Describe the surrounding land uses of the site and how the proposed use is compatible with them. Response: To the north of the subject property, there is a 21.5 -acre oil/gas facility owned by Duke Energy Field Services, LP. The balance of the land to the north is 119.88 -acre parcel owned by Kerr-McGee Oil & Gas Onshore, LP which is vacant ground, except for three (3) oil/gas facilities. To the east of the subject property, there is a 557.69 -acre parcel that is owned by the State of Colorado. This parcel has multiple oil/gas facilities, an existing 2 MW community solar facility, and the balance on the land appears to be for agricultural uses. To the south of the subject property, there is a 161.41 -acre parcel that has an existing farmhouse and agricultural uses. There are also several oil/gas facilities on the property. To the west of the subject property there is a 75.81 -acre parcel that has an existing farmhouse and agricultural uses. The proposed community solar facility is very compatible with the surrounding uses. The proposed use has no odors or noise, and once the construction phase is completed, there will be very limited traffic associated with the use. The panels are coated with an anti -reflective technology to enhance their ability to capture sunlight, while minimizing reflective glare. The site will not require grading which will help minimize any negative drainage impacts to surrounding properties. Any areas that are disturbed during the construction phase will be re- seeded with native grasses and wildflowers. The existing farmhouse west of the proposed facility will be screened by the installation of Rocky Mountain Junipers, planted on the western edge of the subject property. Once the useful life of the facility is reached, the panels, racking, cables, and other equipment will be removed and the site returned to the condition it was in prior to the solar facility being built. 6. Describe the hours and days of operation (e.g. Monday thru Friday 8:00 a.m. to 5:00 p.m.). Response: Solar facilities are unmanned facilities that operate 24-7, but only produce power during the daylight hours. During the equipment delivery/construction phase, there will be a construction crew of approximately 20 full-time workers on the site. The site will be occupied Monday through Saturday, 8:00 A.M. to 5:00 P.M. during the construction phase. The 4.75 MW (AC), 4.99 MW (DC) facility will take approximately one -hundred nine (109) days to construct and interconnect. Once the construction phase is completed, the site will be visited quarterly for routine maintenance and as needed for emergency maintenance. In addition, mowing and 2 I SunShare COMMUNITY SOLAR 1724 Gilpin Street, Denver, CO 80218 • info@mysunshare.com • 800.793.0786 • MYSUNSHARE.COM noxious weed control crews will also be on the site as needed. There will be no exterior lighting associated with the proposed facility. 7. Describe the number of employees including full-time, part-time, and contractors. If shift work is proposed, detail number of employees, schedule and duration of shifts. Response: During the equipment delivery/construction phase, there will be approximately 20 full-time workers on the site. After construction, a one or two person crew will visit the site quarterly for routine maintenance and as needed for corrective maintenance. There is no shift work being proposed. 8. Describe the maximum number of users, patrons, members, buyers or other visitors that the site will accommodate at any one time. Response: During the delivery/construction phase, approximately 20 people will be on site. In addition, there will be approximately 8-10 delivery trucks that will deliver equipment to the site during the equipment/construction phase. After construction, the site will be an unmanned facility. 9. List the types and maximum number of animals to be on the site at any one time (for dairies, livestock confinement operations, kennels, etc.). Response: There will be no animals on the site once the proposed solar use is commenced. 10. List the types and number of operating and processing equipment. Response: There will be a total of 12,012 400W Monocrystalline modules at this proposed facility. 11. List the types, number and uses of the existing and proposed structures. Response: There are no existing structures on the subject property. There will be no structures associated with the proposed solar facility. 12. Describe the size of stockpile, storage or waste areas. Response: There will be no storage or stockpiling of wastes, chemicals, and/or petroleum on the site. Any fuel needed for equipment during the construction phase will be brought to the site on portable fuel trucks. During the construction phase, there will be a temporary materials and equipment laydown yard/parking for the construction phase only, located on the interior of the facility. This laydown/parking area will be approximately 50' X 250' in size and will be removed after the construction phase is completed. 3 lAtk • SunShare COMMUNITY SOLAR 1724 Gilpin Street, Denver, CO 80218 • info@mysunshare.com • 800.793.0786 • MYSUNSHARE.COM 13. Describe the method and time schedule of removal or disposal of debris, junk and other wastes associated with the proposed use. Response: During the construction phase, waste will be stored in refuge dumpsters, which will be emptied on a regular basis or as needed. Once the facility is operational, there will be no waste or refuge produced from the solar operation. Any waste or trash created while maintaining the facility will be removed from the site at the time the maintenance is performed. 14. Include a time -table showing the periods of time required for the construction of the operation. Response: The following is a schedule of time required for each phase of the construction operation: ■ Solar Facility Components First Deliver ■ Perimeter Fence Installation ■ Solar Panel Foundation Installation ■ Racking, Trenching, Wiring ■ Solar Panel Installation ■ Inspection & Set Meters ■ System Testing & Commissioning Day 1 Day 1 to Day 11 Day 1 to Day 30 Day 30 to Day 64 Day 64 to Day 94 Day 94 to Day 99 Day 99 to Day 109 15. Describe the proposed and existing lot surface type and the square footage of each type (i.e. asphalt, gravel, landscaping, dirt, grass, buildings). Response: The subject property is currently being farmed and will need to be re -seeded within the construction area. Following the completion of the construction for each phase, disturbed areas within the limits of construction, such as roadcuts, utility trenches, and other areas where vegetation has been removed, altered, or eliminated, will be reseeded with native grass seed and wildflower mix. There will be approximately 29,000 square feet of gravel access drive, including the hammerhead turn -around at the southern end of the access drive. In addition, there will be a gravel laydown area that is approximately 12,500 square feet, for a total of 41, 500 square feet of gravel surface area. There will be two (2) concrete transformer pads, each measuring approximately 48 square feet, for a total of 96 square feet of concrete area. Landscaping will be installed along the western border of the subject property. The actual square footage of landscaping will be determined during the USR application process. There are no existing buildings on the subject property and no new buildings are being proposed for the intended use. 16. How many parking spaces are proposed? How many handicap -accessible parking spaces are proposed? 4 TAV 4,1 '1SunShare COMMUNITY SOLAR 1724 Gilpin Street, Denver, CO 80218 • info@mysunshare.com • 800.793.0786 • MYSUNSHARE.COM Response: There will be two (2) internal parking spaces for vehicles servicing the facility. There will be no handicap -accessible parking spaces provided, as this is not a facility for general public use. 17. Describe the existing and proposed fencing and screening for the site including all parking and outdoor storage areas. Response: The two (2) internal parking spaces will be screened by the solar array. There will be no outdoor storage associated with this proposed solar facility. To comply with the National Electric Code, there will be an 8' tall game fence installed around the entire perimeter of the site. The fence and gate will be constructed of 4" X 4" welded rod material with a barbless wire apron extended out at a 45 -degree angle for the top 1' of fencing. The fence will be painted with a color to blend with the existing site conditions. 18. Describe the existing and proposed landscaping for the site. Response: The entire parcel has been used for agricultural purposes and is a dirt surface. Once the construction phase is completed, the area within the solar facility fence will be seeded with a native grasses and wildflower mixture. As previously mentioned, the closest residence to the proposed facility is a farmhouse located adjacent to the northwest corner of the subject property. To help minimize the visual impact to this residence, SunShare, LLC will install screening along the western border of the subject property, in the vicinity of the residence. This screening will consist of a game fence and planting Rocky Mountain Junipers, that will provide year-round screening of the proposed facility. SunShare, LLC will coordinate a water supply for the newly planted trees with the current tenant farmer. A watering schedule will be prepared to help ensure the trees survive and are maintained during the entire operation phase of the facility. 19. Describe reclamation procedures to be employed as stages of the operation are phased out or upon cessation of the Use by Special Review activity. Response: The subject property is currently being farmed and will need to be re -seeded within the construction area. Following the completion of the construction for each phase, disturbed areas within the limits of construction, such as roadcuts, utility trenches, and other areas where vegetation has been removed, altered, or eliminated, will be reseeded with native grass seed and wildflower mix. Once the useful life of the facility is realized, the panels, racking, cables, and other equipment will be removed and the site returned to the condition it was in prior to the solar facility being built. 20. Describe the proposed fire protection measures. 5 • SunShare COMMUNITY SOLAR 1724 Gilpin Street. Denver, CO 80218 • info@mysunshare.com • 800.793.0786 • MYSUNSHARE.COM Response: The subject property is within the Platteville-Gilcrest Fire District service area. Fire access within the facility will be via a 20' -wide gravel driveway, with a hammerhead turn- around at the end of the drive. Grasses within the solar facility will be mowed as needed, to help prevent the spread of range fires. 21. Explain how this proposal is consistent with the Weld County Comprehensive Plan per Chapter 22 of the Weld County Code. Response: The Weld County Comprehensive Plan (Weld County Code, Chapter 22), addresses "Alternative Energy Resources — Goals and Policies". The proposed use of the subject property as a solar power generation facility is consistent with the goals and policies of this section. Alternative Energy Goal No. 1 is to "Support and encourage research, development and use of alternative energy sources". This proposed use is for the development and use of alternative energy sources by the citizens and business of Weld County. This facility will provide a clean, renewable energy source for citizens and businesses who are served by Xcel Energy. Alternative Energy Policy 1.5. Calls for supporting and developing the use of solar energy. This proposed use is in keeping with this policy. Recommended Strategy AE.1.5.b. proposes "Creating incentives that encourage large-scale commercial solar collections". The proposed project, would be considered a Medium -Scale Solar. Weld County recently reviewed its regulations regarding solar power generation facilities. Strategy AE.1.6.a. of Chapter 22 addresses this and recommends reviewing County regulations to ensure support of all alternative energy resources for small and large-scale applications. 