Pitkin County, Colorado Job No. 10946 Ms. Greenwood, As requested, we observed the installation of the onsite wastewater system (OWS) for the subject site on March 16, 2000. The system was designed under our Job No. 10946, dated June 21, 1999 and revised December 6, 1999. The system includes the installation of a 2000 -gallon, single -compartment, precast concrete septic tank followed by a 1000 -gallon two-compartment precast concrete septic tank with a pump in a Biotube vault. Two mounded chamber -beds were installed with 4.5 feet of imported sand filter material, as indicated on Figure 1, each bed having 4 rows of 11 chambers. The drain field is 110+ feet from all bodies of water and 160+ feet from the well. The pump, alarm, and Biotube vault were in place and wired at the time of our visit. Troy Buster, with Aspen Earth Moving, may activate the pumping system at his discretion. The components of the OWS were installed in conformance with our plans and specifications.

ENGINEERS & GEOLOGISTS December 6, 1999 Gretchen Greenwood 520 Walnut Street Aspen, Colorado 81611 Subject: Revised OWS Design, Proposed Lederer Residence Section 4, T9S, R66W, e P.M. Pitkin County, Colorado Job No. 10946 Dear Ms. Greenwood, As requested, we are providing this revised OWS design for the subject site. The revision is based on a change in the site plan, and the measured depth to water, from our June 21, 1999 design letter. The revisions include reorientation of the mounded field and clarification of the depth of sand filter material in the mound. This letter should be used in conjunction with our original design. This letter includes two revised figures, Figures 2 and 3. The original Figures 2 and 3 should be removed to avoid confusion. RECOMMENDATIONS - The OWS proposed includes: two septic tanks with a pump in a Biotube vault and two mounded pressure distributed chamber -bed drain fields with imported sand filter material at the locations presented on Revised Figure 2. The OWS design is based on an average sewage load of 1750 GPD and a percolation rate of 21 MPI. We recommend installation of one 2000 -gallon single -compartment precast concrete septic tank to be followed by a 1000 -gallon, single -compartment, pre -cast concrete septic tank with a biotube-vault pump. We recommend the installation of two chamber -beds, each with 4 rows of 11 chambers, with 4.5 feet of imported sand filter material. Six inches of topsoil should be removed under the proposed fields and replaced on top of the mounded drain fields to promote growth after installation,. A pump is required for pressure distribution and to distribute the effluent through the field to increase the efficiency of the field. We recommend a total flow rate of 40.7 Gallons Per Minute (GPM) and a Total Dynamic Head of 29.8 feet. The proposed OWS is not oversized for section rotation and rotation should not be done. The surface of the drain fields should be seeded. We recommend using a native seed mix. 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. No landscaping or plastic can be installed over the fields, which will reduce performance of the fields. LIMITATIONS - An OWS design requires installation by a contractor who is experienced in its installa- tion. 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. If the health department makes modifications to this design, we should be contacted to evaluate the impact on the performance of the OWS.

The 100 year floodplain was determined through a HEC II analysis conducted by Schmueser Gordon and Meyer, Inc.. The building envelope is more readily understood by examining the 1041 Site Plan in Attachment 1. 'the site will be accessed via a level driveway from Capital Creek Road an depicted by Attachment 1.

Seel Attachment 3 to this application for the letter summarizing the findings of the floodplain study. As the FEMA maps were not specific in the subject's immediate neighborhood, the study located the exact location of the 100 year floodplain on the property. Based upon the information derived from the study, the floodplain impacts, as shown in Attachment 3, are minor. In the worse case, minor encroachments of the floodplain onto the property occur in a very small area near the northern boundary. The building envelope has been adjusted to be entirely outside of the 100 year floodplain. Therefore the floodplain hazard area is not within the proposed building envQlope. wildlife 3asards A deer migratory corridor crosses the eastern side of the subject property. we have discussed the situation with Randy Cote of the Colorado nivision of wildlife. Randy indicated that the building envelope should be placed on the west side of the property away from the migratory route. Therefore, as shown on tho 1041 situ plan, the building envelope is on the western side of the site and avoids the wildlife hazard. Although essentially flat, the property gently slopes downhill to the eastern side of the property where the deer will retain an uninterrupted migration corridor. 1 �gG/p8?1998 1— 06 8157448aA3 Ellen sassano November 11, 1992 page 5 SCHELLING DEV P';at 07 Bootions 5-103 G 2-12 Compatibility with Historic and Archaeologioal Itenourcosn sr� There are no known historic and archaeological resources affected by the proposed development.

Thera is the possibility that a shallow well could be completed in the shallow alluvial materials which occur at the site, but it is more likely that the domestic water source will be from a deeper well completed in underlying bedrock formations. The latter is typical of the majority of the wells in this area. Dean Gordon anticipates that well yields will be in the range of 5 GPM to 15 GPM.

