ENGINEERS & GEOLOGISTS June 14, 2004 Bill Poss & Associates Attn: Norman Tai 605 East Main Street Aspen, Colorado 81611 Subject: Revised OWS Design, Proposed Henry Cottage Rick Henry Parcel, Perry Christensen Subdivision Pitkin County, Colorado Job No. 16109W Mr. Tai, As requested, we have prepared a revised onsite wastewater system (OWS) for the proposed cottage. The revisions are based a change in living area to the cottage and more accurate placement of the percolation testing area on the site plan from our original design, dated November 14, 2003, under Job No. 16109W. All previous designs should be discarded to avoid confusion. The subsurface investigation was performed November 5, 2003. SITE CONDITIONS The property is in a rural residential area in Pitkin County, where OWS are required. The proposed drain field area has an approximate 4% slope to the northwest and a moderate cover of native grasses. The residence will be served by an onsite well located 132+ feet west of the proposed drain field. PROPOSED CONSTRUCTION A four-bedroom residence with a living area of 5500 square feet (ft) is proposed at the location pre- sented on Figures 1 and 2. The OWS was sized based on 4 bedrooms and 800 gallons per day (GPD) using Pitkin County Environmental Health Department (PCEHD) loading of 100 gallons per day per person. The loading with a peaking factor of 1.75 is 1400 GPD. This loading includes washing machines and garbage grinders. If additional bedrooms in unfinished areas are possible, it is suggested that the OWS be constructed to handle the additional loading. The installation of a properly engineered OWS to serve future build -out can be cost effective. SUBSURFACE CONDITIONS A subsurface investigation was performed by digging three percolation holes, 36 to 38 inches deep and one profile pit at the locations indicated on Figure 2. Subsurface materials in the profile pit consisted of DENVER 4501 Wadsworth Boulevard Wheat Ridge, CO 80033 www.geo-church.com 303.463.9317 Fax: 303.463.9321 Toll Free -1.877.248.3123 Revised OWS Design Job No. 16109W, 6/14/04 Page 2 organic, clayey sand to the maximum depth explored of 8 feet. Ground water was not encountered. Percolation tests indicate percolation rates of 15 to 20 minutes per inch (MPI). The average percolation rate is 17 MPI. Percolation data is included as Table 1. RECOMMENDATIONS The installation must include a septic tank with an effluent filter and a gravelless chamber -trench drain field installed at the locations presented on Figure 2. The OWS design is based on an average sewage load of 800 GPD and a percolation rate of 17 MPI. The installation includes one 2000 -gallon, two- compartment, precast concrete septic tank with an effluent filter on the outlet and three chamber - trenches, each with one row of 13 chambers for a total of 39 chambers and 604.5 ft2 of infiltrative area. A flow splitter basin, or equivalent, is required to distribute effluent to the fields. Vehicle movement over the trench area during construction should be kept at a minimum to reduce compaction of the receiving soils. The bottom of the bed should be scarified with a pick, shovel, or backhoe bucket teeth prior to the addition of 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. 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 OWS. In the absence of a monitoring program, the septic tank should be pumped every two years or more frequently, if needed. The effluent filter is to be cleaned during pumping or as needed. There are daily considerations such as not putting plastic or other non -biodegradable materials into the septic system. Garbage disposal use should be minimized to reduce the frequency of pumping of the tank. Water use must be monitored so toilets are not allowed to run when seals malfunction. To illustrate the point, a running toilet can use in excess of 1000 GPD. An additional 1000 GPD loading may flood and irreparably harm the system. We caution against the installation of a water softener. The hydraulic loading from the backwash of a water softener is detrimental to an OWS and a separate drywell should be constructed for the backwash waste, if a softener is installed. No landscaping or plastic can be used over the field, which will reduce performance of the field. Chemically treated water from a swimming pool or spas should not be introduced to the OWS. The design of the OWS is based on the treatment of domestic sewage only. No industrial or hazardous wastes should be introduced into the OWS. LIMITATIONS Our investigation, layout, design and recommendations are based on data submitted. If subsurface conditions considerably different from those described in this report are encountered, we should be notified to evaluate the effect on the proposed OWS.

Patrick Henry Jr. and Mildred M. Bollen Family Trust ("Applicant") have applied to the Pitkin County Community Development Director (`Director") to amend the previously approved 1041 Hazard Review to relocate the access to the approved building envelope. The new access will cross Hunter Creek; the Applicant proposes to culvert the creek in this location. 2. The parcel is located on the east side of Snowmass Creek Road, beyond Shield O Mesa and Terrace, and is described as the "Rick Henry Parcel," according to the Third Plat Amendment to the Perry Christensen Subdivision and the Mosbacher Lot Line Adjustment Plat, recorded February 1. 1994 in Plat Book 33 at Page 79. 3. The property is zoned RS-30/PUD and contains approximately 40.3 acres. 4. The parcel was legally created and configured prior to May 8, 1972 and has not merged with adjacent properties; therefore, it is exempt from growth management for up to 5,750 square feet of floor area. 5. The Hearing Officer granted 1041 Hazard Review, Conceptual Submission, Special Review, GMQS Exemption and Caretaker Dwelling Unit approval on June 18, 2002, pursuant to Determination No. 18- 2002. 6. The Director finds that the proposed amendments do not create any additional impacts on 1041 areas, will not change the use of the proposed development or the basic character of the land, are consistent with action taken during the original review, do not increase off-site impacts, and will not endanger the public health, safety or welfare. 7. The Director further finds that Hunter Creek has an intermittent Flow and the installation of a culvert will have limited impact that can be mitigated; therefore, it is unnecessary to bridge the creek. THE DIRECTOR DOES HEREBY APPROVE the Henry 1041 Hazard Review Amendment, subject to the following conditions, which shall run with the land and be binding on all successors in interest. I ) The conditions of Hearing Officer Determination 18-2002 shall remain in ful I force and effect, except as amended herein. 2) Prior to submission of any earthmoving, access or building permit applications, the Applicant shall submit an amended 1041 Hazard Review Site Plan to the Community Development Department for approval and recordation. The mylar copy of the site plan must be signed by the owner prior to submittal for recording.

The plan shall specify the mitigation site and methods (including transplanting of existing materials), and erosion control measures. The plan shall be submitted with the access/driveway permit. Financial security in the amount of s 1,000 shall be required to ensure the survival of the vegetation. 4) The Applicant shall adhere to all material representations made in the application.
