Overview 3.1. Purpose of Preliminary Plan & PUD Amendment The Applicant is seeking approval of a Preliminary Plan and PUD Amendment for the property currently known as the Aspen Valley Polo Club PUD in eastern Garfield County near Catherine Store. The property is now being referred to as "McClure River Ranch", and this application also seeks to memorialize that name change. The subject property is 100.44 acres and is currently zoned PUD with an approved PUD Guide and PUD Plan Map. This consolidated report demonstrates conformance with all applicable submittal requirements, County Codes, Goals and Policies. 3.1.1. Preliminary Plan This Preliminary Plan application can be considered a continuation of the review for the prior PUD Amendment (approved in February 2018), as that application considered many of the materials typically associated with a Preliminary Plan review. In summary, this application is seeking the approval of the following: • The creation of two common -ownership Tracts in Zone District 1, and one common - ownership Tract encompassing all of Zone District 2. • The creation of six private -ownership Lots for mixed-use barns (as allowed per recorded PUD Guide) in Zone District 1. • The creation of one common -ownership Lot for a future clubhouse and the existing McClure Cabin (now relocated and restored) in Zone District 1. • The establishment of all necessary access and utility easements to serve the subdivision of Zone District 1 and future subdivision of Zone District 2. 3.1.2. PUD Amendment This application seeks to revise and replace the recorded PUD Guide and PUD Plan Map. In summary, this application is seeking the approval of the following: • Revise/ add Building Envelopes in Zone District 1 for one additional barn site and to allow more flexibility in building placement. • Revise future Building Areas and road alignments in Zone District 2 to better represent envisioned future design layout. • Request a change in water supply from a community system to individual wells. • Make minor amendments to PUD Guide for clarity, and to transfer 2 units of residential density from Zone District 2 to Zone District 1.

Zone District 2 The property includes a modern greenhouse structure and gardens that were constructed in 2010 and have been in continuous operation for the past nine years growing organic produce. Figure 11: Existing greenhouse and gardens. Nearby to the greenhouse is an existing barn that was used by former property owners for cattle operations. Figure 12: Existing Barn. 17 McClure River Ranch NARRATIVE — November 2019 Apart from the existing greenhouse and barn, Zone District 2 is undeveloped and currently used for agricultural grazing and food production. The area is dominated by two primary vegetation communities: irrigated pasture and cottonwood galleries. Most of the cottonwood galleries are adjacent to the Roaring Fork River where they are associated with smaller quantities of spruce, ponderosa pine, and juniper. Figure 13: Cottonwood galleries along Roaring Fork River. Both natural and diverted water courses exist in Zone District 2. The property's southern boundary approximates the centerline of the Roaring Fork River, except where adjacent to a rather isolated parcel of BLM-administered land. Two primary irrigation ditches serve Zone District 2 including the Middle Ditch (aka Blue Creek Ditch), and the Lower Ditch. There are also several other lateral ditches existing on the property. Wetlands have previously been identified within Zone District 2, and a Jurisdictional Determination for 9.4 acres was made by the Army Corp of Engineers (ACoE) on April 20, 2009 (ACoE File No. SPK -2008 -00253 -CW). This determination has since expired (after 5 years). The wetlands were mapped again in November of 2017, which resulted in a new total of 7.9 acres, and this mapped area is represented on the PUD Plan Map in Appendix R. The Applicant understands that future subdivision and development of Zone District 2 will require a new jurisdictional determination and permit from the ACoE. McClure River Ranch 18 NARRATIVE - November 2019 Figure 14: Typical wetland area in Zone District 2. 3.3.4.3. Overall Property The site is fairly level with an overall east -west gradient of 0.8%, and an overall north -south gradient of 1.0%. A portion of this topographical change is located in a bench that bisects the property from east to west through the property's mid-section. The riparian forest adjacent to the river is composed of a series of undulating channels, presumably created as the Roaring Fork River historically migrated from north to south in the area. The property generally drains from northeast to southwest at an overall grade of 1.4%, changing in elevation approximately 43 vertical feet over a distance of 3070 feet. Surrounding land uses are varied but are primarily rural residential. To the west of the subject property is Blue Creek Ranch PUD, with an overall density of one unit per 1.6 acres, with the development concentrated on 40% of the 81 acres. To the northwest, the Catherine Court property contains 8 dwellings on one acre, primarily consisting of mobile homes. To the north of McClure River Ranch is the CDOT Right -of -Way for Old Highway 82, and State Highway 82, respectively. North of the CDOT ROW is a 40 -acre parcel of agricultural pastureland. To the east lies the Waldorf School, with their school building and associated accessory facilities and playfields. The subject property is bordered on the south by both the RFTA ROW with the Rio Grande Trail, and BLM-administered lands that represent the northern most portion of the area known as The Crown. A high-pressure gas main bisects the property within a 50' easement held by Rocky Mountain Natural Gas Co., Inc (now Black Hills Energy).

Zone District 1— Plan Elements This section provides an overview of the planned improvements within Zone District 1. 4.3.1. Horse Barns & Maintenance Barn The agricultural facilities of Zone District 1 will include six horse barns, providing stalls for approximately 20-30 horses per barn. The horse barns will each be privately owned, and serve as the primary facilities for accommodating, breeding, and training the owner's horses. As identified in the PUD Guide (Appendix S), the barns may also include dwelling units. It is envisioned that each barn could include one 2 to 3 -bedroom dwelling unit, which would be occupied by owners, horse trainers or other employees. Each barn will also include ancillary facilities such as outdoor paddocks and adequate truck/trailer parking and turnarounds. A maintenance barn planned in the northwest portion of the property, and will provide parking and storage for all equipment, machinery, and supplies. The maintenance barn may also include up to three Affordable Housing Units, as provided in the Affordable Housing Plan (Appendix Q). Figure 18: Conceptual barn design. .pt E L E v n Z 1 N R e 11 T - RLE v I. T f 0 µ McClure River Ranch 24 NARRATIVE — November 2019 4.3.2. Polo Fields Two regulation -sized polo fields have been constructed in Zone District 1. Each polo field is approximately 545' x 1030', and each occupies 12-13 acres. The fields were constructed to lie on the natural grade of the property, and each has a sub -surface drainage system. Irrigation water for the fields is supplied from raw water rights from the Basin Ditch, which amount to approximately 2.5 cfs (see Water Rights & Supply, Appendix M). Three newly constructed ponds on the property provide sufficient water storage for irrigation and fire suppression purposes. Figure 19: Polo players on Field 1, summer 2019. int .41 41.408111 -01 4.3.3. Clubhouse Centrally located on the south boundary of Polo Field 1 is a planned clubhouse. This building will be approximately 4800 sf on one level, and will include a kitchen, bar, dining area, men's and women's locker rooms, restrooms, therapy rooms, and a viewing terrace adjacent to Polo Field 1. The clubhouse site will also provide paved parking for approximately 30-40 vehicles. Adjacent to the clubhouse (to the southeast) is the newly relocated and restored McClure cabin. This structure was the original homestead cabin of Thomas McClure, who developed the Red McClure potato. McClure River Ranch 25 NARRATIVE — November 2019 4.3.4. Cabins There are four planned cabins on the west side of Polo Field 1. These are in an existing gambel oak grove and will be field located to preserve trees to the greatest extent possible. In accordance with the Garfield County LUDC, these cabins are considered Single Family Dwellings since they could be occupied on a year-round basis. The cabins are anticipated to have 2 bedrooms and be approximately 1200 sf each. They are currently envisioned to be utilized as employee housing in the summer, and short-term rentals in the winter.

