The testing was done in addition to and in accordance with our agreement for professional services to Kaegebein Fine Homebuilding, dated January 21, 2014. A profile pit and three percolation test holes had been excavated by others at each test location shown on Figures 1 through 1 E. The subsoils exposed in the Profile Pits were variable and below the topsoil consisted of sandy silt and clay, silty sand and silty sand and gravel with cobbles to the bottom pit depths of 81/2 to 9 feet feet. No free water was observed in the pits and the soils were slightly moist to moist. Percolation test holes were hand dug in the bottom of shallow backhoe pits and soaked with water the day prior to testing. Percolation testing was conducted on April 4 and 8, 2014, by a representative of Hepworth - Pawlak Geotechnical, Inc. The percolation test results are summarized in Table 1 for each of the 6 locations. Based on the subsurface conditions encountered and the percolation test results, the tested areas should be suitable for a conventional infiltration septic disposal system. A professional civil engineer should design the onsite waste disposal systems. If you have any questions or need further assistance, please call our office. Sincerely, HEPWORTH - PAWLAK G Steven L.

The project site is shown on Figure 1. The purpose of the study was to develop recommendations for the foundation design. The study was conducted as additional services to and in accordance with our agreement for geotechnical engineering services to Kaegebein Fine Homebuilding, dated January 21, 2014. We previously conducted a rockfall risk assessment to a residence constructed on Homestead 1 and presented our findings in a report dated July 1, 2014. A field exploration program consisting of an exploratory boring was conducted to obtain information on the subsurface conditions. Samples of the subsoils obtained during the field exploration were tested in the laboratory to determine their classification and other engineering characteristics. The results of the field exploration and laboratory testing were analyzed to develop recommendations for foundation types, depths and allowable pressures for the proposed building foundation. This report summarizes the data obtained during this study and presents our conclusions, design recommendations and other geotechnical engineering considerations based on the proposed construction and the subsurface conditions encountered. PROPOSED CONSTRUCTION The proposed residence will be a 2-story, wood frame structure with a total living area of 5,750 square feet and ground floor over a 5'-6" deep crawlspace, and located as shown on Figure 1. As a result of a rockfall risk assessment to Homestead 1, the building location was moved to the southwest part of the building envelope to avoid potential rockfall impact and the original proposed building location was abandoned. The garage floor will be slab -on -grade. Grading for the structure will be relatively minor with cut depths up to about 6 feet. We assume relatively light foundation loadings, typical of the proposed type of construction. J'ob No. 114 019A eetech If building location, grading or loading information changes significantly from that described above, we should be notified to re-evaluate the recommendations presented in this report. SUE' ' CONCN[JAWNS The building site was vacant, irrigated pasture at the time of our field exploration. The proposed boring location had been staked by others near the center of the original building site. The ground surface slopes gently down to the southwest with about 2 feet of elevation difference across the proposed building footprint. Vegetation consists of field grass and weeds. FIELD EXPLORAT1[ON The field exploration for the project was conducted on April 3, 2014. One exploratory boring was drilled at the original building location shown on Figure 1 to evaluate the subsurface conditions. The boring was advanced with 4 inch diameter continuous 'fight augers powered by a truck -mounted CME-45I3 drill rig. The boring was logged by a representative of Hepworth-Pawlak Geotechnical, Inc. Samples of the subsoils were taken with 1% inch and 2-inch T.D. spoon samplers. The samplers were driven into the subsoils at various depths with blows from a 140 pound hammer falling 30 inches. This test is similar to the standard penetration test described by ASTM Method D-1586. The penetration resistance values are an indication of the relative density or consistency of the subsoils. Depths at which the samples were taken and the penetration resistance values are shown on Log of Exploratory l3ori.ng, Figure 2. The samples were returned to our office for review by the project engineer and testing. SUBSURFACE CON 'MEOWS A graphic log of the subsurface conditions encountered at the site is shown on Figure 2. The subsoils, below about %2 foot of topsoil, consist of 2 feet of medium, sandy silt and JobNo. t 14 019A G t i 3 ., clay overlying medium dense, silty sand and gravel with scattered cobbles and possible small boulders to the boring depth of 18 feet. Drilling in the coarse granular soil with auger equipment was difficult due to the cobbles and possible boulders and practical drilling refusal was encountered in the deposit. Laboratory testing performed on samples obtained from the boring included natural moisture content and gradation analyses. Results of gradation analyses performed on small diameter drive samples of the gravel soils (minus 1 % to 2-inch fraction) are shown on Figure 4. No free water was encountered in the boring at the time of drilling and the subsoils were moist. FOUNDATION BEARING CONDITIONS The sandy silt and clay soils, encountered to a depth of 3 feet at the boring, are compressible when loaded and wetted. Lightly loaded spread footings bearing on the silt and clay soils may be suitable for building support with a risk of foundation settlement. Alternatively, footings extended down and placed entirely on the underlying medium dense, silty sand and gravel soils would have a lower risk of settlement and building distress, and aye recommended for the building support. The boring was drilled at the original building location about 100 feet from the current building location and some variation in the subsurface profile should be expected. DESIGN RECOMMENDATIONS FOUNDATIONS Considering the subsurface conditions encountered in the exploratory boring and the nature of the proposed construction, we recommend the building be founded with spread footings bearing on the underlying coarse granular soils or compacted structural fill. Job No. 114 019A G8Stech The design and construction criteria presented below should be observed for a spread footing foundation system. 1) Footings placed on the relatively dense, natural granular soils should be designed for an allowable bearing pressure of 2,500 psf. Based on experience, we expect settlement of footings designed and constructed as discussed in this section will be about 1 inch or less. 2) The footings should have a minimum width of 16 inches for continuous walls and 2 feet for isolated pads. 3) Exterior footings and footings beneath unheated areas should be provided with adequate soil over above their bearing elevation for frost protection. Placement of foundations at least 42 inches below exterior grade is typically used in this area. 4) Continuous foundation walls should be reinforced top and bottom to span local anomalies such as by assuming an unsupported length of at least 12 feet. Foundation walls acting as retaining structures should also be designed to resist lateral earth pressures as discussed in the "Foundation and Retaining Walls" section of this report. 5) The topsoil, silt and clay soils, and any loose or disturbed soils should be removed and the footing bearing level extended down to the natural granular soils. The exposed granular soils in footing area should then be moistened and compacted. Compacted structural fill placed to reestablish design bearing level should consist of a relatively well graded granular soil compacted to at least 98% of standard Proctor density at near optimum moisture content, and extend at least 2 feet beyond the footing edges. 