Box 11362 Aspen, Colorado 81611 Subject: Subsurface Investigation and OWS Design, Proposed Residence Lot 21, Filing 3, Aspen Mountain View, Missouri Heights Eagle County, Colorado Job No. 14618W Mr. Walker, �? -7�'�� As requested, we have designed an onsite wastewater system (OWS) for the proposed residence. The subsurface investigation was performed by Hepworth-Pawlak Geotechnical, Inc. on September 28, 2001. SITE CONDITIONS The property is in a rural area in Eagle County, where OWS are required. The proposed drain field area has a 10% slope to the south-southeast and a dense cover of native grasses and sagebrush. The residence will be served by the local water district. PROPOSED CONSTRUCTION A four -bedroom residence with a living area of 3000 square feet (SF) is proposed as presented on Figure 1. The OWS was sized based on 4 bedrooms and 600 Gallons Per Day (GPD) using Eagle County Environ- mental Health Department loading of 75 gallons per day per person. The sewage loading with a peaking factor of 1.5 is 900 GPD. This loading includes washing machines and garbage grinders. SUBSURFACE CONDITIONS H.P. Geotech performed a subsurface investigation by digging one profile pit and three percolation holes, at the locations indicated on Figure 1. Subsurface materials consisted of 6 inches of topsoil, underlain by sandy clay to 4 feet, underlain by sandy silt with basalt fragments and boulders to the maximum depth explored of 8 feet. No ground water was encountered. Percolation tests indicate percolation rates of 20 to 60 minutes per inch (MPI). The average percolation rate is 42 MPI. Percolation data is presented as Appendix A. RECOAUdENDATIONS The installation must include a septic tank and a mounded chamber -type drain field installed at the locations presented on Figure 1. The mounding is based on Eagle County wanting 4-feet to the basalt boulders. We C 0-6 would prefer a 2-foot depth of installation of the chambers, which would not require mounding, beO will V have to be authorized by Eagle County. The OWS design is based on an average sewage load f 6 and a percolation rate of 42 MPI. The installation must include one 1500-gallon, two-compartm , ecast concrete septic tank with a pump in a Biotub-im vault, and four mounded chamber wrenches, each with 1 row of 10 chambers. Six inches of topsoil must be removed beneath trench area and replaced with six inches of imported sand filter material. The topsoil should be stockpiled and replaced on top of mound to promote DENVER 4501 Wads t h Boule and 303.463.9317 e; CO 80033 303.463.9321 CASTLE ROCK 303.660.4358 EVERGREEN 303.816.1455 LOVELAND 970.663.2124 WESTERN SLOPE 970.948.5603 o Subsurface Investigation and OWS Design Job No. 14618W Page 2 re -vegetation. A 1.25-inch PVC line must be suspended- within chambers with 1/8-inch holes drilled on three-foot centers, with holes upward and every fifth hole facing downward. A pump with a total flow rate of 36.6 gallons per minute and total dynamic head of 20.2 feet is required to pressurize the drain field. Pump specifications are included as Figure 4. p r, Vehicle movement over the field area during construction should be kept at a minimum to reduce compaction of the soils. The trench area should be scarified prior to installation of sand and chambers. The surface of the field should be seeded after installation of the trenches. A native seed mix should be sown at the trench area to revegetate the surface. These mixes do not require irrigation and develop a growth 10 to 15 inches high. No automatic sprinkler system should be installed over the fields. OPERATION AND MAINTENANCE The owner must realize an OWS is different from public sewer service. The owner must be aware of and assume responsibility for maintenance of the system. In the absence of a monitoring program, the septic tank should be pumped every two years. Effluent filter and screened vaults, as applicable, .are to be cleaned during pumping. There are daily considerations such as not putting plastic or other nonbio- degradable materials into the septic system. Garbage disposal use should be minimized. The backwash of a water softener may be harmful to the OWS. A separate drywell should be constructed for the backwash waste, if a softener is installed. Chemically treated water from a swimming pool or spas should not be introduced to the OWS. LIMITATIONS Our investigation, layout, design and recommendations are based on data submitted. If subsurface condi- tions considerably different from those described in this report are encountered, we should be notified to evaluate the effect on the proposed OWS. If the health department makes modifications to this design, we should be contacted to evaluate the impact on the performance of the OWS. The county and our firm must be contacted upon completion of the OWS --- -�o All construction is to be in accordance with the ISDS regulations. Pipe type and size, burial requirements, septic tank construction, a -Lid other specifications, which are not depicted in our report, are to conform to the requirements of the ISDS regulations. The installer of the system is to have demonstrated knowledge of the Eagle County Environmental Health Department ISDS regulations and requirements.