Affordable Housing Per the LUDC, the McClure River Ranch PUD will provide affordable housing mitigation in an amount equal to 10% of the total dwelling units within the subdivision. The maximum number of allowed dwelling units within the McClure River Ranch PUD is 54, therefore, the Developer will provide up to five Affordable Housing Units. Affordable Housing mitigation may be provided as For Sale, Rental, or Off -Site Affordable Housing Units, and mitigation may be provided in any combination of these three alternatives. The Affordable Housing Units will be provided according to the following schedule: Following the completion and issuance of Certificates of Occupancy for every nine (9) dwelling units within the PUD, no building permits for additional dwelling units shall be issued until the issuance of a Certificate of Occupancy for one Affordable Housing Unit within the PUD, OR the provision of one Off -Site Affordable Housing Unit. The detailed Affordable Housing Plan is provided in Appendix Q. 4.5. Access & Circulation Two access points have been constructed for the McClure River Ranch PUD, and both are from Old Highway 82 (frontage road) on the north of the property. The CDOT acceptance letters for these accesses are included with the Traffic Study in Appendix L. These two primary access points from Old Highway 82 help to distribute traffic throughout the community while also allowing for secondary emergency ingress and egress. It is presumed that some of the traffic generated by this project will utilize the County Road 100 signalized access to Hwy 82, while some will utilize Old Highway 82 to the east of the project, connecting to Hwy 82 at Valley Road. All roads within the project have been designed per County standards to support Average Daily Traffic (ADT) at full build out, and meet minimum design criteria for emergency vehicles per County and Carbondale & Rural Fire Protection District Standards. The road system will be located within private access and utility easements. The road circulation pattern has been designed to effectively disperse traffic, thereby helping to minimize traffic volumes on any one road. 4.6. Landscaping The project will provide landscape enhancements with a focus on proper screening, stormwater treatment and recharge, and suitable plant materials with respect to long-term maintenance requirements and reducing potential wildlife impacts. The site and landscape character has been developed to compliment the local environment. Specific landscape elements were designed with respect to climate, aspect, elevation, soil conditions, and proposed uses. The preliminary Landscape Plans are included in Appendix J, and Landscape Standards are included in the PUD Guide in Appendix S. McClure River Ranch 27 NARRATIVE — November 2019 4.7. Utilities All necessary utilities have been installed into the property to support the build out of Zone District 1 and provide future connections for Zone District 2. Domestic water will be provided by seven constructed and permitted wells, as described in the Water Rights & Supply documentation in Appendix M and the Engineering Report in Appendix H. Wastewater will be accommodated using On -Site Wastewater Treatment Systems (OWTS). The Engineering Plans in Appendix I provide design detail on both the domestic water and wastewater treatment systems. The property owner has significant raw water rights from several ditches, including the Basin Ditch, Middle Ditch, and Lower Ditch. These water rights will be maintained and utilized to provide irrigation support for polo fields, common areas, and building lots within the community. Irrigation water for Zone District 1 will be provided by the existing raw water irrigation system with pond storage and the centralized pump station. The Rocky Mountain Natural Gas Co. (now Black Hills Energy) maintains a 50' east -west easement on the property for three gas lines, which will also provide service to each Lot and Tract. Holy Cross Energy underground electric lines have been installed into the property to support the full build -out of Zone District 1 and future connections to Zone District 2. All future electrical service connections within the community will be buried. Communication lines and pedestals have been installed in the property, and all future communication service connections within the community will be buried. 4.8. Construction Phasing Plan Construction for the project will occur in two primary Phases, as described below: Phase 1: (2018 — 2019: NOW COMPLETE) The first Phase of construction included major improvements within Zone District 1. Work completed during this phase included all major earthwork, grading and construction of the polo fields, road (Chukka Trail), ponds, utilities, irrigation and revegetation. Phase 2: (2020) The second Phase of construction will involve the completion of all necessary infrastructure to support the build out of Zone District 1, including paving Chukka Trail, completing some minor remaining work on storm drainage facilities, installing any remaining required shallow utilities, and final landscaping within the Chukka Trail easement. Various individual building permits may also be sought during completion of the infrastructure. McClure River Ranch 28 NARRATIVE — November 2019 4.9. Impact Analysis Per Article 4-203.G of the LUDC, the Applicant shall describe both the existing conditions and the potential changes created by the project, including any potential impact mitigation strategies. 4.9.1. Adjacent Land Use This subdivision proposes up to 14 dwelling units in Zone District 1, and various agricultural buildings and equestrian uses. The proposed subdivision is highly compatible with surrounding land uses and impacts to adjacent land uses have been mitigated through appropriate planning and design. West Side: The proposed overall density of Zone District 1 is 3.5 acres per dwelling unit, which is a much lower density than the adjacent Blue Creek Ranch at 1.6 acres per dwelling unit, and the adjacent Catherine Court at 0.125 acres per dwelling unit. The proposed PUD also places agricultural uses adjacent to existing agricultural fields in the northern portion of Blue Creek Ranch. The two projects are very compatible in terms of contiguous open space and providing a visual open space buffer from Highway 82. North Side: To the north of the subject property is the CDOT Right -of -Way for Old Highway 82, and State Highway 82, respectively. North of the CDOT ROW is a 40 -acre parcel of agricultural pastureland. The proposed subdivision places agricultural open space and three agricultural barns in this area and is therefore compatible with adjacent uses. East Side: To the east lies the Waldorf School, with their school building and associated accessory facilities and playfields. Under the proposed subdivision, land immediately west of the school would remain as undeveloped with a significant cottonwood forest to remain, thereby limiting any potential impacts to the Waldorf School. South Side: The property is bordered on the south by both the RFTA ROW with the Rio Grande Trail, and BLM-administered lands that represent the northern most portion of the Crown. This application does not contemplate development of lands in this area. 4.9.2. Site Features Apart from areas that have been developed to date, the property is dominated by two primary vegetation communities: irrigated pasture and cottonwood galleries. Most of the cottonwood galleries are adjacent to the Roaring Fork River in Zone District 2 where they are associated with smaller quantities of spruce, ponderosa pine, and juniper. Another notable vegetation community is areas of gambel oak groves. These are limited in area, generally occurring on the northern portion of the property and have been preserved through site design. McClure River Ranch 29 NARRATIVE — November 2019 Both natural and diverted water courses exist on the property. The property's southern boundary is along the Roaring Fork River, except where adjacent to an isolated parcel of BLM- administered land. Three primary irrigation ditches also traverse the property including a piped lateral from the Basin Ditch, the Middle Ditch (aka Blue Creek Ditch), and the Lower Ditch. Approximately 7.9 acres of wetlands have been identified in Zone District 2, and the applicant understands that future subdivision and development of Zone District 2 will require a new jurisdictional determination and permit from the ACoE. There are also existing mapped floodplain areas in the southern portion (see PUD Plan Map, Appendix R). The site is generally level with an overall East-West gradient of 0.8%, and an overall north -south gradient of 1.0%. A portion of this topographical change is located in a bench that bisects the property from east to west through the property's mid-section. The riparian forest adjacent to the river is composed of a series of undulating channels, presumably created as the Roaring Fork River historically migrated from north to south in the area. The property generally drains from northeast to southwest at an overall grade of 1.4%, changing in elevation approximately 43 vertical feet. The proposed subdivision of Zone District 1 is planned to preserve most natural site features including vegetation and topography. There are no identified wetlands or floodplains that would be impacted by this proposal, and the proposed plan is designed to work with the natural topography of the site (see Engineering Plans, Appendix I). 4.9.3. Soil Characteristics According to the Garfield County Soil Hazard Profile Map, the subject parcel is not within any Moderate or Major Soil Hazard Areas. There is a nearby area mapped as a Major Soil Hazard Area, which is discussed in further detail in Section 4.9.4 below. (Source Map: Soil Hazard Profile, Study Areas 1, 2, & 3, Garfield County, Colorado; 2-6-02) In 2008 a Geotechnical report was produced by HP Geotech (see Engineering Report, Appendix H). This site was determined to be in the western Colorado evaporite region within the Carbondale collapse center. The report indicates that this creates a long term settling or subsidence rate between 0.5 and 1.6 inches every 100 years, which should have little significant impact on the proposed project. Twelve test pits were dug with a trackhoe with most depths ranging between 8 and 10 feet deep. The soil profile determined by the field exploration conducted on January 10, 2008 shows 0.5 to 3 feet of topsoil overlaying 2 feet of silty sand in Pit 1 and relatively dense, silty sandy gravel containing cobbles and boulders in the remaining pits. This is said to be alluvial deposits. Logs of these exploratory pits and their locations can be found within the Geotech Report. The report also states that judging from Colorado State Engineer's well records this river alluvium consists of rounded gravel -to boulder size rocks in a relatively clean matrix extends to depths of McClure River Ranch 30 NARRATIVE — November 2019 40 to 50 feet. Free water was encountered in some of the pits and groundwater has been known to elevate during seasonal runoff and times of heavy irrigation. Any below grade areas may require an underdrain system and water proofing. 4.9.4. Geology and Hazard According to the Garfield County Slope Hazard Map, the subject parcel is not within any Moderate or Major Slope Hazard Areas. There is a nearby area mapped as a Major and Moderate Slope Hazard Area, which is located off the subject property and across the Roaring Fork River, south of the Rio Grande Trail. This area is a steep hillside and has historically produced small debris flows onto the Rio Grande Trail following significant precipitation events. (Source Map: Slope Hazard, Study Areas 1, 2, & 3, Garfield County, Colorado; 2-6-02) According to the Garfield County Soil Hazard Profile Map, the subject parcel is not within any Moderate or Major Soil Hazard Areas. There is a nearby area mapped as a Major Soil Hazard Area, which coincides with the Major Slope Hazard area as described above. No other Soil Hazard Areas are proximate to the subject parcel. (Source Map: Soil Hazard Profile, Study Areas 1, 2, & 3, Garfield County, Colorado; 2-6-02) The subject site is not located within any known mapped geologic hazard areas, and thus the proposed land use has little consequence of exposure or impact to known geologic hazards. 4.9.5. Groundwater and Aquifer Recharge Areas The drainage plan has been designed to allow for proper infiltration and groundwater recharge. The road (Chukka Trail) has been crowned to drain into sloped grass -lined swales and ditches. These swales and ditches convey runoff to the localized depressions via storm inlets and piping when necessary. Localized depressions will be the main form of retention to provide water quality and promote infiltration. Inlet structures, piping, swales, depression and overflow structures convey runoff through the site. Larger depressions will be used for retention. Overflows will flow toward the lower wetlands to the south. The Engineering Plans in Appendix provide design detail of all stormwater drainage facilities. A Storm Water Discharge Permit has been obtained from the Colorado Department of Public Health and Environment. Best Management Practices have and will continue to be used to mitigate sediment transport and erosion due to storm events. Sediment will be kept out of the neighboring wetlands and Roaring Fork River during construction activities. Temporary BMPs consist of, but are not limited to, silt fence, erosion logs, check dams, storm inlet and drain protection, temporary sediment traps and depressions, berming and surface roughening. These BMPs have been maintained and improved during construction and will not be removed until vegetation has been permanently established. Permanent BMPs will be the storm water retention depressions that will be regularly maintained. Storm sewer inlet sumps will also act as McClure River Ranch 31 NARRATIVE — November 2019 sediment traps that will need to be cleaned out periodically. Storm water will also be routed over and through vegetated areas, when feasible, to provide another level of water quality treatment. This will promote infiltration and filter out pollutants and sediment. 