The study was conducted in accordance with our agreement for geotechnical engineering services to David Johnston Architects dated June 26, 2001. 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 a one story wood frame structure over a crawlspace with an attached garage located on the site as shown on Fig. 1. The garage floor is proposed to be slab-on-grade. Cut depths are expected to range between about 3 to 5 feet. Foundation loadings are assumed to be relatively light and typical of the assumed type of construction. The septic disposal system is proposed to be located northwest of the proposed residence. 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 lot was vacant at the time of our field work and is located at the end of Wooden Deer Road. The building area is situated on a knoll at the west end of a west trending ridge and is relatively flat in the area of proposed construction. The ground surface slopes gently down from the proposed building site to the east. Steeper slopes exist down to the west and south. The lot is vegetated with pinon and sagebrush. Subsurface Conditions: The subsurface conditions at the site were evaluated by excavating two exploratory pits in the building area and one profile pit in the assumed septic disposal area at the approximate locations shown on Fig. 1. The logs of the pits are presented on Fig. 2 . The subsoils encountered, below up to about 11/i feet of topsoil, consist of relatively dense basalt cobbles and boulders in a sandy silt matrix . David Johnston, Architects July 13, 2001 Page2 Results of swell-consolidation testing performed on a relatively undisturbed sample of the sandy silt matrix, presented on Fig . 3, indicate low compressibility under existing moisture conditions and light loading and a low collapse potential (settlement under a constant load) when wetted. The sample showed moderate compressibility after wetting and increased loading . Results of a gradation analysis performed on a sample of silty sand with gravel and cobbles (minus 5 inch fraction) obtained from the site are presented on Fig. 4. 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 soil designed for an allowable soil bearing pressure of 2,000 psf for support of the proposed residence. The matrix soils tend to compress after wetting and there could be some post-construction foundation settlement. 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 soils . Excavation may be difficult due to the basalt boulders and may require special excavation techniques such as rock splitting or chipping . Voids created by removal of boulders should be backfilled with compacted road base or concrete. Exterior footings should be provided with adequate 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 12 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 devoid of oversized rock. An underdrain should not be needed provided that positive surface drainage as described below is maintained around the residence. Floor Slabs: The natural on-site soils, exclusive of topsoil, are suitable to support lightly loaded slab-on-grade construction. The matrix soils tend to compress after wetting and there could be some post-construction settlement. To reduce the effects of some differential movement, garage 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 floor 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. H-P GEOTECH David Johnston, Architects July 13, 2001 Page 3 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 or imported road base .devoid of vegetation, topsoil and oversized rock. 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. 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 pavement and walkway areas. 4) Roof downspouts and drains should discharge well beyond the limits of all backfill. 5) Landscaping which requires regular heavy irrigation should be located at least 5 feet from the building. Percolation Testing: Percolation tests were conducted on July 6, 2001 to evaluate the feasibility of an infiltration septic disposal system at the site. One profile pit and three percolation holes were dug at the locations shown on Fig. 1. 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 test boles are similar to those exposed in the Profile Pit shown on Fig. 2 and below about 1 foot of topsoil, consist of 2 1h feet of stiff silt and sand overlying dense basalt cobbles and boulders in a sandy silt matrix. Percolation test results indicate infiltration rates between 36 and 90 minutes per inch with an average of 57 minutes per inch. The percolation test results are presented in Tab.le Il .. Limitations: This study has been conducted in accordance with generally accepted geotecbnical engineering principles and .practices in this area at this time. We make no warranty either expressed 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 Fig. 1, the proposed type of construction, percolation test results and our experience in the area. Our findings include interpolation and extrapolation of the subsurface conditions identified at the exploratory pits and variations in the H-P GEOTECH David Johnston, Architects July 13, 2001 Page4 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 bas 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. Sincerely, HEPWORTH -PAWLAK GEOTECHNICAL, INC. Trevor L. Knell Reviewed by: Daniel E. Hardin, P.E.

