Changes must be approved by this Department and the engineer prior to construction. The existing tank will be removed and a new 3250 gallon FLXX 3-compartment tank and two Advantex AX-20 units (secondary treatment) will be installed. Effluent will be pumped to a central manhole, then entering the distribution pipes. Since the new field is proposed in the area of the existing field, the existing field must be removed. The new field will consist of distribution pipes set in 1 ft of /" washed rock over 6 ft of 1 Y" screened rock. The 6 ft of washed rock will be at different elevations due to the clay layer discovered in the southern portion of the drywell excavation. *In that half of the drywell, 4 ft of recompacted native soil will be installed to compensate for the "confining layer. Dimensions of each half of the drywell will be 20.5 ft x 51 ft. The inlet pipe will enter the manhole at the elevation specified on the engineer design. There will be a significant amount of backfill over the top of the field, with depths to vary depending on grading between the driveway contours. Calculation of the area was done using sidewall and bottom area (subtracting 66 sq ft for the large rock), as is typical to calculate area of a drywell. With the varying soil conditions, an "average" percolation rate of 110mpi was used, and calculating drywell capacity with percolation rates exceeding 60 mpi is not allowed per regulation. Using the deep gravel formula, the engineer has confirmed a length of 49 feet would be required. The system will have 51 ft of length, exceeding the minimum required capacity. This Permit must be kept on -site during installation. The engineer must do a final inspection of the installation and submit an "as -built" letter to this Department within 30 days of the final inspection, unless a longer period of time has been agreed upon, in writing. This Department must also be called for the final inspection with a minimum of 48 hours notice. Minimum horizontal distances between components of the system and physical features shall conform to the requirements of the Pilkin County OWTS Regulation. This Permit is conditioned upon the property owner(s) providing for regular inspection, cleaning, and maintenance of the system by qualified personnel, in accordance with the manufacturer's recommendations and the requirements of the Pilkin County OWTS Regulation. THIS PERMIT IS EXPRESSLY CONDITIONED UPON COMPLIANCE WITH ALL REQUIREMENTS OF THE PITKIN COUNTY OWTS REGULATION, INCLUDING BUT NOT LIMITED TO THOSE CONDITIONS SPECIFIED ABOVE.

RE: Terral OWTS — Parcel # 2735-033-00-024 Permit No. 08046A of 09/22/09 Dear Carla: With this letter we are also providing the plan as -built of the Terral OWTS. The swing -ties were provided by ICM Group. The system was observed during construction, and the design intent to deal with the slow percolation rates on the south-westerly side of the field was generally followed. The plan does not show any separation between the south-westerly side of the field and the north-easterly, because in fact there is none. The revised design for the two sides of the field is generally accurate, and can adequately serve as an as -built of the system. We observed the operation of the pumps and AdvanTex system, and all appeared to be operating satisfactorily. We are aware of no significant deviations from the design intent and the permitted plans (as revised). If this submittal meets with your approval, please copy me with the final permit by email. If you have any questions, please call me at (970) 948- 3149, or email me at tcpaae aPhotmail.com Sincerely, Gamba & Associates, Inc. T. Carter Page, P.E. Cc: Kurt Kelly, Michael J.

A reduction in absorption area may be made for gravel depth in excess of 6 inches below the bottom of the distribution pipe. The deep gravel reduction shall not be used if the absorption trench reduction is used. The reduction is calculated according to the following formula: (W+1+20) _ Where: L = Length required prior to adjustment. W = Width trench ebed, in feet _ d =Depth off gravel bellow distribution pipe, in feet. —� This formula returns a value that represents the revised length (call it "Lr") of the field, based on a thickness of gravel below the distribution pi e(s). —L In the case of the Terral Residence, with a fixed width 'W" of 41-feet, therequired length (prior to the deep gravel calculation) is the Minimum Re uired Area, divided b ty he avalilable width of 41-feet: L=A/W vVhere� L = Length required prior to adjustment. _ L = 2,158-sq.ft. / 4f-ft: W = Width of trench or bed, in feet. _ 61.5 feet Deep Gravel Formula: Lr=Lx(W+2)I(W+1+2d) - Vvhere:� Lr = Revised Length of field, in feet _ L =Length required prior to adjustment = 61.5 feet W = Width of trench or bed, in feet = 41 feet d =Depth of gravel, in feet = 6 feet Entering the known values into the formula, we get: _ Lr = 61.5' x (41' + 2)/(41 + 1 +2(6')) Lr = 61.5' x (43')/54') Lr=48.97' _ j Roundup to,49.-feet. _ Actual available length is 52, therefore the field is oversized somewhat (gravel is acutally deeper than required). I could have "backed into" the gravel depth, but instead made a quick on -site estimate (without the benefit of remembering the formulal), and arrived at a depth that I thought would be sufficient, without having an excessive mound over the field.