4.9.6. Environmental Impacts 4.9.6.1. Flora and Fauna Vegetation communities on the subject property include oakbrush shrubland (3.0 acres), upland meadow (10.0 acres), irrigated pasture (39.8 acres), cottonwood riparian forest (36.0 acres), ditch (0.4 acres), wet meadow (2.5 acres), herbaceous wetlands (5.6 acres), forested wetlands (1.1 acres), and willow shrubland (2.0) acres. Most significant vegetation on the property will remain intact. The vegetation community with the largest impact will be the irrigated pasture areas, as the majority of these have been converted to agricultural -based equestrian uses, building sites, irrigated open space, and supporting infrastructure. Other areas of impact include the oakbrush shrubland in Zone District 1, of which approximately 1.0 acres has been removed in the creation of Polo Field 1. Wetlands have previously been identified within Zone District 2, and a Jurisdictional Determination for 9.4 acres was made by the Army Corp of Engineers (ACoE) on April 20, 2009 (ACoE File No. SPK -2008 -00253 -CW). This determination has since expired (after 5 years). The wetlands were mapped again in November of 2017, which resulted in a new total of 7.9 acres, and this mapped area is represented on the PUD Plan Map in Appendix R. The Applicant understands that future subdivision and development of Zone District 2 will require a new jurisdictional determination and permit from the ACoE. No impacts to wetlands will occur with the proposed subdivision of Zone District 1. Mule Deer: Development of the subject property is designed to leave large blocks of habitat relatively intact for continued deer use. Deer use of habitats around homesites will likely continue, although at a lower level, and with changed timing of use. Deer would generally find cover in the thickest patches of shrubs, and venture forth into meadows during the evening and nighttime hours. Mule deer use would be modified and more limited, but use of habitats would still likely occur. Deer damage to landscaping can be expected. The large blocks of open space on the property will allow for some refugia for deer, and will help with continued utilization of more fragmented and modified areas of the property. Given the small size of the project, and available habitat in the areas to the south of the property, this project would have insignificant impacts to mule deer populations. Elk: The proposed project would have very minor impacts to elk and elk habitats. Elk use of the property is limited to a few elk during the winter months; nevertheless, the development of this property would cumulatively reduce available winter range habitats within the area. Because the development has significant open space areas, some elk use of McClure River Ranch 32 NARRATIVE — November 2019 the property is likely to continue, but elk use would occur with increased stress levels and likely reduced availability of habitats. Black Bear: Black bear has become a significant wildlife management issue in the State of Colorado. Bears are commonly supplementing their diets by raiding garbage cans, breaking into homes, and becoming a hazard and a nuisance. Habitat in the area around the subject property is dominated by pinyon/juniper woodlands, and Gambel's oak mixed shrublands, which is good habitat for bears. The significant riparian areas along the Roaring Fork River also provide higher -quality habitats. This development would have minor to insignificant impacts on bear populations or bear habitat, but homeowners will be required to use bear - proof trash containers, not feed pets outside or leave pet food outside, and not allowed to plant fruit -bearing trees or shrubs. Wild Turkey: Wild turkeys occasionally occur on the subject property in a small flock of approximately 10 birds. Turkeys forage in the meadows, bringing their chicks in to feed on the copious grasshoppers in the late summer, and seek shelter in the dense underbrush associated with the property. The turkeys generally keep to the cottonwood forests adjacent to the Roaring Fork River, and associated wetlands near Middle Ditch. The large ponderosa pine trees (Pinus ponderosa) on the property provide excellent roost trees. In general, the property provides a good array of habitats to support wild turkey. The proposed development of Zone District 1 will not have any impact to these primary turkey habitats in Zone District 2. After development, the main impact to turkey would be dogs. As turkeys are ground -nesters, their nests would be extremely susceptible to predation from domestic dogs, and their chicks would also be very susceptible to dog predation and harassment. 4.9.6.2. Designated Environmental Resources Ute Ladies' -tresses (Spiranthes diluvialis) is a native orchid that was listed by the US Fish and Wildlife Service (USFWS) as a Threatened Species in January of 1992. At that time, the species population was estimated at 6,000 individuals in 10 extant and 7 historical sites in the states of Nevada, Colorado, and Utah and thought to be extremely vulnerable. In addition, the habitat of this plant was thought to be threatened from development, noxious weeds, and some grazing practices. As of 2005, Ute Ladies' Tresses were known to occur in 7 western states and population numbers were then estimated at 83,000. In 2004, the USFWS initiated a review to begin the process to take this species off the Endangered Species List as the increased population numbers in combination with additional data regarding the availability of habitat led the USFWS to believe this plant did not need the extra protections the Endangered Species Act. A population of Ute Ladies' -tresses has been identified within the subject property and is located in a portion of the wetland areas in Zone District 2. In 2009, a management plan was created which will provide guidance for future management of the species as development McClure River Ranch 33 NARRATIVE — November 2019 of the property occurs. (Ute Ladies' Tresses Orchid Management Plan for TCI Lane Ranch; Rocky Mountain Ecological Services; July 2009). The Plan includes a mapped "Management Area", and this subdivision of Zone District 1 does not propose any development impacts to those areas. 4.9.6.3. Impacts on Wildlife and Domestic Animals The following section discusses considerations to minimize the potential impacts to wildlife from the proposed development. Many of these recommendations are considered to be "best management practices" for wildlife, which would allow for continued wildlife use of areas within the development. Lighting: Because the area will likely receive use by mule deer and elk during the night, nighttime lighting of the property and excessive lighting of roads (beyond what is required for safe driving conditions) is not recommended. Fencing: In order to continue the effective use of the area by big game animals, wildlife - friendly fencing will be utilized. Fencing that is needed to keep pets and children within private yards encouraged. Landscaping & Revegetation: Because the area is used as winter range, reclamation of road cuts, infrastructure routes and open spaces will occur using similar native plant species and vegetation profiles. Revegetation will also occur as soon as possible; however, planting in the spring after big game have left the area will be best as newly planted materials would likely be browsed first, and plants with little time to set roots will likely be pulled up by grazing big game. Noxious weeds will be treated in order to minimize their spread and impact on winter range and increase the success of revegetation activities. Domestic Dogs: Dogs can have a significant impact on wildlife and the ability for wildlife to effectively use otherwise -available habitats. Dogs can chase and kill wildlife, or so exhaust and injure wildlife that it dies later. To minimize the impacts of dogs on wildlife, the following practices will be employed: 1) Dogs will not be allowed outside of fenced yards unless under leash control. 2) Any fenced enclosures constructed for the overnight maintenance of dogs or cats will be within building envelopes. 3) Loose dogs will be prohibited. Domestic Cats: Domestic cats can have significant impacts on local breeding bird, small mammal, amphibian, and reptile populations in area habitats. Keeping cats indoors will protect a major component of the potential non -game wildlife use in the area. McClure River Ranch 34 NARRATIVE — November 2019 Impacts to Landscaping: Since the subject property occurs within mule deer and elk Winter Ranges, there will likely be damage and use of the landscaping by foraging big game. The individual property owners will be informed of this with the understanding that that Colorado Parks & Wildlife does not provide game -damage reimbursement for damage to landscaping. Bears: There are existing problems with bears, garbage, and people in Garfield County and some bears have shown signs of habituation and aggression towards residents. These conflicts can be minimized by implementation of appropriate mitigation measures. The following measures will be implemented to reduce potential bear problems: 1) There should be no dumps that have edible materials associated with construction and post -construction activities. 2) Residential garbage should be placed in bear -proof dumpsters, individual bearproof trash containers, or kept in trash cans inside closed buildings. 3) Pets should not be fed outside. 4) Bird feeders and hummingbird feeders should be brought in during the evenings and removed altogether during the fall months (September through late November). 5) Nut, fruit, or berry -producing trees or shrubs should not be used in landscaping in order to minimize an attractant for bears around homes and developed areas. 6) Compost piles should be discouraged or prohibited. Birds: Many bird species utilize the area; therefore, the following recommendations are presented: 1) Pet cats should remain indoors, as cats will readily prey upon these species and can have a significant impact on bird use in the area and on bird populations. 2) Bird feeders are discouraged during spring, summer, and fall months due to the black bear use in the area. Bird feeders can be used in the winter (from mid- November through mid-March), as bears are hibernating during this time. 3) All bird feeders, including hummingbird feeders, should be hung away from any window or deck, be at least 10 feet from the ground, and be suspended between two trees or posts. Any seed feeders should have a seed catchment pan to catch discarded seed. 4.9.6.4. Potential Radiation Hazard Eighty percent of counties in Colorado are at high risk for radon, including Garfield County. Radon is an odorless, tasteless, colorless gas that results from the radioactive decay of uranium in the soil. Garfield County's 2010 -2011 radon program indicated that 44% of homes tested had radon values above the EPA's "Action Limit" of 4 pCi/L (pico-curies/liter). (Source: Garfield County website) McClure River Ranch 35 NARRATIVE — November 2019 A gamma radiation survey was conducted on the property on February 22, 2007 by Yeh & Associates, Inc. Gamma radiation measurements were taken on an approximate 500 -foot grid within 3 feet of the ground surface and at the ground surface at grid points. The 33 readings taken on the property ranged from 8 to 16 micro -roentgens per hour (IJRIhr) using a range selector of 25 IJRIhr. The readings averaged 11 IJRIhr. The survey determined that these background readings are typical in this area and that mitigation of naturally occurring radioactive material (NORM) should not be required in the project area. However, areas of deep excavation may encounter materials with elevated levels of NORM. Additionally, in Colorado buildup of radon gas in unacceptable levels often occurs in residential structures that are sealed to minimize air exchange. Passive and active mitigation procedures are commonly employed in this region to effectively reduce the buildup of radon gas. While the survey found that radon gas will not present a significant hazard at this site, if the occurrence of radon is of concern, it is recommended that a building be tested and monitored after construction and commonly utilized techniques employed to reduce the risk. Build-up of radon gas can usually be mitigated by providing frequent exchange of air within the structure and sealing joints and cracks adjacent to the subsoils. 4.9.7. Nuisance The proposed uses within the subject property are not expected to produce any abnormal toxic or noxious substances, smoke, odors, gas, wastes, steam, or dust. Detailed erosion control and construction plans will guide development of the site during all construction phases, with a goal of minimizing particulate matter (fugitive dust) emissions from the project site. Nevertheless, there will likely be a minor increase in airborne particulate matter as a result of equipment operations producing fugitive dust during construction access improvements, vegetation clearing, and during the earthwork phases of construction. To mitigate these impacts, contractors will employ dust control, and CDPHE stormwater permitting will require the removal of mud from vehicles before they track mud onto local roads. The proposed land uses are anticipated to integrate well with neighboring existing land uses. For the above stated reasons, the land use is considered to have minimal nuisance impacts on adjacent lands and is generally consistent with those adjacent uses and their associated impacts. 4.9.8. Hours of Operation Zone District 1 consists primarily of agricultural -related land uses, and as a result most activity will occur during daylight hours on both weekdays and weekends. Some special events will occur primarily in the summer months and may include polo matches or various community gatherings. These special events are also likely to occur in daylight hours, with parking management plans employed to effectively coordinate all vehicular parking needs.

