LaSalle County approves 5-megawatt South Ottawa solar facility with vegetative screening conditions

The LaSalle County Board on April 10 approved a special-use permit for a proposed 5-megawatt commercial solar energy facility on North 270 Third Road in South Ottawa Township, after adding conditions intended to screen the project from a nearby subdivision.

The board voted to grant petition 25-08 filed by Martin 3 Ventures LLC / South Ottawa Township Solar LLC, adopting the LaSalle Zoning Board of Appeals recommendation and six conditions for approval, including compliance with Illinois Department of Natural Resources and LaSalle County Soil and Water Conservation District recommendations; posting maintenance contact signage; vegetative maintenance and weed control during construction and operation; and submission of a full vegetative management plan before issuance of a building permit. The board amended the proposed vegetative screening condition to require two staggered rows of native evergreen plantings with minimum planted heights of 7 feet in the northeast corner and 5 feet elsewhere along the perimeter.

County planning staff described the project as a 5-megawatt commercial facility with a combined Lisa (land evaluation/site assessment) score of about 177.96 (site assessment 85, land evaluation 92.96). The petition had unanimous approval from the Zoning Board of Appeals, subject to the conditions.

Board members asked about screening, site location and road agreements for access and maintenance. Staff said a road agreement would be required prior to issuance of building permits and noted the statutory framework for county standards for solar energy facilities. Members also discussed decommissioning and bonding: staff said the county retains decommissioning language and that operators typically post bonds or other financial assurances and that decommissioning would be required if the facility ceased operation.

Several commissioners raised policy and planning concerns: some said they worry about loss of agricultural land and proximity to parks and subdivisions; others stressed property-owner rights and noted leases commonly run 20–35 years and can be renewed. The sponsor emphasized the conditions added to the permit were intended to reduce visual impacts on nearby residents.

The roll-call vote recorded 18 ayes, 7 nays and 1 abstention; the board declared the motion carried.

Votes at a glance: petition 25-08 special-use (Martin 3 Ventures LLC / South Ottawa Township Solar LLC) — approved (18 ayes, 7 nays, 1 abstention).

The board’s approval includes required pre-construction submittals (vegetative management plan) and typical county requirements for maintenance, screening and road agreements; staff said those conditions must be satisfied before a building permit is issued. The county also retains decommissioning requirements and will hold performance assurances in the Treasurer’s Office.

The petition and conditions were read into the record during the Land Use portion of the meeting and appear in the county’s ordinance language for special uses. The board’s action does not itself construct the facility; it authorizes a special use subject to compliance with the listed conditions and applicable state statute.
