We understand that the design of the individual sewage disposal system will be designed for an 1805 sf three-bedroom home. H-P Geotech has conducted preliminary soils investigations. Pertinent sections of reports transmitted to SGM are attached. Under my supervision and in accordance with Colorado "Guidelines on Individual Sewage Disposal Systems", Revised 2000, Section VII, you conducted the required percolation tests on August 28, 2001. (The holes were actually pre-soaked each of the previous three nights; the first two in anticipation of pare tests by the county.) My mid-test site visit revealed a fairly homogenous and dry, eight-foot deep soil profile excavation without bedrock and three percolation holes in conformance with the state guidelines. The profile and pare holes were located north of the house. You reported the slowest percolation rates in each of the three pare holes as: Hole #1 = 19.8 mpi, Hole #2 = 18. 7 mpi, and Hole #3 = 15.4 mpi. The initial H-P Geotech report identified significantly slower percolation rates for Ukele Acres, ranging from 80 to 160 minutes per inch. I believe this was the result of saturated, groundwater conditions resulting from flood irrigation. It my understanding that flood irrigation will not be used In this area in the future. Given that groundwater was not encountered in your soil profile excavation or the 11 /20/00 H-P Geotech investigation, I believe that future percolation rates should correspond to your site specific test results rather than the initial H-P figures. I would recommend using a design percolation rate of 30 mpi. Noting that H-P Geotech was performing simultaneous pare test on five other Ukele Acres lots on 8/28/01, you should find out the results when they become available. I should be notified if tests on adjacents lots differ significantly from your figures. Based upon the percolation test results and the soil observations, it appears that a standard 6 SCHMUESER I GORDON MEYER ENGINEERS ~ SURVEYORS August29,2001 Kim Mechling Page2 GLENWOOD SPRINOS I 18 W.

CO 8 I 224 070-340-!53!5!5 F'l(; 070-340-5358 leach field system can be installed on this site. This, of course, assumes that setback requirements can be met in accordance to Colorado State Health Department regulations. Accordingly, we have attached a table from the Colorado Department of Public Health & Environment ISDS regulations, which identify the required setbacks for each component of the septic system installed. The proposal for this site as far as method of disposal considers the use of a standard "Infiltrator" system. This system, as proposed, will be installed in a trench-type fashion. Accordingly, we have attached manufacturer's product information regarding the Infiltrator and the Infiltrator system installation. To briefly describe the septic system as a whole, it is proposed to collect the effluent from the main waste line from the house to a 1 ODO-gallon (min.) septic tank. You have indicated that a concrete tank will be installed so I will forego a discussion of anchoring fiberglass tanks in case of unexpected groundwater. Please note that the septic tank must be located at least five feet away from the residence. In addition, the effluent line leaving the house and going to the septic tank must be straight in alignment and straight in grade. If it is deemed necessary that a change in alignment and/or grade in this main line from the house to the septic tank is required, a cleanout will be necessary to accompany the installation. This main line coming from the house to the septic tank must be a minimum 4" diameter. The grade of the pipe must be a minimum of Y." per foot. If it becomes necessary that a main line must cross a traveled area (i.e., vehicular access), we would then recommend that the pipe specifications be increased in strength, use Schedule 40 PVC in place of the ASTM 3034 designation. To compensate for differential settling between the septic tank and the incoming and outgoing piping, we would recommend that, through the zone of backfill for the tank, the piping coming into and leaving the septic tank be sleeved in a 6" diameter cast iron or Schedule 40 PVC. Once the effluent line leaves the septic tank, it will need to proceed towards the infiltrator trench system at a W' per foot grade. Again, the minimum diameter of this pipe would need to be 4". We would recommend that, from this point to the infiltrator system, location of the infiltrator system and piping be situated such that no vehicular access is allowed over the piping or the infiltrator system. Additionally, with this recommendation, we would then maintain that the ASTM 3034 PVC piping be utilized. For the disposal system itself, we would recommend installation of a minimum of three standard infiltrator trenches comprised of 14 units each. We have attached our calculations, which define the length of infiltrator trench necessary, as well as the number of infiltrator units necessary per trench. The closest spacing that the infiltrator units can be installed is 1 O feet on center. It is imperative for the proper function of the system that, the infiltrator units be placed in a flat, level trench. We have attached a sketch, which identifies the typical piping requirements to equally distribute flow to each of the infiltrator trenches. As previously discussed, we have attached the manufacturer's literature regarding the infiltrator system. With the manufacturer's literature, is a detailed list of instructions regarding installation of the septic system. You will note that the backfill required over an infiltrator trench is native backfill. This native backfill is acceptable for fill over the trenches as long as 6" and larger rock is not allowed in the backfill. The minimum requirement of 12" of cover 6 SCHMUESEi.R GORDON MEYER ENGINEERS & SURVEYORS GLENWOOD SPRINOS I I 8 W. 6TH, SUITE 200 GLENWOOD SPRINGS, CO 81 60 I 070-045-I 004 ASPEN CAESTEO BUTT!: P.O.