S) Landscaping which requires regular heavy. irrigation should be located at least 5 feet from the building. Consideration should be given to the use of xeriscape to limit potential wetting due to irrigation-. Percolation Testing.-.- Percolation. tests were. conducted_ on -September 21,.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- holes are- similar to- those exposed- irk Pit 2 excavated near the septic disposal area and shown on Fig. 2 and consist of 1/2 foot of topsoil and 31h feet of stiff to very stiff sandy clay overlying relatively dense basalt fragments up to boulder size in a calcareous sandy gilt matrix to the pit depth of S feet. The percolation test results are presented in Table H. The percolation test results indicate an infiltration rate between 20 and 60 minutes per inch with an average of 42 minutes per inch.

Walker, Per discussion with Laura Fawcett, we are providing the attached addendum of our December 11, 2001 OWS Design. Eagle County has requested the OWS be sized on long term acceptance rates (LTAR) per the EPA Design Manual. Based on the EPA Design Manual the LTAR for a 42 MPI percolation rate is 0.6 gallons per square foot per day. Using the LTAR, a minirrlum of 48 chambers is requirzd. Instead of four trenches with 10 chambers, the installation will require four trenches, each with 12 chambers, as presented in Revised Figures 1 and 2_ The trenches must be mounded, pressure distributed, and have 6 inches of imported sand filter material Alt other recommendations in our report dated November 11, 2001 must be followed..

We recommend a minimum slope of 12 inches- in -the first 10 feet in unpaged, areas and a minimum slope of 3 inches in the first 10 feet in pavement and walkway areas. A swale may be needed 'uphill to direct surface runoff around the residence.. 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. Consideration should be given to the use of xeriscape to limit potential wetting due to irrigation: Percolation Testing-.- Percolation -tests were. conducted- on_September.. 21,.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 holes are- similar to- those exposed- in- Pit 2 excavated near the septic disposal area and shown on Fig. 2 and consist of 1/2 foot of topsoil and 314 feet of stiff to very stiff sandy clay overlying relatively dense basalt fragments up to boulder size in a calcareous sand} silt matrix to the pit depth of g feet. The percolation test results are presented in Table II. The percolation test results indicate an infiltration rate between 20 and 60 minutes per inch with an average of 42 minutes per inch. 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 expressed or implied. The conclusions and recommendations submitted in this report are based upon the -data- obtainedfrom the, exploratory pits excavated at the locations indicated on Fig. 1, the proposed type of construction 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. This report has been- prepared for the- enlusi-ve 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 H-P- GEGrECK 415 Laura Fawcett From: Eric Burns [eburns@geo-church.com] Sent: Friday, May 21, 2004 9:35 AM To: Laura Fawcett Subject: Walker Residence cleanout pics a a a walker house 5 18 walker house 5 18 walker house 5 18 00002.JPG (6... 00003.JPG (6... 00004.JPG (5...

He said that there is a cleanout installed, it's under the deck, and that he is going to cut an access port in the deck. He said he will send me pics when it's complete and I'll send you a new letter and drawing when he does. Thanks. -----Original Message ----- From: Laura Fawcett[m ai Ito: Laura.