22. Explain how this proposal is consistent with the intent of the zone district in which it is located. (Intent statements can be found at the beginning of each zone district section in Article III of Chapter 23 of the Weld County Code.) Sec. 23-3-10. - Intent. "Agriculture in the COUNTY is considered a valuable resource which must be protected from adverse impacts resulting from uncontrolled and undirected business. industrial and residential land USES. The A (Agricultural) Zone District is established to maintain and promote agriculture as an essential feature of the COUNTY. The A (Agricultural) Zone District is intended to provide areas for the conduct of agricultural activities and activities related to agriculture and agricultural production. and for areas for natural resource extraction and energy development, without the interference of other. incompatible land USES." Response: The subject property is zoned Agricultural (A) and is within a "Non -Urbanizing Drainage Area". Medium -Scale Solar Facilities are permitted as a Use by Special Review in the Agricultural zone district. The Use by Special Review process allows for adequate review by the Planning staff, Planning Commission, and the Board of County Commissioners, to ensure 6 )1J ki • SunShare COMMUNITY SOLAR 1724 Gilpin Street, Denver, CO 80218 • info@mysunshare.com • 800.793.0786 • MYSUNSHARE.COM compatibility with surrounding land uses. Additionally, citizens are afforded adequate opportunities to express their concerns in the public hearing setting before any solar facility can be constructed on agriculturally- zoned land. Within the stated intent of the "Agricultural" Zone District is the specific reference to "natural resource extraction" and "energy development". This proposed solar power generation plant is totally in compliance with the intent of the "Agricultural" Zone District. Solar facilities allow farmers and ranchers another use for their land and a viable stream of income beyond traditional farming and ranching uses. 23. Explain how this proposal will be compatible with future development of the surrounding area or adopted master plans of affected municipalities. Response: The subject property is just outside the Platteville Urban Growth Area. The Town of Gilcrest is to the north, but the subject property is not within the town's urban growth area. The comprehensive plans for Platteville and Gilcrest are both silent on renewable energy development, however they do encourage the development of oil/gas energy as part of their e conomic future. Weld County provided two (2) Notices of Inquiry for the Towns of Platteville and Milliken. The Town of Platteville has responded and is not interested in pursuing annexation at this time. The Town of Milliken has responded directly to the Weld County Planning staff. The proposed solar facility will be compatible with future development of the surrounding area. Much of the surrounding area is now and will probably remain agricultural in nature for the foreseeable future. In addition, oil/gas production will likely continue in the immediate area. Solar development is very compatible with farming and ranching uses and oil/gas development. Renewable projects provide farmers and ranchers a viable alternate use to traditional farming and ranching uses on their land. Since there are no permanent structures being built as part of this proposal, the land will be returned to its agricultural use once the e conomic viability of the solar facility has ended. 24. Explain how this proposal impacts the protection of the health, safety and welfare of the inhabitants of the neighborhood and the County. Response: The proposed solar facility will have no negative impacts on the health, safety, or welfare of the inhabitants of the neighborhood or the County. Solar facilities produce no n oise, dust, pollution, fumes, or other negative impacts, and in general are a very good n eighbor to surrounding property owners. After the construction phase, the traffic is very minimal and limited to site visits for routine repairs and monitoring. There are no lights associated with the proposed facility, therefore, there will be no impact to the night sky or glare on adjacent properties. Solar facilities, such as the one proposed with this application, produce clean, renewable power, which is an alternative to traditional fossil fuels used to produce energy. To help minimize the visual impact to the one residence that is adjacent and 7 ISunShare COMMUNITY SOLAR 1724 Gilpin Street, Denver. CO 80218 • info@mysunshare.com • 800.793.0786 • MYSUNSHARE.COM to the west of the subject property, a screening of Rocky Mountain Junipers will be installed and maintained on a portion of the west boundary of the subject property. 25. Describe any irrigation features. If the proposed use is to be located in the A (Agricultural) Zone District, explain your efforts to conserve prime agricultural land in the locational decision for the proposed use. Response: SunShare, LLC will coordinate a water supply for the newly planted trees with the current tenant farmer. A watering schedule will be prepared to help ensure the trees survive and are maintained during the entire operation phase of the facility. The subject property is located in the "A" (Agricultural) Zone District. The proposed use is temporary and soils will not be disturbed or removed from the property. With the proposed solar facility being in place for up to forty (40) years, the land will lie fallow. Fallowing the land will allow the soil to rest and replenish nutrients, which can be leached from over -planting and regular irrigation. Fallowing the soil can cause potassium and phosphorus from deep below to rise toward the soil surface, where it can be used by crops later. Other benefits of fallowing soil are that it raises levels of carbon, nitrogen, and organic matter, improves moisture -holding capacity, and increases beneficial microorganisms in the soil. Once the economic viability of the solar facility is realized, the subject property will likely be returned to agricultural uses. 26. Explain how this proposal complies with Article V and Article XI of Chapter 23 if the proposal is located within any Overlay Zoning District (Airport, Geologic Hazard, or Historic Townsites Overlay Districts) or a Special Flood Hazard Area identified by maps officially adopted by the County. Response: The subject property is not located within any Overlay Zoning District or Special Flood Hazard Area. 27. Detail known State or Federal permits required for your proposed use(s) and the status of each permit. Provide a copy of any application or permit. Response: At this time, no known State or Federal permits will be required for the proposed use. During the review process, if any such permits are required, the associated application and permit will be provided to the Weld County Planning Department. Environmental Health Questions: 1. What is the drinking water source on the property? If utilizing a drinking water well, include either the well permit or well permit application that was submitted to the State Division of 8 j4tv I SunShare COMMUNITY SOLAR 1724 Gilpin Street, Denver, CO 80218 • info@mysunshare.com • 800.793.0786 • MYSUNSHARE.COM Water Resources. If utilizing a public water tap, include a letter from the water district, a tap or meter number, or a copy of the water bill. Response: Since this is an unmanned facility, no water supply is being proposed. During the construction phase of the project, the contractor will provide the work crew with potable water via portable water coolers. 2. What type of sewage disposal system is on the property? If utilizing an existing septic system provide the septic permit number. If there is no septic permit due to the age of the existing septic system, apply for a septic permit through the Department of Public Health and Environment prior to submitting this application. If a new septic system will be installed, please state "a new septic system is proposed". Only propose portable toilets if the use is consistent with the Department of Public Health and Environment's portable toilet policy. Response: Since this is an unmanned facility, no septic system is being proposed. During the construction phase, the contractor will provide a portable san-o-let for the construction crew. 3. If storage or warehousing is proposed, what type of items will be stored. Response: A steel container (8' X 40') is being proposed during the construction phase only to store equipment and spare parts for the solar facility. The container is to be positioned in the interior of the solar arrays, which should lessen its visual impact. The container will be painted a light tan to help blend the container with the natural environment. The container will be removed after construction phase is completed. 4. Describe where and how storage and/or stockpile of wastes, chemicals, and/or petroleum will occur on this site. Response: There will be no stockpiles of wastes, chemicals, or petroleum associated with this facility. 5. If there will be fuel storage on site, indicate the gallons and the secondary containment. State the number of tanks and gallons per tank. Response: There will be no fuel storage associated with this facility. Any fuel required during the construction phase will be brought to the site by fuel trucks, which will leave the site after the re- fueling is completed. 6. If there will be washing of vehicles or equipment on site, indicate how the wash water will be contained. Response: There will be no washing of vehicles or equipment on site, with the exception of washing mud from the tires of vehicles leaving the site during the construction phase. There will be a 25' X 16' track mat located near the access drive at Weld County Road 34. This mat will consist of 1-3" washed rock, 6" thick, over a Mirafi HP 270 Geotextile or equivalent base.

Describe the surrounding land uses of the site and how the proposed use is compatible with them. Response: To the north of the subject property, there is a 21.5 -acre oil/gas facility owned by Duke Energy Field Services, LP. The balance of the land to the north is 119.88 -acre parcel owned by Kerr-McGee Oil & Gas Onshore, LP which is vacant ground, except for three (3) oil/gas facilities. To the east of the subject property, there is a 557.69 -acre parcel that is owned by the State of Colorado. This parcel has multiple oil/gas facilities, an existing 2 MW community solar facility, and the balance on the land appears to be for agricultural uses. To the south of the subject property, there is a 161.41 -acre parcel that has an existing farmhouse and agricultural uses. There are also several oil/gas facilities on the property. To the west of the subject property there is a 75.81 -acre parcel that has an existing farmhouse and agricultural uses. The proposed community solar facility is very compatible with the surrounding uses. The proposed use has no odors or noise, and once the construction phase is completed, there will be very limited traffic associated with the use. The panels are coated with an anti -reflective technology to enhance their ability to capture sunlight, while minimizing reflective glare. The site will not require grading which will help minimize any negative drainage impacts to surrounding properties. Any areas that are disturbed during the construction phase will be re- seeded with native grasses and wildflowers. The existing farmhouse west of the proposed facility will be screened by the installation of Rocky Mountain Junipers, planted on the western edge of the subject property. Once the useful life of the facility is reached, the panels, racking, cables, and other equipment will be removed and the site returned to the condition it was in prior to the solar facility being built. 6. Describe the hours and days of operation (e.g. Monday thru Friday 8:00 a.m. to 5:00 p.m.). Response: Solar facilities are unmanned facilities that operate 24-7, but only produce power during the daylight hours. During the equipment delivery/construction phase, there will be a construction crew of approximately 20 full-time workers on the site. The site will be occupied Monday through Saturday, 8:00 A.M. to 5:00 P.M. during the construction phase. The 4.75 MW (AC), 4.99 MW (DC) facility will take approximately one -hundred nine (109) days to construct and interconnect.

