Impact Analysis Where the proposed development will impact specific features of the site, the Applicant shall describe both the existing conditions and the potential changes created by the project. The Impact Analysis shall include a complete description of how the Applicant will ensure that impacts will be mitigated and standards will be satisfied. The following information shall be included in the Impact Analysis. 1. Adjacent Land Use. Existing use of adjacent property and neighboring properties within 1,500-foot radius. Existing use of adjacent property and neighboring properties within a 1,500-ft. radius is primarily Rural residential and Bureau of land management. See map and GIS representations below. 2. Site Features. A description of site features such as streams, areas subject to flooding, lakes, high ground water areas, topography, vegetative cover, climatology, and other features that may aid in the evaluation of the proposed development. The closest water body is West Coulter Creek which lies 500 ft east of the project site. Flooding is not a major concern. Climatology is semi-arid, and the primary vegetation of the area includes grasses, scrub oak, juniper, and sage. According to FEMA flood panel 0802051500B there is no high risk of flooding in this area. It is outside of any flood zone. FEMA flood zone map attached below. The landscape position for the solar field is considered summit and will not be impacted by stormwater drainage. The slope shape is convex – convex (VV) towards the southwest. Existing topography in the vicinity of the solar array slopes from northeast towards the southwest at grades of between 1.0 to 31.0 percent. Grades are not proposed to change under proposed conditions. 3. Soil Characteristics. A description of soil characteristics of the site that have a significant influence on the proposed use of land. According to the Web Soil Survey for the Natural Resources Conservation Service (NRCS), soils associated with this subject property are classified as map units 59-Iyers loam and 67 Jerry-Millerlake loams. Iyers has grades of between 6 to 25 percent, which does agree with field observation. Jerry-Millerlake has grades between 25 to 45 percent, which also agrees with field observations. Soil composition can be seen in the Web Soil Survey information below 4. Geology and Hazard. A description of geologic characteristics of the area including any potential natural or manmade hazards and a determination of what effect such factors would have on the proposed use of the land. Approximately 300 million years ago, a pair of mountain ranges collectively named the Ancestral Rockies formed on either side of the Roaring Fork Valley. Once the ancestral sea dried up, it left a thick layer called the Eagle Valley Evaporite. The pale gypsum visible throughout the area is most apparent near the town that takes its name. In addition to this, sandstone, conglomerates, and shales were deposited by streams and rivers coming off of these ancient peaks. On this side of the Rockies this is known as the Maroon Formation. There are no geologic characteristics in the proposed area, including any potential natural or manmade hazards, that would significantly affect or impact the proposed solar PV array. 5. Groundwater and Aquifer Recharge Areas. Evaluation of the relationship of the subject parcel to Floodplains, the nature of soils and subsoils and their ability to adequately support waste disposal, the Slope of the land, the effect of sewage effluents, and the pollution of surface Runoff, stream flow, and groundwater. The elevation of the proposed solar PV system is approximately 6,884 ft. above sea level, almost 500 ft. above the Roaring Fork River Valley below; additionally, the project site slopes downhill toward the aforementioned Roaring Fork River Valley. The proposed site is not located in a flood plain. The nature of the soils and subsoils and their ability to adequately support waste disposal is not applicable to the project; all project-related wastes will be disposed of within 10 days of project completion, and there will be no wastewater or sewage effluents generated by or associated with the project. Likewise, there will be no appreciable pollution generated during system installation or during subsequent operation that would have the potential to pollute surface runoff, stream flow, or groundwater. 6. Environmental Impacts. Determination of the existing environmental conditions on the parcel to be developed and the effects of development on those conditions, including: a. Determination of the long-term and short-term effect on flora and fauna; The project will have no detrimental effects on flora or fauna during either installation or subsequent operation. Natural grass seed will be applied to cover any disturbed dirt from the installation process. b. Determination of the effect on designated environmental resources, including critical wildlife habitat; The project will have no detrimental effects on any designated environmental resources, including critical wildlife habitat. While there are elk, deer and other large mammals present on the property, the proposed solar field takes up a very small portion of the property allowing for normal wildlife migrations. The majority of the property remains natural and untouched. c. Impacts on wildlife and domestic animals through creation of hazardous attractions, alteration of existing native vegetation, blockade of migration routes, use patterns, or other disruptions; The proposed project should attract neither wildlife nor domestic creatures; in the event that any beasts should be attracted, ¼ in. hardware cloth/protective grating shall cover the rear of the ground-mounted