6) A representative of the geotechnical engineer should observe all footing excavations prior to concrete placement to evaluate bearing conditions. FOUNDATION AND RETAINING WALLS Foundation walls and retaining structures which are laterally supported and can be expected to undergo only a slight amount of deflection should be designed for a lateral earth pressure computed on the basis of an equivalent fluid unit weight of at least 55 pcf Job No. 114 019A tech 5 ._ for backfill consisting of the on -site soils. Cantilevered retaining structures which are separate from the residence and can be expected to deflect sufficiently to mobilize the full active earth pressure condition should be designed for a lateral earth pressure computed on the basis of an equivalent fluid unit weight of at least 45 pcf for backfill consisting of the on -site soils. All foundation and retaining structures should be designed for appropriate hydrostatic and surcharge pressures such as adjacent footings, traffic, construction materials and equipment. The pressures recommended above assume drained conditions behind the walls and a horizontal backfill surface. The buildup of water behind a wall or an upward sloping backfill surface will increase the lateral pressure imposed on a foundation wall or retaining structure. An underdrain should be provided to prevent hydrostatic pressure buildup behind walls. Backflll should be placed in uniform lifts and compacted to at least 90% of the maximum standard Proctor density at a moisture content near optimum. Backfill in pavement and walkway areas should be compacted to at least 95% of the maximum standard Proctor density. Care should be taken not to overcompact the backfill or use large equipment near the wall, since this could cause excessive lateral pressure on the wall. Some settlement of deep foundation wall backfill should be expected, even if the material is placed correctly, and could result in distress to facilities constructed on the backfill. The lateral resistance of foundation or retaining wall footings will be a combination of the sliding resistance of the footing on the foundation materials and passive earth pressure against the side of the footing. Resistance to sliding at the bottoms of the footings can be calculated based on a coefficient of friction of 0.40. Passive pressure of compacted backfill against the sides of the footings can be calculated using an equivalent fluid unit weight of 350 pcf. The coefficient of friction and passive pressure values recommended above assume ultimate soil strength. Suitable factors of safety should be included in the design to limit the strain which will occur at the ultimate strength, particularly in the case of passive resistance. Fill placed against the sides of the footings to resist lateral loads Job No. 114 019A caeca' should be compacted tout least 95% of the maximum standard Proctor density at a moisture content near optimum. FLOOR SLABS The natural on -site soils, exclusive of topsoil, are suitable to support lightly loaded slab - on -grade construction. To reduce the effects of some differential movement, floor 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 relatively well graded sand and gravel, such as road base, should be placed beneath interior slabs. This material should consist of minus 2 inch aggregate with at Ieast 50% retained on the No. 4 sieve and less than 12% 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 soils or a suitable imported granular material devoid of vegetation, topsoil and oversized rock. The upper silt and clay soils are highly moist and could require drying prior to use as backfill material. 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 also create a perched condition. We recommend below -grade construction, such as retaining walls and crawlspace, 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 Job No, 114019A Goa test 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 or drywell. Free -draining granular rnaterial 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 1 %Z 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 avoided during construction. 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. 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 6 inches in the first 10 feet in unpaved areas and a minimum slope of 2'A inches in the first 10 feet in paved areas. Free -draining wall backfill should be capped with about 2 feet of the on - site silt and clay soils to reduce surface water infiltration. 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 5 feet from foundation walls.

The BOCC considered this application at duly noticed public hearings on April 23 and June 11, 2014, at which times evidence and testimony were presented with respect to the application. 10. The BOCC finds that it is appropriate to grant an historic incentive of 1,500 square feet of floor area on the second floor of the Bourg Barn for a locker room in exchange for the 1,500 square feet previously granted for two accessory structures with bathing facilities, which are no longer proposed to be built. 11. The BOCC further finds that it is appropriate to approve the use of two TDRs for an additional 4,150 square feet of floor area for common non-agricultural facilities on the Agricultural Facilities Parcel — 900 square feet on the second floor of the Bourg Barn for a locker room and 3,250 square feet for the Pool House. 12. The BOCC further finds that the relocation of agricultural buildings — the equipment barn and hay barn — from the Agricultural Facilities Parcel to Homestead 1 is acceptable, as it avoids development within the debris flow on the Agricultural Facilities Parcel; the buildings will be clustered, are sited near the entry to the ranch, and will not create additional impacts on wildlife; and the square footage of the buildings will count against the 30,000 square feet of agricultural floor area approved pursuant to Resolution No. 112- 2005. 13. The BOCC further finds that it is appropriate to sterilize the Werk Cook Parcel from development in order to preserve important mule deer and elk habitat, and agrees in exchange to modify the 2011 Trail Easement as requested. Resolution No.0g32014 .Page 3 14. The BOCC further finds that it is appropriate to eliminate the new entry road that was constructed through the lower pasture and the proposed new road on the upper mesa to access Homesteads 6 and 7. Accessing Homesteads 6 and 7 from below rather than above will lessen disturbance the visibility of the driveways. Elimination of the lower road will maintain access around the perimeter of the main lower pasture with only ranch vehicle access through the center of the pasture. 15. The BOCC further finds that the proposed envelope on Homestead 8 to accommodate the on -site wastewater treatment system ("OWTS") avoids the 100' setback from Dry Woody Creek and is necessary to accommodate the OWTS for the proposed 13,000 square foot residence on Homestead 8. 16. The Board further finds that it is appropriate to amend the envelope on Homestead 9 to increase the setback from Dry Woody Creek from 20 feet to 50 feet. 17. The BOCC further finds that the other proposed amendments to building and development envelopes for landscaping, grading, ponds, driveways, utilities, ditch relocation and bridges are appropriate and comply with the applicable provisions of the Code. NOW, THEREFORE, BE IIT RESOLVED by the BOCC that it does hereby approve the proposed amendments, subject to the following conditions, which shall run with the land and be binding on all successors in interest: 1.

RESOLUTION OF THE BOARD OF COUNTY COMMISSIONERS OF PITKIN COUNTY, COLORADO GRANTING APPROVAL OF THE ASPEN VALLEY RANCH SPECIAL REVIEW, 1041 HAZARD REVIEW, CONCEPTUAL SUBMISSION AND GMQS EXEMPTION Resolution No. 0-2005 RECITALS 1. SGS-Ranch LLC ("Applicant") has applied to the Board of County Commissioners of Pitkin County, Colorado ("BOCC") for approval to develop 8 new single family residences on parcels ranging from 35 to 120 acres, to create a new 35+ acre parcel around the existing ranch house and a 35+ acie Agricultural Facilities Parcel that encompasses the existing agricultural buildings and affordable housing units. The Applicant is requesting approval for a total of 96,750 square feet of floor area for the development, with no more than 3 of the residences containing in excess of 10,750 and up to 13,250 square feet of floor area. The following approvals are requested and required: A. Rezoning of 245 acres of the ranch to Rural/Remote; B. 1041 Hazard Review and Conceptual Submission to establish building envelopes; C. GMQS Exemption and Special Review to establish the parcels as TDR receiver sites (for initial development rights and additional floor area); 2. The property is located on Upper River Road, and is more specifically described in Exhibit A. 3. The property is comprised of two separate parcels that contain a total of 731 acres. The property is zoned RS-20/PUD with the exception of approximately 2 acres of land that is zoned AH. 4. The Pitkin County Planning and Zoning Commission ("Commission") considered the proposed application at a regularly scheduled meeting on May 17, 2005, and recommended approval by a vote of 5-0. 5. The BOCC considered this application at duly noticed public hearings on July 27 and August 10, 2005, at which times evidence and testimony were presented with respect to the application. The BOCC reviewed and approved the Development Agreement on August 24, 2005. 6. The BOCC finds that the proposed building envelopes are located on slopes of less than 30% and avoid the 100 year floodplain and critical wildlife habitat areas; the wildfire hazard is rated as low to medium and can be mitigated; the debris flow hazard can be mitigated; 7. The BOCC further finds the development is consistent with the special review criteria for TDR receiver sites and caretaker dwelling units, and that the proposed development otherwise complies with the applicable provisions of the Land Use Code ("Code"). 8. The BOCC further finds that an extended vested right of 15 years is appropriate because the proposed development promotes the public benefit in a manner consistent with, and which promotes the policies and requirements contained in the Code. NOW, THEREFORE, BE IT RESOLVED by the BOCC that it does hereby approve the Aspen Valley Ranch 1041 Hazard Review, Conceptual Submission, Special Review and GMQS Exemption, subject to the following conditions, which shall run with the land and be binding on all successors in interest. 111 SILVIA DAVIS PITKIN COUNTY CO 516266 Page: 1 of 10 10/14/2005 02:20f R 0.00 0 0.00 1 Resolution No. /M--2005 Page 2 1.

