Box 10147 Aspen, CO 81611 Subject: Individual Sewage System Design for the Rolles Residence, Lot 10, East Owl Creek Subdivision, numbered as 1130 Cluny Road Dear John, As requested, Nelson Environmental and Wastewater Solutions, Ltd., has performed a soils study and percolation testing for the design and construction of a septic system for the proposed residence at the subject site. This letter details our design recommendations and some thoughts on alternatives. Proposed Construction and Building Site: The residence is to be a three bedroom, three bath home with an additional two one-half bathrooms and a second laundry. The building is proposed to be a one to two story home stepped up the slope. .Minimum Pitkin County Requirements: The percolation rates measured were averaged at an average of 12 minutes per inch. However, the underlying bedrock below the soils is considered an unsuitable condition for conventional on-site wastewater disposal systems. The minimum Pitkin County requirements for this installation are, therefore that a site-specific design be done by a Registered Professional Engineer. The basis of the design is calculated on an average daily sewage flow to the systems of approximately 450 gallons per day. Recommended On-site Wastewater Disposal Design: While we are not attempting to complete the site specif is design of the engineering firm, there are several items which we feel are important to consider and incorporate into the system. 1) Although not required, we have selected to divided the flow into a black water fraction of 330 gallons per day and a gray water fraction from the laundries of 120 gallons per day. It is then possible to use a combination of an engineered sand mound for the wastewater generated from the residence and a more conventional, shallow gray water bed for the laundry that maintains a two foot depth of suitable soil from the bottom of the bed to the fractured bedrock. Rolles Residence Soils Evaluation and Tests for Individual 1130 Cluny Road July 20, 1993 Page 2 P- rcolation Sewage System D_ The soil texture encountered in the percolation test holes was the same as in the profile excavation, a silty loam about 18 to 30 inches thick and a sandy clay loam to 4 feet in depth. The subsurface soil conditions were evaluated with the standard percolation test procedures at the approximate location shown on Figure 1. The set of test holes was hand dug to a depth of two feet to adjust for the proposed engineering design and shallow, fractured bedrock conditions. Four inches of gravel were placed on the bottom of each hole. Percolation Testing: Percolation testing was performed in the proposed engineered mound area Northeast of the residence. This testing was performed in three shallow holes excavated with hand tools to a depth of twenty- four inches. The percolation holes were pre-soaked by adding water the evening before and at intervals during the day, before beginning the percolation test in the late evening. The results of the percolation testing are presented in Table I. These results indicate the silty loam soils and fractured shale claystone have an average percolation rate of 12 minutes per inch, a satisfactory percolation rate under Pitkin County criteria. Limitations: This report has been prepared according to generally accepted practices in this area for use for sewage disposal system 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 we may reevaluation of our recommendations. If you have questions or if we may be of further assistance, please call the office. Sine el,y, Robert F. Nelson, R.E.H.S. President cc: Banner Engineering Revie ed By: enneth J. Brotsk P. E.

We conducted this study according to Section 4-5 of Pitkin County Regulations Individual Sewage Disposal Systems on July 9 and July 20, 1993. We have based our recommendations on the subsurface conditions encountered. Please furnish this letter to Banner Engineering and the Aspen/Pitkin Environmental Health Department at your earliest convenience to obtain a permit to construct this individual sewage system. Proposed Construction: The planned residence is a three bedroom, additional two one-half bathrooms and property is served by a subdivision water into the shallow alluvium along the creek Road from this subdivision. The lot is size. Site Conditions: three bath home with an a second laundry. The supply from wells drilled bed and across Owl Creek approximately 5 acres in The site is a platted lot within the East Owl Creek Subdivision. It is located on a east facing sides lope a small draw to the East. Most of the lot is forested with aspen trees and native vegetation. The ground surface in the proposed area of the absorption field, appears natural and slopes to the Northeast at a grade of 12% to 20%. Subsurface Conditions: The soi 1 prof i le pits and borings were approximately within 10 feet of the proposed septic system absorption areas. All revealed that the soils within the building envelope portions of this lot are a silty loam topsoil overlaying a sandy clay loam to a depth of two to four feet. At a depth of three to four and one half feet fractured and weathered claystone bedrock was encountered. This bedrock became harder and more consolidated with depth, but could still be excavated with equipment. Rolles Residence Design Recommendations July 20, 1993 Page 2 2) The flows would require a septic tank of 1000 gallons minimum volume, and a minimum of 460 square feet of engineered mound bed for the black water fraction. The gray water system would consist of a 750 gallon septic tank and minimum of 235 square feet of seepage bed. Approximately 140 square feet of seepage bed constructed with "Infiltrator" leaching chamber units could be substituted for the gray water system bed. 3) It is advisable to excavate the gray water bed as shallow as possible, to a depth of no more than two and one-half feet. 4) It is advisable to use dosing siphons to equalize the flow to the engineered mound bed. 5) There is the potential for a perched water table during heavy precipitation or seasonal runoff in these site conditions. An underdrain system is recommended at the uphill end of each septic system disposal bed. This provides a drain to prevent buildup of water and a seasonally saturated condition within and under the systems. 6) We recommend using a 1250 -gallon concrete septic tank with manhole lids and risers to the surface of the ground for the blackwater system. The extra detention time provided by the larger septic tank volume is beneficial to the system operations when peak or surge loading occur. Therefore, the suggested design incorporate the alternatives listed below. We recommend that the final septic system configuration consist of three ETA trenches, each 100 feet long.
