ELK SPRINGS, LC C By l^'ti Gary McElwee, Attorney -in -Fact for Thomas E. Neal 8 2-9 2016 Date GARFIELD COUNTY BUILDING AND PLANNING DEPARTMENT FEE SCHEDULE Garfield County, pursuant to Board of County Commissioners ("Board") Resolution No. 98-09, has established a fee structure ("Base Fee") for the processing of each type of subdivision and land use applications. The Base Fee is an estimate of the average number of hours of staff time devoted to an application, multiplied by an hourly rate for the personnel involved. The Board recognized that the subdivision and land use application processing time will vary and that an applicant should pay for the total cost of the review which may require additional billing. Hourly rates based on the hourly salary, and fringe benefits costs of the respective positions combined with an hourly overhead cost for the office will be used to establish the actual cost of County staff time devoted to the review of a particular project. Actual staff time spent will be charged against the Base Fee. After the Base Fee has been expended, the applicant will be billed based on actual staff hours accrued. Any billing shall be paid in full prior to final consideration of any land use permit, zoning amendment or subdivision plan. If an applicant has previously failed to pay application fees as required, no new or additional applications will be accepted for processing until the outstanding fees are paid. Checks, including the appropriate Base Fee set forth below, must be submitted with each land use application, and made payable to the Garfield County Treasurer. Applications will not be accepted without the required application fee. Base Fees are non-refundable in full, unless a written request for withdraw from the applicant is submitted prior the initial review of the application materials. Applications must include a Payment Agreement Form ("Agreement") set forth below. The Agreement establishes the applicant as being responsible for payment of all costs associated with processing the application. The Agreement must be signed by the party responsible for payment and submitted with the application in order for it to be accepted. The following Base Fees shall be received by the County at the time of submittal of any procedural application to which such fees relate. Such Base Fees shall be in addition to and exclusive of any cost for publication or cost of consulting service determined necessary by the Board for the consideration of any application or additional County staff time or expense not covered by the Base Fee, which have not otherwise been paid by the applicant to the County prior to final action upon the application tendered to the County.

Specific submittal requirements are identified in Article V Divisions of Land 5-501 Application Materials for Division of Land Section E. Final Plat 4.a. — h. Elk Springs has completed construction of most of the infrastructure necessary to serve the areas encompassed in these Final Plats. Filing 6A is directly accessed from CR 114. This parcel will undergo the Preliminary/Final Plan process for site specific features and any re- subdivision. As all of the other utilities are in place adjacent to the parcel, a new sanitary sewer is the only proposed construction at this time. All roads, utilities and drainage infrastructure are in place to serve Filing 8, Phase 2 and Filing 9. The Kingbird Drive cul-de-sac, serving lots 79 and 80, is the only exception to this in Filing 9. Filing 10 is a Rural Residential lot with access and utilities from CR 114. The parcel will utilize an individual well and ISDS and no public improvements are proposed. In addition to the respective Final Plats, this application includes the fallowing engineering plan sets: • Elk Springs Filings 8 — 9 Final Plat Submittal — these are the updated Preliminary Plan drawings that Filing 8 and 9 infrastructure was constructed from. (Appendix A) • Record Drawings Filings 8 and 9 - these are surveyed record drawings of the as - constructed utilities with the Filings. (Appendix B) • Kingbird Drive — these sheets are the design drawings for the infrastructure necessary to serve the two new lots in Filing 9. (Appendix C) • Filing 6A Neighborhood Commercial — these sheets show topography and sanitary sewer design necessary to serve this parcel. (Appendix D) The subject filings underwent the Garfield County Preliminary Plan review process in 1998 and Amendment in 1999. This engineering design presented in this Final Plat is consistent with the Preliminary Plan Filings 6 —10 and 1999 Amendment. Applicable reports from those applications are included in the Appendices. 2,0 5treets, Trails Walkways and Bikeways With the exception of Kingbird Drive cul-de-sac, all roads associated with this application have been constructed in accordance with the Preliminary Plan approval and as shown in the plans provided. In general, the Filing 8 and 9 roads are chip sealed wit two 11' lanes and gravel shoulders. Road grades are < 6% and were designed to fit into the natural topography with minimal disturbance. Preliminary Plan Exhibit D described roadway classification and design and is included in its entirety here as Appendix E. Separate trails, walkways and bikeways are not proposed as "hard" construction. However, the Final Plats do provide easements that allow for non -motorized travel and access to open 1 Elk Springs/ Los Anugos Rancn November 2010 space areas. The low density and rural nature of the development allows the roads to be safely used to access these easements. 3.0 Drainage Drainage features on Elks Springs consist primarily of roadside ditches and cross culverts. The low density of the development allowed natural drainage patterns to be maintained. Runoff rates and volumes are comparatively low due to good vegetative cover and predominant Hydrologic Soil Group B soils having high infiltration capacity. Again, all public drainage infra -structure necessary for these final plats is already constructed. Refer to the Filings 8 — 9 drawings for locations, sizes, and details associated with culverts, swales, etc. The Preliminary Plan application included a detailed and comprehensive drainage report. Again, that report is included in Appendix E. 4.0 Geologic Hazards Elk Springs' geology was studied extensively. Applicable reports by Lincoln DeVore, Hepworth-Pawlak Geotechnical Inc. and CTLfThompson Inc. from the Preliminary Plan Exhibit E are included in Appendix F. Of specific concern for this application are the faults and landslide areas in Filing 8, Phase 2. The conclusions reached are that the landslide area is ancient and now stable and the large lot size will allow residential development as contemplated in areas away from the faults. 5.0 Sewage Collection Elk Springs is served by a central wastewater collection and treatment system operated by the Spring Valley Sanitation District (SVSD). A network of existing gravity and low pressure sewer lines collect sewage from individual lots throughout the development and route it to the SVSD treatment facility. Such is the case for Filing 9. A new 8" gravity sanitary sewer will be constructed for Filing 6A. Individual Septic Disposal Systems will serve the Rural Residential lots of Filings 8, Phase 2 and Filing 10, These lots are very large, have suitable soils and ISDS's will provide a safe and practical means of sewage disposal. Garfield County Resolution No. 99-102 specifically approved the use of ISDS on these lots. Appendix E contains extensive discussion on the Sanitary Sewage Disposal Plan. 6.0 Water 'Supply and Distribution With the exception of Filing 16, all lots will be served by the existing central water system owned by the Elk Springs Homeowners Association, Inc. and operated by the Red Canyon 2 Elk Springs/Los Amigos Ranch November 2010 Water Company. That central water system consists of a well field that pumps to a chlorination facility and contact chamber before entering the transmission and distribution network. That network consists of 10", 8" and 6" waterlines linking the 320,000 gallon East Tank and the 150,000 gallon west tank. Fire protection is provided by the Carbondale and Rural Fire Protection District. The District advised on storage capacity and hydrant layout throughout the development. Appendix E provides full details on the Water Supply Plan. 7.0 Soils Appendix G contains soil information for the project taken from the USDA National Resource Conservation District. This was submitted as Exhibit I with the 1998 Preliminary application, Soils are generally well-suited for development in the areas proposed. Appendix F provides a geotechnical analysis and provides specific recommendations, 8.0 Groundwater Groundwater drainage is not a problematic issue in Elk Springs. No free water was encountered in the 21 test pits ranging from 2' to 8' deep logged in the H -P Geotech Report in Appendix F. Foundation drains are recommended as a precaution against locally perched groundwater. Groundwater was not a significant issue in the construction of public improvements or residences. 9.0 Erosion and Sediment Control This report, in conjunction with the project plans contained in Appendices A — D, addresses the requirements of 4-502 (C)(4). There are no major water bodies with in the development. Existing drainage features consist of roadside ditches, swales, culverts and detention ponds. Refer to Appendices A — D plans for topography, grading and locations and sizes drainage elements. Appendix E contains drainage calculations. Snow storage areas are immediately adjacent to the road within the rights-of-way. The Kingbird Drive cul-de-sac and Filing 6A sewer construction will require clearing and grubbing and stockpiling of soil immediately adjacent to the construction within the rights-of- way. The steepest adjacent grades on Kingbird are about 7 %. The sewer construction is generally on existing grades of about 8 % while a short section will be installed on a 14% grade. There are no steep grades greater than 20 % that will be disturbed. No temporary roads are anticipated. Construction of the Kingbird Drive cul-de-sac and Filing 6A sewer line will occur in the spring, summer or fall of 2011. The construction period for each project is not expected to exceed 30 days start to finish. 3 E k Springs/Los Amigos Ranch November 2010 The Kingbird Drive cul-de-sac receives virtually no runoff from adjacent area. No specific erosion measures are proposed other than appropriate, good housekeeping measures, The minimal runoff that could leave the construction area will flow as sheet flow and be filtered across natural vegetated areas. For the Filing 6A sewer construction, erosion control and best management practices will be in place at the start of construction. As some tributary drainage area does exist, erosion logs as shown on the plans will be installed to control any sediment laden runoff. Good housekeeping measures will be expected and additional best management practices as warranted by contractor operations will be utilized. Permanent stabilization will consist of topsoiling, seeding and mulching. The erosion logs and any other controls will be left in place until after vegetation is established. The total cost of erosion control and permanent stabilization is expected to be less than $3000. Refer to cost estimates presented in the next section of this report. Total estimated disturbed area is about 16,850 sf for the Kingbird Drive construction and about 17,000 sf for the Filing 6A sewer project. Adjacent areas at Kingbird are sage with grass. Pinyon/Juniper with grass understory is adjacent to the Filing 6A sewerline while much of the alignment is in the old CR 114 platform. Hydrologic Soil Group "B" soils predominate and have high infiltration capacity resulting in lesser amounts of runoff. These projects will not require a CDPHE Stormwater Management Plan for Construction Activities as the resulting disturbance is well less than 1 acre in each case. As such, separate signature blocks for erosion and sediment control are not provided, 10.0 Public Improvement Cost Estimates Public Improvement cost estimates for the Kingbird Drive cul-de-sac in Filing 9, and the extension of sewer to the Neighborhood Commercial lot in Filing 6A, together with documentation of the actual cost of completed construction in Filings 8 and 9 are included in Appendix H. 4 Elk Springs/Los Amigos Ranch November 2010 Appendix A Drawings Elk Springs Filings 8 — 9 Final Plat Submittal C Final Plat Engineering Report Appendix A C 1 OC Col (•• 4-1 Con4t CD (24 coo FINAL PLAT SUBMITTAL A //ABEAM/ FPEPARED ar- ( Yt7.f:�nFD.+S P4R rQF } a n mR4KR;R ) .1 7: 08: tr •11 • - - • ee §-Z‘ 9 -\\ 2 ki4n. cr.!' nft Cr9/ PY 4,11P(41 41. ; fa!