RE: Terral OWTS — Parcel # 2735-033-00-024 Dear Carla: Well, once again the Terral system has to undergo changes, this time precipitated by the conditions discovered at the bottom of the excavation for the drywell. What we found, in a nutshell, was as follows: 1. The southerly side of the field, closest to the house and garage, has significant areas of very clayey soils, some that formed near perfect "ropes" when rolled between the palms of one's hands. The clayey soils appear to be confined to the southerly side of the field, and do not extend into the sides, except at the extreme south corner, closest to the house. This side of the field was excavated deeper than we had anticipated, with the cut -slope approximately 18-feet deep. We had anticipated a maximum depth of approximately 16-feet. We are taking the approach that this side of the field has a bottom that is effectively a "confining layer". 2. The northerly side of the field, had some small areas of clayey soils, apparently isolated to the extreme north corner, otherwise, the bottom of the field percolated, though with highly variable rates (222-mpi to 5-mpi). 3. In addition, on the northerly side of the field, a very LARGE rock was encountered, which was too large to be removed with the equipment available. The decision was made to leave this rock in place, and adjust the area available on both the bottom of the field and on the sidewall of the field by the area "occluded" by the rock. Rough field measurements were made, and a conservative value was established for the bottom and side areas of the rock. decision was made in the field to deal with the confining layer on the ltherly half of the field by placing a minimum of 4-feet of native soils )m the segregated stockpile, choosing the topsoils and shallower soils) ich percolated at rates from 40-mpi to 12-mpi, based on our previous Is. This soil was kept separated from the gravel placed on the northerly Terral OWTS — Memo on Field Revisions ;day, July 15", 2010 1 of 3 half of the field by a separation fabric (either Mirafi 140-N, or 600X, per plans). The replaced native soils on the southerly side of the field serve to raise the gravel bed on that side above the confining layer by a minimum of 4-feet. In addition the native soil backfill places the gravel on that side on a level with the faster percolating soils previously discovered, so that the sidewalls will percolate at a reasonable rate. Above the native soil, the installed 1 1/2-inch minus screened rock has a surface area of 20.5-feet by 52- feet, and a depth of 6-feet (not including the 1-foot depth of washed rock at the top), giving a volume of 6,396-cubic feet. Within this rock volume, there is at least a 10% void space, or approximately 639-cubic feet of storage volume, equating to 4,784-gallons of liquid. On the northerly side of the field, there is approximately the some volume of rock, and correspondingly the same void space and storage volume, though the large rock will occupy perhaps as much as 450-cubic feet of space (a very conservative [i.e. large] volume estimate). The northerly and southerly halves of the field will be in contact and free to pass effluent between them from the bottom of the southerly field to the top of the northerly field, a height of approximately 2-feet. Disparities in the bottom and/or sidewall percolation rates between the two sides of the field will most likely allow more of the effluent to pass to the northerly side. The required minimum area of the absorption field, adjusted for the use of the AdvanTex advanced treatment system, and also adjusted for the use of a dosing pump in the third��ayl " compartment of the septic tank, is 2,518-square feet. The available area in the northerly field is as follows: X2�> Bottom Area: 20.5' x 52' = 1,066-sq.ft. Bottom Area occluded by rock: 57-sq.ft. (� k Available Bottom Area: 1,009-sq.ft. t L 1 Sidewall Area: (20.5' + 52' + 20.5') * 6' depth = y 558-sq.ft� 9Y Sidewall Area occluded b rock: 66-sa.ft. �'' �r, 3 Available Sidewall Area: 492-sq.ft. 51 ; y1' �3� TOTAL AVAILABLE AREA, NORTHERLY HALF: 1,501-sq.ft. l 1 0 31 On the southerly half of the field, the available areas are not compromised by the presence of a rock, and so are as follows: \` Bottom Area: 20.5' x 52' = 1,066-sq.ft. + Sidewall Area: (20.5' + 52' + 20.5') * 6' depth = 558-sg.ft. TOTAL AVAILABLE AREA, SOUTHERLY HALF: 1,624-sg.ft. COMBINED AREA AVAILABLE, BOTH HALVES OF FIELD: 3,125-sq.ft. qti' The available bottom and sidewall areas are approximately 1.24 times as large as the minimum area required (2,518-sq.ft.). New Terral OWTS — Memo on Field Revisions Thursday, July 151h, 2010 Page 2 of 3 The AdvanTex advanced treatment system will help minimize the formation of a bio-mat, and help keep the system from plugging. In addition, the fact that there are approximately 9,568-gallons of available storage in the void spaces of the gravel will help mitigate any areas of slower -percolating soils, by allowing a longer time for the effluent to drain.

