West Bank Mesa Development. Garfield Countv Dear Randy: Per your request, SGM has evaluated the design of the proposed septic system to service the residential flows from Lot 9 of West Bank Mesa Development. This work follows previous foundation work performed by SGM (Job #94090B). With that previous structural /foundation work, it has been determined that the house is a 4- bedroom residence. In addition, we are in receipt of a report prepared by CTL/Thompson identifying the percolation rate for Lot 9, West Bank Mesa. In CTL/Thompson's test results, we have identified the average percolation rate for this lot to be 20 mpi. We have attached a copy of the percolation test results as part of this report. With percolation test results, we have also attached a copy of boring logs prepared by CTL/Thompson. A summary of the boring logs identified that the septic system (or leach field system) will be installed in clayey, sandy, stiff to very stiff, slightly moist to moist and brown soil. Based upon the percolation test results and the soil borings, it appears that a standard 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 Health 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 1250 gallon septic tank. Please note that this 1250 gallon concrete septic tank does have alternative installations available. These alternative installations can be considered, considering the fact that no evidence of high groundwater is present. The alternative installations that can be considered with this type of septic tank is that of a fiberglass septic tank also equal to 1250 gallons. We have not provided information as to a specified manufacturer or product line for fiberglass septic tank. 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 July 7, 1995 in alignment and straight in grade. If it is deemed necessary that any 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 at a minimum ASTM 2729 PVC pipe of minimum 4" diameter. The grade of the pipe must be at a minimum of '/." per foot. If it becomes necessary that the main line must cross a traveled area (i.e., vehicular access), we would then recommend that the pipe specifications increase in strength to no longer utilize an ASTM 2729 designation but rather use a Schedule 40 PVC. To compensate for differential settling between the septic tank and the incoming and outgoing piping, we would recommend that the piping coming into and leaving the septic tank be sleeved in a 6" diameter cast iron pipe or Schedule 40 PVC. Once the effluent line leaves the septic tank, it will need to proceed towards the infiltrator trench system at a '/." per foot grade. Again, the minimum diameter of this pipe would need to be that of 4 ". We would recommend that, from this point to the infiltrator system, location of the infiltrator system and piping be coordinated 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 2729 PVC piping be utilized. For the disposal system itself, we would recommend that three infiltrator trenches be installed. 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 10 feet on center. The infiltrator units must be placed in a flat 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 that manufacturer's literature is a detailed list of instructions regarding the septic system installation. You will note that the backfill required over an infiltrator trench is that of 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 over the infiltrator system is also identified. Please note that the infiltrator must be installed in an excavated trench and not in fill. As mentioned throughout this report, a number of attachments are included with this report. Please find the following list which identifies specifically the attachments in order: 1. Calculation of leach field and septic system sizing. 2. Table of minimum horizontal setbacks. 3. Soils profile logs. 4. Percolation test results. 5. Schematic plan view of septic system installation. 6. Sketch of the standard infiltrator chamber. SCHMUESER GORDON MEYER, INC. July 7, 1995 7. Infiltrator manufacturer's literature. 8. Septic system installation instructions (from Infiltrator manufacturer literature. Some general notes that must be mentioned regarding any septic system installation are as follows: 1. All materials, installation practices and setback requirements shall comply with Garfield County Individual Sewage Disposal System Regulations. 2. The infiltrator trench shall be constructed so that the bottom level of the trench is t 0.1 inches. Place trench in natural ground, no portion of the trench shall be placed in fill. Once backfilled, provide positive drainage way from the trenches. 3. The area disturbed by construction shall be reseeded by native grasses to prevent erosion. 4. Use risers as needed to bring septic tank access hatches within 6" of finish grade. 5. Locate septic tank such that the access to the tanks can be accommodated for future pumping. 6. The contractor and owner shall take whatever measures are necessary to assure that (a) the septic tank and sewerlines are completely water -tight to prevent infiltration of groundwater into the system, and (b) the system is installed to prevent freezing of the gravity sewerlines. 7. The engineer and Garfield County Department shall be notified when construction commences and kept abreast of the construction progress so that sufficient inspections can be performed to assure conformance with this report. 8. 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 Building Department is made. As you can gather from reading this report, we are leaving the specifics, (i.e., exact location, grades and elevation) of the installation of the system to the contractor and /or yourself. It is important to note, however, that the location of the septic system must be provided in the same general location of that identified with the boring logs of CTLIThompson. In essence, if the septic system is located on a site different than where the percolation test was taken, SCHMUESER GORDON MEYER, INC. July 7, 1995 verification of the perc rates must be made by either CTUThompson or 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 and /or 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 yourself collection of 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 don't hesitate to call. Sincerely, SCH ESER O DON MEYER, INC. fil 1 I Jef : : • imonson, P.E. JSS. • 1 .41 =0.1 Encl. ure SCHMUESER GORDON MEYER, INC.