Wildlife: The property owner and / or operator of Zone 1 shall comply with the following requirements and recommendations by Colorado Parks and Wildlife: a) Fencing should be held to a minimum and any necessary fencing should be wildlife friendly. Details and specifications for wildlife friendly fencing can be found at: https://cpw.state.co.us/Documents/LandWater/PrivateLandPrograms/Fencing WithWildlifelnMind.pdf i. Additionally, CPW encourages the applicant to work with adjacent landowners to replace current perimeter fencing with wildlife friendly options. Response: The applicant has coordinated with CPW on the fencing program, and the fencing has been installed in Zone District 1 to a CPW approved specification of 18" height to bottom rail, and a 45" top rail height. This modified specification was approved by CPW in an email from Taylor Elm (CPW) to Jon Fredericks on March 11, 2019. b) Landscaping designs should preclude berry, fruit, or nut producing trees and shrubs to reduce attractants for bears and other wildlife. Homeowners should be aware that CPW is not liable for any damage to landscaping from wildlife. McClure River Ranch 39 NARRATIVE — November 2019 Response: The applicant has provided Landscape Plans (Appendix J) that preclude all berry, fruit or nut producing plant material. This restriction will also be memorialized as a Plat Note on the Final Plat. c) All trash, horse grain/feed, and food -related items should be stored indoors or within bear -proof containers. Eliminating attractants for bears and other wildlife will reduce conflicts. This is especially relevant given that this property lies within the river corridor which is used heavily by various animal species. Response: The applicant has maintained to property pursuant to the above condition. This restriction will also be memorialized as a Plat Note on the Final Plat or within the final Covenants at the time of Final Plat. d) Proposed ponds should be constructed with at least one bank having a minimum slope of 3: 1, preferably 5: 1, to allow ingress and egress of wildlife. If plastic liners are to be used, a minimum of 18 inches of topsoil should be used on top of liners. Response: The three storage ponds in Zone District 1 have been constructed in compliance with the above specification. e) Trails through riparian habitats should be minimized to the extent possible and provide adequate signage to keep users on designated routes. Response: No trails have been developed in riparian habitats and are not contemplated by this application. Trails in these habitats will be applicable to future subdivision and development of Zone District 2. 12. Internal Roadway Design: The internal roadways shall be built to meet, at a minimum, the dimensional requirements of Section 7-107 of the LUDC, as amended, and as represented in the PUD Plan to accommodate full build -out of the PUD. Response: The roads within the project have been designed to County standards, including a 24' paved width in Zone District 1 and 22' width in Zone District 2 (future) based on the projected Average Daily Traffic at full build -out. The Engineering Plans (Appendix 1) provide design detail on road design for Zone District 1, and the PUD Plan Map (Appendix R) provides typical road cross sections for both Zone Districts. 13. Phasing / Timing: Based on the proposed build out schedule (2018-2019 for Zone 1, and 2019- 2020 for Zone 2) and this representation that the development timeframe is less than 3 years, a Development Agreement is not required at this time for vested rights. As a Development Agreement to vest rights in excess of 3 years has not been proposed, the Preliminary Plan for McClure River Ranch 40 NARRATIVE — November 2019 the subdivision of the PUD as proposed shall be submitted and deemed Complete within 3 years from the date of PUD approval by the BOCC. As a part of the Subdivision submittal a new phasing schedule, if necessary, may be presented and reviewed for the subdivision buildout. Response: As this application for subdivision is being submitted within three years of the aforementioned PUD Amendment, this condition has been met. No specific timeframe has been determined for the ultimate subdivision of Zone District 2, however at this time it is expected to occur within the next three years. 14. Residential Development — Zone 2: No residential development shall occur in Zone 2 prior to approval of a subdivision Final Plat. Response: No residential development will occur within Zone District 2 until approval of a subdivision Final Plat for that Zone District. This condition has been memorialized as Plat Note #1 on the Preliminary Plan in Appendix N. 15. OWTS Flow Monitoring: The size of the eastern proposed OWTS within Zone 1 serving the clubhouse is very close to the 2000 gallon per day limit for a public water system under CDPHE. As a result, a water infow meter(s) shall be installed on the buildings served by this OWTS. The records from this water inflow meter(s) shall be available for inspection to verify that the System is handling 2000 gallons per day or less. Response: The clubhouse and associated OWTS has not yet been constructed, however this condition will be followed at the time of construction. 16. Storage and Application of Hazardous Materials: Due to the proximity of the residential development and large fields to the wetlands and Roaring Fork River, the property owner(s) and operators shall apply all fertilizers, pesticides, and other chemicals in accordance with manufacturer recommendations in order to prevent contamination of public water resources. In addition, these chemicals shall be stored appropriately and in accordance with all laws and regulations. Response: Although such use is very limited, all fertilizers, pesticides, and other chemicals are applied in accordance with manufacturer recommendations. No such chemicals are currently stored on site. 17. Radon: All of Garfield County is considered at high risk for radon. As a result, all buildings with ground floor residential and / or commercial occupancy and are enclosed and conditioned (excluding barns, greenhouses, and storage/maintenance buildings) shall be designed and built with Radon Resistant Construction. McClure River Ranch 41 NARRATIVE — November 2019 Response: This condition will be addressed with each new building permit application. 18. Wastewater Treatment Facilities (WWTF): Once a WWTF is established within the PUD, no new OWTSs shall be permitted. At the time a WWTF is available and an OWTS is being replaced or expanded within either Zone 1 or Zone 2, the residential and/or commercial uses served by that OWTS shall connect to the WWTF. Response: This condition is memorialized as Plat Note #2 on the Preliminary Plan (Appendix N) and in Section 5.3 of the PUD Guide (Appendix S). 19. Water System: All water permitting, monitoring and testing shall remain in good standing with CDPHE as a non-public community water system or a community water system, as appropriate. Response: Since this PUD Amendment is seeking a change in the water supply system for Zone District 1, this condition would only apply to a future water system in Zone District 2. Conditions Applicable at Time of Subdivision 20. Wildlife: The following recommendations by the CPW shall be added to the Codes, Covenants and Restrictions for the subdivision: a) Fencing should be held to a minimum and any necessary fencing should be wildlife friendly. Details and specifications for wildlife friendly fencing can be found at: https://cpw.state.co.us/Documents/LandWater/PrivateLandProgra ms/Fencing WithWildlifelnMind.pdf i. Additionally, CPW encourages the applicant to work with adjacent landowners to replace current perimeter fencing with wildlife friendly options. Response: The applicant has coordinated with CPW on the fencing program, and the fencing has been installed in Zone District 1 to a CPW approved specification of 18" height to bottom rail, and a 45" top rail height. This modified specification was approved by CPW in an email from Taylor Elm (CPW) to Jon Fredericks on March 11, 2019. McClure River Ranch 42 NARRATIVE — November 2019 b) Landscaping designs should preclude berry, fruit, or nut producing trees and shrubs to reduce attractants for bears and other wildlife. Homeowners should be aware that CPW is not liable for any damage to landscaping from wildlife. Response: The applicant has provided Landscape Plans (Appendix J) that preclude all berry, fruit or nut producing plant material. This restriction will also be memorialized as a Plat Note on the Final Plat. c) All trash, horse grain/feed, and food -related items should be stored indoors or within bear -proof containers. Eliminating attractants for bears and other wildlife will reduce conflicts. This is especially relevant given that this property lies within the river corridor which is used heavily by various animal species. Response: The applicant has maintained to property pursuant to the above condition. This restriction will also be memorialized as a Plat Note on the Final Plat or within the final Covenants at the time of Final Plat. d) Proposed ponds should be constructed with at least one bank having a minimum slope of 3:1, preferably 5:1, to allow ingress and egress of wildlife. If plastic liners are to be used, a minimum of 18 inches of topsoil should be used on top of liners. Response: The three storage ponds in Zone District 1 have been constructed in compliance with the above specification. e) Trails through riparian habitats should be minimized to the extent possible and provide adequate signage to keep users on designated routes. Response: No trails have been developed in riparian habitats and are not contemplated by this application. Trails in these habitats will be applicable to future subdivision and development of Zone District 2. 