BOX 179 EAGLE, COLORADO 81631 FAX: (303) 328-7185 The Environmental Health Division would like to notify you to make a formal request to extend your Individual Sewage Disposal System(ISDS) Permit #1410-94 into the 1995 construction year. The Environmental Health Division discontinued percolation tests on November 15, 1994 and final inspections on December 2, 1994 due to climatic conditions. ISDS permits are active for 120 days after the date of issue if no Building Permit has been issued for the same property. If a Building Permit has been issued for the same property the ISDS will expire at the same time as the building permit. If you still plan to apply for a Building Permit this year or in the early months of 1995 you will need to have a percolation test conducted before your Building Permit will be released. You will have to contact a Registered Professional Engineering(RPE) firm to conduct your percolation test. If you have had your permit issued and have not had your final inspection completed, but plan on constructing the system in the next few weeks, please give our office a call and we will evaluate your permit on a case by case situation.

O. Box 10255 Aspen, CO 81612 Subject: Soils Evaluation and Percolation Test for Individual Sewage System Design for a 3.6 acre lot, A parcel of Land in Tract 61, Section 12, T8S, R87W of the 6th P.M., numbered as 22501 Old State Highway 82 Dear John, As requested, Nelson Environmental and Wastewater Solutions, Ltd., performed another soils study and percolation test on the subject property to design a septic system for the residence under construction. We conducted this study according to Section 4.05 of Chapter IV of the Eagle County Code - Individual 19AM Diauosal Systems on Friday, August 26, 1994. We have based our recommendations on the subsurface conditions encountered. We will furnish this letter to the Eagle Environmental Health Department at our earliest opportunity so that they may complete the permit to construct this sewage system. Proposed Construction: The planned residence is a three bedroom, two bathroom, house. A house is being moved onto the property and placed on a foundation that is then to be finished for the level of the unit. The lot is approximately 3.6 acres in size. There is an existing well on the property. This site is in the Basalt Area on the old Highway 82 road, overlooking the highway and the Roaring Fork River. It consists of a relatively steep hillside sloping to shallower grades toward the bottom. Clumps of oak brush trees cover the hillside. The ground surface, which appears natural in the proposed area of the absorption field, slopes to the South at -W25 gra . The surface of the ground is cluttered with cinders and stones or baaan. There is an large dry gulch draining the property ab , 0 feet the percolation test hole location. 3 7q )- ?6` P.O.

The excavation revealed that bedrock was not present within 10 feet of the surface of the ground. No groundwater or evidence of groundwater was encountered in the excavation_ The soils on the property consisted of 8 inches of brown sandy loam overlaying a grayish brown stony loamy sand with some gravel and flagstone fragments and cobbles, three or four inches to over two feet in diameter encountered below the depth of four feet. The subsoil was relatively more sandy toward the bottom of the profile pit excavation. The subsurface soil conditions were evaluated with the standard percolation test procedures at the approximate location shown on Figure 1. The subsoil, in which the percolation testing was done, consisted of a loamy sand. These soils were well consolidated, and showed little tendency to swell. The test hole was prepared by hand - digging a small hole, eighteen inches deep, in the bottom of an 8 112 foot deep backhoe excavation. Gravel was placed in the test hole. Percolation testing was performed in the proposed absorption pit location. The percolation hole was pre-soaked the morning before testing. Water was added to the test holes at a regular intervals of approximately one hour throughout the day. A total of twenty five gallons was added to the test hole the day the test was conducted. Presoaking, therefore, was accomplished for a sufficient time before beginning the percolation test. The results of the percolation testing are presented in Table 1. These results indicate the subsoil in the the absorption pit has an average percolation rate r inch at the botto of the pit excavation. The soil conditions encountered are acceptable for a conventional infiltration design for the on -site sewage system. IlAinlrrwm Eagle County Reouirertts: The minimum Eagle Cuirements for this installation are based on a system loaded at an aver a �Wr:j llons per day. This flow would require a s®ptic tank of 1000 gallons and a minimum of 500 square feet of standard seepage pit. b�/1ylyy� l�l:lb �a���rh6 BOB NELSON, NEWS,LTD PAGE 04 y i Walker Residence Soils Evaluation and percolation Test for Individual Sewage Disposal System Design 08/29f94 Page 3 Recommended 0n:2itg,.Waj water Disoasal Design: Given the constraints of the site, it would appear that the best solution for the septic system design would be a seepage pit located on the hillside below the building site and west of the driveway. The seepage pit construction will minimize surface disturbance, fit into the limited area available, and take advantage of the more porous and permeable soils below the surface. We, therefore, recommend that the septic system design incorporate the use of a seepage pit- _Tb9 seexsae-wquiired to pravide a sideMrall area of 1 s uar� feet for each 150 gallons of wastewater flow to be absorbed. This would allow the axca—va-Fedseepage pit-a-bou 13' x 13' x 19 deep o provic�he required absorption area. Limitations: This report has been prepared according to generally accepted practices in this area for use for sewage disposal design purposes. The conclusions and recommendations submitted in this report are based upon data obtained from our site visits at the location indicated. There is some possibility that the nature and extent of variations in the subsurface soils across the site may not have been evident at the time of this investigation, and may need additional evaluation if further excavation reveals conditions different from those described_ This office should be advised of any unusual situations as soon as possible so that we may reevaluate our recommendations_ If you have questions or if we may be of further assistance, Y 4 Y please call the office.