Our site inspection of the proposed area for the absorption fields at this residence revealed an issue that needs further exploration to confirm our suspicions. In our inspection of the profile hole, we observed some evidence of water on the rocks and in the soil in one are of the hole. We believe that this mottling of the soils was due to the presence of an existing (and to be abandoned) absorption field for the original residence. This belief is based on the following information: 1. Original OWTS permit documents, showing an 18' by 51' gravel and pipe absorption field in the approximate area of the profile hole. 2. Review of the CTL/Thompson Soils and Foundation Investigation for the Terral Residence Additions of May 20, 2008, which includes the log of a bore hole drilled near the garage, showing that no water was found to a depth of 20-feet. A copy of that report is attached, refer please to Figures 1 and 2. 3. Review of the Soil Conservation Service soils maps and tables, showing that the two soils present in the area, "67" Jerry-Millerlake Loams, and "110" Uracca-Mergel Complex, do not have water at any depth up to 6-feet. In order to be sure that the absorption fields are not constructed in an area of high groundwater, we are proposing that the absorption field areas be excavated to the full depth as shown on the plans submitted with this letter, and that in each of the two fields, an additional 8-foot deep profile hole be excavated below the bottom of the field. The current plans show that the new profile holes would be excavated in the middle of the width of the fields, towards the southeast end of each field (the deepest end). If Pitkin OWTS — Submittal letter ay, August 11", 2008 1 of 3 County so desires, these profile holes could be pushed to the east side of each absorption field, and after excavation and inspection, a permanent observation pipe could be set in the excavation, and extended to the surface, for observation purposes throughout the year. In the unlikely event that groundwater is encountered in either of the excavations, we would revise the system drawings to provide for a minimum of 4-feet of separation between the top of the groundwater surface, or the top of the mottled soil layer, and the bottom of the absorption field(s). Because the three percolation tests made on this site were made at the standard depth of 3-feet below ground, and because the design of the proposed absorption fields extends to depths of approximately 10.85-feet below existing ground, we are proposing an additional series of percolation tests be performed at the actual proposed depth of the absorption fields. We are proposing that two additional tests be performed at the bottom of each of the excavations for the absorption fields, as shown on the design plans submitted with this letter. In the event that the percolation rate established by these supplemental tests is significantly higher than the design percolation rate of 40-minutes per inch used with these plans, we will revise the design drawings to accommodate the change. Our approach will be to use the "deep gravel" formula to accommodate the slower percolation rate. In the event that the percolation rate established by the supplemental tests is faster than the design percolation rate, we would propose no changes to the current design. It should be noted that the design percolation rate of 40-minutes per inch is the slowest of the three rates recorded in our testing on October 30, 2007. On the checklist for the OWTS plans package, an item to be explored is the location of any wetlands on the project site. While there has been no formal site inspection by the U.S. Army Corps of Engineers, nor by a qualified wetlands botanist/geologist, we feel confident, based on our site inspection, and review of the Soil Conservation Service maps and documentation, that the soils in the area are not at all conducive for the production of wetlands. Both the Jerry-Millerlake and Uracca-Mergel Complex soils present on the property are considered "Very Poor" or "Poor" soils for wetlands habitat, and do not have any wetlands species growing upon them. Our inspection of the profile hole showed a layer of topsoil, well vegetated, with roots, at varying depths of 6-inches to 1-foot. Below this was a tan Terral OWTS — Submittal letter Monday, August 1 Vh, 2008 Page 2 of 3 layer of soil and small rocks, about 1-foot deep, with fewer roots. Below this was a layer of sandy, rocky soil, with larger rock, to a depth of about 4- feet. The remainder of the profile hole was a darker brown soil with many rocks of all sizes from gravel to boulders, down to a depth of 8-feet. No free water was observed in the hole, and a perforated pipe was set in the hole for future observation. The site for the septic tank and the absorption fields have been staked in the field, no vehicular traffic or materials storage will be allowed over these areas.