21. Public Road Dedication: At the time of subdivision, all roads within Zone 1 and Zone 2 of the PUD shall be dedicated to the public on the subdivision plat. Response: The roads have been designed within Access & Utility Easements as depicted on the Preliminary Plan (Appendix N) and the PUD Plan Map (Appendix R). The minimum easement width in Zone District 1 is 60' and in Zone District 2 is 50'. These easements will be recorded on each Final Plat with a Plat Note including the right of appropriate public and private utility companies to utilize access and utility easements as utility easements, and the right of all emergency vehicles to make use of such access and utility easements in all reasonable circumstances. McClure River Ranch 43 NARRATIVE — November 2019 22. Well Sharing Agreement: The well to be used for the development is proposed to be shared. At the time of subdivision a legal mechanism shall be executed to allow for the physical and financial sharing of the well between all users. Response: Two of the existing wells are planned to be shared: Well No. 6 will be shared with Lot 6 and the maintenance barn on Tract B; and Well No. 7 will be shared with Lot 7, the four cabins in Tract A, and Zone District 2 (future). Well sharing agreements for these two wells will be prepared and recorded with Final Plat. 23. Wastewater Treatment Facility (WWTF): a. The LUDC prohibits OWTSs on lots that are 1 acre or less in size. As a result, should the future subdivision consist of residential and/or commercial lots that are less than 1 acre in size, then these uses shall be accommodated by a centralized Wastewater Treatment Facility (WWTF). b. Should a WWTF be developed within the PUD, then the Facility shall be sized appropriately to accommodate all residential and commercial uses from Zone 1 and Zone 2. c. A note requiring connection to the WWTF at the time of OWTS replacement or expansion within Zone 1 or Zone 2 shall be added as a plat note on the Final Plat, and within the Codes, Covenants and Restrictions. Response: This condition is memorialized as Plat Note #2 on the Preliminary Plan (Appendix N) and in Section 5.3 of the PUD Guide (Appendix S). 24. Affordable Housing Agreement / Plan: At the point 15 or more lots are created through subdivision, as defined in Article 8 of the LUDC, the development is required to provide Affordable Housing. As a result, at the time of Preliminary Plan submittal to create 15 or more lots, the property owner shall submit an Affordable Housing Agreement / Plan in conformance with the PUD Guide and Article 8 of the LUDC. The Agreement / Plan shall be reviewed, accepted, and executed by the property owner and BOCC. Response: While this subdivision application only contemplates the creation of 10 total lots and tracts, an Affordable Housing Plan (Appendix Q) has been prepared in anticipation of the future subdivision of Zone District 2 ultimately creating 15 or more total lots within the PUD. 25. Wetlands: It is understood that disturbance to some jurisdictional wetlands will occur at the time of development of Zone 2. In addition, while it is understood that these required permits from the Army Corps of Engineers were obtained previously, these permits have since expired. As a result, the Applicant shall update the wetland delineation for the properties and obtain all McClure River Ranch 44 NARRATIVE — November 2019 necessary permits as required by the Army Corps of Engineers prior to submittal of the first Final Plat. Response: All of the known wetlands are located within Zone District 2. The wetlands were most recently mapped in November of 2017, which resulted in a total of 7.9 acres, and this mapped area is represented on the PUD Plan Map in Appendix R. The Applicant understands that future subdivision and development of Zone District 2 will require a new jurisdictional determination and permit from the ACoE. 26. Storage and Application of Hazardous Materials: Due to the proximity of the residential development and large fields to the wetlands and Roaring Fork River, the property owner(s) and operators shall apply all fertilizers, pesticides, and other chemicals in accordance with manufacturer recommendations in order to prevent contamination of public water resources. In addition, these chemicals shall be stored appropriately and in accordance with all laws and regulations. Provisions requiring responsible application and storage of chemicals shall be incorporated into the Codes, Covenants, and Restrictions at the time of subdivision. Response: Although such use is very limited, all fertilizers, pesticides, and other chemicals are applied in accordance with manufacturer recommendations. No such chemicals are currently stored on site. This restriction will also be memorialized as a Plat Note on the Final Plat or within the final Covenants at the time of Final Plat. 27. Anglers Easement: At the time of subdivision, the property owner shall provide a public fishing easement along the Roaring Fork River to extend the angler's easement at Blue Creek Ranch. Response: As this potential easement is located within Zone District 2, this condition will be addressed at the time of future subdivision for that Zone. 28. Southeast BLM Parcel: As part of the public improvements to be constructed by the Applicant and secured in the Improvements Agreement as part of the Final Plat Application, the Applicant shall construct a wildlife friendly fence to help prevent disturbance of the Ute's Ladies Tresses on the BLM parcel adjacent to the southeast portion of the development. Response: As this proposed fence is located within Zone District 2, this condition will be addressed at the time of future subdivision and development for that Zone. 29. 100 -Year Floodplain: At the time of Preliminary Plan submittal, the applications shall include an analysis of the level of conformity with the proposed subdivision and the Floodplain Development Permit (Land Use Change Permit for Development within the Floodplain) issued under Resolution 786310. Should the proposed development conform with this Floodplain Development Permit, then this approval shall remain valid. Should the proposed subdivision not McClure River Ranch 45 NARRATIVE — November 2019 conform to this Floodplain Development Permit, then the applicant will be required to either obtain a new Floodplain Development Permit or amend the existing approval. Response: As the existing Floodplain Development Permit only covers lands within Zone District 2, this condition will be addressed at the time of future subdivision and development for that Zone. 30. Offsite Improvements: At the time of subdivision, the Applicant's engineer shall provide a traffic study that addresses the need for improvements on the south side of the intersection of County Road 100 and Highway 82 including the median and right turn lane, and based on traffic counts from the proposed subdivision. The traffic study shall include an analysis of the difference between the cost of improvements and the anticipated revenue from the project's traffic impact fees for consideration at the time of subdivision. Response: Section 12.0 of the Traffic Study in Appendix L provides a detailed discussion that addresses the needs for improvements on the south side of the intersection of County Road 100 and Highway 82. This discussion includes an estimate of the total costs of improvements ($116,500), the total estimated traffic impacts fees of McClure River Ranch at full build out ($147,544), and the proportional share of the subdivision based on all future traffic volumes ($3495 to $4660). The estimated County Road Impact Fees will be more than sufficient to pay for and/or offset the road impacts created by the McClure River Ranch project. McClure River Ranch 46 NARRATIVE — November 2019 5. PUD Amendment 5.1. Summary of PUD Amendment The existing PUD approval was granted in February of 2018, and this amendment proposes to make several revisions to the current PUD Guide and PUD Plan Map. The proposed revisions are described in this Section 5.1. 5.1.1. Zone District 1 - Building Envelopes The recorded PUD Plan Map shows "Building Areas", and these areas have been further refined and defined as proposed platted Building Envelopes for Zone District 1. In many cases, the proposed Building Envelopes are much smaller than the approved Building Areas. In some cases, the proposed Building Envelopes have been expanded slightly from the approved Building Areas to allow more flexibility in building placement. However, in all cases the general layout of the proposed Building Envelopes is very consistent with what was approved in 2018. This proposal also includes one additional Building Envelope to accommodate one more barn in the northwest corner of Zone District 1. No proposed Building Envelopes occupy any areas of environmental sensitivity or would result in additional loss of existing vegetation. 5.1.2. Zone District 1 - Water Supply The existing PUD Approval included plans for a community water system based on the production of one well (now Well No. 7). This amendment seeks to change the water supply for Zone District 1 to individual wells. Seven wells have been permitted and installed on the property to serve the buildout of the entire PUD (see Water Rights & Supply, Appendix M). The well summary is as follows: 5.1.2.1. Table 4: Existing Domestic Water Supply Wells. Well No. Location Serves 1 Lot 1 Lot 1 2 Lot 2 Lot 2 3 Lot 3 Lot 3 4 Lot 4 Lot 4 5 Lot 5 Lot 5 6 Lot 6 Lot 6 & Maintenance Barn in Tract B 7 Lot 7 Lot 7, Cabins in Tract A & Zone District 2 (future) Each well has been tested and is adequate in both production and water quality. Corrosivity was analyzed for each well with results included in the Colorado Analytical Laboratories reports. The water at all the wells tested as non -corrosive. Corrosivity was assessed from the pH and McClure River Ranch 47 NARRATIVE — November 2019 Langelier Saturation Index. A pH of lower than 6.5 or higher than 8.5 can indicate corrosivity. The Langelier Index is calculated using the pH, alkalinity, calcium concentration, TDS, and water temperature. A Langelier Index in the range of -1 to +1 has a relatively low corrosion impact on metallic components of the distribution system (Source: http://www.mae.gov.nl.ca/waterres/quality/drinkingwater/langlier.html). Pump test reports and water quality reports of each well are in the Engineering Report in Appendix H. 5.1.3. PUD Guide Revisions Proposed minor revisions to the PUD Guide are intended to provide clarity and more closely anticipate desired future use of the property, as follows: • Density Transfer. The PUD is currently approved for up to 54 total dwelling units with 12 DUs in Zone District 1 and 42 DUs in Zone District 2. This application seeks to transfer two units of density from Zone District 2 to Zone District 1, without modifying the 54 total allowable dwelling units. • Setbacks. This revision proposes to modify the required setbacks from dimensional front/side/rear yard setbacks to platted building envelopes. This will eliminate the potential for confusion regarding what constitutes a front, rear, or side yard. • Land Use. The applicant is proposing to allow Agriculture as a use -by -right in Zone District 2 to allow for grazing opportunities. This revision is reflected in Table 4.2 (Land Use Schedule) of the PUD Guide in Appendix S. • Affordable Housing. The affordable housing section has been removed from the PUD Guide and is now included as a separate Affordable Housing Plan in Appendix Q. • Minimum Lot Size — Zone District 1. The PUD Guide has been revised to allow a minimum lot size of 0.25 acres (instead of 0.75 acres) in Zone District 1. While no Lot in Zone District 1 is currently proposed to be less than 0.75 acres, the smaller minimum lot size would allow for the potential subdivision of the four cabins should that become desirable in the future. This revision is reflected in Section 5.11 of the PUD Guide. • Modifications. A new Section has been added to the PUD Guide to better define what constitutes both Minor and Substantial Amendments, and how such amendments are to be processed. This language is intended to provide clarity for both the County and Applicant in the consideration of potential future amendments. This has been added as Section 1.2 of the PUD Guide. McClure River Ranch 48 NARRATIVE — November 2019 5.1.4. Zone District 2 - PUD Plan Map Revisions The PUD Plan Map (Appendix R) has been revised to better represent the envisioned future design layout of Zone District 2. This includes minor changes to road alignments (less roads) and to future Building Areas. While the current Preliminary Plan application does not contemplate subdivision or development of Zone District 2, the modified PUD Plan Map better anticipates the future layout for this next phase of subdivision. 