The study was conducted in accordance with our agreement for geotechnical engineering services to you dated July 21, 2003. The data obtained and our recommendations based on the proposed construction and subsurface conditions encountered are presented in this report. Proposed Construction: Design plans for development of the lot were conceptual at the time of this study. We understand that the proposed residence will be a single family residence with a full basement level located in the area of the exploratory boring and pits shown on Figure 1. Ground floors could be slab -on -grade or structural above crawlspace. Cut depths are assumed to range between about 4 to 10 feet. Foundation loadings are assumed to be relatively light and typical of the proposed type of construction. The septic disposal system is proposed to be located northeast and downhill of the proposed residence. The irrigation ditch is proposed to be relocated around the building footprint. If building conditions or foundation loadings are significantly different from those described above, we should be notified to re-evaluate the recommendations presented in this report. Site Conditions: The lot was vacant at the time of our field exploration and is located to the south and uphill of the subdivision road which crosses the north end of the lot. The building area is accessed via a rough graded dirt road. A live irrigation ditch flows northeast through the proposed building footprint and continues along the east side of the building envelope. The ground surface in the building envelope is irregular but mostly flat with typically a moderate slope down to the northeast. Vegetation consists Parker 303-841-7119 ® Colorado Springs 719-633-5562 9 Silverthorne 970-468-1989 Mandron Group August 6, 2003 Page 2 of grass and weeds with sage and oak brush. Scattered cobbles and boulders were observed on the ground surface. Subsurface Conditions: The subsurface conditions at the site were evaluated by drilling one exploratory boring, and excavating two exploratory pits in the building area and one profile pit in the septic disposal area at the approximate locations shown on Figure 1. The logs of the boring and pits are presented on Figure 2. The subsoils encountered, below about 1 foot of organic topsoil, consist of a shallow depth of stiff to very stiff sandy clay with scattered rock fragments up to cobbles size overlying dense gravel, cobble and boulder size rock fragments in a sandy clay matrix down to the maximum explored depth of 6 to 8 feet. Results of swell -consolidation testing performed on relatively undisturbed samples of the upper sandy clay, presented on Figures 4 and 5, indicate low compressibility under existing moisture conditions and light loading and high expansion potential when wetted. Results of a gradation analysis performed on a sample of the underlying gravel and cobble rock fragments (minus 6 inch fraction) obtained from Pit 2 are presented on Figure 6. The laboratory test results are summarized in Table 1. No free water was observed in the boring or pits at the time of drilling or excavation and the soils were slightly moist to moist. Foundation Recommendations: Considering the subsoil conditions encountered in the exploratory boring and pits, and the nature of the proposed construction, we recommend spread footings placed on the natural coarse granular subsoils and designed for an allowable soil bearing pressure of 3,000 psf for support of the proposed residence. Footings may need to be designed for a minimum dead load if expansive soils are encountered in footing areas. Due to the variable nature and settlementfheave potential of the subsoils, bearing conditions in footing areas should be evaluated at the time of construction. Footings should be a minimum width of 16 inches for continuous walls and 2 feet for columns. The upper clay soils and loose disturbed soils encountered at the foundation bearing level within the excavation should be removed to expose the undisturbed natural soils. Exterior footings should be provided with adequate cover above their bearing elevations for frost protection. Placement of footings at least 42 inches below the exterior grade is typically used in this area. Continuous foundation walls should be reinforced top and bottom to span local anomalies such as by assuming an unsupported length of at least 10 feet. Foundation walls acting as retaining structures should be designed to resist a lateral earth pressure based on an equivalent fluid unit weight of at least 55 pcf for the on-site granular soil as backfill. Rock larger than about 6 inches, topsoil and clay soils should not be included in the backfill. Job #103 469 C�teCh I�� 0 Mandron Group August 6, 2003 Page 3 Floor Slabs: Due to the variable settlement/heave potential of the subsoils, the feasibility of slab -on -grade construction should be evaluated at the time of construction. Structural floors over a crawlspace are commonly used where expansive subgrade soils are encountered. The following recommendations should be followed if slabs -on -grade are proposed. To reduce the effects of some differential movement, interior slabs should be separated from all bearing walls and columns with expansion joints which