|Solar Allowed on Which Zoning Designations
|Small solar energy facilities allowed on all zoning with by site plan review or special review.
Medium solar energy facilities allowed on forestry, agricultural, rural residential, and estate residential with limited impact special review or special review. Medium solar energy facilities allowed on transitional, business, commercial, light industrial, and general industrial through site plan review.
Large solar energy facilities allowed on forestry, agricultural, rural residential, and estate residential with special review. Large solar energy facilities allowed on transitional, business, commercial, light industrial, and general industrial through limited impact special review.
|Allowed in ag-rural and near-urban planning areas. Size of SEF depends on which area. SEF allowed on I-1 zoned parcels through administrative process. SEF not allowed on residential except for private use on-site. For medium or large SEF: A statement which explains that if the USE is proposed to be located in the A (Agricultural) Zone District, the applicant has demonstrated a diligent effort has been made to conserve prime agricultural land in the locational decision for the proposed USE.
|Solar on Agricultural Lands
|>0.5 acre on significant agricultural lands requires Solar Energy System Development Report. Total disturbed areas associated with the ground-mounted system cannot exceed 7 acres on parcels smaller than 70 acres in size, or 14 acres on parcels larger than 70 acres in size.
|No system greater than 30 MW in Agricultural zone.
|Small solar energy facilities require Uses Permitted by site plan review or special review.
Medium solar energy facilities require Uses Permitted by limited impact special review, special review or, site plan review.
Large solar energy facilities require Uses Permitted by special review or limited impact special review.
All permits require a Land Use Review Pre-Application Conference with a Planner to discuss the proposal.
|Small solar energy facilities require a zoning permit, which is processed administratively.
Medium and Large facilities require Use by Special Review (USR) or 1041 permits, respectively. These permits require Planning Commission and Board of County Commissioner review and approval.

Comment From Weld County Officials:
|Ground-mounted systems shall not exceed 15 feet in height, except to accommodate site specific needs and as approved through review.
Systems exceeding 15 feet in height require an increased setback of 75 feet from all property lines, unless it is demonstrated that a lesser setback or topographical or vegetative screening adequately mitigates visual impacts.
In no case shall a system exceed 25 feet in height.
|Ground-mounted solar collectors shall not exceed 25 feet, measured from the highest grade below each solar panel to the highest extent of the solar panel rotation.
|110 feet from center line of roads
100 feet from property lines
|Small Solar System – shall conform to the setback requirements of the underlying zone.
Additionally, the improved area must be at least five 500 feet from existing residential buildings and residential lots of a platted subdivision or planned unit development. The residential setback requirement may be reduced if appropriate screening through landscape or an opaque fence is installed, or upon submittal to Weld County of a waiver or informed consent signed by the residence owner agreeing to the lesser setback. If landscaping or opaque fencing is substituted for setback, a landscaping plan or fencing plan shall first be submitted to and approved by the Department of Planning Services.
|Small Solar System – operators shall continuously employ the practices for control of fugitive dust detailed in their dust mitigation plan submitted
|Small Solar System – shall be designed, located, or placed so that concentrated solar glare from its solar collectors will not be directed toward or onto nearby properties or roadways at any time of the day
|Erosion control and revegetation plan. Location of existing and proposed landscaping including a revegetation plan. The site plan shall illustrate the type, height, and/or caliper of the trunk of proposed plantings. All plantings will be specified by type and
|The Dust Mitigation Plan shall be provided at the time of 5 ACRE SEF application submittal, which includes a description of those methods by which dust emanating from the proposed 5 ACRE SEF and the weeds growing upon the Impacted Area will be mitigated
|Small Solar System – shall be enclosed with a security fence as approved pursuant to a fencing plan submitted to the Department of Planning Services
|Screening / Vegetative Barrier
|Only if the array exceeds the 15-foot height requirement
|Only required if the array will be less than the required setback from residential buildings
|Decommissioning / Reclamation Plan
– All disturbed will be reclaimed and revegetated to the satisfaction of the County, in consultation with the landowner
– Revegetation and reclamation will include, but is not limited to, the use of native plant species when appropriate, integrated management of weed control and prevention, and full establishment of appropriate vegetation for a minimum of three consecutive growing seasons
– No species on List A, B, or C in the County’s Noxious Weed Management Plan may be used to meet revegetation requirements
Reclamation cost estimates, which shall be updated every 5 years from the establishment and submittal of the Security, shall include all costs associated with the dismantlement, recycling, and safe disposal of facility components and site reclamation activities, including the following elements:
a) All labor, equipment, transportation, and disposal costs associated with the removal of all facility components from the facility site
b) All costs associated with full reclamation of the facility site, including removal of non-native soils, fences, and constructed access roads
c) All costs associated with reclamation of any primary agricultural soils at the facility site to ensure each area of direct impact shall be materially similar to the condition it was before construction
d) All decommissioning/reclamation activity management, site supervision, site safety costs
e) Any other costs, including administrative costs, associated with the decommissioning and reclamation of the facility site
f) The estimated date of submission of the Security to Weld County
|Decommissioning / Reclamation Bond
|Prior to construction:
An irrevocable standby letter of credit, bond, or alternate form of Security in an amount sufficient to fund the estimated decommissioning/ reclamation costs required by this Code.
