The system was designed under our Job No. 13498W, dated April 20, 2001 and revised May 6, 2002. The system includes a 2000-gallon, two -compartment, precast concrete septic tank with an effluent filter on the outlet, and five chamber -trenches with a concrete distribution box and serial overflow distribution. Three trenches had 1 row of sixteen chambers each, one trench had 1 row of 15 chambers, and one trench had 1 row of 10 chambers for a total of 73 chambers and of 1131.5 square feet of infiltrative area. An as - built drawing is included as Figure 1. The components of the OWS were installed in conformance with our plans and specifications. Sincerely, CHURCH & Associates, Inc. Timothy R.

We have prepared a revised onsite wastewater system (OWS) for the proposed residence. The revision is based on a change in the drain fend configuration frorn our original design, dated April 20, 2001. The percolation test was performed on April 16, 2001. Our original design should be. discarded to avoid confusion. Sff E CONDMONS The lot is located in a residential area in the subdivision of Cordillera, in Eagle County, Colorado. The proposed dmLn fold area has a -moderate- to steep slope to the north. 'i hm are scattered aspen and evergreen trees in the proposed field area. r—ROPOSED COINST"RUCTION A six-hedroom_ residence is proposed at the location presented on Figure 1.

If additional bedrooms are anticipated, we recommend the OWS be sized for the jai build- out number of bedrooms- Trenches should be installed no deeper than 4 feet. u witty discharge cannot be achieved our office should be contacted for details regarding pump specifications. M^-: nt aver the dr�i!! figlrl trench hnttnm dt ri!ig c�snsti��ction should be kept at a minimum to prevent compaction of the receiving soils. We recommend the bottom of each trench be scarified with a pick, shovel, or packhoe bucket teeth prior to the addition of dispersal gr .dell. OPERATION AND ALUV MANCE The distribution device (Flow Splitter Basin or distribution box) must be observed at end of one year to confzrr_n or assure even disthbution. The owner must realize an OWS is different ?torn public sewer service, and must assume the responsibility for maintenance of the OWS. The system is relatively maintenance free, but the over trust have the septic tams pumped. In the absence of a monitoring program, we rfonimend ;.optic tank be pumped and the effluent filter cleaned every two years. There are daily considerations, such as not putting plastic or other nonbiodegradabie material into the OWS. rater use must be monitored so toilets are not allowed to nut when seals malfunc-tiori. To illustrate the point;. a running toilet can consume in excess of 1000 GPD. A loading of 1000 GILD could flood and irreparably harm the OWS. The, lnaamling fr�,n, tlZe hackwaGh of a water softener may be hart�nfiil tq the OWS. A s parate drywell should be constricted for the backwash waste, if a softener is installed: Chemically treated water from a swimming poor or spas should not be introduced to the O "J. An OWS design requires installation'by a contractor who is experienced in its installation. Our imr-estig-atimn, layout, design and reeomtuendations are based on data submitted. If subsurface conditions considerably different from those described m tills report are encountered; we should be notified to evaluate the effect on the proposed OWS: Vthe health department makes modifications to this desiQ,xi, we should be contacted to evaluate the impact on the perffinTtarice of"the OWS. All construction is to be in accordance with the ISDS regulations. Pipe type and size, burial requirements, septic tank constniction, and 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 ISDS regulations and requirements. If there are questions or f We fiu'ther service, please call.