RE: Terra[ OWTS — Parcel # 2735-033-00-024 Dear Carla: With regard to our communication of last week regarding the conditions encountered in the profile hole, I am sending with this letter, a series of photographs taken by our technician, Ted Kerns, at the time of the percolation testing, on October 30", 2007. In no particular order, the photos as hand -numbered show: #52: A view of the Profile Hole, looking toward the turn of the driveway, and the slope down into the hole. The mottling of the photo -left side (uphill side) of the hole, is visible at the arrow. #55: A close-up view of the left side of the Profile Hole, showing the mottling. The depth and location suggest that this is a result of the effects of the existing field, rather than groundwater. #57: Another view of the mottling on the left side of the Profile Hole. Mottling not present on the right side of the hole. #61: An overall view of the Profile Hole, this time looking from the curve of the driveway towards the deep end of the hole. Various layers of the soil profile are visible. #65: A view of the right-hand side (orientation left -right determined as in photo #52) showing the layers on the side of the hole, and the lack of mottling evident on this side. The approximate depths of the various soil layers visible in the photographs are as follows: • Topsoils with roots, from 0' to—0.75'; Dark brown to black, fewer rocks. • Sub -soil 2, fewer roots, from -0.75' to -2.5'; Tan with rocks, silty. • Sub -soil 3, very rocky, from -2.5' to -4'; Dark brown.

The applicant is proposing to add two new additions to the existing 5,097 square foot home, for a total of 8,000 square feet. DISCUSSION: The Pitkin County Environmental Health & Natural Resources Department has reviewed the details of the Terral Activity Envelope and Site Plan Review application under the authority of the Pitkin County Land Use Code and the Pitkin County Onsite Wastewater Treatment System (OWTS) Regulation, effective March 8, 2008, and has the following comments. On April 8, 2008, Carla Ostberg, Mike Kraemer, and Cari Ann Holcomb of the Pitkin County Community Development Department and Graeme Means, representative of the applicant, conducted a site visit to the property. Snow covered the site, which did not permit a good evaluation of the area of the existing septic system. The applicant did not indicate that an area for a new OWTS was being investigated. This alternative should be considered in the event that the existing system is not able to be used for purposes of establishing an Activity Envelope that could accommodate a new OWTS. --- WATER SUPPLY: This property is served by a private well. No well permit was provided in the application; however, in connection with any OWTS Construction Permit for the property, this Department will require a copy of the well permit issued by the Colorado Division of Water Resources, the well driller's report, and a recent pumping report. Under current guidelines, the well must be capable of producing 100 gallons/person/day (assuming 2 persons per bedroom in a dwelling). There must be storage or yield capable of a 24-hr supply. --- SEWAGE TREATMENT AND COLLECTION: The existing septic system on the property was originally permitted in 1977 and consisted of a 1250 gallon tank and 918 square feet of absorption area to accommodate four bedrooms. A drawing was provided to show approximate locations of the tank and absorption field. Pranted on Recycled Paper The owner's representative indicated that the new house would have five bedrooms. This existing system is not adequately sized to handle the addition of a potential bedroom. However, if the number of potential bedrooms in the home would not increase, it is possible that the existing system may be used, depending on its condition. There are two alternatives: 1. If the existing system is proposed to be used, it must be evaluated by a Registered Professional Engineer (RPE) and a report of the evaluation submitted to this Department for review. 