This laydown/parking area will be approximately 50' X 250' in size and will be removed after the construction phase is completed. 13. Describe the method and time schedule of removal or disposal of debris, junk and other wastes associated with the proposed use. Response: During the construction phase, waste will be stored in refuge dumpsters, which will be emptied on a regular basis or as needed. Once the facility is operational, there will be no waste or refuge produced from the solar operation. Any waste or trash created while maintaining the facility will be removed from the site at the time the maintenance is performed. 14. Include a time -table showing the periods of time required for the construction of the operation. Response: The following is a schedule of time required for each phase of the construction operation: ■ Solar Facility Components First Deliver ■ Perimeter Fence Installation ■ Solar Panel Foundation Installation ■ Racking, Trenching, Wiring ■ Solar Panel Installation ■ Inspection & Set Meters ■ System Testing & Commissioning Day 1 Day 1 to Day 11 Day 1 to Day 30 Day 30 to Day 64 Day 64 to Day 94 Day 94 to Day 99 Day 99 to Day 109 15. Describe the proposed and existing lot surface type and the square footage of each type (i.e. asphalt, gravel, landscaping, dirt, grass, buildings). Response: The subject property is currently being farmed and will need to be re -seeded within the construction area. Following the completion of the construction for each phase, disturbed areas within the limits of construction, such as roadcuts, utility trenches, and other areas where vegetation has been removed, altered, or eliminated, will be reseeded with native grass seed and wildflower mix. There will be approximately 29,000 square feet of gravel access drive, including the hammerhead turn -around at the southern end of the access drive. In addition, there will be a gravel laydown area that is approximately 12,500 square feet, for a total of 41, 500 square feet of gravel surface area. There will be two (2) concrete transformer pads, each measuring approximately 48 square feet, for a total of 96 square feet of concrete area. Landscaping will be installed along the western border of the subject property. The actual square footage of landscaping will be determined during the USR application process. There are no existing buildings on the subject property and no new buildings are being proposed for the intended use. 4144 • SunShare COMMUNITY SOLAR 4 1724 Gilpin Street, Denver, CO 80218 • info@mysunshare.com • 800.793.0786 • MYSUNSHARE.COM 16. How many parking spaces are proposed? How many handicap -accessible parking spaces are proposed? Response: There will be two (2) internal parking spaces for vehicles servicing the facility. There will be no handicap -accessible parking spaces provided, as this is not a facility for general public use. 17. Describe the existing and proposed fencing and screening for the site including all parking and outdoor storage areas. Response: The two (2) internal parking spaces will be screened by the solar array. There will be no outdoor storage associated with this proposed solar facility. To comply with the National Electric Code, there will be an 8' tall game fence installed around the entire perimeter of the site. The fence and gate will be constructed of 4" X 4" welded rod material with a barbless wire apron extended out at a 45 -degree angle for the top 1' of fencing. The fence will be painted with a color to blend with the existing site conditions. 18. Describe the existing and proposed landscaping for the site. Response: The entire parcel has been used for agricultural purposes and is a dirt surface. Once the construction phase is completed, the area within the solar facility fence will be seeded with a native grasses and wildflower mixture. As previously mentioned, the closest residence to the proposed facility is a farmhouse located adjacent to the northwest corner of the subject property. To help minimize the visual impact to this residence, SunShare, LLC will install screening along the western border of the subject property, in the vicinity of the residence. This screening will consist of a game fence and planting Rocky Mountain Junipers, that will provide year-round screening of the proposed facility. SunShare, LLC will coordinate a water supply for the newly planted trees with the current tenant farmer. A watering schedule will be prepared to help ensure the trees survive and are maintained during the entire operation phase of the facility. 19. Describe reclamation procedures to be employed as stages of the operation are phased out or upon cessation of the Use by Special Review activity. Response: The subject property is currently being farmed and will need to be re -seeded within the construction area. Following the completion of the construction for each phase, disturbed areas within the limits of construction, such as roadcuts, utility trenches, and other areas where vegetation has been removed, altered, or eliminated, will be reseeded with native grass seed and wildflower mix. Once the useful life of the facility is realized, the panels, racking, cables, and 5 •Arve "1SunShare COMMUNITY SOLAR 1724 Gilpin Street, Denver, CO 80218 • info@mysunshare corn • 800 793 0786 • MYSUNSHARE.COM other equipment will be removed and the site returned to the condition it was in prior to the solar facility being built. 20. Describe the proposed fire protection measures. Response: The subject property is within the Platteville-Gilcrest Fire District service area. Fire access within the facility will be via a 20' -wide gravel driveway, with a hammerhead turn- around at the end of the drive. Grasses within the solar facility will be mowed as needed, to help prevent the spread of range fires. 21. Explain how this proposal is consistent with the Weld County Comprehensive Plan per Chapter 22 of the Weld County Code. Response: The Weld County Comprehensive Plan (Weld County Code, Chapter 22), addresses "Alternative Energy Resources — Goals and Policies". The proposed use of the subject property as a solar power generation facility is consistent with the goals and policies of this section. Alternative Energy Goal No. 1 is to "Support and encourage research, development and use of alternative energy sources". This proposed use is for the development and use of alternative energy sources by the citizens and business of Weld County. This facility will provide a clean, renewable energy source for citizens and businesses who are served by Xcel Energy. Alternative Energy Policy 1.5. Calls for supporting and developing the use of solar energy. This proposed use is in keeping with this policy. Recommended Strategy AE.1.5.b. proposes "Creating incentives that encourage large-scale commercial solar collections". The proposed project, would be considered a Medium -Scale Solar. Weld County recently reviewed its regulations regarding solar power generation facilities. Strategy AE.1.6.a. of Chapter 22 addresses this and recommends reviewing County regulations to ensure support of all alternative energy resources for small and large-scale applications. 22. Explain how this proposal is consistent with the intent of the zone district in which it is located. (Intent statements can be found at the beginning of each zone district section in Article Ill of Chapter 23 of the Weld County Code.) Sec. 23-3-10. - Intent. `Agriculture in the COUNTY is considered a valuable resource which must be protected from adverse impacts resulting from uncontrolled and undirected business. industrial and residential land USES. The A (Agricultural) Zone District is established to maintain and promote agriculture as an essential feature of the COUNTY. The A (Agricultural) Zone District is intended to provide areas for the conduct of agricultural activities and activities related to agriculture and agricultural production, and for areas for natural resource extraction and energy development, without the interference of other, incompatible land USES. 6 r • r • SunShare COMMUNITY SOLAR 1724 Gilpin Street, Denver, CO 80218 • info@mysunsharecom • 800.793.0786 • MYSUNSHARE.COM Response: The subject property is zoned Agricultural (A) and is within a "Non -Urbanizing Drainage Area". Medium -Scale Solar Facilities are permitted as a Use by Special Review in the Agricultural zone district. The Use by Special Review process allows for adequate review by the Planning staff, Planning Commission, and the Board of County Commissioners, to ensure compatibility with surrounding land uses. Additionally, citizens are afforded adequate opportunities to express their concerns in the public hearing setting before any solar facility can be constructed on agriculturally- zoned land. Within the stated intent of the "Agricultural" Zone District is the specific reference to "natural resource extraction" and "energy development". This proposed solar power generation plant is totally in compliance with the intent of the "Agricultural" Zone District. Solar facilities allow farmers and ranchers another use for their land and a viable stream of income beyond traditional farming and ranching uses. 23. Explain how this proposal will be compatible with future development of the surrounding area or adopted master plans of affected municipalities. Response: The subject property is just outside the Platteville Urban Growth Area. The Town of Gilcrest is to the north, but the subject property is not within the town's urban growth area. The comprehensive plans for Platteville and Gilcrest are both silent on renewable energy development, however they do encourage the development of oil/gas energy as part of their economic future. Weld County provided two (2) Notices of Inquiry for the Towns of Platteville and Milliken. The Town of Platteville has responded and is not interested in pursuing annexation at this time. The Town of Milliken has responded directly to the Weld County Planning staff. The proposed solar facility will be compatible with future development of the surrounding area. Much of the surrounding area is now and will probably remain agricultural in nature for the foreseeable future. In addition, oil/gas production will likely continue in the immediate area. Solar development is very compatible with farming and ranching uses and oil/gas development. Renewable projects provide farmers and ranchers a viable alternate use to traditional farming and ranching uses on their land. Since there are no permanent structures being built as part of this proposal, the land will be returned to its agricultural use once the e conomic viability of the solar facility has ended. 24. Explain how this proposal impacts the protection of the health, safety and welfare of the inhabitants of the neighborhood and the County. Response: The proposed solar facility will have no negative impacts on the health, safety, or welfare of the inhabitants of the neighborhood or the County. Solar facilities produce no n oise, dust, pollution, fumes, or other negative impacts, and in general are a very good n eighbor to surrounding property owners. After the construction phase, the traffic is very minimal and limited to site visits for routine repairs and monitoring. There are no lights associated with the proposed facility, therefore, there will be no impact to the night sky or 7 )1/4 • SunShare COMMUNITY SOLAR 1724 Gilpin Street, Denver, CO 80218 • info@mysunshare.com • 800.793.0786 • MYSUNSHARE.COM glare on adjacent properties. Solar facilities, such as the one proposed with this application, produce clean, renewable power, which is an alternative to traditional fossil fuels used to produce energy. To help minimize the visual impact to the one residence that is adjacent and to the west of the subject property, a screening of Rocky Mountain Junipers will be installed and maintained on a portion of the west boundary of the subject property. 25. Describe any irrigation features. If the proposed use is to be located in the A (Agricultural) Zone District, explain your efforts to conserve prime agricultural land in the locational decision for the proposed use. Response: SunShare, LLC will coordinate a water supply for the newly planted trees with the current tenant farmer. A watering schedule will be prepared to help ensure the trees survive and are maintained during the entire operation phase of the facility. The subject property is located in the "A" (Agricultural) Zone District. The proposed use is temporary and soils will not be disturbed or removed from the property. With the proposed solar facility being in place for up to forty (40) years, the land will lie fallow. Fallowing the land will allow the soil to rest and replenish nutrients, which can be leached from over -planting and regular irrigation. Fallowing the soil can cause potassium and phosphorus from deep below to rise toward the soil surface, where it can be used by crops later. Other benefits of fallowing soil are that it raises levels of carbon, nitrogen, and organic matter, improves moisture -holding capacity, and increases beneficial microorganisms in the soil. Once the economic viability of the solar facility is realized, the subject property will likely be returned to agricultural uses. 26. Explain how this proposal complies with Article V and Article XI of Chapter 23 if the proposal is located within any Overlay Zoning District (Airport, Geologic Hazard, or Historic Townsites Overlay Districts) or a Special Flood Hazard Area identified by maps officially adopted by the County. Response: The subject property is not located within any Overlay Zoning District or Special Flood Hazard Area. 27. Detail known State or Federal permits required for your proposed use(s) and the status of each permit. Provide a copy of any application or permit. Response: At this time, no known State or Federal permits will be required for the proposed use. During the review process, if any such permits are required, the associated application and permit will be provided to the Weld County Planning Department. 8 )1/4 • SunShare COMMUNITY SOLAR 1724 Gilpin Street, Denver, CO 80218 • info@mysunshare com • 800.793.0786 • MYSUNSHARE.COM Environmental Health Questions: 1.

