The 1.53-acre property is located outside of Glenwood Springs, in an area where OWTSs are necessary. Legal Summary: Section: 1 Township: 7 Range: 89 Subdivision: WESTBANK RANCH PUD #4 RESUB Lot: 6 Parcel ID: 2395-013-06-006 SITE CONDITIONS A 3-bedroom, single-family residence presently exists and is utilizing an existing OWTS. The existing OWTS consists of a 1250-gallon, two-compartment Norwesco® poly septic tank followed a soil treatment area (STA) comprised of 690 square feet of gravelless chamber trenches. The configuration and total number of chambers is unclear from the documents available to us. The system is documented by Garfield County Individual Sewage Disposal System (ISDS) Permit No. 2388 (enclosed). The system was sized to accommodate 3 bedrooms. The permit received final approval on December 22, 1994. An inspection was conducted on February 13, 2026. No clean out was observed between the residence and septic tank. The existing septic tank has 6-inch diameter risers that bring access to grade. Given the small diameter of the risers and depth of burial, it was difficult to gauge the exact distance to the top of the septic tank, but we estimate 6 to 7-feet. The water level appeared low, so we lowered a camera into the septic tank and captured video showing sludge build-up into the risers and on the sides of the septic tank, and liquid levels well below the outlet pipe, by several feet. No sanitary tees were present on either the inlet or outlet of the septic tank. We ran water from the residence, and it entered the septic tank normally. With these findings, we have determined the septic tank is leaking and must be replaced. The residence is served by a community water system. The existing STA will remain in use. We used Google Earth images and parcel mapping information from Garfield County GIS to create a site plan to the best of our ability to depict the approximate location of existing and proposed OWTS components. The site plan is not the result of a recent survey and locations are approximate. Page 2 View of approximate STA View of septic tank lids Looking into riser Liquid level appeared low Light and camera to video inside tank Page 3 DESIGN SPECIFICATIONS The existing septic tank will be abandoned by pumping the tank and removing it or filling the void with onsite materials. Design Calculations: 3 Bedrooms Minimum 1000-gallons The existing sewer lines may remain in use, and the elevation of these sewer lines must be verified at the time of excavation. Efforts will be made to relocate the new septic tank further southwest to achieve a shallower installation of the septic tank. The extent the septic tank can be relocated will depend on the existing location and elevation the sewer line that connects to the existing STA. Fall on sewer lines must be a minimum of 2% before the septic tank and 1% after the septic tank. Maximum burial depth of the septic tank should not exceed those listed by the tank manufacturer1. Typical maximum burial depth is 4-feet for most poly septic tanks. If backfill over the septic tank exceeds 4-feet, several measures may be considered to offset burial depth, including but not limited to the following: • Use BlueBoard insulation in place of soil directly over septic tank to offset the weight of the soil. • Create a retaining wall on the uphill side of the septic tank to minimize burial depth. • Utilize an H-20 rated lid on a concrete septic tank. This office must be present during excavation to verify sewer line elevation to determine if a shallower installation can be achieved, or if other measures are necessary. It was verified that the sewer line exits the residence approximately 8-feet below the finished floor elevation. Modification of the elevation of the sewer line exiting the house would be difficult (foundation wall, deck, etc.) The system installation must include a minimum 1000-gallon, two-compartment septic tank with an Orenco® Biotube Effluent Filter on the outlet tee. Any state-approved concrete or poly septic tank may be used. We have provided specifications for both a concrete and poly septic tank. Risers must bring the manhole lids to grade for access. An extension handle must be installed on the effluent filter. Effluent will gravity flow into the existing sewer line that that connects to the existing STA. A water test (run a garden hose for 10-15 minutes) must be run to assure the existing STA is accepting effluent. 1 Garfield County OWTS Regulation, 43.9 A.3 Page 4 COMPONENT SPECIFICATIONS The component manufacturers are typical of applications used by contractors and engineers in this area. CBO Inc. must approve alternative components prior to installation of the OWTS. Requests must be submitted, in writing, to our office for approval prior to installation. Component technical data sheets are available upon request. COMPONENT MANUFACTURER MODEL NO.

