The 8.976 -acre property is located outside of Glenwood Springs, in an area where OWTSs are necessary. Legal Description: Section: 2 Township: 6 Range: 89 Subdivision: LUDINGTON MINOR Lot: 2 AS PER MINOR SUBDIVISION PLAT RECEPTION NUMBER 904764 8.976 ACRES Parcel ID: 2185-021-00-065 SITE CONDITIONS A 4 -bedroom, single-family residence presently exists on the property. The residence is served by existing OWTS. Garfield County Individual Sewage Disposal System Permit 3549 documents this system. The OWTS consists of 1250 -gallon, two-compartment concrete septic tank and 31 `Standard' Infiltrator® chambers in a trench configuration with 581.25 square feet of infiltrative area. The permit received final approval from Garfield County on November 15, 2001. A 1 -bedroom additional dwelling unit (ADU) is proposed above the garage. Plumbing exists in the proposed addition area and ties into the existing OWTS. The residence is served potable water from the community water system serving No Name. No water line will come within 25 -feet of any OWTS component. Prior to beginning work, the existing water line must be located. An addition to the existing soil treatment area (STA) is proposed. SUBSURFACE The subsurface was investigated by Kumar and Associates and results are outlined in a report dated July 18, 2018, Project Number 17-7-100.01. The subsurface was explored by digging two profile pits and running three percolation tests. Percolation tests were 10 minutes per inch (MPI), 10 MPI, and 20 MPI. A gradation was performed from a sample from Test Pit #2 approximately 5 to 6 -feet below grade. Results were 8% gravel, 37% sand, 35% silt, and 20% clay. Tests are consistent with a soil classification of Sandy Loam, Soil Type 2. A long term acceptance rate (LTAR) of 0.6 gallons per square foot will be used to design the OWTS. Page 2 DESIGN SPECIFICATIONS A new tank will be installed to accommodate the additional capacity necessary to accommodate the 1 - bedroom ADU and square footage will be added to the existing STA. Design Calculations: 4 -bedroom Main House Design Flow = 525 GPD 1 -bedroom ADU Design Flow = 150 GPD Total design flow = 675 GPD LTAR = 0.6 GPD/SF 675 GPD / 0.6 GPD/SF x 1.0 (gravity trenches) x 0.7 (chambers) = 787.5 SF For the purposes of this OWTS design, Benchmark Elevation at the garage slab has been established as 100' (sewer line as it enters existing septic tank). ALL SERVICE septic, LLC should be notified of any discrepancies or problems with grade elevations of proposed components during installation of the OWTS. OWTS Component_ Minimum Elevation Primary Tank Inlet Invert Min. 100' Distribution Box Min. 99' Upper Trench Min. 98.5' The existing 1250 -gallon septic tank must be abandoned by pumping and crushing the top, bottom, and sides and filling the void with onsite material. A new, 1500 -gallon, two-compartment Infiltrator@ septic tank with an effluent filter must be installed. If more than one riser is added to the septic tank, an extension handle must be installed on the effluent filter. The existing sewer line must be re-routed to enter and exit the new septic tank. We have located the existing distribution box and have placed a pink flag in that location. The existing distribution box is 4' 4" below grade. A new distribution box must be installed. The existing sewer lines must be re-routed into and out of the new distribution box. The new distribution box must be installed at a higher elevation than the existing distribution box, while accommodating existing elevation of the sewer lines entering and existing the septic tank. The new distribution box must be accessible from grade. Flow Equalizers, or similar product, must be installed on each outlet pipe. Effluent gravity flows to the existing STA, which consists of 31 `Standard' Infiltrator@ chambers and a total of 581.25 square feet of infiltrative area. An additional 206 square feet of infiltrative area must be added to the existing STA. Two rows of 9 `Quick 4' Infiltrator® chambers must be installed to the north of the existing STA. Trenches must be separated by at least 4 -feet of undisturbed soil. Inspection ports must be installed at the beginning and end of each trench. 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. Page 3 INSTALLATION CONTRACTOR ALL SERVICE septic, LLC 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 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. 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 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 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 STAs. 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. Page 4 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 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. 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. Sincerely, ALL SERVICE septic, LLC Carla Ostberg, MPH, REHS Reviewed By: T ' Richard H.

We understand our findings will be used by others in the design of the on-site wastewater treatment system (OWTS). This report summarizes our findings and general design recommendations based on the subsoil conditions encountered. The services are supplemental to our professional services agreement with Red House Architecture dated December 16, 2016. Background Information: We previously performed a geologic hazards review for the proposed ADU development and submitted our findings in a report dated February 22, 2018, Project No. 17-7-100.01. The subsoils at the site consist of Loam and Gravelly rocky Sandy Loam (per the USDA soil classification system) with varying amounts of gravel and cobbles and no groundwater to the maximum depth explored of 8 feet. Proposed Construction and Field Exploration: The proposed soil treatment area (STA) location with respect to the proposed ADU is shown on Figure 1. Two profile pits (Profile Pits 1 and 2) were excavated and three percolation tests were performed at the proposed STA at the locations shown on Figure 1. The soil profiles are shown on Figure 2. The soils encountered at the profile pits consisted of about 1 to 2 feet of organic topsoil overlying nil to 6 feet of Loam underlain by rocky Sandy Loam with gravel, cobbles and small boulders. No free water or indications of seasonally shallow groundwater were observed in the pits. Gradation (minus 3 -inch fraction) and hydrometer (minus No. 10 size sieve) analyses were performed on a disturbed bulk sample of the soils from Profile Pit 2 with the results provided on Figure 3. The tested sample classifies as Loam per the USDA system. Based on the subsurface conditions and laboratory testing, we have classified the design soil Loam as Soil Type 2A per County and State regulations. Red House Architecture July 18, 2018 Page 2 Percolation testing was conducted on July 13, 2018 in hand dug holes in the bottoms of backhoe pits in the STA with a mean percolation test result of about 20 minutes per inch (mpi). The percolation tests were not performed in accordance with State Regulation #43 specifications but to provide a general comparison with the profile pit evaluations. Discussion: The profile pit evaluations at the STA indicate a long-term acceptance rate (LTAR) of 0.50 be used at this site for Treatment Level 1 (TL -1) for a system based in the Loam or Gravelly Sandy Loam soils. Limitations: This study has been conducted in accordance with generally accepted geotechnical engineering principles and practices in this area at this time. We make no warranty either express or implied. The conclusions submitted in this report are based upon the data obtained from the exploratory pits excavated at the locations indicated on Figure 1 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 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. If you have any questions or need further assistance, please call our office. Sincerely, H-PKUMAR Steven L.

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 WARRANTY AND REMEDIES IN SUBPARAGRAPH (a) ARE EXCLUSIVE. THERE ARE NO OTHER WARRANTIES WITH RESPECT TO THE UNITS, INCLUDING NO IMPLIED WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE (c) This Limited Warranty shall be void if any part of the chamber system is manufactured by anyone other than Infiltrator. The Limited Warranty does not extend to incidental, consequential, special 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. For this Limited Warranty to apply, the Units must be installed in accordance with all site conditions required by state and local codes; all other applicable laws; and Infiltrator's installation instructions. (d) No representative of Infiltrator has the authority to change or extend this Limited Warranty. No warranty applies to any party other than the original Holder.