' ; _, i ! ,' L / t , _iltis Date: Decommissioning Plan For a Medium -Scale Solar Facility Vasquez V In Compliance with: (Section 23-4-1030 B of the Weld County Code) Case Number: USR Number To be Determined Heirs of John F. Leonard (Parcel ID No. 121117000017) Prepared for: Weld County Department of Planning Services 1555 North 17th Avenue Greeley, CO 80631 Prepared by: SunShare, LLC Denver, Colorado '�SunShare COMMUNITY SOLAR Date Prepared: July, 2020 i.o Overview As a condition of approval for the 'Site -Specific Development Plan and Use by Special Review Permit, Weld County required that SunShare prepare a Decommissioning Plan for the solar facility, that is to be reviewed and approved by the Weld County Department of Planning Services. The intent of this Decommissioning Plan is to provide a comprehensive plan for removal of the solar facility after its useful life and/or the termination of power generation operations, and to return the subject property to conditions that existed prior to the solar facility's construction The solar power generation facility has an estimated useful life of 3o years or more, with an opportunity for a life of 5o years or more with equipment replacement and repowering At the end of the useful life of the facility, SunShare will cease power generation, decommission the facility, and remove the components of the facility from the subject property The site will be reclaimed and returned to the agricultural use that existed pnorto the facility being constructed This Decommissioning Plan is subject to refinement should future best practices or alternate methods be developed by the solar industry, during the life of this facility SunShare will follow solar industry standards' and best management practices (BMPs) that exist at the time of decommissioning and reclamation of the site 1.1 Procedures for Decommissioning the Solar Facility After Useful Life & Termination of Power Generation The solar facility consists of numerous recyclable materials, including glass, semiconductor material, steel, aluminum, copper, and plastics When the facility reaches the end of its operational life, the component parts can be dismantled, and for the most part, salvaged or recycled at properly licensed facilities Some site features, such as internal roads, driveways, drainage features/improvements, and electrical interconnections may remain on the site, depending upon the anticipated future use of the property All such improvements, that are scheduled to remain after the decommissioning of the site, will be approved by the Weld County Department of Planning Services. Page 3.of5 The following steps will be followed in the decommissioning of the solar facility. ▪ Approximately one year prior to the planned decommissioning of the facility, SunShare will schedule a pre -closure meeting with the Weld County Department of Planning Services to discuss the process for the site decommissioning and restoration The final decommissioning details will be developed through consultation with the Weld County Department of Planning Services and other departments and agencies that have jurisdiction over activities in the decommissioning process Any required permits will be obtained prior to implementation of the Decommissioning Plan • Appropriate temporary (construction -related) erosion and sedimentation control BMPs will be applied during the decommissioning phase of the project. The BMPs will be inspected on a regular basis to ensure proper functionality • Effectively, the decommissioning of the solar facility proceeds in reverse order of the installation 1 A site -specific health and safety plan shall be developed, prior to beginning decommissioning activities, which incorporates the specific sequence and procedures to be followed 2. Coordination with local departments and agencies to develop route plans and obtain necessary permits for the transportation of materials and equipment to and from the site 3 The solar facility shall be disconnected from the utility grid. This process will be coordinated with Xcel Energy 4 PV modules shall be disconnected, collected and transported to a properly licensed recycling facility 5 Above ground and underground electrical interconnection and distribution cabling shall be removed and salvaged or recycled off -site at an approved recycling facility 6 The aluminum racking that supports the PV modules shall be removed and salvaged or recycled off -site at an approved recycling facility 7 PV module support steel and support posts shall be removed and salvaged or recycled off -site at an approved recycling facility Page 2 of 5 8 Electrical and electronic devices, including transformers, semiconductors materials, inverters, and batteries, shall be removed and salvaged or recycled off - site at an approved recycling facility. 9. Concrete foundations shall be removed and will be recycled off -site at an approved concrete recycling facility 10 Fencing shall be removed and will be recycled off -site at an approved recycling facility 11 The site will be restored to its original condition, including any necessary sculpting of soils to match existing natural contours and the re -seeding of native grasses Any soil that had been re -located for construction purposes will be redistributed on the site or used for landscaping purposes Soils will be compacted for those areas where foundations or piers have been removed 1.2 Equipment to be Used for the Decommissioning of the Solar Facility The decommissioning of the solar facility will be undertaken using traditional heavy construction equipment, including front-end loaders, bull dozers, cranes, excavators (track - mounted and rubber -tired), water tankers, trucks, and pick-ups Semi -trucks will be used to transport materials to off -site salvage or recycle centers 1.3 Dust Mitigation During the Decommissioning Phase Water tankers will be used to help control dust while the decommissioning activities are occurring on the site During the decommissioning of the facility, SunShare will exercise BMPs to limit fugitive dust from being airborne and traveling beyond the property lines Dust control efforts will be monitored by the site foreman on a regular basis to ensure fugitive dust is adequately controlled Water spray will be applied, as needed, to unpaved areas during periods of dry weather Care will be taken not to over -apply water and create mud Vehicle tracking devices will be installed at truck exit drives, per the requirements of Weld County Vehicles operating on the site during the decommissioning phase will limit their speed to 15 mph or less, to minimize dust emissions Page 3 of 5 1.4 Financial Assurance to Cover the Decommissioning of the Solar Facility The capital investment represented by the solar facility and the long-term contracts to purchase the electricity generated, will create significant value. The materials used to construct the solar facility also have significant salvage value The salvage value of the electronics, semiconductor materials, aluminum, steel, and copper from the decommissioned facility, should cover most or all of the decommissioning cost In addition, SunShare will establish a decommissioning fund that will be contributed to on a regular basis, during the production phase of the facility Should the profits from the salvaged materials be less than the cost to decommission the facility, SunShare will pay for the balance of the decommissioning cost out of the decommissioning fund As a result, SunShare is respectfully requesting that financial assurance for the decommissioning of the solar facility be waived. 1.5 Signatures Prepared by.