This tank will be supplied water from an alluvial well field located on the property. This well field is located within Area "A" of the Basalt Water Conservancy District. A well was drilled in December, 2013 during low groundwater conditions and a long term pump test was conducted. The well is an excellent well with a sustained pumping rate of at least 35 g.p.m. A preliminary water quality test shows the well meets all Safe Drinking Water Act parameters (see attached Preliminary Report). A second well will be developed within the designated well field for system redundancy. 1'VATERLAW rAT ItI('K 1 MILLER I KROPF 1 NOTE) Adequate Water Supply Memo Central Water System February 3, 2014 Page 2 Because the well field is located within Area "A", well permits are covered under the Basalt Water Conservancy District's approved exchange plan providing a legal water supply for the well depletions. In addition, Applicant is the owner of the several approved Water Court legal water supply plans (plans for augmentation). Specifically, the following plans were decreed: Case Nos. 89CW291 & 95CW264: This case decreed a plan for augmentation for the Aspen Valley Ranch (and what is now Aspen Valley Downs) utilizing the Red Canyon Spring Well, Underwood Well No. 1, and Underwood Well No. 2 as sources of supply for up to eight affordable housing units and twelve single family units. Augmentation supplies ate provided by historic consumptive use dry -up credit resulting from the cessation of irrigation of 2.0 acres under the Waco Ditch and 2.7 acres under the Salvation Ditch as non -irrigation releases from the Underwood Pond on the AVR Property. Subsequently, in Case No. 95CW264 additional structures were augmented. Case No. 00CW278: This case decreed a plan for augmentation for the Aspen Valley Ranch for additional demands. Augmentation supplies ate provided by historic consumptive use dry -up credit resulting from the cessation of an additional irrigation under the Waco Ditch; non -irrigation season depletions are augmented via a Basalt Water Conservancy District Contract No. 382. While AVR AH, LLC is a beneficiary of the above plans for augmentation, the development proposal now will utilize an Area "A" Contract with the District.

Financial Spreadsheet — Not Applicable iii PROJECT SUMMARY Introduction This Report on Water System Technical, Managerial and Financial Capacity contains information concerning the proposed domestic potable water system to be constructed for the Aspen Valley Ranch development, in Pitkin County. This Report is being submitted to the Colorado Department of Public Health and Environment (CDPHE) in accordance with the requirements of the capacity development program per CRS §25-1=107, for its review and approval, to allow the Owner of this development, Aspen Valley Ranch AH LLC (ARV AH LLC), to proceed with construction and operation of the community water system. The Owners have directed that the water system be designed to accommodate more than 25 full-time residents. Therefore the system is to be managed as a Community Water System; this Report is submitted in accordance with CDPHE's New Water System Capacity Planning Manual. Proposed Development and Water Requirements The Aspen Valley Ranch contains approximately 900 acres, located in Pitkin County on the right bank of the Roaring Fork River, as shown on Drawing 1 of the Preliminary Engineering Report (PER), Appendix A. It is proposed to develop this Ranch for low density residential use. The system will serve Tess than 15 service connections (of any type), consisting of nine homesteads, a barn, club house, swimming pool building and the existing ranch center. System peak day potable water demands are estimated to be: o In Building O Irrigation o Fire Protection 11,150 gpd 32,000 gpd 1,200 gpm (all residences with sprinklers) A detailed breakdown of estimated water uses is presented in the Conceptual Water System Plan (Plan) included with this Report, as Appendix A. 1 Vicinity Map Figure 1 2 Proposed Water System The proposed treated water distribution system will include two wells, two booster pumps, disinfection, storage, distribution piping and fire hydrants. The overall system is illustrated and described on Drawing 1 in the attached Plan. Key system components are summarized following: Water Su I Wells Iwo wells will be drilled into the Roaring Fork Alluvium. Each well will have a sustainable capacity of 40 to 50 gpm. The water will be delivered to the treatment/pump station for disinfection using chlorination and UV treatment. The wells were located, designed, and tested by Resource Engineering. Their report and water quality analyses are included as Attachment B (also Table 1 in the PER). Treatment/Pump Station. The treatment/pump station will meter and deliver treated water to the distribution system using two 50 gpm high service pumps. A minimum pressure greater than 45 psi will be provided to all home sites. The station will also house the disinfection equipment and all electrical and controls. Distribution System. Water will be distributed via 10-inch, 8-inch and 4-inch mains, with all fire hydrants served by 6-inch branch lines. A 10-inch supply line will connect the distribution system to the water storage tank. As shown on Drawing 1 of the Plan, the higher elevation distribution 10-inch line will be looped for improved hydraulics and reliability. Due to the elevation difference of the development, some homesteads will require service line pressure reducing valves. Water Storage Tank. The water storage tank will be buried concrete and have a capacity of approximately 160,000 gallons. It will provide for operational storage, fire flow demands, and emergency storage. The tank is to be fitted with a hydraulic mixer, and operated so as to reduce average residence time and avoid stratification. Level controls will be included to control filling from the supply wells, with an overflow pipe in case of overfilling. Refer to Appendix C for the geotechnical investigation report detailing the site of the proposed tank. 3 TECHNICAL CAPACITY SOURCE WATER ADEQUACY Source of Water Supply The proposed development will be served by two wells, designed and located by Resource Engineering. Resource has addressed all necessary water rights issues and permitting. Table 1 in the Plan shows the raw water quality testing results of the wells, and is also included later in this Section. Reliability of Water Source Testing has shown that each well can supply a sustained flow of 40 to 50 gpm. See Appendix S. Adequate Protection The ground around the well heads is to be graded to drain away from the well so as to minimize the potential for surface water contamination. Cement grout was placed to seal the well casing pipe in accordance with State criteria. The well heads are adequately protected with a sanitary seal with (locking cap) located at least one foot above the ground surface at the well. There is no evidence of surface contamination of the well water from the water quality analyses that have been completed. The water level is over 73 feet from the surface and the wells are located over 500 ft. from the Roaring Fork River. The storage tank will be a 160,000 gallon completely buried concrete tank with secured access. Screens will be placed over the ventilation openings and overflow discharges, and frost -proof dampers will be installed in the air vents. In case of power failure or other emergency, the tank will be able to provide almost two weeks of in -building supply during non -irrigation periods. The booster pumping and chlorination equipment is to be located in a secured structure. Typically, the pumps will operate in a lead -lag fashion, providing a backup in case one pump is not operational. Sampling points are to be included in the treatment/pump station to monitor water quality. Provisions in the design will allow for a backup generator to be added in the future. 