Lederer Residence, Snowmass, Colorado, was successfully drilled under attached well permit no. Nlli-37254 to a depth of 41 feet. Static water level in this alluvial well was measured at 15 feet and a two hour pump test was completed indicating the well is capable of yielding more than 15 gallons per minute. This pumping rate is more than adequate to meet the needs of the proposed Lederer Residence. The well has been specifically sited within the building envelope to meet all required setback requirements. An exempt well permit is now being processed by the District Engineer's Office for Water Division 5 (see attached) and this property qualifies for the issuance of an exempt permit. The well permit will be i„ued for 15 gpm with a right to fully supply the Ledcrcr residence including the irrigation of up to one acre of lawn and gardens and the watering of domestic stock- In addition to this permit, irrigation of the remaining land upon the property will continue under the historic, decreed surface water irrigation rights in the 13oram & White Ditch and the Little Elk Creek Ditch. Upon receipt of the permit we will install the appropriate pump and water will be available for use during construction. Finally, there is every indication this well will provide a reliable source of potable water for the Lederer property. The lire storage tank bids have been roccivcd and fie storage requirements will be met by the installation of a single tank sized to meet all fire flow requirements, Potable water storage will be required to provide a supply capable of meeting instantaneous demands.

ENGINEERS & GEOLOGISTS June 21, 1999 Gretchen Greenwood 520 Walnut Street Aspen, Colorado 81611 Subject: OWS Design, Proposed Lederer Residence Section 4, T9S, R66W, 6t' P.M. Pitkin County, Colorado Job No. 10949 Dear Ms. Greenwood, As requested, we have evaluated subsurface conditions and designed an onsite wastewater system (OWS) for the proposed residence at the lot. Our firm conducted percolation tests on May 21, 1999. SITE CONDITIONS - The site is located in a rural area of Pitkin County, Colorado. There is a slight southerly slope at the proposed field. There is a good cover of native grasses in the proposed field area. PROPOSED CONSTRUCTION - A five -bedroom residence between with 2000 and 6000 square feet (SF) is proposed as presented on Figure 1. The OWS design was based on 5 bedrooms and a 1000 gallons per day (GPD) loading using Aspen/Pitkin Environmental Health Department (APEHD) loading of 100 gallons per day per person. The loading with a peaking factor of 1.75 is 1750 GPD. This loading includes a dishwasher, garbage grinder, and washing machine. The residence will be served by public water. SUBSURFACE CONDITIONS — Six percolation tests were performed in holes 27 to 44 inches deep and a test pits was excavated at the locations indicated on Figure 1. Subsurface conditions consisted of 1.0 foot of topsoil, underlain to the maximum depth explored of 8 feet by very sandy clay with gravel and scattered boulders. Ground water stabilized at a depth of 5 feet on May 26, 1999. Percolation tests indicate percolation rates of I 1 to 30 minutes per inch (MPI). The average percolation rate is 21 MPI. RECOMMENDATIONS - The OWS proposed includes: two septic tanks with a pump in a Biotube vault and two mounded pressure distributed chamber -bed drain fields with imported sand filter material at the locations presented on Figure 1. The OWS design is based on an average sewage load of 1750 GPD and a percolation rate of 21 MPI. We recommend installation of one 2000 -gallon single -compartment precast concrete septic tank to be followed by a 1000 gallon single -compartment pre -cast concrete septic tank with a biotube-vault pump in the second compartment. We recommend the installation of two chamber -beds, each with 4 rows of 11 chambers, with 2.5 feet of imported sand filter material. Six inches of topsoil should be removed under the proposed fields and replaced on top of the mounded drain fields to promote growth after installation. A pump is required for pressure distribution and to distribute the effluent through the field to increase the efficiency of the field. We recommend a total flow rate of 40.7 Gallons Per Minute (GPM) and a Total Dynamic Head of 29.8 feet. The proposed OWS is not oversized for section rotation and rotation should not be done. DENVER 4501 Wadsworth Boulevard Wheat Ridge, CO 80033 CASTLE ROCK 303.660.4358 303.463.9317 Fax: 303.463.9321 EVERGREEN 303.816.1455 w OWS Design Job No. 10946 Page 2 If additional bedrooms in unfinished areas are possible, we recommend the OWS be constructed to serve the additional loading. This OWS design will serve a five -bedroom residence. For greater than five -bed- rooms, the septic tank must be upsized 438 gallons for each additional bedroom. Each additional bedroom would require an additional 258 SF of field, which is equivalent to 17 gravelless chambers. A new permit is required by APEHD if the OWS is to be upgraded. The surface of the drain fields should be re-established to approximate the natural slope and then be reseeded. We recommend using a native seed mix. 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. No land- scaping or plastic can be installed over the fields, which will reduce performance of the fields. OPERATION AND MAINTENANCE - The owner must realize an OWS is different from public sewer service, and must assume the responsibility for maintenance of the OWS. The system is relatively mainte- nance free, but the owner must have the septic tanks pumped. We recommend the septic tank be pumped and the biotube vault be cleaned every two years. There are daily considerations, such as not putting plastic or other nonbiodegradable material into the OWS. Water use must be monitored so toilets are not allowed to run when seals malfunction. To illustrate the point, a running toilet can consume in excess of 1000 GPD. A loading of 1000 GPD could flood and irreparably harm the OWS. The loading from the backwash of a water softener may be harmful to the OWS. A separate drywell should be constructed for the backwash waste, if a softener is installed. Chemically treated water from pools or spas should not be introduced to the OWS. LIMITATIONS - An OWS design requires installation by a contractor who is experienced in its installa- tion. 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. If the health department makes modifications to this design, we should be contacted to evaluate the impact on the performance of the OWS. All construction is to be in accordance with the ISDS regulations. Pipe type and size, burial requirements, septic tank construction, 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 APEHD ISDS regulations and requirements. If there are any questions or if we can be of further service, please call.