TBPLS Firm #10074302 Stormwater Memo I Vasquez V November 2, 2020 Project Site This Drainage Report has been prepared on behalf of SunShare, LLC for the proposed construction of the Vasquez V Small Scale Solar Facility in Weld County, Colorado hereinafter referred to as the project. The proposed development is located in the NE1/4 Quarter of Section 17, Township 3 North, and Range 66 West of the 6th Prime Meridian. More specifically the Project site is approximately 27.2 acres of land and is located approximately 1.4 miles northeast of Platteville and approximately o.3 miles west of the Weld County Road (WCR) 29 and 34 intersection, State of Colorado. The site is covered intermittently with agricultural row crops depending on time of year. The ground surface slopes to the north at an average slope of approximately 0.20%. The site is within a FEMA Zone X, which is an area of minimal flood hazard. The site is therefore not within a loo -year flood plain. General Description of Project It is proposed to develop approximately 27.2 acres of land for the project of an approximate 5MW solar array. The solar array will deliver renewable energy to Xcel Energy under a 20 -year power purchase agreement (PPA). The facility is designed for un-manned operation except for bi-annual maintenance. Therefore, this facility will not represent any significant traffic impact to the surrounding county roads. Upon termination of the PPA, the improvements will be removed and the land will be restored to historic conditions. Drainage Design The area under and around the solar panels will be planted with low -maintenance grass seed mix. Very little additional impervious surface will be added to the site. The only new impervious surface is the gravel access road (32,278 ft^2) 2) and concrete inverter pads, which are 610 square feet, per Weld County solar panels are not considered impervious on A or B soils. Given this and based on conversations with County reviewers, the site will need not need a detention pond per Weld County requirements due to the minimal onsite addition of impervious and the access road being disconnected impervious surface. In Proposed Conditions runoff will continue to sheet flow to the northwest as it does in existing conditions. Historically stormwater runs northwest and then continues northwest. When the site is fully vegetated after construction, stormwater will flow off the solar panels, onto the ground, and run through the grass. The onsite soils, which are all categorized as hydrologic soil group A (Attachment 2), are conducive to infiltration. This soil type was also categorized as an open sandy loam. The fully vegetated site will slow runoff and encourage infiltration. Drainage Improvements There are no proposed drainage improvements on site. All existing flowpaths will be maintained and perennial vegetation will be planted onsite that will decrease runoff and encourage infiltration. 2 I Confidential and Proprietary. TBPLS Firm #10074302 Stormwater Memo I Vasquez V November 2, 2020 Adjacent Areas No channels flow through or adjacent to the project area. Minor runoff from the southern and eastern portions of the parcel sheet flows onto the project site and continues northwest. This water will pass through the basin. Onsite Soils The soils for this project site are classified as hydrologic soil group B (Attachment 4). The soil types found in the project site area are Olney sandy loam, 1 to 3 percent slopes. This soil information is based on the Natural Resources Conservation Service (NRCS) National Cooperative Soil Survey. The proposed vegetated conditions will slow run off and encourage infiltration. Timing/Phasing Schedule In the initial and interim stages, the contractor shall install silt fence, vehicle traction control and concrete washout at the entrance, and a stabilized staging area. In the final stage of construction, seeding and mulching and surface roughing shall be done in all disturbed areas, and erosion control blankets shall be installed on all slopes greater than 4:1. The contractor shall also remove the vehicle traction control, concrete washout, stabilized staging area, erosion control blanket, and silt fence in the final stage of construction. BMP Installation, Inspection, and Removal BMPs will be installed prior to project construction, with the exception of the BMPs in the final stage. BMPs will be inspected weekly and as required by the County through project completion by the contractor. BMPs will be maintained and remain in place at least until construction is finished and the site is vegetated. Once all exposed areas have been covered, the BMPs may be removed. Since the project does not include any other disturbance, no additional site stabilization is necessary and/or warranted. Permanent Stabilization The project will be seeded with the Weld County's upland rea seed mix to establish permanent stabilization after construction activity has ceased. Reference the table on sheet 13-66 of Appendix A in the USDCM Manual, Volume 2, Chapter 13. As per the USDCM Manual, permanent seeding involves the loosening of soil, applying topsoil, drill seeding the disturbed areas to a depth not less than 1/4 inch and not more than 3/4 inch, and crimping the seeded areas in straw mulch at a rate of 2 tons per acre to provide immediate erosion protection. Summary The proposed site will be designed to maintain its existing drainage patterns. Due to the limited amount of impervious surface proposed and the proposed conversion of the site from row crops to the vegetated cover under the panels a decrease in runoff rates is expected for the proposed conditions when compared to existing conditions. Water quality will be provided by the disconnected impervious and the proposed vegetation below the panels. 3 I Confidential and Proprietary. TBPLS Firm #10074302 Stormwater Memo I Vasquez V November 2 . 2020 Based on the landcover conversion and the addition of the detention pond the site design will adequately protect public health, safety, and general welfare and will have no adverse impacts on public right-of-way or offsite properties. 4 I Confidential and Proprietary.

TYPICALLY RANKING IN THE TOP TEN COUNTIES IN THE COUNTRY IN TOTAL MARKET VALUE OF AGRICULTURAL PRODUCTS SOLD, THE RURAL AREAS OF WELD COUNTY MAY BE OPEN AND SPACIOUS. BUT THEY ARE INTENSIVELY USED FOR AGRICULTURE PERSONS MOVING INTO A RURAL AREA MUST RECOGNIZE AND ACCEPT THERE ARE DRAWBACKS, INCLUDING CONFLICTS WITH LONG-STANDING AGRICULTURAL PRACTICES AND A LOWER LEVEL OF SERVICES THAN IN TOWN ALONG WITH THE DRAWBACKS COME THE INCENTIVES WHICH ATTRACT URBAN DWELLERS TO RELOCATE TO RURAL AREAS OPEN VIEWS. SPACIOUSNESS, WILDLIFE. LACK OF CITY NOISE AND CONGESTION, AND THE RURAL ATMOSPHERE AND WAY OF LIFE. WITHOUT NEIGHBORING FARMS. THOSE FEATURES WHICH ATTRACT URBAN DWELLERS TO RURAL WELD COUNTY WOULD QUICKLY BE GONE FOREVER AGRICULTURAL USERS OF THE LAND SHOULD NOT BE EXPECTED TO CHANCE THEIR LONG-ESTABLISHED AGRICULTURAL PRACTICES TO ACCOMMODATE THE INTRUSIONS OF URBAN USERS INTO A RURAL AREA WELL -RUN AGRICULTURAL ACTIVITIES WILL GENERATE OFF -SITE IMPACTS. INCLUDING NOISE FROM TRACTORS AND EQUIPMENT. SLOW -MOVING FARM VEHICLES ON RURAL ROADS, DUST FROM ANIMAL PENS, FIELD WORK, HARVEST AND GRAVEL ROADS, ODOR FROM ANIMAL CONFINEMENT, SILAGE AND MANURE. SMOKE FROM DITCH BURNING. FLIES AND MOSQUITOES. HUNTING AND TRAPPING ACTIVITIES: SHOOTING SPORTS, LEGAL HAZING OF NUISANCE WILDLIFE, AND THE USE OF PESTICIDES AND FERTILIZERS IN THE. FIELDS, INCLUDING THE USE OF AERIAL SPRAYING IT IS COMMON PRACTICE FOR AGRICULTURAL PRODUCERS TO UTILIZE AN ACCUMULATION OF AGRICULTURAL MACHINERY AND SUPPLIES TO ASSIST IN THEIR AGRICULTURAL OPERATIONS A CONCENTRATION OF MISCELLANEOUS AGRICULTURAL MATERIALS OFTEN PRODUCES A VISUAL DISPARITY BETWEEN RURAL AND URBAN AREAS OF THE COUNTY SECTION 35-3.5-102, C.R.S., PROVIDES THAT AN AGRICULTURAL OPERATION SHALL NOT BE FOUND TO BE A PUBLIC OR PRIVATE NUISANCE IF THE AGRICULTURAL OPERATION ALLEGED TO BE A NUISANCE EMPLOYS METHODS OR PRACTICES THAT ARE COMMONLY OR REASONABLY ASSOCIATED WITH AGRICULTURAL PRODUCTION WATER HAS BEEN, AND CONTINUES TO BE, THE LIFELINE FOR THE AGRICULTURAL COMMUNITY IT IS UNREALISTIC TO ASSUME THAT DITCHES AND RESERVOIRS MAY SIMPLY BE MOVED "OUT OF THE WAY" OF RESIDENTIAL DEVELOPMENT. WHEN MOVING TO THE COUNTY, PROPERTY OWNERS AND RESIDENTS MUST REALIZE THEY CANNOT TAKE WATER FROM IRRIGATION DITCHES, LAKES OR OTHER STRUCTURES, UNLESS THEY HAVE AN ADJUDICATED RIGHT TO THE WATER WELD COUNTY COVERS A LAND AREA OF APPROXIMATELY FOUR THOUSAND (4,000) SQUARE MILES IN SIZE (TWICE THE SIZE OF THE STATE OF DELAWARE) WITH MORE THAN THREE THOUSAND SEVEN HUNDRED (3,700) MILES OF STATE AND COUNTY ROADS OUTSIDE OF MUNICIPALITIES THE SHEER MAGNITUDE OF THE AREA TO BE SERVED STRETCHES AVAILABLE RESOURCES. LAW ENFORCEMENT IS BASED ON RESPONSES TO COMPLAINTS MORE THAN ON PATROLS OF THE COUNTY, AND THE DISTANCES WHICH MUST BE TRAVELED MAY DELAY ALL EMERGENCY RESPONSES. INCLUDING LAW ENFORCEMENT, AMBULANCE AND FIRE. FIRE PROTECTION IS USUALLY PROVIDED BY VOLUNTEERS WHO MUST LEAVE THEIR JOBS AND FAMILIES TO RESPOND TO EMERGENCIES. COUNTY GRAVEL ROADS, NO MATTER HOW OFTEN THEY ARE BLADED, WILL NOT PROVIDE THE SAME KIND OF SURFACE EXPECTED FROM A PAVED ROAD. SNOW REMOVAL PRIORITIES MEAN THAT ROADS FROM SUBDIVISIONS TO ARTERIALS MAY NOT BE CLEARED FOR SEVERAL DAYS AFTER A MAJOR SNOWSTORM. SERVICES IN RURAL AREAS, IN MANY CASES, WILL NOT BE EQUIVALENT TO MUNICIPAL SERVICES. RURAL DWELLERS MUST, BY NECESSITY. BE MORE SELF-SUFFICIENT THAN URBAN DWELLERS PEOPLE ARE EXPOSED TO DIFFERENT HAZARDS IN THE COUNTY THAN IN AN URBAN OR SUBURBAN SETTING FARM EQUIPMENT AND OIL FIELD EQUIPMENT, PONDS AND IRRIGATION DITCHES, ELECTRICAL POWER FOR PUMPS AND CENTER PIVOT OPERATIONS, HIGH-SPEED TRAFFIC, SAND BURS, PUNCTURE VINES, TERRITORIAL FARM DOGS AND LIVESTOCK AND OPEN BURNING PRESENT REAL THREATS.

Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation. are thoroughly wet, and receive precipitation from long -duration storms. The soils in the United States are assigned to four groups (A, B, C. and D) and three dual classes (A/D. B/D. and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep. well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep. moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink -swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (A/D.