100-Year Flood Plain None of the water supply facilities are located in a 100-year flood plain. A FEMA map of well and pump station locations in relation to the 100 year flood plain is included along with the "100-Year Flood Plain Certification" in Appendix D. 4 INFRASTRUCTURE ADEQUACY Water Quality The Preliminary Report was prepared prior to receiving the well water quality test results. The results show that the raw water meets all State/EPA primary standards for inorganic chemicals. Results for this well, as well as comparable qualities previously determined for the Red Canyon Spring, for items of concern, follow: Well Raw Water Quality Test Results Contaminant Sodium Sulfate Nitrate Hardness New Well 5 mg/I 53 mg/I 0.5 mg/I 230 mg/I Red Canyon Spring, 3 mg/I 48 mg/I None 160 mg/I Standard 250 mg/I 10 mg/I Recommend 100 mg/I These results indicate minimal influence of Aspen or other upstream wastewaters (essentially a "virgin" supply). Hardness is of concern; there are no known health relationships — only with washing, bathing difficulty and plumbing encrustation. The EPA value for hardness is not mandatory or enforced. Note that it is not practicable to reduce hardness at the central plant since the system is to provide irrigation water — at relatively high demand rates. It is likely each customer's service will include a water softener for in -home water use (not including the fire suppression system). Condition of Infrastructure There is no existing water system infrastructure (except one new well). All components of the water system are to be new and are to be designed in accordance with CDPHE requirements and constructed by skilled contractors under the inspection of the system Owner, AVR AH LLC, and its engineering representatives. Disinfection of both wells, storage tank, equipment and pipelines will be in accordance with American Water Works Association standards as required by the contract documents for the various projects — and in accordance with design drawings and specifications approved by CDPHE 5 TECHNICAL KNOWLEDGE AND IMPLEMENTATION Operator Certification Per Certification of Water Treatment Plant and Wastewater Treatment Plant Operators, as amended 1996, Article 9 of Title 25, Part 100.8.2 the system, being of a capacity of Tess than 2 mgd and using groundwater with no additional treatment beyond chlorine disinfection, is anticipated to be a Class D facility. The system is required to be operated under the direct responsibility of a Class D certified plant operator. Operator Responsibilities The operator's responsibilities will include the following: ® Check of residual chlorine concentrations at the treatment/pump station and at the far end of the distribution system. Monitor amounts of hypochlorite on site and arrange for required deliveries from the chemical supplier. • Compliance monitoring, reporting and record keeping. Collect samples and arrange for annual water quality analyses. • Monitor service pressures, water meters, and tank and well water levels. Track equipment run times and perform regularly scheduled preventative maintenance. o Maintain appropriate spare parts on site for critical equipment. © Arrange for and oversee contractor services when needed. ® Operate distribution system valves in the event of a pipeline break or leak. Arrange for a pipeline contractor to affect repairs. ® Assist with locating buried distribution system pipelines for excavation contractors. ® Respond to alarm conditions and arrange for appropriate corrective actions. • Communicate with AVR AH LLC administration regarding equipment and support needs. Qualified maintenance personnel will be contracted with to assist the operator with major equipment overhaul and with electrical/control problems. AVR AH LLC will make arrangements with a local pipeline contractor to make emergency repairs to distribution pipeline breaks. 6 Operation and Maintenance Program AVR AH LLC representatives will compile manufacturer's literature describing in detail procedures for the proper maintenance and installation of major equipment. This information will be assembled in three-ring binders along with a written description of the operation procedures of the facilities. Two copies of each O&M Manual are to be compiled; with one to be maintained at the treatment/pump station and one at the AVR AH LLC office (Ranch Center). 7 MANAGERIAL PLAN System Ownership The water rights, water supply wells, storage tank, treatment/pumping station building, distribution piping, and all other appurtenant facilities and assets, including associated property rights are owned or directly controlled by Aspen Valley Ranch AH LLC. It is responsible for the design and construction of all wholesale water system facilities. The responsibility for the water system management and operation will initially belong to the ARV AH LLC, and it will obtain the services of a certified plant operator for the day to day management and operation. ARV AH LLC will assume full responsibility after a sufficient number of houses have been constructed to support the administrative responsibilities and costs of the system. ARV AH LLC responsibilities will include water usage accounting, billing, and payment of system operating expenses (e.g., electrical, insurance, laboratory, contract operator fees, etc.). (No meters are being installed?) It will also be responsible for compliance with the requirements of regulatory agencies for items such as safety, building codes, building permits, etc., as specified by 3.1 of the Design Criteria for Potable Water Systems. The responsibility for the maintenance of disinfection residuals and sample collection as required by the Colorado Primary Drinking Water Regulations will be that of the system operator. The operator and ARV AH LLC are expected to obtain the services of qualified electricians, plumbers, pump installers, and equipment service organizations as may be required to assist with maintenance of the system. System Operation and Management As noted previously, it is anticipated that the system will be a Class D facility and operated under the direct responsibility of a minimum Class D certified plant operator. Startup and Operating Procedures Prior to the beginning of system operations, the tank and pipeline contractor will disinfect the system to AWWA specifications as defined in the Design Criteria for Potable Water Systems. A 10% sodium hypochlorite solution will be mixed with water in the chemical feed pump solution tank. The initial mixture will contain ten gallons of water for each gallon of 10% sodium hypochlorite. The chemical feed pumps will be primed and connected to the injectors. Each well pump control will, in turn, be switched to the on or manual position and the operation of the well and chlorinator will be verified. The chlorine in the supply line to the tank will be monitored. The stroke and frequency controls will be adjusted on each chemical feed pump to obtain a 1.5 mg/I total chlorine reading. The pump controls will then be set to automatic operation and the pumps will alternate at each pump cycle. 8 A log of well water meter readings, chemical feeder settings, chlorine solution concentration and solution tank levels will be kept. After the tank has filled, the shutdown of the pumps and chlorinators will be verified. The pressure pump controls will be switched to automatic operation and the operation verified. Pressure pump cut - in and cutout pressures will be adjusted to provide adequate system pressure. System hydrants will be flushed and chlorine residuals monitored at the remote ends of the system. The contract operator is expected to be present at the startup of the water system and will perform the items noted in Startup and Operating Procedures above. As -built drawings and equipment manuals will be available on site. Routine Maintenance Operation and maintenance will include regular chlorine residual monitoring in the distribution system. Logs of water production, hypochlorite usage, and operational changes will be kept by the operator. Hypochlorite solution tanks will be refilled as required. System maintenance will include annual flushing of fire hydrants and lubrication of pumps as specified by the equipment manufacturers. Chemical feed pump suction lines, discharge lines and injectors will be serviced and/or replaced as necessary to provide for proper flow of the sodium hypochlorite solution. Sampling and Analysis Program A water sampling and analysis program consistent with the Colorado Primary Drinking Water Regulations and directives from the Water Quality Control Division will be instituted when a PWSID is assigned. Safety NIOSH compliant protective devices including gloves and a face shield will be provided in the treatment/pump station due to the sodium hypochlorite being stored. The local fire department will be notified of the chemicals used or stored onsite. Emergency Management Plan In the event of an emergency, ARV AH LLC or its designated representative will contact the system operator. The operator and the ARV AH LLC representative will discuss the emergency and decide on a course of action. The ARV AH LLC in cooperation with the operator would obtain the services of leak detection, water line excavation, plumbing and/or electrical contracting organizations, as needed. In the event of a major water line leak, the operator would consult the as -built system drawings and close the appropriate system valves to limit system water loss until the leak is repaired. 