5.2. Land Use Summary The PUD Summary Table represents revisions made to Minimum Lot Size, Maximum Number of Dwelling Units per Zone District, and Maximum Overall Density per Zone as described above in Section 5.1.3. This Table may also be found in Section 2.1 of the PUD Guide in Appendix S. 5.2.1. Table 5: PUD Summary Table ITEM OVERALL ZONE DISTRICT 1 ZONE DISTRICT 2 PUD Total Acres 100.44 49.23 51.21 Minimum Open Space Percent 50 21% (of total PUD) 29% (of total PUD) Minimum Open Space Acres 50.22± 21.09± 29.13± Minimum Lot Size 0.25 acres Maximum Number of Dwelling Units 54 14 40 Maximum Dwelling Units per Lot or Tract -- 4 1 Maximum Overall Density per Zone (Not to be construed as maximum lot sizes) 1.86 AC/DU 3.52 AC/DU 1.28 AC/DU 5.3. PUD General Descriptions Article 6-302.A.1 of the Land Use and Development Code requires a written description of the proposal that addresses the following five items: 1. General project concept and purpose of the request. Response: As described in Section 5.1 above, this amendment proposes only to make certain changes to the PUD Guide and PUD Plan Map which will have negligible impacts to the overall land use and character of the community. The northern portion of the property (Zone District 1) contains primarily agricultural and equestrian -related facilities of the PUD. These facilities include barns and stables, paddocks, an exercise track for horses, two regulation -sized polo fields, ponds for the storage of McClure River Ranch 49 NARRATIVE — November 2019 irrigation water, a clubhouse, up to 14 dwelling units, and the necessary provisions of dual road access and appropriate wet and dry utilities. The southern portion of the property (Zone District 2) has a configuration that is very similar to the former PUD Plan Map. This includes roads, building areas, up to 40 residential units, and appropriate access and utility easements. The purpose of this request is to revise and replace the existing PUD Guide and PUD Plan Map. 2. Explanation of how the PUD is in general conformance with the Comprehensive Plan. Response: Section 7 of this Narrative provides demonstration of how the proposed PUD Amendment is in general conformance with the Comprehensive Plan. 3. Description of how the proposed development departs from the otherwise applicable standards of this Code but meets the intent and purpose of this Article. Response: The proposed PUD Amendment meets the intent and purpose of PUD Plan pursuant to Article 6 of the LUDC, including the provision of these PUD General Descriptions, PUD Technical Descriptions (Section 5.4), PUD Plan Map (Appendix R), and PUD Guide (Appendix S). 4. Relationship of the proposed PUD development to the existing land uses and adjacent property land uses. Response: The only requested change in land use to is allow Agriculture in Zone District 2. This would allow for grazing opportunities and is consistent with how the property has historically been used. The complete list of "Uses by Right" is included in Section 4 of the PUD Guide, Appendix 5. The subject property is currently approved for up to 54 dwelling units, and this PUD Amendment does not seek to change that. This proposed PUD amendment is highly compatible with surrounding land uses and impacts to adjacent land uses have been mitigated through appropriate PUD planning and design. Compatibility with adjacent land uses is discussed in further detail in Section 4.9.1 of this Narrative. 5. Phasing and timing for the proposed development including the start and completion date of construction of each phase. Response: Construction for the project will occur in two primary Phases, as described below: McClure River Ranch 50 NARRATIVE — November 2019 Phase 1: (2018 — 2019: NOW COMPLETE) The first Phase of construction included major improvements within Zone District 1. Work completed during this phase included all major earthwork, grading and construction of the polo fields, road (Chukka Trail), ponds, utilities, irrigation and revegetation. Phase 2: (2020) The second Phase of construction will involve the completion of all necessary infrastructure to support the build out of Zone District 1, including paving Chukka Trail, completing some minor remaining work on storm drainage facilities, installing any remaining required shallow utilities, and final landscaping within the Chukka Trail easement. Various individual building permits may also be sought during completion of the infrastructure. 5.4. PUD Technical Descriptions Article 6-302.A.2 of the Land Use and Development Code requires a written description of the proposal that addresses the following items: 1. Method and calculation used to determine overall project and specific use type densities. Response: The Comprehensive Plan designation for the property is Residential High Density, which allows a density of 1/3 acre per dwelling unit. The subject property is 100.44 acres, and thus would be allowed up to 301 dwelling units according to the Comprehensive Plan Future Land Use Map. Due to prior design objectives and natural resource protection, the property is currently zoned for up to 54 dwelling units. This application does not seek to modify to overall project density. 2. The PUD shall demonstrate how common wastewater facilities will be controlled or governed by the future owners within the PUD. Response: Zone District 1 will contain Onsite Wastewater Treatment Systems (OWTS) that will collectively serve all buildings in that District. Septic fields will be used to mitigate wastewater and will be designed in accordance with the Colorado Department of Public Health and Environment's Regulation 43 and Garfield County regulations. These wastewater systems will be collectively owned and maintained by the Association, which will be established upon filing of Final Plat for subdivision of Zone District 1. Zone District 2 will either contain a single community wastewater system, or individual OWTSs if Lot sizes are a minimum of 1 acre. Any community wastewater system will be collectively owned and maintained by the Association, which will be established upon filing of Final Plat for subdivision of the property. McClure River Ranch 51 NARRATIVE — November 2019 3. The PUD shall demonstrate how common water facilities will be controlled or governed by the future owners within the PUD. Response: The existing PUD Approval included plans for a community water system based on the production of one well (now Well No. 7). This amendment seeks to change the water supply for Zone District 1 to individual wells. Seven new wells have been permitted and installed on the property to serve the buildout of the entire PUD (see Water Rights & Supply, Appendix M). The well summary is as follows: 5.4.1.1. Table 6: Existing Domestic Water Supply Wells. Well No. Location Serves 1 Lot 1 Lot 1 2 Lot 2 Lot 2 3 Lot 3 Lot 3 4 Lot 4 Lot 4 5 Lot 5 Lot 5 6 Lot 6 Lot 6 & Maintenance Barn in Tract B 7 Lot 7 Lot 7, Cabins in Tract A & Zone District 2 (future) Each well has been tested and is adequate in both production and water quality. Pump test reports and water quality reports of each well are in the Engineering Report in Appendix H. This water system will be collectively owned and maintained by the Association, which will be established upon filing of Final Plat for Zone District 1. 4. Method of adequately providing other necessary public utilities. Response: Dry utilities for the project have been installed and are provided by various service providers, including Holy Cross Energy (electric), Black Hills (gas), and Comcast and Centurylink (communications). All necessary utilities will be located in platted Access and Utility Easements. 5. Type or method of fire protection. Response: The design team has coordinated with the Carbondale and Rural Fire Protection District regarding proper fire and life safety design for the project. The barns with included dwelling units will require sprinkler systems within the dwelling units as well as fire separation from the barns. If the clubhouse is under 5,000 square feet or 100 occupants it will not require sprinklers, but if it exceeds either it will need to be sprinkled. Required fire flows and volume will be calculated for each building and utilized to determine the final design. Dry hydrants have been installed around the site and are connected to the onsite ponds for fire suppression. McClure River Ranch 52 NARRATIVE — November 2019 6. Description of whom or what entity shall be responsible for the provision of and payment for any facilities available to the community, including but not limited to open space, common areas, and structures. Response: All common facilities will be owned and managed by Association as detailed in the Covenants, Conditions & Restrictions in Appendix P. The Association will assess membership dues to property owners within the PUD for the operation, maintenance, and upkeep of all commonly owned property. 