Specifically, certain portions of Section 4:00 Preliminary Plan of the Garfield County Subdivision Regulations, as further outlined below, are addressed. This Preliminary Plan will consist of 168 single-family homes located immediately north and west of existing prior filings of Los Amigos Ranch PUD. included will be four Rural Residential lots in excess of 35 acres located generally in the southwest part of the project. 4:80 DRAINACQE PLAN Attached hereto please find Los Amigos Ranch Preliminary Plat Drainage Report. The methodology used is outlined in the attachment. The locations of drainage facilities are shown on the Drainage Master Plan Sheet LAD and the various roadway plan & profile sheets of the Preliminary Plan drawings. There are no existing water courses or lakes on this property. Tributary areas are localized in nature. Because of the large size of the lots, any increase in historic flow rates from these filings will be negligible. Downstream drainage facilities have already been sized as part of previous submittals to account for the drainage from these filings. No adverse impacts from the construction of these filings are anticipated from a drainage standpoint. 4:91 WATER SUPPLY PLAN All of the lots proposed as part of this Preliminary Plan submission will be serviced by the extension and improvements of the existing central water system. In the case of the Rural Residential lots, alternative service with either individual wells or central water system extension is proposed. January 19, 1998 Mr. Greg Boecker Page 2 Existing Water System The existing system consists of two drilled wells, identified as Weil No, 5 and Well No. 6, a 320,000 gallon water tank, a control/chlorination building, numerous fire hydrants and a distribution system consisting of 10", 8" and 6" piping which serves all previous filings within Los Amigos Ranch PUD. Two pressure reducing valve (PRV) stations divide the system into two pressure zones. The locations of the existing water system components are on the Preliminary Plan Master Water Plan Sheet LAU-2. Well No. 5 is a 5" steel cased well approximately 170 feet deep. The well has a static water level of 80 feet and has been test pumped in the past to a total of 110 gpm with only a four foot draw down. Estimated potential well capacity is estimated in excess of 300 gpm. Well No. 6 is a 10" steel cased well with a total depth of approximately 260 feet. This well has been test pumped in the past at 400 gpm. Current combined well yield of these two wells is approximately 510 gpm with a total potential yield in excess of 600 gpm. The control/chlorination building contains the operating controls for the system. The required 30 -minute chlorine contact time is provided by 460 feet of 24" water main within the system. The total volume contained within the piping is 10,800 gallons which provides more than 30 minutes of detention at the peak day pumping rate at build -out of the project of 233 gpm. The water system is classified as a public water supply by the Colorado Department of Health. Both the quality and bacteriological content of the water has consistently met all parameters of the State of Colorado Primary Drinking Water System, Water Requirements Table 1 enclosed herein indicates the current water requirements for Los Amigos Ranch PUD and the water requirements for Filings 6 to 10. The water system will provide both in-house domestic use and outside lawn irrigation uses. Average and peak day demands are calculated for both irrigation and non -irrigation seasons. As noted in Table 1, the water system has been sized to include the service of the Residential Rural tots, should they require service. Proposed Water System Components The proposed water system components to accommodate Filings 6-10 are shown on the Preliminary Plan Master Water Plan Sheet LAU-2. New 10", 8" and 6" transmission and distribution lines will be installed along with fire hydrants and 1" or 1 f2" water services for each lot. A new 150,000 gallon steel water tank will be required in the western portion of the SCHMUESER GORDON MEYER, INC. 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 January 19, 1998 Mr. Greg Boecker Page 3 project once development proceeds into Filing 9. The CYBERNET computer model was used to calculate pressures and determine required line sizes throughout the system. Fire flow demands, rather than peak hour demands, govern the design of the system. Lines were sized with the goal of providing a fire flow of at least 500 gpm at 20 psi. This was achieved in all areas. The fire hydrants were placed where they would benefit the most lots. The hydrant layout shown on LAU-2 has been done consistent with discussions with the Carbondale and Rural Fire Protection District. Due to the large line sizes used, pressure differences that would occur under static conditions and peak day demands are negligible. Assuming a mid -tank level, a maximum pressure of about 135 psi would be observed in the lowest portion of Filing 8. Some low pressure levels will occur on the Tots in the northeast portion of the project in the vicinity of the water tank. The Water Master Plan Sheet LAU-2 indicates lots which fall above the elevation 7090/40 psi line. The significance is that, depending on where the actual homesite is situated, individual lot owners may wish to install a pump and pressure tank to obtain higher, in-house pressures. One and one-half inch diameter water services are also recommended for these lots to minimize the headloss that would occur from the water main to the house. The attached report entitled, "Los Amigos Ranch Preliminary Plat, Filings 6-10, Water System Calculations" contains a computer model schematic and results of the fire flow analysis. Again, the maximum day pressures listed were virtually the same as the maximums observed under static conditions. Separate fire flow runs are provided for an analysis of the complete system with both tanks on line and "an east tank only" scenario which excludes Filing 9. The existing 320,000 gallon east tank was over -sized to accommodate potential future filings. Considering those areas east of Filing 9 and the water demands referenced in Table 1, the minimum required tank volume can be calculated as follows: EAST TANK Equalization 25% average total demand' 33,673 gallons Fire Flow 15002 gpm x 2 hours 180,000 gallons Emergency 1 average day (domestic) 58,240 gallons Minimum required volume 271,913 gallons 1 Domestic and irrigation 2 Auburn Ridge Apartments only; 500 gpm single family lots. SCHMUESER GORDON MEYER, INC. 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 January 19, 1998 Mr. Greg Boecker Page 4 Considering the incremental storage required to serve Filing 9, the minimum size of the western tank can be calculated as follows; WEST TANK Equalization 25% Average total demand' 8,255 gallons Fire Flow 5007 gprn x 2 hours 60,000 gallons Emergency 1 average day (domestic) 13,770 gallons Minimum required volume 82,025 gallons 1 Domestic and irrigation 2 Single family lots Rural Residential Lots For purposes of sizing the central water system, service to the four (4) Rural Residential lots was assumed to be part of the water system. Because of the size of these lots and their location relative to the remainder of the project and the water system, this plan proposes as an alternative the ability to drill an individual welt on each of these lots. With respect to the history of well development in this area, we have reviewed records available from the District Engineer's Office and have talked to local well drillers familiar with groundwater conditions. Wells have been variable with respect to well depth and well yield. Generally, the wells have been completed in bedrock formations or in the alluvial layers immediately above bedrock interfaces. Well yields are generally less than 10 gprn which would indicate intermediate storage between the well and the residence may be required depending upon total well yield. We anticipate the water would be classified as "hard", but that all Colorado Primary Drinking Water Standards will be met. Depending on the degree of hardness, water softening may or may no be elected by the homeowner. With respect to fire protection for these lots, it is proposed to provide a 2000 gallon cistern with draft pipe for use by firefighting apparatus. This cistern would be located near the residence and would be sited at the time that an architectural site plan is available for the residential building construction.

Those portions of the PUD serviced by SVSD are properties which generally lie within the Spring Valley aquifer drainage and can be serviced by gravity collection sewerlines. The approximate boundaries of the Spring Valley aquifer have been established during prior approvals. Lots With Central Sewage System This application does not request Preliminary Plan approved for any residential or commercial lots which are within the SVSD or the western boundary of the Spring Valley aquifer. Residential Lots With ISDS Referencing the geotechnic report prepared by Hepworth-Pawlak included in this application, there have been nine percolation tests conducted throughout the filing. The percolation test results range from 11 minutes per inch to 40 minutes per inch. These percolation rates are indicative of subsurface conditions which are acceptable for ISDS to be constructed. The percolation tests were run at locations and in site soils conditions that are representative of the overall conditions throughout the project. Additionally, there are ten (10) units within the existing Los Amigos Ranch PUD which have installed and are using ISDS for sewage service. To the best of our knowledge, adequate percolation and subsurface conditions were found at all these sites and standard ISDS utilization. Environmental and Health Impacts Analysis Garfield County Sewage Disposal Regulations which, in turn, are based on the "Guidelines on Individual Sewage Disposal Systems", Colorado Department of Health, set forth the conditions and regulations under which the County and the State of Colorado have determined are appropriate to the construction of ISDS. These regulations are very comprehensive with respect to site characteristics which determine the type and size of the system which can be constructed. Those regulations recognize the ability of a soil matrix to provide the necessary treatment to septic tank effluent such that, once the effluent passes through the soil matrix, the treated effluent does not pose a public health hazard or risk. The regulations further address the potential for cumulative impact of ISDS systems by specifying the minimum lot sizes that should be utilized for 'ISDS systems. ISDS technology recognizes that there are certain instances where there are inherent restraints to the use of ISDS's. These restraints include high groundwater table, underlying bedrock formations, inadequate percolation rate, horizontal separation from wells and water courses, SCHMUESER GORDON MEYER, INC. 1 1 1 1 January 19, 1998 Mr. Greg Boecker Page 6 and excessive percolation rate. Whenever any of these restraints exist, the regulations require that they be identified and that the system installed when restraints occur, be designed under the direction of a registered professional engineer in the State of Colorado. A "standard" ISDS system, typically consists of a septic tank and leach field. In order to use a standard ISDS, the underlying soil matrix should demonstrate percolation rates within acceptable defined limits and there should be identified no restraints to the installation of the system. As stated above, all systems currently installed within the Los Amigos Ranch PUD are standard systems, with acceptable percolation rates existing and no restraints to construction identified. Based upon data now available, it is anticipated that for Filings 6-10, that the majority of 1505 systems that will be installed will be standard systems. In those cases, percolation tests and profile holes will be excavated at the location and depth of the proposed leach field at each individual building site in accordance with Garfield County regulations. The results of those tests will be analyzed and the system design based on percolation rate and size of residence. It is anticipated, that any restraints that may be encountered in the area encompassed by Filings 6-10, they will be associated with shallow bedrock formations. In the event that such conditions are identified at an individual residence location, it will be necessary to construct an engineered system. The regulations require there be a minimum of four feet of soil matrix between the bottom of the leach field and the bedrock restraint. In the event there is. insufficient soil matrix available, then the existing soil matrix will need to be augmented with imported materials such that the minimum four -foot depth exists. This type of construction is typically referred to as a "mound system" and is a construction technique that is standard to the industry and has been used in Garfield County where shallow restraints such as bedrock or groundwater have been encountered. The mound system is designed with the soil materials to be used for its construction as well as the size of the residence taken into account. The resulting installation, consistent with both Garfield County and State regulations, results in a system which provides for treated effluent being discharged through the bottom of the leach field. Although not anticipated, there is the possibility that under the applicable regulations the restraints on a particular building site will preclude the use of a standard or mound system using a percolation process. In these instances, it may be necessary to construct an evapotranspiration (FT) type of system. An ET system does not use percolation as a disposal means but, rather, uses evaporation and transpiration for disposal. These systems are typically lined with an iimpervious liner and size based on the size of the residence and background climatic conditions. Again, these systems are standard to the industry and their design and operation is well documented. It is our opinion that there is strong likelihood that a standard septic tank/leach field system can be utilized as the ISDS for these lots. The most likely restraints to the development of a standard system would be shallow bedrock conditions. In the event any restraint is identified, it is our further opinion that an engineered system, either a mound -type system or an SCHMUESER GORDON MEYER, INC 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 January 19, 1998 Mr. Greg Boecker Page 7 evapotranspiration (ET) system could be constructed on the lot and satisfy all applicable regulations. Consistent with standard practices of the Environmental Health Department of Garfield County, percolation tests and a profile hole will be required on each lot at the exact location of the !SDS at the time that a building permit is requested. At that time, a final design for the ISDS will be required. Filings 6-10 comprise a total land area of approximately 75 million square feet or 1725 acres. The filings stretch for approximately 13,000 lineal feet along a line roughly parallel with the Roaring Fork drainage basin located, on average, approximately 900 to 1000 feet in elevation below the site. The overall density of ISDS on the site is approximately one system per 10 acres. This density is over 10 times less than the allowable density of one -acre lots where an ISDS and central water system provide service, as in the case of the Los Amigos Ranch PUD, and over five times less than the allowable density of two acre Tots where individual lots are served with ISDS and an individual drilled well. Both the Garfield County regulations and the State Health Department regulations have been based upon accepted scientific standards of the industry which protect against any possibility of any environmental impacts affecting public safety. In conclusion, it is our opinion that ISDS can be constructed for all the proposed lots within Filings 6-10 of the Los Amigos Ranch PUD that meet applicable Garfield County and Colorado Department of Health standards of construction and design. If these systems are constructed and designed in accordance with these regulations, then there will be no adverse environmental or health impacts from the use of ISDS as proposed. Attached to this letter report is a "Management Plan Far Individual Sewage Disposal Systems", As stated in the Plan, the purpose is to provide for the regular operation and maintenance of ISDS. This Plan has previously been incorporated into the covenants of Los Amigos Ranch PUD. The Plan will be included in the covenants adopted as part of the Preliminary Plan. Also attached to this letter report is a letter from Hepworth-Pawlak dated January 19, 1998, which further summarizes the field investigations performed on this site. As stated in the letter, Hepworth-Pawlak reiterates their conclusion from their original study which indicates that this site is suitable for individual septic systems while recognizing that mounding or other engineered systems may be required where a shallow bedrock restraint might be encountered. ROADWAY INFRASTRUCTURE Roadways within this project have been sized in accordance with current requirements of the Garfield County Subdivision Regulations. Estimated service requirements are based on 10 vehicle trips per day {VPD) per individual lot. Typical road sections for the different roadway classifications are contained within the Preliminary Plan drawings. SCHMUESER GORDON MEYER.

We have received a copy of the first 4 pages of preliminary plat review letter by Wright Water Engineers to Garfield County dated January 9, 1998. We performed a preliminary geotechnical study for the project under Job No. 196 617, dated February 14, 1997. Individual Septic Systems: Percolation tests were conducted in January, 1997 to evaluate the feasibility of individual septic systems at the site. The percolation rates varied from 11 to 40 minutes per inch. The average of eleven percolation tests was about 24 minutes per inch. The tests were performed between 3 and 5V2 feet below the ground surface. All the tests were performed in the overburden soils above the basalt flow rock. Partial refusal to digging by the Case 780C rubber -tired backhoe was encountered shallower than 8 feet deep in 15 of21 pits. The average refusal depth was 4V2 feet. Whether the refusal was on intact basalt flow or on basalt boulders within the overlying basalt colluvium soils could not be determined in the relatively small backhoe pits. Based on our experience in the area and the site geology, we expect that the basalt flow is close to the refusal depths encountered in the pits. The development should be suitable for individual septic systems. Mounding or other engineered systems may be required in shallow basalt rock areas. The system designs should be based on site specific soils information. If you have any questions, please contact our office. Sincerely, JIEPWORTH-PAWLAK GEA ►'' 1 AL, INC.

