of 275 pcf. We recommend the use of imported granular backfill for use Backfill should be carefully placed in uniform lifts and compacted to between 90 and 95 percent of the maximum standard Proctor density, near the optimum moisture content. Care should be taken not to overcompact the backfill since this could cause excessive lateral pressure on the walls. Some settlement of deep foundation wall backfill materials will occur even if the material is placed correctly. Compacted fill placed against the sides of the footings to resist lateral loads should be a non expansive material approved by the soil engineer. Fill should be compacted to at least 95% of the maximum standard Proctor density, near the optimum moisture content. Surface Drainaee: Proper surface drainage at this site is of paramount importance for minimizing the infiltration of surface drainage into the wall backfill and bearing soils which could result in increased wall pressures, differential foundation and slab movement. The following drainage precautions should be observed during construction and at all times after the building has been completed: Job No. 95-2125 Northwest Colorado Consultants, Inc. Page 4 0, 1) The ground surface surrounding the building should be sloped (minimum of 1.0 inch per foot) to drain away from the building in all directions to a minimum of 10 feet. Ponding must be avoided. If necessary, raising the top of foundation walls to achieve a better surface grade is advisable. 2) Non structural backfill around the building should be compacted to at least 90% of the maximum standard Proctor density at or near the optimum moisture content, as determined by ASTM D-698, in order to minimize future settlement of the fill. The backfill should be placed immediately after the braced foundation walls are able to structurally support the fill. Puddling or sluicing must be avoided. 3) The top 2 feet of soil within 10 feet of the foundation should be impervious in nature to minimize infiltration of surface water into the wall backfill. 4) Roof downspouts and drains should discharge well beyond the limits of all backfill. Roof overhangs which project two to three feet beyond the foundation should be considered if gutters are not used. 5) Landscaping which requires excessive watering and lawn sprinkler heads, should be located a minimum of 10 feet from the foundation walls of the building. 6) Plastic membranes should not be used to cover the ground surface adjacent to foundation walls. Limitations: The recommendations given in this report are based on the soils exposed at this site and the behavior of structures at neighboring, similar sites. We believe that this information gives a high degree of reliability for anticipating the behavior of the proposed structure; however, our recommendations are professional opinions and cannot control nature, nor can they assure the soils profiles beneath those or adjacent to those observed; therefore, no warranties of the accuracy of these recommendations beyond the limits of the obtained data is herein expressed or implied. This report is based on the investigation at the described site and on the specific anticipated construction as stated herein. If either of these conditions are changed, the results would also most likely change. Man-made or natural changes in the conditions of a property can also occur over a period of time. In addition, changes in requirements due to state of the art knowledge and/or legislation, do from time to time occur. As a result, the findings of this report may become invalid due to these changes. Therefore, this report is subject to review and not considered valid after a period of 3 years or if conditions as stated above are altered. It is the responsibility of the owner or his representative to insure that the information in this report is incorporated into the plans and/or specifications and construction of the project. It is advisable that a contractor familiar with construction details typically used for the local subsoils and climatic conditions Job No. 95-2125 Northwest Colorado Consultants, Inc.