7. Discussion of impacts on County services, schools, town services and any other unique operation that may be pertinent to a review of the proposed zone change and methods for mitigation. Response: Since this proposed amendment does not result in an increase in density or required services, there will be no additional impacts to County services, schools or towns. Based on RE -1's 2014 student generation rates, it is estimated that the project COULD generate a maximum of 41 students when using the (highest) single-family attached rate of 0.75 students per unit, and 54 total units. However, the likelihood of reaching this maximum is quite low. In accordance with Article 7-404 the Land Use and Development Code, the project will be subject to a school land dedication requirement or fee -in -lieu payment for the benefit of the RE -1 School District at the time of Final Plat. 8. Documentation showing legal access or documentation demonstrating the likelihood of achieving legal access. Response: The property currently has two legal accesses from Old Highway 82. The CDOT acceptance letters for these accesses are included in the Traffic Impact Study, Appendix L. 5.5. PUD Plan Map The PUD Plan Map identifies the Zone Districts, building envelopes, building areas, roads and easements within the McClure River Ranch PUD, and is located in Appendix R. 5.6. PUD Guide The primary purpose of the PUD Guide is to set forth a comprehensive framework of standards, restrictions and regulations which govern development and land use within the McClure River Ranch PUD. The PUD Guide will promote the orderly and compatible development of the property, while remaining somewhat flexible to allow for market changes and design innovations as the development progresses through its operational life cycle. The PUD Guide supersedes the Garfield County Land Use and Development Code (LUDC) with site specific regulations that are more McClure River Ranch 53 NARRATIVE — November 2019 appropriate to the design goals and objectives of lands contained within this PUD. The PUD Guide is located in Appendix S. 5.7. Amendment Justification Report 5.7.1. Amendment Description and Supporting Information All proposed amendments and supporting information are provided with the PUD Plan pursuant to Article 6 of the LUDC, including the provision of the PUD General Descriptions (Section 5.3), PUD Technical Descriptions (Section 5.4), PUD Plan Map (Appendix R), and PUD Guide (Appendix S). 5.7.2. LUDC Article 6-203.C. Criteria The proposed PUD amendment does not comply with the criteria for a Minor Modification, and the Director has determined that the request is a Substantial Modification. This is evidenced by the Garfield County Pre -Application Conference Summary Letter dated 3/26/19. McClure River Ranch 54 NARRATIVE — November 2019 6. Relationship to Applicable Land Use Standards 6.1. Garfield County LUDC: Article 3 — Zoning The subject property is currently zoned PUD and approved for up to 54 dwelling units, and this PUD Amendment does not seek to change that. The only requested change in land use to is allow Agriculture in Zone District 2. This would allow for grazing opportunities and is consistent with how the property has historically been used. The complete list of "Uses by Right" is included in Section 4 of the PUD Guide, Appendix S. 6.2. Garfield County LUDC: Article 7 - Standards 6.2.1. Division 1: General Standards Zone District Use Regulations The property is currently zoned PUD, and this application seeks only to amend the PUD Plan and not change the Zone District designation. Comprehensive Plan and Intergovernmental Agreements The Land Use Change demonstrates general conformance with the Garfield County Comprehensive plan as discussed in Section 7 of this Narrative. Compatibility The proposed PUD Amendment is compatible with all surrounding land uses as discussed in Section 4.9.1 of this Narrative. Source of Water The project has a legal and adequate water supply as evidenced by the Water Rights & Supply, Appendix M and Engineering Report in Appendix H. Central Water Distribution and Wastewater Systems The applicant has previously examined the potential for connection to the Mid Valley Metro District, and this was deemed infeasible. The PUD has been approved for private water and wastewater systems. If the MVMD's infrastructure or other circumstances change in the future, the property owners may re-evaluate the potential for connection. Public Utilities Adequate public utilities are provided by various service providers, including Holy Cross Energy (electric), Black Hills (gas), and Comcast and Centurylink (communications). All necessary utilities will be located in Access and Utility Easements. McClure River Ranch 55 NARRATIVE — November 2019 Access and Roadways All access roads meet or exceed minimum County standards for adequate and safe access and will support projected Average Daily Traffic (ADT) at full build out, as evidenced by the Engineering Plans in Appendix!, and the Traffic Study in Appendix L. Use of Land Subject To Natural Hazards The subject property is not located within any known natural hazard areas, as discussed in Section 4.9.4 of this Narrative. Fire Protection The subject property is located within the Carbondale & Rural Fire Protection District. The design team has consulted with the District in order to meet their requirements for fire protections, as discussed in Section 5.4 of this Narrative. 6.2.2. Division 2: Resource Protection Standards Agricultural Lands No land use changes are proposed that would adversely affect any adjacent agricultural lands. Irrigation Ditch - Zone District 1 Zone District 1 is comprised of 49.23 acres in the northern portion of the PUD. Irrigation water for Zone District 1 is served by a lateral from the Basin Ditch. The Basin Ditch is located on the north side of Highway 82, and a lateral from that ditch conveys water under the highway for the exclusive use of the subject property. This lateral has no downstream users, and therefore no impacts to other owners or users. Within the property, this lateral ditch has been improved with a flume gauge, control gates, underground piping, and storage in three lined ponds. These improvements provide for the efficient use of available water rights in irrigating lands within Zone District 1. The primary contact for the Basin Ditch is: Tim McMichael Landscape Workshop 485 County Road 112 (Mailing) 409 Delores Way (Physical) Carbondale, Colorado 81623 (970) 963-0950 (Office) Tim@landscapeworkshopinc.com McClure River Ranch 56 NARRATIVE — November 2019 Irrigation Ditches - Zone District 2 Zone District 2 is comprised of 51.21 acres in the southern portion of the PUD. No improvements are proposed for Zone District 2 as part of this application, and subdivision of this Zone will be the subject of a future Preliminary Plan application. Zone District 2 contains two irrigation ditches and associated water rights: 1) Middle Ditch, and 2) Lower Ditch. Both ditches convey water to other downstream users. The future subdivision of Zone District 2 will ensure that appropriate maintenance easements are provided, and any ditch crossings are designed so as not to alter the existing hydraulic flows. We are not aware that the Middle Ditch or Lower Ditch in Zone District 2 of the PUD are organized in any manner. Wildlife Habitat Areas The PUD allows for significant protections of wildlife habitat and provides a minimum of 50% Open Space. Wildlife impact mitigation strategies are detailed in Section 4.9.6 of this Narrative. Protection of Water Bodies The PUD provides for significant protection of water bodies, including existing wetlands and the Roaring Fork River. These protections are discussed in detail in Sections 4.9.2 and 4.9.5 of this Narrative. Drainage and Erosion Drainage and erosion control of the site is discussed in detail in Section 4.9.5 of this Narrative and detailed in the Engineering Plans in Appendix I. Environmental Quality Air quality will be monitored and controlled by mitigation measures discussed in Section 4.9.7 of this Narrative. Water quality will be monitored and controlled by mitigation measures discussed in Section 4.9.5 of this Narrative. Wildfire Hazards The subject property is not rated (NR) on the Garfield County Wildland Fire Susceptibility Index Map. The property will continue to be well -irrigated and contains primarily low-lying riparian vegetation along the Roaring Fork River corridor. Similar properties in Garfield County have a Low Wildland Fire Susceptibility Index. Natural and Geologic Hazards The subject property is not located within any known natural hazard areas, as discussed in Section 4.9.4 of this Narrative. Reclamation Any disturbed areas of the site will be appropriately reclaimed as detailed in the Engineering Report (Appendix H) and the Engineering Plans (Appendix I). McClure River Ranch 57 NARRATIVE — November 2019 6.2.3. Division 3: Site Planning Compatible Design The site design is compatible with the existing character of adjacent uses, including site organization, operational characteristics, buffering, and material usage. Off -Street Parking and Loading Standards The PUD provides adequate parking and loading, including allowances for off-street parking lots and setbacks that will allow adequate driveway parking. These standards are detailed in the PUD Guide, Appendix S. Landscaping Standards The Landscape Plans (Appendix J) demonstrate conformance with Landscaping Standards per the PUD Guide in Appendix S. Lighting Standards While community lighting has not yet been proposed for this project, any lighting will comply with the Exterior Lighting Standards per the PUD Guide in Appendix S. Snow Storage Standards Adequate snow storage will be provided as discussed in the Engineering Report, Appendix H. Trail and Walkway Standards Trail and walkway designs will conform to Landscaping Standards per the PUD Guide in Appendix S. McClure River Ranch 58 NARRATIVE — November 2019 6.2.4. Division 4: Subdivision Standards & Design Specifications General Subdivision Standards All common facilities will be owned and maintained by the Association, as detailed in the Covenants, Conditions & Restrictions in Appendix P. Domestic animal control is described in detail in Section 4.9.6 of this Narrative, and such protections will be recorded in the final CCRs at the time of Final Plat. Any new solid wood burning stove will be limited to one per Lot and will be memorialized in the final CCRs. Development in the floodplain is only allowed by the approved Floodplain Development Permit (FDPA6264), conformance to which will be demonstrated at the time of subdivision for Zone District 2. Subdivision Lots The proposed lot layout complies with County standards for a PUD as indicated on the Preliminary Plan in Appendix N. Survey Monuments Upon approval and recording of Final Plat, all survey monumentation will conform to the standards of Land Use and Development Code Article 7-403. School Land Dedication In accordance with Article 7-404 of the Land Use and Development Code, the project will be subject to a school land dedication requirement or fee -in -lieu payment for the benefit of the RE -1 School District at the time of Final Plat. The applicant intends to process a fee -in -lieu payment at the time of Final Plat. McClure River Ranch 59 NARRATIVE — November 2019 Road Impact Fees In accordance with Article 7-405 of the Land Use and Development Code, the County will collect Road Impact Fees at the time of building permit applications. The Road Impact Fees for the full build -out of the project have been estimated using the current County fee table as follows: 6.2.4.1. Table 7: Road Impact Fee Estimate.