Personnel 109 8th Street, Suite 303 Glenwood Springs CO 81601 RE: Los Amigos Ranch Preliminary Plat Pilings 6 through 10, Drainage Dear Mark: This letter transmits additional drainage information as a follow-up to our Tuesday, February 24, 1998 meeting. Recapping, Wright Water Engineers recommended in their January 9, 1998 letter that an analysis of existing conditions be conducted to facilitate an analytical comparison for downstream impacts of the development. This was based on Garfield County Subdivision Regulations, Section 9:43 which states "Where new developments create runoff in excess of historic site levels, the use of detention ditches and ponds may be required to retain up to the 100 -year storm". These calculations were included in our re -submission and showed that the low density of the project resulted in minimal increases in flood flows. Nonetheless, there was still concern expressed at our meeting over the perception of downstream property owners. While Wright Water Engineers generally agreed that the effects of the increased runoff on downstream drainage structures would be minimal, they still thought that it would be in the County's best interest to have an analysis of the structure showing that the effects of the increases were, in fact, minimal. Another option would be to provide detention and release flood flows at less than historic levels. The revised copy of Sheet LAD, the Drainage Master Plan, shows how detention storage could be incorporated into the Los Amigos Preliminary Plan. The four major points of concentration for drainage Leaving the project are identified as Discharge Points 1 through 4. Tributary areas for each of these points have been identified and are shown by thick, dashed lines. Potential detention areas are shown by hatching. A thick dotted line indicates the portion of the basin tributary to the detention ponds. Detailed hydrologic and hydraulic calculations (using the methodology appropriate for larger basins), as welt as a site survey, will need to be performed for each detention pond location. A trial and error procedure will be utilized to determine the optimal outlet configuration and storage volume that results in a 100 -year flow rate that is less than historic at the four discharge points. This detailed level of analysis and design would be performed prior to the Final Plat submission. 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 February 27, 1998 Mr. Mark Bean Page 2 in summary, the low density of the development results in minimal flood peak increases that can be easily mitigated by standard engineering practices if the County deems this necessary. Additionally, an analysis of downstream structures could be performed which would show that the effects of these minimal flood peak increases would be unnoticeable. As a last resort,improvements could be made to downstream drainage structures. Please do not hesitate to contact me if you require additional clarification on any of the items discussed.

Due to the fact that the project is located near the ridge of a hill, off-site water sheds were a small influence to the overall drainage of the project. The slope of the land from south to north also allows the drainage to be carried by roadside ditches with minor cross culverts at intersections and low points. TR -55 and Rational Method are two means of determining peak flows within a small to medium size basin. The Rational Method was chosen for this analysis due to the fact that, in this area of Colorado, it generally predicts higher flood peaks than those produced by a TR - 55 analysis. The procedure for using the Rational Method is one that utilizes a runoff coefficient, the rainfall intensity corresponding to the time of concentration of the basin, and the overall basin area in acres to calculate the flood peak in cubic feet per second. The runoff coefficients are based on land use, soil type and slope. The Soil Conservation Service Soil Study for Garfield County (Figure 1) shows that soils found within these drainage basins are classified as soil group 6. The runoff coefficient for this project was calculated using a weighted formula for impervious and pervious areas as shown: Weighted C = [40.95 * A;mpervrOlh51 + (0.26 * ApOMOUIOtRi ll/A The overall drainage plan is shown on Drawing LAD of the Preliminary Plan drawings. Many different basins (Figure 2) were identified and used in hydrologic calculations. The areas for basins extending outside the property area were determined by planimetering boundaries on 1" = 2000' USGS quadrangle maps. A 1" = 500' scale AutoCADD map was used to calculate basin areas within the property. In the case of minor basins, areas under two acres, a minimum culvert size of 16" was used, Also, ditch flows were found using a percentage of total basin flows since only parts of the basins are intercepted by roadside ditches. The remainder of this report consists of tables showing the results from hydrologic calculations performed and drainage elements to be used. Followed by spreadsheet information used to calculate times of concentration for each basin.

Suite 200 Glenwood Springs, CO 81601 June 22, 1999 Mr. Greg Boecker, Owner's Representative Los Amigos Ranch Partnership 2929 County Road 114 Glenwood Springs CO 81601 RE: Application to Amend Preliminary Plan Submission Los Amigos Ranch PUD - Filings 6 thru 10 Dear Greg: This letter is in support of an Application to Amend the Preliminary Plan submission for Filings 6 to 10 of Los Amigos Ranch PUD. Specifically, certain portions of Section 4:00 Preliminary Plan of the Garfield County Subdivision Regulations, as further outlined below, are addressed. This Amended Preliminary Plan will consist of 178 single-family homes and a neighborhood commercial parcel located immediately north and west of existing prior filings of Los Amigos Ranch PUD. Included will be four Rural Residential lots in excess of 35 acres located generally in the southwest part of the project. 4:80 DRAINAGE PLAN Attached hereto please find Los Amigos PUD Ranch Preliminary Plat Drainage Report. The methodology used is outlined in the attachment. The locations of drainage facilities are shown on the Drainage Master Plan Sheet LAD and the various roadway plan & profile sheets of the Preliminary Plan drawings. There are no existing water courses or lakes on this property. Tributary areas are localized in nature. Drainage Master Plan Sheet LAD shows the locations of minor on-site drainage basins denoted by Basin 'XX". The locations of major drainage elements required to convey stormwater are denoted by a leader with the label "DE #XX". The Drainage Master Plan also shows information relating to the storrnwater detention concept developed in conjunction with Wright Water Engineers' review of the approved Filings 6 thru 10 Preliminary Plat. The pian shows the locations of the four major discharge points for Los Amigos Ranch PUD denoted by "DP #X". Subareas indicated by heavy dashed lines are labeled "DPX.X" Cross -hatched areas within each drainage basin indicate the locations of proposed detention ponds. These ponds will attenuate the post -development flood peaks for both the 25 -year and 100 -year floods to levels below those that would occur under June 22, 1999 Mr. Greg Boecker Page 2 historic undeveloped conditions. An April 1998 report entitled "Los Amigos Ranch PUD Preliminary Plan, Filings 6 thru 10, Stormwater Detention Analysis" presented the lengthy hydrologic and detention routing calculations. Copies or this report are not included in this submission, but will be gladly furnished upon request. 4:91 WATER SUPPLY PLAN All of the lots proposed as part of this Amended Preliminary Plan submission will be serviced by the extension and improvements of the existing central water system. In the case of the Rural Residential lots, alternative service with either individual wells or central water system extension is proposed. EXISTING WATER SYSTEM The existing system consists of two drilled wells, identified as Well No. 5 and Well No. 6, a 320000 gallon water tank, a control/chlorination building, numerous fire hydrants and a distribution system consisting of 10", 8" and 6" piping which serves all previous filings within Los Amigos Ranch PUO. Two pressure reducing valve (PRV) stations divide the system into two pressure zones. The locations of the existing water system components are on the Preliminary Plan Master Water Plan Sheet LAU-2. Well No. 5 is a 5" steel cased well approximately 240 feet deep. The well has a static water level of 80 feet and has been test pumped in the past to a total of 110 gpm with only a four foot draw down. Estimated potential well capacity is estimated in excess of 300 gpm. Well No. 6 is a 10" steel cased well with a total depth of approximately 260 feet. This well has been test pumped in the past at 400 gprn. Current combined well yield of these two wells is approximately 510 gpm with a total potential yield in excess of 600 gpm. The control/chlorination building contains the operating controls for the system. The required 30 -minute chlorine contact time is provided by 460 feet of 24" water main within the system. The total volume contained within the piping is 10,800 gallons which provides more than 30 minutes of detention at the peak day pumping rate at build -out of the project of 251 gpm. The water system is classified as a public water supply by the Colorado Department of Health. Both the quality and bacteriological content of the water has consistently met all parameters of the State of Colorado Primary Drinking Water System. WATER REQUIREMENTS Table 1 enclosed herein indicates the current water requirements for Los Amigos Ranch PUD and the water requirements for Filings 6 to 10. SCHMUESER GORDON MEYER. INC. - June 22, 1999 Mr, Greg Boecker Page 3 The water system will provide both in-house domestic use and outside lawn irrigation uses. Average and peak day demands are calculated for both irrigation and non -irrigation seasons. As noted in Table 1, the water system has been sized to include the service of the Residential Rural lots, should they require service. PROPOSED WATER TER SYSTEM COMPONENTS The proposed water system components to accommodate Filings 6-10 are shown on the Preliminary Plan Master Water Plan Sheet LAU-2. New 10", 8" and 6" transmission and distribution lines will be installed along with fire hydrants and 1" or 1 Y2" water services for each lot. A new steel water tank will be required in the western portion of the project once development proceeds into Filing 9. The CYBERNET computer model was used to calculate pressures and determine required tine sizes throughout the system. Fire flow demands, rather than peak hour demands, govern the design of the system. Lines were sized with the goal of providing a fire flow of at least 500 gpm at 20 psi. This was achieved in all areas. The fire hydrants were placed where they would benefit the most lots. The hydrant layout shown on LAU-2 has been done consistent with discussions with the Carbondale and Rural Fire Protection District, Due to the large line sizes used, pressure differences that would occur under static conditions and peak day demands are negligible. Assuming a mid -tank level, a maximum pressure of about 135 psi would be observed in the lowest portion of Filing 8. Some low pressure levels will occur on the lots in the northeast portion of the project in the vicinity of the water tank. The Water Master Plan Sheet LAU-2 indicates Tots which fall above the elevation 7090140 psi line. The significance is that, depending on where the actual homesite is situated, individual lot owners may wish to install a pump and pressure tank to obtain higher, in-house pressures. One and one-half inch diameter water services are also recommended for these lots to minimize the headloss that would occur from the water main to the house. The attached report entitled, "Los Amigos Ranch PUD Preliminary Plat, Filings 6-10, Water System Calculations" contains a computer model schematic and results of the fire flow analysis. Again, the maximum day pressures listed were virtually the same as the maximums observed under static conditions. Separate fire flow runs are provided for an analysis of the complete system with both tanks on line and "an east tank only" scenario which excludes Filing 9. The existing 320,000 gallon east tank was over -sized to accommodate potential future filings. Considering those areas east of Filing 9 (which has 60 lots) and the water demands referenced in Table 1, the minimum required tank volume can be calculated as follows: SCHMUESER GORDON MEYER. INC. June 22, 1999 Mr. Greg Boecker Page 4 Equalization Fire Flow Emergency EAST TANK 25% average total demand 15002 gpm x 2 hours 35,449 gallons 180,000 gallons 1 average day (domestic) Minimum required volume 63,860 gallons 279,309 gallons 1 Domestic and irrigation 2 Auburn Ridge Apartments only; 500 gpm single family lots. Considering the incremental storage required to serve Filing 9 (60 lots), the minimum size of the western tank can be calculated as follows: WEST TANK Equalization Fire Flow 25% Average total dernandl 5002 gpm x 2 hours Emergency 1 average day (domestic' 9,712 gallons 60,000 gallons 16,200 gallons Minimum required volume 1 Dornestic and irrigation 2 Single family lots RURAL RESIDENTIAL LOTS For purposes of sizing the central water system, service to the four (4) Rural Residential lots was assumed to be part of the water system. Because of the size of these lots and their location relative to the remainder of the project and the water system, this plan proposes as an alternative the ability to drill an individual well on each of these lets. With respect to the history of well development in this area, we have reviewed records available from the District Engineer's Office and have talked to local well drillers familiar with groundwater conditions. Wells have been variable with respect to well depth and well yield. Generally, the wells have been completed in bedrock formations or in the alluvial layers immediately above bedrock interfaces. Well yields are generally less than 10 gpm which would indicate intermediate storage between the well and the residence may be required depending upon total well yield. We anticipate the water would be classified as SCHMUESER GORDON MEYER, INC. June 22, 1999 Mr. Greg Boecker Page 5 "hard", but that all Colorado Primary Drinking Water Standards will be met. Depending on the degree of hardness, water softening may or may not be elected by the homeowner. With respect to fire protection for these lots, it is proposed to provide a 2000 gallon cistern. with draft pipe for use by firefighting apparatus. This cistern would be located near the residence and would be sited at the time that an architectural site plan is available for the residential building construction. 4:92 SANITARY SEWAGE DISPOSAL PLAN EXISTING SANITARY DISPOSAL FACILITIES Previously approved filings within the Los Amigos Ranch PIJD are serviced by either individual sewage disposal systems (lSDSl or a central wastewater treatment collection and treatment system operated by the Spring Valley Sanitation District (SVSD). Those portions of the PUD serviced by SVSD are properties which generally lie within the Spring Valley aquifer drainage and can be serviced by gravity collection sewerlines. The approximate boundaries of the Spring Valley aquifer have been established during prior approvals. CENTRAL WASTEWATER SYSTEM Residential Lots With Central Wastewater Treatment and Collection System Central wastewater treatment and collection services are provided by the Spring Valley Sanitation District (SVSD). The existing system consists of a gravity sewer collection system that serves both Los Amigos Ranch PUD and Colorado Mountain College (CMC), and an aerated lagoon wastewater treatment facility utilizing exfiitration basins as a disposal method for effluent. Within the Los Amigos Ranch PUD, the central sewer system presently services Auburn Ridge Apartments and 49 single-family lots. Proposed Sewer Collection Facilities - Filings 6 thru 10 The wastewater collection system will be extended throughout Filings 6 thru 10 to provide collection of wastewater to an additional 174 single-family lots. Because of the variations in the topography over the extent of the project, the vast majority of these lots will be serviced by a low pressure sewer collection system. This system varies significantly from the traditional gravity sewer collection system typically seen in municipal wastewater collection systems. As opposed to having large diameter sewer gravity pipes discharging to central lift stations, a low pressure sewer collection system utilizes pumping units on individual lots which feed a common small diameter pressure sewer force main. SCHMUESER GORDON MEYER, INC. June 22, 1999 Mr, Greg Boecker Page 6 A number of low pressure collection system alternatives have been investigated by the Owner. The equipment and design methodology as employed a -one sewer systems of Niskayuna, New York, have been used as a reference specification for the system. Attached hereto is a preliminary design for the system directly from e -one and dated May 10, 1999. Sheet LAU-3 of the plans is a plan layout of the entire system. The force mains vary in size from 1 Y2" to 4". The system discharges to the existing gravity collection system of the SVSD. This system is consistent with the recommendations by the County Engineer on the previous submittal for Filings 6 thru 10 and upon which the condition of approval was written requiring a low pressure sewer collection system. It is anticipated that this system will be owned and operated by either the Homeowners Association or SVSD from the point at which the connection is made to the gravity system of the SVSD. Sheet LAU-7 shows a typical pumping system that will be installed by each individual homeowner at the time individual residences are constructed. The homeowner will be required to construct a pumping system that is consistent with the design parameters for the e -one low pressure sewer system, sized in accordance with the wastewater collection requirements of each individual residence. Proposed Wastewater Treatment Facilities - Spring Valley Sanitation District Centra'i treatment will continue to be provided by SVSD. The existing treatment facility is not sufficient in capacity to handle the treatment requirements of Filings 6 thru 10. SVSD is currently involved in the process of expanding the wastewater treatment facilities. An Amended Service Pian has been completed by the District and submitted to the County for review. That Amended Service Plan has been approved by both the Planning and Zoning Commission and the Board of County Commissioners. It will serve as a basis for expansion of wastewater treatment facilities, of which Los Amigos Ranch PUD is a portion. The next step in the evaluation process is the submission of a Site Application through Garfield County to the Colorado Department of Public & Environment CDPHE). Currently, CDPHE is undertaking a 208 Regional Water Quality Management Plan for District 11, which encompasses the Roaring Fork River Drainage Basin. This plan has been completed in draft form and will be presented before the Water Quality Control Commission in August, 1999, for final approval. SVSD is anticipating that, within a week after final approval of the 208 Regional Water Quality Management Plan, the Site Application will be completed and submitted to Garfield County for consideration prior to review by the CDPHE. Completion of construction of wastewater treatment facility expansion will be dependent on the length of approvals by the various review agencies. The potential dates for completion range from the end of the construction season of year 2000 to completion by mid -year 2001. SCHMUESER GORDON MEYER. INC June 22, 1999 Mr. Greg Boecker Page 7 INDIVIDUAL SEWAGE DISPOSAL. SYSTEMS {ISDS) Residential Lots With ISDS ISDS installations are being proposed for the four (4) Rural Residential lots shown on the Amended Preliminary Plat. Referencing the geotechnic report prepared by Hepworth-Pawlak included in this application, there have been nine percolation tests conducted throughout the filing. The percolation test results range from 11 minutes per inch to 40 minutes per inch. These percolation rates are indicative of subsurface conditions which are acceptable for ISDS to be constructed. The percolation tests were run at locations and in site soils conditions that are representative of the overall conditions throughout the project. Additionally, there are ten 10) units within the existing Los Amigos Ranch PUD which have been installed and are using ISDS far sewage service. To the best of our knowledge, adequate percolation and subsurface conditions were found at all these sites for standard ISDS utilization. Environmental and Health Impacts Analysis Garfield County Sewage Disposal Regulations which, in turn, are based on the "Guidelines on Individual Sewage Disposal Systems", Colorado Department of Health, set forth the conditions and regulations under which the County and the State of Colorado have determined are appropriate to the construction of ISDS. These regulations are very comprehensive with respect to site characteristics which determine the type and size of the system which can be constructed. Those regulations recognize the ability of a soil matrix to provide the necessary treatment to septic tank effluent such that, once the effluent passes through the soil matrix, the treated effluent does not pose a public health hazard or risk. The regulations further address the potential for cumulative impact of ISDS systems by specifying the minimum lot sizes that should be utilized for ISDS systems. ISDS technology recognizes that there are certain instances where there are inherent restraints to the use of ISDS's. These restraints include high groundwater table, underlying bedrock formations, inadequate percolation rate, horizontal separation from wells and water courses, and excessive percolation rate. Whenever any of these restraints exist, the regulations require that they be identified and that the system installed when restraints occur, be designed under the direction of a registered professional engineer in the State of Colorado. A "standard" ISDS system, typically consists of a septic tank and leach field. In order to use a standard ISDS, the underlying soil matrix should demonstrate percolation rates within acceptable defined limits and there should be identified no restraints to the installation of the system. As stated above, all systems currently installed within the Los Amigos Ranch PUD are standard systems, with acceptable percolation rates existing and no restraints to construction identified. Based upon data now available, it is anticipated that for the four Rural SCHMUESER GORDON MEYER, INC June 22, 1999 Mr. Greg Boecker Page 8 Residential lots, a standard system will be installed. In each case, percolation tests and profile holes will be excavated at the location and depth of the proposed leach field at each individual building site in accordance with Garfield County regulations. The results of those tests will be analyzed and the system design based on percolation rate and size of residence. Attached to this letter report is a "Management Plan For Individual Sewage Disposal Systems". As stated in the Plan, the purpose is to provide for the regular operation and maintenance of ISDS. This Plan has previously been incorporated into the covenants of Los Amigos Ranch PUD. The Plan will be included in the covenants adopted as part of the Preliminary Plan.. Also attached to this letter report is a letter from Hepworth-Pawlak dated January 19, 1998, which further summarizes the field investigations performed on this site. As stated in the letter, Hepworth-Pawlak reiterates their conclusion from their original study which indicates that this site is suitable for individual septic systems while recognizing that mounding or other engineered systems may be required where a shallow bedrock restraint might be encountered. ROADWAY INFRASTRUCTURE Roadways within this project have been sized in accordance with current requirements of the Garfield County Subdivision Regulations. Estimated service requirements are based on 10 vehicle trips per day (VPD) per individual lot. Typical road sections for the different roadway classifications are contained within the Preliminary Plan drawings. Roadway infrastructure as part of this filing will be as follows (next page): SCHMUESER GORDON MEYER, INC.