The property is in the Basalt Area on the old Highway 82 road, overlooking the highway and the Roaring Fork River. it consists of a relatively steep hillside sloping to shallower grades toward the bottom. Clumps of oak brush trees cover the hillside. The ground surface, which appears natural in the proposed area of the absorption field, slopes to the South at a 20 to 25% grade. The surface of the ground is cluttered with cinders and stones of basalt, making shallow absorption trench installation difficult. There is a large dry gulch draining the property about, 60 feet East of the seepage pit location, and much of the rest of the terrain is undulating and uneven. There is a cut bank to the South of the building site and along Highway 82, approximately 18 feet high. The soil profile pit, excavated earlier within an area considered suitable for an on -site wastewater disposal system, revealed that no groundwater was encountered in the excavation and that the soils were permeable to a depth of approximately ten feet. The ground water elevation is assumed to be river level and approximately thirty-one feet below the surface of the ground in the area of the septic system as shown on the tpography map of the site, providing the ten feet of soil above the expected water table level below the bottom of the pit. The subsoil was relatively mores sandy toward the bottom of the profile pit excavation. The soil conditions encountered are considered acceptable for a conventional infiltration design for the on -site sewage system with a percolation rate of 9 minutes per inch. The minimum Eagle County requirements for this installation are based on a system loaded at an average of 450 gallons per day. This flow would require a septic tank of 1000 gallons and a minimum of 750 square feet of standard seepage pit. P.O. Box 6%1 Snowmaw Village, CO.81615 Office (303) 923.

I dUJ'J2J21bb BOB NELSON, NEWS, LTD PAGE 03 Walker Residence Individual Sewage Disposal System Design November 5, 19cA Page 2 Given the constraints of the site, it still appears that the best solution for the septic system design would be a "seepage pit located on the hillside below the building site and West of the driveway. The seepage pit construction will minimize surface disturbance, fit into the limited area available, and take advantage of the more porous and permeable soils below the surface. A seepage pit offers several advantages over trench construction. These include: 1) Minimize the surface disturbance and amount of vegetation that must be removed. 2) Eliminate the need to provide shallow trenches on contour in the surfical soils containing a large portion of large, loose rock. 3) Eliminate the need for the trenches to be dug very deep to provide a level bottom in all of thebuilding site area where the terrain is uneven and undulating. We, therefore, recommend that the septic system design incorporate the use of a seepage pit. The seepage pit is required to provide a sidewall area of 165 square feet for each 150 gallons of wastewater flow to be absorbed. This would allow the excavated seepage pit about 15' x 15' x 13' deep to provide the required absorption area. Our recommendations have been prepared according to generally accepted practices in this area for use for sewage disposal design purposes. The conclusions and recommendations submitted in this report are based upon data obtained from our site visits at the location indicated.

Box 10255 Aspen, CO 81612 Subject: Individual Sewage System Construction for a 3.6 acre lot, A parcel of Land in Tract 61, Section 12, T8S, R87W of the 6th P.M., numbered as 22501 Old State Highway 82 Dear John, As required by Section 4.03.15 of the Eagle County Environmental Health Department Individual Sewage Disposal Systems regulations, this letter presents the results of an installation observation of an onsite sewage disposal system at the subject site. The system was designed to Eagle County criteria and inspected on November 22, 1994. The system, installed by Dreager Excavating, included the installation of a seepage pit with an effective area of 832 square feet of sidewall absorption area. The seepage pit was constructed of three-foot concrete rings to create the void in the center and gravel filling the space between the rings and the sidewalls of the pit excavation. The top of the seepage pit was covered with foundation drain fabric. One 1250 gallon two compartment, precast, concrete septic tank was installed between the residence and the seepage pit. The components of the onsite wastewater system were installed in general conformance with the plants and specifications, Our recommendations have been followed and meet the regulatory requirements and generally accepted practices in this area for use for sewage disposal construction. Enclosed is a final drawing of the location and a final detail of the specifications for the septic system. If there are any questions or if we may be of further assistance in the future, please call the office. Sirrc;erely, r Robert F. Nelson, R. E. H. S.