allow unrestrained vertical movement. Floor slab control joints should be used to reduce damage due to shrinkage cracking. The requirements for joint spacing and slab reinforcement should be established by the designer based on experience and the intended slab use. A minimum 4 -inch layer of free -draining gravel should be placed beneath basement level slabs to facilitate drainage. This material should consist of minus 2 -inch aggregate with less than 50% passing the No. 4 sieve and less than 2% passing the No. 200 sieve. All fill materials for support of floor slabs should be compacted to at least 95% of maximum standard Proctor density at a moisture content near optimum. Required fill can consist of the on-site granular soils devoid of vegetation, topsoil, and rock larger than about 6 inches or road base. Underdrain System: Although free water was not encountered during our exploration, it has been our experience in the area that local perched groundwater can develop during times of heavy precipitation or seasonal runoff. Frozen ground during spring runoff can create a perched condition. We recommend below -grade construction, such as retaining walls, crawlspace and basement areas, be protected from wetting and hydrostatic pressure buildup by an underdrain system. The drains should consist of drainpipe placed in the bottom of the wall backfill surrounded above the invert level with free -draining granular material. The drain should be placed at each level of excavation and at least 1 foot below lowest adjacent finish grade and sloped at a minimum 1 % to a suitable gravity outlet. Free -draining granular material used in the underdrain system should contain less than 2% passing the No. 200 sieve, less than 50% passing the No. 4 sieve and have a maximum size of 2 inches. The drain gravel backfill should be at least 11/2 feet deep. Surface Drainage: The following drainage precautions should be observed during construction and maintained at all times after the residence has been completed: 1) Inundation of the foundation excavations and underslab areas should be Job #1 03 469 0 Mandron Group August 6, 2003 Page 4 avoided during construction. Drying could increase the expansion potential of the clay soils. 2) Exterior backfill should be adjusted to near optimum moisture and compacted to at least 95% of the maximum standard Proctor density in pavement and slab areas and to at least 90% of the maximum standard Proctor density in landscape areas. Free -draining wall backfill should be capped with about 2 feet of the on-site, finer graded soils to reduce surface water infiltration. 3) The ground surface surrounding the exterior of the building should be sloped to drain away from the foundation in all directions. We recommend a minimum slope of 12 inches in the fust 10 feet in unpaved areas and a minimum slope of 3 inches in the first 10 feet in pavement and walkway areas. A swale may be needed uphill to direct surface runoff around the residence. 4) Roof downspouts and drains should discharge well beyond the limits of all backfill. 5) Landscaping which requires regular heavy irrigation should be located at least 10 feet from the building. Consideration should be given to the use of xeriscape to limit potential wetting of soils below the building caused by irrigation. Percolation Testing: Percolation tests were conducted on July 25, 2003 to evaluate the feasibility of an infiltration septic disposal system at the location designated by Mr. Mandich. One profile pit and three percolation holes were dug at the locations shown on Figure 1. The test holes (nominal 12 inch diameter by 12 inch deep) were hand dug at the bottom of shallow backhoe pits and were soaked with water one day prior to testing. The soils exposed in the percolation holes are similar to those exposed in the Profile Pit shown on Figure 2 and consist of dense gravel and cobble rock fragments in a sandy clay matrix. Percolation testing indicates infiltration rates of 120 to 240 minutes per inch. The percolation test results are presented in Table 2. A civil engineer should design the infiltration septic disposal system. Limitations: This study has been conducted in accordance with generally accepted geotechnical engineering principles and practices in this area at this time. We make no warranty either express or implied. The conclusions and recommendations submitted in this report are based upon the data obtained from the exploratory boring and pits located as shown on Figure 1, the proposed type of construction and our experience in the area.