array, not allowing access to wires or electrical components. From the arrays to the point of interconnection (POI), conductors shall be underground and conduit-protected, and at the equipment mast near the utility mast (POI), conduit and/or electro-metallic tubing (EMT) shall cover any conductors, not allowing access. To the best of our knowledge, the ground-mounted solar PV arrays should not affect, block, or disrupt any migration routes or use patterns, nor cause any other appreciable disruptions. While there are elk, deer and other large mammals present on the property the proposed solar field takes up a very small portion of the property allowing for normal wildlife migrations. The majority of the property remains natural and untouched. d. Evaluation of any potential radiation hazard that may have been identified by the State or County Health Departments. To the best of our knowledge, there is no known potential radiation hazard at the project location that has been identified by any health departments. The solar PV arrays themselves have no radioactive characteristics. 7. Nuisance. Impacts on adjacent land from generation of vapor, dust, smoke, noise, glare or vibration, or other emanations. The solar PV arrays shall generate no appreciable amounts of vapor, dust, smoke, noise, glare or vibration, or any other notable emanations that would impact adjacent land. The nearest adjacent land to the project site will be thousands of feet away. 8. Hours of Operation. The Applicant shall submit information on the hours operation of the proposed use. The solar PV shall generate power during times between sunrise and sunset. There is no associated noise or moving parts.  $UWLFOH6WDQGDUGV&RPSOLDQFH Article 7: Standards Division 1. General Approval Standards 7-101. Zone District Use Regulations The Land Use Change shall comply with Article 3, Zoning, including any applicable zone district use restrictions and regulations. The site in question- 1708 County Road 121, Carbondale (unincorporated Garfield County), CO 81623- is classified as Rural (R) zoning, as defined in Garfield County Article 3: Zoning, Division 1. General Provisions, 3- 101: Establishment of Zone Districts. The definition of Rural zoning classification includes the following: Uses, densities, and standards established for this zone district are intended to protect the existing character of the area from uncontrolled and unmitigated residential, commercial, and industrial use. The zone district provides for the use of natural resources, recreational development, rural residential, and other uses. The addition of the proposed ground-mount solar photovoltaic (PV) system shall be controlled, and by no means unmitigated. The use of the “natural resource” of the sun, as well as a rural residential classification are both consistent with the permitted Rural zoning classification uses as defined above. Existing land uses, as well as the proposed solar PV array, both comply with the lot size, set-back, and height standards as given in Table 3-201: Zone District Dimensions. The project will not conflict with any County frontage requirements as defined in 3-202. General Restrictions and Measurements. The project does not conflict with any provisions as set forth in the following sections: •3-301: Floodplain Overlay Regulations •3-302: Drinking Water Constraints Overlay Regulations •3-303: Airport/Heliport Influence Area Overlay Regulations As classified under Table 3-403: Use Table, the lot’s principal Use Category is Household Living, and the primary Use Type is Dwelling, Single-Unit (Residential Use). The proposed solar PV system addition falls under Use Type Solar Energy System, Small (Rural (R) Residential District). Under Garfield County’s classification system, this is listed as “A,” or as requiring an Administrative Review. 7-102. Comprehensive Plan and Intergovernmental Agreements The Land Use Change is in general conformance with the Garfield County Comprehensive Plan and complies with any applicable intergovernmental agreement. The Land Use Change is in general conformance with the Garfield County Comprehensive Plan and complies with any applicable intergovernmental agreement. 7-103. Compatibility The nature, scale, and intensity of the proposed use are compatible with adjacent land uses. The nature and scale of the proposed use are installation of a 62 module, 24.8 kW ground-mounted solar PV array in the southwestern portion of the property, approximately 300 ft. north from the existing home, where grid interconnection will be achieved. There will be 2 rows, each 31 modules (approximately 49 ft.) wide. The combined footprints of the arrays will be approximately 2085 sq ft., or 0.004997% of the parcel’s 960 acre size. At the proposed tilt angle of 30 degrees. Solar arrays are quite common on rural residential properties. A modestly sized residential array, the proposed array would eliminate the equivalent of approximately 28,460 lb. of carbon dioxide annually. Having been around for several decades commercially, solar PV is an attractive, environmentally beneficial, and commonly accepted part of the modern landscape, both on the residential, as well as commercial, levels. The shortest distance the project parcel is from the nearest public roadway, County Road 121, is approximately 1,700ft. Trees and vegetation to the north, south, and east would obscure the views of the proposed array from the existing neighboring residences. Notice of the proposed array installation shall be sent to the owners of neighboring parcels as well, making them aware of it as well as allowing for comments. There are no planned landscape modifications, and drainage patterns will not be modified. 7-104.

