USE BY SPECIAL REVIEW (USR)
PLANNING QUESTIONNAIRE
Answer the following questions per Section 23-2-260. A, B, C & E of the Weld County Code. Please type on a
separate sheet. If a question does not pertain to your proposal, please respond with an explanation — do not
leave questions blank.
1. Explain the proposed use and business name.
The proposed use is a solar energy facility called "Longs Peak Community Solar Garden". The
applicant is Namaste Solar Electric Inc but this project will be owned by UXl County Road 8319 LLC.
2. Explain the need for the proposed use.
The project provides locally produced clean energy to Weld County residents.
3. Describe the current and previous use of the land.
The land is currently used for agricultural production.
4. Describe the proximity of the proposed use to residences.
The proposed project is approximately 1000' from the nearest residence, not including the residence
on the parcel owned by our landlord. We have designed the site such that the required retention
pond is placed between the residence and the solar project to act as further buffer. There is also an
old shed in the buffer zone as well as existing mature trees and landscaping.
5. Describe the surrounding land uses of the site and how the proposed use is compatible with them.
The surround land uses are agricultural and industrial (airport). Through the use of holistic and
regenerative land management, our project will actually improve the soil health and biodiversity,
while making the area less prone to erosion than it was prior to the solar installation. When our
temporary facility is decommissioned in 20-30 years, the parcel will be restored to its original
condition and will be able to continue producing agriculture.
6. Describe the hours and days of operation (i.e. Monday thru Friday 8:00 a.m. to 5:00 p.m.).
The facility produces energy from sunrise to sunset, 365 days a year. It is unmanned.
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.
Once constructed, the facility is unmanned.
8. Describe the maximum number of users, patrons, members, buyers or other visitors that the site will
accommodate at any one time.
Once constructed, the facility is unmanned, except for routine operations and maintnenance visits
1-2 times per year.
9. List the types and maximum numbers of animals to be on the site at any one time (for dairies, livestock
confinement operations, kennels, etc.).
There will be no animals permanently on site; the use of holistic land management may cause sheep
to be grazed on the property in lieu of mechanical vegetation management when needed for
approximately I week at a time. (likely 2x per year, total).
10. List the types and number of operating and processing equipment.
Not applicable.
11. List the types, number and uses of the existing and proposed structures.
There are no traditional "structures" i.e. buildings/refineries, etc.. on site. The site will host solar
panels which are laid atop driven El -beam piles throughout the site.
12. Describe the size of any stockpile, storage or waste areas.
Not applicable.
13. Describe the method and time schedule of removal or disposal of debris, junk and other wastes associated
with the proposed use.

The lot surface will remain dirt and native vegetation. There is an existing driveway/access road.
There will be a small apron of gravel or compacted native soil installed at the entrance to the site
off of the private driveway.
16. How many parking spaces are proposed? How many handicap -accessible parking spaces are proposed?
Not applicable.
17. Describe the existing and proposed fencing and screening for the site including all parking and outdoor
storage areas.
We are proposing an 8' decorative, wildlife friendly agricultural fence to surround the site which is
typical for this type of project in Weld County, and in line with the Colorado Parks and Wildlife
referral request.
18. Describe the existing and proposed landscaping for the site.
There is existing mature vegetation around the residence on the SouthWest side of the property.
Beyond the decorative fence, we are not proposing additional landscaping at this time.
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.
Generally, decommissioning of a Solar Facility proceeds in the reverse order of the installation.
1.The Solar f=acility is disconnected from the utility power grid.
2.PV modules are disconnected, collected, and disposed at an approved solar module recycler or
reused / resold on the market.
3.All above ground and underground electrical interconnection and distribution cables are
removed and disposed off -site at an approved facility.
4.Galvanized steel PV module support and racking system support posts are removed and
disposed off -site at an approved facility.
.Electrical and electronic devices, including transformers and inverters shall be removed and
disposed off -site by at approved facility.
.concrete pads (which exist only for the utility transformer and related equipment) are removed
and disposed off -site at an approved facility.
].Fencing is removed and will be disposed off -site by at approved facility.
20. Describe the proposed fire protection measures.
The access road will be designed to accommodate a turnaround by an emergency vechicle and an
approved Knox box will remain at the entrance to the site to allow access by EMS if necessary.
21. Explain how this proposal is consistent with the Weld County Comprehensive Plan per Chapter 22 of the
Weld county Code.
The guiding principles of the Weld county comprehensive plan includes 4 main sections: A)
Respecting agricultural heritage. Our proposed development improves the soil quality and
biodiversity and allows for improved agricultural production after our temporary facility is
decommissioned. B) Respecting private property rights: our local landowner partner who is hosing
this development has made a decision that he and his wife would like to use their property to host
and accrue revenue from a solar energy facility. C) Promoting Economic Growth and Stability: This
project will not only bring revenue into Weld County through a substantial additional tax base, but it
will provide economic support to the local community through the construction timeline as well as
as a stable and long term revenue stream to our landowner partner.
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.)
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. Our
project is energy development.
23 Explain how this proposal will be compatible with future development of the surrounding area or adopted
master plans of affected municipalities.
Our project is temporary, by nature, and thus it will not impact the long-term master plan of the
surrounding communities and municipalities. While in operation, it will provide clean energy to local
residents and businesses.
24. Explain how this proposal impacts the protection of the health, safety and welfare of the inhabitants of the
neighborhood and the County.
This project provides clean energy to local residents and businesses.
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.
Through the use of holistic and regenerative land management, our project will actually improve the
soil health and biodiversity, while making the area less prone to erosion than it was prior to the solar
installation. When our temporary facility is decommissioned in 20-30 years, the parcel will be restored
to its original condition and will be able to continue producing agriculture.
26. Explain how this proposal complies with Article V and Article Xl 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 bymaps officially adopted by the County.
The max height of the solar panels is 10' above ground level and as such well under the height
limitation of the Airport overlay district. This is an unlit facility and as such will not interfere with
pilots navigating to the airport at night. Lastly, this project does not emit any electrical signals that
could cause interference with the radio communications between the pilots and control tower, if
applicable.
The area of our project in a flood plain will be permitted by Weld County planning department. The
piles will be elevated above the FEMA flood elevation. Details can be found on the detail on page
El 01 of our associated USR Plan set.
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.
State SWPP to be applied for post entitlement in coordination with building permit.