Heller/Moss 1041 Hazard Review & Lot Line Adjustment. Parcel ID # 2465,331-01-005 The Aspen/Pitkin Environmental Health Department has reviewed the details of the Heller/Moss application under the -authority of the Pitkin County Code, Title II,- Land Use Code and has the following comments. ADEQUATE PROVISIONS FOR WATER NEEDS: Sections 2-170 and 3=110.4:: 'It Is the policy of the county to Insure the availability of awater supply of adequate quality, quantity, pressure and dependability for fire protection and support of a proposed land use prior to approval of the use. The County shall require land uses'to hook up to existing public rsystems ,If service is available.•.. - This Department needs adequate information on the quantity/quallty of water available. This can be done from. tests of wells present on-site by a water engineer's or well driller's report. The applicant.must ensure that the water quality Is acceptable by having it tested by'a lab .such as the Snowmass water and Sanitation District,or Aspen Consolidated Sanitation District. water of acceptable quantity has been obtained in other lots In this area. Before a septic permit can .be issued, the well must be drilled to assure that setback requirements from the well to. the sewage disposal system can tie maintained. Pitkin County Land use Code requires that the weir site be within the .building envelope.. It is, recommended that low water landscaping (xeriscaping) be used and that,the timing of.any sprinkler systems be decreased for low water. plants. The Colorado State University cooperative Extension office can be contacted for more Information on xe.riscaping. t A condition of approval for -this application is the receipt of information documenting that the locations of the wells meet setback requirements and can be placed within 'the building envelopes and that quantity/quality . of the well water are adequate. 'Without meeting these requirements; sewage disposalsYstem permits and building permits. can not be issued. 1 0 ■ SEWAGE TREATMENT AND COLLECTION: Sections 2-180 and 3-110.5: 'Itis the policy of the County to ensure that adequate sewage treatment fwiitles are available to serve existing and new developments. Public and. private Sewage disposal systems and connections to Such systems Shall comply wlth the sewage disposal guidelines of Pitkin County's Individual Sewage Disposal System Regulation' Lots in the SopriS Mountain Ranch area are served by individual -sewage disposal systems: All such systems installed within Pitkin County require septic permits issued by the Environmental Health Department, and must comply with the County's sewage disposal regulations. To receive a septic permit, the applicant will need to submit a. septic permit application and appropriate fee with.a completed soil data information including percolation test results•and profile hole information as'weli as site piamand building floor plans... it must be, possible to design an adequate sewage disposal system before a, building perniit.can -be issued.' The Aspen/Pitkin Environmental. Health Department will design the system for the applicant as part of the permit fee, .if an engineered system is not required...- We equired.•.We will do a site visit, advise the applicant about the best location for the system and provide a system design. We will determine if an engineered system is.needed based on soiltest results. -An engineered system is required if any one.of the following conditions exists: a percolation rate faster than 5 mpi or slower than 60 mpi; maximum seasonal level of the he table or bedrock less than four feet below the bottom of the proposed absorption system; or a slope in excess of 30%.. Prior to initiating any tests at the site, the applicant should Contact this office. 'No percolation test resUlts.were provided, so it is unknown at..this time what types of. systems will be required. it is likely, that sewage disposal systems can be installedon these lots, however, the applicants should be aware that there are some lots in the Sopris Mountain Ranch area.that have had to- have engineered systems installed. Site specific soil data will have to be obtained, and the applicants will need to adhere to. - minimum horizontal setback requirements for placement of sewage disposal system components. A setback chart has been Included with these comments. They -will need . to: locate the leach field sites.a minimum of 100 feetfrom their wells and from any-. neighboring wells. 'Depending on the size of the homes and the number of -bedrooms _. or rooms of similar size, there is the possibility that the .distances will have to be greater than 100 feet between wells.and sewage disposal systems. For. example,.a home :of. between 2,000 4 6,000 sq. ft. with 5.bedrooms or rooms of similar size will need to:be.at least 156 feet from any wells, The proposed building envelopes are large so there shouldn't.be a problem maintaining the required distances from _the.well and sewage disposal system components. Placement of the wells should be considered prior to drilling to insure that there will be no problems with maintaining these setbacks. 1 It is desirable to locate the system downhill from the house so that the systerp can operate by gravity:.. The leaching area itself should-be.on an area that is as level as possible. According to the information provided, the. building envelopes range...' M between 10 to 25% slopes. Since no soil absorption system shall be permitted in areas where the ground slope is in excess of 30% unless designed by an engineer, this Department may need sufficient information to document that the area for the sewage disposal systems) is not in excess of 30%. If the sewage disposal systems) is installed in separate trenches terraced down the slope, the system(s) should function properly. According to the information provided in the application, the lot line adjustment has created a new building