9 During the peak month of usage at full build -out and no reduction in irrigation, the 160,000 gallons of storage tank capacity can supply water to the system for approximately 2 days without additional water from the wells. No standby generator is envisioned during the initial system design; however provisions to add a generator will be incorporated into the system design such that the ARV AH LLC could quickly and economically add a generator if it determines there is a need. Operations and flllaintenarnce Manual An operations and maintenance manual, following the minimum outline from the State of Colorado New Water System Capacity Planning Manual, will be completed and made available to the water system administrator, Owner and to the certified water treatment plant operator. The manual will be completed and placed in service within three months after receiving a PWSID. 10 FINANCIAL CAPACITY Capital and 0 IUl Cost Responsibility All capital costs for construction of the water system facilities are being borne by the developer, ARV AH LLC on a cash basis (no debt). It will also cover the full costs of operating and maintaining the system. The ARV AH LLC will have the ability to finance the expected annual costs to operate and maintain the system. Credit Worthiness The ARV AH LLC is financially healthy. It has access to private capital sources to finance the water facilities. Fiscal Management and Controls This is to be a privately owned system, serving only customers related to the ARV AH LLC. No form of water service charges or tap fees are contemplated. 11 ■■■■■RESOD RE ■■■■■ NGINEERING I N C. Kevin Patrick, Esq Patrick Miller Kropf & Noto, PC 229 Midland Avenue Basalt, Colorado 81621 February 21, 2014 RE: AVR AH, LLC— 180 W Pasture Lane Well Pumping Test and Water Quality Analysis Dear Kevin: At the request of AVR AH, LLC, Resource Engineering Inc. (RESOURCE) analyzed the water quantity and quality for a new well located at 180 W Pasture Lane Woody Creek, Colorado. The pumping test for the well was conducted on January 14th through 15th, 2014, under the direction of RESOURCE. The data for the pumping test was collected by Ray s Well Done Pump Service, LLC (Ray's) and RESOURCE. A water sample from the well was obtained on January 14th, 2014 and submitted to National Testing Laboratories, Ltd. for analysis. SUMMARY The 180 W Pasture Lane Well has a valid monitoring well permit (Permit No. 293077) issued by the Division of Water Resources. The monitoring well permit allows for drilling the well, testing the yield and sampling the water quality. The well has an estimated long-term yield of approximately 40-50 gpm based on a 24-hour pumping test and recovery data. The well water quality shows hard water. However, the water sampled from the well is suitable for domestic uses. WATER WELL Well Construction The well was constructed on January 9, 2014, by Shelton Drilling. The well is approximately 105 feet deep and is constructed with 7-inch steel surface casing to approximately 63 feet. Perforated 5.5- inch steel casing was installed in the boulders, cobbles sand and gravel water producing zone from 80 feet to 105. At the time of the well construction, static water level was 75 feet from the top of casing (TOC) and the estimated well production was 15 — 20 gpm. Pumping Test A pumping test was conducted on January 14th through January 15th for the well. A Goulds 25GS15 pump was temporally installed for the test. The test was conducted for a full 24 hours using a step test approach. In the step test the discharge rate was started at an initial low constant rate of 15 gpm. The discharge rate was increased progressively higher to 20 gpm and then 30 gpm. Each step lasted approximately 30 minutes until the pump was at full capacity. Each step was of sufficient duration to allow dissipation of the well casing storage effects. Therefore, the aquifer was given enough time to stabilize. Data was collected approximately every minute during the step test. Once the pump was at full discharge and the water level was steady, measurements were taken every 10 minutes for the next 30 minutes and then at regular Consulting Engineers and Hydrologists 909 Colorado Avenue Glenwood 8pr'ir19s, CO 81 601 (970) 945-6777 Fax (9701 945-11 37 Kevin Patrick Page 2 February 21, 2014 intervals for the remainder of the test. A water meter was used to measure the instantaneous flow rate and the volume of water pumped throughout the pumping test. The initial water level was 73.5 feet below the TOC as shown in Figure 1. The initial pumping rate was approximately 15 gpm. The well had a total drawdown of approximately 1.1 feet as shown in Figures 2 and 3. At approximately 4 hours into the test the aquifer began to recharge. The recharge was mostly likely caused by the pump discharge being decreased for a short time or water infiltrating into the aquifer. The drawdown was projected assuming a continuous drawdown. The final water level at the end of the pumping part of the test was projected to be 74.6 feet, leaving approximately 25 feet of water above the pump intake. Over the 24-hour pumping period approximately 43,851 gallons was pumped, resulting in an average pumping rate of 30.2 gpm. Analysis Figures 2 and 3 shows the water level in the well dropped 0.1 ft. when the pump discharge was set at 15 gpm. Similarly when the discharge was set to 20 gpm, the water level dropped another 0.12 ft. When the pump was set at approximately 30.5, the well dropped another 0.4 ft. and then steadily declined until the water level was at 0.78 ft and then the aquifer slightly recharged. The small decline in the aquifer is attributed to the well being drilled in an unconfined alluvial aquifer. The aquifer is extensive and hydraulically connected to Woody Creek and the Roaring Fork River. Figures 4 and 5 depict the water level recovery in the well in the time after pumping ceased. T represents the total time since the pumping test started and T' represents the time since pumping stopped. The well reaches complete recovery at T/T' equals more than 2 (48 hr/24 hr), which means the well recovered faster than the rate at which the well was pumped. This indicates that, at the time of the test, the well completely recharged at a rate equal to or more than the 30.5 gpm average pumping rate. The data from the pressure transducer was analyzed to determine the Transmissivity (T) of the soil surrounding the well and the long term pumping rate (Q) of the well. The transmissivity is a measure of how much water can be transmitted horizontally to the well. The modified Theis method or the Cooper -Jacob Straight -Line Method was utilized to calculate transmissivity. This method was used to calculate the coefficient of transmissivity from the slope of a semi - logarithmic plot of time verses residual drawdown as shown on Figure 2. The method uses the following equation: T _ 2640 As Where T = Coefficient of Transmissivity (gpd/ft.) Q = Constant Pumping Rate (gpm) As = Slope of time versus drawdown graph expressed as the change in drawdown between any two times on the log scale whose ratio is 10 (one log cycle). 