SUPPLEMENTAL REQUIREMENTS
The supplemental submittal requirements and review procedures are stated in Chapter 23, Article IV, Division 15 of the
County Code. The Weld County Code is available online at www.weldgov.com (Useful Links > Weld County Code).
Submit all the application components as separate documents, in PDF format, in the order outlined in the checklist below.
In addition to the standard USR map requirements, show the 30 -foot solar facility setback from the
property line, irrigation ditches and rights -of -way per Section 23-4-1030.G of the Weld CountyCode.
Done.
Reasonable alternative analysis per Section 23-4-1030.0 of the Weld County Code.
Finding land that is appropriate for solar is an extremely challenging task. We hired an outside agency
and spent incredible amounts of time and money searching for a parcel that met our needs. With the
Bird site we found property owners who were excited about exercising their rights to use their private
property in a unique way to provide additional secure revenue for their family. The parcel is close
enough to utility infrastructure that we can relatively easily interconnect our system into the utility grid
to send power back to local residents. We also selected to use the part of the parcel that is off the
frontage with limited exposure to any residences in consideration of any possible viewshed concerns.
The nature and location of this facility will not unreasonably interfere with any irrigation systems or
other activities in the area. We scoured reasonable alternatives and can confidently say this is an
appropriate site to host this solar energy facility.
Irrigation mitigation statement per Section 23-4-1030.E of the Weld County Code.
The nature and location of this facility will not unreasonably interfere with any irrigation systems on or
adjacent to the solar facility.

USE BY SPECIAL REVIEW - SOLA►R
CODE REQUIREMENTS
Per Section 23-4-1030 of the Weld County Code.
A. The staff, Planning Commission and Board of County Commissioners shall consider the following criteria in making
their determination in approving or denying a permit for a Solar Facility in addition to those criteria enumerated in
Chapter 23, Article II, Division 4 and its impact on prime agricultural land which is defined as soils with agricultural
capability classifications of I, II and III as indicated on maps completed by the U.S.D.A. Natural Resources Conservation
Service.
B. A Decommissioning Plan. Adequate financial assurance to cover the decommissioning of the facility may be required
as a condition of approval of the Decommissioning Plan.
C. Landscaping is extremely important for enhancing the quality of DEVELOPMENT in the area. Trees, shrubs and other
plantings add greatly to the aesthetic appeal while reducing glare. As no single landscaping plan can be prescribed for
all DEVELOPMENTS due to differing land features, topography and soils, these guidelines encourage flexible and
creative landscape designs. Landscaping/SCREENING shall include, at a minimum, decorative fencing, berming,
and/or vegetation such that the facility is aesthetically pleasing as viewed from ADJACENT properties and RIGHTS -
OF -WAY.
D. All reasonable alternatives to the proposed location have been adequately assessed, and the proposed action is
consistent with the best interests of the people of the COUNTY and represents a balanced USE of resources in the
affected area.
E. The nature and location or expansion of the facility will not unreasonably interfere with any irrigation systems on or
adjacent to the solar facility.
F. No OUTDOOR STORAGE of any materials and equipment including, but not limited to, solar panels and support
STRUCTURES not in operation will be allowed.
G. No equipment associated with the solar facility shall be located nearer than thirty (30) feet to the boundary of ADJACENT
properties, irrigation ditches and/or RIGHTS -OF -WAY. The Board of County Commissioners may set a greater distance
than mentioned above when, in its opinion, it is justified.
H. A Property Maintenance Plan is required for the facility. The Property Maintenance Plan shall address dust, weeds and
erosion. The property shall be maintained in such a manner as to control dust, weeds and drainage that could cause
erosion.