"Green" glare is glare with low potential to cause an after-image (flash blindness) when observed prior to a typical blink response time. "Yellow" glare is glare with potential to cause an after-image (flash blindness) when observed prior to a typical blink response time. Times associated with glare are denoted in Standard time. For Daylight Savings, add one hour. The algorithm does not rigorously represent the detailed geometry of a system; detailed features such as gaps between modules, variable height of the PV array, and support structures may impact actual glare results. However, we have validated our models against several systems, including a PV array causing glare to the air-traffic control tower at Manchester-Boston Regional Airport and several sites in Albuquerque, and the tool accurately predicted the occurrence and intensity of glare at different times and days of the year. Several V1 calculations utilize the PV array centroid, rather than the actual glare spot location, due to algorithm limitations. This may affect results for large PV footprints. Additional analyses of array sub-sections can provide additional information on expected glare. This primarily affects V1 analyses of path receptors. Random number computations are utilized by various steps of the annual hazard analysis algorithm. Predicted minutes of glare can vary between runs as a result. This limitation primarily affects analyses of Observation Point receptors, including ATCTs. Note that the SGHAT/ ForgeSolar methodology has always relied on an analytical, qualitative approach to accurately determine the overall hazard (i.e. green vs. yellow) of expected glare on an annual basis. The analysis does not automatically consider obstacles (either man-made or natural) between the observation points and the prescribed solar installation that may obstruct observed glare, such as trees, hills, buildings, etc. The subtended source angle (glare spot size) is constrained by the PV array footprint size. Partitioning large arrays into smaller sections will reduce the maximum potential subtended angle, potentially impacting results if actual glare spots are larger than the sub-array size. Additional analyses of the combined area of adjacent sub-arrays can provide more information on potential glare hazards. (See previous point on related limitations.) The variable direct normal irradiance (DNI) feature (if selected) scales the user-prescribed peak DNI using a typical clear-day irradiance profile. This profile has a lower DNI in the mornings and evenings and a maximum at solar noon. The scaling uses a clear-day irradiance profile based on a normalized time relative to sunrise, solar noon, and sunset, which are prescribed by a sun-position algorithm and the latitude and longitude obtained from Google maps. The actual DNI on any given day can be affected by cloud cover, atmospheric attenuation, and other environmental factors. The ocular hazard predicted by the tool depends on a number of environmental, optical, and human factors, which can be uncertain. We provide input fields and typical ranges of values for these factors so that the user can vary these parameters to see if they have an impact on the results. The speed of SGHAT allows expedited sensitivity and parametric analyses. The system output calculation is a DNI-based approximation that assumes clear, sunny skies year-round. It should not be used in place of more rigorous modeling methods. Hazard zone boundaries shown in the Glare Hazard plot are an approximation and visual aid based on aggregated research data. Actual ocular impact outcomes encompass a continuous, not discrete, spectrum. Glare locations displayed on receptor plots are approximate. Actual glare-spot locations may differ.
