P.O. Box 535 Eagle, CO 81631 Re: Septic System Inspection 2291 Brush Creek Rd. Eagle, Colorado Project No. 92685E Dear Mrs. Pearch: At the request of Ted Reynolds, I visited the site at 2291 Brush Creek Road, Town of Eagle, Colorado for an inspection of the. septic disposal system being installed. The system had been installed in general compliance with the Revised Septic Recommendations provided by this office, dated December 1992, under Project No. 92685E. A few minor details varied from the recommendations given but should not effect the performance of the system. Mr. Reynolds has proposed to.cover the system for the winter with imported fill material rather than topsoil as was recommended. This is acceptable providing that in the spring, this fill material is removed and topsoil is put in its place. Fertile topsoil is very important to the performance of the system and must be placed as soon as it has thawed and is workable. The Meyers S54-11 Effluent Pump that was recommended in the design was replaced by an equivalent pump, the Hydromatic OSP33 Submersible Sump/Effluent Pump. The pumps were switched to make ordering and receiving the pump easier for Mr. Reynolds and the performance of the system should not be effected by the switch. If you have any questions, please do not hesitate to call.

BITE INVE'B IOATION An investigation of the site was done on October 12, 1992 to determine the subsurface and groundwater conditions for the proposed residence.. At the time of that investigation, groundwater was found at 3 feet in the test pit. (refer to soil and Foundation Investigation, Project No. 92650G, dated October 1992). The soil profile consisted of 3 feet of TOPSOIL, underlain by 3 feet of clean sandy GRAVEL with cobbles. On November 16, 1992, an investigation was done on the soil in the area of the proposed septic system. Groundwater was found in the pit at 3.5 feet of depth. The soil profile consisted of 1 foot of TOPSOIL, underlain by 0.5 feet of reddish brown SILT with some roots, underlain by 2 feet of moist Silty SAND. BITE LOCATION AND DMfiCtsYlo►T10N The site is a 2.5 acre lot located in the NE 114 of Section 9 T. 5 S., R. 84 W., between the west side of Brush Creek Road and the east side of Brush Creek, Eagle County, Colorado. The topography of the lot is relatively flat. ---- ----_ . -.1 yes Y'04 DEC 10 ' 92 12: 14 2 ZRAC ELATION TBST RESULTS No percolation tests were performed due to the high groundwater stable. A mound system with a pump was considered due to the elevations and high groundwater table. The natural. soil texture was classified as sand/sandy loam. According to Table 7-10 from the EPA manual, a percolation rate of 0-30 min/in is assigned for this soil, with an Infiltration Rate of 1.2 gpd/ft. DESIGN CRITERIA A single family residence is planned for this site. The residence will be a two bedroom modular house with one bathroom, a clothes washer and a garbage disposal. The system was herein designed in accordance with the procedures outlined in the EPA design manual and the Eagle County Regulations for Individual subsurface Sewage System. The following criteria will be used. Gcoupancy = 2 persons per bedroom Average Flow = 75 gallons per person per day Peak Flow = 150% of average flow Groundwater located at 3.5 ft. depth DEGION CALCUL_AmToNs For reference to lettered dimensions in the calculations, refer to appendix one.

SEPTIC RECOMMENDATIONS Recommended is a minimum 750 gallon, 2 compartment septic tank followed by i1 pump tank containing a Myers S54-11 Effluent Pump. This will be followed by a mound type septic disposal system. This system will have a minimum 375 square foot absorption bed surrounded by a minimum so foot X 39 foot basal area as ,shown on the plans. The system boundaries must be at least to feet inside all property lines. A swale should be formed at the boundary of the mound system in order to route surface water away from the mound. Topsoil Containing vegetation should be removed within the boundaries of the mound system prior to beginning construction. An inspection of the system should be made by a representative of Inter --Mountain Engineering, Ltd., prior to backfilling.

All topsoil with vegetation must be stripped from the mound area prior to construction. 2. A minimum 750 gallon, 2 compartment septic tank is required. 3. The elevation of the building sewer invert has been assumed to be 100.34 based on the elevation of the SE property corner of the adjoining southern lot being 100.00. All other elevations are based on that assumptions. If the actual elevations of the building sewer invert varies from the assumed elevation, contact Inter -Mountain Engineering for adjustment of all other elevations. 4. The surface of the bed is not suitable for active sports or flagstone patio. 5. Breathers, as detailed, should be placed at all four (4) corners of interconnected distribution pipes to aerate the disposal field. 6. Distribution lines and manifold should be laid level. J 7. This system should meet all applicable Eagle County Health Department rules and regulations as set forth in the Individual Sewage Disposal System Regulations of that department. 8. A representative of Inter -Mountain Engineering, Ltd., should be contacted for inspection prior to placement of backfill.