All materials, installation practices and setback requirements shall comply with Garfield County Individual Sewage System Regulations. The infiltrator trench shall be constructed so that the bottom of the trench is level ± 0.1 foot. Place trench in natural ground, no portion of the trench shall be placed in fill. Once backfilled, provide positive drainage way from the trenches. The area, disturbed by construction, shall be reseeded by native grasses to prevent erosion. Use risers as needed to bring septic tank access hatches within 6" of finish grade. Locate septic tank such that the access to the tanks can be accommodated for future pumping. The Contractor and Owner shall take whatever measures are necessary to assure that (a) the septic tank and sewerlines are completely watertight to prevent infiltration of groundwater in the system, and (b) the system is installed to prevent freezing of the gravity sewerlines. No irrigation to be allowed over trenches.

It is the Contractor's responsibility to verify all locations of utilities and setbacks that may be affected by the installation of the septic system. Verification of all utility locations shall be made with the appropriate utility company. 9. Substitution of materials (i.e., pipe, tanks, etc.) is acceptable, provided verification and acceptance by the Engineer and the Garfield County Sanitation Department is made. As you can gather from reading this report, we are leaving the specifics (i.e., exact location, grades and elevations) of the installation of the system to the Contractor andfor yourself. It is important to note, however, that the location of the septic system must be provided in the same general location of the percolation test holes. In essence, if the septic system is located on a site different than where the percolation test was taken, verification of the percolation rates must be made by SGM prior to final installation of the leach field. If it is determined that the information as provided is not of sufficient detail for your Contractor andfor yourself to construct the system, please notify us immediately and we can provide a detailed construction plan for the system. To accommodate such a detailed construction plan, SGM would have to coordinate with you, to collect detailed topography in the area of the proposed septic system. Aside from the comments just made, I hope this information is of sufficient detail to accommodate your needs in installing this septic system. If you have any questions or comments, please call.

Water should not be allowed to pond which could impact foundations or roads. To limit infiltration into the bearing soils next to buildings, exterior backfill should be well compacted and have a positive slope away from the building for a distance of 10 feet. Roof downspouts and drains should discharge well beyond the limits of all backfill and landscape irrigation should be restricted. SEPTIC DISPOSAL SYSTEMS Percolation tests were conducted to evaluate the feasibility of infiltration septic disposal systems at the site. Percolation test borings were drilled near Borings 2 through 6. The test borings were soaked with water one day prior to testing. The percolation test results are presented in Table II. The results ranged from 80 to 160 minutes per inch and averaged 120 minutes per inch. Based on the typical silty and sandy subsurface conditions encountered, we expect infiltration septic disposal systems should be feasible. The auger holes may have been somewhat sealed by the clayey soils. Additional tests in hand dug holes should be performed for design of the individual septic systems. LIMITATIONS This study has been conducted according to 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 obtained from the field reconnaissance, the exploratory borings located as shown 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 borings 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 so that re-evaluation of the recommendations may be made.

Dear Mr. and Mrs. Smith: As requested, Hepworth-Pawlak Geotechnical, Inc. performed additional exploration along the proposed access road into the subdivision. Hepworth-Pawlak Geocechnical, Inc. previous conducted a geologic hazards assessment and I>reliminary geotecbnical study for the proposed development and presented our findings in repons dated October 2S and November 11, 1999, Job No. 199 751. In the preliminary study, six borings were drilled in the proposed development area. The subsoils encountered in th,e exploratory borings generally consist of about ~ foot of topsoil overlying relatively loose to niedi.um dense, statified sand, silt and clay. Groundwater was encountered in the borings at depths of S to 11 ~ below the ground surface. The overlying soils were slightly moist to very moist. We understand that the pavement design, provided by Schmueser Gordon Meyer, consists of a ~-inch chip and seal overlying 12 inches of Class 6 road base. Scarification and compaction of 12 inches of the subgrade is planned prior to placement of the roadway section. We understand that a1 the time of our field work in September 1999, the property was belni flood irrigated which may have attributed to the shallow groundwater and very moist upper soils. The additional subsoil study consisted of observing 4 exploratory pits excavated along the proposed access road into the property. The subsoils encountered consist of medium dense, statified sand, silt and clay. No free water was observed in the pits to the depths. excavated of 6 to 7 feet and the upper soils were slightly moist to moist. We expect that the groundwater level fluctuates with field irrigation in the area. Based on our experience with similar soils for a residential cul-de-sac, 12 inches of road base appears appropriate. Asphalt pavement or subbase beneath the Class 6 road base, H33!03~ d-H . . .. .. Rop & Jean Smith November 20, 2000 Page2 could be used with a thinner road base section. We can assist Schmueser Gordon Meyer with design parameters for the other options. Other recommendations presented in our previous report which are applicable should also be observed. If there are any questions or if we may be of further assistance, please let us know. Sincerely, HEPWORTH -PAWLAK GEOTECHNICAL, INC. Jordy Z. Adamson, Jr., P.E. Rev. by: SLP JZA/ksw cc: John L.