LONGS PEAK COMMUNITY SOLAR GARDEN
Decommissioning Plan/Statement — March 16, 2021
Namaste Solar Electric, Inc. and Unico Solar Investors, through affiliate UXI County Road
8319 LLC ("Project Owner"), proposes to build a photovoltaic (PV) solar facility ("Solar
Facility") near 21649 County Road 62 in Weld County. The Solar Facility is planned to have
an aggregate nameplate capacity of approximately 4.00 megawatts (MW) direct current (DC)
and be constructed on private land ("Project Site") leased by the Project Owner from the
property owner ("Property Owner").
The Solar Facility will have a useful life of thirty (30) years. The lease agreement ("Lease")
between the Project Owner and Property Owner has a twenty (20) year lease term, subject to
two five (5) year extensions at the Option of Owner. The Lease has been executed.
At the time of decommissioning, the installed components will be removed, reused, disposed of,
and recycled, where possible. The Project Site will be restored to a state similar to its pre -
construction condition. All removal of equipment will be done in accordance with any applicable
laws and regulations, including without limitation, the local laws of the County applicable to
solar energy systems, and manufacturer recommendations. All applicable permits will be
acquired.
LONGS PEAK COMMUNITY SOLAR GARDEN
Property Maintenance Plan — March 16, 2021
Namaste Solar Electric, Inc. and Unico Solar Investors, through affiliate UXI County Road
8319 LLC ("Project Owner"), proposes to build a photovoltaic (PV) solar facility ("Solar
Facility") near 21649 County Road 62 in Weld County. The Solar Facility is planned to have
an aggregate nameplate capacity of approximately 4.00 megawatts (MW) direct current (DC)
and be constructed on private land ("Project Site") leased by the Project Owner from the
property owner ("Property Owner").
The Solar Facility will have a useful life of thirty (30) years. The lease agreement ("Lease")
between the Project Owner and Property Owner has a twenty (20) year lease term, subject to
two five (5) year extensions at the Option of Owner. The Lease has been executed.
The property shall be maintained in such a manner as to control dust, weeds and drainage that
could cause erosion. The weeds shall be maintained through a combination of animal grazing,
mechanical and herbicidal mitigation and control as permitted by the local jurisdiction.
The SWMP and drainage plan speak to the drainage of the site and maintenance thereof From
a seeding standpoint, the exact mix will be based on time of year, but seed is to be no -till
drilled immediately after site grubbing. Touch up seeding during and post construction to be
done via broadcast, specific seed mix to be determined by time of year. Intention of the mix
is to meet SWMP requirements, while simultaneously improving soil health and creating
forage for planned managed sheep grazing post-SWMP NOT.
Managed grazing and mechanical mowing will then be used to assist in establishment for 3 -
years, care will be taken that grazing does not negatively impact establishment efforts. During
the 3 -year establishment period, seed from Permanent Mix and Temp mix will be broadcast
as needed to address bare spots and prevent/halt any developing erosion. After the 3 -year
establishment period, it is expected that the Shortgrass+Pollinator mix will be dominant
species composition, and Temp seeding can decrease.
There is not anticipated to be any dust due to the lack of traffic on site during the operational
phase. If needed during the construction phase, dust mitigation efforts may be implemented
via a water tanker driven on site spraying water over the affected areas preventing dust from
becoming airborne. We do not anticipate this to be necessary.