SCOPE This report presents the results of our soils and foundation investigation for thirteen (13) residential Tots at the Westbank Mesa Development in Garfield County, Colorado. We explored the subsurface conditions at the lots to provide foundation recommendations for single family buildings. This report includes a description of the subsurface conditions found in our test holes, recommended foundation systems and geotechnical and construction criteria for details influenced by the subsoils. Our report was prepared from data developed during our field exploration, laboratory testing, engineering analysis and our experience with similar conditions. A summary of our conclusions Is presented below. SUMMARY OF CONCLUSIONS 1. We found approximately 6 inches of organic, sandy clays on lots 1, 3, 19, 23, 24, 36, 40 and 46. Below organic soils we founded stiff to very stiff, slightly moist, sandy clays to depths of 15 to 20 feet in borings drilled on lots 3, 9, 19, 45 and 46. The clays were underlain by medium dense to very dense, slightly moist to moist, silty to clayey sands to as deep as 25 feet on lots 1, 8, 23, 26, 36, 40 and 44. On lot 24 we found 12 feet of silty to clayey sands underlain by sandy clays. No free groundwater was found in our test holes the day of drilling. 2. We recommend founding the buildings with footings bearing on the native clays and sands. A maximum soil bearing pressure is presented in the 'Foundations' section. 3. Slabs -on -grade floor subgrade will be the native, undisturbed sands and clays. The native soils are appropriate for slabs -on -grade if significant moisture increase in bearing soils does not occur. 4. A ground surface slope away from the buildings should be maintained at all times to reduce the risk of wetting soils below foundations. Native vegetation is recommend near the buildings. we investigated are below. Lot 1 Lot 1 is adjacent to and west of Delores Circle. Ground surface slopes were measured and visually estimated at 10 to 30 percent from the northeast down to the southwest. Vegetation is native grasses and sage. Lot 3 The lot is adjacent to and north of Delores Circle. Ground surface slopes were measured and visually estimated at 5 to 15 percent from the southeast down to the northwest. Vegetation is native grasses and sage. Lots 8 and 9 Lots 8 and 9 are adjacent to and east of Delores Circle. The west two- thirds of the lots ground surface slopes are at grades measured and visually estimated at 10 percent from east to west. The west one -third of the lots ground surface slopes are at grades as steep as 50 percent from the west down to the east. Vegetation is native grasses and sage. Lot 19 This lot is adjacent and south of Huebinger Drive. The ground surface slopes at an average of about 22 percent from the south down to the north. Vegetation Is native grasses and sage with several oak and pine trees on steeper areas. Lots 23 and 24 These lots are adjacent and west of Native Lane. Ground surface slopes were estimated at 5 to 15 percent from the north down to the south. Vegetation is native grasses and sage on the Tots and scrub oak and pine trees on the slopes at the ravine to the west. 3 SATURATION AND PREPARATION "? 4 +t ' I�' 7� � '+ 3'( A la i� r DATE: 6/02/94 4 " . . i) \i4n I.)i 1\ ty 1 M✓ TIME AT START OF SATURATION: 9sOOAM �%' A,. /r`,�a 1 thi $ Y;1artri l , .V .l d. -t;1 J>_1 ,jots, i PERCOLATION TEST RESO 'TS JOB NO.

Roof downspouts and drains should discharge well beyond the limits of all backfill. Splash blocks or downspout extensions should be provided at all discharge locations. PERCOLATION TESTS We performed percolation tests on each of the subject lots. Based on our test results standard percolation fields are appropriate on the subject lots. The table below list the lot and recommend design percolation rate. Appendix A presents data obtained during the tests. 1.