We have received a copy of the first 4 pages of preliminary plat review letter by Wright Water Engineers to Garfield County dated January 9, 1998. We performed a preliminary geotechnical study for the project under Job No. 196 617. dated February 14. 1997. Individual Septic Systems: Percolation tests were conducted in January. 1997 to evaluate the feasibility of individual septic systems at the site. The percolation rates varied from 11 to 40 minutes per inch. The average of eleven percolation tests was about 24 minutes per inch. The tests were performed between 3 and 5' IA feet below the ground surface. All the tests were performed in the overburden soils above the basalt flow rock. Partial refusal to digging by the Case 780C rubber -tired backhoe was encountered shallower than 8 feet deep in 15 of 21 pits. The average refusal depth was 4'/a feet. Whether the refusal was on intact basalt flow or on basalt boulders within the overlying basalt colluvium soils could not be determined in the relatively small backhoe pits. Based on our experience in the area and the site geology. we expect that the basalt flow is close to the refusal depths encountered in the pits. The development should be suitable for individual septic systems. Mounding or other engineered systems may be required in shallow basalt rock areas. The system designs should be based on site specific soils information. If you have any questions, please contact our office. Sincerely. HEPWORTH-PAWLAK GE,047 INC. V ` 1F� E. H POs 43 Daniel E.

A set of three maps were prepared in connection with this report. The set of three maps were based on a regional study done by Lincoln-DeVore for Garfield County in 1975 under the provisions of Colorado House Dill 1041. The House Bill 1041 mapping was amended and added to, to prepare the set of reaps for this site, but the set of three maps which accompany this study must still be considered as preliminary in nature. The three maps are: Plate I - Preliminary Geologic Map: Plate II - Preliminary Soils Hazards Zone Map and; Plate III - Preliminary Slope Hazard, Floodway and Stability Map. The scope of this present work consisted of 1) the tracing of the Preliminary Geologic map to a new topographic base map, and 2) the re -issuance of the original letter (dated September 14, 1978) describing the geology and hazards of the site. No addi- tional site reconnaissance was conducted. Geologically the site could be described as an upland mesa, formed by basalt flows (Tb) (see Plate I) which were extruded during the down cutting of the Roaring Fork Valley. These flows covered the Maroon Formation (PPm) (see Plate I), a thick sequence of red interbedded sandstones, siltstones, and shales which can be seen outcropping along the southwestern edge of the site. The basalt flows also partially covered the Eagle Valley Evaporite (Peer) in the southern portion of the site. The Eagle Valley Evaporite locally consists of white to grey gypsum with widely spaced fine grained sandstones and dark grey shales. erode, Sprinot, Cnlorotto Pubo, C_olarodo Grcnd Junction, Colorad Glenwood Sprintr, Colornd3 FvonsWyoming Los Amigos Ranch February 5, 1962 Page -2- The following discussion of the engineering considerations of these three formations is general in nature. The Eagle Valley Evaporite (Pev) has undergone several types of deformation which has resulted in a typical chaotic internal structure. The contortion and deformation of the incompetent materials of this formation dictates that wherever it is exposed it must be considered as potentially unstable. Other hazards associated with this formation include potential solution, hydro - compaction and the presence of corrosive minerals. The maroon Formation (PPm) is highly fractured and, therefore, easily eroded which provides an excellent source of material for rockfall and debris flow, when exposed on steep slopes. These hazards are only present along the steep valley sides on the west and southwest boundary of the site. Soils derived from the Maroon formation may be susceptible to potential subsidence and hydrocompaction. The basalt flows (Tb), which underlie the majority of the site, are dark grey, highly fractured, vesicular basalts attaining several hunderd feet in thickness. The major hazard associated with the basalt is rockfall which is present on the steeper slo- pes below the cliff -like palisades along the Roaring Fork Valley in the west and southwest edges of the site, and along the outcrops near the eastern boundary. Another large rockfall area is present in the south central portion of the site just north of the Colorado Mountain College access road. Another slope stability problem in the presence of a moderate sized landslide (Qls) was noted at the base of the palisade bet- ween the two major drainage gullies just north of where they intersect. This slide appears fairly old and moderately stable but, without specific analysis, should be considered potentially unstable. The palisades which occur throughout the proposed development area should be considered as potentially unstable and a minimum set- back from the edges for buildings should be established prior to construction. The basalt bedrock appears to outcrop or be present at a shallow depth throughout the majority of the site and wherever it is encountered close to the surface will affect both construction. and excavation and may require blasting for removal. The shallow bedrock is highly fractured and permeable, which will affect the potential for individual septic systems and may necessitate the use of a central septic system. Amigos Ranch February 5, 1982 Page -3- Surficial deposits mapped as colluvium (Qc) have potential hazards which are dependent on the formations from which they are derived and their modes of deposition. Colluvium, derived from the Maroon formation, is mainly gravity transported and will be susceptible to potential subsidence due to hydrocompacti.on only, whereas colluvium derived from the Eagle Valley Evaporite will be susceptible to solution, hydrocompaction and the presence of corrosive minerals. Alluvial deposits mapped as terraces (Qt1_2) consist mainly of well rounded sands and gravels and have no inherent hazards except where they overlie incompetent members of. the Eagle Valley Evaporite, which could cause them to be potentially unstable. Sands and gravels also make up the deposit which surrounds the Roaring Fork River labeled (QAL) . The alluvial deposit mapped as (QAL) in the eastern part of the site, however, consists mainly . of sand, silt and clay deposited by stream action. Expansive clays and/or consolidating silts may be encountered in this eastern alluvial area. Another geologic feature mapped as an alluvial fan (Of) was noted just south of the site but will not affect the proposed developement. Two major gullies and several minor ones were inspected to deter- mine their potential for flooding and debris flows. The evidence indicates that significant stream flow in most of the gullies will exist only during and after torrential rains. The upper part of the drainage basins are fairly flat, cultivated, and cross the highly fractured and permeable basalt flows which tends to reduce runoff to a level far below that which would normally be expected; however, the potential for flooding within the gullies does exist and has been mapped as floodways (fw) (see Plate III). The lower partof the drainages become fairly steep and contain considerable quantities of debris. Close inspection of these gullies revealed no recent debris flow activity, and actually very little potential for debris flows. In all the areas of the proposed development which are located on the uplands, the flood hazard to those areas is almost nonexistent. There is a potential for hazards to exist for any roads and darns placed in the area of the gullies; these must be designed for the relevant peak flows and channel configurations. Site specific studies are recommended in areas of proposed construction which contain geologic hazards, at which time speci- fic mitigation procedures can be outlined. The following legend summarizes the geologic units included on the Preliminary Geologic map. 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 Amigos Ranch February 5, 1982 Pane -4-- Qal Qc ALLUVIUM (Quaternary) Stream deposited material.