2. If the existing system requires repair, or a new system is proposed, an OWTS Construction Permit issued by the Environmental Health & Natural Resources Department would be required, and must comply with the County's OWTS Regulation. The County cannot issue a Building Permit until an OWTS Construction Permit has been obtained, or the exiting system has been assessed as suitable to serve the proposed development. z panted on knyded raper Parcel Detail Page 1 of 3 Pitkin County Assessoir/T measurer Parcel Detail Information Assessor/Treasurer Property Search I Assessor Subset Query I Assessor Sales Search Clerk & Recorder Reception Search Basic Building Characteristics I Tax Information Parcel Detail I Value Detail I Sales Detail Residential/Commercial Improvement Detail Land Detail Photographs Tax Area Account Number Parcel Number I2007 Mill Levy 080 R003645 273503300024 41.458 Owner Name and Address TERRAL INVESTMENTS LTD LLC PO BOX 3595 ASPEN, CO 81612 Legal Description SUB:WEST BUTTERMILK LOT:4 DESC: A PARCEL IN N2SW4 SEC 3-10-85 DESC BY M/B BK 314 PG 126 Location Physical Address: I 178 ASPEN OAK DR ASPEN Subdivision: WEST BUTTERMILK Land Acres: 5.05 Land Sq Ft-j 0 2008 Property Tax Valuation Information Actual Value Assessed Value Land: 1,900,000 151,240 Improvements: 430,4001 34,260 Total: 2, 330,400 1 185,500 Sale Date: I 9/7/2007 Sale Price: 13,400,000 littp://www.pitkinassessor.org/assessor/parcel.asp?ParcelNumber=273503300024 7/7/2008 Parcel Detail Page 2 of 3 Basic Building Characteristics Number of Residential Buildings: 1 Number of Comm/Ind Buildings: 0 Residential Building Occurrence 1 Characteristics FIRST FLOOR: P50 GARAGE BUILT 1750 WOOD BALCONY: 632 UNFINISHED BSMT: 1,500 1/2 STORY: 560 Total Heated Area: 2,810 Property Class: SINGLE FAM RES-IMPROVEMEN Actual Year Built: I1978 Effective Year Built: 1982 Bedrooms: 3 Baths: 2.5 Quality of Construction: GOOD T 12 Exterior Wall: I WOOD SD GO Interior Wall: DRYWALL Floor: BASE Heat Type: HT WTR B/B Heating Fuel: GAS Roof Cover: METAL Roof Structure: GABLEMF Neighborhood: IBUTTERMILK AREAS Super Nbad: WEST ASPEN Tax Information Tax Year Transaction Type Amount 1997 Tax Amount $3,322.66 1997 Tax Payment: First Half 1997 Tax Payment: Second Half 1998 Tax Amount $2,006.86 1998 Tax Payment: First Half ($1,003.43) 1998 Tax Payment: Second Half 1999 Tax Amount $2,537.82 1999 Tax Payment: First Half 1999 Tax Payment: Second Half 2000 Tax Amount $2,918.52 2000 Tax Payment: First Half 2000 Tax Payment: Second Half http://www.pitkinassessor,org/assessor/parcel.asp?ParceiNumber=273503300024 7/7/2008 ADIINUNSTRATIVE DETERMINATION OF THE pMGN COUNTY, COLORADO, COMMUNITY 1 DEVELOPMENT DIRECTOR GRANTING APPROVAL FOR TIIE TERRAL ACTIVITY ENVELOPE AND SITE PLAN AND GMQS EXEMPTION FOR A TDR RECEIVER SITE Administrative Decision No. nA 2008 Tim Terra] (hereafter referred to as "ApplicanRECITALS t) has applied to the Community Development Director of Pitkin County, Colorado ("Director") for Activity Envelope and Site Plan Review for an addition to an existing legal single family residence. The Applicant is requesting use of one TDR for the addition. 1 The Applicant submitted an application after July 6, 2006, therefore, the application is being considered Pursuant to the 2006 Land Use Code, as amended. 2. The Lot is located at 178 Aspen Oak Drive and is within the Aspen Urban Growth Boundary (UGB), PID#: 2735-033400-024 (Legal Description, Attachment A). 3. The Lot is approximately 5 acres, is in the ARA 0 zone district, and is non -conforming in size. 4. The parcel is currently developed with a legal single family residence that received a Certificate of Occupancy in 1978. No other previous land use approvals apply. 