PERMIT APPLICATION INSTRUCTIONS An OWTS Permit Application (TANK ONLY) must be submitted to Garfield County Environmental Health Department. https://www.garfield-county.com/environmental-health/filesgcco/sites/16/OWTS-Application-Complete-Packet-Dec.-2019.pdf. If the OWTS Permit Application will be submitted with a Building Permit Application, it should be submitted directly to Garfield County Building Department. All questions regarding permit submission can be directed to Garfield County Environmental Health Department, 970-945-6614 x8150. INSTALLATION CONTRACTOR CBO Inc. expects that the installer be experienced and qualified to perform the scope of work outlined in this design. The installer must review this design thoroughly and coordinate with our office in advance of installation. Any additional conditions in this design or county permit must be completed and documented prior to final approval of the OWTS installation. Communication between the installer and this office is expected throughout the installation. INSTALLATION OBSERVATIONS CBO Inc. 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. CBO Inc. should be notified 48 hours in advance to observe the installation. In an effort to improve the accuracy of the record drawing, we request that the installer provide a sketch of the installation, including path of the sewer lines, water line installation (if applicable), septic tank location, STA location, and measurements from building corners or another fixed objects on the property. This sketch is most easily provided on Sheet W2.0 of the OWTS Design Page 5 Packet. Photographs of the installation and final cover are also requested to supplement our installation documentation. 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 irrigation 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 the backfilled STA. Machines with tracks (not wheels) should be used during construction of the STA for better weight distribution. Livestock should not graze on the STA. 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 STA. 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. ADDITIONAL CONSTRUCTION NOTES If design includes a pump, weep holes must be installed to allow pump lines to drain to minimize risk of 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 the 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. LIMITS: The design is based on information submitted. 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. Page 6 Please call with questions. Sincerely, CBO Inc.

Thompson Construction 720 East Cooper Avenue Glenwood Springs, Colorado 81601 Subject:Soils and Foundation Summary Report Lot 6 Westbank Mesa Development Garfield County, Colorado Job No. GS -1359 Gentlemen: This letter presents a brief summary of our foundation recommendations for the above referenced lot. This summary is provided for information and is not intended for foundation engineering purposes. Field and laboratory data and specific criteria developed for foundation recommendations are presented in our report dated September 19, 1994 The soils encountered in the test hole on this lot consisted of 0.5 feet of organic, sandy clays underlain by 7.5 feet of sandy clays underlain by 11 feet of clayey sands. No free groundwater was encountered. We recommend construction of the proposed residence on a spread footing foundation. Footings should be designed for a maximum allowable soil pressure of 3000 psf and be at least 16 inches in width. Isolated pads should be at least 24 inches square. Exterior footings should be protected from frost action with at least 3 feet of cover. The soils encountered exhibited low swell potential. Slab -on -grade construction involves a low risk of heave and cracking. We recommend the following precautions for slab -on -grade construction: 1.Slabs should be constructed directly on the soils. Provision of a sand or gravel layer increases the possibility of a single source of water wetting the entire area supporting the slab. 2.Slabs should be separated from exterior walls and interior bearing members with a joint which allows free vertical movement of the slab. 3.Slab- bearing partitions should be minimized. Where such partitions are required, a slip joint should be constructed to allow free vertical movement of the slab. 234 CENTER DRIVE • GLENWOOD SPRINGS, COLORADO 81601 • (303)945 -2809 4.Door jambs, sheet rock on partitions, and other construction details should be constructed to allow vertical movement of the slab - on - grade floor. 5.Eliminate underslab plumbing as much as possible. Where such plumbing is unavoidable, it should be pressure tested before the slab is constructed. 6.Plumbing and utilities should be constructed with a joint which allows the slab to move freely. 7.All connections between the furnaces and the duct work should be provided with a collapsible connection to allow free movement in the event of slab heave. The above precautions will not keep slabs -on -grade from movement, however, the risk of damage can be reduced if these precautions are followed. A subsurface drain is recommended for this residence. The drain should lead to a positive gravity outlet or to a sump where water can be removed with a pump. The ground surface around the residence should be sloped to provide a positive drainage away from the foundation. We recommend a slope of at least 12 inches in the first 10 feet surrounding the residence. We recommend no irrigation system sprinkler heads within 5 feet of the building and the head should direct water away from the residence. Irrigation should be hand watered within 5 feet of the residence. In our opinion landscaping with native vegetation is best. Roof downspouts should discharge beyond the limits of backfill. We recommend providing splash blocks and downspout extenders. Landscaping details should be carefully designed to avoid collecting surface water near foundations causing wetting of the supporting soils. We recommend against the use of plastic membranes below landscaped areas surrounding the foundation. Use of a non - woven, geotextile fabric will control weed growth, yet allow evaporation.

(100-mm) Biotube Effluent Filters, Biotube Jr., Biotube Insert Filters, and Biotube Base Inlet Filters are ideal for residential septic tanks and have a lifetime warranty. They prevent large solids from leaving the tank, dramatically improving wastewater quality and extending the life of residential drainfields. Standard Features & Benefits • Alarm available, to signal the need for cleaning • Flow modulating discharge orifices available to limit flow rate leaving tank, mitigat- ing surges and increasing retention time • Custom and commercial sizes available Effluent from the relatively clear zone of the septic tank, between the scum and sludge layers, horizontally enters the Biotube Effluent Filter. Effluent then enters the annular space between the housing and the Biotubes, utilizing the Biotubes’ entire surface for filtering. Particles larger than the Biotube’s mesh are prevented from leaving the tank. Optional Features & Benefits Biotube Filtering Process 8-in. (200-mm) Base Inlet Filter 4-in. (100-mm) Insert Filter 4-in. (100-mm) Biotube Jr. (4-in. Biotube cartridge avail- able separately as Insert Filter) Orenco’s superior effluent filters resist clogging better than all other brands.