It should be possible to develop the project as proposed without encountering severe constraint or hazards associated with the geology. Building sites are not recommended in the landslide area or near the faults shown on Fig. 1. Dense hard basalt is expected at relatively shallow depths and difficult excavation conditions should be expected. Subsurface conditions encountered in the exploratory pits excavated in the genera! proposed development area consist of 1 to 3 feet of topsoil overlying nil to 7 feet of clay and silt. About V2 to 3 feet of basalt colluviurn overlying basalt rock was encountered in most of the borings below the clay and silt. The basalt soils were not encountered in Pits 1, 7, 8, 9, 18 and 21 to the maximum depth explored, 9 feet, Groundwater was not encountered in the pits and the soils are slightly moist to moist. Spread footings placed on the natural subsoils and designed for an allowable bearing pressure of 1,500 psfto 3,000 psf appear suitable at the building sites. The footings may need to be designed for minimum dead load if expansive clays are encountered. The report which follows describes our investigation, summarizes our findings, and presents our recommendations suitable for planning and preliminary design. It is important that we provide consultation during design, and field services during construction to review and monitor the implementation of the geotechnical recommendations. If you have any questions regarding this report, please contact us. Sincerely, HEPWORTH-PAWLAK GEOTECHNICAL, INC. 1 1 1 1 Daniel E. Hardin, P.E. Rev.

The project site is shown on Fig. 1. The purpose of the study was to identify the geologic and subsurface conditions and evaluate their impact on the project. The study was conducted in accordance with our proposal for geotechnical engineering services to Greg Boecker, dated December 9, 1996. A field exploration program consisting of a reconnaissance and exploratory pits was conducted to obtain information on the site and subsurface conditions. Samples obtained during the field exploration were tested in the laboratory to determine compressibility or swell and other engineering characteristics of the on-site soils. The results of the field exploration and laboratory testing were analyzed to develop recommendations for project planning and preliminary design. This report summarizes the data obtained during this study and presents our conclusions and recommendations based on the proposed development. PROPOSED DEVELOPMENT The proposed development will consist of 158 lots with an average size of 31/2 acres as shown on Fig. 1. The development will consist of single family homes. Private driveways will access the building sites. We assume the residences will be typical of the area and be 2 stories, possibly with crawispace, shallow basements and slabs -on -grade. The development will be serviced by a central water and individual septic disposal systems. If development plans change significantly from those described, we should be notified to reevaluate the recommendations presented in this report. 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 _ 2 _ SITE CONDITIONS The Los Amigos Ranch PUD is located on the northeast side of the Roaring Fork River valley about miles 5 miles south of Glenwood Springs. The general topography in the area is shown on Fig.]. This study covers 158 single family lots and a 151.9 acre rural residential tract in the western part of the PUD. The Subdivision 2 area in the eastern part of the PUD has already been platted and several residences have been constructed in that area. The proposed home sites and rural residential area covered by this study are located on a rolling upland which lies about 800 feet above the Roaring Fork River valley floor. Slopes on the single family lots usually do not exceed about 10% but steeper slopes are locally present on some lots and in the rural residential tract. The steeper slopes are located along the rim of the upland and along a west trending valley which crosses through the rural residential tract where slopes between 30% and 100% are locally present. Major drainages do not cross through the property The property is drained by several small ephemeral streams with relatively small basins. Vegetation is primarily sagebrush and junipers. GEOLOGIC SETTING The Los Amigos Ranch PUD is located on a roiling plateau to the northeast of the Roaring Fork River valley. The plateau lies about 800 feet above the valley floor and underlain by :Miocene -age basalt flows. The area is on the southwestern edge of the White River Uplift which was formed during the Laramide Orogeny about 40 to 70 million years ago (Tweto and Others, 1978). Local geologic structures are the Cattle Creek Anticline, Glenwood Springs Syncline, and short, small displacement normal faults (Kirkham and Others, 1995). The faults in the area are not considered capable of producing large earthquakes (Kirkham and Rodgers, 1981). Rock formations below the basalt in the area H -P GEOTEcr� 3 are the Maroon Formation, Eagle Valley Formation and Eagle Valley Evaporite. Surficial deposits are predominantly colluvium and a small landslide. FORMATION ROCK Basalt: The basalt below the plateau is made up of multiple flow sheets which are sometimes interbedded with tuffaceous, fluvial siltstone and sandstone, lacustrine claystone, volcanic ash and volcanic breccia. Below the plateau the basalt flow could be as thick as 160 to 200 feet. The basalt is a very hard, dense rock which is usually cut by a complex joint system. Most of the test pits excavated for this study encountered refusal in basalt at depth of less than 6 feet. The basalt in the area is about 22.4 million years old (Kirkham and Others, 1995). Maroon Formation; The Pennsylvanian and Permian -age Maroon Formation is present below the basalt in the western part of the study area. The Maroon is a maroon and grayish -red sandstone, conglomerate, and mudstone. The beds are usually cemented and hard with some non-cemented beds. The rock is usually cut by joints which gives the rock a blocky structure. Eagle Valley Formation and Eagle Valley Evaporate: These two rock units are present below the Maroon Formation in the western part of the study area and may directly underlie the basalt in the eastern part of the study area. Both rock units were deposited in a large evaporite basin during the Pennsylvanian age about 300 million years ago. The Eagle Valley Formation is a transitional unit between the coarse clastic rocks of the Maroon Formation and the mostly evaporitic rocks of the Eagle Valley Evaporite. The Eagle Valley Formation consists of gray and reddish -brown siltstone, shale, sandstone, and carbonate rocks with some local lenses of gypsum, The Eagle Valley Evaporite consists of gray and brown, gypsum, anhydrite, halite and minor potash salts interbedded with fine- grained sandstone, siltstone and claystone, thin beds of carbonate rock and conglomerate. H -P GEOTECH _q The bedding structure in the Eagle Valley Evaporite in most places has been highly deformed because of plastic flow of the gypsum and anhydrite SURFICIAL DEPOSITS Colluvium: In most areas the basalt and underlying sedimentary rocks are covered by colluvium. The test pits indicated that in the proposed building areas the colluvium is shallow and probably does not exceed 10 feet deep. The colluvium in these areas consists of sandy silt and clay with basalt fragments and basalt fragments in a silty sand matrix. Landslide: A small landslide was previously identified by Lincoln DeVore (1978) on the steep hillside in the eastern part of the rural residential tract, see Fig. 1. The landslide appears to be in colluvium. Evidence of recent movement was not apparent, but the area should be considered potentially unstable. GEOLOGIC STRUCTURES Folds: Regional geologic mapping shows that the north trending axis of the Cattle Creek Anticline generally parallels the axis of the Roaring Fork River valley to the south of Glenwood Springs (Kirkham and Others, 1995). The anticline is bordered on the east by the Glenwood Springs Syncline and the axis of the syncline trends through the study area. These two structures are believed to be the result ofevaporite-flow intrusion from the Eagle Valley Evaporite as a result of crustal unloading associated with stream erosion along the river. Some of the deformation appears to have tilted the early Pleistocene river terraces in the area. Faults: Linear escarpments are present in the southwestern part of the study area, see Fig. I , The escarpments appear to be faults which displace the basalt flows. This would H P GEOTECH 1 1 1 1 1 1 1 1 1 t 1 1 1 1 1 1 1 5 indicate that fault movements are younger than about 22.4 million years. The west trending valley in the rural residential tract appears to be a graben between the two faults. The faults could be associated with evaporite-flow deformation and the formation of the Cattle Creek Anticline and the Glenwood Springs Syncline. FIELD EXPLORATION The field exploration for the project was conducted on January 6 and 7, 1997. Twenty-one exploratory pits were excavated at the locations shown on Fig. 1 to evaluate the subsurface conditions. The pits were dug with a Case 780C rubber -tired backhoe. The pits were logged by a representative of Hepworth-Pawlak Geotechnical, Inc. Samples of the subsoils were taken with relatively undisturbed and disturbed sampling methods. Depths at which the samples were taken are shown on the Logs of Exploratory Pits, Figs. 2 and 3. The samples were returned to our laboratory for review by the project engineer and testing. Percolation testing was performed in shallow pits excavated adjacent to about half of the deeper exploratory pits described above. SUBSURFACE CONDITIONS Graphic logs of the subsurface conditions encountered at the site are shown on Figs. 2 and 3. The subsoils consist of about 1 to 3 feet of topsoil overlying nil to 7 feet of sandy silt and clay with basalt fragments. In most of the pits, about '/z to 3 feet of silty sand and gravel with basalt fragments (basalt colluvium) and basalt rock was encountered underlying the silt and clay. The basalt colluvium was not encountered in Pits I, 7,8, 9, 18 and 21. Some of the clay and silt soils were cemented. Digging in the basalt colluvium and basalt rock was difficult due to the material size and hardness and refusal to the backhoe was encountered in the deposit. H -P GEOTECH 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 _6 Laboratory testing performed on samples obtained from the pits included natural moisture content, density, Atterberg limits and gradation analyses. Results of consolidation testing performed on relatively undisturbed drive samples, presented on Figs. 5 to 11, indicate low to moderate compressibility under conditions of loading and wetting. Minor expansion or collapse potential (settlement under constant load) when the samples were wetted was indicated in most of the tested samples. Results of gradation analyses performed on disturbed bulk samples (minus 5 -inch fraction) of the more granular soils are shown on Figs. 12 to 16. The laboratory testing is summarized in Table I. No free water was encountered in the pits at the time of excavation and the subsoils were slightly moist to moist. GEOLOGIC SITE ASSESSMENT It should be possible to develop the project as proposed without encountering severe constraints or hazards associated with the geology. There are, however, some geologic conditions which should be considered in project planning as described below. FLOODING Ephemeral stream channels are present in some of the proposed single family lots and in the rural residential tract. Because of the lot sizes it should be possible to avoid potential flood areas with the building sites. It is recommenced that a hydrologist evaluate the flood potential along the ephemeral drainages. LANDSLIDE AREA The landslide area in the eastern part of the rural residential tract may extend onto parts of three single family home sites which lie to the north, see Fig, 1. It is recommended that building sites not be considered on the landslide. If buildings are planned near the H -P GEOTECH 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 7 landslide, its boundaries should be reviewed in the held to determine appropriate setbacks for buildings. CONSTRUCTION RELATED SLOPE INSTABILITY We do not expect potential problems with construction related slope instability in the proposed development areas if the landslide is avoided and construction is not considered on slopes steeper than about 30%. Recommendations for site grading are presented in the Site Grading section of this report. GYPSUM DEFORMATION AND FAULTS The folds and faults in the area may be associated with evaporite-flow deformation in the Eagle Valley Evaporite. It is uncertain if this deformation is still an active geologic process or if deformation has stopped. To our knowledge there has been no problems with gypsum deformation in western Colorado except in areas where the Eagle Valley Evaporite is near the surface and sinkholes have developed. Sinkholes are not considered to be a potential hazard because of the thick basalt and sedimentary rock cover. If broad regional gypsum deformation is still occurring, it is likely that the deformation is at a very slow rate and should not be a potential hazard. Differential fault creep could be localized along the faults. Because of this it is recommended that building sites not be locate in the vicinity of the faults. EARTHQUAKES The project area could experience moderately strong earthquake related ground shaking. Modified Mercalli Intensity VI ground shaking should be expected during a reasonable service life for the development, but the probability for stronger ground shaking is ]ow. Intensity VI ground shaking is felt by most people and causes general alarm, but results in negligible damage to structures of good design and construction. The faults in the study area, in our opinion, do not increase the seismic potential. All occupied H -P GEOTECH 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 -8 structures in the development should be designed to withstand moderately strong ground shaking with little or no damage and not to collapse under stronger ground shaking. The region is in the Unifof-n Building Code, Seismic Risk Zone 1. Ba sed on our current understanding of the earthquake hazard in this part of Colorado, we see no reason to increase the commonly accepted seismic risk zone for the area. EXACTION DIFFICULTIES Dense, hard basalt is expected to be present at most proposed building sites and along road and utility alignments. Practical backhoe refusal was encountered in most of the exploratory pits at depths of less than 6 feet. Excavations in the basalt in most areas will require ripping and blasting may be needed, PRELIMINARY DESIGN RECOMMENDATIONS The conclusions and recommendations presented below are based on the proposed development, subsurface conditions encountered in the exploratory pits, and our experience in the area. The recommendations are suitable for planning and preliminary design but site specific studies should be conducted for individual lot development. FOUNDATI ONS Bearing conditions will vary depending on the specific location of the building on the property. Based on the nature of the proposed construction spread footings bearing on the natural subsoils should be suitable at the building sites. We expect the footings can be sized for an allowable bearing pressure in the range of 1,500 psf to 3,000 psf. Expansive clays encountered in building areas may need to be removed or the footings designed to impose a minimum dead load pressure on the order of 600 to 1,000 psf to limit potential heave. Nested boulders and loose matrix soils may need treatment such as enlarging footings or placing compacted fill or concrete backfill. Foundation walls should be H -P GEOTECH 9 designed to span local anomalies and to resist lateral earth loadings when acting as retaining structures. Below grade areas and retaining walls should be protected frons wetting and hydrostatic loading by use of an underdrain system. The footings should have a minimum depth of 36 inches for frost protection. FLOOR SLABS Slab -on -grade construction should be feasible for bearing on the natural soils. There could be some post construction slab movement at sites with collapsible matrix or expansive clays. To reduce the effects of some differential movement, floor slabs should be separated from all bearing walls and columns with expansion joints. Floor slab control joints should be used to reduce damage due to shrinkage cracking, A minimum 4 -inch thick layer of free -draining gravel should underlie basement level slabs to facilitate drainage. UIVDERDRAIN SYSTEM Although free water was not encountered in the exploratory pits, it has been our experience in the area that local perched groundwater may develop during times of heavy precipitation or seasonal runoff An underdrain system should be provided to protect below grade construction, such as retaining walls, crawl space and basement areas from wetting and hydrostatic pressure buildup. The drains should consist of drainpipe 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 I% to a suitable gravity outlet. SITE GRADING The risk of construction induced slope instability at the site appears low provided the buildings are located in the less steep parts of the property as planned and cut and fill depths are limited. Cut depths for the building pads and driveway access should not H -P GEOTECH - 10 - exceed about 10 feet. Fills should be limited to about 10 feet deep, especially where they encroach steep downhill sloping areas. Structural fills should be compacted to at least 95% of the maximum standard Proctor density near optimum moisture content. Prior to fill placement, the subgrade should be carefully prepared by removing all vegetation and topsoil, The fill should be benched into the portions of the hillside exceeding 20% grade. The on-site soils excluding oversized rock and topsoil should be suitable for use in embankment fills, Permanent unretained cut and fill slopes should be graded at 2 horizontal to 1 vertical or flatter and protected against erosion by revegetation, rock riprap or other means, This office should review site grading plans for the project prior to construction. SURFACE DRAINAGE The grading plan for the subdivision should consider runoff from steep uphill slopes through the project and at individual sites. Water should not be allowed to pond which could impact slope stability and foundations. To limit infiltration into the bearing soils next to buildings, exterior backfill should be well compacted and have a positive slope away from the building for a distance of 10 feet. Roof downspouts and drains should discharge well beyond the limits of all backfill and landscape irrigation should be restricted, PAVEMENT SUBGRADE The predominant subgrade material encountered along the road alignment is slightly sandy to sandy, medium plastic clay. Based on laboratory testing and our experience, we estimate the clay subgrade has a Hveem Stabilometer "R" value of about 10 which is considered a poor subgrade for support of pavement materials. Basalt rock and highly calcareous soils will also be encountered which are considered fair subgrade conditions for pavement support. Based on our findings, the subgrade throughout the project area can be assumed to have a design 'R' value of 10. The subgrade support of predominant rock areas encountered should be evaluated on an individual basis. The soils H -P GEOrECH can be frost susceptible which could increase the risk of post construction movement. The topsoil and any wet subgrade in drainage areas are unstable for pavement support. In general, the topsoil should be removed. In any soft and wet areas, subgrade improvement be partial stripping and placement of a geotextile and reinforcement mat (such as Tensar SS -1 geogrid) and additional sub -base aggregate could be used. The geotextile and reinforcement mat should be placed according to the manufacturer's specifications. The entire subgrade and any sub -base stabilized areas should be proof rolled with a heavily Loaded wheel vehicle and soft deflecting areas stabilized before placing the pavement base materials. PERCOLATION TESTING Percolation tests were conducted on January 7, 8 and 9 to evaluate the feasibility of infiltration septic disposal systems at the site. The results of the percolation tests are shown on Table IL Shallow Percolation holes were dug adjacent to about half of the deeper exploratory pits at locations as shown on Fig. 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 adjacent exploratory pits shown on Figs 2 and 3. The percolation test rates varied from 11 to 40 minutes per inch with an overall average rate of 24 minutes per inch. Conventional infiltration septic disposal systems appear feasible for the development. Mounding or other engineered systems may be required in shallow basalt rock areas, LIMITATIONS This report has been prepared according to generally accepted geotechnical engineering principles and practices in this area at this time. We make no other warranty either expressed or implied. The conclusions and recommendations submitted in this H -P GEOTECH 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 - 12 - report are based upon the data obtained from the field reconnaissance, review of published geologic reports, the exploratory pits located as shown on Fig. 1, the proposed type of construction and our experience in the area. Our findings include interpolation and extrapolation of the subsurface conditions identified at the exploratory pits and variations in the subsurface conditions may not become evident until excavation is performed. If conditions encountered during construction appear different from those described in this report, we should be notified so that re-evaluation of the recommendations may be made. This report has been prepared for the exclusive use by our client for planning and preliminary design purposes. We are not responsible for technical interpretations by others of our information. As the project evolves, we should provide continued consultation, conduct additional evaluations and review and monitor the implementation of our recommendations. Significant design changes rnay require additional analysis or modifications to the recommendations presented herein, We recommend on-site observation of excavations and foundation bearing strata and testing of structural fill by a representative of the soil engineer.