5. The Applicant has indicated the intent to apply one TDR to this Lot for a maximum floor area of 81250 square fee Pursuant to Section 6-30-50(bxl) the Applicant is exempt from Special Review for a TDR because the Lot is located within the Aspen UGB, 6. The Lot is visible from Owl Creek Road. Staff has conducted a site visit and the proposed additions to the residence will not obstruct a ridgeline as viewed from this Road. The parcel is not mapped within any big game ranges. The Applicant has provided a wildfire report for the Lot which states it is encumbered by a high wildfire hazard- The Applicant has included slopes > 45% to the south and west of the proposed additions and along the driveway within the proposed envelope. The Applicant has argued that these slopes can be considered anomalies pursuant to Section 7-20-20(cx3). During Staffs site visit it was determined that these slopes are anomalies as they were created from the cut for construction of the existing residence and during driveway constnuction. However the area to the east of the residence contains slopes > 45% and is not an anomaly. 7. The Application was referred to the Aspen Fire Department, Buttermilk Metro District, Environmental Health and Natural Resources (EH/NR), and the CDOW. Comments were received from all and are outlined as conditions. 8. Public notice was published in the paper on March 30, 2008. No comments were received within 30 days. 9 The Director finds that the Lot is located within constrained areas however the constraints can be mitigated. APPROVED by the Director, subjec to the following coedit ons: 1. The Applicant shall adhere to all material representations made in the current or prior applications or in Public meetings or hearings and shall consider those representations to be conditions of approval, unless amended by other conditions.

The new Infiltrator Quick4 Trench system extends into a larger area, so additional percolation tests are proposed for the un-tested area of the field. 3) The design is based on a percolation rate of 40-minutes per inch. Subsequent testing in the area of the new abrorption trenches may reveal a different percolation rate. Revisions to the size of the absorption trenches may be required based on the results of the additional percolation tests. 4) The depth of the initial profile hole was approximately 8-feet below existing ground. A new profile hole will be excavated, and revisions to the design of the absorption trenches may be required, depending on the results of the examination of the profile Yole. 11a C nn Li I�I� 1: 1 1 • • - 1., • ..1: 1 � In `.iY • • - [NI FLXX 3 250—gal.

Upon examination of the information provided by Pitkin County for the existing Onsite Wastewater Treatment System, it appears that the mottling observed was created by the existing absorption field, and not the result of any groundwater. 6) Because of the extent of the proposed drwwell is beyond the area proposed in the original permit (#08046 of issued 03/09/08) an additional profile hole shall be required to confirm that there are no confining layers present. If, in the opinion of the engineer of record, the soil exposed at the bottom of the proposed drywell (1029.50±) is materially different in appearance or makeup than the soils in the original percolation test holes, an additional three percolation test holes will be prepared. After the three additional percolation tests are performed, the design depth of gravel for the drywell may have to be adjusted. Any confining layer (bedrock, water) found within the depth of the new profile hole will require an adjustment of the design to compensate. \ \ \ 31 LEGEND \ \ ___ - =_=_= �_-- i Approximate Existing Absorption Field** \ ® ® Existing Septic Tank \\ -ss-ss-ss Approximate Existing septic piping** - OWTS Profile Hole P472 OWTS Percolation Tests & Rates (#s 1 - 3) QEDProposed New Septic Tank Ax 20 Proposed New AdvanTex Treatment System 4" 4" 4" Proposed New Sanitary Sewer Pipe - 4-in 1.25"1.25"1.25"- Proposed New Effluent Discharge Pipe - 1.25-in.