envelope where the slopes are less.severe. From the standpoint of this Department, that has allowed for a more suitable location for a sewage disposal system to be installed. The area for the leach fields should be located in an area of no traffic, planted with dry land grass, and should not be watered. The applicants should refer to the Pitkin County Sewage Regulations for detailed information, or call our office to discuss this site. If the well permit states that the sewage disposal system must be of the non- evaporative type where the water is returned to the same stream system in which the well is located, a completely lined field, such as an evapo-transpiration bed, is not allowed unless the applicant contacts the Colorado Division of water Resources and a new well permit is in place or a plan of augmentation is created. A condition of approval for this application is the receipt and approval of the sewage disposal permits by the Environmental Health Department before building permits can be issued. The sewage disposal systems must be located within the building envelopes. WATER QUALITY IMPACTS: Sections 2-140 and 3-70.5 and 3-70.10: -It is the policy of the County to preserve and protect its present water resources, recognizing the County's semi -arid character and that significant transmountain and transbasin diversions and the vested rights of senior appropriators in the basin have materially curtailed the availability of an already scarce water resource. To this end it is the policy of the County that no land use be initiated which would adversely affect the quantity, quality. or accessibility of the County's water resources; or which would occur at the expense of established water -dependent agricultural activities; or which would result In increased saIinization of water resources, loss of minimum stream flows, further destruction of wildlife habitat, or major expenditures to reacquire or redistribute major water resources. It is also the policy of the County to maintain a natural vegetative buffer along its surface waters such that the surface and groundwaters of the area are not encroached upon by land uses or other human activities which could cause deterioration of water quality or impair the natural treatment processes provided by meadows and wetlands.' . The Environmental Health Department is charged with preserving and protecting the quality of Pitkin County's water resources. Since a large percentage of the population is dependent upon water from wells, elimination of groundwater pollution, and protection of aquifers and their drainage areas are of utmost importance. Surface water and groundwater contamination can also be caused by inadequate setback distances from sewage disposal systems to proximate wells, rivers, creeks, ponds, ditches and reservoirs. Minimum horizontal distances between components of a sewage disposal system and physical features must be in accordance with the Pitkin County Sewage Regulation. This Department reserves the right to require water quality sampling at the homeowner's expense. 123 A condition of approval for this application is that all setback distances be maintained between sewage disposal system components and wells, rivers, creeks, ponds, ditches and reservoirs. AIR QUALITY: sections 2-130 and 3-602: 'Only that development is permitted which will not contribute significantly to degradation of air quality. This project is not expected to contribute significantly to degradation of air quality in Pitkin County. Activities such as road building and landscaping require a Fugitive Dust Plan. This plan would need to include, but is not limited to, fencing, watering of haul roads and disturbed areas, daily cleaning of adjacent paved roads to remove mud that has.been carried out, speed limits, or other measures necessary to prevent windblown dust from crossing the property line or causing a nuisance, A condition should be approval by the Aspen/Pitkin Environmental Health Department of the fugitive dust control plan, containing enough measures to ensure that dust does not become a nuisance or blow onto adjacent property. The applicant must file a fireplace/woodstove permit with the Environmental Health Department before the building permit will be issued. The less densely populated parts of the county like Sopris Mountain Ranch may have two devices per building: a maximum of one wood burning fireplace and a second device which can be either a gas log fireplace or a certified.woodstove. In addition, unlimited numbers of decorative gas appliances are allowed. Coal may not be burned in any device. No wood burning device maybe installed in barns or agricultural buildings. A condition of approval for this application is the receipt and approval of the fireplace/woodstove permits by the Environmental Health Department before the building permits can be issued. CONFORMANCE WITH OTHER ENVIRONMENTAL HEALTH LAWS: section 2-70: "It is [Me policy of the County to ensure that no use or development of land is peryitted which is In violation of the laws of the County, the State of Colorado. or the United States of America.- This Department is not aware of any Issues lof concern regarding other environmental health laws. 3Li DRAWN 8 DESIGNED BY.