Relationship to Garfield County Comprehensive Plan The Garfield County Comprehensive Plan includes general goals and policies that apply to all areas of the County. Certain goals and policies that relate specifically to McClure River Ranch are addressed in this section. Selections from the Comprehensive Plan are displayed in bold text; and Applicant discussions and responses are displayed in regular text. 7.1. Future Land Use Future Land Use Map (Revision 13: 12-18-13) The Future Land Use Map (FLUM) for the subject property has a designation of Residential High (RH) with a density range of 1/3 to <2 Ac/Du. This designation allows a range from 50 to 301 dwelling units for the 100.44 acre property. The PUD is approved for a maximum of 54 dwelling units, and therefore is consistent with the Residential High designation, albeit at the low end of the allowed range. The description for the Residential High (RH) future land use designation includes the following: "Criteria for determining RH density within the allowed range will be specifically determined by the Planning Commission and will be based on "degree of public benefit", considering factors such as: amount of affordable housing including a mix of housing types, amount of parks/trails/ open space, energy conservation, fiscal impacts on the County, preservation of views, providing for schools and other public needs, etc. The PUD will provide Affordable Housing Mitigation equal to 10% of the total built dwelling units, a mix of allowed housing types, preservation of views from the Hwy 82 corridor, and a minimum Open Space amount of 50% (50.22 acres). The Comprehensive Plan prescribes Planned Unit Development (PUD) as one of the compatible Zone Districts for the Residential High designation. The property is currently zoned PUD, and this proposal does not propose a change in Zone District. 7.2. Urban Growth Areas and Intergovernmental Coordination Through the use of Urban Growth Areas (UGA), the Comprehensive Plan encourages development within UGAs to be consistent with municipal land use plans and policies, and where public services and infrastructure can be provided in an efficient and cost-effective manner. "Encourage future development requiring urban services to be located in areas where these services are or can readily be made available." McClure River Ranch 61 NARRATIVE — November 2019 The subject property is not located within the Carbondale UGA, or the 3 -mile Area of Influence. The proposed project does not require urban services such as municipal water and sewer. 7.3. Housing The housing goals and policies of the Comprehensive Plan generally apply to new residential development. "Garfield County is committed to take appropriate, cost-effective measures to assure that new development contributes its fair share to providing housing affordable to those that live and work in the county." The County has an inclusionary housing requirement for new residential developments only in the Roaring Fork Valley portion of the County (where housing costs are generally higher than other areas of the County). The PUD is located in Comprehensive Plan Study Area 1 and will provide affordable housing mitigation in an amount equal to ten percent (10%) of the total dwelling units within the PUD. The maximum number of allowed dwelling units within the PUD is fifty-four (54), therefore, the PUD will provide up to five (5) Affordable Housing Units per the Affordable Housing Plan in Appendix Q. 7.4. Transportation Of great importance in the Comprehensive Plan is the ability of the County to maintain its road system. Two primary issues with County Roads are generally related to commuter traffic stressing the carrying capacity of County roads, and heavy truck traffic from industrial operations impacting the integrity of County roads. "Ensure that county roads are constructed and maintained on a safe, and fiscally sustainable basis." The Traffic Study (Appendix 1) provides significant detail on projected traffic generation from the project. The proposed project does not directly access any County road, but rather is accessed by the CDOT-administered Old Highway 82 frontage road. The Traffic Study does not identify any additional improvements to Old Highway 82 that would be necessitated by this project. 7.5. Economics, Employment and Tourism The construction industry is an important economic sector for Garfield County, comprising 17% of the employment base, while the tourism sector makes up another 10% of the employment base. The Comprehensive Plan recognizes the importance of maintaining a diverse economic base. McClure River Ranch 62 NARRATIVE — November 2019 "Where appropriate, encourage diverse tourism related development in order to sustain it as an economic and employment base in Garfield County. In the near-term, the project will generate significant opportunities for the local construction industry. These opportunities will continue with the second phase of infrastructure improvements and continue through the construction of the final dwelling. The project will also create long-term local opportunities for design, legal, property management, real estate and other professionals. Supplementing the economic benefit of construction will be that of the tourism industry (specifically agri-tourism), in which people will visit the horse facilities for various special events, tours, and matches. The project has already demonstrated the ability to draw national and international guests, who also patronize other businesses in Garfield County. 7.6. Recreation, Open Space and Trails The Comprehensive Plan recognizes the value of open lands, recreational opportunities, parks, trails and rivers. Access to these amenities contributes to quality of life, and is important to County residents and the tourism sector of the local economy. "Assure that new residential development provides recreation opportunities for county residents that are appropriate to the density and type of development or that contribute land and/or funding to a county -wide trail and recreation system." The PUD includes the provision of internal recreational opportunities; including open space and trails. A minimum of 50% of the PUD will be maintained as Open Space and includes a corridor along the Roaring Fork River which will preserve the public river experience for floaters, fishermen, and bicyclists on the Rio Grande Trail. 7.7. Agriculture Through the Comprehensive Plan, the County values the preservation of agricultural lands, rural character, and agricultural heritage. "Promote the continuation and expansion of agricultural uses." "Preserve a significant rural character in the county." "Preserve scenic and visual corridors in the county." The project includes the development of significant agricultural land uses, including a horse breeding and training center with customary agricultural structures and fields. The project also includes the preservation of the McClure cabin, which was occupied by Thomas McClure — one of the first successful potato farmers in eastern Garfield County in the late 1800's. The cabin has been McClure River Ranch 63 NARRATIVE — November 2019 relocated and restored to preserve an important piece of history for the property. The visual corridor from Highway 82 will be preserved in an agricultural context. This northern portion of the property will include three new barns and polo fields that will maintain significant areas of open lands. This application includes 3D computer renderings (Appendix 0) of the proposed improvements from two northerly oblique perspectives, looking southeast and southwest. These views were selected for reviewers to gain a comprehensive understanding of overall improvements, since much of the proposed development will not be highly visible from Highway 82. Additional photographs from the Highway 82 corridor are also included in Appendix 0, including locations of potential visual impacts. The majority of lands adjacent to the CDOT right-of-way will be maintained as open land. This is also true for lands adjacent to the Waldorf School on the east, and Blue Creek Ranch on the west. Along the Highway 82 right-of-way are three proposed building envelopes for barns, with a maximum height of 28'. These three building envelopes comprise 619' of the 2125' property boundary, which equals 29% of that boundary that could be visually impacted. The balance of 71% of this boundary is to remain visually unimpeded for a minimum distance of 215' into the property (and in most cases hundreds of feet further), thereby protecting the vast majority of the existing viewshed as seen from Highway 82. Concerning the potential for ridgeline visual impacts, the site is generally level with an overall east - west gradient of 0.8%, and an overall north -south gradient of 1.0%. The property generally drains from northeast to southwest at an overall grade of 1.4%, changing in elevation approximately 43 vertical feet over a distance of 3070 feet. There are no ridgelines within the property and therefore no such visual impacts. 7.8. Water and Sewer Services Through the Comprehensive Plan, the County values the preservation and enhancement of high quality water resources and proper waste water treatment. "Ensure the provision of legal, adequate, dependable, cost-effective and environmentally sound sewer and water services for new development." The project will utilize existing wells to support Zone District 1, and a Central Water Distribution System to support Zone District 2. The property has significant raw water rights from several ditches, including the Basin Ditch, Middle Ditch, and Lower Ditch. These water rights will be maintained and utilized to provide irrigation support for the property. The project will utilize Onsite Wastewater Treatment Systems (OWTS), which will be designed in accordance with the Colorado Department of Public Health and Environment's Regulation 43 and Garfield County regulations. McClure River Ranch 64 NARRATIVE — November 2019 7.9. Natural Resources The Comprehensive Plan promotes the preservation and enhancement of wildlife habitat, native vegetation, riparian corridors, scenic resources, the night sky, and air and water quality. These natural resources contribute significant value to the tourism sector of the local economy. "Ensure that natural, scenic, ecological, and critical wildlife habitat resources are protected and/or impacts mitigated." "Preserve natural drainage patterns so the cumulative impact of public and private land use activities will not cause storm drainage and floodwater patterns to exceed the capacity of natural or constructed drainage ways, or to subject other areas to an increased potential for damage due to flooding, erosion or sedimentation or result in pollution to streams, rivers or other natural bodies of water." The Roaring Fork River corridor is an important natural environment on the south side of the subject property. Within this area are floodplains, wetlands, and mixed forests which create wildlife habitat and serve important ecological functions. These areas will largely be preserved as Open Space within the PUD. The drainage plan has been designed to allow for proper infiltration and groundwater recharge. Inlet structures, piping, swales, infiltration depressions and overflow structures will convey runoff through the site. Proposed roads will drain into grass -lined swales and will convey runoff to localized depressions via storm inlets and piping when necessary. Localized depressions will be the main form of retention to provide water quality and promote infiltration, while larger depressions will be used for retention. Drainage and erosion control of the site during construction activities will be managed under the authority of a Colorado Department of Public Health & Environment (CDPHE) discharge permit and associated Stormwater Management Plan. 7.10. Mineral Extraction Garfield County contains significant mineral resources. Through the Comprehensive Plan, the County recognizes the value of the resource extraction industry in contributing to a diverse and stable economy. The Plan also promotes fair mitigation of any negative impacts extraction activities may cause. "Ensure that mineral extraction is regulated appropriately to promote responsible development and provide benefit to the general public." "Ensure that mineral extraction activities mitigate their effects on the natural environment, including air quality, water quality, wildlife habitat or important visual resources." "In working with mineral extraction projects, the county will protect the public health, safety and welfare of its citizens." McClure River Ranch 65 NARRATIVE — November 2019 This PUD does not allow any mineral extraction activities, and therefore it is not possible to apply or compare the County's Mineral Extraction goals and policies to this project. 7.11. Renewable Energy The Comprehensive Plan promotes the development of renewable energy sources in appropriate locations throughout the County, and the County has ensured that regulations for such land uses are not overly burdensome. The Comprehensive Plan also acknowledges the potential of alternative energy production for further economic diversification. "Promote and encourage the development of renewable energy resources within the county." This PUD has specific allowances for renewable energy production at an appropriate neighborhood scale. The PUD Guide (Appendix S) allows for the use of both Accessory and Small Solar Energy Systems. Accessory Solar Energy Systems are those rated less than 15 kilowatts and are allowed in both Zone District 1 and 2 of the PUD. Small Solar Energy Systems are those rated 15 to 500 kilowatts and are allowed in Zone District 1 of the PUD. McClure River Ranch 66 NARRATIVE — November 2019