Director Dear Tim: I spoke with Ed Church about this OWS design a few weeks ago on the phone. I gave him the following design concerns at that time: The system design from Church & Associates is based upon 900 gpd which is the maximum loading rate for a 4-bedroom house. The maximum daily loading rate for a six -bedroom house according to Eagle County ISDS regulations and State of Colorado guidelines is 1350 gpd. Assuming the HP average perc rate of 28 min/inch is accurate, the LTAR is 0.6 gal/sq.ft/day. Therefore, 1350/0.6 = 2250 sq. ft. 2250sq/ft/31 = 73 infiltrator chambers. The Church design specifies 48 chambers for a trench configuration. 2. Split flow devices and/or distribution boxes are not recommended by Eagle County ISDS Regulations. However, they may be acceptable to resolve a site specific condition; i.e., isolation distances, grade elevations, soil types, etc. The Hlavacek property does not appear to have site conditions that require the use of a split flow device. Upon further review I also have concern with the profile hole and perc tests performed by HP GeoTech in 1998. Eagle County prefers to observe a profile hole and recommends that Church & Associates perform a perc test in accordance with procedures outlined in a 2001 letter to HP GeoTech which is enclosed for your reference or by using another professionally recognized methodology. The percolation test can be conducted by Eagle County EH for conventional systems after adequate site preparation. Please call and schedule an appointment at least 48 hours in advance. Do not hesitate to call me at 970-328-8758 or my cell (970-471-4743) if you have any questions or further input. el Community Development Department (970) 328-8730 FAX (970) 328-7185 TDD (970) 328-8797 Email: eccmdeva@vail.net http: //www.eagle-county.com June 12, 2001 EAGLE COUNTY; COLORADO Jordy Adamson, P.E. Hepworth-Pawlak Geotechnical, Inc. 5020 County Road 154 Glenwood Springs, Colorado 81601 Re: Specifications for Percolation & SoiI Profile Test Holes Dear Mr. Adamson: Eagle County Building P.O. Box 179 500 Broadway Eagle, Colorado 81631-0179 Per your request this letter shall serve to clarify Eagle County's instructions to engineers performing percolation and soil profile test holes on properties intending to design individual sewage disposal systems. The following specifications are located in the Eagle County How To Obtain an Individual Sewage Disposal Permit (ISDS) handout included with each application form: • Soil Profile Hole: The 8 feet soil profile examination should be located in an area directly. adjacent to the proposed absorption area. Soil profiles within a proposed absorption field are discouraged due to changes in soil texture. If your absorption area is located on a slope, dig your soil profile hole down slope of the proposed area. • Pere test holes: Backhoe cuts impact the upper natural soil strata leaving depressions within the absorption field area. The percolation test holes should be dug with a post hole digger or spade. The dimensions of the holes should be approximately six (6) inches in diameter and three (3) feet deep. The holes cannot be more than twelve (12) inches in diameter. Accepted percolation test methodologies can be found in many technical publications, including the EPA design manual. This office would be happy to provide this information, if necessary. This department would actually prefer engineering firms replace the traditional percolation tests results with a soil profile hole report that includes a long term soil acceptance rate (LTAR) recommendation. A representative from this department will observe the soil profile hole during the required site evaluation of the property.

Hiiffittan, As requested by the Eagle i,ou* Healtil Dep linent, we have revisal onsitc - to —ater system (OWS) for the proposed residence. The revision is based on a change in the design criteria from our revised design, dated. April 4, 2002. This letter and attached figares should be used in conjunction with our revised OWS desigm Sr FEE k.iJN —0l l P71"1S The lot is located in a residential area in the subdivision of Cordillera, in Eagle County, Colorado. The proposed drain field area has a moderate to steep slope to the north. There are scattered aspen and ever- green trees in the proposed firefd area. SUBSURFACE CONDMONS Hp C7eotech perfolTnef'r a subsul-face investigation by d.,ggmg o»e profile pit, at the location indicated ou Figure 1. Subsurface materials reported consisted of 2.5 feet of topsoil, underlain by sand and rock frag- ments. to the maxiinum depth explored of 9 feet. No ground water or bedrock was encountered_ Pet lat on test results indicate percolation rates of 16 to 40 minutes per inch (MPI). The average percolation rate is 28 Mpl. used on county requirements, we sizing 'the drain field based on the published LTAR table. The soil encountered is a sand and gravel, -which,, according to Eag_lc County yields an LTAR of 0.6 gal/SF/day. P_v,c0 WND- A. -:10N_ S The OUTS sl*uld include installation of one 2000-gallon, two-com;�artment septic tank with an effluent filter on the outlet and five chamber trenches with a distribution device and overflow fines as presented on Figure 1. A Flow Sputter Base or distribution box may be used acid should be placed on gravel pa,' to ensure even distribution. Five trenches are required; four must have one row of 15 chambers, and one must have one row of 13 chambers, for a total of 73 ch.,ainbers. The ONNS design is based on an average sewage load of goo rp ) and an I TAR of 0.6 galSVSF/day. If additional bedrooms are anticipated, we recommend the oWS be sized for the final build-oJ number of bedrooms.