1 tj :,RESOURCE isitsliENGINEERIFiG t N O. Kevin Patrick Page 3 February 21, 2014 Using a As value of 0.18 feet from Figure 2 and an average pumping rate of 30.2 gpm the coefficient of transmissivity (T) = 44,450 gpd/ft. The Cooper -Jacob Straight -Line Method equation can be applied to data for both confined and unconfined aquifers. However, for unconfined aquifers drawdown must be corrected using the following formula: As'=L\s ts2 2D As = Slope of time versus drawdown graph expressed as the change in drawdown between any two times on the log scale whose ratio is 10 (one log cycle). As' = New drawdown D = Saturated zone of thickens (ft.) The As value was slightly changed to 0.176 feet. The Jacob equation was utilized in estimating the long term yield. The equation is as follows: s Where T = Coefficient of Transmissivity (ft.2/t) Q = Constant Pumping Rate (ft.3/t) S = Storage Coefficient (ft./ft.) s = Drawdown (ft.) t = Time (t) r, = Well Radius (ft.) In 2.25Tf 4mT rew s The storage coefficient was estimated using the time span during the pumping test where the well began to stabilize as shown plotted with an arithmetic scale in Figure 3. Using T = 4.1 ft2/min (44,450 gpd/ft.), Q = 4.1 ft3/min (30.2 gpm), s = 1.1 feet, t = 1440 minutes, r, = 0.25 feet (6 inch diameter well), the storage coefficient (S) was calculated to be 0.15 ft./ft. The storage coefficient was used to calculate the long term yield. The drawdown in the well was limited to 2 ft. and one year was used for time to ensure that the long term yield was calculated. Using S = 0.15 ft./ft., T = 4.1 ft2/min (44,700 gpd/ft ), s = 2.0 feet, t = 525,600 minutes (1 year), rW = 0.5 feet (6 inch diameter well), the long term pumping rate (Q) was calculated to be 5.17 ft3/min (38.7 gpm). The long term yield of the well appears to be in excess of the 30 gpm pumping rate achieved during the 24 hour test. RESOURCE estimates the long term yield of the well at approximately 40 to 50 gpm, depending upon how much the aquifer is drawn down. RESOURCE RESOURCE Kevin Patrick Page 4 February 21, 2014 recommends drilling a second well to provide a redundant supply and to allow for pumping at a flow rate that would not push the estimated maximum yield of the well. WATER QUALITY RESOURCE collected one water quality sample from the well water during the pumping test. The sample was shipped by overnight delivery under proper chain of custody to National Testing Laboratories (results attached). The results indicate that the well water meets the basic EPA primary and secondary drinking water standards. However, the well water did reveal a hardness of 230 mg/I, which is considered very hard. Hard water can cause scale to build up on water fixtures and lessen effectiveness of soaps. RESOURCE recommends installing individual water softening equipment as may be desired for each of the individual potable water uses. WATER RIGHTS The existing well was drilled under well permit No. 293077 issued by the Colorado Division of Water Resources (DWR) for a monitoring test well. A production well permit will need to be obtained to allow the well to be used for the AVR water system. The existing test well and the future well are/will be located within Service Area A of the Basalt Water Conservancy District (BWCD). An Area A Water Allotment Contract will be obtained from BWCD to replace the depletions from pumping of the wells. The BWCD Water Allotment Contract will provide the water rights necessary to obtain production well permits from the DWR. Please call if you have any questions or need additional information.

It is proposed to develop this Ranch for low density residential use. Planned buildings include: Homestead 1— 2 Employee Units equipment building Homestead 2 — Large (5,750 s.f.) residence 4 to 5 bedroom Homestead 3 — Large (5,750 s.f.) residence 4 to 5 bedroom Homestead 4 — Large (5,750 s.f.) residence 4 bedroom Homestead 5 — Large (5,750 s.f.) residence 4 to 5 bedroom Homestead 6 — Large (10,750 s.f.) residence 4 to 5 bedroom Homestead 7 — Large (10,750 s.f.) residence 4 to 5 bedroom Homestead 8 — Extra Large (;--- 12,750 s.f.) residence, 10 bedroom Homestead 9 - Extra Large 12,750 s.f.) residence, 5 to 10 bedroom possible Existing Ranch Center (caretaker unit, small office, Historic horse barn) Barn (with 1 bathroom) Club House — 3,500 s.f. no bedrooms, kitchen and 2 full bath Swimming Pool building locker rooms and kitchen Each of the above points of use is to be supplied with potable water. Potable water is also to be made available for limited building envelope irrigation. The system will serve less than 15 service connections (of any type). It is assumed that all residences will be second homes — with no year-round residents. An exception to this is the accomodations for full-time staff. The full-time staff, with dependents, will be less than 15 persons. Therefore, this proposed water utility is expected to be classified as non -community system, in accordance with the CDPHE New Water System Capacity Planning Manual. 6541 8291 ❑0❑0°❑ MERRICK`- ❑ob 8: COMPANY Aspen Valley Ranch McLaughlin Water Engineers A DMnlon of Menkk & Company s WATER QUALITY Following are summary quality characteristics for the different uses. Potable e In -Building Potable quality, good taste, no color, medium hardness; meet EPA/CDPHE requirements (to each site and Ranch Center). For In -Building Sprinkler System No gross contamination — require backflow prevention devices. Use potable water. For Local Landscaping (around each home site) N 10,000 s.f. (0.23ac) Can be potable or from indirect exempt wells or separate raw water source. If Potable, use limited to 0.23 ac ("10,000 s.f.) per lot/home site and immediate landscaping around the residence. The only significant additional irrigation water quality crietera, using potable water, would be the sodium obsorption ratio. WATER DEMANDS System peak day water demands are estimated as follows: In Building Residences (4 to 5 bedrooms) 4 each @ 800 gpd = 3,200 gpd Large Residences (4 to 5 bedrooms) 2 each @ 1,000 gpd = 2,000 gpd Extra Large Residences (average 8 bedrooms) 2 each @ 1,300 gpd = 2,600 gpd Caretaker Units 3 each @ 500 gpd = 1,500 gpd Club House = 600 gpd New Barn = 250 gpd Pool Building (drain and refill to be scheduled) = 750 gpd Ranch Center (office, Historic Barn, other) = 250 gpd Total Estimated Max Day In -Building Use 11,150 gpd 65418291 o❑og MERRICK Moo & COMPANY Aspen Valley Ranch 2 Mol.aughlln Water Engineers A 1iM*.0 of Mwikk Q Cc.np y Irrigation 12 Taps —10,000 s.f. each DESIGN CRITERIA = 2.8 Acres Max Day =32,000 gpd Total Max Day Use = 43,150 GPD Add 10 percent unaccounted for water Use 47,500 gpd Note: For Design purposes, provide 50 percent safety factor Use 70,000 gpd or 50 gpm Fire Protection For reliable protection, all fire fighting flows should be taken from the potable water system. This also dictates the need for 100 percent reliability. For this development, all buildings will be required to be sprinkled. Per ISO procedures, this reduces desired outside hydrant demand by 50%. Sprinkler design criteria should not affect distribution pipe sizing or other system design. It will affect customer service line sizing. Although (generally) sprinkler system installers prefer higher pressures, systems can be reasonably designed to function with pressures above 60 psi. Design fire flows are affected by structure size, use, and density. Information from the Aspen Fire Districtis that design hydrant flows should be 1,000 gpm for a 2-hour period. For safety factor (possible higher demand) it is recommended that a 1,200 gpm rate be used for fire protection flow design. This flow requires a residual pressure greater than 20 psi. 1 OVERVIEW The scope of this Master Plan is limited to the potable water system. All pastures, hay fields, and larger open area irrigation water is to be raw water from separate irrigation systems. Water is to be supplied from existing approved ponds and ditches. The lower irrigation system (for all areas below the Core area) may be be supplied from the lower pond, using a pumped pressursystem. Design of building may be integrated with the potable system as the Owner would like to minimize the number of structures on the Ranch — therefore, the two pumping stations may be combined into one building. The proposed Potable Water Master Plan is illustrated on the attached Drawing 1. The water supply will consist of 2 wells, developed in the Roaring Fork alluvium. Development of this source (drilling the wells and water rights issues) is the responsibility of Resource Engineering. Reuslts of their work are: Two similar wells will be developed, located approximately where shown on Drawing 1. Sustainable capacity of each well is 35 gpm or more. Basic water quality is suitable for potable use, requiring only disinfection treatment. Tested water quality results are shown in Table 1. The proposed water supply facilities will consist of: Two submersible well pumps with pitless adapters, each having a capacity of 35 gpm or greater. Well completion details to meet CDPHE criteria. Each well pump will deliver raw water to the central treatment plant/pumping station, using separate 2-inch interior diameter (ID) pipes. WATER TREATMENT/PUMPING STATION This building is to be located as shown on Drawing 1. It may be expanded to also provide for two irrigation pumps. Functional features will include: Two 2-inch flow meters Electrical equipment Chlorine solution feeder Possible backup generator In -line Ultra Violet unit Controls equipment (monitor tank level, wells status) Two 50 gpm high service pumps Sampling points.