TBPLS Firm #10074302 Drainage Report I Vasquez V July 21, 2020 Project Site This Drainage Report has been prepared on behalf of SunShare, LLC for the proposed construction of the Vasquez V Small Scale Solar Facility in Weld County, Colorado hereinafter referred to as the project. The proposed development is located in the NE1/4 Quarter of Section 17, Township 3 North, and Range 66 West of the 6th Prime Meridian. More specifically the Project site is approximately 27.2 acres of land and is located approximately 1.4 miles northeast of Platteville and approximately 0.3 miles west of the Weld County Road (WCR) 29 and 34 intersection, State of Colorado. The site is covered intermittently with agricultural row crops depending on time of year. The ground surface slopes to the north at an average slope of approximately 0.20%. The site is within a FEMA Zone X, which is an area of minimal flood hazard. The site is therefore not within a loo -year flood plain. General Description of Project It is proposed to develop approximately 27.2 acres of land for the project of an approximate 5MW solar array. The solar array will deliver renewable energy to Xcel Energy under a 20 -year power purchase agreement (PPA). The facility is designed for un-manned operation except for bi-annual maintenance. Therefore, this facility will not represent any significant traffic impact to the surrounding county roads. Upon termination of the PPA, the improvements will be removed and the land will be restored to historic conditions. Drainage Design The area under and around the solar panels will be planted with low -maintenance grass seed mix. Very little additional impervious surface will be added to the site. The only new impervious surface is the gravel access road and concrete inverter pads, which are approximately 32,278 square feet and 610 square feet, respectively per Weld County solar panels are not considered impervious on A or B soils. Given this, the site will need a detention pond per Weld County requirements. In Proposed Conditions runoff will continue to sheet flow to the northwest as it does in existing conditions. Historically stormwater runs northwest and then continues northwest. When the site is fully vegetated after construction, stormwater will flow off the solar panels, onto the ground, and run through the grass. The onsite soils, which are all categorized as hydrologic soil group B (Attachment 4), are conducive to infiltration. This soil type was also categorized as a loamy sand and sandy loam for the runoff coefficient. The fully vegetated site will slow runoff and encourage infiltration. Stormwater Runoff Analysis A detention pond has been sized to store the stormwater runoff generated by the 1 -hour, 100 - year storm falling on the developed site and release of the detained water at the historic runoff rate of the i-hour, 1O -year storm falling on the undeveloped site for non -urbanizing areas. Historic is defined as an undeveloped site with a 2.0% imperviousness. The Rational Method was used to determine the runoff rates for the project. These can be found in Attachment 3. 2 ( Confidential and Proprietary. TBPLS Firm #10074302 Drainage Report I Vasquez V Water Quality The project needs to treat the Water Quality Capture Volume (WQCV) for the added imperviousness of the project area per the USDCM Volume 3 Section 3. Using the equation in the manual a WQCV that needs to be captured based on a site imperviousness of 3% is .022 watershed inches which requires a BMP storage of 0.051 ac -ft. This storage amount will be counted in the detention pond design. The water quality volume must be detained over 40 hours. Drainage Improvements There only proposed drainage improvements onsite is the required detention pond. The onsite detention pond was sized using the MHFD Detention Spreadsheet which can be found in Attachment 3 showing all necessary calculations. The pond exceeds the required volume of 0.645 ac -ft. Adjacent Areas No channels flow through or adjacent to the project area. Minor runoff from the southern and eastern portions of the parcel sheet flows onto the project site and continues northwest. This water will pass through the basin. Onsite Soils The soils for this project site are classified as hydrologic soil group B (Attachment 4). The soil types found in the project site area are Olney sandy loam, 1 to 3 percent slopes. This soil information is based on the Natural Resources Conservation Service (MRCS) National Cooperative Soil Survey. The runoff coefficient typically referred to as a "C" value in Attachment 3 is almost identical in proposed conditions as in existing conditions. The proposed vegetated conditions will slow run off and encourage infiltration. Methodologies Used For Drainage Report and Analysis The site does not qualify for an exemption to the stormwater detention requirement based on the Weld County ordinance for B soils due to the amount of added impervious area. This requires the site to have a detention basin. Existing and proposed discharge rates were calculated using the Rational Method. The Rational method uses a runoff coefficient which is commonly referred to as a C value. This is not a soil type, but a value used to describe to runoff rates of different land covers. Rainfall data was obtained from NOAA Atlas 14 and utilized a site - specific nested rainfall distribution (Attachment 2). Minimal grading is proposed to meet the tolerances of the proposed solar array. Drainage patterns will remain the same with the addition of the basin that outlets similar to existing conditions. Minimal grading is proposed onsite and drainage conditions will remain the same as existing. Offsite drainage area remains the same as existing conditions. Timing/Phasing Schedule In the initial and interim stages, the contractor shall install silt fence, vehicle traction control and concrete washout at the entrance, and a stabilized staging area. In the final stage of construction, seeding and mulching and surface roughing shall be done in all disturbed areas, 3 I Confidential and Proprietary. MKS Firm #10074302 Drainage Report I Vasquez V and erosion control blankets shall be installed on all slopes greater than 4:1. The contractor shall also remove the vehicle traction control, concrete washout, stabilized staging area, erosion control blanket, and silt fence in the final stage of construction. BMP Installation, Inspection, and Removal BMPs will be installed prior to project construction, with the exception of the BMPs in the final stage. BMPs will be inspected weekly and as required by the County through project completion by the contractor. BMPs will be maintained and remain in place at least until construction is finished and the site is vegetated. Once all exposed areas have been covered, the BMPs may be removed. Since the project does not include any other disturbance, no additional site stabilization is necessary and/or warranted. Permanent Stabilization The project will be seeded with the Weld County's upland rea seed mix to establish permanent stabilization after construction activity has ceased. Reference the table on sheet 13-66 of Appendix A in the USDCM Manual, Volume 2, Chapter 13. As per the USDCM Manual, permanent seeding involves the loosening of soil, applying topsoil, drill seeding the disturbed areas to a depth not less than 1/4 inch and not more than 3/4 inch, and crimping the seeded areas in straw mulch at a rate of 2 tons per acre to provide immediate erosion protection. Summary The proposed site will be designed to maintain its existing drainage patterns. Due to the limited amount of impervious surface proposed and the proposed conversion of the site from row crops to the vegetated cover under the panels along with the proposed detention pond, a decrease in runoff rates is expected for the proposed conditions when compared to existing conditions. Water quality will be provided by the disconnected impervious and the proposed vegetation below the panels along with the detention pond. Based on the landcover conversion and the addition of the detention pond the site design will adequately protect public health, safety, and general welfare and will have no adverse impacts on public right-of-way or offsite properties. 4 I Confidential and Proprietary.

Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long -duration storms. The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (A/D, B/D. and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink -swell potential. soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes. 100.0% USDA Natural Resources Web Soil Survey dam Conservation Service National Cooperative Soil Survey 7/21/2020 Page 3 of 4 Hydrologic Soil Group Weld County, Colorado.

Leonard Prepared for: Weld County Department of Planning Services 1555 North 17th Avenue Greeley, CO 80631 Prepared by: SunShare, LLC Denver, Colorado J4 4 '�SunShare COMMUNITY SOLAR i.o Overview As a condition of approval for the Site -Specific Development Plan and Use by Special Review Permit, Weld County required that SunShare prepare a Property Maintenance Plan for the solar facility, that is to be reviewed and approved by the Weld County Department of Planning Services The intent of this Property Maintenance Plan is to provide a comprehensive plan for control of dust, noxious weeds, and any drainage issues that could cause erosion from the solar facility 1.1 Dust Mitigation During the Construction Phase Water tankers will be used to help control dust while the construction activities are occurring on the site During the construction of the facility, SunShare will exercise BMPs to limit fugitive dust from being airborne and traveling beyond the property lines Dust control efforts will be monitored bythe site foreman on a regular basis to ensure fugitive dust is adequately controlled Water spray will be applied, as needed, to unpaved areas during periods of dry weather Care will be taken not to over -apply water and create mud Vehicle tracking devices will be installed at truck exit drives, per the requirements of Weld County Vehicles operating on the site during the construction phase will limit their speed to 15 mph or less, to minimize dust emissions 1.2 Noxious Weed Management The Colorado Department of Agriculture (CDA) and Weld County, both require landowners to prevent the spread of State Listed Noxious Weeds Construction activities on the site have the potential to introduce new noxious weed species to the site, or spread existing species on to or off of the site This noxious weed management program was developed to prevent further spread of noxious weeds SunShare will comply with CDA and Weld County regulations through implementation of this plan Periodic reviews and updates to this plan will be completed as necessary to keep it current with noxious weed control issues This plan will be implemented throughout the life of the solar facility Appropriate management actions will be implemented whenever noxious weed species are observed growing within the project area The goals of weed management are to 1) Identify and manage noxious weeds within and immediately adjacent to the project areas to be disturbed and after the area has been reclaimed, z ) Conduct pre-treatment and post -treatment evaluations, and continue or modify treatment measures as necessary, 3 ) Minimize the potential for transportation and importation of noxious weed species, 2 4) Educate field personnel in order to encourage compliance with weed management program goals and assist with identification and control efforts To prevent or minimize the infestation and spread