Practical backhoe refusal. Where shown above bottom of log, indicates that multiple attempts were made to advance the pit. 1. Exploratory pits were excavated an January 6 and 7, 1997 with o Case 780C rubber—tired backhoe, 2. Exploratory pits were located approximately in the field as directed by the client. 3. Elevations of the exploratory pits were not measured. Logs of exploratory pits are drawn to depth. 4. The lines between materials shown on the exploratory pit logs represent the approximate boundaries between material types and transitions may be gradual. S. No free water was encountered in the pits at the time of excavating. Fluctuations in water level may occur with time. 6.

This letter Is based on our review of available published geologic maps and literature, geologic reports prepared by others and our experience. The following paragraphs present our opinions and recommendations concerning the landslide area and the two faults at the subject site. The ranch is located in the southwest part of Spring Valley in Garfield County, Colorado. The Roaring Fork River Valley is below the site to the west. Colorado Mountain College, Spring Valley Campus is to the east. Glenwood Springs is approximately 6 miles to the northwest. Access is from Highway 82 to the Colorado Mountain College Road to Los Amigos Drive. The ranch can be visualized topographically as a gently roiling plateau. An approximately 40 to 60 vertical feet scarp is along the west edge of the plateau that drops down steeper slopes that slope into the Roaring Fork River Valley. Several comparatively broad and shallow drainage basins on the plateau surface converge into narrow drainages at the west edge of the plateau and drain down to the west. The ranch has been used as dry land pasture. Vegetation consists of grasses, weeds and brush with areas of pinion -juniper forest on the plateau. Larger meadows have been cleared of brush and seeded with wheat grass to provide forage. On the steeper slopes to the west, vegetation consists of pinion -juniper forest. Filing No. 8 is in the southwest part of Los Amigos Ranch below and to the CTLITHOMPSON, INC. CONSULTING ENGINEERS 234 CENTER DRIVE ■ GLENWOOD SPRINGS. COLORADO 81601 • (970) 945.2609 1 1 1 west of the plateau surface. The Rural Residential Area Is approximately 152 acres. Plans are to construct an access road and divide the area into 3 Tots. Each lot will be developed as a "homestead". Construction on each lot will likely include a single family residence, guest house, barn and associated out buildings. We reviewed a report titled "Preliminary Geotechnical Study, Proposed Residential Development Los Amigos Ranch P.U.D., County Road 114, Garfield County, Colorado" prepared by Hepworth Pawlak Geotechnical, inc., Job No. 196617, dated February 14, 1997, a report titled "General and Engineering Geology and Soils, Los Amigos Ranch Subdivision, Garfield County, Colorado" prepared by Lincoln DeVore, Job No. GS -999, 2693, dated April 16, 1979 and several letter reports addressing geologic hazards at the site prepared by Lincoln DeVore. We are In general agreement with the location of the landslide and faults identified in the HP Geotech report. We have approximated the locations of the landslide and faults on the attached Figure 1. In our opinion, the landslide Is an ancient feature that is stable In it's present state. For preliminary planning purposes we believe buildings can be sited on the landslide with the following constraints: 1. Building envelopes should be limited to areas with natural grades no sleeper than approximately 10 percent; 2. Excavations should be limited to a maximum depth of approximately 6 feet; 3. Addition of moisture to the slide mass should be minimized. Surface drainage should be enhanced to facilitate the removal of surface run- off from the slide mass. Drainage channels where surface drainage is concentrated or conveyed across or around the landslide mass should be lined to reduce the amount of infiltration. The approximate locations of the faults is shown on Figure 1. These faults may be active. We recommend that buildings not be sited on the faults. It would be appropriate for roadways to cross the faults, however, movement of the faults could result in a need for some amount of regrading. For preliminary purposes we believe a setback of approximately 100 horizontal feet from the faults for the siting of buildings would be appropriate. We understand that building envelopes are to be sited adjacent the top of the vertical scarp along the south edge of the plateau. We recommend a minimum setback for the building envelopes equal to at least the height of the scarp at a point nearest the building envelope. The recommendations presented herein are preliminary and intended to aid the developer in developing the preliminary plat. We are in progress of completing more detailed studies to develop our final recommendations to be utilized in MIR.

This letter describes the site and our survey procedure and presents the results of our radiation survey. The site is located in the southwest part of Spring Valley in Garfield County, Colorado. The roaring Fork River Valley is below the site to the west. Colorado Mountain College, Spring Valley Campus is to the east. Glenwood Springs is approximately 6 miles to the northwest. Access is from Highway 82 to the Colorado Mountain College Road to Los Amigos Drive. The site can be visualized topographically as a gently rolling plateau. Several comparatively broad and shallow drainage basins on the plateau surface converge into narrow drainages at the west edge of the plateau and drain down to the west. The site has been used as dry land pasture. Vegetation consists of grasses, weeds and brush with areas of pinion juniper forest on the plateau. Larger meadows have been cleared of brush and seeded with wheat grass to provide forage. On the steeper slopes to the west, vegetation consists of pinion, juniper forest. The area to be developed is located on the plateau surface. Plans are to develop 158 lots with an average size of approximately 3.5 acres for single family residences. Much of the property will be open space. A rural residential parcel of approximately 150 acres will be in the southwest part of the development. On November 17, 1997 our engineering geologist, Mr. "Liv'' Bowden visited the site and performed a radiation survey. Our survey consisted of spot checking radiation measurements at widely spaced locations across areas to be developed on the plateau. The ground surface was covered with approximately 2 to 4 inches of snow which had melted to leave small patches of bare ground. Our radiation measurements were taken at areas of bare ground to avoid the readings being lowered as a result of shielding by snow cover. The radiation measurements were taken with a Ludlum instruments, Inc. Model No. 19 Micro -R -Meter carried at arms length (approximately 2 feet above the ground surface).