Field reconnaissance determined that the highest reasonably available tank site would be on the previously platted Aspen Downs Lot 6 (which is not to be used for a private residence). The probable high water level (HWL) of this tank is 7,580 ft. The static pressures shown on Table 2 assume this tank site with a 10 ft. operating water level of 7,576 ft. Because of line sizing to accommodate fire flows, actual dynamic pressures will only be slightly lower. As shown by Table 2 the proposed tank site is appropriate, and the entire area can be served in one pressure zone. 65418291 Dr: MERRICK. on & COMPANY McLoughlin Water Engineers A (:: .vl ct tikerrok A ComPa7 Aspen Valley Rancll 6 PROJECT EXPERIENCE Eleven (11) fire hydrants have been approximately located as shown on Drawing 1. These have been sited to provide reasonable accessibility to each proposed structure. Fire hydrant locations are tentative; the Fire Department should review final design and advise as to precise location. Appropriate pipe selection for distribution systems in the mountain areas include ductile iron pipe (DIP) or high density polyethylene (HDPE). If HDPE is used, pipe locate records must be good (as -built drawings and locater wire). Actual pipe selection and piping details will be made during the Final Design Phase. Pipe sizes shown on Drawing 1 are ID. These sizes have been determined as adequate to provide design fire flows simultaneously with average day other demands. STORAGE TANK This system will have relatively high peak demands (as compared to the average daily demand) and can have extremely high fire fighting demands. With the realtively small, constant supply capacity, stored water is mandatory. It is always preferable to deliver peaking water by gravity (pumping not required) which is the situation here. Storage is designed to provide: Peaking Demands. The peak period use which exceeds the supply rate. This volume required is estimated to be 20,000 gallons. Reliability Storage. The system should be designed to supply normal demands with one well out of service. High service pumping capacity will be firm, i.e. adequate with one pump out of service. In the case of one well outage — reliability storage for a 7-day period would be approximately 100,000 gallons during a full occupancy summer peak period. Under average use conditions, or with curtailed irrigation, a volume of 10,000 gallons would usually be adequate. Storage should also be available for area power outage (unless standby power generation is provided). Approximately 80,000 gallons would be adequate for a two day outage during summer months. 80,000 gallons would provide full occupany water for over a week during the winter (no irrigation) season. Fire Fighting. Design fire fighting flow is 1,000 gpm (gallons per minute) for two hours — or 120,000 gallons. Because of the possibility of unusually large residences, the use of 1,200 gpm fire flow is recommended to provide a safety factor. This results in a design fire flow of 144,000 gallons. Summary Standard practice for municipal system design does not assume that a fire and a supply outage will occur at the same time. The recommended tank size is approximately 160,000 gallons. This tank will be approximately 40 ft. outside diameter with a side wall depth of 20 ft. The tank is to be reinforced concrete, complete buried, with the surface restored to the existing shape. An access hatch and vent will be visible. Depending on the selected control system, a nearby antenna may be necessary. The tank/system will be designed to provide hydraulic mixing - because of the relatively long average storage time involved. 65418291 00po MERRICK ` DOS & COMPANY McLaughlin Water Engineers A UN,W n of Monwk & Cornpary Aspen Valley Ranch i W I"' J >• z m OZ � oow W H D Z o, I Erma am�z OWD° notabs Jw1 V"'� met }); 0, z W (1)� � m 'd'd d O 0 1q4 1 I o 11 918 _ 1 • .-, '6 ! • - _t_- `.