periodic inspections of the project area during the beginning, middle, and end of the growing season will evaluate presence or absence, degree of invasion, and the response of previous treatments SunShare's operational staff will conduct regular site inspections and ensure implementation of this plan Specific treatment methodologies and timetables will be developed based on species of concern, location and extent of the infestation(s), and other pertinent factors 1.2 (a) Noxious Weed Prevention Noxious weeds are spread through dispersal of seed and/or transport of plant propagules (i e spores, seeds, roots, etc ) The most effective way to control noxious weeds is to prevent their introduction into the site in the first place A combination of methods and practices will be employed to prevent the introduction of weed species and their regeneration within the project area The following methods and practices may be employed, either singly or in combination, to prevent the introduction of weeds into the solar site 1 ) Athorough cleaning of equipment will be conducted before entering the project area to prevent the introduction of seed and plant propagules from other sites, z ) Seed mixtures used for revegetation or temporary site stabilization will be free of noxious weeds, 3) Hay, straw, and/or other materials used for mulch or other purposes will be certified weed free, 4 ) A periodic inspection will be conducted to identify any new weed infestations that may have occurred Any new infestations will be scheduled for management before they become well established and/or spread, 5 ) Communication and coordination with adjacent land holders whose property is infested with noxious weeds that may threaten the site should occur Establishing partnerships for weed management within the local area is essential for successful long-term weed management, 6) Noxious and pest weed infestations that threaten natural and reclaimed areas will be treated with accepted Integrated Weed Management (IWM) methods These methods are further discussed below 1.2 (b) Integrated Weed Management (IWM) An Integrated Weed Management approach will be implemented for treatment of noxious weeds within the project area An IWM approach enables selection of one or more weed 3 management methods based on site specific environmental conditions and control needs The following weed management methods will be considered for the project area 1) Cultural — Planting native or desirable plant species for site colonization and promoting healthy vegetation communities in reclaimed areas Prevent unnecessary disturbance through precise planning of construction projects and other activities Prompt revegetation of disturbed areas z ) Mechanical — Mowing, pulling, disking, and plowing may be used on weedy species for which these treatments are effective 3) Biological — Introduction of insects or other biologic agents which are known to inhibit or prevent reproduction of noxious weed species If biological agents are employed, control methods will be coordinated with the Colorado Department of Agricultural Insectary in Palisade, Colorado 4) Chemical — Application of appropriate herbicides by a licensed applicator All herbicides will be applied in accordance with the manufacturer's label and in accordance with Colorado laws In some cases, only one control method may be warranted, while in other cases a combination of control methods may be appropriate Control methods selected will be dependent upon species of concern, and the location and extent of the infestation The use of IWM methods will protect pollinators, reduce hazards to wildlife, reduce the possibility of herbicide resistance, and minimize persistence and mobility of herbicides in the soil Weed control methods and practices will be applied in a manner that conforms to applicable federal, state, and local laws 1.2 (b) 1— Cultural Control Germination and establishment of noxious weeds can be reduced by following accepted revegetation and vegetation management techniques that favor the growth of desirable plants These include prompt seeding and revegetation of disturbed areas with appropriate seed mixes, maintaining optimum fertility and moisture levels, planting at optimum density of pure live seed, minimizing use of fertilizers, and selecting suitable species for revegetation Minimizing areas of disturbance and exposed soil prevents opportunities for aggressive species to establish A revegetation plan has been developed for the site that utilizes native species that are well - adapted to the site Seeding native species in conjunction with other management practices will provide some level of competition with noxious weeds, and minimize the opportunity for new infestations to become established 4 1.2 (b) 2 — Mechanical Control Mechanical Control of noxious weeds can be an effective tool to physically disrupt noxious weed growth and seed development A combination of mechanical methods may be used including tilling or disking, mowing, hand-held weed trimmers, mulching, hand -pulling, hoeing, or livestock grazing Mechanical weed control practices must be applied with correct timing to maximize their effectiveness in preventing vegetation development or seed production Annual weedy species may be readily controlled with mowing or physical removal Perennial species such as Dalmatian toadflax have extensive root systems For such weed species, mowing may only control seed production without seriously affecting the plant's survival Mowing after seed production has occurred may spread the plants Disking or tilling areas containing perennial noxious species may increase the area of infestation due to root sprouting In most cases, mechanical control methods used alone are not effective against noxious weed species 1.2 (b) 3 — Biological Control Biological control of noxious weeds can be an effective tool to physically disrupt plant growth and seed development A combination of biological methods may be used including introduction of insect weed predators and species specific plant diseases Biological weed control methods and practices will be applied with appropriate timing to maximize their effectiveness in preventing seed production It must be noted that the use of biological controls normally does not eradicate an infestation of weeds, rather they are capable of reducing weed species vigor and reproduction The Colorado Department of Agriculture's Biological Pest Control Program has on -going biological control programs for several noxious weed species Note, the use of insect bio-controls typically require large populations of the target weed to sustain the population of bio-control agents Biological controls should not be expected to eliminate the entire infestation of a noxious weed, but instead to bring the infestation down to a more manageable level 1.2 (b) 4 — Chemical Control Chemical control of noxious and pest weeds can be an effective tool to disrupt plant growth and seed development Herbicides can kill targeted species, prevent development and/or germination of noxious weed seed, can be used with minimal disturbance to soils, and in some cases, can be selective to specific species or groups of plants Herbicides must be applied at the appropriate time to maximize their effectiveness in preventing seed production, for disrupting plant establishment and growth, or achieving kill of noxious species To avoid development of resistance to a particular herbicide through repeated use over prolonged periods of time, 5 herbicides with varying modes of action to be used Also, herbicides will be applied according to manufacturer's label recommendations (i e application rate, method, and timing) to prevent development of plant resistance Herbicide selection will be based on weed emergence, timing of application, past applications, and ground and weather conditions during the applications Successful IWM begins with an understanding of the target plant species and the environment within which it grows Next, the physiologic effects of an herbicide on plant growth and development must be understood Understanding a pesticide's chemical nature is also important in minimizing impacts to non -target species, the applicator, endangered species, and pollinators, as well as surface water runoff hazards and leaching into groundwater Every herbicide label contains information regarding environmental hazards This information will be evaluated for each herbicide considered for use at the site and herbicides will be selected which pose minimal to no environmental hazards All pesticides will be handled with care, and applied by qualified personnel Properly identifying the weed problem and the most effective chemical control method for use during the plant growth cycle is critical to effective weed control Equipment will be properly calibrated before herbicides are applied and appropriate Personal Protective Equipment (PPE) will be used Empty containers will be disposed of promptly, safely and according with product labeling Herbicides vary in the amount of time after an application before it is safe to re-enterthe treated area without protective clothing and equipment The site re-entry time is affected by the rate of application, size of the area treated and the amount of time to be spent in the field For the safety of employees and contractors, the Restricted Entry Interval (REI) listed on the herbicide's label will be followed Appropriate herbicide application records will be maintained as specified by the CDA 1.2 (c) — Monitoring and Follow -Up Even with effective weed management strategies, it often takes several seasons to eradicate or bring weed populations to an acceptable level With well -established infestations, it is likely that a seed bank has developed in the soil capable of producing new plants for many years An infestation of weeds can easily re -invade treated areas in one growing season if control and treatment activities are prematurely curtailed Weed management efforts should be carried out over an adequate number of growing seasons to realize effective weed management within the target area As with all weed management, this multi -season effort is best served by effective documentation of control efforts and continued vigilance in successive seasons of management Information can be used to modify treatment priorities and weed management strategies over time Vigilance is required against new infestations that may be moving into the site These new sources of infestation may be worked into prevention and management plans as necessary 6 This weed management plan will be modified over time as site conditions change. Weed management strategies and priorities can be modified as weed infestations change in response to continued control efforts. 1.3 — Drainage and Erosion Control Installation of the solar facility will not alter existing drainage patterns or flow rates on the site and runoff water quality will not be impacted by the solar facility components. Installation of water quality or detention facilities would require clearing, grubbing, grading and reseeding of a portion of the site and would likely increase the potential for erosion, sediment transport and concentrated flow. Accordingly, water quality and detention are not recommended for this project. Appropriate temporary (construction -related) erosion and sedimentation control Best Management Practices (BMPs), will be applied during the construction phase of the project. The BMPs will be inspected on a regular basis to ensure proper functionality. 1.4 - Signatures Prepared by: «s/ertif' /%llr Richard L.