In our opinion, the landslide is an ancient feature that is stable in it's present state. Site specific slope stability analyses should be performed to better define the slide and its affects on (residential lot development) development. We observed potential rockfall hazards below a rock outcrop scarp along the west edge of the plateau. We qualitatively rate the degree of rockfall hazard as low to moderate. Most of the development avoids the rockfall hazard by being sited on the plateau above the hazard. A "rural residential area" is below the rock outcrop. We recommend buildings be sited beyond the rockfall Hazard boundary. A site specific rockfall hazard analysis will need to be performed to establish the rocktall hazard boundary.

FEATURES This report gives estimates of various soil features. The estimates are used in land use Planning that involves engineering considerations. Death to bedrock is given if bedrock is within a death of 5 feet. The depth is based on many soil borings and on observations during soil napping. The rock is either 'Soft' or 'Hard', If the rock is 'Soft' or fractured, excavations can be made with trenching machines, backhoas, or small rippers. If the rock is 'Hard' or oassive, blasting or special equipment generally is needed for excavation. Cemented pars are cemented or indurated subsurface layers +:ithir, a deatt, of 5 fret, Such pars cause difficulty in excavation. Pans are classified as 'Thin' or 'Thick'. A 'Thin' pan is less than 3 inches thick if contin;,oas?y indurated or less than 1$ inches thick if discontinuous or fractured. Exca4 tire., can be .wade by trehchinc mach nes, backhoe,, o:' sn?: r,pGe"s. A 'T•`ick. par is more than 3 intoe thick if continuously indurated or more thaa lE inches thick if discontinuous or fractured, Such a par is sc thick or massive that blasting or special equipment is needed in excetaa.`icn.

Effective management is based on the relationship between the soils and vegetation and water. This report shows, for each soil, the range site; the total annual production of vegetation in favorable, normal, and unfavorable years; the characteristic vegetation; and the average percentage of each species. Only those soils that are used as rangeland or are suited to use as rangeland are listed. An explanation of the column headings in this report follows. RANGE SITE is a distinctive kind of rangeland that produces a characteristic natural plant community that 1. differs from natural plant communities on other range sites in kind, amount and proportion of range plants. The reiationshio betweeen soils and vegetation was ascertained curing this survey; thus, range sites generally can be determined directly fror t'xe soil map. Sol: properties that affect noistare surely and plant nutrients have the greatest influence or the productivity of range plants. Soil reactior, salt content, and a seasonal 3 high nater tette are also imocrtant. TOTAL PRODUCTION is the amount of vegetation that can be expected to grow annually on well managed rangeland that is supporting the potential natural plant community. It in,ludes al: vegetation, whether or not it is Palatable to grazing animals. It includes the current year's growth of leaves, twigs, and fruit: of w•aody plants. It does not include the increase in stet diareter of trees and shrubs. It is ex.'•essed in Pounds pe' acre of sir -dry vegetation far favorable, normal, and unfavorable )'ears.

They alio affect the construction of water impoundments. The kind and abundance of wildlife depend largely on the amour,', and distribution of food, cover, and water. Wildlife habitat can be created or improved by planting appropriate vegetation, by maintaining the existing plant Cover, or by promoting the natural establishment of desirable plants. In this report the soils are rated according to their potential for providing habitat for various kinds of wildlife. This information can be used in manning parks, wildlife refuges, nature stud), areas, and other developments for wild'.-i,fe in selecting Soils that are suitable for establishing, improving, cr maintaining specific eletents of wildlife habitat; and in determining the intensity of management needed for each element of the habitat. The potential of the soil is rated 'Good,' Fair,' 'Poor,' or 'Very poor.' A rating of 'Good' indicates that the element or kind of habitat is easily established, improved, or maintained, Feu or no lisitatir'`1s af`ect management, ant satisfactory results can be esoe;:ted, A rating of `Fair' i di.ates that the element or kind of habitat can be established, improved, or maintained it most places. Moderately intensive management is reouire.d for yetis€actore results. A rating of 'Poor' indicates that limitations are sev'er'e far the designated element or kind of habitat. Habitat can be created, improved, or mairtainet in most Places, but management is difficult and must be intensive.

In report J. the estimated content of organic matter is expressed as a percentage, by weight, of the soil material that is less than 2 millimeters in diameter. The content of organic matter in a soil can be maintained or increased by returning crop residue to the soil, Organic matter affects the available water capacity, infiltration rate, and tilth. It is a source of nitrogen and other nutrients for crops. EROSION FACTOR K indicates the susceptibility of the whole soil (including rocas and rock fragments? to sheet and rill erosion by water. Factor K is one of six factors used it the Universal Soil Loss Equation (11SLE) to predict the average annual rate of sail loss by sheet and rill erosion in tons per acre per year. The estimates are based crir;arilr on percentage of silt, sand, and organic matter (up to 4 percent) and on soi! structure and permeability. Values of K range frog: 0.05 to 0.69. The higher the value, the rano;•e s.yscectibie the soil is to sheet and rill erosion by water. EROSION FACTOR Y,f is like EROS:CA FACTOR K but it is for the fine -earth fraction of the soil.

Deoth to bedroct is given if bedrock is within e depth of 5 feet, The depth is based on many soil borings and on observations during soil mooing. The rock is either 'Soft' or 'Hard'. If the rock is 'Solt' or fractured, excavations can be made with trenching machines, backhots, or small rippers. If the rock is 'Hard' or massive, blastingor sPecia; eouipment generally is needed for. excavation. Cemented pans are cemented or indurated subsurface layers within 8 depth of 5 feet.

The soils are rated 'Good', 'Fair', or 'Poor' as a source of roadfill and topsoil. They are rated as a 'Probable' or 'Inprobatle' source of sand and gravel. The ratings are based on soil properties and site features that affect the removal of the soil and its use as construction material. Normal compaction, minor processing, and other standard construction practices are assumed. Each soil is evaluated to a depth of 5 or b feet. Roadf ll is soil material that is excavated in one place and used in road embankments in another place. In this report, the soils are rated as a source of roadfill for low embankments, generally less than 6 feet high and less exacting in design: than higher embankments. The ratings art fa- the soil material below the surface layer to a death of 5 or 6 feet. It is assumed that soil layers will be mixed during excavating and spreading. any spins have layer': of contrasting suitability within their profile. The report entitled Ergiree-ins Index Properties is also available and it provides detailed information about each soil layer. This information car, help determine the suitability of each layer for use as roadfill. The performance of soil alta' it is stabilized with lime or cement is not considered in the ratir gs.

This report shows, for each soil, the range site; the total annual production of vegetation, in favorable, normal, and unfavorable years; the characteristic vegetation; and the average percentage of each species. Only those sails that are used as rangeland or are suited to use as rangeland are listed. An explanation of the column headings in this report follows. RANGE SITE is a distinctive kind of rangeland that produces a characteristic natural plant community that differs from natural plant communities an other range sites in kind, amount and proportion of range plants. The relationship betweeen soils and vegetation was ascertained during this survey; thus, range sites generally car be determined directly from the soil map. Soil properties that affect moisture supply and plant nutrients have the greatest influence or; the productivity of range Plants. Soil reaction, salt content, and a seasonal high water table ere also important. TOTAL PRODUCTION is the amount of vegetation that car be expected to grew annually on well managed range:ar. that is suoportine the potential natural plant community. It includes all vegetation, whether or not it is ceiatable to grazing animals. :t includes the current year's crouth of :eaves, twigs, and fruits of woody Plants.

After a right ofway has been flagged, we begin by the clearing of trees and brush. Then topsoil is stockpiled or placed at the side of the roadway. After clearing and grubbing a road surface was established by cutting and filling as required. Equipment utilized: Bulldozers. Excavators, Loaders, sheep foot and smooth drum rollers, water trucks, dump trucks, etc. Fills were placed in approximately 1 foot loose lifts and compacted to at least 95 % standard proctor density. The firm ofH-P Geo -tech was hired to establish water vonteaat and compactive effort needed to achieve this. Due to the rocky environment borrow pits were established_ This was necessary to produce fines. Fines were used t4 establish a satisfactory road bed. The borrow pits were then used as a bairn area for clearing debris and a bury pit for oversize boulders. The pits were then covered with sail and revegitated, After a roadbed had been established, utility consul:Won began. Utility trench locations were established. A bulldozer with a 42" ripper followed the aligunent making a trench that was thea filled with water The water truck was equipped with a special nozzle fabricated to eject water directly into the trench, This procedure greatly enhanced the mixing of earth and water for the backfilling procedure. After er the pipe and fittings were placed, the pipe was bedded in a special material free of rocks greater than 34" in size. A 1 foot layer of this bedding was placed and compacted. Compaction procedures were f equenily tvslcd try geo-techs to assure moisture content and soil density. After the bedding procedure was completed additional utilities were then placed and the above mentioned bedding technique was repeated. After all utilities were installed, the remainder of the trench was backfilled using the same method. When the utilities have been constructed, tested, and approved by the proper experts, the road 1 -'n-1 1 CI r r. , r* fA T 1 .ti r�\I 1 +ri l 1-9 r. .., p. .r - I'> APO 'Ie RI 11 ITT Reception#: 734933 12 of 1©/Zee Fee $85POO DocRFee:0,Q4 GARFIELD COUNTY CO bed was reestablished. This is achieved by scarifying, watering, and rolling. Ail top wiling and dean up effort occur at this time. Before gravel placement begins, a proof roll test is performed in the presence ofa geo-tech or engineer. This is accomplished by ubservics the road surfer under the wheels of a fully loaded dap truck or watertruck_ If any movement is noted the area is marked and reworked until the failure is remedied. After the proof roll is approved, the gravel placement will begin A filter fabric was placed between the sub -grade and gravel, It is placed between the sub -grade and the road base to prevent integration. The filter fabric is rolled out in front of the trucks dumping gravel. The fabric is held in place by grade snakes. The grade stakes provide alignment and elevation location. The gravel is manipulated into place by a motor grader, toilers and waxer trucks. The goal i; to achieve 5moothnese, grade, slope, drainage and density to make an all weather surface.

Six density tests were performed and all tests met the Project minimum density of 95% standard Proctor density. The base course was then dug up at the test locations to expose subgrade soil and the depth measured. Again, all locations met or exceeded the minimum required base course depth of 8 inches. During our visit the gravel roadway surface was observed for signs of instability such as rutting, and cracking. No signs of instability were noted. HP Geotech also performed compaction testing and observation during infrastructure construction. These reports have been previously submitted.

Project No. 110 200A Subject: Summary of Construction Observations and Materials Testing, Juniper Drive Roadway Reconstruction, Filing 8, Phase 2, Elk Springs, Garfield County, Colorado Dear Mr. McElwee: Hepworth-Pawlak Geotechnical, Inc. (HP Geotech) provided observation and materials testing services for subgrade and aggregate base course during construction of the above - referenced project. Our field services for the construction began on September 1, 2010 and continued on an as -requested basis through to completion of aggregate base course placement on September 21, 2010. Our services were performed under the direction of the undersigned licensed engineer registered in the State of Colorado. During construction, applicable testing and observation reports were prepared and have been distributed under separate cover. We previously performed an evaluation of the roadway subgrade and presented our findings and recommendations in a report dated July 22, 2010, under our Job Number 110200A. At the time °four September 1 site visit, the existing aggregate base course had been removed and stockpiled. The subgrade soils had reportedly been scarified about one foot deep and then re -compacted using a vibratory pad foot roller. We observed proof rolling of the subgrade using a loaded dump truck. Areas that deflected excessively were marked for repair. We recommended that the marked areas be sub -excavated at least one foot and replaced with compacted granular import or suitably conditioned and compacted on site material as necessary to provide a stable subgrade. On September 7 we observed that the marked areas had been sub -excavated as reconunended, and on September 8 we observed placement of 3 inch minus aggregate base course in progress in some of the sub -excavated areas. On September 13 we observed that the previously sub -excavated areas had been backfilled and compacted. About six additional areas that reportedly exhibited excessive deflection under truck traffic had also been sub -excavated. One sample of the subgrade and one sample of the stockpiled Class 6 aggregate base course were obtained and tested for laboratory Proctor compaction. grain size distribution, and plasticity index. Laboratory test results indicated the aggregate base course was in compliance with CDOT Class 6 Elk Springs, LLC November 18, 2010 Page 2 aggregate base course specifications for the tests performed. Field compaction testing was performed on the subgrade on September 14 which indicated that the subgrade was compacted to at least 95 percent of standard Proctor density (ASTM D 698), in compliance with our recommendations.- No areas of apparent excessive deflection were observed and we judged the subgrade to be suitable for placement of geogrid and aggregate base course as recommended in our previous report. On September 21, we performed field compaction testing at aggregate base course grade which indicated that the aggregate base course was compacted to at least 95 percent of standard Proctor density, in compliance with our recommendations. Based on our observations during the construction and results of our testing, the subgrade and aggregate base course as constructed for the project were in substantial compliance with our recommendations and applicable Garfield County specifications.