Denver, Colorado 80246-1530 Phone (303) 692-2000 Located in Glendale, Colorado www.colorado.gov/cdphe May 23, 2014 Brooke Peterson, Owner Aspen Valley Ranch, AH LLC 514 E. Hyman Ave. Aspen, CO 81611 RE: Request for Information; Di inking Water Plans Submittal Aspen Valley Ranch, AH LLC, Aspen Valley Ranch Potable Water System Public Water System Identification (PWSID) No. CO0149124, Pitkin County Dear Mr. Peterson: Colorado Department of Public Health and Environment The Colorado Department of Public Health and Environment (Department), Water Quality Control Division has received and reviewed the plans and specifications, dated March 4, 2014 for the Aspen Valley Ranch, AH LLC, Aspen Valley Ranch Potable Water System. Because the Aspen Valley Ranch does not meet, or will not soon meet, the definition of a public water system as defined by Section 11.3(57) of the Colorado Primal y Di inking Water Regulations (Regulation 11), the Department does not have the authority by Regulation 11 to approve or deny the plans and specifications for const► uction of the water system. Howevei, the Department performed a preliminary review of the plans and specifications to determine general compliance with the requirements of the State of Colorado Design 0 iteria For Potable Water Systems (Design Criteria). At the time Aspen Valley Ranch meets, or would soon meet, the definition of a public water system, final plans and specification for the water system must be submitted to the Department for review and approval in accordance with Sections 11.4(1)(a) and (b). The Department will conduct a review of the submittal (i.e., plans, specifications, capacity assessment) in accordance with the requirements of Regulation 11 and the Design Criteria in effect at that time. The proposed public water system design does not meet the requirements of the Design Criteria and the review process for this project has been placed on hold because of the following issues: 1. According to Section 1.2.3(a) of the Design Criteria, the submittal requires water quality data to be collected or existing data summarized to either confirm the quality of a new source or to justify the selection of a treatment process. For each new groundwater source, a raw water analysis for all applicable MCL parameters for which the supplier of water is responsible for maintaining compliance must be submitted, with at least two full sample sets in different calendar quarters (four quarters of data are recommended). The submittal appears to have included one set of sample results from the proposed aquifer, and the sample results do not appear to include all the required raw water chemical analyses. Please provide two full sets of sample results from different calendar quarters to complete the raw water analysis (for each well if drawing water from different depths). Community systems are required to submit the following raw water chemical analyses: inorganics, nitrate, nitrite, sodium, corrosivity (temperature, pH, alkalinity, calcium, and TDS or conductivity), radioactivity, and organics. Brooke Peterson, Aspen Valley Ranch DYV Design Review - Request for additional information May 23, 2014 Page 2 of 4 2. Section 1.2.5(a) of the Design Criteria requires that the system demonstrate adequate water rights and permits through the Office of the State Engineer, Department of Natural Resources, Division of Water Resources (DWR). The engineering report indicates there will be two wells with a capacity of 40-50 gpm each. However, only one well permit was provided, and the permit authorized the use of the well to monitoring water levels and/or water quality sampling. To confirm the system has adequate water rights and permits, please provide additional information for the two wells, including the well log and the appropriate permit/application for each of the wells. 3. According to Section 1.2.5(d) of the Design Criteria, for new and updated pumping installations, supporting pump curves and limitations to provide adequate pumping capacity must be piovided. The engineering report indicates the pump station will meter and deliver treated water to the distribution system (including the finished water storage tank) using two 50 gpm centrifugal pumps. To check that the proposed pumps can supply adequate capacity at peak demands against the required distribution system pressure, please provide the system head curve, head computations for design conditions of the pumping system, and pump curves. 4. According to Section 1.2.5(b)(i) of the Design Criteria, identification of treatment goals including regulatory compliance requirements and process goals must be specified in the engineering report. The design proposes to utilize an ultraviolet (UV) reactor for additional disinfection treatment; however, no design parameters or calculations were provided for the UV treatment unit. Please specify if the UV unit will be used for regulatory compliance, and if so, please provide the additional information needed to review the UV unit for compliance with the design criteria listed in Section 4.4.9 of the Design Criteria. 5. In accordance with Section 2.10 of the Design Criteria, sample taps must be provided so that water samples can be obtained from each water source and from appropriate locations in each operating treatment unit and from the finished water. Based on the drawings, no raw water sample taps are provided for the wells. Please provide additional information, such as updated drawings, indicating that raw water sample taps will be provided. 6. According to Section 4.4.1.7 of the Design Criteria, the chlorine solution injector/diffuser must be compatible with the point of application to provide a rapid and thorough mix with all the water being treated. The diawings indicate that the chlorine feed discharges into the clearwell. This type of application does not seem to provide efficient mixing. Please piovide technical information on the application of the chlorine feed point to assure dispersion and thorough mixing of the chlorine within the clearwell. In addition, please specify the location of the chemical feed point for each well as the detail provided in the diawings indicates a single feed line. 7. In accordance with Section 4.4.2.c of the Design Criteria, groundwater systems must be designed for the capability to provide 4-log virus inactivation. Based on information in the submittal, the system has elected to perform triggered source water monitoring with the capability to provide 4-log inactivation of viruses in the event of a triggered source water event. The submittal package did not appear to provide disinfection calculations demonstrating the capability to achieve 4-log reduction/inactivation of viruses for the treatment facility. The calculation provided calculates the detention time provided in the serpentine contact tank (clearwell). Please provide chlorine contact time calculations that demonstrate the capability to achieve 4-log reduction/inactivation of viruses, accounting for the system's peak flow demand, minimum contact time volume with the appropriate baffling factor, pH, and minimum water temperature. 8. In accordance with Section 5.1.1.a of the Design Criteria, where a chemical feed is necessary for the protection of the supply including chlorination, coagulation and other processes required by regulatory requirements (e.g., pH adjustment for lead and copper compliance), a standby unit or a combination of units of sufficient size to meet capacity must be provided to r eplace the largest unit when out of service, and the Department may require that more than one be installed. The Department understands a sodium Brooke Peterson, Aspen Valley Ranch DIY Design Review -- Request for additional information A'lay 23, 2014 Page 3 of 4 hypochlorite feed pump will be provide for each well; however, please discuss how the system will meet the standby unit i equipment. 9. In accordance with Section 5.1.2 of the Design Criteria, feeders may be manually or automatically controlled, with automatic controls being designed so as to allow override by manual controls, and proportioned to flow. The submittal indicates the chlorine dosing rate is fixed injection adjusted to maintain a 1.5 mg/1 free chlorine residual; however, the design does not discuss how the chemical feed pumps will be controlled (e.g., activated via pressure switch) and how the chemical feed rate is proportioned to flow. Please discuss how the chemical feed pumps will be controlled, and how the chemical feed rates will be determined. 10. In accordance with Section 5.1.10 of the Design Criteria, storage tanks for liquid chemicals must be specified for use with individual chemicals. The Department understands sodium hypochlorite will be used for disinfection; however no equipment specifications were provided fot the chemical storage tank. Please provide information pertaining to the sodium hypochlorite feed tank including volume, material, cover, and secondary containment. 11. Section 7.0.6.a of the Design Criteria requires adequate controls be provided for tank turn over to maintain water quality. Control design must facilitate turnover of water in the finished water storage tank to minimize stagnation and/or stored water age. The design indicates the 160,000 gallon buried concrete storage tank will be fitted with a hydraulic mixer, and operated to reduce the average residence time of the finished water. To check that the stored water age will be managed appropriately, please provide a description demonstrating how the system will plan to manage the water quality in the finished water storage tank. Water storage management for water quality must take into account influent water quality, retention of fire flow, demand management, as well as factors specific to the design and operation of the tank such as fluctuation of the water levels in the storage tank for complete water turnover. 12. In accordance with Section 7.0.7.a of the Design Criteria, all storage structures must be provided with an overflow. The setpentine contact tank (clearwell) does not appear to be constructed with a tank overflow. Please update the design/drawings to include an overflow. 13. In accordance with Section 7.0.7.h of the Design Criteria, the top of the overflow must be a minimum of one foot below the lowest point of the roof structure. Based on the information provided, the separation distance from the underside of the roof of the 160,000 gallon buried concrete storage tank and the top of the inlet of the overflow is 0.83 feet. Please update the design/drawings to provide the minimum of one foot of sepai ation between the top of the overflow and the lowest point of the roof structure. 14. In accordance with Section 7.0.8 of the Design Criteria, finished water stoi age structures must be designed with reasonably convenient access to the interior for cleaning and maintenance, and at least two access openings must be provided above the waterline at each water compartment. The 160,000 gallon buried concrete storage tank appears to have one access point to the tank. Please update the design to include two access points to the interior of the tank for cleaning and maintenance as required by this criteria. As stated in this Section of the Design Criteria, each access opening must be elevated at least 24 inches above the top of the tank or ground surface and be fitted with a solid water and insect tight cover which overlaps a framed opening and extends down around the frame. The frame must be at least four inches high. Each cover must be hinged on one side, and must have a locking device.