C1296 ALL SERVICE septic , LLC performed a subsurface investigation and completed an onsite wastewater treatment system (OWTS) design for the subject residence . The 5.48-acre property is located outside of Carbondale , in an area where OWTSs are necessary . Legal Description : Lot 2, Wooden Deer Subdivision Parcel ID: 2393-243-04-002 SITE CONDITIONS The property is currently undeveloped. A 5-bedroom, single-family residence is proposed . The subdivision is served potable water from a community water system . A water tank that stores water for the entire subdivision is located on the property . The proposed soil treatment area (STA) must be located at least 100-feet from the water tank. Location of water lines was not provided on the site plan. All OWTS components must be located at least 25-feet from any water line, and if a sewer line crosses a water line , the sewer line must be encased within 10-feet of the crossing (see Encasement Detail W4.0/2). The proposed STA location has approximately a ten percent slope across the proposed STA to the west. There are no potential future land use changes or bedroom additions planned for the property. SUBSURFACE The subsurface was investigated on June 16 , 2017 by exploring the foundation excavation. A visual and tactile soil analysis was completed by Carla Ostberg at the time of excavation. 1 The materials encountered in the excavation consisted of topsoil to 6.0-inches, underlain by tan caliche to a maximum depth explored of 8.0-feet Large basalt boulders are present below 4-feet. No bedrock or groundwater was encountered . 1 Carla Ostberg holds a Certificate of Attendance and Examination from the CPOW Visual and Tactile Evaluation of Soils Training . Page 2 An additional test pit must be excavated in the proposed STA prior to construction of the OWTS. This office must be called to verify the soils. A tactile analysis of the soils was taken from the excavation at approximately 3-feet below grade. The soil formed a ball and a weak ribbon. Soil structure shape was blocky, soil structure grade was weak, and consistence was extremely firm to rigid. STA sizing is based on Soil Type 2A, Silt Loam with weak structure grade. A long term acceptance rate (LTAR) of 0.5 gallons per square foot will be used to design the OWTS, in accordance with Table 10-1 Soil Type 2A presented in the Garfield County On-Site Wastewater Treatment System Regulations, adopted April 14, 2014. 4 ~ Foundation excavation Sidewall (weak structure grade) DESIGN SPECIFICATIONS Design Calculations: Average Design Flow= 75 GPO x 2 people/bedroom x 3 bedrooms+ 150 GPO (4th and 5th bedrooms)= 600 GPO =600 GPO LTAR = 0.5 GPO/SF 600 GPO I 0.5 GPO/SF x 1.2 (gravity beds) x 0.7 (chambers)= 1008 SF Page 3 The new OWTS design is based on 5-bedrooms. An average daily wastewater flow of 600 GPD will be used. The system installation will include a new 1500-gallon, two-compartment concrete septic tank with an effluent filter installed on the outlet tee of the septic tank. The septic tank may not be buried more than 4-feet below grade and risers must bring the manhole lids to grade for access. Effluent will gravity flow to a distribution box, and then to three gravelless chamber beds. The distribution box must be accessible from grade and must have flow equalizers, or similar product, installed on each outlet pipe in the distribution box to assure equal flow to each bed. Each bed will consist of 3 rows of 10 'Quick 4' Infiltrator® Low Profile chambers connected with a level manifold, for a total area of 1080 square feet of infiltrative area. The infiltrative area may not exceed 4- feet below native grade. Inspection ports must be installed in each corner of each bed. Ports may be cut to grade and placed in sprinkler boxes for access. The component manufacturers are typical of applications used by contractors and engineers in this area. Alternatives may be considered or recommended by contacting our office. Construction must be according to Garfield County On-Site Wastewater Treatment System Regulations, the OWTS Permit provided by Garfield County Building Department, and this design. REVEGETATION REQUIREMENTS An adequate layer of good quality topsoil capable of supporting revegetation shall be placed over the entire disturbed area of the OWTS installation. A mixture of native grass seed that has good soil stabilizing characteristics (but without taproots), provides a maximum transpiration rate, and competes well with successional species. No trees or shrubs, or any vegetation requiring regular irritation shall be placed over the STA. Until vegetation is reestablished, erosion and sediment control measures shall be implemented and maintained on site. The owner of the OWTS shall be responsible for maintaining proper vegetation cover. OPERATION INFORMATION AND MAINTENANCE The property owner shall be responsible for the operation and maintenance of each OWTS servicing the property. The property owner is responsible for maintaining service contracts for