This is due primarily to the fact that virtually all of the subdivision improvements, except for the short extension of Kingbird Drive in Filing 9 and the installation of the sewer line in Filing 6A, have already been completed, and secondarily to the fact that the size and design of the Elk Springs project provides for minimal impact to existing vegetation. Removal or addition of trees and other vegetation on individual lots, as well as the maintenance thereof, is considered by the Architectural Control Committee at the time a residence is proposed for construction. Subject to the requirement to create a defensible space around each home, the location of the building envelopes on each lot and architectural guidelines of Elk Springs strongly encourage that all existing vegetation on a lot be retained to the greatest extent practicable. Upon approval of the within Final Plats, and the concurrent dedication of the open space within those Filings, there will be over 1,150 acres of open space within Elk Springs. This open space consists Iargely of broad areas of naturally occurring forest lands or open grassland. These open space areas are kept in their natural condition and no improvements are made, except for the designation of soft surface biking and hiking system within the open space in Filings 1 through 8 will be extended ttothein�open sking paaced�king containedtra in Filing 8, Phase 2, Filing 9 and Filing 10. p To the extent maintenance is required in these natural, open areas, the Elk Springs Homeowners' Association is responsible for such maintenance. There is currently a program in place for the annual treatment of all open space areas for weed control. This program will be extended to the open space areas that are being dedicated to the Homeowners' Association within the subject Final Flats. 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 ELK SPRINGS, FILING GA SUBDIVISION IMPROVEMENTS AGREEMENT THIS ELK SPRINGS, FILING 6A SUBDIVISION IMPROVEMENTS AGREEMENT ("SIA") is made and entered into this day of , 20, by and between ELK SPRINGS, LLC ("Owner") and the BOARD OF COUNTY COMMISSIONERS OF GARFIELD COUNTY, COLORADO, acting for the County of Garfield, State of Colorado, as a body politic and corporate, directly or through its authorized representatives and agents ("BOCC").

Filing 9 This filing consists of the western most lots in Elk Springs. Again, the bulk of this construction was previously completed as documented in the attachments to Dean Gordon's July 25, 2007 letter to you. The exception is that two additional lots (79 & 80) have been added at the top of Kingbird Drive. Necessary future construction consists of widening a portion of the existing drive, extending the drive, constructing a cul-de-sac and installing utility services to the existing mains as shown on the plans. Refer to the attached Filing 9 - Kingbird Drive SIA Cost Estimate. I have reviewed the status of previously -constructed public improvements for this project.

After a right ofway las been flagged, we begin hy the clearing of -trees and brush. Then topsoil is stockpiled or placed at the side of the roadway, After clearing and grubbing a road surface was established by cutting and filling as required. Equipment utilized: Bulldozers. Excavators, Loaders, sheep foot and smooth drum ratters, water trucks, dump trucks, etc. Fills were placed in approximately 1 foot loose lifts and i. umpacted to at bast 95 % standard proctor density. The £irm of 14-P Geo -tech was hired to establish water content and compactive effort needed to achieve this. Due to the mcicy environment borrow pits were established. This was necessary to produce fines. Fines were used to establish a satisfactory road bed_ The borrow pits were then used as a burn area for clearing debris and abury pit for oversize boulders. The pits were then covered with soil and revegitated. After a roadbed had been established, utility consta utiou began. Utility trench locations were established, A bulldozer with a 42" ripper followed the alignment making a trench that was then filled with water The water truck was equipped with a special nozzle fabricated to eject water directly into the trench, This procedure greatly enhanced the mixing of earth and water for the backfilling procedure. After the pipe and fittings were placed, the pipe was bedded in a. special material free of rocks greater than Y/." in size. A 1 foot layer of this bedding was placed and compacted. Compaction procedures were ft eyuently tosEca by gea-techs to assure moisture content and soil density. After the bedding procedure was completed additional utilities were then placed and the above mentioned bedding technique was repeated. After all utilities were installed the remainder oldie trench was backfilled using the same method. When the utilities have been constructed, tested, and approved by the proper experts, the road { r.f,-* Yt Fr, e+ t'. 1 r. 11, T 1 .m.,,1 1 !`1J I-1, T fl .-r 1 4 Eli FA E17,14111 ilitrli17141,11iNSVIAT Oil I, Reception#; 734933 101107200'7 01:26:12 PM Jean AlberiCo 12 of 17 Reo Fee:$86.00 Doc Fee 0.03 GARFIELD COUNTY CO bed was reestablished. This is achieved by scarifying, watering, and Tolima. Ail top soiling and clean up effort occur at this time. Before ,gravel placement begins, a proof roll test is performed in the presence of a geo-tech or engineer. This is accomplished by observing the read surface under the wheels of a fully loaded damp truck or water truck- If ruckIf any movement is noted the area is marked and reworked until tate failure is remedied. .mer the proof roll is approved, the gravel placement will begin. A filter fabric was paced between the sub -grade and gravel. Itis placed between the sub -grade and the road base to prevent integration. The filter fabric is rolled out in front of the trucks dumping gravel. The fabric is held in place by grade stakes. The grade stakes provide alignment and elevation location. The gravel is manipulated into place by a motor grader, rollers and water trucks. The goal is to achieve smoothness, grade, slops, drainage and density to make an all weather surface, .Again a geo-tech is used to assure moisture content and density, Be assured that every effort was made to assure a quality and safe product to the best of our ability.

Six density tests were performed and ail tests met the Project minimum density of 95% standard Proctor density. The base course was then dug up at the test locations to expose subgrade soil and the depth measured. Again, all locations met or exceeded the minimum required base course depth of 8 inches. During our visit the gravel roadway surface was observed for signs of instability such as rutting, and cracking. No signs of instability were noted. HP Geotech also performed compaction testing and observation during infrastructure construction. These reports have been previously submitted. Based on our test results and observations, it appears that the roadway construction should perform as intended. If you have any questions, please call this office.

Juniper Drive Roadway Reconstruction, Filing 8, Phase 2, Elk Springs, Garfield County, Colorado Dear Mr. McElwee: Hepworth-Pawlak Geotechnical. Inc. (HP Geotech) provided observation and materials testing services for subgrade and aggregate base course during construction of the above - referenced project. Our field services for the construction began on September 1, 2010 and continued on an as -requested basis through to completion of aggregate base course placement on September 21, 2010. Our services were performed under the direction of the undersigned licensed engineer registered in the State of Colorado. During construction, applicable testing and observation reports were prepared and have been distributed under separate cover. We previously performed an evaluation of the roadway subgrade and presented our findings and recommendations in a report dated July 22, 2010, under our Job Number 110200A. At the time ofour September 1 site visit, the existing aggregate base course had been removed and stockpiled. The subgrade soils had reportedly been scarified about one foot deep and then re -compacted using a vibratory pad foot roller. We observed proof rolling of the subgrade using a loaded dump truck. Areas that deflected excessively were marked for repair. We recommended that the marked areas be sub -excavated at least one tbot and replaced with compacted granular import or suitably conditioned and compacted on site material as necessary to provide a stable subgrade. On September 7 we observed that the marked areas had been sub -excavated as recommended, and on September 8 we observed placement of 3 inch minus aggregate base course in progress in some of the sub -excavated areas. On September 13 we observed that the previously sub -excavated areas had been backfilled and compacted. About six additional areas that reportedly exhibited excessive deflection under truck traffic had also been sub -excavated. One sample of the subgrade and one sample of the stockpiled Class 6 aggregate base course were obtained and tested for laboratory Proctor compaction. grain size distribution, and plasticity index. Laboratory test results indicated the aggregate base course was in compliance with CDOT Class 6 Elk Springs, LLC November 18, 2010 Page 2 aggregate base course specifications for the tests performed_ Field compaction testing was performed on the subgrade on September 14 which indicated that the subgrade was compacted to at least 95 percent of standard Proctor density (ASTM D 698), in compliance with our recommendations. No areas of apparent excessive deflection were observed and we judged the subgrade to be suitable for placement of gee}grid and aggregate base course as recommended in our previous report. On September 21, we performed field compaction testing at aggregate base course grade which indicated that the aggregate base course was compacted to at least 95 percent of standard Proctor density, in compliance with our recommendations. Based on our observations during the construction and results of our testing, the subgrade and aggregate base course as constructed for the project were in substantial compliance with our recommendations and applicable Garfield County specifications.

RECITALS A. Declarant is the owner of certain real property situate in Garfield County, Colorado, and more particularly described in the Final Plat for Elk Springs Filing 8 Phase 2, a Subdivision of Los Amigos Ranch PUD, ("Final Plat"), filed for public record in the Office of the Clerk and Recorder, Garfield County, Colorado as Reception No. B. Declarant has previously recorded that certain Amended and Restated Declaration of Covenants, Conditions and Restrictions for Los Amigos Ranch Planned Unit Development, Garfield County, Colorado (Amended and Restated Declaration) on February 15, 1991 in Book 799, Page 48 of the Garfield County Clerk and Recorders' records as Reception No., 421306. C. Declarant desires to annex all those properties contained within the Final Plat pursuant to this Supplemental Declaration and thereby subject said annexed properties (hereinafter "Additional Properties") to the Amended and Restated Declaration and the additional covenants, conditions and restrictions set forth below. NOW THEREFORE, Declarant hereby makes the following declaration of annexation of the Additional Properties and declarations of additional covenants and restrictions applicable thereof: ANNEXATION OF ADDITIONAL PROPERTY 1.1 The Additional Properties contained within Elk Springs Filing 8 Phase 2, a Subdivision of Los Amigos Ranch PUD, as more particularly described on "Exhibit A" attached hereto, are hereby annexed pursuant to Article IV of the Amended and Restated Declaration. 1.2 The Additional Properties are hereby made subject to all provisions set forth in the Amended and Restated Declaration. 1.3 The Additional Properties are hereby made subject to the additional covenants, conditions and restrictions set forth in this Supplemental Declaration. ADDITIONAL COVENANTS, CONDITIONS AND RESTRICTIONS 2.1 Minimum Size of Dwellings Every residential dwelling unit constructed on a single family lot shall have a minimum foundation footprint of 2,000 square feet, exclusive of garages, porches and patios. 2.2 Irrigation Single family lots shall not irrigate more than 3,000 square feet of land. 2,3 Individual Sewage Disposal Systems. All single family lots in Elk Springs Filing 8 Phase 2, a Subdivision of Los Amigos Ranch PUD, are allowed to utilize individual sewage disposal systems (ISDS) after obtaining a site specific percolation test to determine whether a standard septic system is acceptable or an engineered system is appropriate or required. Each ISDS shall be designed to minimize tree removal and changes to the natural contours of the land. 2.4 Central Water System All water rights and water facilities which comprise the domestic water delivery system for EIk Springs Filing 8 Phase 2 are owned by the Elk Springs Homeowners Association, Inc. The Association shall have the power to own, operate, maintain, repair and replace the water delivery system and to levy reasonable charges therefor pursuant to Section 4.8 of the Amended and Restated Declaration, and shall have the further power and authority to levy assessments in connection with the ownership, operation, maintenance, repair, and replacement of the domestic water delivery system in accordance with Article V of the Amended and Restated Declaration. 2.5 Pet Control All pets must be kept under strict owner control at all times. No more that one adult dog and no more than an aggregate of three cats and dogs may be kept on a single family lot. The Board of Elk Springs Homeowner's Association has promulgated rules and regulations regarding pet ownership and control, and may levy pet assessments for violations of said rules and regulations. By way of example, owners may be assessed for pets found roaming free of owner control, or disturbing neighbors or wildlife. Said pet assessments are enforceable as set forth in Article V., Paragraph 5.5 of the Amended and Restated Declaration. Nothing contained herein or in said rules and regulations shall limit the right of the Board to modify said rules and regulations, determine a pet is a nuisance and require it's removal from Los Amigos Ranch P.U.D. Properties, nor limit the right of Elk Springs, LLC or any owner of Los Amigos Ranch P.U.D. property to enforce their property rights. 2.6 Fire Protection The Additional Properties are forested with mature pinion and juniper trees. In order to reduce the danger to homes from lightning induced crown fires, all Homeowners shall create a defensible space by thinning trees within 30 feet of their homes so that the crowns of trees are at least 10 feet apart. This defensible space shall be increased as the slope of the Lot increases. For example, homes on 10% slopes should have a minimum defensible space of 35 feet uphill and to the sides and 37 feet downhill. Homes on 20% slopes need a minimum defensible space of 40 feet uphill and to the sides and 47 feet downhill.