T.100 USE BY SPECIAL REVIEW TRAFFIC NARRATIVE for a Medium -Scale Solar Facility In partial fulfillment of Weld County's Use by Special Review Permit requirements, this Traffic Narrative has been prepared for the proposed Medium -Scale Solar Facility located west of the southwest corner of WCR 34 and WCR 29 (the Project). This narrative is intended to provide traffic -related information and identify potential Project impacts to affected roadways within Weld County and in and around the Town of Platteville. The following information is included in this narrative: • Project Location, Components and Construction Schedule • Designated Travel Route • Daily Vehicle Trip Generation • Conclusions Project Location, Components and Construction Schedule Location - The Project will occupy approximately 32.378 acres of the +/- 159.33 acre leased area (within Weld County Parcel No. 121117000017), located west of the southwest corner of WCR 34 & WCR 29 in the northeast quarter of Section 17, Township 3N, Range 66W. Components - The Project generally includes: 4.75 MW (AC) or 4.99 MW (DC) solar energy conversion system comprised of 13,050 tracker solar modules mounted on steel l -beams; concrete pad -mounted transformer and interconnect; inverters mounted at the end of array rows; an access drive with emergency turn around; and perimeter fence with gate. Construction Schedule — Once the Use by Special Review Permit is finalized, the construction phase is anticipated to take approximately one hundred and nine (109) days. Based on this, the following preliminary schedule has been prepared: • Solar Facility Components First Deliver • Perimeter Fence Installation • Solar Panel Foundation Installation • Racking, Trenching, Wiring • Solar Panel Installation • Inspection & Set Meters Day 1 Day 1 to Day 11 Day 1 to Day 30 Day 30 to Day 64 Day 64 to Day 94 Day 94 to Day 99 ...44 410„ ) 4_ I SunShare COMMUNITY SOLAR 1724 Gilpin Street, Denver, CO 80218 • info@mysunshare.com • 800.793.0786 • MYSUNSHARE.COM • System Testing & Commissioning Day 99 to Day 109 Designated Travel Route The designated travel route includes: State Highway 85 north to WCR 34, then east approximately one (1) mile to the Project access drive. The following is a brief description of the access route roadways. State Highway (SH) 85 — In the vicinity of Platteville, SH 85 is a four -lane divided highway with a posted speed limit of 55 mph. The SH 85/WCR 34 intersection is not signalized and has dedicated right and left-hand turn lanes. The road surface appears to be in good condition. Project -related traffic is not expected to impact SH 85. WCR 34 - The one (1) mile segment of WCR 34 included in the travel route is generally a +/- 24' -wide gravel road with varying gravel shoulder width. The posted speed limit is 30 mph in the vicinity of the Project site. The road surface appears to be in fair condition. Daily Vehicle Trip Generation and Distribution Project development may be divided into the following 3 phases: material and equipment delivery; facility construction; and facility maintenance). The following Table 1 illustrates the estimated average daily trip generation by vehicle type for each Project phase. Project Phase Vehicle Type Estimated Vehicle Gross Weight Number of Vehicles Per Day Average Maximum and Vehicle Trips Per Day (Time) Equipment (approx. Material 1 and Delivery week) Conex Delivery Container Trucks and 30,000-50,000 lbs 5-10 10-20 Equipment Trucks Hauling 20,000-40,000 lbs 0-2 0-4 4 Max — 24/Ave - 16 Facility Construction Passenger Vehicles 2,000 to 10,000 lbs 5-12 10-24 (3-4 months) Fuel Truck 20,000 to 30,000 lbs 1 2 Material Delivery Truck 20,000 to 30,000 lbs 1 a 2 _ - Max — 28/Ave - 20 Operations (ongoing once operational) Utility Vehicle Truck) (Pickup 2,000 to 10,000 lbs 2 per quarter or less Quarter/Ave Max — 2 per - 0 As illustrated in Table 1, the majority of traffic generated will occur during the 3 4 month construction period (Max 28/Ave 20vtpd). This traffic will generally be construction crew passenger vehicles. i • SunShare COMMUNITY SOLAR 1724 Gilpin Street, Denver, CO 80218 • info@mysunshare.com • 800.793.0786 • MYSUNSHARE.COM The majority of heavy truck traffic including Conex container delivery (30-50 Conex containers/delivery trucks) and equipment (rubber tire loader, pile driver, forklift) delivery, and pickup will travel to and from the Project between 8:00 AM and noon and 1:00 PM and 4:30 PM. Project -related traffic during all phases will not be significant during AM and PM peak periods (7:30 — 9:00 AM and 4:30 — 6:00 PM, respectively). Conclusions 1. The Project is expected to generate up to 24 vehicle trips per day during material and equipment delivery (anticipated to be one week at the beginning of the Project and one week at the end of the Project), 24 vehicle trips per day during the construction phase (3-4 months) and typically, 2 vehicle trips per quarter for routine maintenance after the system is operational. 2. Project construction is anticipated to begin in January 2021 (material and equipment delivery) and end in early May 2021 (solar facility start-up and container and equipment container pick-up). The phase with the greatest amount of traffic (construction phase) is expected to occur over a 3 to 4 -month period. 3. Daily Project -related truck traffic is not expected to impact AM and PM peak traffic periods. 4. As proposed, the solar facility installation (material/equipment delivery — approximately 1 week, solar facility installation - 3 months and solar facility operations - ongoing) is not anticipated to create adverse traffic -related impacts on Weld County roads. Based on anticipated vehicle type and weight (from Table 1), the Project is not anticipated to degrade/damage Weld County roads. a�SunShare COMMUNITY SOLAR 1724 Gilpin Street, Denver, CO 80218 • info@mysunshare.com • 800.793.0786 • MYSUNSHARE.COM November 30th, 2020 To Whom It May Concern, My Name is Graham Carr and I manage the farm operations for the property under review today and have done so for over fifteen years My wife, Paula, is one of the owners Before Paula, I managed this for her Mother, Patti Wilcox Patti lived in Washington state and was not able to take care of the property from that distance Likewise, the other property owners, family members were not taking care of the property Patti's parents, John & Mirth Leonard, originally purchased this property on April 6, 1951, when he was 43 years old It is my understanding John stopped farming around 1980 John passed away on 5/18/1994 Before I took over in 2005, the owners had unsuccessfully tried to work with a tenant farmer but for the most part, the land becomes overrun with noxious weeds The only activity was from oil and gas production The first well was drilled on 10/1/1975 Six shallow vertical wells were drilled on the property Five of the wells stopped producing during 1999 The last well stopped production on 1/2010 Five of the wells have been completely removed and plugged/Abandoned I received notice on 10/5/2020 from Crestone Peak will start the well Plug & abandon operations As of 11/15/2020, the work had not started, but this is on the schedule for completion Since we had lost all the shallow vertical wells, I reached out to Kerr-McGee and Anadarko during 2018 in hopes to arrange for a new multi -horizontal Oil & Gas pad to be placed on our property I was told by Brandon McGraw (Landman) from Anadarko that they were currently in the permitting phase for developing this area sometime in 2019 There are wells planned to develop NE/4 Sec 17 but will be reached from another surface parcel, but the wellbores will pass under our property Currently, we are surrounded by horizontal wellbores on the East, South, and West sides The only remaining open area for wellbores is below our property The most logical location for a new pad would be on the south end of Section 17 The bores would have to run North under us and could extend to the center of Section 36 This would give a 1 5 -mile -long bore The opportunity to develop our property for oil and gas is no longer an option Below is a table showing the O&G well information Farming operation When I took over the farm management, the Olson family was occasionally using the property for growing feed, but this was hit and miss The property had fallen into poor condition I made numeious attempts to work with the Olson to encourage them to start working on the property to get it back to quality farmland That failed so during 2014 I reached out to Gary from Bella Farms I offered Gary free rent for 5 years to offset his cost for rebuilding the soil and getting the noxious weeds under control This has also been hit and miss and as far as I know, Gary has only planted once or twice over the last 5 years This is a dryland farm and we do not own any water rights The Spear canal and Irrigation ponds located on the property to our South is on Olson family land, so we do not have access to that water In March of 2019, Gary and I started discussing the possibility of installing center pivot irrigation, but this is still limited due to lack of water The only available water would be applying effluent water from the Bella farms dairy holding ponds which are located to the Northwest of our location This is approximately one mile away Gary told me that this would only be used once or twice a season and this would not be suitable for continuous use Gary did place a 6" pipeline under WCR34 coming from the S/E corner of his property into our N/W corner The intent was to tie into this for irrigation so he could hopefully plant yearly crops To date, nothing has happened, and a center pivot irrigation system has not been installed He does not plan on farming the corners and at best this might produce some dryland crops Solar Farming option The opportunity to generate income from the property has been severely restricted now that the oil & gas wells have been shut down and the fact that we do not have access to irrigation Even with the possible use of effluent water this would still be considered dryland farming and would only pay $20 00 per acre So early this year I started to investigate other options to improve the owner's income That is when I started working with Page 1 of 3 November 30th, 2020 Sun Share We started working on layouts to allow Sun Share to build a usable solar array while still allowing Gary the opportunity to set up a center Pivot irrigation system The proposed plan achieves this goal and gives Bella Farms the opportunity to set up a 270° center pivot system Allowing Bella farms to continue to grow feed for their dairy cows and Sun Share to harvest the sun's energy The owners are excited not only to have the opportunity to additional receive income but to also put the land to good use by providing electricity for the surrounding community The Owners Group The owners are direct descendants from John & Mirth Kugel John only had one daughter, Patty (Leonard) Wilcox from a previous marriage John later married Mirth but they never had any children John and Mirth set it up so Mirth's Nephews and niece would also become part owners upon their passing The owners of six family lines Three are from John and Three from Mirth Johns daughter Patti passed away during 2016 and she left her shares to Daughters, Cynthia Walters, Paula Carr, and grandson Troy Skogmo For Mirth, it is Gary Kugel, Brain Kugel, and Key (Kugel) Sachs Together this family makes up the owner's group I am sad to say that my wife Paula just passed away on 10/2020 from brain cancer Her two children will now become part owners of the farm It was John and Mirth's di earn that this property would continue to piovide for then airs This project will allow the farm to keep producing income while helping the local dairy and community Paula Carr I would like to share some information about my wife Paula Paula was an amazing woman and so full of life She loved her grandparents and adored her grandfather Paula grew up in Washington but would spend many summers with her grandparents John and Mirth lived in their home in Longmont but owned four different farm properties John would commute to the farms to work on them He would grow crops every single year and this was their only source of income John was also a pilot from WW2 and continued to fly throughout his life John and Mirth belong to the Flying farmer's group and enjoyed fly -ins every year with other farmers He kept his plane just South of the Platteville farm at a private airstrip Paula uses to enjoy packing lunch for John Mirth would take Paula and her sisters out to the farms for picnics with John Later as Paula become a young adult, she would continue to spend time lots of time with her grandparents She even moved to Colorado to be closer to them John was also was a private pilot instructor and started teaching Paula to fly Paula's mother Patti also adored her father and spent many wonderful months over the years in Longmont and on the farms When Patti asked me to help manger the properties her only request was that I try to get the farms back into condition but also work with the oil companies When Patti passed away, Paula asked me if I would continue working the farms Paula knew we had serious problems with trying to keep the Platteville farm in the crop We did look at the possibility of trying to subdivide the farm into horse properties She did not really care for this because she wanted to see it stay as farmland Knowing we did not have the capital or farming experience, we knew we could not farm the property My career as being in residential/commercial construction, which is why we looked at developing the land So, when I approached Paula about setting up a Solar Farm, she was excited She said to me that's he loved the idea that we were still farming because this would farm the sun's rays Her exact woids were "The sun used to kiss granddads wheat now it will kiss the solar panels" I got her point, we are still farming but in a high tech way More important is we keep the property generating income for the owner's group Page 2 of 3 November 30`h,