manufactured units, alternating STAs, and any other components needing maintenance. Geo~fabrics or plastics should not be used over the STA. No heavy equipment, machinery, or materials should be placed on backfilled ST As. Livestock should not graze on the ST A. Plumbing fixtures should be checked to ensure that no additional water is being discharged to OWTS. For example, a running toilet or leaky faucet can discharge hundreds of gallons of water a day and harm a ST A. If an effluent filter or screen has been installed in the OWTS, we recommend this filter or screen be cleaned annually, or as needed. If the OWTS consists of a pressurized pump system, we recommend the laterals be flushed annually, or as needed. The homeowner should pump the septic tank every two years, or as needed gauged by measurement of solids in the tank. Garbage disposal use should be minimized, and non-biodegradable materials should not be placed into the OWTS. Grease should not be placed in household drains. Loading from a water softener should not be discharged into the OWTS. No hazardous wastes should be directed into the OWTS. Mechanical room drains should not discharge into the OWTS. The OWTS is engineered for domestic waste only. Page 4 ADDITIONAL CONSTRUCTION NOTES If design includes a pump, weep holes must be installed to allow pump lines to drain to minimize risk ot freezing. The pump shall have an audible and visual alarm notification in the event of excessively high water conditions and shall be connected to a control breaker separate from the high water alarm breaker and from any other control system circuits. The pump system shall have a switch so the pump can be manually operated. Excavation equipment must not drive in excavation of the STA due to the potential to compact soil. Extensions should be placed on all septic tank components to allow access to them from existing grade. Backfill over the STA must be uniform and granular with no material greater than minus 3-inch. INSTALLATION OBSERVATIONS ALL SERVICE septic, LLC must view the OWTS during construction. The OWTS observation should be performed before backfill, after placement of OWTS components. Septic tanks, distribution devices, pumps, dosing siphons, and other plumbing, as applicable, must also be observed. ALL SERVICE septic, LLC should be notified 48 hours in advance to observe the installation. LIMITS: The design is based on information submitted. If soil conditions encountered are different from conditions described in report, ALL SERVICE septic, LLC should be notified. All OWTS construction must be according to the county regulations. Requirements not specified in this report must follow applicable county regulations. The contractor should have documented and demonstrated knowledge of the requirements and regulations of the county in which they are working. Licensing of Systems Contractors may be required by county regulation. Please call with questions.

To exercise its warranty rights, Holder must notify Infiltrator in writing at its Corporate Headquarters in Old Saybrook, Connecticut within fifteen (15) days of the alleged defect. Infiltrator will supply replacement Units for Units determined by Infiltrator to be covered by this Limited Warranty. Infiltrator's liability specifically excludes the cost of removal and/or installation of the Units. (b) THE LIMITED WARRAN1Y AND REMEDIES IN SUBPARAGRAPH (a) ARE EXCLUSIVE. THERE ARE NO OTHER WARRANTIES WITH RESPECT TO THE UNITS, INCLUDING NO IMPLIED WARRANTIES OF MERCHANTABILl1Y OR FITNESS FOR A PARTICULAR PURPOSE (c) This Limited Warranty shall be void if any part of the chamber system is manufactured by any- one other than Infiltrator. The Limited Warranty does not extend to incidental, consequential, spe- cial or indirect damages. Infiltrator shall not be liable for penalties or liquidated damages, including loss of production and profits, labor and materials, overhead costs, or other losses or expenses incurred by the Holder or any third party. Specifically excluded from Limited Warranty coverage are damage to the Units due to ordinary wear and tear, alteration, accident, misuse, abuse or neglect of the Units; the Units being subjected to vehicle traffic or other conditions which are not permitted by the installation instructions; failure to maintain the minimum ground covers set forth in the installation instructions; the placement of improper materials into the system containing the Units; failure of the Units or the septic system due to improper siting or improper sizing, excessive water usage, improper grease disposal, or improper operation; or any other event not caused by Infiltrator. This Limited Warranty shall be void if the Holder fails to comply with all of the terms set forth in this Limited Warranty. Further, in no event shall Infiltrator be responsible for any loss or damage to the Holder, the Units, or any third party resulting from installation or shipment, or from any product liability claims of Holder or any third party.