Project Site
This Drainage Report has been prepared on behalf of UXI County Road 8319 LLC for the
proposed construction of the Longs Peak Solar Facility in Weld County, Colorado hereinafter
referred to as the project.
The proposed development is located in the SE1/4 Quarter of Section 34, Township 6 North, and
Range 65 West of the 6th Prime Meridian. More specifically the Project site is approximately
16.41 acres of land and is located approximately 2.2 miles northeast of Greely and approximately
1.2 miles northeast of the intersection of Weld County Road (WCR) 43 and Highway 263 in
Weld County, Colorado. The site is covered intermittently with agricultural row crops depending
on time of year. The ground surface slopes to the southeast at an average slope of approximately
0.40%. The site contains FEMA Zone A flood hazard. A FEMA Zone A flood hazard is a loo -year
flood hazard with no base flood elevation determined. The site is therefore within a loo -year
floodplain.
General Description of Project
It is proposed to develop approximately 16.41 acres of land for the project of an approximate
6.98 MW solar array. The solar array will deliver renewable energy to the Cloverly Substation
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 the solar panels will be planted with a 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 5,445 square feet
and 877 square feet, respectively. Per Weld County Public Works solar panels are considered
25% impervious on soils belonging to Hydrologic Soil Groups C and D. Given this, the site will
need a detention pond per Weld County requirements. In proposed conditions runoff will
continue to sheet flow to the southeast as it does in existing conditions, and be routed to the
basin southwest of the solar array. This basin will outlet into the ditch to the west of the site.
Historically stormwater runs southeast then continues southeast. 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 C
(Attachment 4) are minimally conducive to infiltration. The soil type was also categorized as a
clay loam for the runoff coefficient. The fully vegetated site will slow runoff and encourage
partial infiltration.
Stormwater Runoff Analysis
A detention pond has been sized to store the stormwater runoff generated by the 1 -hour, loo -
year storm falling on the developed site and release of the detained water at the historic runoff
rate of the 1 -hour, 10 -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
2 I Confidential and Proprietary. TBPLS Firm #10074302
Drainage Report I Longs Peak Community Solar Garden March 15, 2021
was used to determine the runoff rates for the project. These calculations can be found in
Attachment 3.
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 the WQCV that needs to be captured based on a site imperviousness of 22% is 0.12
watershed inches which requires a BMP storage of 0.169 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
The only proposed drainage improvement 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 0.97
ac -ft and reduces runoff for all of the storm events. The existing and proposed runoff rates can
be seen in Table 1 below.

Sand Creek flows north to south just west of the project area, and the site contains a FEMA Zone
A floodplain surrounding this creek. However, it appears that this floodplain was mapped based
on older elevation data. Based on current elevation data, Sand Creek flooding impacts to the site
are not anticipated. Minor runoff from the northern and western portions of the parcel sheet
flows onto the project site and continues southeast. This water will pass through the basin.
Onsite Soils
The soils for this project site are classified as hydrologic soil group C (Attachment 4). The soil
types found in the project site area are Dacono Clay Loam, with o%-i% and 1%-3% slopes. This
soil information is based on the Natural Resources Conservation Service (NRCS) National
Cooperative Soil Survey. The runoff coefficient typically referred to as a "C" value in Attachment
3 is larger in proposed conditions than in existing conditions, causing an increase in post -
construction runoff, which is reduced to less than existing rates by the addition of the extended
detention basin.

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 C 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 runoff
rates of different land covers. Rainfall data was obtained from NOAA Atlas 14 (Attachment 2).
Minimal grading is proposed to meet the tolerances of the proposed solar array. Drainage
patterns will remain the same across most of the site, with the exception of routing runoff from
the southeast portion of the site to the southwest basin, which in turn outlets into the ditch west
of the site. Outside of the basin minimal grading is proposed onsite and drainage conditions will
remain the same as existing across the remainder of the site. The 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, 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 stages of construction.
BMP Installation, Inspection, and Removal
BMPs will be installed prior to project construction, except for 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 Fertile Loamy Soil Seed Mix to establish
permanent stabilization after construction activity has ceased. Reference the Temporary and
Permanent Seeding Table on page EC -2 of Chapter 7: Construction BMPs in the USDCM
Manual, Volume 3. 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 to
more than 3/4 inch, and crimping the seeded areas in straw mulch at a rate of 2 tons per acres to
provide immediate erosion protection.
Summary
The proposed site will be designed to maintain its existing drainage patterns across most of the
site, and then route runoff into the southwest basin which will outlet into the ditch just west of
the site. The extended detention basin will contain storage for the Water Quality Capture
Volume and 1oo-year storm, and reduce runoff rates from existing conditions to proposed
conditions.

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.

MAP INFORMATION
The soil surveys that compnse your AOI were mapped at
1 24,000.
Warning Soil Map may not be valid at this scale.
Enlargement of maps beyond the scale of mapping can cause
misunderstanding of the detail of mapping and accuracy of soil
line placement. The maps do not show the small areas of
contrasting soils that could have been shown at a more detailed
scale.
Please rely on the bar scale on each map sheet for map
measurements.

Coordinate System Web Mercator (EPSG 3857)
Maps from the Web Soil Survey are based on the Web Mercator
projection, which preserves direction and shape but distorts
distance and area. A projection that preserves area, such as the
Albers equal-area conic projection, should be used if more
accurate calculations of distance or area are required.

Description
Hydrologic soil groups are based on estimates of runoff potential. 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 (AID, 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.
